Utah's Gold Medal Schools program supports the adoption of school policies that provide opportunities for nutritious food choices and regular physical activity. The effectiveness of Gold Medal Schools was evaluated via anthropometric measurements and dietary and physical activity surveys. The study population included first-, third-, and fifth-grade elementary school students and parents from four schools in Tooele County, UT. Two schools implemented Gold Medal Schools (intervention) and two did not (comparison). Data were collected at baseline (June 2005) and 1 year (May 2006). Body mass index (calculated as kg/m(2)) z scores increased significantly in the comparison group (0.53+/-0.38; P<0.05), but not in the intervention group (0.21+/-0.47; P=0.484), from baseline to 1 year. Children in the Gold Medal Schools cohort reported drinking fewer soft drinks per day (excluding diet drinks) at 1 year (P=0.008) and walking or biking to school more often at baseline and 1 year (P<0.001) than non-Gold Medal Schools children. While children in both groups increased the days per week they walked or biked to school, a substantial improvement was observed for the non-Gold Medal Schools students only (P<0.001). Overall, this pilot study suggests that Gold Medal Schools positively impacted body mass index z scores and health behaviors among elementary-aged students.
犹他州的“金牌学校”项目支持学校采用相关政策，为学生提供选择营养食品和进行定期体育活动的机会。通过人体测量以及饮食和体育活动调查对“金牌学校”项目的成效进行了评估。研究对象包括犹他州图埃勒县四所学校的一、三、五年级小学生及其家长。两所学校实施了“金牌学校”项目（干预组），两所未实施（对照组）。在基线期（2005年6月）和1年后（2006年5月）收集数据。从基线期到1年后，对照组的体重指数（以kg/m²计算）z评分显著增加（0.53±0.38；P<0.05），而干预组未出现显著增加（0.21±0.47；P = 0.484）。与非“金牌学校”的儿童相比，“金牌学校”队列中的儿童在1年后报告每天饮用的软饮料（不包括无糖饮料）较少（P = 0.008），并且在基线期和1年后更经常步行或骑自行车上学（P<0.001）。虽然两组儿童每周步行或骑自行车上学的天数都有所增加，但仅在非“金牌学校”的学生中观察到了显著改善（P<0.001）。总体而言，这项试点研究表明“金牌学校”项目对小学年龄段学生的体重指数z评分和健康行为产生了积极影响。
