Factors	Model One				Model Two
	Exp (B)	95.0% CI for Exp (B)		p Value	Exp (B)	95.0% CI for Exp (B)		p Value
		Lower	Upper			Lower	Upper
Dietary pattern (reference: Cluster Three)
Cluster One	1.995	1.542	2.581	<0.001	1.356	0.972	1.893	0.073
Cluster Two	2.677	1.816	3.944	<0.001	1.601	1.000	2.563	0.050
Residential area (reference: Metropolitan)
Rural	0.667	0.480	0.926	0.016	1.004	0.680	1.482	0.984
Urban	0.748	0.540	1.037	0.081	0.877	0.601	1.282	0.498

CI: confidence interval. p values were determined by complex sample multiple logistic regression analysis. Cluster One: diet dominant in fruits and fish; Cluster Two: diet dominant in meats; Cluster Three: diet dominant in white rice and kimchi. Model One was unadjusted, but, involved of dietary pattern and residential area together. Model Two was adjusted for gender (men = 1, women = 0), age (continuous), marital status (living alone = 1, living together = 0), education (≤elementary school = 3, middle school = 2, high school = 1, ≥college = 0), income (low = 3, low-medium = 2, high-medium = 1, high = 0), muscular exercise (no = 1, yes = 0), smoking status (current smoking = 1, past / non-smoking = 0), high-risk drinking (no = 1, yes = 0), hypertension (no = 1, yes = 0), diabetes mellitus (no = 1, yes = 0), dyslipidemia (no = 1, yes = 0), arthritis (no = 1, yes = 0), and body mass index (continuous).
