Background: Pediatric obesity disproportionately affects youth in rural areas. However, few treatments target the barriers rural families face. iAmHealthy is a rurally tailored pediatric obesity treatment delivered via televideo that is specifically designed to address barriers for rural populations.

Objective: The current project is a feasibility trial of iAmHealthy in comparison to a newsletter control conducted in 4 states within the IDeA States Pediatric Clinical Trials Network (ISPCTN). Here we report the outcomes related to child health (child and caregiver BMI, dietary intake, and physical activity) and explore the relationship between intervention dose (number of contact hours) and health outcomes in these rural families.

Design/Methods: Eligible participants (n=104) included rural children (ages 6-11) with a BMI %ile > 85th and their primary caregivers. Rural families were recruited from primary care clinics and randomized to the iAmHealthy + Newsletter arm (n=52) and to the Newsletter arm (n=52). The iAmHealthy condition included 26 contact hours over 6 months utilizing televideo group and individual sessions focused on behavioral, nutritional, and exercise topics. Newsletters were delivered via USPS monthly. Dietary intake was assessed using the 24-Hour Food Recall. Physical activity was assessed using wGT3X-BT ActiGraph accelerometers.

Results: Participants were 55.8% female, 61.5% Non-Hispanic White, and 21.2% Non-Hispanic Black. The mean changes in child BMI from baseline to post-intervention were 0.32 (p=0.44) and 1.25 (p=0.001) in the iAmHealthy arm and Newsletter arm, respectively. There were no significant differences between the interventions with respect to change in caregiver BMI (p=0.56), servings of sweetened drinks (p=0.94), servings of fruits and vegetables (p=0.52), or number of junk food items (p=0.26) consumed per day. Moderate to vigorous physical activity in the Newsletter arm significantly decreased by 28.74 minutes (p=0.02) but not for iAmHealthy participants who had a decrease of 14.64 minutes (p=0.07). Dose was not a significant predictor of change in child (p=0.86) or caregiver BMI (p=0.81) for participants in the iAmHealthy condition.

Conclusion(s): Results signal that the iAmHealthy intervention was protective against the significant BMI gains and physical activity decreases seen in the Newsletter arm. Also, dose was not related to change in BMI for caregivers or child. These results suggest that a future fully powered randomized clinical trial of iAmHealthy is warranted.
