CI = confidence interval; RR = rate ratio.
a
Adjusted for age (5‐year age groups; 45–49, 50–54, 55–59, 60–64, 65–69, 70–74, 75–79), smoking (never, past, current ≤10, >10 cigarettes/day), alcohol consumption (g/day in quartiles), steroid medication use (yes/no), vitamin supplement use (yes/no), educational level (<10, 10–12, >12 years), physical activity (metabolic equivalent of the task, hr/day in quartiles).
b
Waist cut‐off point for European men according to Joint Interim Statement (JIS)4.
c
Reference group is men without any of the three components of the metabolic syndrome.
