Table 4. The odds ratio of the presence of ketonuria according to the metabolic and obesity types.

Variables		Model 1	Model 2
Men (n = 7,941)
	MHNW (n = 4,063)	1 (Reference)	1 (Reference)
	MHO (n = 1,538)	0.895 (0.681–1.177)	0.866 (0.608–1.233)
	MUNW (n = 637)	0.594 (0.391–0.903)	0.815 (0.485–1.368)
	MUO (n = 1,485)	0.484 (0.356–0.658)	0.391 (0.254–0.601)
Women (n = 11,095)
	MHNW (n = 6,582)	1 (Reference)	1 (Reference)
	MHO (n = 1,622)	0.649 (0.488–0.864)	0.698 (0.486–1.002)
	MUNW (n = 866)	0.258 (0.156–0.426)	0.467 (0.226–0.966)
	MUO (n = 1,456)	0.375 (0.266–0.528)	0.801 (0.512–1.254)

Values represent the odds ratio with a 95% confidence interval by logistic regression under complex sample analysis. Model 1: before adjustment. Model 2: after adjustment with age, AST, ALT, daily fat intake, daily protein intake, daily sleep time, alcohol drinking status, current smoking status, practice of aerobic exercise and education level for men and after adjustment with age, AST, ALT, daily fat intake, daily protein intake, daily sleep time, alcohol drinking status, current practice of aerobic exercise, education level, using oral contraceptives and menopause status for women. The bold number is the odds ratio, which does not include 1 in confidence interval.

MHNW = metabolically healthy normal weight, MHO = metabolically healthy obese, MUNW = metabolically unhealthy normal weight, MUO = metabolically unhealthy obese, AST = aspartate aminotransferase, ALT = alanine aminotransferase.
