About

This study will train primary care providers to counsel families on behavior change that is aimed at reducing the rate of weight gain in at-risk children.

Full description

BACKGROUND:

In addition to family, school, and community, primary care is a promising setting for childhood obesity prevention. However, most pediatric primary care providers are not trained to deliver behavior modification interventions and, according to preliminary data, are less likely to address obesity prevention when they perceive insufficient time during well-care visits.

DESIGN NARRATIVE:

This is a controlled study of obesity prevention, with group randomization of two standardized 12-month intervention strategies at the practice level. The intervention strategies are based on the behavioral economics theory and will be delivered by primary care providers after training in behavior modification. The first strategy will target change in multiple behaviors, while the second strategy will target only one behavior (beverage consumption). These two interventions will be compared to an active control intervention that is unrelated to weight (bullying prevention). Six to seven primary care practices will be randomized to each arm with 21 patients per practice, for a total of 17 practices and 350 patients. The primary aim is to demonstrate that either obesity prevention intervention will result in less body mass index (BMI) increase (adjusted using z-score) in children age 8 to 12 years who are at risk for overweight (BMI 50th-95th percentile), as compared to a control intervention. The study also hypothesizes that the multiple-behavior intervention, the single-behavior intervention, or both will result in less adjusted BMI increase than the control intervention at 24 months post-randomization, with no a priori assumption in differences between the two obesity prevention strategies. Blood pressure, insulin resistance, dyslipidemia, and oral health status will be secondary outcomes. Intermediate behavioral outcomes and process data will be collected.

158 participants in 3 patient groups

Healthy Lifestyle (Active Intervention)

Other group

Description:

Parents and children in this program which will participate in a series of consultations and activities focused on multiple healthy interventions including healthy eating, drinking, and physical activity. The children will participate in a variety of age-appropriate games, activities and exercises that are focused on healthy eating, drinking, and physical activity. In addition, your child will receive information on developing healthy interpersonal and social skills.

Treatment:

Behavioral: Multiple behavior interventions

Healthy Drinks (Active Intervention)

Other group

Description:

Parents and children in this program will participate in a series of consultations and activities focused on a single intervention, the effects of beverage choices on diet, general health and teeth health. The children will participate in a variety of age-appropriate games, activities and exercises that are focused on beverages and health. In addition, your child will receive information on healthy nutrition, physical activity, and interpersonal and social skills.

Treatment:

Behavioral: Single behavior intervention

Social and Leadership Skills (Control Intervention)

Other group

Description:

Parents and children in this program will participate in a series of consultations that are designed to help your child learn strategies to make and keep friends, to express feelings appropriately, and to successfully decrease conflicts that often occur at school among children. The children will participate in a variety of age-appropriate games, activities and exercises that are focused on these friendship making strategies. In addition, your child will receive information on healthy nutrition and physical activity. There is o intervention with regards to healthy weight.

Treatment:

Behavioral: Control Intervention unrelated to weight
