Centers for Disease Control (CDC) guidelines recommend schools use a coordinated health approach to support healthy eating and physical activity. This study examines whether the number of healthy eating and physical activity programs and activities used by schools and their perceived success relate to students' health-related fitness. This observational study used data from the Healthy Zone Schools Program. Data (collected in 2017-2019) were integrated from three sources: (1) school surveys, (2) FitnessGram, and (3) the Texas Education Agency. Independent variables were the number of health promotion programs and activities and their perceived success; dependent variables were meeting Healthy Fitness Zone Standards (HFZ) for aerobic capacity and body mass index (BMI). We used mixed-effects logistic regression models. Fifty-six schools were in the analytic sample ( = 15,096 students with aerobic capacity data and = 19,969 with BMI data). Results indicated the perceived success of physical activity programs/activities was significantly associated with students meeting HFZ standards for aerobic capacity (OR = 1.32, CI = 1.06-1.63). There was a significant direct association between the number of physical activity and healthy eating activities implemented (OR = 1.04, CI = 1.01-1.06) and students meeting HFZ for BMI. Schools using multiple health programs and activities need to balance the number provided with their capacity to maintain success.
疾病控制中心（CDC）的指导方针建议学校采用协调一致的健康方法来支持健康饮食和体育活动。本研究考察学校所采用的健康饮食和体育活动项目及活动的数量及其感知到的成功与学生的健康相关体能是否有关。这项观察性研究使用了来自健康区学校项目的数据。数据（于2017 - 2019年收集）整合自三个来源：（1）学校调查，（2）体能测试，以及（3）德克萨斯教育机构。自变量是健康促进项目及活动的数量及其感知到的成功；因变量是达到有氧能力和体重指数（BMI）的健康体能区标准（HFZ）。我们使用了混合效应逻辑回归模型。分析样本中有56所学校（有氧能力数据的学生有 = 15,096名，BMI数据的学生有 = 19,969名）。结果表明，体育活动项目/活动的感知成功与学生达到有氧能力的HFZ标准显著相关（OR = 1.32，CI = 1.06 - 1.63）。实施的体育活动和健康饮食活动的数量与学生达到BMI的HFZ之间存在显著的直接关联（OR = 1.04，CI = 1.01 - 1.06）。使用多个健康项目和活动的学校需要在提供的数量与保持成功的能力之间取得平衡。
