The children of parents who receive treatment for binge‐eating disorder experience improvements in disordered eating

Abstract

ObjectiveParental eating disorders are associated with disordered eating behaviors and psychopathology in their children, but it is not known whether parent treatment for binge‐eating disorder (BED) is associated with changes in child disordered eating behaviors and weight. Benefits or the “ripple” effect of treatment on untreated family members has been described in the obesity literature but not for BED.MethodParticipants evaluated for two randomized clinical trials for BED were screened for whether they had children. 76 parents completed baseline assessments about a school‐aged child; 62 were randomized to treatment, of whom 41 completed end‐of‐treatment assessments about their child's eating behaviors and weight (which were not targeted in the parent treatments).ResultsAnalyses revealed a significant effect of time on children's binge‐eating frequency and perceived weight category and a significant effect of parent medication on perceived weight category. Parental change in binge eating was associated significantly with changes in child secretive eating and food hoarding. Parental change in weight was not associated significantly with change in age/sex‐normed child BMI percentile, but had some associations with parent‐perceived child weight category.ConclusionsParent changes during their treatment were associated with changes in their children. Future longitudinal research is needed to examine when disordered eating emerges and clarify critical intervention timing related to children's age and parental BED. Further clinical research is also needed to assess the effectiveness of treating disordered eating at the family level.Public SignificancePrior cross‐sectional work has found that parents with BED are more likely to have children who engage in binge eating compared to parents without eating‐disorder psychopathology. This study was an initial exploration of change in children when parents received treatment in randomized controlled trials for BED. In this study, parent changes in binge eating were associated with reduced child secretive eating and food hoarding.
