Coal workers' pneumoconiosis (CWP) is a preventable occupational lung disease caused by inhaling coal mine dust that can lead to premature* death (1,2). To assess trends in premature mortality attributed to CWP (3), CDC analyzed underlying causes of death data from 1999 to 2016, the most recent years for which complete data are available. Years of potential life lost to life expectancy (YPLL) and years of potential life lost before age 65 years (YPLL) were calculated (4). During 1999-2016, a total of 38,358 YPLL (mean per decedent = 8.8 years) and 2,707 YPLL (mean per decedent = 7.3 years) were attributed to CWP. The CWP-attributable YPLL decreased from 3,300 in 1999 to 1,813 in 2007 (p<0.05). No significant change in YPLL occurred after 2007. During 1996-2016, however, the mean YPLL per decedent significantly increased from 8.1 to 12.6 per decedent (p<0.001). Overall, CWP-attributable YPLL did not change. The mean YPLL per decedent decreased from 6.5 in 1999 to 4.3 in 2002 (p<0.05), sharply increased to 8.9 in 2005, and then gradually decreased to 6.5 in 2016 (p<0.001). Increases in YPLL per decedent during 1999-2016 indicate that over time decedents aged ≥25 years with CWP lost more years of life relative to their life expectancies, suggesting increased CWP severity and rapid disease progression. This finding underscores the need for strengthening proven prevention measures to prevent premature CWP-associated mortality.
煤工尘肺（CWP）是一种可预防的职业性肺部疾病，由吸入煤矿粉尘引起，可导致过早死亡（1,2）。为了评估归因于 CWP 的过早死亡率趋势（3），CDC 分析了 1999 年至 2016 年期间的死因数据，这是可获得完整数据的最近年份。计算了与预期寿命相比失去的潜在生命年数（YPLL）和 65 岁前失去的潜在生命年数（YPLL）（4）。在 1999 年至 2016 年期间，共有 38,358 个 YPLL（每个死者的平均值为 8.8 年）和 2,707 个 YPLL（每个死者的平均值为 7.3 年）归因于 CWP。1999 年至 2007 年，CWP 所致 YPLL 从 3,300 减少到 1,813（p<0.05）。2007 年后，YPLL 没有明显变化。然而，在 1996 年至 2016 年期间，每个死者的平均 YPLL 从 8.1 增加到 12.6（p<0.001）。总体而言，CWP 归因的 YPLL 没有变化。每个死者的平均 YPLL 从 1999 年的 6.5 减少到 2002 年的 4.3（p<0.05），在 2005 年急剧增加到 8.9，然后逐渐减少到 2016 年的 6.5（p<0.001）。1999 年至 2016 年期间每个死者的 YPLL 增加表明，随着时间的推移，患有 CWP 的≥25 岁死者相对于其预期寿命失去了更多的生命年数，这表明 CWP 的严重程度增加和疾病快速进展。这一发现强调了需要加强经过验证的预防措施，以防止过早的 CWP 相关死亡。
