Gender differences in college students' perceptions and satisfaction with body weight were examined. Females tended to perceivev themselves as overweight when they were not, failed to see themselves as underweight when they were, and many of those who did not see themselves as even slightly overweight wanted to lose weight. Although males reported some dissatisfaction with their bodies, they tended to want to gain rather than lose weight. Females dieted more frequently than did males, and nearly one-third of the females reported either self-induced vomiting or laxative use as a weight-loss strategy. The relationship between social pressure for female slenderness, dieting, and eating disorders are discussed.
