EU PAS Register NumberEUPAS7994
Official titleAsthma medication during pregnancy : a cohort study in EFEMERIS
Study title acronym
Study typeObservational study
Brief description of the studyAsthma affects around 8% of pregnant women. Studies show that women experience changes in prescriptions for asthma medications during pregnancy, maybe because of concerns about their possible adverse effects on the fetus. The objective of the study is to describe asthma medications before and during pregnancy in France and to assess the possible association between asthma medications and adverse pregnancy outcomes.
Women from EFEMERIS, a French database including prescribed and dispensed reimbursed drugs during pregnancy and pregnancy outcomes, who delivered between July 1, 2005 and December 31, 2012 will be included. Women with at least 2 dispensations for any asthma medication (ATC code R03) from the 30 days prior to conception through their date of delivery will be considered asthmatic. First, a description of prescription of asthma medications will be made. Second, we will compare pregnancy outcomes and newborn health between asthmatic and non-asthmatic women.
