Purpose: Obesogenic environments in children, in particular excessive intake of sodium, generate hypertension, which is a major risk factor for chronic diseases. Methods: In all, 725 children, 379 boys and 373 girls, aged 8~9 years were recruited from seven elementary schools in Kuro-ku, Seoul. To e...

과량의 나트륨 섭취가 인체에 미치는 부정적인 영향은? | 7-9 비만발생에는 다양한 형태의 식이섭취가 복합효과로 나타나지만 과량의 나트륨 섭취가 비만과 관련있다는 연구논문이 제시되고 있다. 나트륨 (Na)은 혈액량 조절, 삼투압 평형, 세포막 전위 조절 및 영양소이동 등 세포의기본적인 기능을 위하여 필수적인 전해질이지만 과다한 나트륨의 섭취는 체액이 배설되지 않고 체내에 머무는 저류를 유도하고 고혈압 등 심혈관 질환, 2형 당뇨 및 복부비만 등 만성질환의 주요한 위험요인이 된다.10-13 따라서WHO에서는 하루 생리적 요구량인 2 g 이내로 나트륨 섭취를 줄이면 혈압과 만성질환의 위험이 감소한다는 보고하였으며, 메타분석에서도 나트륨 제한 및 칼륨, 칼슘 섭취의 증가가 혈압 강하효과를 나타내고 있다고 한다. | |
나트륨 기호도가 형성되는 시기는? | 최근, 한국소아의 나트륨 섭취량이 계속적으로 증가하는 추세이다. 나트륨 기호도는 6세 이전에 이미 형성된다는 연구와 함께 소아기의 대사적 특성이 성인시기로 이어지는 경향이 크므로 영유아기부터의 식습관 관리가 중요하다.7-9 비만발생에는 다양한 형태의 식이섭취가 복합효과로 나타나지만 과량의 나트륨 섭취가 비만과 관련있다는 연구논문이 제시되고 있다. | |
다른 연령대에 비해 소아 비만의 큰 문제점은 무엇인가? | 5%로, 다른 연령대에 비하여 비교적 높게 나타났다.1-3 소아 비만의 큰 문제점은 75%가 성인비만으로 이어져서 당뇨, 고혈압, 이상지질혈증, 인슐린저항성 및 동맥경화 등 만성대사성 질환의 위험을 증가시키는 것이다.4-6 |
