Objective
We sought to increase adolescent HIV testing across rural communities in east Africa and identify predictors of undiagnosed HIV.
Design
Hybrid mobile testing.
Methods
We enumerated 116,326 adolescents (10–24 years) in 32 communities of Uganda and Kenya (SEARCH:NCT01864603): 98,694 (85%) reported stable (≥6 months of prior year) residence. In each community we performed hybrid testing: 2- week multi-disease community health campaign (CHC) that included HIV testing, followed by home-based testing of CHC non-participants. We measured adolescent HIV testing coverage and prevalence, and determined predictors of newly-diagnosed HIV among HIV+ adolescents using multivariable logistic regression.
Results
86,421 (88%) stable adolescents tested for HIV; coverage was 86%, 90%, and 88% in early (10–14), mid (15–17) and late (18–24) adolescents, respectively. Self- reported prior testing was 9%, 26%, and 55% in early, mid and late adolescents tested, respectively. HIV prevalence among adolescents tested was 1.6% and 0.6% in Ugandan women and men, and 7.1% and 1.5% in Kenyan women and men, respectively. Prevalence increased in mid-adolescence for women, and late adolescence for men. Among HIV+ adolescents, 58% reported newly-diagnosed HIV. In multivariate analysis of HIV+ adolescents, predictors of newly-diagnosed HIV included male gender (OR=1.97 [95%CI: 1.42–2.73]), Ugandan residence (OR=2.63 [95%CI: 2.08–3.31]), and single status (OR=1.62 [95%CI: 1.23–2.14] vs. married).
Conclusions
The SEARCH hybrid strategy tested 88% of stable adolescents for HIV, a substantial increase over the 28% reporting prior testing. The majority (57%) of HIV+ adolescents were new diagnoses. Mobile HIV testing for adults should be leveraged to reach adolescents for HIV treatment and prevention.
