    Assessment of an HIV-Prevention Intervention for Couples in Peri-Urban Uganda: Pervasive Challenges to Relationship Quality also Challenge Intervention Effectiveness
    (African Journal of AIDS Research, 2020) Kajubi, Phoebe; Ruark, Allison; Hearst, Norman; Ruteikara, Sam; Green, Edward C.
    Reducing multiple and concurrent partnerships has been identified as a priority in generalised HIV epidemics, yet developing successful interventions to bring about such behaviour change has proven challenging. We offered a three-session intervention aimed to improve couple relationship quality and address HIV risk factors, particularly concurrent sexual partnerships (CSP), in a peri-urban community of Kampala, Uganda. Before launching the intervention, a different group of community members participated in eight single-gender focus group discussions (FGDs) which explored issues of couple relationship quality and satisfaction. Findings from the FGDs guided the intervention. All 162 couples invited to the intervention completed a survey pre- and post-intervention. In FGDs, women and men discussed challenges faced in their relationships, including pervasive dissatisfaction, financial constraints, deception and lack of trust, poor communication, lack of sexual satisfaction, and concurrent sexual partnerships. A difference-in-difference analysis showed no measurable impact of the intervention on relationship quality or sexual risk behaviours over a six-month follow-up among 183 individuals who participated in the intervention, although many stated in response to open-ended questions that they had experienced positive relationship changes. Qualitative findings suggest high demand for couple-focused interventions but also reveal many individual-, couple-, community- and structural-level factors which contribute to women and men seeking concurrent sexual partnerships. More intensive interventions may be needed to overcome these barriers to behaviour change and reduce HIV risk. These findings also raise questions about how to interpret divergent qualitative and quantitative data, a topic which has received little attention in the literature.

    Increasing Condom Use Without Reducing HIV Risk: Results of a Controlled Community Trial in Uganda
    (JAIDS Journal of Acquired Immune Deficiency Syndromes, 2005) Kajubi, Phoebe; Kamya, Moses R.; Kamya, Sarah; Chen, Sanny; McFarland, Willi; Hearst, Norman
    Although consistent condom use is effective in reducing individual risk for HIV infection, the public health impact of condom promotion in a generalized epidemic is less clear. We assess the change in condom uptake and number of sex partners after a condom promotion trial in Kampala, Uganda. Methods: Two similar poor urban communities near Kampala were randomized. One received a condom promotion program that taught condom technical use skills in workshops for men aged 18 to 30 years (n = 297) and encouraged condom use. Men in the control community (n = 201) received a brief informational presentation about AIDS. Participants received coupons redeemable for free condoms from distributors in both communities and completed questionnaires at baseline and 6 months later.

    Opportunistic illnesses in Brazilian children with AIDS: results from two national cohort studies, 1983-2007
    (AIDS Research and Therapy, 2011-07-18) Ramos, Jr. Alberto N.; Matida, Luiza H.; Hearst, Norman; Heukelbach, Jorg
    HAART has significantly reduced AIDS-related morbidity in children. However, limited evidence is available from developing countries regarding patterns of opportunistic illnesses. We describe these events and their associated factors in children with AIDS in Brazil. This study is based on two representative retrospective multi-center cohorts including a total 1,859 children with AIDS, infected via mother-to-child transmission (MTCT), between 1983-2002. Opportunistic illnesses were described and analyzed over time. The association of demographic, clinical and operational data with the occurrence of opportunistic diseases was assessed. In total, 1,218 (65.5%) had at least one event of an opportunistic disease. Variables significantly associated with occurrence of these events included: region of residence (OR 2.68-11.33, as compared to the Northern region), age < 1 year at diagnosis (OR 2.56, 95% CI 1.81-3.61, p < 0.001), and non-performance of MTCT prevention measures (OR 1.58, 95% CI 1.21-2.07, p < 0.001). Protective factors included year of HIV diagnosis in the HAART era (OR 0.34, 95% CI 0.15-0.76, p = 0.009) and ART use (OR 0.58, 95% CI 0.44-0.77, p < 0.001). In both periods bacterial infections represented the most common opportunistic events (58.6 vs. 34.7%; p < 0.001), followed by Pneumocystis jirovecii pneumonia (21.9 vs. 13.2%; p < 0.001), and bacterial meningitis/sepsis (16.8 vs. 7.4%; p < 0.001). Despite the significant reduction in recent years, opportunistic illnesses are still common in Brazilian children with AIDS in the HAART era, especially bacterial diseases. The data reinforce the need for scaling up prevention of MTCT, early diagnosis of infection, and improvement of comprehensive pediatric care.

    Prevention messages and AIDS risk behavior in Kampala, Uganda
    (Informa UK Limited, 2011-06-16) Hearst, Norman; Kajubi, Phoebe; Hudes, Esther Sid; Maganda, Albert K.; Green, Edward C.
    Uganda was one of the first countries to substantially reduce HIV rates through behavior change, but these gains have not continued in recent years. Little is known about what messages Ugandans are currently hearing about AIDS prevention, what they themselves believe to be important prevention strategies, and how these beliefs are associated with behavior. We interviewed men and women aged between 20 and 39 in two poor peri-urban areas of Kampala, using a random sample, cross-sectional household survey design. Respondents provided detailed reports of sexual behavior over the past six months, the main prevention message they are currently hearing about AIDS, and their own ranking of the importance of prevention strategies. Condom use was the main AIDS prevention message that respondents reported hearing, followed by getting tested. These were also what respondents themselves considered most important, followed closely by faithfulness. Abstinence was the lowest ranked strategy, but a higher ranking for this prevention strategy was the only one consistently associated with less risky behavior. A higher ranking for condoms was associated with higher levels of risk behavior, while the ranking of testing made no difference in any behavior. These results present challenges for AIDS prevention strategies that rely primarily on promoting condoms and testing. HIV prevention programs need to assess their impact on behavior.
