Abstract

OBJECTIVE:

To compare four subgroups of adults with overweight/obesity: those with binge-eating disorder (BED) only, food addiction (FA) only, both BED + FA, and neither.

METHODS:

For this study, 502 individuals with overweight/obesity (body mass index >25 kg/m(2) ) completed a Web-based survey with established measures of eating and health-related behaviors. Most were female (n = 415; 83.2%) and White (n = 404; 80.8%); mean age and body mass index were 38.0 (SD = 13.1) years and 33.6 (SD = 6.9) kg/m(2) , respectively.

RESULTS:

Among 502 participants with overweight/obesity, 43 (8.5%) met BED criteria, 84 (16.6%) met FA criteria, 51 (10.1%) met both BED + FA criteria, and 328 (64.8%) met neither (control). The three groups with eating pathology (BED, FA, and BED + FA) had significantly greater disturbances on most measures (eating disorder psychopathology, impulsivity, and self-control) than the control group, while the FA and BED + FA groups reported significantly higher depression scores relative to the control group. The three eating groups did not differ significantly from each other.

CONCLUSIONS:

In this online survey, of those with overweight/obesity, nearly one third met criteria for BED, FA, or BED + FA, and these forms of disordered eating were associated with greater pathology relative to individuals with overweight/obesity without BED and FA. Future research should examine whether the presence of BED, FA, or co-occurring BED + FA requires tailored interventions in individuals with overweight or obesity.
