摘要:

目的 基于全人群监测,分析上海市新生儿出生体重状况,制定适用于上海市的新生儿出生体重标准,绘制不同胎龄新生儿出生体重曲线。方法 基于上海市出生登记系统,收集2004—2023年单胎新生儿出生数据。新生儿生后12 h内测量裸身体重,胎龄由母亲末次月经、孕早期超声及出生后胎龄评分综合判定。采用基于位置、尺度、形状广义可加模型拟合胎龄24~42周不同性别新生儿体重曲线,蠕虫图和残差图分别用于局部与整体拟合诊断。依据赤池信息准则与Schwarz贝叶斯准则最小化原则,确定基于广义可加位置尺度形状模型,采用Box-Cox t分布(BCT)结合惩罚B样条(pb)平滑为最优模型,并与2022年全国标准进行比较。结果 共收集3 531 063名新生儿信息,经纳排标准筛选后,共3 338 459例新生儿纳入分析,其中男1 762 721例(52.8%),女1 575 738例(47.2%),男女比例为1.12,平均出生体重为(3 334.66±450.84)g,其中男性平均体重为(3 383.98±457.10)g女性平均出生体重为(3 279.49±437.19)g。建立上海市胎龄24~42周不同性别新生儿出生体重曲线。结果显示,随着胎龄增加,男女新生儿出生体重均持续增长,38周前增速显著,38周后增速明显放缓;男性始终高于女性,且性别差异随胎龄增大而扩大。与全国标准相比,总体趋势一致,但上海市新生儿在胎龄24~40周的体重均明显高于全国标准,而41周以后则低于全国标准。结论 本研究为制定适用于上海市新生儿的不同胎龄男、女性出生体重标准提供参考,反映上海市新生儿宫内生长水平的特征,揭示上海与全国标准在不同胎龄段的差异,为儿科临床诊断出生体重异常及评估新生儿的生长发育提供参考依据。

Abstract:

Objective To analyze the birth weight status of newborns in Shanghai based on population-wide surveillance, establish a birth weight standard applicable to Shanghai, and construct birth weight curves for newborns at different gestational ages. Method Data on singleton births from 2004 to 2023 were collected from the Shanghai Birth Registration System. Newborns were weighed naked within 12 hours after birth, and gestational age was determined based on the mother's last menstrual period, first-trimester ultrasound, and postnatal gestational age assessment. A generalized additive model for location, scale, and shape (GAMLSS) was used to fit birth weight curves for newborns of both sexes at 24-42 weeks of gestation. Worm plots and residual plots were employed for local and global fit diagnostics, respectively. The optimal model, determined by minimizing the Akaike Information Criterion (AIC) and Schwarz Bayesian Criterion (SBC), was the Box-Cox t distribution combined with penalized B-spline smoothing. The results were compared with the 2022 national standard. Result A total of 3,531,063 newborns were initially included, and after applying inclusion/exclusion criteria, 3,338,459 newborns were analyzed : males 1,762,721 (52.8%) and females 1,575,738 (47.2%), with a male-to-female ratio of 1.12. The mean birth weight was 3334.66 ± 450.84 g (3 383.98 ± 457.10 g for males and 3 279.49 ± 437.19 g for females). Birth weight curves for newborns of both sexes at 24-42 weeks of gestation were established for Shanghai. The results showed that birth weight increased continuously with gestational age for both sexes, with significant growth before 38 weeks and a marked slowdown thereafter. Males consistently had higher birth weights than females, and the sex-based difference widened with advancing gestational age. Compared with the national standard, the overall trend was similar, but Shanghai newborns had significantly higher birth weights at 24-40 weeks, whereas weights at ≥41 weeks were lower than the national standard. Conclusion This study establishes sex-specific birth weight standards for newborns in Shanghai at different gestational ages, reflecting the characteristics of intrauterine growth levels in Shanghai. It highlights differences between Shanghai and national standards across gestational age ranges, providing a reference for clinical diagnosis of abnormal birth weight and assessment of neonatal growth and development.
