Adolescence is the critical period of hormonal changes and rapid growth which demands balanced intake of nutrients. This study was conducted to investigate the relationship between obesity and dietary patterns in adolescent girls, mainly focusing on the impact of vegetable intake level on improving the quality of their diet. The subjects were 306 female high school students (normal 180, obese 126) from low income families. Dietary intakes were measured by 24‐hour recall method. We classified the subjects into high and low vegetable intake group from their vegetable intake data. The extent of dietary adequacy was evaluated by the estimated average requirement (EAR) and nutrient adequacy ratio (NAR). Food diversity was compared by dietary variety score (DVS). Average intake of Ca, Folate, vitamin C and riboflavin were below the level of EAR in all subjects. Higher risk of nutritional inadequacy was observed among obese girls compared to normal girls. Significantly higher intake of meat and fish group and higher DVS were observed for subjects with high vegetable intake. It appeared that adolescent female students with high vegetable intake had better dietary quality and nutritional status. These results suggest that acquiring sufficient intake of vegetables would be the most essential step in improving the nutritional adequacy of obese adolescent girls.
