Twelve per cent of the 847 women who delivered in one hospital prior to implementation of the North Carolina Prematurity Prevention Program had low-birthweight births compared with 9.5 per cent of the 748 women who delivered during the program. Controlling for known risk factors, both low- and very-low birthweight births among Whites (Odds Ratio 2.0 and 3.7 respectively) and very-low-birthweight births among Blacks (OR 2.9) were reduced.
在北卡罗来纳州早产预防计划实施之前,在一家医院分娩的847名妇女中有12%生下了低体重儿,而在该计划实施期间分娩的748名妇女中这一比例为9.5%。在控制了已知风险因素后,白人中的低体重儿和极低体重儿出生情况(优势比分别为2.0和3.7)以及黑人中的极低体重儿出生情况(优势比为2.9)都有所减少。
