Abstract:
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.
