School Nurse-directed Secondary Obesity Prevention for Elementary School Children
Study Details
Study Description
Brief Summary
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.

Experimental: after school weight management program The 9-month after school weight management program called SNAPSHOT (Student, Nurses and Parents Seeking Healthy Options Together), with a focus on healthy food and activity practices will be directed by a school nurse and will include: 1) quarterly parent/child coaching sessions with the school nurse held in the participant's home; 2) 14 child group sessions led by the school nurse, held in a school setting 1-2 times a month; 3) 5 parent group sessions led by a school nurse held in a school setting. |

Outcome Measures
Primary Outcome Measures
- Child Body Mass Index (BMI) [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..
Secondary Outcome Measures
- 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]
The Healthy Eating Index-2015 (HEI-2015) will be assessed with multiple 24-hour dietary recall interviews. A score on the HEI-2015 ranges from 0 to 100, with 100 meeting the recommendations for all 13 components of the HEI-2015. The higher the score the better.
- 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]
Activity will be assessed with the MTI ActiGraph uniaxial accelerometer worn for a 7-day period. Time spent in each category of sedentary or moderate-vigorous physical activity was calculated as a percent of total wear time, with higher numbers indicating more time spent in the category.
- 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]
The 23-item Pediatric Quality of Life (QOL) child inventory or PedsQL 4.0 was used to assess physical, emotional, social and school functioning. Responses are reversed scored and transformed to a 0 to 100 scale which is used to calculate a total health-related quality of life summary score (mean of 23 items) which includes a physical health summary score (mean of 8 physical functioning items) and psycho-social health summary score (mean of 15 emotional, social and school functioning items). A higher score indicates better child-reported health-related quality of life.
