Abstract

Purpose: The purpose of the study was to analyze the status of dietary behavior and nutrition intakes according to the gender and the level of physical activity of adolescents. Methods: Data from 659 adolescents aged 13 to 18 years who participated in the Korea National Health and Nutrition Examination Survey (2017-2018) were analyzed. Collected data were analyzed using complex sampling data analysis with SPSS v. 27.0. Results: The adolescents were categorized into three groups based on their physical activity as follows: The first group with high physical activity (8.9%), a second group with normal physical activity (29.7%), and a third group without physical activity (61.4%). Boys showed significantly higher physical activity than the girls. Adolescents with high physical activity had a significantly lower body mass index than adolescents without physical activity, but their meal regularity, subjective health status, and recognition of body image were significantly higher. In terms of biochemical factors, adolescents with high physical activity had lower triglycerides and cholesterol than adolescents without physical activity, while hemoglobin and hematocrit were significantly higher. In addition, the intakes of energy, carbohydrates, proteins, fat, vitamin B1, niacin, calcium, phosphorus, sodium, potassium, iron increased significantly as adolescents' physical activity increased. Conclusion: The physical activity of adolescents had a positive effect on dietary behavior, lifestyle, and nutritional factors. Therefore, it is necessary to increase participation in physical classes in schools and develop various programs considering the level of physical activity among adolescents.

본 연구는 우리나라 청소년의 성별과 신체활동 수준에 따른 식행동과 영양섭취 실태를 비교하기 위하여 제7기 국민건강영양조사의 2,3차년도 (2017-2018년) 자료를 분석하였다. 총 659명 중 남학생은 344명 (51.5%), 여학생은 315명 (48.5%)이며, 하루 60분 이상 신체활동 실천 빈도를 기준으로 '신체활동 많은 군' 57명 (8.9%), '신체활동 보통 군' 196명 (29.7%), '신체활동을 하지 않는 군' 406명 (61.4%)으로 구분하였다. 신체활동이 많은 군의 81.5%는 남학생, 신체활동이 없는 군의 59.9%는 여학생이었다. 신체활동을 많이 하는 청소년일수록 아침식사, 점심식사, 저녁식사 빈도가 높았다. 남학생의 35.5%는 '마른 편', 여학생의 38.9%는 '비만'으로 인식하였으며, 남학생의 20.2%는 '체중증가', 여학생의 48.6%는 '체중감량' 노력을 하였으며, 남학생의 근력운동 실시비율이 유의적으로 높았다. 신체활동에 따라서는 신체활동이 많은 군에서 주관적 건강상태를 좋다고 인식하는 경우가 67.8%로 유의하게 높았다. 신체활동이 많은 군에서 자신의 체형을 마른 편 또는 보통으로 높게 인식하는 반면 신체활동이 보통인 군과 없는 군에서는 비만으로 인식하고 있어 유의적인 차이를 보였다. 생화학적 특성은 콜레스테롤은 여학생이 공복혈당, 혈중 헤모글로빈, 헤마토크릿, 혈중 요소질소, 혈중 크레아틴은 남학생이 유의하게 높았다. 신체활동이 많은 청소년들의 혈중 중성지방과 콜레스테롤은 낮은 반면 혈중 헤모글로빈, 헤마토크릿은 유의적으로 높았다. 혈중 요소질소와 혈중 크레아틴은 신체활동을 하지 않는 군이 유의적으로 낮았다. 총 에너지 중 탄수화물: 단백질: 지방의 섭취비율은 모든 군이 적정 섭취비율 범위이었다. 신체활동을 하는 군의 에너지, 탄수화물, 단백질, 지방의 섭취량은 신체활동을 하지 않는 군보다 유의미하게 높았다. 신체활동을 하는 군의 비타민 B1, 니아신의 섭취량이 유의적으로 높았다. 무기질은 신체활동이 많은 군의 칼슘, 인, 나트륨, 칼륨의 섭취량이 유의적으로 높았으며, 철의 섭취량은 신체활동이 보통인 군이 유의적으로 높았다. 이상의 결과, 성별에 따라 신체활동 수준의 차이를 보였으며, 규칙적인 신체활동은 청소년의 체질량지수, 식행동 및 영양소 섭취에 영향을 주었다. 따라서 학교 체육수업 참여를 통한 신체활동의 촉진과 청소년들이 흥미를 가지고 참여할 수 있는 다양한 스포츠 활동 프로그램의 개발과 운영이 필요하겠다.
