  2. Model adjusted for sex (man, woman), age (years), educational level (no education, primary, secondary or university), size of municipality of residence (rural, urban), tobacco consumption (never smoker, former smoker, current smoker), alcohol consumption (non drinker, former drinker, moderate drinker, excessive drinker), coronary disease, stroke, cancer at any site, chronic obstructive pulmonary disease, diabetes mellitus, arterial hypertension, body mass index (quartile 1, quartile 2, quartile 3, quartile 4), score on appropriate SF-36 scale in 2003 (0 to 100 points), number of hours lying or sleeping, and total number of hours spent in all types of physical activity. Sitting hours were not included in the model.
  3. Overall statistical significance (F-test) for each model was p < 0.01.
