以回顾性调查的方法对２５３４例小儿哮喘病的特点与患病规律进行了研究。结果：１．内源型占４３。５７％，混合型占３１．９６％，外源型占２４．４７％。年龄愈小，内源型所占比例愈高，２．男性患病率（０．９１％）显著高于女性（０．６９％）；３岁以内小儿患病率随年龄增长逐年增高，３岁以后则随年龄增长逐渐降低，３．首次发病年龄在３岁以内者占７５．６９％。４．首次发病原因和复发诱因均以呼吸道感染占首位。５．好发于冬春季，内源性尤著，外源型夏秋季较多；每天以深夜和清晨为好发时间。６．有明显的遗传倾向。７．防治中滥用激素和抗生素现象较严重，缓解期的防治多被忽视。８．随年龄增长，病情减轻、缓解和痊愈率逐渐升高，呈现青春期前后明显的自然缓解倾向。
