To prospectively examine the effects of a randomized school-based intervention on nutrition and physical activity knowledge and preferences, anthropometric measures, and fitness in low socioeconomic kindergarten children.
A total of 376 children completed a school-year combined dietary-behavioral-physical activity intervention and were compared with 349 control subjects (age 3.8 to 6.8 years).
The prevalence of overweight and obesity among the kindergarten children was 27.7%. Even though the intervention was not associated with between group differences in body mass index changes, it was associated with significantly (P < .05) greater increase in nutrition knowledge and preferences, physical activity knowledge and preferences, and improvement in fitness. There was a greater (P < .05) decrease in the number of overweight children in the intervention group (-31.9%) compared with the controls (-17.5%).
A kindergarten dietary-physical activity intervention applied by the kindergarten teachers, had no effect on body mass index changes between the groups, but improved nutrition and physical activity knowledge and preferences, improved fitness, and decreased the percent of overweight children. This intervention may play an important role in health promotion, prevention and treatment of childhood obesity.
前瞻性研究一项基于学校的随机干预对营养和身体活动知识和偏好、人体测量指标和低收入社会经济幼儿园儿童体能的影响。
共有 376 名儿童完成了一学年的综合饮食-行为-身体活动干预，并与 349 名对照儿童（年龄 3.8 至 6.8 岁）进行了比较。
幼儿园儿童超重和肥胖的患病率为 27.7%。尽管干预与体重指数变化的组间差异无关，但与营养知识和偏好、身体活动知识和偏好的显著增加（P<.05）以及体能的改善有关。干预组超重儿童的数量（-31.9%）比对照组（-17.5%）有更大的（P<.05）下降。
由幼儿园教师实施的幼儿园饮食-身体活动干预对组间体重指数变化没有影响，但改善了营养和身体活动知识和偏好，提高了体能，并减少了超重儿童的比例。这种干预可能在促进健康、预防和治疗儿童肥胖方面发挥重要作用。
