Establishment of education system based on the regional health promotion activity to prevent life style-related diseases in children

本研究旨在建立以学校为基础的儿童健康促进系统。小学（1177人）和初中（1064人）的男孩和女孩参加了研究。评估了以下项目：（1）身高和体重，身体成分，（2）生化和激素标志物，（3）生活方式相关因素，如食物和运动等。对于肥胖的评估，超重标准的百分比比BMI（身体质量指数）更可靠，尤其是在儿童时期。有显着的地区差异，血脂水平，表明除了遗传原因，干预和教育似乎有效地改善儿童血脂异常。瘦素与体重及超重程度呈显著相关。瘦素被证明是肥胖的指标之一，即使在儿童中。在儿童时期，饮食行为和最喜欢的食物已经存在性别差异。后续研究证实了研究中健康促进活动的有效性。以学校为基础的生活方式相关疾病预防系统对小学和初中的男孩和女孩都有效。

The purpose of the study was to establish a school-based system for health promotion in childrdn. Boys and girls in elementary schools (1177) and junior high schools (1064) joined the study. The following items were assessed: (1) body height and weight, and body composition, (2) biochemical and hormonal markers, (3) life style-related factors such as foods and exercise, etc. For assessment of obesity, percentage of overweight for the standard was shown more reliable than BMI (body mass index) especially in childhood. There were significant regional differences in serum lipid levels, suggesting that in addition to genetic causes intervention and education seemed effective to improve dyslipidemia in children. Fat-derived hormone, leptin, was significantly related with body weight and the degree of overweight. Leptin was demonstrated as one of the indicators for fatness even in children. There were gender differences in eating behavior and favorite foods already in childhood. Follow-up study demonstrated efficacy of the health promotion activity in the study. The school-based system for prevention of life style-related diseases is suggested effective for boys and girls in the elementary schoolas well as junior high school.
