Hazard ratio for 11-year mortality, by tertiles of energy expenditure at baseline

Energy expenditure in MET-minute/week	Model 1	Model 2	Model 3
	HR (95% CI)	HR (95% CI)	HR (95% CI)
Men
Tertile 1	1.0	1.0	1.0
Tertile 2	0.54 (0.40–0.74)	0.57 (0.42–0.77)	0.59 (0.43–0.81)
Tertile 3	0.37 (0.27–0.52)	0.41 (0.30–0.57)	0.47 (0.34–0.66)
Women
Tertile 1	1.0	1.0	1.0
Tertile 2	0.93 (0.71–1.23)	0.92 (0.70–1.21)	0.99 (0.75–1.31)
Tertile 3	0.74 (0.54–1.02)	0.74 (0.53–1.02)	0.86 (0.62–1.19)
P-value for the interaction between sex and energy expenditure	<0.02	<0.03	<0.02

Notes: Model 1 (n=1,378): adjusted by age, sex, education years and interaction term between tertiles of energy expenditure and sex. Model 2 (n=1,378): model 1 plus current smoking, alcohol consumption, and body mass index. Model 3 (n=1,378): model 2 plus systolic blood pressure, total cholesterol, fasting glucose, stroke, angina, infarct, Mini-Mental State Examination score, and levels of B-type natriuretic peptide. Tertile 1: 0 to 515.0 MET-minute/week; Tertile 2: 515.1 to 1,529.9 MET-minute/week; Tertile 3: 1,530.0 to 16,765.5 MET-minute/week.
