Abstract

ABSTRACTOBJECTIVE To analyze the interaction between the psychosocial aspects of work and the occurrence of common mental disorders among health workers.METHODS This is a cross-sectional study conducted with a representative sample of workers of the primary health care of five municipalities of the State of Bahia, Brazil, in 2012. The variable of outcome were the common mental disorders evaluated by the SRQ-20, and the variables of exposure were high demand (high psychological demand and low control over the work) and low social support in the workplace. Interaction was checked by the deviation of the additivity of the effects for the factors studied from the calculation of excess risk from interaction, proportion of cases attributed to interaction, and the synergy index.RESULTS The global prevalence of common mental disorders was 21%. The group of combined exposure has shown higher magnitude (high demand and low social support), reaching 28% when compared to the 17% in the situation of no exposure (low demand and high social support).CONCLUSIONS The results strengthen the hypothesis of interaction between the factors investigated, directing to the synergy of the effects.

Summary

Introduction

The scientific literature points to the influence that work has on the lives of individuals[18,19]. Mental disorders related to work reach a significant portion of the Brazilian working population. They are responsible for the third place in the ranking related to the granting of sickness benefits[25]. Common mental disorders (CMD), of high occurrence among health workers, have been observed as a factor associated with presenteeism, absenteeism, and disabilities[22]. Their occurrence among health workers is a problem of great relevance, because this implies impairment of the care provided to the user of the health system[1]
