Premature or preterm births are defined as live births before a woman completes thirty-seven weeks of pregnancy. A new study found that about fifteen million babies were born prematurely around the world in twenty-ten. The study was the first of its kind, and shows that the problem exists in poor countries as well as in wealthy ones.早产是指妇女在怀孕37周之前的生产。一项新研究表明，2010年全世界约有1500万婴儿早产。该研究是这方面的第一项研究，它还表明，贫穷国家和富裕国家一样存在这一问题。
