A Comparison of Referred Sexual Partners to Their Community Recruited Counterparts in The BROTHERS Project (HPTN 061).

The BROTHERS Project (HPTN 061) was established to determine the feasibility and acceptability of a multi-component intervention among African American MSM to reduce HIV incidence. The goal of this analysis was to determine if the sexual partner referral approach used in HPTN 061 broadened the reach of recruitment with regards to characteristics associated with higher infection rates and barriers to quality health care. Overall, referred sexual partners had notable structural barrier differences in comparison to community-recruited participants: lower income, less education, higher unemployment, HIV positive diagnosis, incarceration history, and no health insurance. The study's findings pose implications for utilizing the sexual partner referral approach in reaching African American MSM who may not be accessed by traditional recruitment methods or who are well-integrated in health care systems.

Swaziland HIV Incidence Measurement Survey (SHIMS): a prospective national cohort study.

BACKGROUND: Swaziland has the highest national HIV prevalence worldwide. The Swaziland HIV Incidence Measurement Survey (SHIMS) provides the first national HIV incidence estimate based on prospectively observed HIV seroconversions. METHODS: A two-stage survey sampling design was used to select a nationally representative sample of men and women aged 18-49 years from 14 891 households in 575 enumeration areas in Swaziland, who underwent household-based counselling and rapid HIV testing during 2011. All individuals aged 18-49 years who resided or had slept in the household the night before and were willing to undergo home-based HIV testing, answer demographic and behavioural questions in English or siSwati, and provide written informed consent were eligible for the study. We performed rapid HIV testing and assessed sociodemographic and behavioural characteristics with use of a questionnaire at baseline and, for HIV-seronegative individuals, 6 months later. We calculated HIV incidence with Poisson regression modelling as events per person-years × 100, and we assessed covariables as predictors with Cox proportional hazards modelling. Survey weighting was applied and all models used survey sampling methods. FINDINGS: Between Dec 10, 2010, and June 25, 2011, 11 897 HIV-seronegative adults were enrolled in SHIMS and 11 232 (94%) were re-tested. Of these, 145 HIV seroconversions were observed, resulting in a weighted HIV incidence of 2·4% (95% CI 2·1-2·8). Incidence was nearly twice as high in women (3·1%; 95% CI 2·6-3·7) as in men (1·7%; 1·3-2·1, p<0·0001). Among men, partner's HIV-positive status (adjusted hazard ratio [aHR] 2·67, 1·06-6·82, p=0·040) or unknown serostatus (aHR 4·64, 2·32-9·27, p<0·0001) in the past 6 months predicted HIV seroconversion. Among women, significant predictors included not being married (aHR 2·90, 1·44-5·84, p=0·0030), having a spouse who lives elsewhere (aHR 2·66, 1·29-5·45, p=0·0078), and having a partner in the past 6 months with unknown HIV status (aHR 2·87, 1·44-5·84, p=0·0030). INTERPRETATION: Swaziland has the highest national HIV incidence in the world. In high-prevalence countries, population-based incidence measures and programmes that further expand HIV testing and support disclosure of HIV status are needed.
