Work strain in midlife and 28-year work ability trajectories
OBJECTIVES: We investigated the 28-year development trajectories of work ability among initially middle-aged male and female municipal employees and the association of perceived mental and physical work strain in midlife by work ability trajectory groups. METHODS: The baseline data of the Finnish lo...

Individuals who maintained their work ability on an excellent-to-moderate level throughout the follow-up more often reported low mental and physical work strain in midlife. CONCLUSIONS: A substantial proportion of individuals seem to maintain their work ability on a moderate level from midlife to old age. Work strain may have far-reaching negative effects on individuals’ work ability from midlife to old age, warranting vigilance in maintaining and promoting work ability throughout the lifespan. https://www.sjweh.fi/show_abstract.php?abstract_id=3177 work abilitywork strainageingdevelopment trajectorymental work strainphysical work strain |
