여대생의 아침 결식 여부에 따른 식행동 및 식이 섭취 상태와 DQI-I를 기준으로 한 식사의 질 평가

Abstract

The purpose of this study was to evaluate the dietary behavior, nutrient and food intake status and dietary quality based on nutrient and food group intake and Diet Quality Index-International (DQI-I) according to breakfast eating status in female university students. The survey was conducted using questionnaires and 3-day dietary records for 181 female university students residing in Seoul, Gyunggi, and Gangwon. The subjects were divided into two groups by frequency of breakfast eating: skipping breakfast (frequency of eating breakfast under 4 times/week, n=69) and eating breakfast (frequency of eating breakfast over five times/week, n=112). The skipping-breakfast group was significantly lower in its frequency of having lunch than that of the eating-breakfast group. There was no significant difference of energy intake between the two groups; however, the intake of carbohydrate, fiber, folate, vitamin C, vitamin E, Ca and Fe in the skipping-breakfast group was significantly lower than those in the eating-breakfast group. There was no significant difference in Korean's Dietary Diversity Score (KDDS) between the skipping-breakfast group(4.65±0.56) and eating-breakfast group (4.73±0.50). The average DQI-I of the skippingbreakfast group 56.96±9.04) was significantly lower than that of the eating-breakfast group (61.32±7.99). In conclusion, female university students with a high frequency of skipping breakfast may have a lower diet quality and DQI-I score. Therefore, in support of proper dietary management, it is necessary to promote and support breakfast eating.
