sedentary office workers) and adjusting for covariates, retirement was associated with lower mortality in women (HR = 0.62, CI: 0.53–0.72) and men (HR = 0.80, CI: 0.71–0.90), whereas unemployment was associated with higher mortality in men only (HR = 1.24, CI: 1.07–1.45).
Occupational physical activity definition manual#
Compared to those reporting no heavy manual or walking/standing work (e.g. Resultsĭuring 5,449,989 person-years of follow-up, 28,740 deaths occurred. Models included adjustment for age and a range of lifestyle, socio-economic and health-related covariates. Cox proportional hazards models were used to estimate sex-stratified hazard ratios (HR) and 95% confidence intervals (CI) for mortality from all causes, CVD, and cancer by occupational group, and for working hours/week and non-occupational physical activity stratified by occupational group. OPA was categorised by cross-tabulating degree of manual work and walking/standing work amongst those in paid employment ( n = 267,765), and combined with categories of occupational status for those not in paid employment ( n = 193,136).
The purpose of this study was to investigate associations between OPA and mortality outcomes. Current physical activity guidelines do not distinguish between activity accumulated in different behavioural domains but some studies suggest that occupational physical activity (OPA) may not confer health benefits and could even be detrimental.
