Les facteurs de stress psychosociaux au travail sont des expositions courantes qui affectent la population active, et il existe de bonnes preuves qu’ils ont des conséquences néfastes sur la santé. Certains éléments indiquent qu’elles peuvent avoir un impact sur la mortalité, mais cela n’a pas été systématiquement examiné. L’objectif de cet examen systématique était d’examiner l’association entre les facteurs de stress psychosociaux au travail et la mortalité toutes causes confondues et les décès dus aux maladies coronariennes. Les résultats montrent que les travailleurs ayant un faible contrôle de l’emploi sont exposés à un risque accru de mortalité toutes causes confondues et de maladies coronariennes comparativement aux travailleurs ayant un contrôle élevé de l’emploi. Les interventions politiques et pratiques visant à améliorer le contrôle de l’emploi pourraient contribuer à réduire la mortalité.
OBJECTIVES Psychosocial work stressors are common exposures affecting the working population, and there is good evidence that they have adverse health consequences. There is some evidence that they may impact on mortality, but this has not been systematically examined. We performed a systematic review, including risk of bias, and meta-analyses of observational studies to examine the association between psychosocial work stressors and all-cause mortality and death due to coronary heart disease (CHD). METHODS Electronic databases were searched to identify studies and information on study characteristics and outcomes extracted in accordance with PRISMA guidelines. Risk estimates of outcomes associated with psychosocial work stressors: specifically, all-cause mortality, and death due to CHD were pooled using inverse variance weighted random effects meta-analysis. RESULTS We identified 45 eligible cohort studies, of which 32 were included in the quantitative analyses of psychosocial work stressors and mortality. Low job control was associated with an increased risk of all-cause mortality [hazard ratio (HR) 1.21, 95% confidence interval (CI) 1.07–1.37, minimally-adjusted; HR 1.05, 95% CI 1.01–1.10, multivariable-adjusted; HR 1.03, 95% CI 1.00–1.06 exclusion of low quality studies and multivariable-adjusted] and CHD mortality [HR 1.50, 95% CI 1.42–1.58, minimally-adjusted; HR 1.23, 95% CI 1.17–1.30, multivariable-adjusted; HR 1.19, 95% CI 1.01–1.40, exclusion of low quality studies and multivariable-adjusted]. CONCLUSIONS Workers with low job control are at increased risk of all-cause and CHD mortality compared to workers with high job control. Policy and practice interventions to improve job control could contribute to reductions in all-cause and CHD mortality.
