*Multivariate model 1 mutually adjusted for all baseline independent variables.
†Multivariate model 2 additionally adjusted for: self-rated health age 42 (excellent; very good; good; fair; poor); participation in vigorous sports age 42; assessment of own weight at age 42 (about right; underweight; overweight; very overweight).
