Child and parent weight loss in family-based behavior modification programs

Overweight preadolescents and parents from 76 families were assigned to 1 of 3 behavioral treatment groups: parent/child target, child target, or nonspecific target. Percent overweight changes at the end of the 8-mo treatment and 13-mo follow-up were equivalent for children in the 3 treatment groups, but parents in the parent/child group lost more weight during treatment. Weight changes for parents and children increased through the 8-mo treatment. Patterns of maintenance showed that 40% of the children were within 20% of their ideal weight by the end of treatment, achieving nonobese status. 100% of the newly nonobese children in the parent/child group maintained nonobesity during follow-up, whereas only 30% in the child-alone group and 33% in the nonspecific group maintained nonobesity. In addition, weight losses for parents and children in the same family correlated positively at the end of treatment but not at follow-up. Results suggest that parental modeling may be important during treatment, but long-term results probably are due to parental reinforcement of child self-regulation.
