Brief summary
The study will pilot a randomized control trial to investigate the feasibility and preliminary efficacy of two distinct parent treatments on a dietary intervention for overweight and obese adolescents.
Detailed description
Investigators will recruit overweight or obese adolescents (BMI \>85th percentile) and parent(s) (BMI \>25 kg/m2). Families will participate in one of two 4-month treatments: 1) TEENS+Parents as Coaches (PAC), engaging parents as helpers in their child's weight management, or 2) TEENS+Parent Weight Loss (PWL), engaging parents in their own weight management. All adolescents will participate in TEENS+, which includes behavioral support, nutrition education, and supervised physical activity. For the adolescents, intervention will consist of weekly 1 hour exercise sessions and alternating weekly 1 hour behavioral and nutrition group sessions. Parents will also attend the nutrition sessions and participate in a behavioral parent-only biweekly group. Parent behavioral group sessions will be specific to the treatment arm (e.g. PAC or PWL). Assessments will consist of anthropometric measures, psychological surveys, and nutritional evaluations. Assessments will be completed at baseline, post-test and 3-month follow-up.
Interventions
BEHAVIORALParents as Coaches
PAC (modeled after NIH-funded NOURISH) focuses on parenting strategies to support and facilitate their child's weight management via family-based change. Each visit includes group psychoeducation and discussion, focused on parenting strategies to facilitate healthy weight management in their child(ren). Topics include focus such as role modeling, strategies for healthy lifestyle changes, and how to be a coach to your teen.
BEHAVIORALParent Weight Loss
In PWL parents will be given a weight loss goal of 1-2 lbs/week, as well as specific calorie and fat prescriptions, PA goals, and instructions to self-monitor key information. Parents will receive training in core behavioral weight loss strategies (e.g., goal setting, stimulus control) and techniques to help them achieve these goals and will also receive personalized feedback throughout the program
