在1912名因疑似过敏而接受皮肤试验的患者中，发现801名患者因屋尘螨或草花粉症而患有哮喘。对他们的性别、转诊年龄和出现症状的年龄进行了分析。在10岁以下的儿童中，屋尘螨哮喘的男女比例为3：1;草花粉症的男女比例为2 - 1：1，与预期一致。随着转诊年龄的增加，性别比例逐渐逆转，在第三个十年女性超过男性。在第四和第五个十年，男女比例平均增加到1 - 8：1。在388名男性和323名女性中获得了可靠的症状发作年龄。其中，280名男性和162名女性在10岁之前首次出现症状，96名男性和148名女性在10至29岁之间首次出现症状。其余12名男性和13名女性在29岁后首次出现症状。
SUMMARY Eight-hundred and one patients amongst 1912 referred for skin testing because of suspected allergies were found suffering from asthma due to the house-dust mite or from grass pollenosis. They were analysed in terms of sex, age of referral and age of onset of symptoms. Amongst children referred below the age of 10 with house-dust mite asthma the ratio of males to females was 3:1; with grass pollenosis 2–1:1, as expected. The sex ratio gradually became reversed with increasing age of referral, females overtaking males in the third decade. Female–male ratios increased to a mean of 1–8:1 in the fourth and fifth decades. Reliable ages of onset of symptoms were obtained in 388 males and 323 females. Of these, 280 males and 162 females experienced their first symptoms before the age of 10 whereas 96 males and 148 females first developed symptoms between 10 and 29 years of age. The remaining 12 males and 13 females showed their first symptoms after the age of 29.
