The objective of the study was to investigate the risk associated with exposure to statins during pregnancy. The study collected observations from 249 statin-exposed pregnancies and 249 women not taking statins.
The study found:
(a) The statin-exposed women had a 50% increased risk of having a child with a major birth defect compared to the women not taking statins.
(b) The statin-exposed women had a 36% increased risk of having a miscarriage compared to the women not taking statins.
(c) The statin-exposed women had a 110% increased risk of having a premature birth compared to the women not taking statins.
The data from the study shows that statins increase the risk of birth defects, miscarriage and premature birth.
