Exercise prescription for underprivileged minorities.

Physical inactivity is a growing epidemic in industrialized nations, contributing to the increasing prevalence and worsening of many chronic disease processes such as diabetes mellitus, cerebral vascular disease, and depression. It is well recognized that certain subpopulations are less likely to partake in physical activity than the population at large. Many minority populations, especially those of lower socioeconomic status, and women and children within these groups, are the most likely to be inactive.
