Objective: To evaluate the effectiveness of active parental involvement in a lifestyle intervention for the management of childhood obesity.
Design: Forty-two overweight children (32 girls and 10 boys), aged 9.2 +/- 0.2 years and with percent overweight 39.8 +/- 2.7%, were randomly allocated either to a child-and-parent group (N = 23) or a child-alone group (N = 19). Both groups attended a 3-month multidisciplinary program extended by booster sessions during follow-up, which involved many cognitive behavioral therapy principles and assigned high self-regulation to the children, but differed in parental involvement. Percent overweight was evaluated at baseline, and at 3, 6, and 18 months thereafter.
Results: There was no significant interaction between time and group or a significant difference between groups. Percent overweight decreased by 4.9 +/- 1.4 at 18 months (p < 0.001); the reduction occurred during the active phase of the treatment (0-3 months) and was maintained thereafter.
Conclusion: In the setting of the present study, the active parental involvement did not significantly modify the results of lifestyle interventions for children's overweight management.
