Abstract
OBJECTIVES
This study was conducted to examine the differences in food literacy between adults and older adults and the association of food literacy with food group intake.
METHODS
In total, 4,039 participants from the 2021 Survey for Food Consumption in Seoul were included in this study. The intake of whole grains, high-protein foods, total vegetables, vegetables excluding kimchi and pickles, fresh fruits, and milk and dairy products was assessed using a simple food frequency questionnaire. Food literacy was measured using a food literacy measurement questionnaire.
RESULTS
With the exception of milk and dairy, adults had a significantly higher proportion of insufficient food intake than older adults (p<0.001). Both adults and older adults with sufficient food group consumption had higher food literacy scores. Notably, the difference in food literacy scores by level of food intake was highest for fresh fruits (p<0.001). After adjusting for confounding factors affecting food literacy scores, a higher score was associated with a lower probability of having insufficient food intake in all food groups for both adults and older adults. Specifically, those in the highest food literacy score quartile were less likely to have insufficient intake of vegetables (odds ratio [OR], 0.35; 95% confidence interval [CI], 0.28 to 0.43) and fresh fruits (OR, 0.32; 95% CI, 0.24 to 0.43), compared to the lowest quartile.
CONCLUSIONS
Improving food literacy is an important factor for promoting healthy food intake in older adults as well as adults. Therefore, it is necessary to develop intervention programs to work toward this goal.
Summary
Korean summary
건강정보 이해능력(health literacy)은 노인에서 만성질환이나 인지능력과의 관련성이 보고되고 있으나 영양정보 이해능력(food literacy)에 대한 연구는 미비하다. 급변하는 식이 환경에서 식사 및 영양과 관련된 정보를 올바르게 이해하고 판단할 수 있는 영양정보 이해능력은 노인성 질환 예방에 중요하다. 본 연구에서 영양정보 이해능력과 식품군 섭취와의 상관성을 분석한 결과 영양정보 이해능력이 높은 노인이 건강한 식품 섭취 부족 위험이 낮았다. 특히 과일 섭취 부족 위험은 영양정보 이해능력이 높은 노인에서 뚜렷하게 낮았다. 국내 영양정보 이해능력 연구는 초기 단계로 주로 성인 대상으로 연구가 이루어져서 본 연구에서의 결과는 그 의의가 크며, 영양정보 이해능력 향상은 성인과 마찬가지로 노인에서도 건강한 식품 섭취를 위한 중요한 요인으로서 이를 위한 프로그램 개발이 필요할 것으로 사료된다.
Key Message
The study on food literacy among older adults in Korea is significant as previous research has mostly focused on adults. The results showed that older adults with higher food literacy score had lower risk of insufficient food intake as compared with those with lower food literacy score. Specifically, the risk of insufficient fresh fruits intake was the lowest among older adults with higher food literacy score. Therefore, improving food literacy is an important factor for promoting healthy food consumption among older adults.

Abstract
The Korea National Health and Nutrition Examination Survey is a nationwide health survey in Korea. This survey is composed of three parts: the Health Interview Survey, the Health Examination Survey, and the Nutrition Survey. The aim of this study was to refine the nutrition survey system in the Korean National Health and Nutrition Examination Survey (KNHANES). Based on the literature review, we summarized international survey systems and the limitations of the current system in Korea and proposed an improved system. We suggested the following: 1) A government agency which will be exclusively responsible for KNHANES overall is needed. 2) The current short-term nutrition survey should be a year-round survey. 3) The objectives of this survey should be written with more clarity and detail. 4) Biochemical measures in relation to nutritional status should be added. 5) The budget to set up various databases in the nutrition survey should be increased. 6) Various other issues should be addressed, including the definition of raw data (i.e., whether nutrient intake data per day is raw data), ethical issues in survey techniques, and strategies to produce evidence for the public using this survey data. Not all suggestions could be adopted in the short-term, but should be integrated into long-term goals for survey system improvement.

Abstract
Primary prevention of atherosclerosis is important for reducing morbidity and mortality from cardiovascular disease. As modifiable risk factors for atherosclerosis which appears and progresses in early life, obesity and hyperlipidemia are related with each other. Especially hyperlipidemia during adolescent period is closely related to cardiovascular morbidity and mortality in later life, but the association between anthropometric changes in growth period and lipids level in adolescence is not known yet. Therefore we investigated the effect of anthropometric changes in growth period on adolescent lipids level among 615 high school students in rural area of Korea. The study results were as the followings; In childhood, the weight and the height of boys didn't differ from those of girls, however, began to exceed them at 14 and 15 years old respectively. The body mass index(BMI) of both genders was appeared to increase with age. The BMI increase of girls was greater than that of boys from twelve years of age. The BMI slope (annual average increment of BMI; coefficient of regression line) of girls was greater than that of boys(t-test, p<0.01). The proportion of high obesity tracking group was 13.1%(82 persons). In multivariate analysis, total cholesterol and LDL-cholesterol were positively correlated with obesity tracking in boys; BMI slope and BMI at 7 years old in girls. The HDL-cholesterol didn't show any significant association with those factors. The triglyceride was related to BMI slope and obesity tracking in boy, but nothing in girls. In this study, the obesity at 7 years old, the BMI slope, and the obesity tracking are associated with adolescent serum lipid level. For primary prevention of cardiovascular disease, it is needed to develop more active prevention or health promotion program for children and adolesecents in Korea.
