| 目的探索藏族婴儿出生到l岁时体重和身长生长规律，为体格发育评价提供参考。方法对拉萨农村地区253名藏族婴儿，纵向随访12个月，监测0、1、3、6、12月龄共5个时间点，得到体格发育及婴儿基本情况数据，计算婴儿的重量指数(Pi)值。应用广义线性混合效应模型，控制出生体重、身长后，分析不同性别婴儿身长、体重变化。结果6月龄和12月龄婴儿体重较出生时分别增加1倍和3倍，6月龄身高增加约15 cm，12月龄增加约23 cm。混合效应模型结果显示，藏族婴儿体重、身长均显著增加(体重：13=1.69，P<0.000 1；身长：β=6.527 1，P<0.000 1)；但体重、身长的增加无性别差异(体重：β=o.118 4，P=O.604 3；身长：β=1.4704，P=0.078 8)，出生体重／身长对后期的增量有显著影响(体重：β=一0.681 9，P<0.000 1；身长：β=一0.957 l，P结论藏族儿童婴儿期体格发育的性别差异无统计学意义，但出生体重或身长对后期体重或身长的增长有显著影响。藏族婴儿体格发育低于WHO和“中国九市儿童体格发育调查”标准，但反映身体充盈度的PI值较高，提示藏族婴儿体格发育有其自身特点。 |

| Objective To investigate the growth paRem of rural Tibetan children in the first year afler birth.Methods In rural area of Lhasa，Tibet，252 subjects were recruited and their weight，length were measured longitudinally from birth to 1 2th months of age.Frequency of monitoring reached 5 times in total and Ponderal index(PI)was calculated for each visit.Mixed model was used to analyze the changes of length and weight by gender after controlling for birth weight.Results Birth weight and length showed great influence on children’S growth(weight：β=一0.68 1 9，PConclusion The growth paRern of Tibetan infants might have its own feature.Tibetan infants appeared to have had higher PI，which was contradictory to the general conclusion that poor growth and development status had been seen in Tibetan children. |
