Termination of Pregnancy and Psychiatric Morbidity

Abstract

BackgroundWe investigated whether reported psychiatric morbidity was increased after termination of pregnancy compared with other outcomes of an unplanned pregnancy.MethodThis was a prospective cohort study of 13 261 women with an unplanned pregnancy. Psychiatric morbidity reported by GPs after the conclusion of the pregnancy was compared in four groups: women who had a termination of pregnancy (6410), women who did not request a termination (6151), women who were refused a termination (379), and women who changed their minds before the termination was performed (321).ResultsRates of total reported psychiatric disorder were no higher after termination of pregnancy than after childbirth. Women with a previous history of psychiatric illness were most at risk of disorder after the end of their pregnancy, whatever its outcome. Women without a previous history of psychosis had an apparently lower risk of psychosis after termination than postpartum (relative risk RR = 0.4, 95% confidence interval CI = 0.3–0.7), but rates of psychosis leading to hospital admission were similar. In women with no previous history of psychiatric illness, deliberate self-harm (DSH) was more common in those who had a termination (RR 1.7, 95%CI 1.1–2.6), or who were refused a termination (RR 2.9, 95%CI 1.3–6.3).ConclusionsThe findings on DSH are probably explicable by confounding variables, such as adverse social factors, associated both with the request for termination and with subsequent self-harm. No overall increase in reported psychiatric morbidity was found.
