Table 3 Multiple linear regression models for associations between weight status and HRQoL, with gender and age

	Model 1		Model 2		Model 3
	n = 944		n = 889		n = 889
Variables	B coef (SE)	95% CI	B coef (SE)	95% CI	B coef (SE)	95% CI
Weight status (ref: healthy weight)	-0.02 (0.01)	-0.05, 0.01	-0.02 (0.01)	-0.05, 0.01	0.00 (0.01)	-0.02, 0.04
Gender (ref: male)			-0.03 (0.01)	-0.05, 0.00*	-0.01 (0.01)	-0.04, 0.01
Age (ref: younger)			-0.02 (0.01)	-0.04, 0.00^#	-0.02 (0.01)	-0.04, 0.00^{^}
Socio-economic status (ref: low disadvantage)			0.00 (0.00)	0.00, 0.00	0.00 (0.00)	0.00, 0.00
Weight status by gender (ref: healthy weight males)					-0.06 (0.03)	-0.11, -0.00^§
Weight status by age (ref: healthy weight younger)					-0.00 (0.03)	-0.06, 0.06

Regression B coefficients (unstandardized) represent differences in total AQoL score compared with reference group (ref). All models adjusted for clustering by school (n = 23). Model 2 and 3 were also adjusted for socio-economic status. *p = 0.026, ^#p = 0.022, ^{^}p = 0.046, ^§p = 0.045.
