Introduction. The participation of psychologists in the therapeutic care of people living with HIV (PLWHA) is not clear, since their functions are only focused on accompaniment and not on pharmacological and therapeutic adherence, and care is only provided in case the patient requires it and is not part of the treatment scheme for HIV control. Obj...

Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) are widely recognised as two prevalent sexually transmitted infections that can have detrimental effects on women’s reproductive health. Previous research has concentrated on studying high-risk populations, resulting in limited epidemiological data regarding the general population. Therefore...

The use of telehealth has increased during the last few years due to the COVID-19 pandemic, since all the health systems were forced to limit the services offered to those who sought help, which significantly affected the treatment of every illness that was not related to said sickness (Doraiswamyet al., 2020). This also affected the services provi...

In 2019, Mexico was one of the first countries in Latin America to commit resources to achieve hepatitis C elimination by 2030. One year after this commitment, the global COVID-19 pandemic diverted attention to address immediate health needs to combat the spread of the disease. As a result, efforts to implement hepatitis C prevention and management...

Research increasingly recognizes the importance of social and built environments in shaping health, including risks for and outcomes related to HIV and sexually transmitted infections (STI), but research on sex work venues is limited. We use latent class analysis to identify patterns of sex work venue characteristics and factors associated with cla...

Introduction There is little information in Mexico about the transition to injecting drugs among drug users in cities other than Tijuana. Objective We compare characteristics of the onset of drug use and first injection among people who inject drugs (PWID) from Ciudad Juárez and Hermosillo, two cities of Northern Mexico and identify factors associ...

Background The prevalence of hepatitis C in people who use injectable drugs along the USA–Mexico border is very high (>90%). In 2019, the Mexican government committed to providing hepatitis C treatment with priority for people who use injectable drugs, people living with HIV, and people living in prison or jail, yet the immediate plan for prioritiz...

Background: Understanding the patterns of HIV/AIDS epidemics is crucial to tracking and monitoring the progress of prevention and control efforts in countries. We provide a comprehensive assessment of the levels and trends of HIV/AIDS incidence, prevalence, mortality, and coverage of antiretroviral therapy (ART) for 1980-2017 and forecast these est...

Cross-border infectious disease transmission is a concern related to drug tourism from the U.S. to Mexico. We assessed this risk among people who inject drugs (PWID) in Tijuana, Mexico. We measured the prevalence and identified correlates of injecting with PWID visiting from the U.S. among PWID in Tijuana using univariable and multivariable logisti...

Introduction Needle and syringe programs (NSP) reduce syringe sharing and HIV transmission among people who inject drugs (PWID). However, their effectiveness relies on sufficient individual and population level coverage. In Tijuana, Mexico, the Global Fund (GF) supported NSP during 10/2011-12/2013, but withdrew funds at the end of 2013 following Me...

Introduction. Efforts to identify new cases of HIV, HVC and other STIs, through the application of quick tests, focus on people who inject drugs, without taking into account the fact that the use of alcohol and other drugs of abuse inhibits decision making, increasing the transmission of STIs through risky sexual practices. Accordingly, it is neces...

Sex work around the world takes place under conditions of structural violence and vulnerability. The Mexico-U.S. border region is characterized by the presence of factors that increase the risk for health harms among female sex workers (FSW); located in this context, the risk environments of Tijuana and Ciudad Juárez have similar yet distinct chara...

Injecting-drug use is present in 179 of 206 countries worldwide, with human immunode-�ciency virus (HIV) and hepatitis C virus (HCV) prevalence of 17.8% and 52.3%, respec-tively, among the 15.6 million people who inject drugs (PWIDs) (Degenhardt et al., 2017; Platt et al., 2016). This epidemic produces a high impact on global public health by incre...

Materials and methods: To calculate crude and standardized mortality rates, official figures of deaths from Instituto Nacional de Estadística y Geografía and population estimates from Consejo Nacional de Población were used. Magnitude, di...

Female sex workers (FSWs) experience syndemic factors (e.g., polydrug use, hazardous alcohol consumption, client-perpetrated violence, depression, and sexually transmitted infections) that often heighten vulnerability to HIV and limit healthcare utilization. We hypothesized that syndemic factors will limit FSWs' uptake of pre-exposure prophylaxis (...

In Tijuana, Mexico, sex work is regulated by the municipal health department and includes regular testing for HIV and other sexually transmitted infections (STIs) for registered female sex workers (FSWs). However, Papanicolaou (Pap) testing is missing from current sexual health assessments. We aimed to answer the following research questions: (1) W...

Previous evidence links substance use disorders (SUD) to STI/HIV risk and suggests that comorbid psychiatric disorders increase the probability to engage in sexual risk behaviors. This study had two aims: (1) to identify subgroups based on sexual risk behavior using a person-centered approach in a sample of substance users and (2) to measure the as...

Background: Rapid testing and counseling (RTC) procedures have become a relevant strategy to decrease the health impact of HIV/STIs. It’s known that individuals who use substances have an increased risk for HIV/STIs. In Mexico about a third of the individuals with substance use disorders (SUDs) receive treatment at the Community-Based Residential C...

Objective From 2011 to 2013, the Global Fund (GF) supported needle and syringe programmes in Mexico to prevent transmission of HIV among people who inject drugs.

Abstract Background A large body of research has investigated the rise of injection drug use and HIV transmission in Tijuana and Ciudad Juarez (CJ). However, little is known about the dynamics of injecting in Hermosillo. This study compares drug-related behaviors and risk environment for HIV of people who inject drugs (PWID) across Tijuana, CJ, and...

Introduction and aims: Smoking methamphetamine is associated with increased risk of HIV among female sex workers (FSW). The structural context of substance use is an important shaper of individual behaviour; however, structural determinants of methamphetamine use among FSWs are largely unknown. We identified individual, structural and neighbourhoo...

Abstract Background Mexico’s 2009 “narcomenudeo reform” decriminalized small amounts of drugs, shifting some drug law enforcement to the states and mandating drug treatment diversion instead of incarceration. Data from Tijuana suggested limited implementation of this harm reduction-oriented policy. We studied whether a police education program (PEP...

Background: Policing practices such as syringe confiscation and arrest can act as important social-structural drivers of HIV risk among people who inject drugs (PWID). However, police referral to treatment and other services may improve the health of PWID. Little is known about the role of modifiable attitudinal and knowledge factors in shaping of...

We use data collected from a sample of 400 male clients of female sex workers (FSW) to examine their HIV testing behavior. We present frequencies of HIV testing and used bivariate and multivariable analyses to assess its socio-demographic, behavioral, and psychosocial correlates. We found that the majority (55 %) of male clients of FSW in Tijuana,...

Objective: Migration is a structural factor that increases HIV vulnerability. Acculturative stress represents a possible mechanism through which migration may negatively impact HIV risk. This study investigated socio-ecological factors associated with acculturative stress levels and examined the association between acculturative stress and HIV-rel...

Cross-sectional analysis of 78,624 PLWH treated in 32 Mexican states on January 1, 2017 and registered at the national database ’’SALVAR’’. We estimated annual HAART cost per patient using ARV prices negotiated by the Mexican government and the recorded therapy. Effectiveness was defined as the percent of PLWH with a last viral load < 1000 copies/m...

A retrospective patient’s record analysis was conducted using the database SALVAR of the Ministry of Health. We analyzed PLWH whom initiated HAART between 2010-2016. Patients with undetectable viral loads before the first 2 weeks of treatment were excluded, as well as duplicate records, trans people and children under 10 years at HAART initiation....

Background: Globally, female sex workers (FSWs) have been identified as a high-risk group for human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). However, as women of reproductive age, FSWs also have children. Few studies have investigated if financial responsibilities associated with motherhood increase women's vulnerab...

HIV risk among Mexican migrants varies across migration phases (pre-departure, transit, destination, interception, and return), but there is limited knowledge about specific sexual behaviors, characteristics of sexual partners, and sexual contexts at different migration stages. To fill the gap, we used data from a cross-sectional population-based s...

Men’s misogynistic attitudes (i.e., dislike or contempt for women) have been shown to be associated with men’s perpetration of physical/sexual violence against women and poor health outcomes for women. However, these attitudes have rarely been examined for their influence on men’s own health. This article examines the sociodemographic, substance us...

According to international reports, Mexico has a high prevalence of sexually transmit-ted infections (STIs), such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV). There are approximately 34 million people infected with HIV (National Center for Prevention and Control of HIV-AIDS [CENSIDA], 2011), between 13...
