Abstract

PURPOSE

Mortality rates in the U.S. Army from 2005 to 2011 were examined over time and compared to the U.S. general population.

METHOD

Cases were U.S. Army Soldiers (active duty or activated National Guard/Reserve) with dates of death between 2005 and 2011 and between 18 and 64 years of age in the Department of Defense Medical Mortality Registry. Age- and sex-adjusted annual mortality rates (AR) were calculated for each category of death and examined via linear regression. Proportions of underlying causes of death were also examined.

RESULTS

The trend in AR in the U.S. Army significantly decreased for combat deaths, the average annual percent change (AAPC) = 15.2% decrease in the log of the rate (LAR); p = 0.04 and accident deaths, AAPC = 5.4% decrease in the LAR; p = 0.002 and significantly increased for suicides, AAPC = 10.6% increase in the LAR; p = 0.001. The trend in AR for suicides for the Army was significantly different compared to the U.S. general population, AAPC = 11.0% increase in the LAR; p < 0.001.

CONCLUSIONS

Trends in rates of combat deaths and accident deaths declined although rates of suicides increased. The Army suicide rate increased in comparison to the United States. 70% of accident deaths were transportation related. Almost 70% of suicides and homicides were firearm related.

摘要

目的

对2005年至2011年美国陆军的死亡率进行长期研究，并与美国普通人群进行比较。

方法

研究对象为美国陆军士兵（现役或已动员的国民警卫队/后备役），他们在2005年至2011年期间死亡，年龄在18岁至64岁之间，数据来自国防部医疗死亡率登记处。计算各类死亡的年龄和性别调整后的年死亡率（AR），并通过线性回归进行分析。同时也对潜在死因的比例进行了研究。

结果

美国陆军中，战斗死亡的AR趋势显著下降，年平均百分比变化（AAPC）=率的对数（LAR）下降15.2%；p = 0.04，事故死亡的AAPC = LAR下降5.4%；p = 0.002，自杀死亡的AR趋势显著上升，AAPC = LAR上升10.6%；p = 0.001。陆军自杀死亡的AR趋势与美国普通人群相比有显著差异，AAPC = LAR上升11.0%；p < 0.001。
