An Examination of Sex Differences in Relation to the Eating Habits and Nutrient Intakes of University Students

ObjectivesTo examine sex differences in eating habits and nutrient intakes and explore whether eating habits mediate the effects of sex on nutrient intakes and whether sex moderates the effects of eating habits on nutrient intakes.MethodsCross-sectional survey of eating habits and food-intake frequency in a convenience sample of college students.ResultsMale students (n = 172) consumed a higher energy content from fat, a larger amount of fiber, and more fruits and vegetables, and engaged less often in various healthful eating habits (eg, reading food labels, having breakfast) than female students (n = 316). Sex predicted the 3 dietary nutrient intakes partially through eating habits. Interactions between sex and eating habits were nonsignificant.Conclusions and ImplicationsResults reinforce that university students’ nutrient intakes are less than ideal. Women and men may have different needs for nutritional improvement. However, the effects of health promotion concerning eating habits may be similarly effective between the sexes.
