Association between duration of total and exclusive breastfeeding and BMI trajectory

	Total breastfeeding				Exclusive breastfeeding
BMI trajectory	Estimate	SE	P value		Estimate	SE	P value

BMI trajectory defined by Ziyab et al. [42]. Columns: trajectory 2 = early persistent obesity, trajectory 3 = early transient overweight, trajectory 4 = delayed overweight; estimate = coefficient denoting one-unit (in week) increase in breastfeeding duration is associated with the increase in the log odds of being in BMI trajectory; standard error = standard error of coefficient. P value < 0.05 was considered significant and is indicated by *. Each trajectory was tested against the control group (BMI trajectory 1)
