摘要: 目的 建立南京市学龄前儿童吸气肌的预计值,为评价儿童肺功能及运动能力提供一项参考指标。方法 采取分层整群抽样的方法,在南京市主城区抽取236名学龄前儿童,采用Breathe-link呼吸功能评估系统进行吸气肌评估,获得最大口腔吸气压(MIP)及吸气峰流速。采用Pearson相关分析MIP、吸气峰流速与性别、年龄、身高、体重的相关性。采用多元逐步线性回归法获得MIP、吸气峰流速的预计值公式。结果 MIP、吸气峰流速的测量值在男、女童之间,差异无统计学意义(P>0.05);但在不同年龄组之间,差异具有统计学意义,且随年龄增长呈递增趋势(FMIP=13.660,P<0.001,F吸气峰流速=33.581,P<0.001)。MIP、吸气峰流速与儿童年龄、身高、体重呈正相关(P<0.001)。分别以MIP、吸气峰流速作为因变量,以年龄、身高、体重为自变量,进行多元逐步线性回归分析。结果表明,回归模型具有显著的统计学意义(F=12.913、22.398,P<0.001)。回归模型显示,身高是MIP的最佳预测变量,年龄是吸气峰流速的最佳预测变量。结论 本研究为国内首个学龄前儿童吸气肌预计值的研究,生成的预计值公式可为临床吸气肌评估提供参考。

Abstract: Objective To generate reference values for inspiratory muscle of preschool children in Nanjing, so as to provide a reference index for evaluating children′s lung function and exercise performance. Methods A total of 236 preschool children were selected from the main urban area of Nanjing by stratified cluster sampling.The inspiratory muscles were evaluated by breath link respiratory function evaluation system to obtain the maximum inspiratory pressure (MIP) and inspiratory peak flow rate.Pearson analysis was used to determine the correlation of MIP and inspiratory peak flow rate with gender, age, height and weight.Multiple linear stepwise regression analysis was used to obtain the formula of MIP and inspiratory peak flow rate. Results Differences in MIP and peak inspiratory flow rate were not significant between boys and girls (P>0.05), but were statistically significant among different age groups and showed an increasing trend with age (F=13.660, 33.581, P<0.001).MIP and peak inspiratory flow rate were positively correlated with children′s age, height and weight (P<0.001).The regression model, proved to be statistically significant(F=12.913、22.398,P<0.08), indicated that height was the best predictor of MIP and age was the best predictor of inspiratory peak flow rate. Conclusions This study is the first study on the predicted value of inspiratory muscle in preschool children in China.The predicted value formula can provide a reference for clinical inspiratory muscle evaluation.

Key words: inspiratory muscle, maximum inspiratory pressure, inspiratory peak flow rate, preschool children
