Dr. Eleanor Bimla Schwarz and colleagues from the University of Pittsburgh Medical Center, reported that breastfeeding seems to lower the risk of women toward the aortic calcification or coronary artery and carotid artery plaque. In this study found that mothers who do not breastfeed their babies tended to have a 3-fold early signs of heart disease than breast-feeding mothers.

Therefore, it is important to support mothers to breastfeed for at least the first three months of life. This study is a cross-sectional analysis on 297 women who had at least one live birth. All the women were aged between 45-58 years old and has no clinical signs of cardiovascular disease. The result is 31% mother did not breastfeed her baby. Mothers who do not breastfeed have higher rates of coronary artery calcification (32% vs. 17%), aortic calcification (39% vs. 17%), and carotid plaque (18% vs. 10%). This group also has an average diameter of the carotid adventisia layer thicker.

Although he has made corrections to the factor of socioeconomic status, lifestyle, and family history, mothers who never breast-feeding still have a higher risk for aortic calcification (risk ratio 3.85) and coronary artery calcification (risk ratio 2.78). In a model that takes into account body mass index and cardiovascular disease risk factors, aortic calcification risk ratio in women who are not breastfeeding increased to 5.26. The researchers concluded that the results of this study support the recommendation that mothers breastfeed their babies, good for the health interests of both mother and child health.
