Key Points: Question: Is benzodiazepine use during pregnancy associated with miscarriage, taking into account both measured and unmeasured confounding factors? Findings: In this case-time-control study, benzodiazepine use during pregnancy was associated with an increased risk of miscarriage, even after accounting for unmeasured confounders, including those related to genetics and the family environment. Meaning: The observation of an increased risk of miscarriage associated with benzodiazepine use during pregnancy suggests that benzodiazepines should only be used after a thorough evaluation of the potential benefits and risks for both the mother and child. This case-time-control study evaluates the association between benzodiazepine use during pregnancy and risk of miscarriage. Importance: Benzodiazepine use during pregnancy has raised significant concerns due to the potential harmful effects of this drug class on neonates. Studies on the association between benzodiazepine use and the risk of miscarriage are limited. Objective: To quantify the risk of miscarriage associated with benzodiazepine use during pregnancy after controlling for unmeasured confounders and exposure time trends. Design, Setting, and Participants: This was a nationwide, population-based case-time-control study using Taiwan's National Birth Certificate Application database and the National Health Insurance database. Pregnancies resulting in miscarriage between 2004 and 2018 were included in the case group and were 1:1 matched with exposure time-trend control individuals using disease risk score, considering demographic characteristics and prepregnancy comorbidities. Data were analyzed from August 2022 to March 2023. Exposures: Discordant exposures to benzodiazepines during risk period (1-28 days before miscarriage) and 2 reference periods (31-58 days and 181-208 days before the last menstrual period) were compared for each pregnancy. Main Outcomes and Measures: Miscarriage was defined as any pregnancy loss occurring between the first prenatal care visit (usually 8 weeks) and the 19th completed week of pregnancy. Results: This study comprised a total of 3 067 122 pregnancies among 1 957 601 women, 136 134 of which (4.4%) resulted in miscarriage. The mean (SD) age of the study population was 30.61 (5.91) years. The use of benzodiazepines during pregnancy was associated with an increased risk of miscarriage (odds ratio [OR], 1.69; 95% CI, 1.52-1.87), and consistent findings were observed across multiple sensitivity analyses considering different time windows and accounting for misclassification. In subgroup analyses, an increased risk of miscarriage was associated with each commonly used individual benzodiazepine, ranging from case-time-control ORs of 1.39 (95% CI, 1.17-1.66) for alprazolam to 2.52 (95% CI, 1.89-3.36) for fludiazepam. Conclusions and Relevance: This nationwide case-time-control study revealed an increased risk of miscarriage associated with benzodiazepine use during pregnancy after accounting for measurable confounders, and results were unlikely to be due to unmeasured confounding. These findings underscore the necessity for health care professionals to meticulously balance the risk-benefit ratio when considering the use of benzodiazepines to treat psychiatric and sleep disorders during pregnancy.
