Introduction: The economic burden of binge-eating disorder (BED) in the US is not well quantified. This claims analysis compared healthcare utilization and costs of commercially insured enrollees with and without BED from the MarketScanВ Commercial Database.

Methods: Adolescents (13-17 years) and adults (≥18 years) with continuous enrollment 6 months before and 12 months following first (index) claim for BED (ICD-9-CM 307.59) were propensity score matched 1:1 to those without BED. Generalized linear models estimated adjusted healthcare costs between enrollees with and without BED.

Results: Of 1,748 adults with BED, 79.7% were female (mean age 36.3), and 18.1% and 31.1% had anxiety disorders and mood disorders, respectively. Of 702 adolescents with BED, 82.1% were female (mean age 15.2) and 21.9% and 27.8% had anxiety disorders and mood disorders, respectively. Post-matching, similar rates of anxiety disorders (18.1% vs. 18.4%; p=0.827) and mood-disorders (31.1% vs. 32.6%; p=0.364), were observed between those with and without BED. After matching, adults with BED had significantly higher post-index rates of psychiatric testing (28.8% vs 5.4%) and hospitalizations (30.7% vs 10.9; both p<0.001) than those without BED. Similar results were observed among adolescents. Both, adults (US$31,144 vs $12,625) and adolescents ($31,418 vs $8,515) with BED had significantly higher adjusted annual total costs post-index compared to those without BED.

Conclusions: This claims analysis suggest that approximately 20-30% of enrollees with BED have co-existing anxiety and mood disorders. After matching on pre-index characteristics, enrollees with BED had over 2-3 times greater costs than those without BED.
