A 3 year-study of emergency room visits (total 50,300) to the paediatric clinic of the main teaching hospital in Kuwait revealed that the rates of bronchial asthmatic attacks increased significantly from 8.8% of all visits during the 1st year to 14.9% during the 3rd year. The seasonal distribution of asthmatic attacks showed maximum rates during the winter and minimum values in the summer, giving a very close inverse correlation to temperature and direct correlation to relative humidity. A similar, excellent correlation was seen between asthmatic attacks and upper respiratory infections. Occurrence of atmospheric pollen, which characteristically shows a bi-annual pattern i Kuwait, was not found to correlate with asthma attack rates. Neither was there any demonstrable effect of dust storms on the frequency of asthmatic attacks in the children. Independent of season, the boy to girl ratio among the asthma cases was remarkably constant, around 2:1.
一项针对科威特主要教学医院儿科诊所急诊就诊情况（总计50300例）的为期3年的研究显示，支气管哮喘发作率从第一年占所有就诊病例的8.8%显著增至第三年的14.9%。哮喘发作的季节分布显示，冬季发作率最高，夏季最低，与温度呈非常密切的负相关，与相对湿度呈正相关。哮喘发作与上呼吸道感染之间也存在类似的高度相关性。科威特大气花粉的出现具有典型的两年周期模式，但未发现其与哮喘发作率相关。沙尘暴对儿童哮喘发作频率也没有明显影响。与季节无关，哮喘病例中的男女比例非常稳定，约为2:1。
