  1. * The cut-off points for LTPA quartiles in MET-hr/week were 14.0; 25.0 and 37.5 in men and 10.0; 21.3 and 26.3 in women.
  2. † p < 0.05; ‡ p < 0.01.
  3. Models 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), sitting hours per week (quartile 1, quartile 2, quartile 3, quartile 4) and score on appropriate SF-36 scale in 2003 (0 to 100 points).
  4. Overall statistical significance (F-test) for each model was p < 0.01.
