Association between small for gestational age and mild thinness of 6-year-old preschoolers in the logistic regression model.

	BMI of Preschoolers		Crude Model ^a	p-Value	Adjusted Model 1 ^b	p-Value	Adjusted Model 2 ^c	p-Value
	Mild Thinness ^d	Non-Mild Thinness	OR (95% CI)	p-Value	OR (95% CI)	p-Value	OR (95% CI)	p-Value
SGA	28 (21.1)	115 (13.0)	1.78 (1.12–2.83)	0.014 *	1.80 (1.12–2.89)	0.014 *	1.72 (1.07–2.78)	0.026 *
Non-SGA	105 (78.9)	769 (87.0)	1.78 (1.12–2.83)	0.014 *	1.80 (1.12–2.89)	0.014 *	1.72 (1.07–2.78)	0.026 *

Notes: BMI, body mass index; SGA, small for gestational age; OR, odd ratio; CI, confidence interval; ^a Crude model. ^b Adjusted model 1: adjusted for maternal age, pre-pregnancy BMI, parity, gravidity, newborn gender, and gestation age. ^c Adjusted model 2: adjusted for variables in model 1 and five maternal essential metal elements. ^d Mild thinness is defined as body mass index z-score < −1 for 6-year-old preschoolers of different genders. * p < 0.05.
