【目的】了解上海市卢湾区活产儿的胎龄别出生体重情况,为胎儿生长发育状况的监测和评价提供参考依据。【方法】利用上海市卢湾区疾病预防控制中心出生监测系统对2005—2007年户籍活产婴儿的出生体重进行统计分析。【结果】上海市卢湾区活产婴儿的出生体重随着胎龄的增加而增长,增长最快的为33～37周,41周后出现下降。35周后男婴出生体重高于女婴,经产妇生育的活产儿体重高于初产妇;与同时代整个上海地区相比较,出生体重基本接近。【结论】上海市卢湾区活产儿的出生体重与整个上海市水平较接近,胎龄别出生体重的分布特点相似,有关部门应进一步探索制定新的出生体重标准。
【Objective】 To understand the gestational age and birth weight of live births in Luwan District of Shanghai and to provide reference for the monitoring and evaluation of fetal growth and development status. 【Method】 The birth monitoring system of birth control was adopted in Luwan District of Shanghai for statistical analysis of the birth weight of live births in 2005-2007. 【Results】 The birth weight of live-born infants in Luwan District of Shanghai increased with the increase of gestational age, the fastest growing was from 33 to 37 weeks and decreased after 41 weeks. After 35 weeks, the birth weight of the male infant was higher than that of the female infant. The live birth weight of the male childbirth was higher than that of the first born women. Compared with the whole Shanghai area in the same period, the birth weight was basically similar. 【Conclusion】 The birth weight of live births in Luwan District of Shanghai is similar to that of the whole Shanghai city. The distribution characteristics of birth weight at gestational age are similar. Relevant departments should further explore and formulate new birth weight standards.
