To establish the intrauterine growth curves of neonates in Shenzhen, China and to investigate the intrauterine growth of neonates in Shenzhen.
Cross-sectional cluster sampling was performed for an on-the-spot investigation of 16 887 neonates (9 418 males and 7 469 females) with a gestational age of 27-42 weeks who were born in two hospitals in Shenzhen from April 2013 to September 2015. The Lambda Mu Sigma (LMS) method was used for the curve fitting of body weight, body length, head circumference, chest circumference, and crown-rump length.
The 3rd-97th percentile intrauterine growth curves for body weight, body length, head circumference, chest circumference, and crown-rump length were plotted for the neonates with a gestational age of 27-42 weeks who were divided into three groups (male, female, and mixed). The male neonates had significantly higher curves for the five indices than the female counterparts. The pattern and changing trend of body weight curves of these neonates were basically consistent with those in China Neonatal Network.
The percentile intrauterine growth curves for body weight, body length, head circumference, chest circumference, and crown-rump length in neonates with a gestational age of 27-42 weeks in Shenzhen which has been established can provide a reference for clinical practice in the department of neonatology.
建立中国深圳新生儿的宫内生长曲线，并研究深圳新生儿的宫内生长情况。
采用横断面整群抽样方法，对2013年4月至2015年9月在深圳两家医院出生的16887例胎龄为27 - 42周的新生儿（男9418例，女7469例）进行现场调查。采用Lambda Mu Sigma（LMS）方法对体重、身长、头围、胸围和顶臀长进行曲线拟合。
绘制了胎龄为27 - 42周的新生儿体重、身长、头围、胸围和顶臀长的第3 - 97百分位数宫内生长曲线，这些新生儿分为三组（男、女和混合组）。男新生儿这五项指标的曲线显著高于女新生儿。这些新生儿体重曲线的模式和变化趋势与中国新生儿网络中的基本一致。
已建立的深圳胎龄为27 - 42周新生儿体重、身长、头围、胸围和顶臀长的百分位数宫内生长曲线可为新生儿科临床实践提供参考。
