| Abstract: |
从1982年1~12月北京市东城区交道口等七个地段共出生3，153名婴儿，记录体重及孕周者2，575名。254例仅记录体重，无孕周，二组共计2，819名，占全部新生儿的89.71%。根据2，575例的完整资料分析，新生儿平均体重为3284.2±9.7克，40孕周婴儿平均体重为3313.2±13.7克，仅记录体重而无孕周的254例，平均体重为3290.9±37.8克，与记录完整者相近。
低体重儿（体重≤2500克）占5%，该数字低于1979年WHO公布的亚洲、欧洲及北美的低体重儿百分数（7~20%）。无一例产妇年龄在20岁以下，所有产妇在产前均获得较好的卫生保健。 |

Among them 2,575 had complete records of weight at birth and date of regestration, and 254 had incomplete records noting down the birth weight only.Altogether, these 2 groups covered 89.71% of all the cases under Study The infants of the former group were found to have an average weight of 3284.2±9.1 grams birth, while those of the later group an average weight of 3290.9±37.8 grams at birth.There was no significant difference in birth weight between these two groups. In addition, the average weight of imfants born at the 40th week of pregnancy was found to be 3313.2 ±13.7 grams.
