Which of the following eating disorders is most common?

Question

BlackTom AI · Accepted Answer

Binge Eating Disorder (BED) has the highest lifetime prevalence among the listed eating disorders.

1. Relevant knowledge points and concepts
- Anorexia nervosa, bulimia nervosa, and binge eating disorder are distinct DSM-defined eating disorders with different core behaviors: restrictive intake and low weight for anorexia; bingeing with compensatory behaviors (purging, fasting, excessive exercise) for bulimia; recurrent binge eating episodes without regular compensatory behaviors for BED.
- Epidemiology (prevalence) is the key concept for “most common.”

2. Complete reasoning process step by step
- Determine which disorder occurs in the population most frequently by comparing typical lifetime prevalence estimates from epidemiological studies.
- Use representative prevalence ranges commonly reported in clinical literature.

3. Intermediate steps / prevalence comparison (typical ranges)
- Binge Eating Disorder: commonly reported lifetime prevalence in general adult samples is roughly around 1.5–3% (and higher in some community samples), making it the most frequently observed of the three.
- Bulimia Nervosa: lifetime prevalence estimates are lower, commonly around 0.5–2% depending on sample and criteria.
- Anorexia Nervosa: lifetime prevalence is lowest, typically estimated around 0.3–1% in many populations.
- Compare these: BED (~1.5–3%) > Bulimia (~0.5–2%) > Anorexia (~0.3–1%).

4. Why the correct answer is correct
- Because the typical population prevalence of BED is higher than that of bulimia and anorexia, BED is the most common among the options. Many large-scale surveys and meta-analyses report BED as the most prevalent clinically recognized eating disorder.

5. Why other options are incorrect
- “Anorexia Nervosa”: incorrect because its prevalence is substantially lower than BED.
- “Bulimia Nervosa”: incorrect because bulimia’s prevalence is generally lower than BED’s.
- “Anorexia Nervosa and Bulimia Nervosa equally”: incorrect because the two disorders do not have equal prevalence and both are generally less common than BED.

6. Conclusion confirming the final answer
- Based on prevalence data and comparison, the correct choice is Binge Eating Disorder, which matches the provided answer.
