The identification of the relevant PSR associated to SP, according to the major axes of inequality in the labor market, to be able to make specific assessments and interventions targeted to the different groups of workers with the aim of improving their health and reducing the inequalities identified. Objective: To assess the association between psychosocial risk factors (PSRs) and sickness presenteeism (SP) and examine possible differences according to the major axes of inequality in the labor market. Methods: Cross-sectional study based on a representative sample of the Spanish salaried population. Results: Although nearly all PSR show crude associations with SP, when adjusted for every other PSR, only the workers exposed to lack of role clarity (adjusted prevalence ratio [aPR], 1.30; 95% confidence interval [CI], 1.01 to 1.68), having role conflicts (aPR, 1.45; 95% CI, 1.19 to 1.77) and lack of sense of community at work (aPR, 1.30; 95% CI, 1.06 to 1.59) show a significant association. Conclusions: After adjusting for all PSR, those significantly associated to SP belong to the interpersonal relationships domain. Some of the PSR effects change according to the segmentation axes analyzed. [ABSTRACT FROM AUTHOR]
