Childhood obesity has been shown to be closely related to future obesity and comorbidities. As its prevalence and impact has increased significantly worldwide, researchers have focused on prevention and intervention. This study assessed a multifaceted intervention for elementary school children.A retrospective data collection with a cohort analysis was employed. A 16-week school-based intervention with nutritional intervention, physical activity, and behavioral education was designed and conducted by a multidisciplinary team for 1860 children aged 6 to 13 years. Basic information, anthropometrics, and physical fitness (PF) were recorded before and after the intervention. The differences compared with a reference group, and compared between subgroups, were analyzed.Significant favorable changes in body weight and composition were found. Children's height, weight, and muscle weight increased, whereas BMI, BMI z-score (zBMI), waist circumference, hip circumference, waist-hip ratio, waist-height ratio, body fat percentage, and visceral fat area decreased. Sit-ups and 800-m run time significantly improved. Girls exhibited a greater reduction in body weight outcomes; boys improved more in body composition and PF. Students with higher zBMI had a greater reduction in all anthropometrics; students with lower zBMI showed greater PF improvement, except for the 800-m run.The intervention improved weight measures, body composition, and PF. Subgroup differences suggested the need for sex- and weight-specific interventions.
儿童肥胖已被证明与未来的肥胖及合并症密切相关。由于其在全球范围内的患病率和影响显著增加，研究人员已将重点放在预防和干预上。本研究评估了针对小学生的多方面干预措施。采用回顾性数据收集和队列分析。一个多学科团队为1860名6至13岁的儿童设计并实施了一项为期16周的基于学校的干预措施，包括营养干预、体育活动和行为教育。在干预前后记录基本信息、人体测量数据和身体素质（PF）。分析与参照组相比以及亚组之间的差异。
发现体重和身体成分有显著的有利变化。儿童的身高、体重和肌肉重量增加，而体重指数（BMI）、BMI z评分（zBMI）、腰围、臀围、腰臀比、腰高比、体脂百分比和内脏脂肪面积下降。仰卧起坐和800米跑时间显著改善。女孩在体重结果方面的降幅更大；男孩在身体成分和PF方面改善更多。zBMI较高的学生在所有人体测量指标上的降幅更大；zBMI较低的学生除800米跑外，PF改善更大。该干预改善了体重指标、身体成分和PF。亚组差异表明需要针对性别和体重的特定干预措施。
