Abstract

Recent theoretical work suggests that reductions in aggregate measures of risk behaviors are to be expected during a human immunodeficiency virus epidemic, because mortality is likely to be differential with respect to the level of the risk behavior. We present and apply a methodology for quantifying the effects of differential mortality on risk behavior changes in closed cohort studies. We demonstrate that differential mortality has caused 21% of the observed reduction in the mean, 29% of the observed reduction in the effective average, and 33% of the observed reduction in the variance of a risk behavior in a cohort of gay men.
