Household transport ownership and HIV viral suppression in rural Uganda: a cross- sectional, population-based study

Empirical data on transportation access and HIV treatment outcomes in sub-Saharan Africa are rare. We assessed the association between household transport ownership and HIV viral suppression in rural Uganda.

The study was conducted among people living with HIV aged 15-49 years using cross-sectional data from the Rakai Community Cohort Study (RCCS), collected from June 14, 2018, to November 6, 2020. Transport ownership was defined as household possession of a car, motorcycle, or bicycle. HIV viral suppression was defined as < 1000 HIV RNA copies/ml. Poisson regression with robust variance estimation identified unadjusted and adjusted prevalence ratios and 95% confidence intervals (CI) of HIV viral suppression by transport ownership.

The study included 3,060 persons aged 15-49 living with HIV. Overall HIV viral suppression was 86.5% and was higher among women compared to men (89.3% versus 81.6%; adjusted prevalence ratio: 1.14, 95% CI: 1.10, 1.18). A total of 874 participants (28.6%) resided in households that owned at least one means of transport. HIV viral suppression was 79.8% among men and 88.2% among women from households without any means of transport, compared to 85.4% among men and 92.4% among women from households with at least one means of transport. Adjusted prevalence ratios of HIV viral suppression were 1.11 (95% CI: 1.04, 1.18) for males and 1.06 (95% CI: 1.03, 1.10) for females from households owning at least one means of transport compared with those from households with none.

There was increased HIV viral suppression among people living with HIV from households with transport means compared to those from households without transport means, suggesting transport may facilitate access to, and continued engagement with, HIV treatment services.
