Abstract

BACKGROUND:: Prior studies found overweight or obese HIV-infected individuals had greater early CD4+ cell recovery on antiretroviral therapy (ART), but the results have been inconsistent. We assessed the longitudinal relationship between body mass index (BMI) and CD4+ cell recovery on ART in a large, multi-site cohort to identify potential physiologic links between adiposity and CD4+ cell expansion. METHODS:: We modeled the relationship of time-updated BMI with CD4+ count in patients starting ART from 17 North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) cohorts. The primary analysis used a linear mixed effects model incorporating up to 13 years of data per patient and adjusted for age, sex, race, ART regimen, baseline CD4+ count and other covariates. Sensitivity analyses limited the cohort to patients with sustained viral suppression or censored at virologic failure. RESULTS:: 14,084 HIV-infected individuals initiating ART contributed data between 1998 and 2010. Time-updated BMI was significantly associated with CD4+ cell recovery over time (p
