Detailed Description
Benzodiazepines are widely used in pregnant women; however, their safety on congenital malformations in a real-world setting is still uncertain. We aimed to assess the association between benzodiazepine use in early pregnancy and the risk of congenital malformations. We will conduct a retrospective nationwide cohort study using the Health Insurance Review and Assessment (HIRA) database of South Korea, which covers the entire South Korean population.

Pregnant women with exposure to benzodiazepines Women who gave birth during 2011-2018, were aged 20-45 years and were filled at least one benzodiazepine prescription during the first trimester (first 90 days of pregnancy). |
Drug: Benzodiazepine

Pregnant women without exposure to benzodiazepines Women who gave birth during 2011-2018, were aged 20-45 years and did not fill a benzodiazepine prescription during the 3 months before the pregnancy onset through the end of the first trimester |

Outcome Measures
Primary Outcome Measures
- Risk of congenital malformations [from the birth date until up to 8 years, death, or study end date (Dec 31, 2019)]
Overall congenital malformations and organ-specific congenital malformations in infants, which are confirmed by diagnostic records in the HIRA database. All infants were followed up for at least 1 year.
