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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Coaching | Active Comparator | A parent support component consisting of eight weekly telephone counseling calls by centrally located nutritionists to provide parents coaching tailored to their family's unique needs to help them set goals and make targeted lifestyle changes recommended by the American Academy of Pediatrics (AAP) for Stage 1, Prevention Plus, accompanied by a parent booklet |
|
| Materials | Active Comparator | Parents will receive the same educational materials provided in the Fitline family workbook mailed over 8 weeks to control for weekly contact and educational curriculum, but no Fitline counseling. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Coaching | Behavioral | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Reducing BMI in overweight and obese children. | 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 | Baseline and 12-months post-baseline |

It is hypothesized that the Fitline-Coaching group compared to the Fitline-Workbook group will have greater reductions in BMI z-scores at 6-month follow-up | Baseline and 6-months post-baseline |
| Measure | Description | Time Frame |
|---|---|---|
| Improving the child's diet | 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. | 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 12-month follow-up. This will be measured by 24 hour dietary diet recalls conducted three times at each time point. |
| Baseline and 12-months post-baseline |
| Improving the child's physical activity | 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). | Baseline and 6-months post-baseline |

| Effect of the Fitline-Coaching on BMI through a composite measure of Social Cognitive Theory constructs | 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). | Baseline and 6-months post-baseline |

| Cost Effectiveness | 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. | Baseline and 12-months post-baseline |
