Eighty morbidly obese patients who had had gastric bypass operations
were interviewed for psychiatric diagnoses using DSM-III criteria. The
lifetime prevalence of Axis I clinical psychiatric diagnoses was 47.5%,
with depressive disorders occurring in 28.7% of the total sample. No other
diagnosis exceeded a 2.5% prevalence. The authors believe there is no
evidence of an increased prevalence of major psychiatric disorder in obese
persons when strictly defined diagnostic criteria are used.Abstract Teaser
