Association of Metabolic Syndrome (MetS) With Physical Performance Scores: The Osteoporotic Fractures in Men (MrOS) Study Baseline Examination.

	MetS		No MetS		Difference between groups	95% CI	P-value
	Mean	95% CI	Mean	95% CI
Model 1	10.81	10.61, 11.00	11.92	11.80, 12.03	1.11	0.88, 1.34	<.001
Model 2	11.05	10.86, 11.24	11.83	11.72, 11.94	0.78	0.56, 1.00	<.001

Note. Values shown are calculated from linear regression models comparing men with and without MetS (referent) as defined by World Health Organization criteria (insulin resistance (evidenced by impaired fasting glucose, diabetes, or hyperinsulinemia) and at least 2 of the following: systolic blood pressure of 140 mmHg or higher or use of anti-hypertensive medication; body mass index of 30 or higher; high density lipoprotein cholesterol < 35 mg/dl; triglycerides of 150 mg/dl or higher). Physical performance was assessed by grip strength, narrow walk speed, walking speed, and time to complete five repeated chair stands; individual scores were converted to quintiles (worst [1] to best [5]; unable to complete=0) and summed for an overall score, which was used in analyses. Model 1 included covariates for age, race, education, and clinic site; Model 2 included additional covariates for smoking, alcohol consumption, physical activity, history of falls/fracture, health status and number of chronic medical conditions. N for Model 1 = 5,457; N for Model 2 = 5,445 due to missing data on some covariates. CI = Confidence interval.
