Logistic regression models to evaluate the association of overweight in children with timing of solid food introduction; sensitivity analyses by duration of exclusive breastfeeding

Solid food introduction	Formula fed only	Exclusive BF 1–3 months	Exclusive BF 4–6 months
Model 1	n = 1,736	n = 2,521	n = 4,918
1–3 months	0.78 (0.58–1.05)	0.67 (0.53–0.85)
4–6 months	1 (ref)	1 (ref)	1 (ref)
7–12 months	1.01 (0.75–1.61)	1.05 (0.70–1.59)	1.35 (1.02–1.79)
Model 2	n = 1,341	N = 1,990	n = 4,153
1–3 months	0.88 (0.62–1.24)	0.63 (0.47–0.84)
4–6 months	1 (ref)	1 (ref)	1 (ref)
7–12 months	1.02 (0.65–1.61)	1.01 (0.62–1.66)	1.38 (1.01–1.88)

Note. BF = breastfeeding.

Model 1: adjusted for age, sex, and country.

Model 2: adjusted as in model 1 and additionally for birth weight, parental highest level of education (cat), tobacco use in pregnancy (cat), self‐reported maternal body mass index (BMI), self‐reported paternal BMI, gestational diabetes (cat), and maternal gestational weight gain.
