Birth, Development, and Health

Objective To evaluate the association between breastfeeding duration and early childhood cardiometabolic risk. Study design A cross-sectional study of 1539 healthy children, 3-6 years of age, recruited through The Applied Research Group for Kids! practice-based research network between October 2009 and August 2015. Adjusted multivariable linear regression was used to examine the association between breastfeeding duration and cardiometabolic risk z score and individual cardiometabolic risk factors of waist circumference, systolic blood pressure, glucose, high-density lipoprotein cholesterol, and triglycerides. Results The mean breastfeeding duration was 12.5 months (SD = 8.4). Breastfeeding duration was associated with lower cardiometabolic risk z score (beta = −0.03; 95% CI −0.05, −0.01). In analysis of cardiometabolic risk factors, each additional 3 months of breastfeeding was associated with a 0.13 cm (95% CI −0.20, −0.05) lower waist circumference and 0.16 mm Hg (95% CI −0.30, −0.02) lower systolic blood pressure. Compared with children who breastfed for 6-12 months, those who breastfed for 12-24 months had a lower systolic blood pressure of 1.07 mm Hg (95% CI −2.04, −0.10). There was no association between breastfeeding duration and cardiometabolic risk for those who breastfed beyond 24 months. Conclusions Breastfeeding duration is associated with lower cardiometabolic risk, although the magnitude of association is small. Causation cannot be inferred. Breastfeeding beyond 24 months may not have an added benefit for cardiometabolic health. To evaluate the association between breastfeeding duration and early childhood cardiometabolic risk.
