Abstract
OBJECTIVES
This study examined changes in the reporting of very low-birthweight infants in Alabama from 1974 to 1994 and the impact on perinatal mortality rates.
METHODS
Linked live birth, neonatal death, and stillbirth records of infants born weighing less than 1500 g were compared.
RESULTS
The changes in mortality over time ranged from a drop from 100% to 92% in the under-500-g group to a drop from 39% to 4% in the 1000-to 1499-g group. The percentage of total births weighing less than 500 g increased by 155%; the percentage of 1000- to 1499-g births increased by only 7%. As a result, the percentage of neonatal mortality attributable to live births below 500 g increased from 3% to 32%.
CONCLUSIONS
Increased reporting of births below 500 g has masked improvements in neonatal mortality.
摘要
目的
本研究调查了1974年至1994年阿拉巴马州极低出生体重婴儿报告情况的变化及其对围产期死亡率的影响。
方法
对体重低于1500克的活产婴儿、新生儿死亡和死产记录进行关联比较。
结果
随着时间推移，死亡率变化范围从体重不足500克组的100%降至92%，到1000至1499克组的39%降至4%。体重不足500克的总出生百分比增加了155%；1000至1499克出生的百分比仅增加了7%。因此，体重低于500克的活产婴儿导致的新生儿死亡率百分比从3%增加到了32%。
结论
体重低于500克的出生报告增加掩盖了新生儿死亡率的改善情况。
