Though a baby delivered at 37 weeks is still considered full-term, a new study finds that infants born in weeks 37 or 38 still have a higher death risk in the first year than those who stay in the womb until week 39. Says lead study author Dr. Uma M. Reddy, "Women need to know that all ‘term' pregnancies are not alike. If the pregnancy is uncomplicated, babies should not be delivered before 39 weeks."
