Modifications in parent feeding practices and child diet during family-based behavioral treatment improve child zBMI

OBJECTIVE: To examine associations between modifications in parent feeding practices, child diet, and child weight status after treatment and to evaluate dietary mediators. DESIGN AND METHODS: Children classified as overweight or obese and 7-11 years old (N=170) completed a 16-session family-based behavioral treatment program (FBT). Anthropometrics (standardized body mass index (zBMI)), Child Feeding Questionnaire, and 24-hr dietary recalls were collected at baseline and post-FBT. Linear regression predicted child zBMI change. Single and multiple mediation tested child dietary modifications as mediators between change in parent feeding practices and child zBMI. RESULTS: Restrictive parent feeding practices significantly decreased during FBT. Reductions in parent restriction, child weight concern, child total energy intake, and percent energy from fat, and increases in parent perceived responsibility, and child percent energy from protein, predicted reductions in child zBMI. Change in child total energy intake mediated the relation between parent restriction and child zBMI change after accounting for covariates and additional dietary mediators. CONCLUSIONS: FBT is associated with a decrease in parental restriction, which is associated with reductions in child relative weight, which was mediated by a decrease in child energy intake. Teaching parents to reduce children's energy intake without being overly restrictive may improve child weight.
