Multiple Logistic Regression of the Association Between Dietary Fiber Intake and Constipation

Variable	Crude model^a		Model I^b		Model II^c

	OR (95% CI)	P-value	OR (95% CI)	P-value	OR (95% CI)	P-value
Dietary fiber^d	0.97 (0.97, 0.98)	< 0.001	0.99 (0.98, 0.99)	< 0.001	0.98 (0.96, 1.00)	0.130
Dietary fiber^e	0.95 (0.93, 0.96)	< 0.001	0.97 (0.96, 0.98)	< 0.001	1.00 (0.97, 1.03)	0.863

^aThis model was not adjusted for any confounding variables.

^bModel I was adjusted for gender, age, ethnicity, marital status, education, income-poverty ratio, and body mass index.

^cModel II was further adjusted for smoking, poor oral health, vitamin D deficiency, depression, diabetes, chronic disease, milk, total fat, carbohydrate, protein, total saturated fatty acids, cholesterol, alcohol, moisture, and physical activity.

Constipation is defined by ^dstool consistency and ^estool frequency, respectively.
