↵* Clustering defined as systolic blood pressure ≥130 mmHg, diastolic blood pressure ≥85 mmHg, non-fasting blood glucose ≥6 and body mass index ≥25 kg/m2.
↵† Adjusted for age, sex, smoking status (never, former, current, unknown), marital status (married, unmarried, widow(er), divorced/separated, unknown), education (<9, 10–12, ≥13 y).
↵‡ Summary score of recreational physical activity combining information on frequency, duration and intensity.
