Breastfeeding and Public Health

Shortened or absent breastfeeding has enormous public health implications for all segments of society: children and adults, male and female. Below are some statistics:

  • Women who have never breastfed have 1.2-2.8 times the risk of pre-menopausal breast cancer.1 Breast cancer alone kills about 1,600 Massachusetts residents per year, striking about 4,400 people per year.2 About one-quarter of breast cancer deaths are in pre-menopausal women.3 (HIV, by comparison, killed 327 people in 2001).4
  • Two years of lifetime breastfeeding can dramatically lower the risk of pre-menopausal breast cancer. If a woman has two children, and breastfeeds each for a year (the recommended guideline), her risk of pre-menopausal breast cancer is lowered by 28-61%.1 Breastfeeding can lower the risk of any type of breast cancer by 4.3% for every 12 months of breastfeeding.5
  • Women who have never breastfed have 1.25 times the rate of ovarian cancer,1,6 higher rates of endometrial cancer,6,7 as well as osteoporosis and hip fractures.1,8,9 Ovarian cancer kills about 400 people per year in this state.2
  • Infants who were not breastfed have 7 times as much necrotizing enterocolitis (which has a 30% mortality rate);10 twice as many cases of otitis media, higher rates of hospitalization, higher rates of lower respiratory tract illness, gastrointestinal illness, meningitis; 15-18 Sudden Infant Death Syndrome (SIDS)14,19-20; and abandonment by their mothers.21
  • Children who were not breastfed have higher rates of type 1 diabetes mellitus,11,14,22-24 leukemia and lymphoma,11,14,25 dental caries,26 dental malocclusion.27-28
  • Children and adults who were not breastfed as babies have higher rates of Crohn’s disease and ulcerative colitis,11,14,29 and celiac disease.30
  • Massachusetts spends about $27 million/year to treat excessive cases of infant diarrhea, respiratory syncitial virus, and otitis media in formula fed infants.31
  • It is estimated that an average of $331-475 in extra health care costs are incurred per child in the first year of life to treat excessive cases of lower respiratory tract infection, gastrointestinal disease, and otitis media in formula fed infants, compared to infants breastfed for as little as three months.32
  • Nursing mothers miss less work because their children are healthier.33
  • Maternal pre-menopausal breast cancer rates1 and rates of childhood otitis media,17,18 leukemia,25 and type 1 diabetes mellitus 22,23 all go down more with increasing duration of breastfeeding.
  • Although the links between breastfeeding and asthma have been controversial, there remains considerable evidence that children who were not exclusivelybreastfed have 1.4-2.4 times the odds of having asthma.34-37 The prevalence of asthma is 10-30% among children and adolescents.39-43 Further, many children with asthma go on to have adult asthma as well.
