Statistical Methodology for HIV Serodiscordance among Couples: The case of Mozambique

Abstract

Even though several promising global efforts have been made in increasing effective treatment and prevention programs, the number of people living with HIV is still high. Across countries including Mozambique, a substantial proportion of couples with HIV is discordant. Hence the HIV prevalence of serodiscordance among heterosexual couples, who are often in stable partnerships but unaware of both partner's serostatus is high. In this study risk factors associated with serodiscordance among couples in Mozambique was investigated. Cross-sectional data based on a national-representative sample in Mozambique was used. Several statistical models such as ALR and GLMM, BCL and GLMM, ALR, BDM, GLMM were applied. Statistical findings revealed that prevalence, STID, union number and wealth index were risk factor associated HIV serodiscordance in Mozambique. Moreover, men were at higher risk of HIV infection than the women, hence couples were more likely to be male than female discordant. Heterog
