Brief Motivational Interviewing to Reduce Child Body Mass Index

Summary

BMi 2 is a study that tests a behavioral counseling approach to reduce obesity in children. Practitioners (Pediatricians, Nurse Practitioners) were randomly assigned to one of three groups. The first group continued with standard care; in group 2, each practitioner delivered four study Motivational Interviewing visits with the parent/caregiver, and in group 3 in addition to the practitioner, a registered dietitian delivered 6 Motivational Interviewing visits. The primary outcome will be the child's percentile BMI change between the baseline and 2-year follow-up. Secondary outcomes will include behavior change around fruits and vegetables, sweetened beverages and exercise. Our hypothesis is that there will be a larger decrease in BMI percentile for children in group 3 than in group 2, and that children in group 2 will have a decrease in BMI percentile when compared to group one.

Conditions

• Childhood Obesity

Interventions

BEHAVIORAL

Standard Care

Practitioners will receive 2 hour obesity lecture and ½ day protocol training. Families recruited are given parent education materials. Outcomes will be collected at 1 year and 2 years after enrollment

BEHAVIORAL

Moderate Dose Motivational Interviewing

Practitioners receive 2 days of Motivational Interviewing and Behavioral Therapy Training and ½ day protocol training. Families recruited receive 4 x MI visits with the pediatric practitioner. Outcomes will be collected at 1 year and 2 years after enrollment

BEHAVIORAL

Higher Dose Motivational Interviewing

Practitioners receive 2 days of Motivational Interviewing and Behavioral Therapy Training and ½ day protocol training. Families recruited receive 4 x MI visits with the pediatric practitioner and 6 x visits (in phone or in person) with a Registered Dietitian, also trained in Motivational Interviewing. Outcomes will be collected at 1 year and 2 years after enrollment
