Evaluation of nutrient intake and food variety by age in Korean adolescents: Based on 2010~2012 Korean National Health and Nutrition Examination Survey / 한국영양학회지

ABSTRACT

PURPOSE: This study was conducted to investigate the nutrient intake and food variety in Korean adolescents. METHODS: We analyzed 1,555 adolescents aged 12 to 18 years using data from the combined 2010~2012 KNHANES (Korean National Health and Nutrition Examination Survey). In this study, subjects were divided according to age group (12~14 y, 15~18 y). The nutrient intake, ND (nutrient density), food intake and food score from each food group, variety and food intakes of meals, DDS (dietary diversity score), and GMVFDO (grain, meat, vegetable, fruit, dairy and oil food group) were analyzed using data from the 24-recall method. RESULTS: The results showed that the 15~18 age groupskipped breakfast significantly more often than the 12~14 age group (p < 0.0001). The 15~18 age group consumed significantly higher quantities of fat per 1,000 kcal compared to the 12~14 age group (p = 0.0069). Regarding food variety, the 15~18 age group showed a significantly higher intake (p < 0.0001) and score (p < 0.0001) from beverages than the 12~14 age group, whereas the 15~18 age group showed a significantly lower intake (p = 0.0084) and score (p = 0.0253) from milk than the 12~14 age group. In addition, DDS in the 15~18 age group (4.33) tended to be lower than that of the 12~14 age group (4.44) (p = 0.0727). CONCLUSION: Proper dietary management regarding meal variety is needed for the 15~18 age group, and more systematic studies to investigate the meal variety roles of adolescents are required.
