简要总结
Primary Aim: To test the efficacy of an elementary school-based, school nurse-led weight management program to reduce excess weight gain among children, 8 to 12 years old who are overweight and at risk of overweight by increasing healthy dietary practices and physical activity levels and decreasing sedentary practices.
Primary Hypothesis: Relative to the control condition, the children receiving the intervention will have a significantly lower body mass index (BMI), following implementation of the 9-month intervention, controlling for baseline values.

结局指标
主要结局
Child Body Mass Index (BMI)
时间窗: Measurement data will be collected at baseline prior to randomization and 12 (YR-1 post intervention), and 24 (YR-2 follow up) months post randomization
Body Mass Index (primary outcome) is the recommended method of assessing overweight among children and was calculated with the formula: weight (kg)/height (m) 2. To determine child BMI percentile, we calculated age- and gender-adjusted BMI with Centers for Disease Control and Prevention (CDC) growth charts.. The primary outcome measure is BMI Z-Score, which indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean. Negative numbers indicate values lower than the mean and positive numbers indicate values higher than the mean. A higher Z-score is a less favorable outcome when assessing overweight/obesity across conditions in a healthy weight management intervention..
次要结局
- Activity(The measure was collected at 12 months (YR-1 post intervention), following randomization with result adjusted for baseline value, percent body fat, sex and age)
- Total Quality of Life(Measurement data will be collected at baseline prior to randomization and 12 (YR-1 post intervention) , and 24 (YR-2 follow up) months following randomization)
- Dietary: Healthy Eating Index(The measure was collected at 12 months (YR-1 post intervention) following randomization with result adjusted for baseline value, percent body fat, sex and economic assistance)
