A recent study in Appetite found that higher BMI is associated with an increased risk of progressing from binge-eating behavior to binge-eating disorder among U.S. adolescents. The findings emphasize the importance of early screening and intervention.
By Dr. Priyom Bose, Ph.D.May 28 2024Reviewed by Benedette Cuffari, M.Sc. A recent study published in the journal Appetite investigates the extent to which body mass index is associated with progression from binge-eating behavior to binge- eating disorder .
Importantly, an individual can engage in binge eating behaviors, which are relatively less severe than BED. In fact, among adolescents in the U.S., the prevalence of binge-eating behaviors is 2.5%. There remains a lack of data on the potential relationship between BMI and the progression of binge-eating behavior to BED. To this end, the central hypothesis of the current study was that BMI should be associated with a higher risk of BED, irrespective of individuals' binge-eating behavior.
BMI was also found to be a risk factor for BED, including among those already exhibiting binge-eating behaviors. The risk of BED onset was particularly increased among those with BMIs in the 85th percentile or higher. The transdiagnostic cognitive behavioral theory states that strict dieting and weight-control behaviors arise from an overemphasis on weight/shape/eating, which could encourage binge eating. Weight-related teasing by others could also increase the risk of different forms of disinhibited eating and binge-eating behavior among youth.
