Background: Young women and Lesbian, Gay, Bisexual, Trans, Non-binary/no gender, or Questioning (LGBTQ+) youth in South Africa face some of the highest global levels of intimate partner violence (IPV). Given limited evidence in the wake of the COVID-19 pandemic, which has fuelled IPV globally, we aimed to describe and compare experiences and perpet...
Article
Community engagement increases community trust of research and improves trial participation. However, there is limited documented appraisal of community engagement practices. Several HIV vaccine efficacy trials have been conducted in South Africa, the country most affected by HIV, predominantly in collaboration with the HIV Vaccine Trials Network (...
Article
Efforts to advance sexual health globally require greater understandings of youth intimate relationship dynamics. Among 38 South African youth (21 women/17 men aged 21-30 from Durban and Soweto) we conducted qualitative cognitive interviews to explore how gender and power intersect to shape intimate relationship dynamics (October 2019-March 2021)....

Vaccination is one of the most effective methods for preventing morbidity and mortality from COVID-19. Vaccine hesitancy has led to a decrease in vaccine uptake; driven by misinformation, fear, and perceptions of vaccine safety. Whole inactivated vaccines have been used in one-fifth of the vaccine recipients in Africa, however there is limited real...

Introduction: Sub-Saharan Africa (SSA) carries the burden of the HIV epidemic, especially among adolescents and young people (AYP). Little is known about pre-exposure prophylaxis (PrEP) uptake and preferences among AYP in SSA. We describe preferences for daily and on-demand PrEP among AYP in South Africa, Uganda and Zimbabwe. Methods: A cross-se...

Adolescent girls and young women (AGYW) living with HIV have poor antiretroviral therapy (ART) outcomes. We examined the relationship between psychosocial factors with knowledge of HIV-positive status and antiretroviral therapy exposure among AGYW living with HIV in South Africa. Participants 15-24 years responded to a survey including socio-demogr...

Background Gender inequity and the subsequent health impacts disproportionately affect communities in the Global South. However, most gender equity measures, such as Pulerwitz’ (2000) Sexual Relationship Power Scale (SRPS), are developed and validated in the Global North and then applied in Global South settings without investigation of context app...

Despite sufficient supply, <25% of the population in sub-Saharan Africa has received at least one dose of COVID-19 vaccine. Vaccine mandates have previously been effective in increasing vaccine uptake. Attitudes to COVID-19 vaccine mandates and vaccines for children in African populations are not well understood. We surveyed late-adopters presentin...

Background It is not known whether post-traumatic stress disorder (PTSD) increases HIV-risk behaviours among young people in sub-Saharan Africa. We assessed associations of PTSD symptoms with sexual behaviour, HIV risk perception, and attitudes towards PrEP among young people taking part in the CHAPS community survey. We hypothesised that PTSD symp...

Background The rapid development of vaccines in response to the COVID-19 pandemic has provided an effective tool for the management of COVID-19. However, in Africa there has been a poor uptake of COVID-19 vaccines with only 15% vaccine coverage compared to the WHO global target of 70%. One of the important drivers has been vaccine hesitancy, unders...

Pre-exposure prophylaxis (PrEP) is an HIV-prevention strategy recommended for those at high-risk of infection, including adolescents and young people (AYP). We explored how PrEP roll-out could influence sexual risk behaviour among AYP in East and southern Africa. Twenty-four group discussions and 60 in-depth interviews were conducted with AYP betwe...

Background In contexts where poverty and mental health stressors already interact to negatively impact the most vulnerable populations, COVID-19 is likely to have worsened these impacts. Before the COVID-19 pandemic, adolescent girls and young women (AGYW) in South Africa already faced intersecting mental health stressors and vulnerabilities. It is...

Aim: This study surveyed sexual risk behavior among youth in Soweto, South Africa during the COVID-19 pandemic national lockdown in 2020. Methods: We c...

Some people with HIV (PWH) test positive multiple times without initiating antiretroviral therapy (ART). We surveyed 496 ART-eligible PWH following routine HIV testing at three clinics in Soweto and Gugulethu, South Africa in 2014–2015. Among repeat positive testers (RPTs) in this cohort, we compared rates of treatment initiation by prior treatment...

... Codes were summarized as a team and emerging themes were presented to several audiences to receive peer-review feedback and gain greater insight into the implications and interpretations of the data across multiple global contexts. This included a student group in Canada, a South Africanbased research group comprised of students and faculty interested in gender equity and health, as well as an adolescent community advisory board (ACAB) in Soweto at the PHRU (Closson et al., 2021a;Closson et al., 2021b). The ACAB, established in 2006, is comprised of solely youth representatives aged 17-24, and is responsible for evaluating the impact of the PHRU's adolescent research studies on local community and serving as a voice for both the community and study participants. ...
... However, the COVID-19 pandemic has likely exacerbated FI, making the findings in this study more concerning. Research has highlighted the interactions between FI, HIV, and COVID-19 on multiple levels impacting HIV care outcomes, mental health, and other important public health priorities [16,[94][95][96][97][98][99][100][101][102][103][104][105]. In addition, there have been reports of increases in substance use during the pandemic [106][107][108]. ...
... Within high-risk groups, men who have sex with men (MSM) have the highest prevalence, at least 20 times higher than the general population (Stuardo, 2017;Diaz et al., 2019;Kabapy et al., 2020). The main way of HIV transmission is sexual risk behaviors (SRB) (Martinez et al., 2016;Luz et al., 2019;Coelho et al., 2021;Mulaudzi et al., 2022;Wei et al., 2022). Understood as sexual situations or practices that generate harm to one's or others' sexual health, for example, (1) sexual activity with multiple partners (Sönmez et al., 2021;Dong et al., 2022), (2) absence or misuse of condoms (Closson et al., 2018;Chu and Huang, 2020), (3) sexual activity under the influence of alcohol and drugs (Palfai and Luehring-Jones, 2021;Bustamante et al., 2022). ...
... Using self-reported status (if feasible) could also reduce retesting, a common phenomenon among already-diagnosed PWH across sub-Saharan Africa [30], and more readily link PWH to treatment. While repeat testing among diagnosed PWH was prevalent [30][31][32] prior to the universal test and treat (UTT) era that began in 2015 (at which point, persons testing positive were linked to care immediately, regardless of CD4 count) [33,34], post-UTT evidence shows that retesting among diagnosed PWH persists, including in South Africa [35,36]. ...
