The purpose of this study was to investigate the sweets preference, food frequency, dietary habits, and nutrition knowledge of middle school students who like sweets. A survey instrument consisted of a self-administered questionnaire, a food frequency questionnaire, and anthropometric measurements. Three hundreds thirty five students aged 13 to 15 years old were divided into two groups, Sweets Liking Group (SLG) and a control group based on the subjects’ scores for dietary habits, sweets preference, and food frequency. For dietary habits, the score for meal regularity was significantly lower in the SLG group compared to the control (p＜0.001). In addition, the SLG group was more likely to skip breakfast (p＜0.001), eat inadequate amount of meals (p＜0.001), and consume yellow-green vegetables less frequently (p＜0.001) than the control. The subjects’ nutrition knowledge was assessed using 20 questions representing five categories, including functions of nutrients, nutrition and health, food pyramid and food groups, healthful snacking and the right dietary attitude. The total scores for nutrition knowledge indicated that the SLG had a poorer nutrition knowledge for all five categories than the control (boys p＜0.05, girls p＜0.01). For food frequency, the SLG consumed more sweets but less grains, cereals, fishes, beans, vegetables, and milk and milk products than the control (p＜0.001). Strong positive correlations appeared between sweets preference, sweets frequency, and sweets-related dietary habits; and all were negatively correlated to nutrition knowledge. Sweets frequency was negatively related to meal regularity, breakfast consumption, meal adequacy, and balanced meals. The findings suggest that nutrition education is necessary to improve the dietary pattern, especially sweets consumption, of Korean young adolescents.
