Assessment on Dietary Diversity According to Korean Dietary Pattern Score of Korean Adolescents and Children: Using 2007~2013 Korea National Health and Nutrition Examination Survey (KNHANES) Data

Abstract This study was performed to assess the nutrient intake and dietary diversity of Korean children and adolescents using the Korea n dietary pattern index developed in previous studies. For this study, 6,462 children and adolescents aged 7~18y who participated in the dietary intake survey (24h recall method) of the 2007~2013 KNHANES were sampled. The food items included in the Korean dietary index were jusik-ryu, guk/tang-ryu, gui/jjim-ryu, namul-ryu, yeomjangchaeso-ryu, jang-ryu and mitbanchan-ryu. All the subjects and both age groups (7~12y, 13~18y) were divided into quartiles. According to the results of this study, the range of the Korean dietary pattern score was 0~58 for all of the subjects and also in the 13~18 age group, and was 0~52 in the 7~12y age group. When the pattern score f or each food group was compared across the quartiles of the Korean dietary pattern score, in all the subjects as well as in the 7~12y a nd 13~18y age groups, the pattern score for jusik-ryu and yeomjangchaeso-ryu was highest in Q1~Q4. or all the food groups, the mean pattern score was highest in Q4. These results suggested that the Korean dietary pattern score is highly associated with jusik-ryu including rice and yeomjangchaeso-ryu including kimchi. Accordingly, it is considered necessary to develop an index that reflects the characteristics of Korean cuisine an d, at the same time, assesses the nut ritional status and food co nsumption tendency of Ko rean children and adol escents.Key words: Korean food, adolescent, child, KNHANES, dietary pattern score
