Epidemiologic studies of suicide in the military have not controlled for the higher suicide rates of the unemployed expected in comparative national populations. This study compared the observed number of suicides among U.S. Marine Corps personnel from 1990 to 1996 with the expected number based on rates for the employed general U.S. population. Standardized mortality ratios were calculated to identify demographic groups with higher or lower than expected numbers of suicides. The scan statistic and the Knox technique were used to evaluate potential suicide cluster patterns. Overall, there were fewer suicides in the Marine Corps (n = 213) than expected (n = 225). Hispanic and other ethnic group males and female Marines had greater than expected numbers. Evidence for suicide clustering in time and space was equivocal.
针对军队自杀情况的流行病学研究并未对比较的全国人口中预计较高的失业者自杀率进行控制。本研究将1990年至1996年美国海军陆战队人员中的自杀观察数与基于美国就业总人口率的预期数进行了比较。计算标准化死亡率比以确定自杀人数高于或低于预期的人口统计学群体。扫描统计法和诺克斯技术用于评估潜在的自杀聚集模式。总体而言，海军陆战队的自杀人数（n = 213）低于预期（n = 225）。西班牙裔和其他种族群体的男性和女性海军陆战队员的自杀人数高于预期。在时间和空间上自杀聚集的证据并不明确。
