    Alcohol use and unprotected sex among HIV-infected Ugandan adults: Findings from an event-level study
    (Archives of sexual behavior, 2018) Woolf-King, Sarah E.; Fatch, Robin; Cheng, Debbie M.; Muyindike, Winnie; Ngabirano, Christine; Kekibiina, Allen; Emenyonu, Nneka; Hahn, Judith A.
    While alcohol is a known risk factor for HIV infection in sub-Saharan Africa (SSA), studies designed to investigate the temporal relationship between alcohol use and unprotected sex are lacking. The purpose of this study was to determine if alcohol used at the time of a sexual event is associated with unprotected sex at that same event. Data for this study were collected as part of two longitudinal studies of HIV-infected Ugandan adults. A structured questionnaire was administered at regularly scheduled cohort study visits in order to assess the circumstances (e.g., alcohol use, partner-type) of the Most Recent Sexual Event (MRSE). Generalized estimating equation (GEE) logistic regression models were used to examine the association between alcohol use (by the participant, the sexual partner, or both the participant and the partner) and the odds of unprotected sex at the sexual event while controlling for participant gender, age, months since HIV diagnosis, unhealthy alcohol use in the prior 3 months, partner-type, and HIV status of partner. A total of 627 sexually active participants (57% women) reported 1,817 sexual events. Of these events, 19% involved alcohol use and 53% were unprotected. Alcohol use by one’s sexual partner (aOR) = 1.70; 95%CI = 1.14, 2.54) or by both partners (aOR: 1.78; 95%CI: 1.07, 2.98), during the MRSE significantly increased the odds of unprotected sex at that same event. These results add to the growing event-level literature in SSA and support a temporal association between alcohol used prior to a sexual event, and subsequent unprotected sex.

    Assessing the Interaction between Depressive Symptoms and Alcohol Use Prior to Antiretroviral Therapy on Viral Suppression among People Living with HIV in Rural Uganda
    (AIDS care, 2020) Foley, Jacklyn D.; Sheinfil, Alan; Woolf-King, Sarah E.; Fatch, Robin; Emenyonu, Nneka I.; Muyindike, Winnie R.; Kekibiina, Allen; Ngabirano, Christine; Samet, Jeffrey H.; Cheng, Debbie M.; Hahn, Judith A.
    Although there is evidence of individual associations between depressive symptoms and hazardous alcohol use with suboptimal antiretroviral therapy (ART) adherence among people living with HIV (PLWH), few studies have established how the two risk factors may interact to predict viral suppression. We conducted secondary data analyses with two cohorts of Ugandan PLWH (N = 657) to investigate the hypothesized interaction between depressive symptoms (Center for Epidemiological Studies Depression Scale) and hazardous alcohol use (Alcohol Use Disorder Identification Test – Consumption and/or Phosphatidylethanol biomarker) prior to ART initiation with viral suppression (<550 copies/ml). We were unable to detect an interaction between depressive symptoms and hazardous alcohol use prior to ART initiation with viral suppression in the first two years (M = 19.9 months) after ART initiation (p = 0.75). There was also no evidence of a main effect association for depressive symptoms (Adjusted Odds Ratio [AOR] = 0.88, 95% Confidence Interval [CI]: 0.50, 1.55) or hazardous alcohol use (AOR = 1.37, 95% CI: 0.80, 2.33). PLWH with depressive symptoms and/or hazardous alcohol use appear to exhibit similar levels of viral suppression as others in care; further work is needed to determine effects on HIV testing and treatment engagement.

    Participant perspectives on incentives for TB preventative therapy adherence and reduced alcohol use: A qualitative study
    (Public Library of Science, 2024-04) Appa, Ayesha; Miller, Amanda P; Fatch, Robin; Kekibiina, Allen; Beesiga, Brian; Adong, Julian; Emenyonu, Nneka; Marson, Kara; Getahun, Monica; Kamya, Moses; Muyindike, Winnie; McDonell, Michael; Thirumurthy, Harsha; Hahn, Judith A; Chamie, Gabriel; Camlin, Carol S
    Economic incentives to promote health behavior change are highly efficacious for substance use disorders as well as increased medication adherence. Knowledge about participants’ experiences with and perceptions of incentives is needed to understand their mechanisms of action and optimize future incentive-based interventions. The Drinkers’ Intervention to Prevent Tuberculosis (DIPT) trial enrolled people with HIV (PWH) in Uganda with latent tuberculosis and unhealthy alcohol use in a 2x2 factorial trial that incentivized recent alcohol abstinence and isoniazid (INH) adherence on monthly urine testing while on INH preventive therapy. We interviewed 32 DIPT study participants across trial arms to explore their perspectives on this intervention. Participants described 1) satisfaction with incentives of sufficient size that allowed them to purchase items that improved their quality of life, 2) multiple ways in which incentives were motivating, from gamification of “winning” through support of pre-existing desire to improve health to suggesting variable effects of extrinsic and intrinsic motivation, and 3) finding value in learning results of increased clinical monitoring. To build effective incentive programs to support both reduced substance use and increased antimicrobial adherence, we recommend carefully selecting incentive magnitude as well as harnessing both intrinsic motivation to improve health and extrinsic reward of target behavior. In addition to these participant-described strengths, incorporating results of clinical monitoring related to the incentive program that provide participants more information about their health may also contribute to health-related empowerment.
