The frequency and associated health risks of obesity vary between men and women and among ethnic groups, according to Judith S. Stern, professor of nutrition and of internal medicine at UC Davis. "For example, although there is a greater incidence of obesity among women in the United States, obesity-associated illnesses and deaths are not comparable to those among men," says Stern. She adds that this disparity appears to be related to a difference in fat distribution. Women tend to carry excess fat in the lower body, while men are more likely to carry it in the upper body, resulting in greater health risks. Stern will chair a minisymposium devoted to discussions of "Gender and Ethnic Differences in Obesity and Fat Distribution" from 9:30-11:30 a.m. Tuesday, Oct. 22, in the Golden State Room.
