目的 调查乌鲁木齐市维吾尔族（简称维族）与汉族新生儿出生体格发育状况。方法 连续测量2014年12月至2017年5月新疆医科大学第一附属医院及妇幼保健院出生的28~42周的单胎活产儿出生体重、身长、头围、胸围，采用一元三次方的曲线拟合方法绘制出生体重、身长、胸围及头围的相关平滑曲线。结果 共纳入胎龄28~42周单胎新生儿5 027名，其中男婴2 625名，女婴2 402名。获得了维族和汉族胎龄28~42周男女新生儿出生体重、身长、胸围、头围及克托莱指数和维尔维克指数的均值，并制定了其百分位平滑曲线。维汉两民族新生儿间部分生长发育指标测量值存在差异。维族与汉族新生儿克托莱及维尔维克指数均随着胎龄增加呈相应增加的趋势，其中维族新生儿维尔维克指数大于汉族。结论 乌鲁木齐维汉两民族新生儿间部分生长发育指标水平及维尔维克指数存在差异。该研究获得的维族和汉族胎龄28~42周男女新生儿出生体重、身长、胸围、头围及克托莱指数和维尔维克指数的均值及其百分位平滑曲线可为乌鲁木齐市新生儿生长发育的评估提供参考。

Objective To investigate the physical development of Uygur and Han neonates in Urumqi, China.Methods Live singleton neonates with a gestational age of 28-42 weeks who were born in the First Affiliated Hospital of Xinjiang Medical University and Maternal and Child Health Care Hospital from December 2014 to May 2017 were enrolled, and their body weight, body length, head circumference, and chest circumference at birth were measured. The cubic curve fitting method was used to plot the smooth curves of body weight, body length, head circumference, and chest circumference.Results A total of 5 027 singleton neonates with a gestational age of 28-42 weeks were enrolled, with 2 625 boys and 2 402 girls. The average values of birth weight, body length, head circumference, and chest circumference, Quetelet index, and Ververck index of Uygur/Han boys and girls with a gestational age of 28-42 weeks were obtained, and related smoothed percentile curves were plotted. There were some differences between Uygur and Han neonates in the average values of some growth and development indices. The Quetelet index and the Ververck index of Uygur and Han neonates increased with the increase in gestational age, and the Uygur neonates had a higher Ververck index than the Han neonates.Conclusions There are differences in the levels of some growth and development indices and Ververck index between the Uygur and Han neonates in Urumqi. The average values of body weight, body length, chest circumference, and head circumference at birth, Quetelet index, and Ververck index of Uygur and Han neonates with a gestational age of 28-42 weeks and their smoothed percentile curves can provide a reference for the assessment of neonatal growth and development in Urumqi.
