Outcome Measures

Primary Outcomes (1)

  • Risk of congenital malformations

    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.

    from the birth date until up to 8 years, death, or study end date (Dec 31, 2019)

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

Drug: Benzodiazepine

Interventions

Exposure to benzodiazepine during early pregnancy

Pregnant women with exposure to benzodiazepinesPregnant women without exposure to benzodiazepines
