Youth living with HIV in sub-Saharan Africa have poor HIV care outcomes. We determined the association of recent significant life-events with HIV antiretroviral treatment (ART) initiation and HIV viral suppression in youth aged 15-24 years living with HIV in rural Kenya and Uganda. This was a cross-sectional analysis of 995 youth enrolled in the SEARCH Youth study. At baseline, providers assessed recent (within 6 months) life-events, defined as changes in schooling/employment, residence, partnerships, sickness, incarceration status, family strife or death, and birth/pregnancy, self-reported alcohol use, being a parent, and HIV-status disclosure. We examined the frequencies of events and their association with ART status and HIV viral suppression (<400 copies/ul). Recent significant life-events were prevalent (57.7%). Having > 2 significant life-events (aOR = 0.61, 95% CI:0.45-0.85) and consuming alcohol (aOR = 0.61, 95% CI:0.43-0.87) were associated with a lower odds of HIV viral suppression, while disclosure of HIV-status to partner (aOR = 2.39, 95% CI:1.6-3.5) or to family (aOR = 1.86, 95% CI:1.3-2.7), being a parent (aOR = 1.8, 95% CI:1.2-2.5), and being single (aOR = 1.6, 95% CI:1.3-2.1) had a higher odds. This suggest that two or more recent life-events and alcohol use are key barriers to ART initiation and achievement of viral suppression among youth living with HIV in rural East Africa.

Rates of Isoniazid Preventive Therapy (IPT) completion remain low in programmatic settings in sub-Saharan Africa. Differentiated HIV care models may improve IPT completion by addressing joint barriers to IPT and HIV treatment. However, the impact of differentiated care on IPT completion remains unknown. In a cross-sectional study of people with HIV on antiretroviral therapy in 5 communities in rural Uganda, we compared IPT completion between patients receiving HIV care via a differentiated care model versus a standard HIV care model and assessed multi-level predictors of IPT completion. A total of 103/144 (72%) patients received differentiated care and 85/161 (53%) received standard care completed IPT ( p < 0.01). Adjusting for age, gender and community, patients receiving differentiated care had higher odds of completing IPT (aOR: 2.6, 95% CI: 1.5-4.5, p < 0.01). Predictors of IPT completion varied by the care model, and differentiated care modified the positive association between treatment completion and the belief in the efficacy of IPT and the negative association with side-effects. Patients receiving a multi-component differentiated care model had a higher odds of IPT completion than standard care, and the model's impact on health beliefs, social support, and perceived side effects to IPT may underlie this positive association.

Expectations about future health and longevity are important determinants of individuals' decisions to invest in physical and human capital. Few population-level studies have measured subjective expectations and examined how they are affected by scale-up of antiretroviral therapy (ART). We assessed these expectations in communities receiving annual HIV testing and universal ART. Longitudinal data on expectations were collected at baseline and one year later in 16 intervention communities participating in the Sustainable East Africa Research in Community Health (SEARCH) trial of the test and treat strategy in Kenya and Uganda (NCT01864603). A random sample of households with and without an HIV-positive adult was selected after baseline HIV testing. Individuals' expectations about survival to 50, 60, 70, and 80 years of age, as well as future health status and economic well-being, were measured using a Likert scale. Primary outcomes were binary variables indicating participants who reported being very likely or almost certain to survive to advanced ages. Logistic regression analyses were used to examine trends in expectations as well as associations with HIV status and viral load for HIV-positive individuals. Data were obtained from 3126 adults at baseline and 3977 adults in year 1, with 2926 adults participating in both waves. HIV-negative adults were more likely to have favorable expectations about survival to 60 years than HIV-positive adults with detectable viral load (adjusted odds ratio [AOR] 1.87, 95% CI 1.53-2.30), as were HIV-positive adults with undetectable viral load (AOR 1.41, 95% CI 1.13-1.77). Favorable expectations about survival to 60 years were more likely for all groups in year 1 compared to baseline (AOR 1.53, 95% CI 1.31-1.77). These findings are consistent with the hypothesis that universal ART leads to improved population-level expectations about future health and well-being. Future research from the SEARCH trial will help determine whether these changes are causally driven by the provision of universal ART.

Our objective was to determine whether serial HIV testing during pregnancy and the postpartum period as well as male partner testing are acceptable and feasible in Tororo, Uganda. This was a prospective study of pregnant women at the Tororo District Hospital (TDH) Antenatal Clinic. Patients presenting for routine antenatal care were asked to participate in a serial HIV testing integrated into standard antenatal and postpartum/child immunization visits, and to invite their male partners for HIV testing. Serial testing was defined as ≥2 tests during pregnancy and ≥2 tests within 24 weeks postpartum. Of the 214 enrolled women, 80 (37%) completed serial testing, 176 (82%) had ≥2 tests, and 147 (69%) had ≥3 tests during the study period. One hundred eighty-two women (85%) accepted male partner testing, but only 19 men (10%) participated. One woman seroconverted during the study, for a cumulative HIV incidence of 0.5% (1/214). In multivariable logistic regression analysis, longer distance between home and clinic (aOR 0.87 [95% CI 0.79-0.97]) and not knowing household income (aOR 0.30 [95% CI 0.11-0.84]) were predictive of not completing serial testing. Higher level of education was associated with completing serial testing (linear trend p value = 0.05). In conclusion, partial serial HIV testing was highly acceptable and feasible, but completion of serial testing and male partner testing had poor uptake.
