The association between suicide and combat injuries sustained during the wars in Iraq and Afghanistan was examined. A retrospective population‐based cohort design was conducted using official military records to identify combat injuries (October 7, 2001, to December 31, 2007). Those who were injured during combat had higher crude suicide rates than those who deployed and were not injured (incidence rate ratio [IRR] = 1.50; confidence interval [CI] = 1.06, 2.12), or never deployed (IRR = 1.46; CI = 1.04, 2.06). After adjusting for demographics, these findings were no longer statistically significant. Although our data did not support an elevated suicide risk among wounded service members, additional research is needed to examine the impact of injury severity. 相似文献

Are there gender‐specific risk factors for suicidal activity among patients with schizophrenia and depression? A total of 74 schizophrenia patients (51 men, 23 women) and 77 unipolar nonpsychotic depressed patients (26 men, 51 women) from the Chicago Follow‐up Study were studied prospectively at 2 years posthospitalization and again at 7.5 years. Poor early posthospital global functioning is significantly associated with later suicidal activity only for men in both our schizophrenia and depressive samples. Early display of psychotic symptoms is associated with later suicidal activity among male schizophrenia patients. Early cognitive impairment is not significantly associated with later suicidal activity for any of the four groups of patients. The study results must be seen as exploratory and will hopefully spur future research on this important topic. 相似文献
