Summary
This review found a link between depression and binge eating disorder (BED) in most studies. More rigorous research is needed to confirm this association and understand its complexities.
Area of Science:
- Psychiatry
- Clinical Psychology
- Behavioral Science
Background:
- Depression is a common mental health condition.
- Binge eating disorder (BED) is characterized by recurrent episodes of excessive food intake.
- The relationship between depression and BED requires further investigation.
Purpose of the Study:
- To systematically review existing literature on the association between depression and binge eating disorder (BED).
- To synthesize findings from studies published between 1980 and 2006.
Main Methods:
- Systematic literature review of Medline/PubMed database.
- Keywords used: "binge eating disorder and depression", "periodic binge eating and depression", "binge eating disorder", and "periodic binge eating".
- Included 14 studies: 1 cohort, 4 cross-sectional, and 9 case-control.
Main Results:
- A majority of the studies (10/14) indicated a significant association between depression and BED.
- Most studies were conducted in the United States.
- Data missingness varied considerably across studies (2.3% to 44.32%).
Conclusions:
- The reviewed literature suggests a link between depression and binge eating disorder.
- Limitations in study design were noted, highlighting the need for more robust research.
- Further carefully designed studies are necessary to establish causality and minimize biases.
