Brief summary
The goal of this study is to investigate whether eight weekly telephone coaching sessions or materials on lifestyle interventions can be beneficial for overweight and obese 8-12 year olds.
Detailed description
The proposed five-year cluster randomized controlled pediatric practice-based trial will compare the effectiveness of two practice-based interventions on improving diet and physical activity and reducing BMI among overweight and obese 8-12 year olds seen in pediatric practice: (1) Fitline-Coaching, consisting of a pediatric practice-based component plus Fitline counseling and workbook, or (2) Fitline-Workbook, consisting of the same practice-based component, but only the family workbook materials mailed over 8 weeks, with no referral to Fitline coaching. Sixteen pediatric primary care practices will be randomized to either the Fitline-Coaching (N=8) or the Fitline-Materials (N=8) condition. Five hundred and twelve parents and their children ages 8-12 with a body mass index (BMI) of \> 85th percentile (overweight or obese) will be recruited from the practices to achieve N=400 at 12 month follow-up.
Interventions
The eight weekly 30-minute Fitline calls provide personalized behavioral counseling and coaching to guide parents in improving their child's weight-related behaviors through targeted lifestyle changes recommended by the AAP for Stage 1, Prevention Plus. Calls are scheduled at a time convenient for the parent, including nights and weekends, with one nutritionist assigned to a family for consistency.
The workbook contains tips and practical strategies for implementing the AAP-recommended behavior changes discussed in the counseling sessions to support families in making lifestyle changes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Reducing BMI in overweight and obese children. | Baseline and 12-months post-baseline | BMI will be calculated from weight (kg)/height squared (in meters) and BMI z-score for age/sex will be determined using CDC growth charts for the child. It is hypothesized that the Fitline-Coaching group compared to the Fitline-Workbook group will have greater reductions in BMI z-scores at 12-month follow-up |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Improving the child's diet | Baseline and 6-months post-baseline | It is hypothesized that the Fitline-Coaching group compared to the Fitline-Workbook group will have greater improvements in diet at 6-month follow-up. This will be measured by 24 hour dietary recalls conducted 3 times at each time point. |
| Improving the child's physical activity | Baseline and 6-months post-baseline | It is hypothesized that the Fitline-Coaching group compared to the Fitline-Workbook group will have greater improvements in their level of physical activity at 6-month follow-up. This will be measured by the Physical Activity Questionnaire (PAQ-C). |
| Effect of the Fitline-Coaching on BMI through a composite measure of Social Cognitive Theory constructs | Baseline and 6-months post-baseline | It is hypothesized that the effect of the Fitline-Coaching on child BMI will be predicted by changes in Social Cognitive Theory constructs. Parents will complete a survey assessing: (1) anticipated benefits of the behavior change (outcome expectations) (23-item questionnaire); (2) perceived support and barriers to addressing their child's behavior changes (15-item questionnaire); (3) self efficacy in helping their child improve their diet and physical activity (12-item) questionnaire; (4) behavioral capability (12-item questionnaire); and (5) knowledge (7-item questionnaire). Children will complete a survey assessing (1) anticipated benefits of the behavior change (outcome expectations) (23-item questionnaire); (2) perceived support and barriers (67-item questionnaire); (3) self efficacy (16-item questionnaire); (4) behavioral capability (12-item questionnaire); and (5) knowledge (7 item questionnaire). |
| Cost Effectiveness | Baseline and 12-months post-baseline | Costs and health outcomes will be compared across conditions. Costs will include those of: (1) provider training and intervention, (2) office set-up and support, (3) intervention materials, and (4) Fitline coaching. The outcome will be change in BMI z-score. |
