BackgroundWidespread voluntary medical male circumcision (VMMC) in Africa could avert an estimated 3·436 million HIV infections and 300,000 deaths over the next 10 years. Most Zambian men, however, have expressed little interest in undergoing VMMC. This study tested the effect of an intervention designed to increase demand for VMMC among these “hard to reach” men.MethodsThis cluster randomized controlled trial was conducted from 2012 to 2014 in Lusaka, Zambia (HIV prevalence = 20·8%). 13 Community Health Centers (CHCs) were stratified by HIV voluntary counseling and testing (VCT) rates and patient census and randomly assigned (5:5:3) to Experimental, Control or Observation Only conditions. CHC health care providers at all 13 sites received VMMC training. Trial statisticians did not participate in randomization. 800 uncircumcised HIV-, post-VCT men, 400 per condition, were recruited; female partners were invited to participate. The primary outcome was the likelihood of VMMC by 12 months post-intervention. The trial registration is NCT 01688167.Findings161 participants in the Experimental condition underwent VMMC as compared to 96 Control participants [adjusted odds ratio = 2·45, 95% CI = (1·24, 4·90) p = ·0166]. Post-VMMC condom use among Experimental condition participants increased compared to baseline, with no change among Control participants. No adverse events related to study participation were reported.InterpretationThe Spear and Shield intervention combined with VMMC training was associated with a significant increase in the number of VMMCs performed as well as in condom use among “hard to reach” Zambian men. Results support the importance of comprehensive HIV prevention programs that increase supply of and demand for VMMC services.FundingNIH/NIMH R01MH095539.

This pilot study assessed the determinants of engagement in HIV care among Zambian patients new to antiretroviral (ARV) therapy, and the effect of an intervention to increase medication adherence. Participants (n = 160) were randomized to a 3-month group or individual intervention utilizing a crossover design. Psychophysiological (depression, cognitive functioning, health status), social (social support, disclosure, stigma), and structural (health care access, patient-provider communication) factors and treatment engagement (adherence to clinic visits and medication) were assessed. Participants initially receiving group intervention improved their adherence, but gains were not maintained following crossover to the individual intervention. Increased social support and patient-provider communication and decreased concern about HIV medications predicted increased clinic attendance across both arms. Results suggest that early participation in a group intervention may promote increased adherence among patients new to therapy, but long-term engagement in care may be sustained by both one-on-one and group interventions by health care staff.

Introduction Evidence-based HIV prevention interventions have been translated to a variety of contexts across sub-Saharan Africa. Non-specialized community health center (CHC) staff members have been successfully engaged to deliver the interventions, which can be integrated into pre-existing HIV service programs in community-based health care delivery sites. This manuscript describes the process of implementing the Partner Project, a couples HIV risk reduction intervention, and examines the ability of CHC staff to achieve risk reduction outcomes comparable to those of the highly-trained research staff. Methods The Partner Project was implemented within the HIV Counseling and Testing program in 6 urban community health clinics in Lusaka, Zambia. One hundred ninety seven HIV-seroconcordant and –discordant couples were sequentially enrolled to the control group or to receive the intervention from Partner research or CHC staff members. Couple members completed assessments on condom use, alcohol use, and intimate partner violence (IPV) at baseline, 6, and 12 months follow-up. Results Sexual barrier use outcomes achieved by the CHC staff were comparable to or better than those achieved by the Partner Project research staff, and both were superior to the control group. A reduction in IPV was observed for the entire sample, although no change in alcohol use was observed. Conclusions Implementation of HIV prevention interventions at the community level should take advantage of existing resources available within the CHC staff. This is especially relevant in resource limited settings as consideration of the financial and clinical requirements of intervention programs is essential to the achievement of successful program implementation.
