Association between job stress and quality of life in nutritionists working in public hospitals in Rio de Janeiro, Brazil.

Occupational stress has been the object of research in different populations. The aim of this study is to analyze the association between psychosocial job stress and quality of life of nutritionists working in public hospitals in Rio de Janeiro, Brazil. Cross-sectional study in public hospitals with nutritionists working as civil servants and CLT. Psychosocial job stress was assessed through the Demand-Control-Support Questionnaire. Quality of life was assessed through the WHOQOL-Bref. The outcome was modeled by means of multiple linear regression and adjusted by covariates. Job demands were inversely associated with quality of life in the physical and environment domains. Job control was directly associated with quality of life in the psychological domain. High strain, in comparison to low strain, was inversely associated with quality of life in the physical and psychological domains. Social support was directly associated with all fields of quality of life domains. Psychosocial job stress, as expressed by psychological job demands and job control, affects self-assessed quality of life, especially in the physical domain.

Resumo O estresse ocupacional tem sido objeto de pesquisas em diferentes populações. O objetivo deste estudo é analisar a associação entre estresse psicossocial no trabalho e qualidade de vida de nutricionistas que trabalham em hospitais públicos do Rio de Janeiro, Brasil. Estudo seccional em hospitais da rede pública do município do Rio de Janeiro, Brasil. Participaram do estudo os nutricionistas com regime de trabalho estatutário ou celetista. O estresse psicossocial no trabalho foi avaliado por meio do questionário de demanda-controle-apoio social (DCSQ). A qualidade de vida foi avaliada por meio do WHOQOL-Bref. O desfecho foi modelado por meio de regressão linear múltipla e ajustado por covariáveis. A demanda de trabalho associou-se inversamente à qualidade de vida nos domínios físico e meio ambiente. O controle do trabalho esteve diretamente associado à qualidade de vida no domínio psicológico. O alto desgaste, em comparação ao baixo desgaste, esteve inversamente associado à qualidade de vida nos domínios físico e psicológico. O apoio social esteve diretamente associado a todos os domínios de qualidade de vida. O estresse psicossocial no trabalho, expresso pelas demandas psicológicas e pelo controle do trabalho, afeta a autoavaliação da qualidade de vida, principalmente no domínio físico.
