Partnership duration and HIV serodisclosure among people living with HIV/AIDS in Lilongwe, Malawi.

Abstract

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.
