目的：我们的目的是分析低出生体重儿的区域化的时间趋势和区域化与新生儿死亡率下降之间的关联的时间趋势。研究设计：出生体重为500至2000克的69,452名新生儿的数据来自出生证明的电子文件。医院的围产服务分为1级，2级，3级（3级是指三级转诊中心）。结果：从1968年到1994年，在三级医院外出生的可能性下降，体重500至1500 g的婴儿平均每年下降24%，体重1501至2000 g的婴儿平均每年下降20%。1974年以后，在三级医院出生的婴儿死亡风险较低。这种关联的强度在20世纪90年代有所增强。结论：在北卡罗来纳州，婴儿体重的比例
OBJECTIVE: Our purpose was to analyze trends across time in the regionalization of low-birth-weight births and time trends for the association between regionalization and decreased neonatal mortality.STUDY DESIGN: Data on 69,452 neonates with birth weights of 500 to 2000 g were obtained from electronic files of birth certificates. Hospitals' perinatal services were classified as level 1, 2, or 3 (level 3 refers to tertiary referral centers).RESULTS: The likelihood of birth outside revel 3 hospitals decreased from 1968 to 1994, with an average annual decrease of 24% for infants weighing 500 to 1500 g and 20% for infants weighing 1501 to 2000 g. After 1974, birth in a hospital with level 3 services was associated with a lower risk of dying. The strength of this association increased in the 1990s.CONCLUSIONS: In North Carolina the proportion of infants weighing
