본 연구는 국가 단위 검진 영양조사상 나트륨 섭취량과 총 칼로리 섭 취량이 정량적 관련이 있는지 알아본 연구이다. 나트륨 섭취량은 총 칼로 리 섭취량과 정량적 관련이 있으며, 음식 맛을 유지하는 현재 나트륨 포 함량을 유지하고, 나트륨 권장 섭취량에 해당하는 추정 총 칼로리 섭취량 은 1630 kcal 였다. 앞으로 나트륨 섭취량을 줄이는 방법으로써 총 칼로 리 섭취량과 관련된 후속연구가 이어지기를 기대한다.

46 Abstract
The relationship between total calorie intake and sodium intake based on 2014 Korean National Health and Nutrition Examination
Survey(KNHANES)
Ajou University Graduate School of Public Health Juneyoung Yoon
The International Health Organization (WHO) has recommended that avoid ingestion of processed foods that are high in sodium and add sodium as little as possible to foods in order to reduce early death from cardiovascular disease, however, the average sodium intake is still above the recommended level. The reason is thought to be not only the real difficulty of the eating habits but also the lack of understanding about the influence factors of sodium intake. This study investigated the relationship of total calorie intake on sodium intake among nutritional factors. It is a secondary data analysis study through the nutrition survey of the National Health and Nutrition Survey. Sodium intake was used as a dependent variable and a hierarchical linear regression analysis was performed using
47
statistically the factors influencing sodium ingestion (sex, age, body mass index, infectious disease) and total calorie intake as independent variables. The total caloric intake corresponding to the sodium 2300mg was estimated through the ROC curve analysis. In conclusion, the total calorie intake was quantitatively correlated with sodium intake, and the total calorie intake exceeding the sodium recommended level was from 1630 Kcal. In addition to the existing recommendations of sodium intake, efforts should be considered to reduce total calorie intake.
