目的 了解０ ～３６ 月龄婴幼儿形态发育的规律和速度，探讨ＷＨＯ 的０～３６ 月龄儿童身高体重参考值及评价标准在我国的适用性。方法 采用追踪性调查的方法连续３年观察合肥市３２１ 名３ 月龄婴儿的身长、体重和胸围的生长发育水平和速度， 并与ＷＨＯ参考值相比较。结果 ２ 岁前女童的形态发育水平明显低于男童，至３ 岁时两者相当；３ ～３６ 月龄，男女童的身长、体重和胸围月增长值均逐渐减小，且无性别差异；与ＷＨＯ 参考值比较，男女童的形态发育水平均随年龄的增长而降低， 特别是男童。结论 ＷＨＯ 的０～３６ 月龄儿童身长体重参考值对我国儿童，特别是１８ 月龄前的儿童并不适用。
Objective To understand the regularity and speed of morphological development of infants from 0 to 36 months old and to discuss the reference value of height and weight of children aged 0-36 months in WHO and its applicability in our country. Methods The follow-up survey was used to observe the growth and development of body length, body weight and chest circumference of 321 three-month-old infants in Hefei for three consecutive years and compared with the WHO reference value. Results The level of morphological development of girls before 2 years old was obviously lower than that of boys. By the age of 3, both of them were equivalent. The monthly growth of body weight and chest circumference of boys and girls were gradually reduced from 3 to 36 months old, and there was no gender difference. Compared with the WHO reference value, the level of morphological development of boys and girls decreased with age, especially for boys. Conclusion The WHO body weight reference values for children aged 0-36 months are not applicable to children in our country, especially children before the age of 18 months.
