Abstract

喘息発作の出現と亜熱帯地域に位置する沖縄県地方の気象因子との関連を追求した.気管支喘息患者27例を対象とし過去2年間を, 喘息日記を用いて調査した.喘息発作の程度は, 喘息日記の記載から発作点数合計として算出した.一方, 喘息発作患者の救急車搬送頻度は, 那覇市消防局による過去3年間の調査結果を基にした.沖縄県那覇市の各気象因子が調査期間の平均値より高いか否かと, 喘息発作の発生との因果関係を, 2×2分割表にて分析した.その結果, 喘息日記の調査からは, 平均気温ならびに最低気温がそれぞれ調査期間の平均値を上回る日に喘息発作点数合計の上昇が認められた(p<0.05).一方, 救急車搬送頻度の調査からは, 平均気温および最高気温, 最低気温が調査期間の平均値を下回る日(p=0.0001, p=0.0001, p<0.0001), 平均蒸気圧が平均値を下回る日(p=0.0002), 平均海面気圧が平均値を上回る日(p=0.0016)に喘息発作が起こりやすいと推察された.さらに, 重回帰分析により, 低温の救急車搬送頻度に及ぼす影響の大きいことが示唆された.また, 台風接近にともなう気象因子の急変, 特に, 気温や気圧の急激な低下は喘息発作の誘因になる可能性が示唆された.

The correlation between the outbreaks of asthme attack and meterologic parameters was analyzed in okinawa island which belongs to the subtropics. The epidemiologic outbreaks of asthme were investigated for 2 years from the asthme diaries described by 27 patients. The severity of asthme attack was expressed as the asthme acore on the basis of asthme diaries. The number of patients carried to hospitals by ambulance on asthme attacks was investigated for 3 years. Two-by-two contingency tables were computed for the meteorologic parameters and analyzed with the method of chi-square test. From the view point of asthma scores, the total scores of 27 patients were increased when a mean and a minimum temperature were respectively higher than each mean value in the period of investigation (p<0.05, respectively). From the view point of the number of patients carried to hospitals by ambulance on asthma attacks, it was suggested that asthma attacks tended to occur when a mean, a maximum and a minimum temperature, and a vapor pressure were lower than each mean value (p=0.0001, p=0.0001, p=0.0001, p=0.0002), and a barometric pressure was higher than a mean value in the period of investigation (p=0.0016).From the further analysis of these data by multiple regrassion analysis, it was suggested that the number of patients carried to hospitals by ambulance on asthme attacks was influenced by low temperature. In addition, it was suggested that the changes of meteorologic parameters on the passing over of typhoon, especially, the decrease of temperature and barometric pressure, were related to induce asthma attacks.
