Association of vitamin D concentration with different metabolic phenotypes of obesity in nominal logistic regression: the CASPIAN-V study.

	Metabolic phenotypes of obesity
	MHNO	MHO	MNHNO	MNHO
Vitamin D concentration (ng/mL)
Model I	Reference	0.98 (0.97–0.99)*	0.92 (0.90–0.95)*	0.96 (0.92–0.99)*
Model II	Reference	0.97 (0.97–0.99)*	0.93 (0.90–0.95)*	0.95 (0.92–0.98)*
Model III	Reference	0.99 (0.98–1.01)	0.93 (0.91–0.96)*	0.94 (0.91–0.98)*

Model I: crude association; Model II: adjust for age, sex, living place; Model III: adjust for ST, PA, SES, vitamin D supplementation.

MHNO, metabolically healthy non obese; MHO, metabolically healthy obese; MNHNO, metabolically non healthy non obese; MNHO, metabolically non healthy obese.

Values are reported as OR (95% CI).

^*Statistically significant (p < 0.05).

OR calculated per each unit (ng/mL) increment in vitamin D concentration.
