Ageing workers’ mental health during COVID-19: a multilevel observational study on the association with the work environment, perceived workplace safety and individual factors

OBJECTIVES: The stress and anxiety associated with the predisposition of ageing workers to severe COVID-19 illness, once occupationally infected, jeopardise their mental health. This study aimed to investigate the association between individual level, work environment exposure factors and perceived workplace safety with a decline in mental health of ageing workers from different industry sectors. DESIGN: Observational study, prevalence assessment of survey added to longitudinal cohort data. SETTING: The Survey of Health, Ageing and Retirement in Europe (SHARE) from 27 countries in Europe and Israel participating in the COVID-19 survey (summer 2020) and having prepandemic waves’ SHARE data. PARTICIPANTS: Workers aged 50–70 (n=6449) who attended their workplaces at least partially after the pandemic broke out. PRIMARY OUTCOME MEASURE: Perceived decline in mental health compared with preoutbreak status. RESULTS: Multilevel analyses demonstrated that 24.5% (95% CI 23.5% to 25.5%) of ageing workers in Europe experienced mental health decline associated with national-level self-reported COVID-19 burden. Workplace safety perception was the strongest predictor, as each one-point increase in unsafe perception was associated with 60% of mental health decline (OR=1.6, 95% CI 1.47 to 1.74), explaining 30% of increased reported mental health symptoms of ageing workers. Safety perception mediates the mental health outcomes of the work environment, such as workplace contagion risk and work location. Female gender (OR=1.77, 95% CI 1.55 to 2.02), financial difficulties (OR=1.19, 95% CI 1.1 to 1.28), higher vulnerability index (comorbidities, age >60) (OR=1.11, 95% CI 1.05 to 1.18), pre-existing mental problems (OR=1.78, 95% CI 1.55 to 2.04) and increased national burden of COVID-19 (OR=1.01, 95% CI 1.0 to 1.02) were associated with declines in mental health, whereas exclusively working on-site was protective. CONCLUSION: Vulnerable subgroups for mental health declines among ageing workers were revealed, which warrant their screening and employers’ evaluation of workplace conditions of ageing workers to prevent mental health-related implications. Workplace interventions should aim to reduce work environment influences on infection risk and mental distress.
