Abstract Objective To establish the intrauterine growth curve of twin neonates, and to investigate the intrauterine growth status of twin neonates. Methods Cross-sectional cluster sampling was performed for an on-the-spot investigation of 1 296 live twin neonates who were born in two hospitals in Shenzhen between April 2013 and September 2015. The Lambda-Mu-Sigma method was used for the curve fitting of body weight, body length, head circumference, chest circumference, and crown-rump length. Results The means and 3rd-97th percentile intrauterine growth curves for body weight, body length, head circumference, chest circumference, and crown-rump length were obtained for the 1 296 twin neonates with a gestational age of 27-40 weeks. The curve values of the 1 296 twin neonates for body weight, body length, head circumference, chest circumference, and crown-rump length were all lower than those of singleton neonates in Shenzhen that had been reported, and the difference increased with increasing gestational age. Conclusions The intrauterine growth curves for body weight, body length, head circumference, chest circumference, and crown-rump length of twin neonates with a gestational age of 27-40 weeks in Shenzhen obtained in this study can provide a reference for evaluating the intrauterine growth status of twin neonates among the current population in Shenzhen.
