2007-2018年浙江省义乌市新生儿出生体重变化趋势比较分析

Analysis on change trend of newborn birth weight in Yiwu, 2007–2018

  • 摘要:
    目的分析2007—2018年浙江省义乌市新生儿出生体重变化趋势,并与不同标准进行比较,制订和更新适合目标人群的新生儿出生体重曲线。
    方法利用义乌市妇幼保健信息平台的数据,提取2007年1月至2018年6月记录的新生儿出生体重,分析出生体重变化趋势以及低出生体重儿和巨大儿发生率变化情况。 采用LMS方法计算出胎龄别出生体重百分位数参考值,运用GAMLSS模型绘制出生体重曲线;将本研究的胎龄别出生体重百分位数参考值与国内外研究进行对比。
    结果本研究共纳入了68 358名新生儿,其中男、女婴的平均出生体重分别为3 373 g和3 257 g。 男、女婴早产的比例分别为6.01%和5.04%,男婴早产比例显著高于女婴。 低出生体重儿和巨大儿分别占3.84%和7.43%。 出生胎龄33 ~ 41周的男婴出生体重均显著大于女婴出生体重。 随着出生胎龄的增长,出生体重也相应增加。 男婴出生胎龄为37 ~ 41周的胎龄别出生体重均大于2015年全国标准;33 ~ 41周的胎龄别出生体重均大于INTERGROWTH-21st的百分位数参考值。女婴出生胎龄为38 ~ 41周的胎龄别出生体重均大于2015年全国标准;33、35 ~ 41周的胎龄别出生体重均大于INTERGROWTH-21st 的百分位数参考值。
    结论2007—2018年义乌市男婴出生体重呈逐年下降趋势,女婴出生体重随年份变化趋势不显著。 本次研究提出了义乌市新生儿胎龄别出生体重参考值,分性别绘制了出生体重曲线参考。

     

    Abstract:
    ObjectiveTo analyze the change trend of newborn birth weight in Yiwu, Zhejiang province, establish and revise the percentile curve of gestational age specific birth weight of newborns and compare it with different birth weight standards.
    MethodsThe data from the Yiwu Maternal and Child Health Information Platform were used to analyze the gestational age specific birth weight, rate of low birth weight and macrosomia in newborns. The LMS method was used to calculate the reference values for percentiles of gestational age specific birth weight. The GAMLSS model was used to draw the birth weight curve. The reference percentile value of the birth weight of this study was compared with domestic and foreign studies.
    ResultsA total of 68 358 newborns were included in this study. The average birth weights in male newborns and female newborns were 3 373 g and 3 257 g, respectively. The rates of preterm birth in male newborns and female newborns were 6.01% and 5.04%, respectively. The rate of preterm birth in baby boys was significantly higher than that in baby girls. The rates of low birth weight and macrosomia were 3.84% and 7.43%, respectively. The birth weight of baby boys at gestational age 33–41 weeks was significantly higher than that of female newborns at same gestational age. The birth weight increased with gestational age. The birth weight of baby boys was higher than 2015 national standard at gestational age 37–41 weeks and higher than the reference percentile value of INTERGROWTH-21st study at gestational age 33–41 weeks. The birth weight of female newborns was higher than the 2015 national standard at gestational age 38-41 weeks and higher than the reference percentile value of INTERGROWTH-21st study at gestational age 33, 35–41 weeks.
    ConclusionDuring 2007–2018, the birth weight of baby boys in Yiwu showed a decrease with year, and the birth weight of female newborns showed no obvious change. The gender specific birth weight curves of newborns were drawn.
