Opportunities for women in sport have expanded, whereas the media-driven ideal female continues to have a slender body. To attain the body that society has promoted, college-age females are vulnerable to psychological disordered eating risk. This study examines relationships among physical activity, body composition, and psychological eating disorder risk among college females (N = 115). Study outcomes indicate: psychological measurements were 1 to 3% predictive of physical activity; low physical activity had the greatest body dissatisfaction and body fat; body dissatisfaction and drive for thinness were 71 to 74% predictive of psychological disordered eating risk; and body mass index and body fat were 19 to 31% predictive of physical activity and 10 to 31% predictive of psychological measurements.
