299名健康男童经鼻吸气压力调查

Sniff Nasal Inspiratory Pressure in 299 Healthy Boys

目的调查中国健康男性儿童经鼻吸气压力（SNIP）的范围。方法对299名5-12岁健康男童进行SNIP测量。记录每名参与者的身高、体重、出生日期及测试时间。结果 299名参与者SNIP的平均值为（76.9±22.6）cm H2O。5-6岁、7-8岁、9-10岁、11-12岁SNIP的平均值分别为（59.1±14.2）cm H2O、（76.9±19.5）cm H2O、（85.3±23.5）cm H2O、（83.0±22.6）cm H2O。5-6岁、7-8岁及9-10岁间SNIP有显著性差异（P〈0.05）,9-10岁与11-12岁间SNIP无显著性差异（P=0.55）。SNIP与年龄、身高、体重及体质量指数间存在相关性（P〈0.01）。结论中国健康男童SNIP参考值与国外存在一定差异,有必要建立中国儿童SNIP正常参考值范围。

Objective To investigate the sniff nasal inspiratory pressure（SNIP） of Chinese boys. Methods 299 healthy boys aged 5-12 years were measured with SNIP. Their height, weight, and age were recorded. Results The SNIP averaged（76.9 ± 22.6） cm H2 O, and was（59.1±14.2） cm H2 O,（76.9±19.5） cm H2 O,（85.3±23.5） cm H2 O and（83.0±22.6） cm H2 O in the boys of 5-6 years old, 7-8 years old, 9-10 years old and 11-12 years old, respectively. It was significantly different among boys of 5-6 years old, 7-8 years old and 9-10 years old（P〈0.05）,but no significant difference between 9- 10 years old and 11- 12 years old（P=0.55）. Regression analysis indicated significant relations of SNIP with age, height, weight and Body Mass Index（P〈0.01）. Conclusion The SNIP of Chinese healthy boys are different from abroad. It is necessary to establish the Chinese children SNIP reference range.
