SD: standard deviation; SE: standard error.
^aWaist tertiles were 80–89.4, 89.5–97.9, and 98–126 cm for men, 64.5–74.9, 75–86.9, and 87–110.1 cm for women, and 64.5–85.1, 85.2–92.4, and 92.5–126 cm for all police officers.
^bAdjusted for age, smoking, and physical activity.
^cP values are from linear regression models.
^dMedian value was 0.88 drinks per week. P value for interaction with alcohol was 0.30.
