Abstract
Schizophrenia affects approx 1% of the population. In the United States, somewhere between 2 and 4 million people have schizophrenia (1). In addition, schizophrenia is widely considered to be the most severe and disabling of the psychiatric disorders. It is estimated that approx 30% of all hospital beds in the United States are occupied by persons with schizophrenia. In the Epidemiologic Catchment Area Study (ECA), the largest epidemiological study of psychiatric disorders, the lifetime prevalence of schizophrenic disorders (e.g., schizophrenia, schizoaffective disorder, delusional disorder) was 1.4%. However, in institutional settings, this prevalence was much higher; in mental hospitals the prevalence was 20.4%, in nursing homes it was 3.8%, and in prisons it was 6.7%. The prevalence of schizophrenia is highest in people aged 30–44 (2.3%) and lowest among those over age 65. Women were slightly more likely to have schizophrenia than men. African Americans had the highest rate at 2.1%, with Caucasians at 1.4%, and Latinos at 0.8% (2).
