The 1-year prevalence of schizophrenia in the United States was estimated to be 1.1% of the adult population.^{[Regier et al., 1993]}

37 Population-based studies from 25 countries that reported primary data on deaths in people with schizophrenia were examined.^{[Saha et al., 2007]}

• The median standardized mortality ratio (SMR) for all-cause mortality was 2.58.
• The median SMR for suicide was 12.86.
• The median SMRs for cardiovascular diseases, digestive diseases, infectious diseases, and respiratory diseases were 1.79, 2.38, 4.29, and 3.19, respectively.
