For each AN and BN case, we randomly selected 10 controls with no eating disorder, matched for sex, age, urbanization of residence, and year of medical visit. The percentage and frequency of health services use and costs in the year preceding and after the diagnosis of AN\/BN were compared between groups. We used generalized linear models with gamma distribution and log link function to determine the effects of age, sex, and psychiatric comorbidities on the total cost adjusting for physical comorbidities and to calculate the mean cost difference between groups by using marginal and incremental effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both individuals with AN and BN had significantly elevated healthcare utilization and costs compared to controls during the baseline and one\u2010year period after diagnosis.
