Abstract：Objective To establish the Quetelet index (QI) of singleton neonates with different gestational age (GA) so as to provide reference data for evaluating enrichment degree of neonates at birth in Shenzhen. Methods A cross-sectional cluster sampling was performed in two hospitals from April 2013 to September 2015. Body weight, body length, crown-rump length, head circumference and chest circumference of 16,887 singleton neonates (including 9,418 boys and 7,469 girls) with different GA at birth were measured on the spot, and then the QI of singleton neonates with different GA was created. Results We plotted the QI mean values and 3rd-97th percentile intrauterine growth curves of singleton neonates withGA of 27-42 weeks and from three groups of male, female, and both sexes in Shenzhen in 2015. Male and female neonates with GA of 27 weeks had the lowest QI value, which gradually increased with the increasing GA and reached the highest at 42 weeks of GA. The value of QI 50th curve at each gestational weekforneonates with GA of 27-42 weeks was higher in males than in females, and the increased values ranged between 1.17 and 1.83 and showed statistically significant differences in 35-41 weeks of GA (t=2.73-8.85, P<0.01-P<0.001). Conclusions The QI values of singleton neonates with GA in Shenzhen are increased with the increasing GA, indicating that the body density and enrichment degree are also increased with the increasing GA. There exists a gender difference in the QI values, showing high values in males than in females.
