Résumé

Bipolar disorder (BD) is associated with elevated rates of eating disorders (EDs), but the nature and impact of specific ED features are unclear. This study sought to identify which ED features are common in BD, and whether these relate to quality of life (QoL) impairment and body mass index (BMI). A clinical sample of 73 adults with BD completed self-report measures of health, ED features, emotion regulation ability, impulsivity, and QoL. Binge eating (45%), excessive dietary restriction (39%), overvaluation of weight/shape (51%), purging (16%) and driven exercise (27%) were common, and associated with a poorer clinical picture, including poorer QoL and poorer emotion regulation. Furthermore, regular binge eating episodes explained a significant proportion of variance in QoL impairment after controlling for other significant predictors. The best predictors of BMI were number of medical conditions, impulsivity and positive beliefs about binge eating. ED features that may not meet criteria for a fully diagnosable ED - particularly overvaluation of weight/shape and binge eating - warrant greater attention, as they may still significantly worsen QoL. Future research should focus on modifying existing psychological interventions to better target ED features among individuals with BD and thereby improve clinical outcomes.

BACKGROUND UNASSIGNED
Bipolar disorder (BD) is associated with elevated rates of eating disorders (EDs), but the nature and impact of specific ED features are unclear.
AIMS UNASSIGNED
This study sought to identify which ED features are common in BD, and whether these relate to quality of life (QoL) impairment and body mass index (BMI).
METHOD UNASSIGNED
A clinical sample of 73 adults with BD completed self-report measures of health, ED features, emotion regulation ability, impulsivity, and QoL.
RESULTS UNASSIGNED
Binge eating (45%), excessive dietary restriction (39%), overvaluation of weight/shape (51%), purging (16%) and driven exercise (27%) were common, and associated with a poorer clinical picture, including poorer QoL and poorer emotion regulation. Furthermore, regular binge eating episodes explained a significant proportion of variance in QoL impairment after controlling for other significant predictors. The best predictors of BMI were number of medical conditions, impulsivity and positive beliefs about binge eating.
CONCLUSIONS UNASSIGNED
ED features that may not meet criteria for a fully diagnosable ED - particularly overvaluation of weight/shape and binge eating - warrant greater attention, as they may still significantly worsen QoL. Future research should focus on modifying existing psychological interventions to better target ED features among individuals with BD and thereby improve clinical outcomes.
