Abstract
OBJECTIVE: To identify the factors associated with HIV self-testing (HIVST) uptake among adolescent men who have sex with men (AMSM) and adolescent transgender women (ATGW) before and during the COVID-19 pandemic. METHODS: A cross-sectional HIVST uptake study was conducted among AMSM and ATGW. Peer educators and health professionals began providing HIVST in February 2019. The outcome was the HIVST uptake before and during the COVID-19 pandemic. The association between each predictor and outcome in each period was analyzed using simple and multiple logistic regressions, estimating odds ratios, and their respective 95% confidence intervals. RESULTS: The uptake was 229/510 (44.9%) and 382/1,075 (35.5%) before and during the pandemic. During the pre-pandemic period, HIVST uptake was higher in participants who reported receptive anal sex. During the pandemic, uptake was lower in participants with a steady sexual partner and higher in those with frequent oral sex with a steady partner in the previous three months. Before and during the pandemic, HIVST uptake was lower in ATGW and higher in those aged 18-19 years and in participants who lived alone. CONCLUSIONS: Uptake decreased during the pandemic. Sexual behavioral factors associated with HIVST uptake changed during the COVID-19 pandemic, showing the fluid dynamics of sexuality in AMSM and ATGW during this period. HIV programs can optimize the implementation of HIVST among adolescents and young people by incorporating effective and differentiated service delivery models to increase HIV testing uptake and to reach undiagnosed individuals effectively.
