Evidence-based approaches for establishing the 2015 Dietary Reference Intakes for Koreans
Sangah Shin,Subeen Kim,Hyojee Joung 한국영양학회 2018 Nutrition Research and Practice Vol.12 No.6
BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs), a set of reference intake values, have served as a basis for guiding a balanced diet that promotes health and prevents disease in the general Korean population. In the process of developing DRIs, a systematic review has played an important role in helping the DRI committees make evidence-based and transparent decisions for updating the next DRIs. Thus, the 2015 KDRI steering committee applied the systematic review framework to the revision process of the KDRIs. The purpose of this article is to summarize the revision process for the 2015 KDRIs by focusing on the systematic review framework. MATERIALS/METHODS: The methods used to develop the systematic review framework for 2015 KDRIs followed the Agency for Healthcare Research and Quality and the Tufts Evidence-based Practice Center. The framework for systematic review of the 2015 KDRIs comprised of the 3 following steps: (1) development of an analytic framework and refinement of key questions and search terms; (2) literature search and data extraction; and, (3) appraisal of the literature and summarizing the results. RESULTS: A total of 203,237 studies were retrieved through the above procedure, with 2,324 of these studies included in the analysis. General information, main results, comments of reviewers, and results of quality assessment were extracted and organized by study design. The average points of quality appraisals were 3.0 (range, 0-5) points for intervention, 6.1 (0-9) points for cohort, 6.0 (3-9) points for nested case-control, 5.4 (1-8) points for case-control, 14.6 (0-22) points for cross-sectional studies, and 7.0 (0-11) points for reviews. CONCLUSIONS: Systematic review helped to establish the 2015 KDRIs as a useful tool for evidence-based approach. Collaborative efforts to improve the framework for systematic review should be continued for future KDRIs.

The aim of this study was to develop a reliable dietary questionnaire to assess human exposure to food-borne hazards. Eleven food-borne hazards were chosen as a priority control list through a literature review and advisory committees. The 11 food-borne hazards were phthalate, aflatoxin, bisphenol A, polycyclic aromatic hydrocarbons, dioxin, polychlorinated biphenyls, mercury, lead, cadmium, arsenic, and acrylamide. The characteristics, exposure level, and paths of these hazards were reviewed, and questionnaire items were identified to assess human exposure from the literature. A questionnaire was developed for each selected food based on its characteristics. Based on the items in the individual questionnaires, a comprehensive questionnaire, which contained demographic characteristics, job information, socioeconomic factors, health related lifestyles, and dietary behaviors, was developed. A 99-item food frequency questionnaire (FFQ) to assess food-borne hazard exposure was also developed. The FFQ included frequency of food intake during the previous year, container type for purchasing and storing food, and cooking method. The questionnaire developed in this study could be applied to assess dietary factors during an exposure assessment of food-borne hazards in a large population. A validation study for the questionnaire is needed before applying it to surveys. (Korean J Nutr 2011 44(1): 61 ~ 73)

청소년기의 골건강에 영향을 줄 수 있는 신체계측치와 사회경제적 요인, 출생 당시의 모체의 건강상태 및 모유수유, 대상자의 건강상태, 생활습관 및 식습관 요인을 분석한 본 연구의 결과를 요약하면 다음과 같다. 1) 조사 대상자의 평균 연령은 14.2세, 신장 162.7 ㎝, 체중 57.3 ㎏이었고, 비만 및 과체중 유병률은 27.3%였다. 우측 종골의 골밀도는 0.518 g/㎠, 골질량은 2.241 g이었다. 2) 월 3만원 이상 용돈을 사용하는 남학생의 골질량이 3만원 이하 용돈을 사용하는 남학생에 비해서 유의하게 높았고, 형제가 없는 남학생의 경우 골질량이 유의하게 높았다. 출생시 어머니의 나이가 30세 이전인 학생들의 골질량이 유의하지는 않지만 높은 경향이 있었다. 3) 골절 경험이 있는 남학생의 골절량이 골절 경험이 없는 남학생에 비해 유의하게 높았고, 2차 성징이 늦은 남학생의 골질량이 높았다. 영양제를 섭취 하지 않은 남학생의 골질량이 높았고, 활동적인 선체 활동과 규직적인 운동, 야외활동을 많이 하는 학생들의 골질량이 유의하게 높았다. 4) 다양한 음식을 골고루 섭취하는 남학생의 골질량이 유의하게 높았고, 충분한 물을 섭취할 때 남학생과 여학생의 골질량이 유의하게 높았다. 밥 위주의 전통식을 하루 두끼 이상 섭취하는 여학생의 골질량이 유의하게 낮았다. 치즈, 생선류, 시금치 및 무청나물의 섭취가 대상자들의 골질량에 관련성이 있었다. 5) 다중회귀분석 모델에서 선장, BMI, 운동 횟수, 시금치 또는 무청나물의 섭취횟수의 골질량 설명력은 64.9%였다. 이상의 연구 결과에서 청소년기 골질량 향상을 위해서는 규칙적인 운동과 선체활동으로 체지방률을 낮추고, 칼슘 급원 식품과 더불어 다양한 음식을 골고루 섭취하도록 해야 할 것이다. 따라서 본 연구의 결과를 토대로 청소년기 학생들에게 골질량 향상을 위해 신체 활동 증가를 통한 생활습관 교육 프로그램과 올바른 식습관 형성을 위한 식사 교육 프로그램을 실시한다면 이들이 성인이 되었을 때 발생 할 수 있는 골감소증 및 골다공증을 예방할 수 있을 것으로 사료된다. The purpose of this study was to investigate factors related to bone mineral contents (BMC) at os calcis of adolescents. The subjects were 604 students (327 boys and 277 girls) between 7th and 9th grade in Seoul, Korea. The mean age was 14.2±0.9 years. General characteristics were collected by a questionnaire, bone mineral contents (BMC) were measured in os calcis by Duel Energy X-ray Absorptiometry (PIXI, General Electronics, USA) and height and weight were measured by bioelectrical impedance analysis method (Inbody 4.0, Biospace Co. Ltd, Seoul, Korea). Mean BMC of os cal sis were 2.241 g. Height (p<.0001), weight (p<.0001), BMC (p<.0001) of boys were higher than those of girls. Percent body fat of girls, however, was higher than that of boys (p<.0001). Anthropometric measurement, pocket money, sibling, experience of fracture, pubertal stage, intake of supplements, physical or outdoors activity, and eating habit had significant influence on BMC of boys. Anthropometric measurement, physical or outdoors activity, and eating habit had significant influence on BMC of girls. Multivariate regression with adjustment for sex and age showed that BMC was associated positively with height, BMI, frequency of regular activity, and intake of spinach or radish leaves (all p<0.05), and negatively with percent body fat (p<.0000 and Korean traditional diet pattern (p=0.01). On the basis of these results, it is recommended to develop nutrition education and physical activity program for adolescents to improve BMC and prevent osteoporosis.

Objectives: The purpose of this study was to investigate the association between anxiety, depression and dietary behaviors among high school girls. Methods: The subjects were 1,922 students who are in first and second grade of high schools in Seoul, Daejeon, and the mean age was 17.0±0.6 years. The data was collected through self-reported questionnaires which included general characteristics, dietary intake, Bulimia (Bulimia Test-R), depression and anxiety assessment (HADS). Results: The average score of anxiety, depression, and bulimia were 7.0±4.1, 6.1±3.3, and 50.9±14.2, respectively. Twenty nine percent of the girls had depression disorder (mild 20.3%, moderate 8.1%, and severe 1.3%) and 42% of the subjects showed anxiety disorder (mild 22.1%, moderate 15.3%, severe 4.6%). Anxiety and depression scores were positively correlated with intake frequency of soda and fast food but negatively associated with vegetable and fruit intakes (p<0.001). Bulimia tends to increase by depression group. Also the more reach higher level of anxiety, the more have milk (p=0.022). Students in anxiety group have less snack (p<0.0001) than other students who have the normal level of anxiety. Conclusion: The prevalence of anxiety and depression disorder was high among high school girls and associated with unhealthy dietary pattern. Mental health care programs are necessary for better dietary behaviors of girl adolescents.
