Predictors for suicidal ideation after occupational injury

Abstract

Risk of suicide has been associated with trauma and negative life events in several studies. Our aim was to investigate the prevalence and risk factors of suicidal ideation, and the population attributable risk among workers after occupational injuries. We investigated workers who had been hospitalized for ? 3. days after occupational injuries between February 1 and August 31, 2009. A self-reported questionnaire including demographic data, injury condition, and the question of suicidal ideation was sent to 4498 workers at 3. months after their occupational injury. A total of 2001 workers (45.5%) completed the questionnaires and were included in final analysis. The prevalence of reporting suicidal ideation was 8.3%. After mutual adjustment, significant risk factors for suicidal ideation higher than "serious" in a self-rated severity scale (adjusted odds ratio, aOR = 2.31; adjusted population attributable risk, aPAR = 34.7%), total hospital stay for 8. days or longer (OR = 1.98; aPAR = 20.5%), intracranial injury (OR = 2.30; aPAR = 10.2%), and marriage status of being divorced/separated/widowed (OR = 2.70; aPAR = 10.0%). Three months after occupational injury, a significant proportion of workers suffered from suicidal ideation. Significant predictors of suicidal ideation after occupational injury included broken marriage, intracranial injury, injury severity, and total hospital stay. Identification of high risk subjects for early intervention is warranted. ? 2012 Elsevier Ltd.
