U.S. preterm births fall to 15-year low, still worst in developed world

By Sharon Begley NEW YORK (Reuters) – The rate of preterm births in the United States dropped to a 15-year low of 11.5 percent in 2012, according to a report released on Friday, but the country still came in dead last among industrialized nations on this measure of infant health. The rate reflects six straight years of declines, possibly due to factors such as a drop in smoking among women of childbearing age, said the March of Dimes, the nonprofit group that produced the report. The improvement comes during an acrimonious, partisan debate in Congress about health insurance centered on President Barack Obama’s healthcare reform law. The Affordable Care Act requires all insurance plans to cover maternity care, spreading the cost of healthy pregnancies across society.
