Linking Primary Care, Communities, and Families to Prevent Obesity Among Preschool Children

Childhood Obesity and Primary Care Prevalence of childhood obesity has almost tripled in the last two decades Multi-level, multi-setting interventions are needed to address this complex problem NIH and other expert committees have recommended using primary care as an entry point for family-based interventions

Specific Aims: Net-WORKS Evaluate three-year parent-targeted intervention for preschool children Primary outcome change in child BMI z-score Randomized two-group design (N = 500)

EARLY CHILD & FAMILY EDUCATION (ECFE) Promote obesity- prevention & positive parenting practices Provide social support Modify social norms re: healthy eating & PA CHILD ACTIVITY LEVEL & PATTERNS ↑ Moderate-to-Vigorous Physical Activity ↓ Screen Time CHILD DIETARY INTAKE ↓ Sweetened beverage consumption ↓ High fat/high calorie snacks and meals ↑ Fruits and vegetables PEDIATRIC PRIMARY CARE raise awareness re: obesity risk brief guidance reinforcement of parent change COMMUNITY FOOD & PA PARTNERSHIPS YWCA Partnership: Increase access to PA opportunities and resources IATP partnership: Increase access to affordable healthful food FAMILY ADVOCATE links parents & each intervention level provides phone coaching support to parents PARENT Parental Knowledge Behavioral Intentions Self-efficacy Parenting support for PA and healthy eating Parent feeding practices Parenting style Parent modeling of PA and healthy eating HOME ENVIRONMENT ↑ Availability fruits & vegetables ↑ Availability healthy snack & meals ↑ Family Meals ↑ Physical Activity Opportunities ↓ Sedentary Activity Opportunities ↓Availability sweetened beverages ↓High fat/calorie snack foods CHILD BMI Z-SCORE

Phase 1: Pilot Trial; Years 1-2 Phase 2: Randomized Controlled Trial; Years 3-5 Phase 3: Dissemination and Sustainability; Years 6-7 Phases of Net-WORKS
