Prediction equations for peak expiratory flow rate (PEFR) of Malay, Chinese and Indian children were obtained by analysing 1020 PEFR recordings of children free of respiratory symptoms and illnesses. Boys had significantly higher PEFR than girls. For both sexes the highest levels of PEFR were observed in Malays and the lowest in Indians. The differences between Malay and Chinese boys were not statistically significant but the levels of PEFR for Malay and Chinese boys were significantly higher than those for Indian boys. In girls the differences among the ethnic groups were not statistically significant. Although ethnic differences were observed in boys these differences might not be clinically important. A common prediction equation for each sex should be both practical and accurate. When compared with predicted levels for white American and Australian children the predicted levels of PEFR of Malaysian children were found to be lower; these differences could be clinically important and the use of standards for Western children when assessing Malaysian children might not be appropriate.
通过分析1020名无呼吸道症状和疾病儿童的呼气峰值流速（PEFR）记录，得出了马来族、华裔和印度裔儿童的PEFR预测方程。男孩的PEFR显著高于女孩。在两个性别中，马来族儿童的PEFR水平最高，印度裔儿童的最低。马来族和华裔男孩之间的差异无统计学意义，但马来族和华裔男孩的PEFR水平显著高于印度裔男孩。在女孩中，不同种族之间的差异无统计学意义。尽管在男孩中观察到了种族差异，但这些差异可能在临床上并不重要。为每个性别制定一个通用的预测方程应该既实用又准确。与美国白人和澳大利亚儿童的预测水平相比，发现马来西亚儿童的PEFR预测水平较低；这些差异可能在临床上具有重要意义，在评估马来西亚儿童时使用西方儿童的标准可能不合适。
