The \u2018relative risk\u2019 of admission to a psychiatric hospital with a psychotic illness was extremely high in the first 30 days after childbirth, particularly in primiparae, suggesting that metabolic factors are involved in the genesis of puerperal psychoses. However, being unmarried, having a first baby, Caesarian section and perinatal death were all associated with an increased risk of psychiatric admission or contact, or both, suggesting that psychological stresses also contribute to this high psychiatric morbidity. Women with a history of manic depressive illness, manic or depressive, had a much higher risk of psychiatric admission in the puerperium than those with a history of schizophrenia or depressive neuroses, and the majority of puerperal admissions met Research Diagnostic Criteria for manic or depressive disorder. Probably, therefore, puerperal psychoses are manic depressive illnesses and unrelated to schizophrenia.<\/jats:p>","DOI":"10.1192\/bjp.150.5.662","type":"journal-article","created":{"date-parts":[[2008,8,12]],"date-time":"2008-08-12T19:43:23Z","timestamp":1218570203000},"page":"662-673","source":"Crossref","is-referenced-by-count":882,"title":["Epidemiology of Puerperal Psychoses"],"prefix":"10.1192","volume":"150","author":[{"given":"R.
