Abstract

Background Indigenous communities in Peru has been historically affected by high mortality rates attributable to HIV-AIDS infection, associated with a low access to health services, and socio-cultural barriers. In this context, the study aimed to describe factors associated with antiretroviral treatment adherence in people from Awajun and Wampis indigenous communities, living with HIV-AIDS in a Peruvian Amazonian region. Methods A cross-sectional study was completed with a consecutive sample of people from indigenous communities (Awajun or Wampis) living with HIV, who were receiving antiretroviral treatment for at least the last three months. Participants were recruited between October 1 and December 30, 2021, from four districts of Bagua and Condorcanqui provinces in the Amazonian region. An ad-hoc questionnaire was used to collect information about demographic, economic, and socio-cultural factors and access to health services. The Simplified Medication Adherence Questionnaire (SMAQ) was used to evaluate adherence to antiretroviral therapy. Multivariate logistic regression analysis with backward stepwise was performed to explore factors that might influence adherence. Results Of the 208 participants, 28.8% reported complete adherence to antiretroviral treatment. The multivariate logistic regression showed that occupation (aPR: 1.86; 95%CI 1.15–3.02), economic income (aPR: 0.64; 95%CI 0.41–0.99), and adverse reactions to antiretroviral therapy (aPR: 0.36; 95%CI 0.18–0.70) were related to complete adherence to medication. Conclusion Only a third of participants reported complete adherence to antiretroviral therapy. Factors associated with adherence to antiretroviral medication were related to socioeconomic conditions and adverse reactions to the therapeutic scheme.

Abstract
Background Indigenous communities in Peru has been historically affected by high mortality rates attributable
to HIV‑AIDS infection, associated with a low access to health services, and socio‑cultural barriers. In this context,
the study aimed to describe factors associated with antiretroviral treatment adherence in people from Awajun and
Wampis indigenous communities, living with HIV‑AIDS in a Peruvian Amazonian region.
Methods A cross‑sectional study was completed with a consecutive sample of people from indigenous communi‑
ties (Awajun or Wampis) living with HIV, who were receiving antiretroviral treatment for at least the last three months.
Participants were recruited between October 1 and December 30, 2021, from four districts of Bagua and Condorcan‑
qui provinces in the Amazonian region. An ad‑hoc questionnaire was used to collect information about demographic,
economic, and socio‑cultural factors and access to health services. The Simplified Medication Adherence Question‑
naire (SMAQ) was used to evaluate adherence to antiretroviral therapy. Multivariate logistic regression analysis with
backward stepwise was performed to explore factors that might influence adherence.
Results Of the 208 participants, 28.8% reported complete adherence to antiretroviral treatment. The multivariate
logistic regression showed that occupation (aPR: 1.86; 95%CI 1.15–3.02), economic income (aPR: 0.64; 95%CI 0.41–

to medication.
Conclusion Only a third of participants reported complete adherence to antiretroviral therapy. Factors associated
with adherence to antiretroviral medication were related to socioeconomic conditions and adverse reactions to the
therapeutic scheme. Interventions to improve adherence in indigenous people living with HIV should consider these
factors in order to develop effective implementation strategies.

Background
e introduction of highly active antiretroviral therapy
(ART) has converted HIV infection from a terminal
disease to a treatable chronic disease. However, even
though ART improves the clinical, immunological, and
viral response, it requires maintaining a high level of
adherence to the prescribed therapy due to the danger
of an increase in viral activity and the development of
resistance to these drugs [1]. In recent years, non-adher-
ence to ART has become a complex public health prob-
lem with many associated factors that are related to the
social, economic, and cultural context of people living
with HIV. e World Health Organization (WHO) sug-
gests that these factors can be classified into four dimen-
sions: characteristics of the therapeutic scheme, patients’
characteristics, the relationship between healthcare
providers and patients, and the proper characteristics
of health systems. In the patient’s characteristics, one of
the most important factors are the belief systems about
health and disease that people should have due to their
sociocultural context [2].
Indigenous populations are one of the groups most
affected by the consequences of HIV infection and lim-
ited access to healthcare. Previous research has found
that indigenous populations have higher rates of incom-
plete adherence or complete discontinuation of ART
compared to the general population, possibly due to
factors related to their cultural uniqueness and their
views or interpretations about disease and conventional
treatments, as well as social aspects such as geographi-
cal barriers, access and availability of monitoring, etc
[35]. us, this situation suggests that public health
strategies to control the transmission of HIV in indig-
enous populations should be developed using a multi-
level approach based on human rights and integrating
traditional practices that can help reduce vulnerability
to transmission [6].
Peru is one of the Latin American countries with the
largest number of indigenous populations in the region.
According to official records, in 2017, there were 44
indigenous populations in 2703 communities at the
national level [7]. On the other hand, the epidemiology of
the HIV/AIDS infection in Peru still has characteristics
of a concentrated epidemic, with an estimated prevalence
of 0.3% in adults older than 15 years, an incidence rate
of 0.20 per 1000 inhabitants, with approximately 1000
deaths per year [8, 9]. Awajun and Wampis are Amazo-
nian indigenous populations, who represent 35.8% of the
total indigenous population affected by sexually trans-
mitted diseases, including HIV infection [7].
e Amazonas Region concentrates 13.4% of the
Peruvian indigenous communities, with an impor-
tant presence of Awajun and Wampis populations.
According to statistics from the Regional Health Direc-
tion, the districts with the most presence of Awajun
and Wampis populations report more than 70% of HIV
infection cases from the entire region [10]. ere is
some preliminary evidence which suggests that the con-
ception and social representations of health and disease,
especially in the case of HIV infection in people belong-
ing to these indigenous populations, strongly influence
the behaviors that they finally present before the health
interventions that the conventional health system tries
to impose [1113]. However, there has been no evi-
dence found related to factors influencing ART adher-
ence in these populations. erefore, this study aimed
to describe factors associated with antiretroviral treat-
ment adherence in people from Awajun and Wampis
indigenous communities living with HIV-AIDS in four
districts from a Peruvian Amazonian region.
Methods
Study design andparticipants
is was a cross-sectional study that included people
living with HIV, who were over 18 years old, from Awa-
jun or Wampis communities, who were living in the dis-
tricts of Santa María de Nieva, El Cenepa, Río Santiago,
and Imaza (Amazonas Region-Condorcanqui and Bagua
provinces), and who had an ART prescription for at least
three months before the survey application. People who
had not received ART in the last three months because
of supply or logistical problems, previous failure of ART
or ART resistance, or who could not express themselves
or did not sign the informed consent form were excluded
from the study. Participants were included using a non-
probabilistic sampling by convenience.
Participants were recruited between October 1 and
December 30, 2021. In this context, according to medi-
cal records reviewed before the survey application, there
were 292 people living with HIV in the four districts that
would be evaluated in the study. e cases were distrib-
uted as follows: 82 in Santa Maria de Nieva district, 104
in Cenepa district, 42 in Rio Santiago district, and 64 in
Imaza district.
e study was approved by the Ethical Review Board
from the Instituto Nacional de Salud-Peru (RD N°
065-2020-DG-OGITT-OPE/INS). An informed consent
process was applied in the local language, explaining the
study’s aims and participation implications to the partici-
pants. Only participants who signed the informed con-
sent form were included in the study.
Assessment ofART adherence
ART adherence in last three months were evaluated with
the Spanish adapted version of Simplified Medication
Adherence Questionnaire (SMAQ) [14]. e SMAQ has

been used in previous research [15] and as a monitor-
ing instrument in health public services in Peru [16]. e
questionnaire has six items with dichotomous answers
(Yes/No):
1. Do you ever forget to take your medication?
2. Did you always take your medications at the right
time?
3. Do you ever stop taking your medicine if you feel
sick?
4. Did you forget to take your medication over the
weekend?
5. I have not taken more than two doses in the last
week.
6. Did you forget to take the medicine more than two
days, in the last three months?
It was considered as a “non-adherent” anyone who had
a positive answer to any of the six questions. For the last
two questions, a positive answer was considered when
the participant indicated forgetting to take medication
for two or more doses in the last week, or for more than
two days in the last three months.
Assessment ofpossible associated factors
Data related to personal characteristics (age, gender,
civil status, educational level, occupation, religion,
monthly income, alcohol, tobacco or drug consump-
tion, family members and migration), clinical features
(disease time, risk population, opportunistic infections),
factors related to ART (therapeutic scheme, adverse
events), sociocultural factors (disease conceptualization,
medicinal plant use, attention by traditional medicine
agent, familiar support, social support, stigmatization,
and discrimination) and healthcare access (healthcare
insurance, time to the nearest health centers, transport
expenses to health centers, expenses in ART medica-
tions) were evaluated by an ad-hoc format developed by
the research team based on a previous literature review
(view Supplementary Material) [13]. at instrument
was previously validated by experts.
Data about social support and familiar support were
collected with a Likert scale with five categories (very
well, well, regular, bad, very bad), according to the con-
cept proposed by the national framework of integral
attention of people living with HIV, developed by the
Ministry of Health (Peru) [17]. In the same way, data
about clinical features and ART schemes were collected
according to the recommendations of the same docu-
ment (view Supplementary Material). Additionally, infor-
mation about ART features was corroborated with a
review of medical records in local primary care centers.
Data collection procedures
Previously, before conducting surveys, the researchers
collaborated with the regional health direction, health
networks, and primary care centers. ey were informed
about the study and were asked for their cooperation in
providing information about the medical records and
locations of people living with HIV from Awajun and
Wampis communities.
On the other hand, the researchers made official com-
munications with the provincial municipality and com-
munal authorities (“apus”), who signed the collective
informed consent form. At this point, eight local health
professionals with experience in healthcare for these
indigenous communities were identified and trained to
collect data using validated instruments.
e participants were recruited by appointments at the
nearest primary health care center, where trained pro-
fessionals identified potential participants who met the
selection criteria. is process was conducted under the
supervision of the representative of the regional health
direction and the research team.
Each primary health care center was equipped with an
appropriate space to ensure privacy and build confidence
with potential participants. If any participant wanted to
be surveyed in their home, a visit was scheduled, ensur-
ing privacy and confidentiality. e local language was
used during data collection to ensure the quality of the
information.
Statistical analysis
A codified database was created in Microsoft Excel 2016
by two independent typists who were not part of the
research team. Registries with inconsistent or missing
data were excluded from statistical analysis. Descriptive
measures (frequencies, percentages, means or medians,
and standard deviation/interquartile range) were calcu-
lated according to the nature of variables (qualitative or
quantitative).
After that, a bivariate analysis was performed to evalu-
ate the association between possible factors (personal
characteristics, clinical features, factors related to ART,
sociocultural factors, and healthcare access) and adher-
ence to ART. Fisher’s Exact Test or Chi Square Test were
used for qualitative variables; and Student’s t-test for
independent data or Mann-Whitney U for quantitative
variables.
A multivariate analysis was developed through multiple
logistic regression controlling for age, gender, and clinical
stage and considering ART adherence as a dichotomous
outcome (Complete/Incomplete). Crude and adjusted
prevalence ratios (PR) with their corresponding 95% con-
fidence intervals (CI 95%) were calculated to evaluate the

magnitude of found associations. A backward stepwise
selection was performed, considering a significant level
of 0.2 for inclusion in the multivariate model.
Statistical analyses were performed using R 4.0.5, R
Foundation for Statistical Computing, Vienna, Austria.
A p-value less than 0.05 was considered statistically
significant.
Results
General characteristics
e study collected information from 208 participants
from 55 indigenous Awajun or Wampis communities
and 31 primary health care centers. e median age was
25 (22–32) years old, with 57.2% males and 88.9% from
Awajun population. Most of them were single (43.3%)
or reported living with a partner without being married
(45.2%), with a median income of US$ 73.7 (24.6-122.8),
although 47.6% reported not having any income. 174 par-
ticipants were living in a family (83.7%), although 21 par-
ticipants reported living alone and far away from family,
and 13 (6.2%) alone but close to family. 52.4% mentioned
that they did not usually travel to cities.
Most of the participants mentioned that they were
not included in a risk population (80.3%), but 16.8%
reported being included in the group of “men who
have sex with men” (MSM). ere was an approximate
median disease time of 3.6 years, with 24% of partici-
pants who reported having at least one opportunistic
condition at some point. Four cases of tuberculosis-HIV
co-infection were found.
73.1% of participants mentioned that they were using
only ART medications, but 18.8% reported using ART
concomitant with medicinal plants. e first-line thera-
peutic scheme was the most used (39.9%) with a median
treatment time of 2.8 years. 33.2% of respondents
reported having adverse effects during the ART.
When they were asked about their conceptualization
of the disease, the majority (82.7%) referred to a cause
consistent with current knowledge about this disease
(sexual transmission or blood transfusion); however, 13%
of participants referred to concepts of the disease related
to magical-religious origins. Most of the participants
(51.0%) reported receiving poor family support, and
26.9% perceived very poor family support. Additionally,
84.1% reported perceiving stigmatization in their health
facility due to their condition and 86.1% mentioned hav-
ing been discriminated against by being denied care in
health services due to their illness.
Most of the participants reported having state insur-
ance provided by the Ministry of Health - Seguro Inte-
gral de Salud (90.9%), but 4.8% mentioned not having any
health insurance. Additionally, the median time to travel
to the primary care center was 10 (5–30) minutes with
a maximum of five days approximately. 41.3% of partici-
pants reported any type of expense for traveling to the
health center, and 30.8% mentioned making any expense
to buy HIV treatment. Additional information about the
characteristics of participants is explained in Table1.
A complete ART adherence was evidenced in 28.8%
of participants (42.3% in Awajun people and 25% in
Wampis). e dimensions with better accomplishment
were taking medication at the indicated hour (76.0%) and
not stopping to take medication if they felt sick (74.5%).
In contrast, the dimension with the least accomplishment
was forgetting to take medication (53.8%). e results by
SMAQ dimensions are expanded in Table2.
Bivariate analysis
A significant statistical association was found between
ART adherence and marital status (p = 0.011), alcohol-
ism (p < 0.001), adverse reactions to ART (p < 0.001),
and reporting stigma (p = 0.021) or discrimination
(p = 0.003). e complete results of the bivariate analysis
are shown in Table3.
Multivariate analysis
When the multivariable analysis was performed, it was
observed that the interactions of age with the possible
associated factors did not have statistically significant
results, so it was decided to remove this variable as an
adjustment variable, however, age was retained in the
multivariate model.
Finally, it was observed that having an occupation was
associated with a greater probability of having complete
adherence (aPR 1.86; CI 95% 1.15–3.02), while having
any monthly income (aPR 0.64; CI 95% 0.41–0.99) and
reporting adverse effects (aPR 0.36; CI 95% 0.18–0.70)
were related to a lower probability of having complete
adherence. Although a significant effect of clinical stage
was evidenced, it was quite small and with wide confi-
dence intervals due to the small sample size in the study
categories. Complete results of crude and adjusted mod-
els are shown in Table4.
Discussion
is research found that 28.8% of surveyed people had
complete adherence to ART. In urban contexts in Peru,
previous research has found ART adherence levels of
65.1%, which is greater than the values found in this
study [16]. Similarly, Omosanya etal., (2013) found an
ART adherence of 88% in people living with HIV from a
rural tertiary medical center in Nigeria, which suggests
that area of residency is not necessarily a influencing fac-
tor on increasing adherence [18]. In contrast, Chavarry-
Ysla et al., (2020) found an ART adherence of 33% in
people from the Peruvian ethnic group Kusu-Pagata,

which is similar to this study [19]. is is consistent with
other studies in Latin American indigenous communities
with adults living with HIV, which report adherence lev-
els between 20–50%. [20].
No association was found between ART adherence and
personal characteristics. However, the profile is consist-
ent with previous research in indigenous people living
with HIV, with the exception of the gender distribution.
A previous publication about indigenous people from
Bolivia living with HIV reports a 5:3 ratio between males
and women [21], but findings from another publication
that reports the situation in eight Amazonian ethnic
groups in Brazil shows a distribution of 60% of women
affected by HIV infection [22].
An association between having an occupation and
the probability of having complete ART adherence was
found. More than 80% of surveyed people reported liv-
ing with their families and approximately 40% reported
having occasional jobs. ese social factors are closely
related to poverty conditions in the Condorcanqui prov-
ince, which is considered among the top 10 poorest
provinces in the country according to the INEI’s 2018
Monetary Poverty Map [23]. e occupational status has

been proved to be a crucial element in improving ART
adherence in people, regardless of the income classifi-
cation of the countries they are from [24, 25]. Previous
research has hypothesized that the occupational status
could be related to more careful behaviors related to
improving self-care, in order to continue with productive
activities that contribute to maintaining life quality and
health status [25, 26].

In contrast, factors such as having any monthly income
or reporting adverse effects were related to not having
complete adherence. is study found that, in people
who receive a salary, the median income was lower than
the basic salary in Peru. Although previous research has
found some differences when using indicators such as
the Gini coefficient to measure variables like “income
inequality” [27], or when individual income is measured
through ordinal scales with more than two categories
[28]. It should be noted that the result is not a robust
measure and the confidence intervals of prevalence ratios
were close to the unit. erefore, an extremely care-
ful interpretation is highly suggested and the possibility
of a non-measured confounding effect as a cause of the
results should not be dismissed.
On the other hand, previous evidence has suggested
that the presence of any adverse effect related to ART is
strongly related to a decrease in adherence. For example,
a systematic review developed by Al-Dakkak etal., (2013)
explains that specific adverse events such as fatigue, taste
disturbance, or nausea were significantly related to hav-
ing lesser adherence, in comparison to people who do not
have other types of adverse events [29]. In this research,
data about adverse events were collected in a general
way, without specifications, so it is suggested that future
research develops more detailed instruments in order to
improve the quality of data related to this variable.
Additionally, it is important to consider other factors
that influence the relationship between adverse effects
and adherence, such as the response to access to health
services when these effects occur. Local qualitative
reports suggest that indigenous people who had adverse
effects had a higher probability of abandoning the treat-
ment, due to lack of transportation to reach health
services, lack of medicines and the consequent out-of-
pocket expense to assume treatment of adverse effects,
and lack of health professionals in primary level estab-
lishments. is, added to personal factors such as the
nutritional status of patients and cultural factors such as
the belief that medicines “cause harm,“ generate mistrust
towards health services in these populations [30].
Is important to be highlight that approximately 13%
of participants referred to a disease conceptualization
related to magical or religious origins. Previous qualita-
tive research has found some references, particularly in
awajun groups, about the “disease” (HIV) as a conse-
quence of sorcery (“brujeria”) on some members of the
community [31]. In this context, it is important to clarify
that this sorcery or harm (translated in Spanish as “daño”)
is only one of the numerous terms related to the complex
universe of affection relationships in the awajun cosmo-
vision of disease [32]. For example, previous research
referred to local expressions among Awajun people as “an
unprecedented proliferation of tunchis” (the first mytho-
logical shaman to live at the bottom of the waters), which
makes the evils or harm become something similar to the
symptoms of HIV-AIDS, as a result, they get sick and are
never saved [32]. is could explain some previous find-
ings related to not being afraid of being infected with
HIV by sexual transmission, favoring its spread and pos-
sibly limiting adherence to treatmentf [19].
Likewise, people reported that 18.8% combine ART
with medicinal plants, and 4.4% take only medicinal
plants as a treatment for their disease. Although the con-
sumption of medicinal plants is a common behavior in
chronic patients, especially in people living with HIV
[11, 19], among indigenous people, this could be consid-
ered as a ritual intervention with the use of specific types
of plants (“plantas aliadas”) and mobilization of cosmo-
logical ambits, which permit the restoration of physical
folds and soul (“dietar”) [32].
No association between the other sociocultural fac-
tors and ART adherence was found; however, more than
70% of surveyed people referred to bad family support
and more than 80% referred to stigma and discrimina-
tion in healthcare services because of their disease. It is
well known that people with good family support have
more probabilities of having regularity in medical con-
trols and adherence to antiretroviral treatment [33, 34].
In contrast, qualitative reports referred that many young
Awajun people living with HIV were thrown out of their
houses or have relatives who speak ill of them, which
favors the isolation of affected people [30].
Absence of family members or a partner could be a
factor that decreases resilience to adverse situations,
such as a HIV infection [35]. On the other hand, stigma
and discrimination can be structural and manifested in
institutionalized or social practices, both undermine
availability, access, or use of health services, and pre-
vent people from having a safe and protective family
and community environment [36]. ere is evidence
that people living with HIV and indigenous people,
independently, are victims of stigma and discrimina-
tion in healthcare services [31, 37], but only journalistic
reports suggested that these factors could be determi-
nants of leaving therapy or even hiding their diagnosis
until days before death [30]. Future studies, especially
with mixed methods approach, could be useful in dem-
onstrating possible relationships, independently of this
study’s findings.
ere were no association between clinical features
and ART adherence, but is important to note that almost
20% of surveyed individuals were identified as mem-
bers of risk groups: men who have sex with men (MSM)
(16.8%) and transgender people (1.9%). ese findings
are consistent with previous studies that have reported

Valenzuela‑Oréetal. BMC Public Health (2023) 23:497
a high risk of sexually transmitted diseases or HIV in
indigenous MSM [38]. Additionally, Bartlett etal. (2008)
reported in previous research on four communities from
the same region as the present study that all indigenous
men who tested positive for HIV were from the MSM
risk group, which represents 20% of total individuals liv-
ing with HIV [39].
One limitation of this study is the inability to carry out
a differentiated analysis by ethnicity, due to the small
sample size of Wampis people and “others,“ who typically
define themselves as “descendants of the union between a
Wampis person and an Awajun person.“ Future research
should better define this population group that continues
to identify as part of an “indigenous or native population”
despite being the product of the union between mem-
bers of different communities and analyze their health
problems.
Other limitations include the fact that the question-
naire did not include other components related to the
opinions or attitudes of indigenous people about ART
treatment, regardless of their adherence to it. Laura etal.
(2021) found that there were some cases where ART
treatment boxes were returned to health professionals
so that they could give them to others who needed them
more [30].
It is important to note that the methodological design
of the research does not allow for the establishment of
causal relationships, so future research should evaluate
the true magnitude of the associations found. Addition-
ally, the sample was obtained through a non-probabil-
istic method, so the results cannot be generalized to all
of Peru.
e most significant strength of this research is its
collaborative nature between researchers, regional
health managers, and participating communities, from
planning to execution. is allows for the short-term
implementation of improvements in the ART pro-
gram in these populations and emphasizes the impor-
tance of maintaining a constant intercultural dialogue
between indigenous communities and decision-makers
to quickly detect difficulties that may affect adherence
to treatment.
Conclusion
Only a third of participants reported complete adherence
to antiretroviral therapy. Factors associated with adherence
to antiretroviral medication were related to occupational
status and reporting adverse reactions to the therapeutic
scheme. Interventions aimed at improving adherence in
indigenous people living with HIV should take these fac-
tors into consideration in order to develop effective imple-
mentation strategies.

... INTRODUCTION Active Anti-Retroviral Therapy (HAART) has transformed HIV from a terminal illness to a manageable chronic condition. [22][23][24] Over the past decade, Nigeria has witnessed notable advancements in curbing the HIV/AIDS epidemic. 25,26 The 2019 National AIDS and Reproductive Health Survey (NARHS) demonstrated a substantial reduction in the national HIV prevalence, decreasing from a peak of 5.8% in 2001 to 3.1%. ...

Discrimination and stigma towards those living with HIV/AIDS (PLWHAs) pose serious obstacles to their ability to manage their disease and achieve overall wellbeing. These obstacles make it difficult to receive mental health assistance, prolong social isolation, and impede access to healthcare resources. The purpose of this study is to look into the types, prevalence, and factors that influence stigma and prejudice that PLWHAs in Ikeja, Lagos State, Nigeria, face when they seek antiretroviral therapy (ART). The study also aims to comprehend the ways in which these experiences impact PLWHAs' mental health and ability to receive healthcare. Structured questionnaires were used in this cross-sectional study to gather data from 400 PLWHAs in Ikeja who were undergoing ART. Aspects of stigma such as negative self-image, disclosure concerns, personalized stigma, and public attitudes were all included in the questionnaire. The data were summarized using descriptive statistics, and significant predictors of discrimination and stigma were found using logistic regression analysis. The study also looked at how stigma affects mental health and healthcare access, with an emphasis on identifying important socio-demographic variables that influence these outcomes. The results showed high prevalence of stigma against PLWHAs in Ikeja, in particular, 37.75% of respondents reported they have encountered stigma associated to HIV while seeking healthcare services, and 89.75% of respondents said they were aware of this stigma. Furthermore, 52% of respondents agreed that stigma is exacerbated by the media and societal views, and 45.5% thought that cultural and religious beliefs affected how PLWHAs were treated in their society. Gender, socioeconomic class, and educational attainment were found to be significant predictors of stigma. In addition, 41.5% of respondents experienced unfavorable views from family or friends, and 48.75% of respondents felt ashamed or condemned due to their HIV status. Similarly, 64.25% of PLWHAs said stigma had a major negative impact on their social interactions and mental health, and 65% said stigma made them decide not to disclose their HIV status. While more than a third, 39.75%, of the respondents said that stigma made it difficult for them to get ART and other essential medical services, two-thirds, 67%, stated that the attitudes of healthcare providers influenced their desire to ask for assistance. The study found widespread stigma and prejudice against PLWHAs with a negative influence on mental health and access to healthcare. The study suggests strengthening anti-discrimination laws, holding frequent training sessions for healthcare professionals, improving education and awareness campaigns, and increasing support services for PLWHAs in order to solve these problems. Stakeholders can improve the inclusive and supportive environment for people living with HIV/AIDS by putting these focused actions into practice, which will eventually improve health outcomes and quality of life. These initiatives are essential for reducing HIV/AIDS stigma and advancing a more equitable and compassionate society.

Objetivo: Analisar a adesão aos tratamentos médicos dos pacientes portadores de HIV. Métodos: O artigo foi uma revisão integrativa à literatura com os descritores: Treatment, Adherence e HIV, tendo como resultado 288 artigos no Pubmed e 46 artigos no Scielo, utilizando filtros que selecionam artigos com menos de 5 anos de publicação, Meta-Analysis e Systematic Review. Após a aplicação dos critérios de inclusão e exclusão, 20 artigos foram selecionados para realização desta revisão integrativa à literatura. Resultados: A adesão a TARV em pessoas vivendo com o HIV tem relação direta com o acesso ao serviço de saúde, de modo que variáveis como renda, escolaridade, morar em ambiente rural, dificuldade de transporte, estigma social, comprometem o acesso e, consequentemente, reduzem a taxa de adesão. Além disso, variáveis psicológicas como maior resiliência e percepção menos ameaçadora da doença estão relacionadas a uma maior taxa de adesão. Considerações finais: Pode se considerar que existe uma necessidade de acesso à saúde aos pacientes em situação de vulnerabilidade social, para o combate às possíveis barreiras psicossociais enfrentadas pelas pessoas que vivem com o HIV com foco de alcançar uma adesão adequada ao tratamento. Palavras-chave: HIV, Tratamentos, Adesão. ABSTRACT Objective: To analyze the adherence to medical treatments of patients with HIV. Methods: The article was a integrative literature review with the descriptors: Treatment, Adherence and HIV, resulting in 288 articles in Pubmed and 46 articles in Scielo, using filters that select articles with less than 5 years of publication, Meta-Analysis and Systematic Review. After applying the inclusion and exclusion criteria, 20 articles were selected for this integrative review of the literature. Results: Adherence to ART in people living with HIV is directly related to access to the health service, so that variables such as income, education, living in a rural environment, difficulty in transportation, social stigma, compromise access and consequently, reduce the rate of adhesion. In addition, psychological variables such as greater resilience and less threatening perception of the disease are related to a higher rate of adherence. Final considerations: It can be considered that, there is a need for access to healthcare for patients in situations of social vulnerability, to combat possible psychosocial barriers faced by people living with HIV with a focus on achieving adequate adherence to treatment.

Objetivo: Analisar e sintetizar os fatores relacionados à adesão da terapia antirretroviral (TARV) em portadores de HIV/AIDS no Brasil e as suas principais barreiras de continuidade. Metodologia: Revisão integrativa de literatura utilizando as bases de dados Scientific Eletronic Library Online (SciELO), PUBMED e Literatura Latino-Americana e do Caribe (LILACS) a partir da combinação dos Descritores em Ciências da Saúde (DeCS/MeSH). Resultados: A TARV representa a principal forma de controle da infecção pelo HIV, tornando sua adesão um processo complexo e multifatorial. Os primeiros seis meses de tratamento são determinantes no sucesso da aderência das medicações. Entretanto, a regularidade do uso da TARV perpassa por diversas condições, como: contexto social, renda, escolaridade, efeitos adversos, estigma, uso de álcool e outras drogas, além de rede de apoio e receptividade no sistema de saúde. Por isso, para que haja uma continuidade do processo terapêutico, faz-se imprescindível o acolhimento efetivo e identificação das demandas dos usuários no serviço de saúde, para que esses se sintam seguros e incentivados a permanecer em tratamento. Conclusão: Segundo o levantamento realizado, percebeu-se uma fragilidade na adesão à TARV, o que chama a atenção para medidas de intervenção, tais como: entrevista motivacional, uso de aplicativos móveis, SMS e chamadas telefônicas, contribuindo para a prática assistencial e o acompanhamento integral em saúde desses indivíduos.

We characterized the prevalence of, and estimated associations between, (1) HIV-related healthcare stigma/discrimination and (2) unmet social, mental, and chronic condition healthcare needs among persons living with HIV (PLHIV) in England and Wales. We used data from Positive Voices 2017, a national, cross-sectional probability survey of persons living with HIV (PLHIV) in England and Wales, in which N=3,475 PLHIV provided complete data on demographic characteristics (control variables; age, ethnicity, gender, sexual identity), HIV-related healthcare stigma/discrimination (exposures; treated differently from other patients, care was refused/delayed, worried about being treated differently, avoided seeking needed care, all due to HIV status), and unmet needs (outcomes; unmet peer support, psychological care, management of chronic health conditions, and isolation help needs). Modified Poisson regression models with log links and robust variance estimators were used to produce prevalence ratios and 95% confidence intervals for unadjusted and adjusted associations between demographic characteristics, HIV-related healthcare stigma/discrimination (individual items and total scale score), and unmet needs variables. Two in five participants (40%) endorsed at least one HIV-related healthcare stigma/discrimination item; and 474 (14%), 428 (12%), 459 (13%), and 501 (14%) reported an unmet peer support, psychological care, chronic health condition management, and isolation help need, respectively. Each HIV-related healthcare stigma/discrimination item and the summed scale score were significantly, positively associated with all four unmet needs variables in unadjusted and adjusted models. Trainings for all healthcare workers in HIV-competent, non-stigmatizing care, as well as the development of engagement and delivery approaches for psychosocial care for PLHIV, are needed.

Este artículo presenta una aproximación a los modelos explicativos sobre el VIH/SIDA que circulan entre la población awajún de comunidades que han sido intervenidas por el Fondo Global en el marco de la estrategia contra el VIH. En ese sentido, se entiende la salud como una instancia de interrelación entre el pueblo y el Estado, y por lo tanto, se tiene en cuenta que los diálogos o encuentros médicos, donde se habla de la enfermedad, son determinantes en la experiencia de la enfermedad, pues reflejan un marco de relaciones sociales determinadas histórica y políticamente. Para ello se ha realizado trabajo de campo en el mes de febrero, agosto y setiembre del 2017 en comunidades nativas de la etnia Awajún en el río Cenepa, en Amazonas. A través de la observación constante y participante, y entrevistas abiertas y a profundidad se ha investigado cómo circula y se negocia la información con respecto al VIH/SIDA desde los distintos actores involucrados en la lucha contra el VIH, cómo el contexto sociopolítico afecta los modelos explicativos y cómo expresan su relación con el Estado. Las diversas percepciones y casos recogidos manifiestan modelos de conspiración sobre el ingreso del virus a la zona y modelos de daño y brujería, cuestionando la existencia de la enfermedad y el potencial beneficio del tratamiento. En ese sentido, se vinculan a la relación entre esta población, el Estado y el sistema de salud; así como con condiciones de pobreza y desigualdad; que llevan a la constante negociación y reinterpretación de modelos explicativos en el marco de esta estrategia.

Background The adherence biomarker tenofovir diphosphate (TFV-DP) in dried blood spots (DBS) is associated with viral suppression and predicts future viremia. However, its association with social determinants of health (SDoH) in people with HIV (PWH) remains unknown. Methods DBS for TFV-DP were longitudinally collected from a clinical cohort of PWH receiving tenofovir disoproxil fumarate (TDF)-based therapy (up to 3 visits over 48-weeks) residing in five Colorado counties. To assign SDoH, zip codes at enrollment were matched with SDoH data from AIDSVu (https://aidsvu.org/). SDoH included household income, percent living in poverty, education level and income inequality (quantified using Gini coefficient, where 0 and 1 represent perfect income equality and inequality, respectively). Log-transformed TFV-DP concentrations were analyzed using a mixed-effects model to estimate percent change [95% CI] in TFV-DP for every significant change in the SDoH and adjusted for relevant covariates including age, gender, race, eGFR, BMI, hematocrit, CD4 + T-cell count, antiretroviral drug class and three-month self-reported adherence. Results Data from 430 PWH totaling 950 person-visits were analyzed. In an adjusted analysis, income inequality was inversely associated with TFV-DP in DBS. For every 0.1 increase in the Gini coefficient, TFV-DP concentrations decreased by 9.2% [-0.5, -17.1; P=0.039]. This remained significant after adjusting for HIV viral suppression, where a 0.1 increase in Gini was associated with a decrease of 8.7% [-0.3, -17.9; P=0.042] in TFV-DP. Conclusions Higher income inequality was associated with lower cumulative antiretroviral adherence. These findings support the need for further research on how SDoH impact adherence and clinical care.

Desde el año 2002, de acuerdo con los relatos de algunas familias awajún, empezarona correr los rumores sobre una nueva enfermedad llamada «sida» en el distrito de El Cenepa. Esta condición de origen apách o no indígena se incorporó en la cotidianidad de la población awajún como parte de sus experiencias de enfermedad (jata) y brujería (waweamu), generando las nociones de «jata sida» y “waweamu con síntoma de sida”. La mayoría de los estudios sobre VIH/sida en pueblos indígenas suelen abordar esta condición desde enfoques biomédicos o epidemiológicos. Este artículo presenta otras dimensiones posibles para pensar el VIH/sida en contextos indígenas. Partiendo del complejo conocimiento awajún sobre el cuerpo amazónico y las fuerzas que lo afectan, este artículo busca entender las nociones y experiencias de «enfermedad» y «brujería» que la población awajún usa al hablar de VIH/sida.

Background Acquired Immunodeficiency Syndrome (AIDS) is a major public health problem. Recently AIDS was considered as a manageable chronic disease. High adherence to Anti-Retroviral Therapy (ART) is necessary to achieve undetectable viral load, reduce morbidity, mortality and to improve the quality of life. It is also preventing the drug resistance, reducing the transmission and finally leading to live longer and healthier. Objectives To assess the factor associated with ART adherence among people living with HIV/AIDS (PLWHA) at Wangaya Hospital, in Denpasar, Bali, Indonesia. Methodology A cross-sectional study was carried out during January 2015–December 2017 among 202 PLWHA taking ART for at least 6 months. The participants were interviewed using a semi-structured questionnaire to obtain data on socio-demographic characteristics. The data were analyzed using SPSS software for windows version 24.0. Chi-square test was done, the precision value of 95% (p<0.05) was considered statistically to be significant. Results A total of 202 PLWHA taking ART, 170 (84.16%) were reported with high adherence (≥95%), 32 (15.84%) were low adherence (<95%). Factors found to be independently associated with high adherence to ART were employment status/occupation (p = 0.011), type of ARV (due to adverse effect of ART) (p = 0.002) and family support (p < 0.001). Conclusion This study found that the factor associated with ART adherence among PLWHA who visited Wangaya Hospital, in Denpasar, Bali, Indonesia, was employment status, type of ARV and family support.

Objective: To describe the epidemiological aspects of HIV infection and AIDS among indigenous peoples of the state of Mato Grosso do Sul, Brazil. Methods: This is a descriptive epidemiological study on the occurrence and distribution of HIV infection and AIDS in the indigenous population assisted by the Distrito Sanitário Especial Indígena (Indigenous Special Health District) Mato Grosso do Sul between 2001 and 2014, based on three secondary databases. Annual rates of HIV and AIDS detection and prevalence were calculated, considering case distribution according to village, Health Base Pole and sociodemographic variables. Accumulated rates of detection, mortality and case fatality were calculated by ethnic group and for the Health Base Pole with the highest number of cases. Results: The HIV detection rate fluctuated between 0.0 and 18.0/100 thousand people in the study period. For AIDS, there was no notification before 2007, but in 2012 its rate reached 16.6/100 thousand. HIV prevalence grew between 2001 and 2011, and it continuously grew for AIDS starting from 2007. The highest HIV detection rates occurred among Guarani peoples (167.1/100 thousand) and for AIDS, among the Kaiowá peoples (79.3/100 thousand); mortality and fatality rates were higher among the Kaiowá. Regarding the Dourados Health Base Pole, the AIDS detection rate increased, and the mortality and fatality rates decreased. Conclusions: HIV infection and AIDS have been increasing among indigenous peoples, with distribution of the disease mainly in the Health Base Poles of the southern region of the state, where greater economic and social vulnerability are also observed. The endemic character of HIV and AIDS can become epidemic in some years given the existence of cases in other villages in the state. Its occurrence among the Guarani and Kaiowá populations indicates the need for expanded diagnosis, access to treatment and prevention measures.

Background Indonesia is one of Asia’s countries with the fastest growing rate of human immunodeficiency virus (HIV) infections according to the World Health Organization (WHO). The prevalence of HIV infections in the province of Papua is 2.4% which is 24 times higher than the national rate in Indonesia. This study aimed to investigate the association between stigma, beliefs about medicines, sociodemographic characteristics including ethnicity and adherence in People living with HIV (PLHIV) in Papua, Indonesia. Methods We conducted a cross-sectional study using questionnaires. We included participants from two hospital-outpatient clinics who were on antiretroviral treatment (ART) for more than 6 months, were at least 18 years old, and signed informed consent. Participants completed the Medication Adherence Rating Scale (MARS), Beliefs about Medicines Questionnaire (BMQ), an HIV stigma scale and questions on demographic information. Data on antiretroviral medications were collected from medical records. The outcome was self-reported adherence as measured by the MARS using an 80% cut-off score. Multivariate logistic regression was used to analyse the data. Results Overall, 331 out of 363 eligible participants were included with a mean age of 33.3 (± 9.4) years, 61.6% were female, 67.1% were Papuan. A total of 65.9% of participants were adherent. Being Papuan decreased the likelihood of adherence (odds ratio (OR) = 0.53; 95% confidence interval (CI) = 0.32–0.89). Feeling more distant, a stigma type, also decreased the likelihood of adherence (OR = 0.93; 95% CI = 0.88–0.99). Conclusion The ethnicity of being Papuan and taking a distance to others were associated with non–adherence. Targeted interventions should be developed to improve adherence in this group.

Indigenous leaders remain concerned that systemic oppression and culturally unsafe care impede Indigenous peoples living with HIV from accessing health services that make up the HIV cascade of care. We conducted a systematic review to assess the evidence related to experiences of the HIV care cascade among Indigenous peoples in Australia, Canada, New Zealand, and United States. We identified 93 qualitative and quantitative articles published between 1996 and 2017 reporting primary data on cascade outcomes disaggregated by Indigenous identity. Twelve involved data from Australia, 52 from Canada, 3 from New Zealand and 26 from United States. The majority dealt with HIV testing/diagnosis (50). Relatively few addressed post-diagnosis experiences: linkage (14); retention (20); treatment initiation (21); adherence (23); and viral suppression (24). With the HIV cascade of care increasingly the focus of global, national, and local HIV agendas, it is critical that culturally-safe care for Indigenous peoples is available at all stages.

The aim of this study was to identify sociodemographic factors associated with attrition in the 3 steps of the HIV continuum of care related to the 90-90-90 targets – access to diagnosis, treatment initiation, and virologic suppression, in Brazilian adults (15 years or older), in 2016. Programmatic data were obtained from 2 information systems from the Brazilian Ministry of Health, which register all antiretroviral therapy (ART) dispensations and all CD4⁺ and viral load counts (VL) performed within the country's public health system. The 3 attrition indicators were late presentation to care, defined as a first CD4 count <350 cells/mm³ among ART-naive individuals who performed a first CD4⁺ count in 2016; not being on ART, defined as having no recorded dispensation within the last 100 days of the year, among those who were linked to care in 2016; and not being virologically suppressed, defined as having the last recorded VL >200 copies/mL in 2016, among those with a recorded VL count who were on treatment for at least 6 months. Association of sociodemographic factors with these indicators was analyzed by unconditional logistic regression analysis. Lower educational level and black/brown/indigenous race/color were associated with worse outcomes in the 3 indicators. Environmental indicators, namely the region, size, and social vulnerability index of the municipality of residence, also played an important role in the models. Younger age was strongly associated with not being on ART and not showing virological suppression. Our findings help identify the barriers in the different stages of the HIV continuum of care, which need to be addressed in order to progress toward the achievement of the 90-90-90 targets.

Objectives: To identify the barriers that limit compliance with the prevention of mother-to-child transmission (PMTCT) of HIV measures in two indigenous communities of the Amazon region of Peru. Materials and methods: Qualitative study with a phenomenological approach. Semi-structured interviews were conducted with pregnant women and mothers of children younger than 1 year of the awajún and wampis indigenous communities diagnosed with HIV in the period 2014-2015. Results: The study sample included 15 of 29 eligible women and 87% were Awajún. Limitations and possible negative effects were observed in cases in which sanitary measures for PMTCT were imposed. Considering their knowledge of diseases, including the presence of symptoms and disabilities, many women from these communities do not believe they are infected with HIV and consider the diagnosis a lie or relate the diagnosis to harm, and these beliefs limit their compliance with medical indications and decrease their trust in health services. In addition, the women believe that their children will inevitably be born sick and will die soon, and thus consider cesarean sections and child care a futile effort. Other factors influencing the successful implementation of PMTCT measures include language barriers, remoteness of health centers, and the fear of judgment and moral condemnation by the local community. Conclusions: PMTCT measures challenge the customs, values, and beliefs of pregnant women and mothers in the Awajún and Wampis indigenous communities, and thus these measures are not understood or accepted, jeopardizing the relationship of the mothers with health personnel. Therefore, cultural factors and interventions appropriate to this population must be better understood.
