	Unadjusted model^a		Adjusted model^b		Adjusted+BW model^c
	β (SE)	p-value	β (SE)	p-value	β (SE)	p-value
Waking cortisol (mmol/L)	-0.10 (0.06)	0.122	-0.11 (0.06)	0.072	-0.11 (0.06)	0.094
Evening cortisol (mmol/L)	0.11 (0.09)	0.192	0.11 (0.09)	0.216	0.13 (0.09)	0.144
Cortisol awakening response (mmol/L)	0.57 (0.45)	0.202	0.52 (0.45)	0.247	0.46 (0.46)	0.313
Diurnal cortisol slope (mmol/L/hours)	0.06 (0.03)	0.035	0.06 (0.03)	0.032	0.07 (0.03)	0.026

Adjusted only for times of cortisol measurement

Adjusted for times of cortisol measurement, current BMI, height, household income, assets, crowding, and self-reported stress on day of saliva collection

Adjusted model + individual's birth weight
