This ecologic study assessed whether there was a change in health status in Alaska in the winter of 1992-93 after the introduction of MTBE in gasoline. Methyl tertiary butyl ether(MTBE) is used as a fuel oxygenate in the United States and in Europe. In the winter of 1992-93 MTBE was added to gasoline in the cities of Fairbanks and Anchorage, Alaska. The program was discontinued in Fairbanks in December, 1992, but continued in Anchorage until February 28, 1993.
Outpatient visits for state employees and dependents (n = approximately 28,000) living in Alaska were compared over three winters by analyzing health insurance claims.
Odds ratios were calculated. The odds ratios indicated that the winter of 92-93 was not statistically different from previous winters in numbers of claims for upper respiratory illness, bronchitis, headache, or asthma in either Anchorage or Fairbanks.
There was no increase in claims for respiratory illness in either city after introduction of MTBE.
本生态学研究评估了1992 - 1993年冬季在阿拉斯加汽油中引入甲基叔丁基醚（MTBE）后健康状况是否发生变化。甲基叔丁基醚在美国和欧洲用作燃料含氧化合物。1992 - 1993年冬季，阿拉斯加的费尔班克斯市和安克雷奇市的汽油中添加了MTBE。该计划于1992年12月在费尔班克斯停止，但在安克雷奇持续到1993年2月28日。
通过分析医疗保险理赔数据，比较了三个冬季居住在阿拉斯加的州雇员及其家属（约28,000人）的门诊就诊情况。
计算了比值比。比值比表明，在安克雷奇或费尔班克斯，1992 - 1993年冬季上呼吸道疾病、支气管炎、头痛或哮喘的理赔数量与前几个冬季在统计学上没有差异。
引入MTBE后，两个城市的呼吸道疾病理赔均未增加。
