To find out the normal peak expiratory flow rate for adult Saudi males and to compare our standards with British standards.
A cross-sectional study was carried out in five primary health care centers representing Riyadh city in the period between 15(th) November through December 1993. Six hundred and eighty Saudi men who satisfied stringent criteria of normality were included in the study.
The mean and standard deviation of the subjects' age and height were 28.4 ± 13 and 167.6 ± 6.4 respectively. Linear regression analysis was performed through step-wise procedure to determine the form of regression of peak expiratory flow on age and height. Regression curves were obtained and it was found that peak expiratory flow rate did not begin to decline until about the age of 25 years; and as height increased the peak expiratory flow rate increased in a linear relationship.
It was demonstrated that our study group had lower peak expiratory flow rate compared with British people. These findings will serve as a basis for preparing flow rate values for our population.
确定沙特成年男性的正常呼气峰值流速，并将我们的标准与英国标准进行比较。
1993年11月15日至12月期间，在代表利雅得市的五个初级卫生保健中心进行了一项横断面研究。680名符合严格正常标准的沙特男性被纳入研究。
受试者的年龄和身高的平均值及标准差分别为28.4±13和167.6±6.4。通过逐步程序进行线性回归分析，以确定呼气峰值流速与年龄和身高的回归形式。获得了回归曲线，发现呼气峰值流速直到约25岁才开始下降；并且随着身高增加，呼气峰值流速呈线性增加。
结果表明，与英国人相比，我们的研究组呼气峰值流速较低。这些发现将作为为我们的人群制定流速值的基础。
