Exposure to asbestos fibers can cause asbestosis and other diseases after a latency of 10-40 years from initial exposure to onset of illness. Asbestos still is used in the United States (approximately 2,200 metric tons in 2006) in certain products manufactured domestically. In addition, an undocumented amount of asbestos continues to be imported in products manufactured elsewhere, and a substantial amount of asbestos remains in existing buildings and manufactured products. An estimated 1.3 million construction and general industry workers in the United States potentially are exposed to asbestos each year, mainly from manipulation of asbestos during renovation or demolition activities. Also, although asbestos ore is no longer mined in the United States, some U.S. mine workers might remain at risk for exposure to asbestos contained in other ores. To characterize trends in premature mortality attributed to asbestosis in the United States, CDC analyzed annual underlying cause-of-death data for 1968-2005, the most recent years for which data were available. This report describes the results of that analysis, which indicated that annual years of potential life lost before age 65 years (YPLL) attributed to asbestosis increased 64%, from an average of 146.0 YPLL per year during 1968-1972 to 239.6 per year during 2001-2005 (regression trend for the 5-year moving average, p<0.001), for an overall total of 7,267 YPLL (mean per decedent: 6.2) over the entire period. These results demonstrate that asbestosis-attributable YPLL continue to occur and that efforts to prevent, track, and eliminate asbestosis need to be maintained.
接触石棉纤维后,从初次接触到发病有10至40年的潜伏期,可导致石棉肺和其他疾病。在美国,某些国内生产的产品仍在使用石棉(2006年约2200公吨)。此外,在其他地方生产的产品中仍有无记录数量的石棉被进口,并且大量石棉仍存在于现有建筑物和制成品中。据估计,美国每年约有130万建筑和一般行业工人可能接触石棉,主要是在翻新或拆除活动中处理石棉时接触。此外,尽管美国不再开采石棉矿,但一些美国矿工可能仍面临接触其他矿石中所含石棉的风险。为了描述美国因石棉肺导致的过早死亡趋势,美国疾病控制与预防中心(CDC)分析了1968 - 2005年(可获取数据的最近年份)的年度潜在死因数据。本报告描述了该分析结果,结果表明,65岁前因石棉肺导致的潜在寿命损失年数(YPLL)每年增加64%,从1968 - 1972年期间平均每年146.0 YPLL增加到2001 - 2005年期间的每年239.6 YPLL(5年移动平均值的回归趋势,p<0.001),整个期间总计7267 YPLL(每个死者平均:6.2)。这些结果表明,因石棉肺导致的YPLL仍在继续发生,预防、追踪和消除石棉肺的工作需要持续开展。
