^aThe model included all variables in the table and the number at risk (N = 13763) included all individuals with no missing data in any of the variables in the model.

^bTotal alcohol consumption: None = 0; Moderate = 1–199 g/week for men and 1–99 g/week for women; Heavy ≥ 200 g/week for men and ≥ 100 g/week for women.

^cBlood pressure was considered elevated if systolic pressure was ≥ 140 or diastolic pressure ≥ 90 or antihypertensive medication was used.

^dThe cut-off was based on the definition of metabolic syndrome, according to the International
