Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory ratio (FEV1/FVC x 100) and forced mid-expiratory flow between 25% and 75% of FVC (FMF) were measured in 3000 lifelong non-smoking Xhosa black Southern African adult population aged 20-60 yr from Umtata in the Transkei in Southern Africa. FVC, FEV1 and FMF were highly correlated with each other and all were highly correlated with age and standing height. The normal ranges for spirometric measurements were narrower than in many previous studies. Mean FVC in the present study was 13% higher than predicted values from other African adults. The present study is the most recent and the largest study of black Africans using the American Thoracic Society 1987 selection criteria of pulmonary function curves and can be used as a reference value for mainly Xhosa black Southern African adult population.
在来自南非特兰斯凯乌姆塔塔的3000名年龄在20至60岁之间的科萨族南部非洲成年终身不吸烟者中，测量了用力肺活量（FVC）、一秒用力呼气容积（FEV1）、用力呼气比率（FEV1/FVC×100）以及FVC的25%至75%之间的用力呼气中期流速（FMF）。FVC、FEV1和FMF彼此高度相关，并且均与年龄和身高高度相关。肺活量测定值的正常范围比许多先前的研究更窄。本研究中的平均FVC比其他非洲成年人的预测值高13%。本研究是使用美国胸科学会1987年肺功能曲线选择标准对非洲黑人进行的最新且规模最大的研究，可作为主要针对科萨族南部非洲成年人群体的参考值。
