The purpose of this study is to determine whether a parent/guardian intervention for adolescent overweight/obesity more effective than a nutritional counseling education curriculum for reducing body mass index z-score (BMI Z-score) and related outcomes.

Rates of pediatric overweight (PO) among Americans are increasing and associated with significant psychological, social, quality of life, and health related outcomes. Because of the broad mental and physical health implications of PO and the difficulty in sustaining weight loss as an adult, it is of interest to find successful methods of weight loss and/or prevention of weight gain for obese children and adolescents. The family unit is a logical and empirically supported point of intervention for PO. Interventions on this level have shown good long term efficacy in young children, but there is very little research on adolescent family intervention. Within the eating disorder literature, there is growing support for the efficacy of family-based interventions (FBI) for adolescents. Given its trans-developmental applicability, focus on family as the unit of intervention, and utility in creating a healthy eating environment, FBI is a logical candidate for adaptation to intervention for PO and intervention for at-risk for overweight youth (FBI-PO). The core of the current project is to test the feasibility and efficacy of an adapted FBI manual for adolescent overweight and at-risk for overweight in an outpatient eating and weight disorders clinic and compare this modality to a minimal nutritional educational control (NEC) condition.

• Overweight
• Obesity

• Behavioral: FBT-PO
  The goal of FBT-PO is to resolve the eating disorder and return the patient to healthy psychosocial and physiological developmental trajectories through active family involvement across three treatment phases.
  Other Name: Family Based Therapy for Pediatric Overweight
• Behavioral: NEC
  Families assigned to NEC will receive a minimal nutrition and physical activity education curriculum across 16 sessions over 24 weeks.
  Other Name: Nutritional Educational Control Condition

• Experimental: FBT-PO
  Family Based Therapy for Pediatric Overweight.
  Intervention: Behavioral: FBT-PO
• Active Comparator: NEC
  Nutritional Educational Control Condition (NEC).
