This study aimed to identify the association of suicidal ideation with job demands and job resources among Japanese workers.
Valid data from questionnaires that were pre-collected from 42,499 workers (34,882 males and 7617 females) were used for multilevel logistic regression analyses. Job demands and job resources were selected as potential predictors of suicidal ideation. Lifestyle variables, support from family and friends, and suffering from depressive or eating disorders were used as covariates.
In the employee-level, most job demands and job resources had significant associations with the risk of suicidal ideation in both sexes. High coworker support had a significant negative association with the risk of suicidal ideation in the organization-level, irrespective of their gender. High physical demands and poor physical environment in the organization-level had significant positive associations with increased risk of suicidal ideation only among females.
The risk of suicidal ideation among Japanese workers is associated with job demands and job resources in the employee-level, and coworker support in the organization-level may be important as well.
本研究旨在确定日本工人中自杀意念与工作要求和工作资源之间的关联。
对预先从42499名工人（34882名男性和7617名女性）收集的问卷中的有效数据进行多水平逻辑回归分析。工作要求和工作资源被选为自杀意念的潜在预测因素。生活方式变量、来自家人和朋友的支持以及患有抑郁症或饮食失调症被用作协变量。
在员工层面，大多数工作要求和工作资源与两性的自杀意念风险都有显著关联。在组织层面，无论性别如何，同事的高度支持与自杀意念风险存在显著负相关。在组织层面，高强度的体力要求和恶劣的工作环境仅在女性中与自杀意念风险增加存在显著正相关。
日本工人的自杀意念风险与员工层面的工作要求和工作资源有关，组织层面同事的支持可能也很重要。
