Incarceration and Sexual Risk Behavior and Incident Sexually Transmitted Infection/HIV in HIV Prevention Trials Network 061: Differences by Study City and Among Black Sexual Minority Men Who Have Sex With Men, Black Sexual Minority Men Who Have Sex With Men and Women, and Black Transgender Women

BACKGROUND

Black sexual minority men (BSMM) and Black transgender women face a disproportionate risk of incarceration and sexually transmitted infection (STI)/HIV, yet research on the longitudinal association between incarceration and STI/HIV risk in these groups is limited.

METHODS

We used data from the HIV Prevention Trials Network (HPTN) 061 study conducted among BSMM and Black transgender women in Atlanta, Boston, Los Angeles, New York City, San Francisco, and Washington, DC, restricting analyses to those who returned for the 6-month follow-up visit when recent incarceration was measured (n = 1169). Using inverse probability of treatment weighting, we measured associations between incarceration and next 6-month multiple partnerships; selling or buying sex; condomless anal intercourse; and incident chlamydia, gonorrhea, syphilis, and HIV. We explored differences by study city, and among BSMM who had sex with men only, BSMM who had sex with men and women, and Black transgender women.

RESULTS

Approximately 14% reported past 6-month incarceration. Incarceration was associated with next 6-month selling sex (adjusted risk ratio [ARR], 1.80; 95% confidence interval [CI], 1.12-2.87) in the overall sample and multiple partnerships among BSMM who had sex with men and women (ARR, 1.34; 95% CI, 1.10-1.63) and transgender women (ARR, 1.77; 95% CI, 1.22-2.57). There is evidence suggesting that incarceration may predict gonorrhea (ARR, 2.35; 95% CI, 0.95-5.77), with particularly strong associations observed in Los Angeles (ARR, 6.48; 95% CI, 1.48-28.38).

CONCLUSIONS

Incarceration may increase STI/HIV risk among BSMM and Black transgender women. Additional mixed-methods research is needed to validate associations and understand pathways.

Perceptions of why Malawians engage in concurrent sexual partnerships among a select population of radio listeners: findings from an exploratory study

Concurrent sexual partnerships have been identified as a potential driver in the HIV epidemic in Southern Africa. This study utilised an innovative approach to explore perceptions of why Malawians may engage in these relationships, and their suggestions for reducing the practice among a select population of radio listeners. Using radio listener feedback in the form of text messages, we analysed approximately 1 000 text messages sent by individuals who listened to a reality radio programme that included real stories, told by Malawians, on topics related to HIV/AIDS. Listeners suggested that lack of satisfaction with one's partner was the overarching reason why individuals had concurrent sexual partnerships. Within the context of lack of satisfaction, listeners cited alcohol use, poor communication and gendered norms as factors related to satisfaction. Listeners suggested that couple communication could increase satisfaction, which, in turn, could reduce concurrent sexual partnerships. Prevention efforts should consider how to utilise couple communication to improve satisfaction as an approach to reduce HIV risk in Southern Africa.

Factors associated with HIV infection among sexually experienced adolescents in Africa: a pooled data analysis

The article examines the factors associated with HIV status among adolescents aged 15-19 years in 13 African countries: Côte d'Ivoire, Democratic Republic of Congo, Guinea, Kenya, Liberia, Mali, Malawi, Rwanda, Sierra Leone, Swaziland, Tanzania, Zambia and Zimbabwe. The data were derived from demographic and health surveys or AIDS indicator surveys conducted between 2004 and 2009. The levels of HIV prevalence among adolescents varied considerably across the countries. There was significantly higher HIV prevalence among female adolescents as compared with their male counterparts. For male adolescents, circumcision was the only variable significantly associated with HIV status. Nonetheless, the data suggest that the association between male circumcision and HIV status may be exaggerated. Indeed, regional-level random effects became insignificant once male circumcision was introduced into the estimated models, indicating a strong correlation between unmeasured regional-level factors and male circumcision. For female adolescents, multiple sexual partnerships, time elapsed since sexual debut, marital status, household wealth, and the regional prevalence of male circumcision were strongly and positively associated with HIV status. Moreover, for female adolescents there appear to be significant unmeasured variables operating at the regional level which influence the levels of HIV infection. The implications of the findings for HIV-prevention programming, policy and research are discussed.

Trends in concurrency, polygyny, and multiple sex partnerships during a decade of declining HIV prevalence in eastern Zimbabwe

Background. Observed declines in the prevalence of human immunodeficiency virus (HIV) infection in Zimbabwe have been attributed to population-level reductions in sexual partnership numbers. However, it remains unknown whether certain types of sex partnerships were more important to this decline. Particular debate surrounds the epidemiologic importance of polygyny (the practice of having multiple wives).

Methods. We analyze changes in reported multiple partnerships, nonmarital concurrency, and polygyny in eastern Zimbabwe during a period of declining HIV prevalence, from 1998 to 2011. Trends are reported for adult men (age, 17–54 years) and women (age, 15–49 years) from 5 survey rounds of the Manicaland HIV/STD Prevention Project, a general-population open cohort study.

Results. At baseline, 34.2% of men reported multiple partnerships, 11.9% reported nonmarital concurrency, and 4.6% reported polygyny. Among women, 4.6% and 1.8% reported multiple partnerships and concurrency, respectively. All 3 partnership indicators declined by similar relative amounts (around 60%–70%) over the period. Polygyny accounted for around 25% of male concurrency. Compared with monogamously married men, polygynous men reported higher levels of subsequent divorce/separation (adjusted relative risk [RR], 2.92; 95% confidence interval [CI], 1.87–4.55) and casual sex partnerships (adjusted RR, 1.63; 95% CI, 1.41–1.88).

Conclusions. No indicator clearly dominated declines in partnerships. Polygyny was surprisingly unstable and, in this population, should not be considered a safe form of concurrency.

Community factors shaping early age at first sex among adolescents in Burkina Faso, Ghana, Malawi, and Uganda

Using data from the National Survey of Adolescents (2004), we examine the community-level factors associated with early age at first sex among adolescents 14-19 years old in four African countries. Regression models are fitted separately by sex for each country for an outcome measuring early age at first sex, with a focus on community-level factors as potential influences of age on sexual debut. The community-level factors associated with adolescents' sexual debut vary widely by both country and gender. Community influences that emerge as risk or protective factors of early sexual debut include community levels of adolescent marriage, wealth, religious group affiliation, sex education, parental monitoring, reproductive health knowledge, media exposure, membership in adolescent social group, and use of alcohol. Results indicate the importance of context-specific understanding of adolescents' sexual behaviour and suggest how elements of place should be harnessed in the development of effective HIV and sexual health interventions.
