Respiratory function tests have been performed on 43 Malaysian aboriginals. The forced vital capacity and forced expiratory volume in one second (FEV) were considerably below, and the peak expiratory flow rate (PEFR) slightly below, the predicted values. The FEV and PEFR decreased more rapidly with advancing age than predicted from western standards. These findings may be due to physiological differences or may be the result of chronic purulent bronchitis which is common among the aboriginals.
对43名马来西亚原住民进行了呼吸功能测试。其用力肺活量和一秒用力呼气量（FEV）显著低于预测值，呼气峰值流速（PEFR）略低于预测值。与西方标准预测的情况相比，FEV和PEFR随年龄增长下降得更快。这些发现可能是由于生理差异，也可能是原住民中常见的慢性化脓性支气管炎导致的。
