Using a large cohort of western Canadian sawmill workers (n = 28,794), the association between psychosocial work conditions and attempted and completed suicide was investigated.
Records of attempted and completed suicide were accessed through a provincial hospital discharge registry to identify cases that were then matched using a nested case control method. Psychosocial work conditions were estimated by expert raters using the demand-control model. Univariate and multivariate conditional logistic regression was used to estimate the association between work conditions and suicide.
In multivariate models, controlling for sociodemographic (marital status, ethnicity) and occupational confounders (job mobility and duration), low psychological demand was associated with increased odds for completed suicide, and low social support was associated with increased odds for attempted suicides.
This study indicates that workers with poor psychosocial working conditions may be at increased risk of both attempted and completed suicide.
利用一大群加拿大西部锯木厂工人（n = 28,794），研究了心理社会工作条件与自杀未遂及自杀死亡之间的关联。
通过省级医院出院登记处获取自杀未遂及自杀死亡记录，以识别病例，然后采用巢式病例对照方法进行匹配。心理社会工作条件由专家评估者使用需求 - 控制模型进行评估。采用单变量和多变量条件逻辑回归来估计工作条件与自杀之间的关联。
在多变量模型中，在控制社会人口学因素（婚姻状况、种族）和职业混杂因素（工作流动性和工作时长）后，低心理需求与自杀死亡几率增加相关，低社会支持与自杀未遂几率增加相关。
本研究表明，心理社会工作条件较差的工人自杀未遂和自杀死亡的风险可能会增加。
