Non-disclosure of known HIV-positive status is a barrier to ending HIV as a global health threat as it leads to biased measurements of HIV-treatment coverage indicators and inaccurate estimates of epidemic progress, resulting in wasted resources. Identifying and understanding factors driving non-disclosure among people living with HIV is necessary for encouraging engagement with HIV services and improving treatment coverage, resource allocation, and monitoring of HIV programs in high HIV-burden areas. This analysis assessed factors associated with non-disclosure among survey respondents who had antiretrovirals (ARVs) detected in blood specimens. HIV-positive blood specimens (n = 2,038) from the 2021 Mozambique Population-based HIV Impact Assessment were tested for the presence of ARVs. Weighted prevalence estimates of non-disclosure and select covariates are reported and factors associated with non-disclosure modeled via multivariate logistic regression. Among 1,358 respondents with ARVs detected, 14.1% did not self-report their HIV-positive status during the interview. Adjusting for socio-demographic and clinical factors, non-disclosure was more likely among younger participants aged 15-24 years (adjusted odds ratio [aOR]: 2.15, 95% Confidence Interval [CI] 1.16-4.01) and among those without knowledge of their recent sexual partner's HIV-status (aOR: 2.67, 95%CI: 1.38-5.15). Participants with an unsuppressed viral load were over six times (aOR: 6.27, 95%CI: 2.76-14.23) more likely to not disclose. Improving disclosure rates is vital to obtaining accurate HIV-treatment estimates and assessing epidemic progress. Initiatives prioritizing pre- and post-test counseling, stressing treatment literacy, emphasizing undetectable = untransmittable (U = U) campaigns, and encouraging programs that promote social support may encourage disclosure among individuals living with HIV.

BACKGROUND: Circumcision is a protective measure against sexually transmitted infections (STIs), reducing the risk of HIV infection. This study reported coverage of male circumcision and assessed the factors associated with male uncircumcision in a peri-urban area in Maputo City, Mozambique. METHODS: This cross-sectional study of the Health Demographic Surveillance System in the Polana Caniço neighborhood investigated the sociodemographic and behavioral factors associated with uncircumcised males aged 15-49 y from October 2019 to June 2021. Data were collected from an HIV risk factors questionnaire and descriptive analyses conducted comparing self-reported male circumcision status by sociodemographic factors and sexual behaviors. The association was assessed via χ2 tests, and a multivariable logistic regression model was constructed. Adjusted ORs and 95% CIs were reported for factors associated with uncircumcised status. RESULTS: Of the 3481 males aged 15-49 y who responded to the questionnaire, 79.5% (2766) self-reported being circumcised. The percentage of uncircumcised men steadily increased with age, ranging from 12.4% (95) among males aged 15-19 y to 34.5% (148) of men aged 40-49 y. Men without education or with primary education, as well as those not practicing Islam, were 3-4 times more likely to be uncircumcised. Uncircumcised men were more likely to self-report an STI and a lack of condom use. CONCLUSIONS: Being uncircumcised was associated with not using condoms and having STIs, highlighting the need to further emphasize combination HIV-prevention programs and regular HIV/STI screening. Targeting males with lower education and across religions can help reach those with lower coverage of this effective prevention intervention.
