"However, our results concur with the observations [that] other neonatal factors, such as weight at birth, are positively related to better muscle condition during adolescence."
The study was published recently in the
Journal of Nutrition.
The researchers noted previous studies have shown many other
benefits for infants and children who have been breast-fed,
including increased protection against childhood allergies, skin
diseases, obesity and diabetes.
The U.S. National Women's Health Information Center has more
