Abstract
BACKGROUND
Little is known regarding the long-term effects of antiretroviral (ARV) exposure on body composition for people living with HIV (PLWH) since early childhood. This study explores changes in body fat distribution in relation to ARV exposure.
METHODS
We conducted a prospective study of adults with perinatal HIV (n = 70) using dual-energy X-ray absorptiometry and standard anthropometrics. Trunk to limb fat ratio and waist to hip ratio were compared cross-sectionally to 47 matched controls. Furthermore, changes in body composition and ARV exposure were evaluated longitudinally in a subset of 40 PLWH with a median follow-up of 7 years.
RESULTS
Cross-sectional comparisons of PLWH with controls revealed significantly higher waist to hip ratio, trunk to limb fat ratio, HOMA-IR, and triglycerides, whereas BMI did not differ. Among PLWH with longitudinal follow-up, the prevalence of overweight increased from 27.5% to 52.5% and obesity from 12.5% to 25%; waist to hip and trunk to limb fat ratios also increased (P < 0.0001). Changes in waist to hip ratio were positively correlated with longer exposure during follow-up to darunavir (r = 0.36; P = 0.02), whereas increases in trunk to limb fat ratio were positively correlated with longer exposure to stavudine (r = 0.39; P = 0.01) and didanosine (r = 0.39; P = 0.01) but inversely associated with emtricitabine (r = -0.33; P = 0.04). Increases in waist to hip ratio were correlated with increases in triglyceride levels (r = 0.35; P = 0.03).
CONCLUSION
This study presents strong evidence for persistent and worsening central adiposity in young adults with lifelong HIV and extensive ARV exposure. As this cohort ages, continued evaluation of the body composition and metabolic impact of lifelong ARV therapy is warranted to optimize long-term health.
