Measurements of forced vital capacity, forced expiratory volume in 1 sec; and peak expiratory flow were carried out in 623 normal Northern Sudanese, Soutehrn Sudanese, and Tanzanian men 17 of 70 years of age. The widely used prediction formular of these parameters for American, British, and Swedish subjects gave significantly higher values than the observed values in this study. From the results in Northern Sudanese subjects, prediction formulas and nomograms were constructed. They were found to provide accurate predictions for subjects from Southern Sudan and Tanzania. It is therefore confirmed that racial variations in the values of these parameters occur. The present prediction formulas and nomograms are recommended for subjects who are of African ethnic origin.
对623名年龄在17至70岁之间的苏丹北部、苏丹南部和坦桑尼亚正常男性进行了用力肺活量、1秒用力呼气量和呼气峰值流量的测量。针对美国、英国和瑞典受试者广泛使用的这些参数预测公式得出的值明显高于本研究中的观察值。根据苏丹北部受试者的结果，构建了预测公式和列线图。发现它们能为苏丹南部和坦桑尼亚的受试者提供准确的预测。因此证实了这些参数值存在种族差异。建议将目前的预测公式和列线图用于非洲裔受试者。
