NOURISH-T+: Promoting Healthy Eating and Exercise Behaviors

This project employs a cluster randomized, controlled, repeated measures trial study design, with parent-child dyads assigned to an evidence-informed manualized, social-cognitive parent intervention (NOURISH-T+) or to a comparison group (Enhanced Usual Care group - Brief NOURISH-T+). NOURISH-T+ stands for Nourishing Our Understanding of Role modeling to Improve Support and Health for Healthy Transitions.

Parents of pediatric cancer survivors (ages 5-14 years) with overweight and obesity, and off treatment for at least 6 months will be recruited across multiple pediatric oncology clinic sites. The University of South Florida (USF) serves as the coordinating data management and centralized research and intervention team and will also recruit eligible participants from its pediatric oncology clinic.

NOURISH-T+ targets parents as agents of change by providing intensive parent skills training emphasizing role modeling of positive health behaviors to foster the development of healthy eating and physical activity in pediatric cancer survivors. The NOURISH-T+ group will have 6 weekly, 1-1.5 hour, manualized sessions delivered using video-conferencing. There will be 2 additional brief sessions where the child will participate along with their parent to promote child engagement. Additionally, there will be one session with a pediatric oncology dietician based out of Nicklaus Children's Hospital who will discuss personalized nutritional strategies. Brief booster sessions at 2-, 4-, 8-, and 10- months will maximize retention and follow-up participation. NOURISH-T+ content is theory-based, manualized, and builds upon strengths of our prior work with NOURISH-T (our pilot) and NOURISH (our work with otherwise healthy overweight and obese children).

Parents randomized to Brief NOURISH-T+ will participate in one information session moderated by a USF-based interventionist using videoconferencing. Session content is taken from the publicly available We Can! Manual. Parents in this group will receive nationally available web-based brochures on pediatric overweight/obesity on two occasions during the 6 weeks that NOURISH-T+ families participate in the study. Check-ins will take place at 2-, 4-, 8-, and 10- months post-intervention.

Outcome measures will be completed at baseline, 3-, 6-, and 12-months post-intervention.
