Breastfeeding is associated with reduced risks of central obesity and hypertension in young school-aged children: a large, population-based study

Table 2 Linear regression of any breastfeeding or exclusive breastfeeding duration with BMI, WC, SBP, and DBP values among children in their first grade in primary school

	Crude model		Full model
	β (95% CI)	P-value	β (95% CI)	P-value
Duration of any breastfeeding (in months)
BMI (kg/m²)	-0.01 (-0.02, 0.00)	0.03	-0.01 (-0.02, 0.00)	0.07
WC (cm)	-0.03 (-0.05, 0.00)	0.02	-0.01 (-0.02, 0.01)	0.49
SBP (mmHg)	-0.10 (-0.14, -0.06)	< 0.01	-0.07 (-0.11, -0.03)	< 0.01
DBP (mmHg)	-0.06 (-0.09, -0.03)	< 0.01	-0.05 (-0.08, -0.02)	< 0.01
Exclusive breastfeeding duration (in months)
BMI (kg/m²)	-0.02 (-0.04, 0.00)	0.06	-0.02 (-0.04, 0.00)	0.09
WC (cm)	-0.08 (-0.12, -0.03)	< 0.01	-0.02 (-0.05, 0.01)	0.14
SBP (mmHg)	-0.09 (-0.17, -0.01)	0.02	0.00 (-0.08, 0.08)	0.91
DBP (mmHg)	-0.04 (-0.10, 0.01)	0.11	-0.01 (-0.07, 0.05)	0.73

CI: confidence interval; BMI: body mass index; WC: waist circumference; SBP: systolic blood pressure; DBP: diastolic blood pressure
Duration of any breastfeeding: the number of months for any breastfeeding; Exclusive breastfeeding duration: the number of months for exclusive breastfeeding
The breastfeeding duration ranged from zero to 24 months of age; the exclusive breastfeeding duration ranged from zero to six months of age
Full model adjusted for sex, age at the health check, birth weight, delivery mode, maternal age, and parental education levels. For the outcomes of WC and BP, we also adjusted the BMI value obtained at the children’s first school health check
