Abstract
Inpatient-treated prevalence of the 3 mental illnesses most often requiring inpatient treatment (schizophrenia, alcoholism and affective disorders) were compared to social class in a suburban area. Rates were developed for the total population, including those living in domiciliary care, those living in households only and 1st-admission patients living in households. Log-linear models supported the finding that low socioeconomic status was related to a high prevalence of alcoholism and affective disorders. Socioeconomic status was not related to the prevalence of schizophrenia among those living in households or among 1st-admission patients living in households.
