RESUMO
HIV serodisclosure to sexual partners is an important aspect of HIV prevention, treatment, and care. We investigated the association between partnership duration and serodisclosure among HIV-infected individuals in Lilongwe, Malawi. We analyzed data from a cross-sectional study of individuals attending one of two antiretroviral therapy (ART) clinics in Lilongwe. Clients aged 18-45 years and sexually active within the past six months were eligible. Logistic regression was used to estimate the odds ratio (OR) and 95% confidence interval (CI) for the association between partnership duration ≤1 year and serodisclosure. Five hundred and sixty-two participants completed the survey: 308 (55%) women and 254 (45%) men. Median age was 35 years (IQR 30-40), 90% were married, 88% were on ART, and 95% had serodisclosed to their partner. Marital status, knowledge of partner serostatus, and ART use were significantly associated with serodisclosure. Participants in a relationship for ≤1 year were significantly less likely to disclose their serostatus to their partners compared to those in a relationship for >1 year (OR = 0.18, 95% CI: 0.06, 0.58). Couple-based interventions that encourage serodisclosure among partners within their first year of relationship should be developed to decrease HIV transmission, encourage treatment and support.
