  1. Statistical analysis: Logistic regression models with odds ratio (OR) and their 95% confidence interval. Results in bold indicate a significant finding. Data for reference category ‘low occupational sitting’ is not shown. For absorption, there were no participant data for the low absorption category. Therefore only two categories were used. Job performance is entered as interval data, where a high score indicates higher job performance. For high job strain and low job strain the reference category is ‘no’. aAdjusted for age, BMI, physical activity, smoking, marital status, dependents and education; bFurther adjusted for job grade and working hours. p < .05.
