Cardiometabolic risk among HIV-POSITIVE Ugandan adults: prevalence, predictors and effect of long-term antiretroviral therapy.

INTRODUCTION: We investigated the prevalence, predictors of and effect of Antiretroviral Therapy (ART) regimen on cardiometabolic risk among HIV-positive Ugandan adults at enrolment into a prospective cohort to study the Complications of Long-Term ART (CoLTART). METHODS: We collected data on cardiometabolic risk factors including dyslipidemia, hypertension, hyperglycemia, obesity and calculated the mean atherogenic index for Plasma (AIP) and 10 year Framingham risk score (FHS). Exposures were: ART regimen, duration on ART, demographic, socio-economic, behavioral, and life-style factors including smoking, physical activity and diet (including fruit and vegetables consumption). RESULTS: We enrolled 1024 participants, 65% female, mean age was 44.8 years (SD 8.0) and median duration on ART was 9.4 years (IQR 6.1-9.8). The prevalence of abdominal obesity was 52.6%, BMI≥25 kg/m2 -26.1%, hypertension-22.6%, high AIP-31.3% and FHS above 10% was 16.6%. The prevalence of low High Density Lipoprotein (HDL) was 37.5%, high Total cholesterol (Tc)-30.2%, high Low Density Lipoprotein (LDL) -23.6%, high Triglycerides (TG)-21.2%, low physical activity-46.4% and alcohol consumption-26.4%. In multivariate linear regression analyses, increasing age was associated with higher mean Tc, HDL, LDL, FHS (P<0.001) and hyperglycemia (p<0.005). In multivariate logistic regression analyses, Protease Inhibitor (PI) containing regimens were significantly associated with higher risks of abnormal: Tc, LDL, TG, AIP, abdominal obesity, hypertension, low HDL and lower risk of a FHS >10% compared to the non PI regimen. CONCLUSION: ART increases cardiometabolic risk. Integration of routine assessment for cardiometabolic risk factors and preventive interventions into HIV care programs in resource-limited settings is recommended.
