Key Takeaways
- Bulimia nervosa lifetime prevalence estimates in the NCS-R are approximately 1.0% overall across the population (aggregate prevalence).
- In the U.S., the median age of onset for bulimia nervosa is often reported in the mid-teens to early adulthood; clinical review provides an onset range and mean/median figures.
- Among adolescents in epidemiologic surveys, bulimia nervosa prevalence estimates vary by study design but are typically under 1%—with numeric prevalence values reported in population studies.
- DSM-5 specifies binge eating episodes occur at least once per week for 3 months in bulimia nervosa; the criterion includes the same numeric threshold.
- A diagnostic assessment study reports inter-rater reliability metrics (e.g., kappa statistics) for bulimia nervosa diagnosis when using structured interviews (numeric agreement coefficients).
- A study of eating disorder screening reported sensitivity and specificity numeric values for bulimia nervosa identification using screening tools (quantified diagnostic performance).
- In a large pooled analysis, approximately 50%–60% of people with bulimia nervosa show remission over time (range reported across studies).
- In treatment studies, effect sizes are reported numerically (e.g., standardized mean differences) for reductions in bulimia nervosa symptoms; the meta-analysis provides numeric effect measures.
- A Cochrane review includes a numeric count of included studies and participants for bulimia nervosa interventions (review sample sizes).
- NICE NG69 provides numeric recommendation details about access to specialist care within a timeframe (e.g., within weeks) for people with eating disorders, including bulimia nervosa.
- The APA Practice Guideline for the Treatment of Patients With Eating Disorders (3rd ed.) recommends CBT as a first-line approach for bulimia nervosa (practice recommendation).
- The British Association for Psychopharmacology guideline states that SSRIs (including fluoxetine) should be considered for bulimia nervosa (recommendation).
- A 2019 Global Burden of Disease study reported that eating disorders (including bulimia nervosa as part of eating disorder category) contributed measurable DALYs; the study provides quantitative DALY estimates for eating disorders overall.
- In the Global Burden of Disease study, eating disorders contribute a quantifiable share of mental health and behavioral disorders burden; the results include numeric DALYs for eating disorder categories.
- The WHO World Health Statistics report includes numeric estimates on mental health and substance use and discusses eating disorders within mental health burden framing (quantitative health statistics context).
Bulimia affects about 1% lifetime, and CBT and fluoxetine can significantly improve symptoms and remission rates.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
