A cohort of 246 women [36.5% of whom were HIV positive
(HIV+) and were receiving ART] were followed to 12 mo
postpartum. Repeated measures included weight, fat mass, fat-free mass, mid upper arm circumference, triceps skin fold thickness [which allowed for the derivation of arm muscle area (AMA) and arm fat area (AFA)], breastfeeding, and individual food insecurity. Longitudinal regression models were constructed to assess associations between HIV and food insecurity and changes in body composition over time.
