국내 30-40 대 장년의 식이 나트륨·칼륨 비 및 음식군 에너지 섭취 비율과 비만과의 관련성 : 제 6~7기 (2013-2018) 국민건강영양조사를 바탕으로

Abstract

Nutrient imbalance, exceptionally high sodium, and low potassium intake have been reported to cause obesity. Thus, this study analyzed the relationship between the Na/K intake ratio and obesity. The subjects of this study were 7,523 persons aged 30-49 from the 6th~7th period (2013-2018) of the Korean National Health and Nutrition Examination Survey. Obesity was defined as BMI ≥25 kg/m2 and waist circumference ≥ 90cm for men and ≥85cm for women. The Na/K intake ratio was based on 24-hour recall data. A total of 24 food groups were classified according to a classification system provided by the Korean Nutrition Society. To analyze the relationship between the Na/K intake ratio and obesity, Generalized Linear Model (GLM) and logistic regression analysis were used. As a result of the analysis of the relationship between Na/K intake ratio and obesity, T3 was 1.273 times (CI: 1.125-1.440, P0.001) T1 in BMI criteria, and T3 was 1.244 times in waist circumference (CI: 1.089-1.422, P=0.005). Also, among those with a Na/K intake ratio of 1 or higher, food intake to total energy intake was analyzed according to obesity. The food group with the highest intake ratio in the obese group was beverages, alcoholic beverages, tea, noodles, dumplings, soups, fried foods, and kimchi (P0.005). Therefore, it is necessary to present the contents of an appropriate Na/K intake ratio and energy intake control during weight control education for obese people.
