Abstract
Purpose
To assess the association between physical job demands (PJD) and physical/cognitive functional limitations, and the role of adverse health behaviours, obesity, and socio-demographic factors as confounders of those associations.
Methods
The sample included 3,368 active subjects aged 18–64 years, randomly selected from North-eastern France. Subjects completed a post-mailed questionnaire. PJD score was defined as the product of years of employment with the cumulative number of a wide range of high job demands. Data were analysed through the logistic regression models.
Results
The physical and cognitive functional limitations affected 16.9 and 28.6% of subjects, respectively. A strong relationship was found between PJD and physical functional limitation: significant odds ratios (OR) adjusted for all the factors studied 1.41 for PJD1-29, 1.72 for PJD30-99, and 2.57 for PJD ≥100 versus PJD0; and between PJD and cognitive functional limitation: OR 1.28 for PJD1-29, 1.60 for PJD30-99, and 2.00 for PJD ≥100 versus PJD0. Adverse health behaviours, obesity and job category were modest confounders of those associations.
Conclusions
This study identified a wide range of job demands and individual characteristics related to physical/cognitive functional limitations. Prevention should aim at improving working conditions and adverse health behaviours.
