The relation between a number of potential risk factors and change in body mass index per semester was examined in a community-based cohort of 1,809 homosexual and bisexual men seropositive for human immunodeficiency virus type 1 (HIV-1).
The men were followed semiannually for up to 6.5 years between 1984 and 1990.
A total of 9,735 person-semesters of observations were available for analysis.
A Markov-type autoregressive model, adjusting for previous body mass index, was used to predict the change in body mass index over each person-semester.
Overall, the cohort was gaining weight.
An asymptomatic participant 1.8 m in height whose CD4+ cell count was >750/yl gained a mean of 0.5 kg each person-semester.
