Age-, sex-, race-, and employment-adjusted standardized mortality ratios (SMRs) were calculated for sailors committing suicide between 1990 and 1996 and compared with adjusted SMRs for civilians. Cluster analyses were conducted on annual rates from 1983 through 1995 to examine differences between comparison groups across time and location. Results showed fewer than expected suicides for Caucasian and African American males and a somewhat higher than expected suicide rate among other ethnic group males and among Caucasian women. The suicide rate showed an increase during the study period, with some evidence toward a clustering effect in time and space.
计算了1990年至1996年间自杀的水手经年龄、性别、种族和就业情况调整后的标准化死亡率（SMR），并与平民的调整后SMR进行比较。对1983年至1995年的年发生率进行聚类分析，以研究不同时间和地点的比较组之间的差异。结果显示，白人和非裔美国男性的自杀人数低于预期，而其他种族男性和白人女性的自杀率略高于预期。在研究期间，自杀率呈上升趋势，有一些证据表明存在时间和空间上的聚集效应。
