Ovulatory dysfunction is common in patients with eating disorders. However, many women engage in pathologic dieting behaviors without meeting the current diagnostic criteria for anorexia or bulimia nervosa. Clinical eating disorders are only the most extreme form of pathologic eating attitudes and behaviors that are present in many young women. Specific food choices and nutrient intakes may be associated with altered gonadal hormone status of these dieters. This cross-sectional study was conducted to describe the nutritional characteristics of college-aged women defined by their eating attitudes and behaviors with a previously described questionnaire. We evaluated dietary intake, body composition, and selected biochemical indicators in 76 undergraduate women. Serum concentrations of estradiol, progesterone, lipids, and carotenoids were measured on days 6, 21, and 28 of one menstrual cycle. Dietary assessment was based on food records at two 3-d intervals during the cycle. Ovulatory status was definitively determined on the basis of biochemical data for 46 of the women. Increased degree of pathologic dieting was associated with a significantly lower intake of dietary fat (P < 0.02), despite similar mean body mass index and body composition across the eating pathology groups. Serum concentration of alpha-carotene was significantly greater (P < 0.005) in association with a greater degree of eating pathology. With ovulation as a between-group factor, serum lutein concentration and dietary intake of energy and fat differed significantly between groups (P < 0.003). Nutritional characteristics associated with pathologic dieting behavior may also be associated with menstrual irregularities in young women.
