Exposure to Psychosocial Risk Factors at Work and the Incidence of Occupational Injuries: A Cohort Study in Spain.

Abstract

The aim of this study is to analyze the association between the exposure to psychosocial risk factors at work and the incidence of occupational injuries (OIs). A prospective dynamic cohort study (n = 16,693) of 1-year follow-up. Psychosocial risk factors at work were assessed with the Spanish version of Copenhagen Psychosocial Questionnaire. Incidence rates of OI per 1000 workers-year were calculated and associations between psychosocial risk factors and OI were estimated by Poisson regression models. Unfavorable levels of esteem in men [rate ratio (RR) = 1.28], and unfavorable levels of social support and quality of leadership (RR = 1.87), psychological demands (RR = 2.20), and active work and possibilities for development (RR = 1.83) among women, were associated with OI incidence. Poor quality of psychosocial work environment increases the incidence of OI. Psychosocial intervention programs could be helpful in order to reduce OI incidence rates and their associated costs.
