Separate models were tested for each work-related physical activity measure (i.e., walking, moderate, vigorous, total). For rows one and two in each model, the reference category is the lowest PA category (i.e., no PA or low PA). For row three, the highest category is compared to the middle PA category. All models were adjusted for neighbourhood clustering as well as for age, BMI, education status, physical illness, and leisure-time physical activity. PA physical activity
