Gender differences in weight bias internalisation and eating pathology in overweight individuals

The present study explores gender differences in weight bias internalisation, measured by the Weight Bias Internalisation Scale (WBIS), and eating pathology (EDE-Q). Participants were 644 overweight and obese (mean body mass index [BMI]: 34.51 ± 7.58) adults who completed a survey that included measures of disordered eating behaviours and attitudes. Women reported higher levels of weight bias internalisation, shape/weight concern, and more weight cycling than men. Among women, weight bias internalisation was more strongly associated with disordered eating-related attitudes and depressive symptoms than in men. In contrast, among men, weight bias internalisation was associated with higher BMI and more objective and subjective binge episodes than in women. In overweight individuals, there are gender differences in the relationship between weight bias internalisation and eating pathology. These attitudinal and behavioural differences have important implications for clinicians treating overweight individuals.
