Peer-to-peer chain recruitment has been used for descriptive studies, but few intervention studies have employed it. We used this method to enroll sexually active women ages 18 to 25 into an online Pre-Exposure Prophylaxis (PrEP) information and motivation intervention pilot in eThekwini (Durban), South Africa. Seeds (N = 16) were recruited by study staff and randomized to Masibambane, Ladies Chat, a Gender-Enhanced group-based WhatsApp Workshop (GE), or Individual-Access (IA), a control condition that provided participants with online information/motivation materials only.

Despite expanded antiretroviral therapy (ART) eligibility in South Africa, many people diagnosed with HIV do not initiate ART promptly, yet understanding of the reasons is limited. Using data from an 8-month prospective cohort interview study of women and men newly-diagnosed with HIV in three public-sector primary care clinics in the eThekwini (Durban) region, South Africa, 2010-2014, we examined if theoretically-relevant social-structural, social-cognitive, psychosocial, and health status indicators were associated with time to ART initiation. Of 459 diagnosed, 350 returned to the clinic for their CD4+ test results (linkage); 153 (33.

Female and male condoms are the only methods that prevent both sexually transmitted infections (STIs), including HIV, and unintended pregnancy. Despite continuing high STI rates, few studies investigate factors predicting whether women initiating female condom (FC) use sustain use. Using data from a randomized trial, we examined predictors of sustained FC use at five-month follow-up (FU2) among female university students in South Africa who participated in either a one-session, information-only, group-delivered or a two-session, group-delivered .

Linkage to care following an HIV diagnosis remains an important HIV care continuum milestone, even in the era of universal ART eligibility. In an 8-month prospective cohort study among 459 (309 women, 150 men) newly-diagnosed HIV-positive individuals in three public-sector clinics in Durban metropolitan region, South Africa, from 2010 to 2013, median time to return to clinic for CD4+ results (linkage) was 10.71 weeks (95% CI 8.

Diagnosis and treatment of acute HIV infection (AHI) is crucial for ending the HIV epidemic. Individuals with AHI, who have high viral loads and often are unaware of their infection, are more likely to transmit HIV to others than those with chronic infection. In preparation for an educational intervention on AHI in primary health care settings in high HIV-prevalence areas of New York City, 22 clinic directors, 313 clinic providers, and 220 patients were surveyed on their knowledge and awareness of the topic from 2012-2015.

Few studies have examined HIV-testing decision-making since the South African national HIV counseling and testing campaign in 2010-2011 and subsequent expansion in antiretroviral therapy (ART) eligibility in 2012. We describe HIV-testing decision-making and pathways to testing among participants in Pathways to Care, a cohort study of newly-diagnosed HIV-positive adults in KwaZulu-Natal. Our analysis is embedded within a theoretical framework informed by Arthur Kleinman's work on pluralistic healthcare systems, and the concept of diagnostic itineraries (i.

Background: Timely linkage to care by newly-diagnosed HIV+ individuals remains a significant challenge to achieving UNAIDS 90-90-90 goals. Current World Health Organization (WHO) guidelines recommend initiating anti-retroviral treatment (ART) regardless of CD4+ count, with priority given to those with CD4+ <350 cells/μl. We evaluated the impact of not having a day-of-diagnosis CD4+ count blood draw, as recommended by South African guidelines, on time to linkage, using data from a prospective cohort study.

Unlabelled: This pilot study evaluated a 15 session classroom intervention for HIV and pregnancy prevention among grade 8-10 boys and girls (ages 14-17) in rural South Africa, guided by gender-empowerment theory and implemented by teachers, nurses, and youth peer educators. Pre- and post-intervention surveys included 933 male and female students in two intervention and two comparison schools.

Main Outcome: condom use at last sex; secondary outcomes: partner communication; gender beliefs and values; perceived peer behaviors; self-efficacy for safer sex.

As a 'case-study' to demonstrate an approach to establishing a fertility-intent prediction model, we used data collected from recently diagnosed HIV-positive women (N = 69) and men (N = 55) who reported inconsistent condom use and were enrolled in a sexual and reproductive health intervention in public sector HIV care clinics in Cape Town, South Africa. Three theoretically-driven prediction models showed reasonable sensitivity (0.70-1.

Background: Sexual and reproductive health (SRH) services for HIV-positive women and men often neglect their fertility desires. We examined factors associated with pregnancy intent among recently diagnosed HIV-positive women (N = 106) and men (N = 91) who reported inconsistent condom use and were enrolled in an SRH intervention conducted in public sector HIV care clinics in Cape Town.

Methods: Participants were recruited when receiving their first CD4 results at the clinic.

Relatively few interventions have tested the efficacy of female condom promotion either alone or in combination with other barrier methods. We evaluated the efficacy of a two-session (enhanced) cognitive-behavioral intervention (EI) (n = 147) against a one-session control (minimal) educational intervention (MI) (n = 149) to promote female condom (FC) use among female students aged 18-28 at a South African university. We assessed change from baseline to 2.

We conducted a structural intervention to promote the female condom (FC), comparing 44 agencies randomized to a Minimal Intervention (MI) [developing action plans for promotion and free access] or an Enhanced Intervention (EI) [with the addition of counselor training]. Intervention effects were evaluated via surveys with agency directors, counselors and clients at baseline and 12 months. Agency-level outcomes of the FC did not differ between the two interventions at follow-up.

Young men in South Africa can play a critical role in preventing new human immunodeficiency virus (HIV) infections, yet are seldom targeted for HIV prevention. While reported condom use at last sex has increased considerably among young people, consistent condom use remains a challenge. In this study, 74 male higher education students gave their perspectives on male and female condoms in 10 focus group discussions.

Large-scale internal migration in China may be an important mechanism for the spread of HIV/sexually transmitted infections (STIs) because of the risk behaviours of migrants. We conducted a self-administered survey among 724 employees of a high-end entertainment centre in Kunshan, Jiangsu Province, China. Using logistic regression, we examined the association of hometown of origin (Kunshan city, elsewhere in Jiangsu Province, or another province in China) and consecutive years living in Kunshan with measures of HIV/STI risk behaviour.

Health care providers can play a key role in influencing clients to initiate and maintain use of the female condom, an underused method for HIV/STI and pregnancy prevention. In 2001-2002, based on semistructured interviews with 78 health care providers from four types of settings in New York City, we found that most providers had seen the female condom, but they had not used it and did not propose the method to clients. They lacked details about the method-when to insert it, where it can be obtained, and its cost.

In post-Apartheid South Africa, women are constitutionally guaranteed protections and freedoms that were previously unknown to them. These freedoms may have positive implications for women's ability to negotiate sexual protection with partners and hence prevent unintended pregnancy and decrease their risk of HIV. Among tertiary institution students, who are a relatively 'privileged' group, there is little information on gender norms that might shape responses to HIV-prevention programmes.

As more people are living long-term with HIV there are growing concerns about specific behaviors that can affect both personal and the public health. This study examined the relationship between antiretroviral therapy (ART) adherence and sexual risk behavior and their association with psychosocial and health factors among a diverse sample of 2,849 HIV-infected adults. Only 8.

Unintended pregnancy, HIV and other sexually transmitted infections are major threats to the health of South African youth. Gendered social norms make it difficult for young women to negotiate safer sex, and sexual coercion and violence are prevalent. Sexual activity among adolescents is influenced strongly by conservative social norms, which favour abstinence.

New methods are now available, and others are being developed, that could enable women to take the initiative in preventing sexually transmitted infections. However, attempts to capitalize on "female-controlled" preventive methods thus far have met with limited success. Female-initiated methods were introduced to intervene in the state of gender relations and assist women who are disempowered vis-à-vis their male partners.

As the number of HIV infections in women has increased, there has been a concomitant recognition that prevention efforts to reduce sexual transmission must address the gendered context in which risk behavior occurs. This paper provides a longitudinal perspective on the emergence of the HIV epidemic in U.S.
