Children whose mothers took multiple courses of corticosteroids during their pregnancy to prevent preterm birth were no more likely to die or have a neurodevelopmental disability at age 5 than those in the single-course group, according to a Canadian study. Despite similar rates of death or disability in both single- and multiple-course groups, researchers said that multiple courses of prenatal steroids should not be recommended due to "lack of strong conclusive evidence of short-term or long-term benefits." The findings appear in the journal JAMA Pediatrics.
