The Impact of Psychosocial and Physical Work Experience on Mental Health: A Nested Case Control Study

Publication: Canadian Journal of Community Mental Health

Abstract

This investigation is a nested case control study based on a large cohort of sawmill workers employed in 14 sawmills in British Columbia (BC) in Western Canada. The purpose of the study was to assess the association between objectively measured physical and psychosocial work conditions and objectively measured mental health outcomes using a longitudinal study design. The investigation ensured that all cases and controls were free of mental health disease for a 5-year period prior to commencement of the study. The study found that Sikh sawmill workers had elevated odds for all the mental health outcomes investigated, and that workers with low duration of employment had elevated odds for adjustment reaction and acute reaction to stress. After controlling for sociodemographic and nonphysical/nonpsychosocial work condition confounders, high psychological demand was associated with elevated odds for neurotic disorder.

Résumé

Cet article rend compte d'une étude longitudinale de cas-témoins emboîtés réalisée sur une large cohorte de travailleurs de 14 scieries de la Colombie-Britannique. L'objectif était d'évaluer le lien entre d'une part des conditions de travail physiques et psychosociales (mesurées objectivement), et d'autre part les effets de celles-ci sur la santé mentale (mesurés objectivement). Aucun des sujets observés n'avait souffert de maladie mentale durant les cinq années précédant la recherche. L'étude a permis de montrer que, chez les travailleurs sikhs, les risques de toutes les maladies mentales étudiées sont plus élevés, et que, chez les travailleurs engagés depuis peu, les risques de troubles de l'adaptation et d'état réactionnel aigu à une situation très éprouvante sont plus importants. Finalement, nous avons observé que, les variables confusionnelles (facteurs sociodémographiques et conditions de travail non physiques et non psychologiques) étant maintenues constantes, la pénibilité du travail (« high psychological demand ») est associée à des risques plus élevés de troubles névrotiques.
