Brief Summary

The purpose of this study is to evaluate the efficacy of an intervention (KAN-DO: Kids \& Adults Now - Defeat Obesity) encouraging postpartum mothers and their preschool-aged children to work together to promote healthy eating, increase physical activity, and reduce sedentary behaviors. Via instruction in parenting skills and behavior change strategies, the goal is relative weight maintenance in children of healthy weight, and relative weight reduction in overweight children. The intervention will focus on a child (2-5 years of age) and his or her overweight or obese mother, who has just delivered a second or subsequent baby.

Study Arms (2)

1

ACTIVE COMPARATOR

Participants receive monthly newsletter (for 10 months) including general health and reading information for child and mother and incentives for completing the baseline and 2 follow-up assessments

Behavioral: KAN-DO

EXPERIMENTAL

Mothers and preschoolers in the intervention group will receive monthly mailed family kits that encourage interactive mother/child exercises for healthy lifestyle change. Mailings are supported by counseling calls and two in-person motivational/informational group sessions. The content of the intervention addresses parenting skills, healthy eating, and physical activity. Families can earn $40 for returning postcards describing their activities in the past month.

Behavioral: KAN-DO

Interventions

KAN-DO BEHAVIORAL

The 10 month KAN-DO intervention includes eight mailed interactive activity modules involving both the preschooler and mother that include relevant printed materials emphasizing parenting skills, healthy eating habits and increased physical activity. Mailed kits will each be followed by a supportive telephone counseling session based on motivational interviewing techniques. Mailed modules and telephone calls will be supplemented with two in-person motivational and informational sessions (at the beginning and in the middle of the intervention period). The Active Comparator group will receive monthly newsletters over the 10 month period related to boosting reading skills in their preschool children.
