  1. Adjusted for sex, age, BMI, smoking, cardiovascular disease, LTPA, education level, and self-perceived health
  2. aFew people reported WPA
  3. bIn 1994–95, a different LTPA was used (Hard physical activity 0, <1, 1–2, ≥3 h/week)
  4. cIn 2001, the alternatives were “poor”, “not so good”, “good”, and “very good”
