Abstract

Intrauterine growth of live-born infants between 28 and 42 weeks of gestation has been measured by birth weight. All live-born infants in Miyagi prefecture where is situated at the middle part of Japan were 31,534 from February, 1978 to January, 1979. Out of the 31,534 live-born infants, there were 11,025 cases whose records were incomplete, because of uncertainty concerning duration of pregnancy. So, we investigated 19,509 live-born infants. Most of them were born at term (37 to 41 weeks of gestation). Premature delivery rate was 3.36% and postterm delivery rate was 3.78%. Finally, we made the intrauterine growth curves derived from 19,509 live-born infants at each week of gestation and weights for 10th, 50th and 90th percentile.

摘要

通过出生体重来衡量妊娠28至42周之间活产婴儿的宫内生长情况。位于日本中部的宫城县，在1978年2月至1979年1月期间共有31,534例活产婴儿。在这31,534例活产婴儿中，有11,025例记录不完整，原因是妊娠时长不确定。因此，我们对19,509例活产婴儿进行了调查。其中大多数婴儿为足月出生（妊娠37至41周）。早产率为3.36%，过期产率为3.78%。最后，我们绘制了19,509例活产婴儿在妊娠各周的宫内生长曲线以及第10、第50和第90百分位数的体重曲线。
