Objective: To establish the intrauterine growth curves of neonates in Shenzhen, China and to investigate the intrauterine growth of neonates in Shenzhen.
Methods: 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.
Results: 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.
Conclusions: 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.
目的: 制定深圳新生儿宫内生长曲线，了解深圳新生儿宫内生长水平。
方法: 采用横断面时间段整群取样调查方法，于2013年4月至2015年9月在深圳市两家医院完成了胎龄27~42周活产单胎新生儿16 887例（男9 418例，女7 469例）现场调查。体重、身长、头围、胸围、顶臀长5项指标曲线拟合应用Lambda Mu Sigma（LMS）法。
结果: 制定了深圳胎龄27~42周新生儿（男、女、性别混合）三分组体重、身长、头围、胸围、顶臀长5项指标宫内生长第3~97百分位曲线。上述5项曲线男性明显高于女性。该组新生儿体重曲线形态及变化趋势与中国新生儿协作网曲线基本一致。
结论: 该研究制定的深圳胎龄27~42周新生儿体重、身长、头围、胸围、顶臀长宫内生长百分位曲线可为新生儿科医生临床实践工作提供参考。
