Abbreviations: Age, age at the baseline; CRP, c-reactive protein; IL, interleukin; Time, duration of the follow-up (range 0−6 years). Model 1: unadjusted. Model 2: adjusted for sex, body height, education, physical activity, diseases (hypertension, angina pectoris, chronic heart failure, diabetes and hip osteoarthritis), IL-6 and CRP.
