目的：建立新疆地区正常学龄期儿童最大呼气峰流速正常参考值。方法：2006年4~5月，对新疆地区7~16岁学龄期儿童3 520名（男1 695名，女1 825名），采用德国产的MicroPeak峰速仪测量最大呼气峰流速值，同时记录性别、年龄、身高、体重。采用SPSS14.0统计软件进行分析。结果：不同性别少年儿童中，最大呼气峰流速值随年龄、身高、体重的增加而增加；最大呼气峰流速值与年龄、身高、体重、性别有很高的相关性。结论：建立了最大呼气峰流速值与性别、身高的直线回归方程。呼气峰流速（y）=-342.98+3.94×身高（x1）+26.30×性别（x2）。当知道个体的身高时，即可知道个体的最大呼气峰流速值的预计值。［中国当代儿科杂志，2007，9（5）：419-421］

OBJECTIVE: To establish reference values of peak expiratory flow (PEF) for children in Xinjiang. METHODS: A total of 3520 healthy children (1705 males and 1815 females) aged from 7 to 16 years were enrolled in this study. PEF was measured using MicroPeak Peak Flow Meter. Children's age, sex, height and weight were recorded. Impact factors for PEF were investigated by multiple stepwise regression analysis. RESULTS: PEF values increased with the increase of age, height and weight and correlated significantly with age, height, weight and sex. The regression equation between sex and height and PEF was obtained, i.e, PEF (y)=-342.98+3.94 x Height (x1) + 26.30 x Sex (x2). CONCLUSIONS: PEF values can be calculated according to children's height and sex.
