Abstract：Objective To carry out the intrauterine growth evaluation of neonates, and establish intrauterine growth curves of singleton neonates in different gestational age (GA) among primiparity and multiparity. Methods We evaluated and classified the intrauterine growth of 324 521 multiparous, primiparous, and mixed neonates from Shenzhen, Chongqing, Haikou, Guangzhou, Changsha, Chengdu, Quanzhou, Liuzhou, and Guilin cities in China from 2017 to 2020. We also revealed the characteristics of intrauterine growth higher level in multiparity than that that in primiparity. A total of 16 852 live singleton neonates in 28~42 weeks of GA among primiparity and multiparity from Shenzhen City were measured at birth by cluster sampling from April 2013 to September 2015 in this cross sectional study. We established intrauterine growth curves of singleton neonates among primiparity and multiparity. Results The classification and evaluation results of intrauterine growth grade for 324 521 neonates in 9 maternal and child health care hospitals of China showed the orders in the characteristics were multiparous neonates, mixed neonates, and primiparous neonates. We created the intrauterine growth 3rd~97th percentile curves of body weight, body length, crown-rump length, head circumference, and chest circumference of 16 852 singleton neonates in 28~42 weeks of GA among primiparity and multiparity in Shenzhen, China. The level of above 5 indexes of multiparous neonates was higher than that of primiparous neonates. The 10th, 50th and 90th curves of body weight for multiparous singleton neonates were higher than those of Shenzhen singleton neonates in 2015, while the 10th, 50th and 90th curves of body weight for primiparous singleton neonates were lower than those of Shenzhen singleton neonates in 2015. Conclusion The level of intrauterine growth evaluation of neonates in multiparity was higher than that in primiparity in Chinese nine cities. We created the intrauterine growth 3rd~97th percentile curves of body weight, body length, crown-rump length, head circumference, and chest circumference of singleton neonates in 28~42 weeks of GA among primiparity and multiparity in Shenzhen, China. It provided the standard about above 5 indexes of intrauterine growth evaluation for multiparous neonates and primiparous neonates. The curve level of above 5 indexes of multiparous neonates was higher than that of primiparous neonates.
