Shared Weight and Dietary Changes in Parent-Child Dyads Following Family-Based Obesity Treatment.
Sommaire de l'article
The primary objective was to determine whether children and their participating parents undergoing family-based behavioral treatment (FBT) for obesity show similar dietary changes following treatment, and if so, whether these shared dietary changes explain the similarity in weight change within the parent-child dyad.
Data come from a randomized controlled trial of 148 parent-child dyads who completed FBT and were followed over a 2-year maintenance phase. Energy-dense, nutrient-poor foods ("RED" foods) and fruit and vegetable intake were assessed across time.
Maintenance of lower RED food intake following FBT predicted weight maintenance in children and in parents (ps < .01), and dietary and weight changes were correlated within parent-child dyads (ps < .01). Most interesting, the similarity in long-term weight maintenance between children and their parents was predicted by the similarity in long-term changes in RED food intake between children and their parents (p < .001).
These findings point to the important role of maintaining low energy-dense, nutrient-poor food intake for long-term weight maintenance in children and parents. Furthermore, these results suggest that the correlation between parent and child weight maintenance can be explained in part by similar long-term changes in energy-dense, nutrient-poor food intake.
