Association between breastfed status (predictor, categorical) and growth (outcome, change in body weight from previous timepoint) at 8 , 25, and 61 months in the Children in Focus subset.

		Outcome: Difference in mass (kg)
		Model 1 (initial mass + sex)		Model 2 (all confounders)
Growth period	Breastfed type (predictor)	Beta (95% CI)	p Value	Beta (95% CI)	p Value
0–8 m	Not breastfed	(reference)		(reference)
	Breastfed <6 months	0.06 (−0.09, 0.20)	0.5	0.03 (−0.13, 0.18)	0.7
	Breastfed ≥6 months	−0.41 (−0.56, −0.26)	<0.0001	−0.41 (−0.57, −0.24)	<0.0001
8–25 m	Not breastfed	(reference)		(reference)
	Breastfed <6 months	0.09 (−0.08, 0.26)	0.3	0.06 (−0.11, 0.24)	0.5
	Breastfed ≥6 months	0.16 (−0.02, 0.34)	0.08	0.19 (0.00, 0.38)	0.051
25–61 m	Not breastfed	(reference)		(reference)
	Breastfed <6 months	0.14 (−0.22, 0.49)	0.5	0.25 (−0.11, 0.61)	0.2
	Breastfed ≥6 months	0.14 (−0.22, 0.50)	0.5	0.38 (0.00, 0.76)	0.05

The baseline model also included mass at the start of the period and sex, whereas the full model included potential confounding covariates of maternal prenatal anxiety, maternal smoking, maternal age, maternal parity, maternal education, and maternal BMI.
