摘　　要：目的 了解并分析6月龄前不同喂养方式下监测地区0~24月龄婴幼儿各随访点的身长水平现状和差异。方法 基于我国5省监测区县儿童随访数据,分别描述6月龄前不同喂养方式下南、北方监测地区0~24月龄男、女童各随访点(出生、1、3、6、8、12、18、24月龄)的身长水平,并采用t检验或方差分析等统计方法对其进行分析。结果 各随访时间点男童的平均身长高于女童,北方监测地区儿童的平均身长高于南方监测地区,差异均有统计学意义(P<0.05)。6月龄前不同喂养方式下北方监测地区男童8、12、18、24月龄身长的组间差异有统计学意义(F值分别为6.56、6.93、5.25、6.99,P<0.05),女童仅24月龄时身长水平存在统计学差异(F=4.39,P<0.05),其余随访月龄不同喂养方式间的身长差异均无统计学意义(P>0.05)。南方监测地区男童、女童各随访点身长水平在不同喂养方式间的差异均无统计学意义(P>0.05)。结论 6月龄前不同喂养方式下,南北方监测地区儿童的6月龄内身长水平无明显差异;6月龄后仅北方监测地区8~24月龄男童和24月龄女童呈现部分差异,关于6月龄前喂养方式对儿童6月龄之后身长的影响尚待进一步研究明确。Objective To understand and analyze the status and differences of body length level of infants aged 0-24 months with different feeding patterns before 6 months of age in different follow-up points in monitoring areas.Methods Based on data of infants from five provinces of China, the body length of boys and girls aged 0-24 months under different feeding patterns before 6 months of age in the southern and northern China were described at each time point of follow-up(0, 1, 3, 6, 8, 12, 18, and 24 months of age), and analyzed by t-test or ANOVA.Results At each follow-up time point, the average body length of boys was higher than that of girls, and the average body length of infants in northern China was higher than that in southern China, the differences were statistically significant(P<0.05).There were statistically significant differences in the length of boys aged 8, 12, 18, and 24 months in the northern China under different feeding patterns before 6 months of age(F values were 6.56, 6.93, 5.25 and 6.99, respectively, P<0.05).There were statistical differences in the length of girls only at 24 months of age(F=4.39, P<0.05), and there were no statistically significant differences in the body length at the other follow-up months(P>0.05).There were no statistically significant at any each time point of follow-up among boys or girls in southern China(P>0.05).Conclusion There is no significant difference in the body length level of infants in the northern and southern China under different feeding patterns before 6 months of age.After 6 months of age, only boys aged 8-24 months and girls aged 24 months showed partial differences in the northern China.The relationship between feeding patterns before 6 months of age and the length of infants after 6 months old need to be further investigated.
