Study description

Second generation antipsychotics have largely replaced first generation antipsychotics but little is known about their safety during pregnancy. This is a population based study based on national register data in Finland. Data from the National Birth Register, the Register of Congenital Malformations, and the Drug Prescription Register have been linked through years 1996-2012 in the Drugs and Pregnancy project, and data in this study are extracted from the Drugs and Pregnancy project database. The data include all births (live and still births), pregnancy terminations due to major congenital anomaly, and information on drug purchases during pregnancy and 3 months before pregnancy. There are appr. 55,000-60,000 births per year in Finland, and we expect to have a baseline study population with appr. 1 mil. pregnancies. Appr. 0.2-0.6% of pregnant women during the study period used antipsychotics and we expect to include appr.2,000 pregnancies exposed to second generation antipsychotics. The primary aims of the study are i.) to assess the risk of major congenital anomalies after first trimester exposure to second generation antipsychotics and ii.) to investigate the prevalence of other perinatal outcomes, including large for gestational age, preterm birth, low birth weight, and perinatal mortality after continuous exposure. The exposed group is compared i) to women and their offspring exposed to first generation antipsychotics during the period of theree months prior to pregnancy until the end of pregnancy (to control for maternal illness), and ii) to unexposed women. Logistic regression is used to evaluate associations between exposure and outcome, and covariates to be considered include year of birth, mother's age, parity, tobacco use, prepregnancy diabetes, use of other psychiatric drugs and use of drugs classified as potentially harmful. The results will provide important information on the safety of second generation antipsychotics during pregnancy.
