スギ花粉症患者の生活環境調査

Investigation on the Environment and the Mode of Life in Patients of Japanese Cedar Pollinosis

　I．はじめに

　スギは背から日本に広く分布し，当然花粉の飛散も多かったと考えられる。それなのに，スギ花粉症患者が最近になって著しく増加している^1〜3）のはなぜであろうか。

　今回，花粉の側はさておいて，個体の側に原因があるか否かをさぐる目的で，スギ花粉症に代表される春だけのアレルギー性鼻炎患者にアンケート調査を行った。そして，日常生活の面などで鼻アレルギーのない人に比べて，スギ花粉症の人はどんな特徴を示すのかについて検討した結果を報告する。

　This study was designed to detect any causes explaining the recent increase of Japanese cedar pollinosis. Available answers to questionnaire wereobtained from 451 patients of this pollinosis and 148 non-allergic persons.

　Male smokers are 25.1% in the former and 62.7% in the latter (P<0.001). But in other items such as residential environment, structure of house, material of the floor in bedroom, home air-conditioning, daily walking time, degree of inhalation of exhaust gas from cars, degree of passive smoking, favorite diet, foods and drinks, no apparent difference was observed between these two groups.

　At present, it is difficult to find the causes of increasing incidence of Japanese cedar pollinosis in the patients' personal life style.
