Table 4.

Mean values of brachial FMD (%) by four occupational categories, stratified by gender.

	Occupational categories
	Mgt/Prof	Sales/Office	Services	Blue-collar	P-value
Women	(n=288)	(n=185)	(n=139)	(n=55)
Model 1	5.77 ± 0.21	5.75 ± 0.27	4.90 ± 0.24	4.23 ± 0.36	<0.001
Model 2	5.76 ± 0.20	5.92 ± 0.26	4.91 ± 0.24	4.39 ± 0.32	<0.001
Model 3	5.71 ± 0.22	5.82 ± 0.26	5.17 ± 0.26	4.28 ± 0.35	0.002
Model 4	5.73 ± 0.34	5.83 ± 0.40	5.21 ± 0.40	4.27 ± 0.44	0.002
Men	(n=434)	(n=109)	(n=110)	(n=179)
Model 1	4.31 ± 0.12	4.41 ± 0.24	4.40 ± 0.27	3.88 ± 0.19	0.176
Model 2	4.40 ± 0.12	4.41 ± 0.23	4.37 ± 0.26	3.83 ± 0.18	0.042
Model 3	4.32 ± 0.13	4.43 ± 0.23	4.53 ± 0.28	3.87 ± 0.20	0.092
Model 4	4.32 ± 0.28	4.41 ± 0.33	4.48 ± 0.40	3.83 ± 0.33	0.087

Results are mean ± SE.

P-values were obtained from ANOVA/ANCOVA models.

Model 1: Unadjusted.

Model 2: Adjusted for age.

Model 3: Adjusted for age, race/ethnicity, educational level, waist circumference, HDL cholesterol, and total cholesterol.

Model 4: Adjusted for age, race/ethnicity, educational level, waist circumference, HDL cholesterol, total cholesterol, diastolic blood pressure, systolic blood pressure, physical activity, smoking status, and pack-years of smoking.

Interaction by gender (p=0.031) in the association between FMD % and occupational categories.
