2010—2019年绍兴市新生儿出生体重变化趋势分析

Trend analysis of birth weight change among newborns in Shaoxing city from 2010 to 2019

目的了解2010—2019年绍兴市活产新生儿出生体重的变化趋势,更好地指导绍兴地区围生期保健工作。方法利用绍兴市妇幼保健院信息系统,应用SPSS 19.0软件统计,回顾性分析2010—2019年在绍兴市妇幼保健院产科分娩的活产新生儿出生体重情况。结果110542例活产新生儿平均出生体重(3254.98±531.78)g,男婴平均出生体重大于女婴(t=31.303,P<0.01)。在孕周41周前,平均出生体重随着孕周的延长而增长。低出生体重发生率7.1%,女婴低出生体重发生率高于男婴(χ^(2)=29.930,P<0.01);巨大儿发生率5.4%,男婴巨大儿发生率明显高于女婴(χ^(2)=369.866,P<0.01)。结论新生儿出生体重整体处于上升趋势,低出生体重发生率仍处于较高水平,控制新生儿出生体重在适宜范围,预防早产,提高出生人口质量,仍是孕期保健工作重点。

Objective To understand the trend of birth weight among live newborns in Shaoxing city from 2010 to 2019 and to better guide the perinatal health care work in this area.Method Based on the data of Shaoxing Maternal and Child Health Hospital and SPSS 19.0,a retrospective analysis was made of the birth weight of live newborns in our hospital from 2010 to 2019.Results The average birth weight of 110542 live newborns was(3254.98±531.78)g,and the average birth weight of male newborns was greater than that of female newborns(t=31.303,P<0.01).Before the 41st week of gestation,the average birth weight increased with the extension of the gestational week.The incidence of low birth weight was 7.1%,and that of female newborns was higher than that of male newborns(χ^(2)=29.930,P<0.01).The incidence of macrosomia was 5.4%,and that of male newborns was higher than female newborns(χ^(2)=369.866,P<0.01).Conclusion The birth weight of newborns is on the whole rising,and the incidence of low birth weight is still at a relatively high level.Keeping the birth weight of newborns in an appropriate range,preventing premature birth,and improving the quality of the birth population are still the key points of health care during pregnancy.
