从1975年到1993年，每隔一年对大坂府所有公立小学的儿童进行一次问卷调查（共10次）。学校的数量从848所到1 009所不等，学生的数量从514 656人到871 008人不等（每次调查总共有7 128 443人作出答复）。1.喘息的患病率为3.0 +/- 0.1%，在1975-1983年期间几乎保持不变，此后增加到1993年的4.7%。一年级学生的患病率在早期最高，但自1985年以来，患病率随年级增加，导致一至五年级学生之间的患病率差异不大。2.采用个体化问卷调查喘息持续情况。从1985年起，患病率的增加被认为是由于喘息缓解率的降低以及持续状态和症状新发展的增加。3.为了明确患病率与居住地空气污染之间的相关性，对不同地区的患病率进行了比较。商业和工业区的患病率略高于郊区的居民区，但自1985年以来，各地区的患病率普遍增加。
Questionnaire surveys of children in all public primary schools in Osaka Prefecture have been conducted every other year from 1975 to 1993 (10 times in total). The number of schools ranged from 848 to 1,009 and those of the pupils from 514,656 to 871,008 (7,128,443 in total responded to each survey). 1. The prevalence rate of wheezing was 3.0 +/- 0.1% which was almost constant during the period, 1975-1983 and thereafter increased to reach 4.7% in 1993. The rate for 1st-graders was highest early in the period, but the rate increased with grade since about 1985, resulting in a lack of prevalence difference among the 1st to 5th graders. 2. Their persistent conditions of wheezing were investigated according to the individual questionnaires. The increase in the prevalence rate from 1985 was found to be caused by the lowering in the remission rate of wheezing in addition to the increases in persistent states and new developments of the symptoms. 3. Aiming to clarify the correlation between the prevalence rate and the air pollution in their places of residence, the prevalence rate was compared among various areas. The rates were slightly higher in the business and industry area than the residential ones in the suburbs, but increase in the prevalence rate from 1985 was commonly found in the respective areas.
