KIDS' STUFF BREAST IS BEST! BUT WHY…? AUTHOR Mary Elizabeth Dedman, MD E veryone has heard the catchphrase, “Breast is best,” implying that in choos- ing to breastfeed her infant, a mother is providing the ultimate nutrition for her young child. It makes sense, right? No breast milk substitute company could design a more perfect food for one mother’s individual baby than the mother herself. After all, she carried this infant in her womb for all of his or her creation. As physicians, we know that maternal breast milk is the best possible choice for infant nutrition. But the challenges that sometimes come with nursing, especially for a first-time mother, can cause maternal stress that might cut the breastfeeding relationship short. But, if mothers are aware of the vast benefits of breastfeeding, they are more likely to choose to seek help and work through their difficulties than to turn to commercial infant formulas. Physicians, either in a professional work setting or in a relaxed social setting, have a unique opportunity to give, at minimum, a few facts and the verbal support to encourage these mothers and reassure them that the benefits of breastfeeding make it worth the challenges. The American Academy of Pediatrics recommends exclusive breastfeeding for the first six months of life, then continued breastfeeding with the introduction of complementary foods until at least a year of age. Most of the benefits of breastfeeding are achieved with as few as four months of exclusive breastfeeding, but the longer the nursing relationship endures, the higher the benefit for baby. The medical advantages when a baby receives maternal breast milk are very significant. Studies have shown a 72% decrease in the risk of hospitalization for infants with lower respiratory tract infections in the first year of life. Breastfeeders have a 74% decreased severity of respiratory syncytial virus with regard to duration of hospital stay and supplemental O2 requirement. Breastfed infants enjoy a 23-50% decreased risk of otitis media, depending on duration of nursing, and a 63% decrease in upper respiratory infections. A 64% decreased incidence of gastrointestinal infections rounds out the infectious disease benefits of nursing due to the antibodies found in maternal breast milk. which has been shown to be the most important risk factor in SIDS prevention. It is estimated that over 900 infants lives could be saved in the United States each year if we could achieve a breastfeeding rate of 90% for the first six months of age. There is a decreased risk of asthma, allergies and eczema by at least 27% as well as a 15-30% reduction in adolescent and adult obesity rates in babies who are breastfed for any duration. Children who are breastfed generally achieve higher IQ scores and higher teacher ratings during their school years and higher school attainment overall. This has been shown to lead to 12% higher earnings later in life. The neurode- velopmental benefits are especially pronounced in preterm infants, making maternal human milk use in the neonatal intensive care unit very important. Decreased rates of celiac disease, inflammatory bowel disease, necrotizing enterocolitis, type I and II diabetes, and childhood leukemia and lymphoma have also been demonstrated. The baby is not the only recipient of medical advantages in a strong nursing relationship. The maternal benefits of breastfeeding are very significant and seem to be attained through cumulative months of breastfeeding during a mother’s lifetime. Mothers who breastfeed have a decreased incidence of cardiovascular disease, hypertension, hyperlipidemia, diabetes, and rheumatoid arthritis. Women who breastfeed longer than 12 months cumulatively in their lifetime have a 28% decreased risk of breast cancer and ovarian cancer. Breastfeeding also reduces a mother’s risk of postpartum depression. Recommending breastfeeding to mothers as the sole nutrition for their infants is an important role that we as physicians can play. We should also promote support for breastfeeding mothers from their husbands and families. We should maximize the friendliness of the workplace to breastfeeding by providing private rooms for pumping and adequate time in our staff ’s schedules to accommodate this. We should also limit the influence of breast milk substitutes through advertising and sampling to new mothers. We should encourage all of our patients, family members and friends to take advantage of the benefits of breastfeeding for both mother and baby.
