富山県におけるスギ花粉症の疫学調査研究—第1報 アンケートの基礎データを中心に

Epidemiological Study on Ceder Pollinosis in Toyama Prefecture

　はじめに

　花粉症は近年増加し，国民の10人に一人が罹患しているといわれている^1）。しかし，スギ花粉症についての全国的疫学調査は厚生省の研究報告^2）以外みられず，一定の地域でのきめ細かい疫学調査も未だにきわめて少ない。今回，私達は，スギ花粉症例の実態の解明のために，富山県を中心に新潟，石川，岐阜の一部の地域の病院，医院に依頼して地域的な疫学調査を行ったので概要を報告する。

An epidemiological study was performed in a total of 2883 patients with ceder pollinosis in Toyama prefecture during the period from Feb-ruary 1st to April 30th in 1991. The most of the patients older than 40 years were free from symptoms before their age of the 20 years, indicating that there was no severe socio-medical problems about ceder pollinosis. Whereas those whose age ranged from 20 to 39 year had an evidence of nasal allergy from adolescence. The possible exp-lanation for these results may be considered that pollens of ceders which were planted after the World War II increased in number at that period, and that sensitization was aquired before adole-scence or puberty. It was March 19th when maximum number of the patients noticed allergic symptoms initially at that season. It was clear in accordance with the maximum number of ceder pollen detected at the Toyama Med. and Pharm. University which is located in the center of the prefecture.
