Study Details

Study Description

Brief Summary

This is a nationwide cohort study to assess maternal and neonatal outcomes following exposure to benzodiazepines during pregnancy.

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.

Arms and Interventions

Arm Intervention/Treatment
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
Exposure to benzodiazepine during early pregnancy

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

Drug: Benzodiazepine
Exposure to benzodiazepine during early pregnancy

Outcome Measures

Primary Outcome Measures

  1. 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.
