title: Association of Suicidal Ideation with Job Demands and Job Resources: a Large Cross-Sectional Study of Japanese Workers.
abstract: 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.
