Hospitalization for anorexia nervosa in Italy.

Rivista di psichiatria, 2010, 45, 3 154 SUMMARY. Objective. This study provides: a) rates of hospitalization for anorexia nervosa (AN) in Italy in 2004-2005 period; b) an estimate of the incidence of moderate to severe hospitalizedAN in the same period among persons aged 10-19 years. Method. 9863 hospital discharges of patients aged 10-59 years with a diagnosis of AN (ICD9CM code 307.1) were extrapolated from the Italian Hospital Discharges Database. Patients aged 10-19 years, first admitted in 2004-2005, never hospitalized for AN in 2001-2003, were assumed to be a reasonable proxy of incident cases. Results. Crude rate of AN associated hospitalization was 24.2 per 100,000 person-years among women and 1.6 per 100,000 person-years among men. Estimated incidence rate of AN was 22.8 per 100,000 among women compared with 2.0 per 100,000 among men in the 10-19 years age group. Discussion. This study provides, for the first time, nationwide incidence estimates of AN in Italy.
