Results of the multivariate logistic regression analysis of association between fiber intake and nonfatal cardiovascular/cerebrovascular events, weighted.
| Variable | Model1a [OR (95%CI)] | Model2b [OR (95%CI)] | Model3c [OR (95%CI)] |
|---|---|---|---|
| Fiber intake (g/day) | 0.98 (0.97, 0.99) | 0.97 (0.96, 0.99) | 0.98 (0.96, 1.00) |
| Fiber intake (Tertile), n (%) | |||
| Tertile1 (n = 2,929) | Ref | Ref | Ref |
| Tertile2 (n = 2,959) | 0.83 (0.66, 1.04) | 0.76 (0.59, 0.96) | 0.81 (0.61, 1.09) |
| Tertile3 (n = 2,984) | 0.64 (0.48, 0.84) | 0.56 (0.42, 0.76) | 0.64 (0.46, 0.91) |
In sensitivity analysis, fiber intake was converted from a continuous variable to a categorical variable (tertile). OR, odds ratio; 95% CI, 95% confidence interval.
Tertile1, 7.51 ± 0.07 g/day; Tertile2, 14.90 ± 0.05 g/day; and Tertile3, 28.79 ± 0.25 g/day.
Model 1: Adjusted for no covariates.
Model 2: Adjusted for age, sex, and race.
Model 3: Adjusted for age; sex; race; marital status; educational level; PIR; BMI; smoking status; systolic blood pressure; diastolic blood pressure; glucose, cholesterol, triglyceride, HDL, and glycohemoglobin levels; energy intake; vigorous activity; diabetes; hypertension; hypercholesterolemia; sleeping disorder; and hypoglycemic, antihypertensive, lipid-lowing, and aspirin drugs.
