Associations Between Physical Activity Timing Clusters and Cardiovascular Events, CoLaus-PsyCoLaus Study, Lausanne, Switzerland

	Cluster Number
	1 (n = 386)	2 (n = 364)	3 (n = 670)	4 (n = 639)
Number of events	4	19	30	17
Incidence	0.2 (0.1-0.6)	1.2 (0.7-1.8)	1.0 (0.7-1.4)	0.6 (0.4-1.0)
Unadjusted	1.00 (reference)	5.16 (1.76-15.2)	4.40 (1.55-12.5)	2.56 (0.86-7.62)
Adjusted model 1	1.00 (reference)	3.90 (1.29-11.8)	2.93 (1.00-8.59)	3.36 (1.12-10.1)
Adjusted model 2	1.00 (reference)	3.33 (1.08-10.3)	2.83 (0.96-8.34)	3.16 (1.04-9.57)
Adjusted model 3	1.00 (reference)	3.34 (1.11-10.1)	2.84 (0.99-8.17)	3.16 (1.06-9.43)

BMI = body mass index; CVD = cardiovascular disease.

Incidence rates are expressed as rate per 1,000 person-years (and 95% CIs). For unadjusted and adjusted analysis, results are expressed as HR (95% CI). Analyses conducted using Cox regression for CVD events. Adjusted model 1: adjusted for sex (male, female), age (continuous), educational level (basic, apprenticeship, secondary, high school, and university), alcohol consumption (none, 1-13, 14-27, and 27+ per week), smoking categories (never, former, current), and BMI categories (normal, overweight, and obese). Adjusted model 2: as model 1, plus hypertension (yes, no), diabetes (yes, no), and hypolipidemic drug treatment (yes, no). Significant (P < 0.05) coefficients are indicated in bold. Adjusted model 3: Fine-Gray model, using non-CVD death as a competing risk, and adjusting as for model 2.
