Baseline Prevalence of Abnormal Metabolic Syndrome Traits by Baseline BMI or Fasting Insulin Quintile

Predictors: BMI or fasting insulin	Outcome: baseline prevelence of metabolic syndrome trait	Baseline BMI or fasting insulin qunitile
Baseline BMI quintile		1	2	3	4	5	P value
	Hypertension (%)	29	34	40	49	65	<0.0001
	High triglycerides (%)	15	23	30	43	47	<0.0001
	Low HDL-cholesterol (%)	22	33	41	47	55	<0.0001
	High fasting glucose (%)	18	20	24	34	43	<0.0001
	Baseline trait score	0.9 (1.0)	1.1 (1.1)	1.4 (1.1)	1.7 (1.2)	2.1 (1.2)	<0.0001
Baseline fasting insulin quintile		1	2	3	4	5	P value
	Hypertension (%)	31	34	41	49	64	<0.0001
	High triglycerides (%)	14	20	28	38	58	<0.0001
	Low HDL-cholesterol (%)	20	29	36	48	67	<0.0001
	High fasting glucose (%)	14	23	24	32	46	<0.0001
	Baseline trait score	0.8 (0.9)	1.1 (1.0)	1.3 (1.1)	1.7 (1.2)	2.3 (1.2)	<0.0001

Date are % or mean [standard deviation (SD)]. Trait score is calculated as the sum of abnormal metabolic syndrome traits.

BMI, body mass index; HDL, high-density lipoprotein.
