Trends and predictors of quality of life among HIV-infected adults taking highly active antiretroviral therapy in rural Uganda

We examined trends and predictors of quality of life (QOL) over 12 months among a prospective cohort of 947 HIV-1-infected adults initiating highly active antiretroviral therapy (HAART) between May 2003 and May 2004 in rural Uganda. Participants provided clinical, demographic and psychosocial data at baseline and every three months thereafter. Outcome measures included physical and mental health summary scores based on the Medical Outcomes Study-HIV Health Survey (MOS-HIV). Generalised estimating equations were used to assess magnitude of change in summary scores and factors associated with QOL. Of 710 women and 237 men enrolled, the mean age was 38.7 years and mean baseline CD4 cell count was 124.1 cells/microL. At enrollment, physical and mental health summary scores were 39.2 and 40, respectively. By 12 months of HAART, scores increased by 11.2 points (p <0.001) and 7.4 points (p <0.001), respectively. For both scores, most gains were achieved by the third month of therapy. While several clinical, psychosocial and sociodemographic factors predicted QOL at HAART initiation, financial dependence on others was the only remaining predictor after controlling for time on HAART. Interventions to enhance the economic and employment opportunities of patients taking HAART in rural Africa may help maximise gains in QOL.
