Table 3. Evaluating the Incremental Effect of MetS on Mortality Risk by Comparing Adults With and Without MetS (N = 12,047), by Weight Status,^a National Health and Nutrition Examination Survey, 1999–2010, and National Death Index, 2011^b .

Model	Hazard Ratio (95% Confidence Interval) [P Value]
	Normal Weight With MetS	Overweight With MetS	Obese With MetS
Unadjusted	4.61 (3.20−6.64) [<.001]	2.49 (1.94−3.20) [<.001]	1.84 (1.30–2.62) [<.001]
Age, sex adjusted	1.71 (1.19−2.46) [.004]	1.21 (0.94−1.56) [.13]	1.18 (0.85−1.63) [.32]
Multivariate adjustedc	1.70 (1.16–2.51) [.008]	1.11 (0.86–1.42) [.43]	1.20 (0.85–1.70) [.29]

Abbreviation: MetS, metabolic syndrome.

^a Based on standard definitions: normal weight (18.5 to <25.0 kg/m²), overweight (25.0 to <30.0 kg/m²), and obese (≥30.0 kg/m²).

^b The reference group for each hazard ratio is the counterpart without MetS in each weight category.

^c Adjusted for age, sex, race/ethnicity, education, poverty-income ratio, smoking status, and physical activity.
