Child Health Benefits
Decreased rates of:
• Celiac disease
• Inflammatory bowel disease
• Hypertension
• Hypercholesterolemia
AAP Pediatrics 2012;129;e827-41.
Childhood Obesity
• One of the most significant childhood
health problems in the U.S.
• Affects 20% of children in the U.S., with
up to 30% classified as overweight for
age
• Incidence decreased in the breastfed
population

Breastfeeding and Obesity
• Obesity defined as a BMI > 95%ile for age
• Data from the Pediatric Nutrition Surveillance
System
• 177,304 children followed up to 60 months
• Controlled for gender, ethnicity/race, BW
• Dose-responsive protective effect against obesity at
age 4 years in non-Hispanic whites
• Greatest protection with breastfeeding for > 12
months
Grummer-Strawn LM, Mei Z: Does Breastfeeding Protect Against Pediatric Overweight?
Analysis of Longitudinal Data From the Centers for Disease Control and Prevention Pediatric
Nutrition Surveillance System. Pediatrics 2004;113:81-86.
Obesity Prevention
• Encourage breastfeeding
• “Extent and duration of breastfeeding have
been found to be inversely associated with
risk of obesity in later childhood, possibly
mediated by physiologic factors in human
milk as well as by the feeding and parenting
patterns associated with nursing.”
AAP Policy Statement, Committee on Nutrition, Pediatrics 2003; 112:424-430.
Cognitive Benefits
• Human milk
– Contains fatty acids, nucleotides,
oligosaccharides, and taurine
to enhance neural and retinal
development
– Enables child to reach full
developmental potential
• Human milk fat
– Provides essential fatty acids
– Provides long-chain polyunsaturated fatty acids,
including docosahexaenoic acid
(DHA) and arachidonic acid (ARA)
Breastfeeding Outcomes for
Premature Infants
• Lower rates of
• Improved
– Sepsis
– Leptin and insulin
metabolism
– Nectrotizing enterocolitis
– Neurodevelopmental
– Retinopathy of
outcomes
prematurity
– Metabolic syndrome
– Blood pressure
– Low-density lipoprotein
levels

Maternal Health Outcomes
from Breastfeeding
• Decreased postpartum
bleeding
• More rapid uterine
involution
• Decreased menstrual
blood loss
• Increased child spacing

Maternal Benefits of
Breastfeeding
BF=Breastfeeding
•
•

•
Type 2 diabetes mellitus 4-12% less for each year of
BF for women w/out history gestational DM
Pre-menopausal breast cancer 4.3-28% less for each
year of BF
Ovarian cancer 21% less for any vs. no BF and
evidence for dose response
Postpartum depression less for short term BF vs. no
breastfeeding

risk of
• rheumatoid arthritis

regularly or allowing long
periods without breastfeeding?

The Economic Benefits of
Breastfeeding
• U.S. Department of Agriculture
• $3.6 billion dollars would be saved annually
if US breastfeeding rates increased to that
recommended in Healthy People 2010
guidelines
• Projected figures were based on analysis of
decreased otitis media, gastroenteritis, and
necrotizing enterocolitis cost savings only
J Weimer: U.S.D.A., Food Assistance and Nutrition Research Report No. 13, March 2001
http://www.ers.usda.gov/publications/fanrr13
Burden of Suboptimal
Breastfeeding in the US
• Analyzed saving for those conditions validated by
the AHRQ report:
– necrotizing enterocolitis
– otitis media
– gastroenteritis
– hospitalization for lower respiratory tract infections
– atopic dermatitis
– sudden infant death syndrome
– childhood asthma
– childhood leukemia
– type 1 diabetes mellitus (type 2 DM excluded)
– childhood obesity
Bartick M: The Burden of Suboptimal Breastfeeding in the United
States: A Pediatric Cost Analysis. Pediatrics online April 2010.
Burden of Suboptimal
Breastfeeding in the US
• Results: If 90% of US families could comply with
medical recommendations to breastfeed
exclusively for 6 months, the United States would
save $13 billion per year and prevent an excess
911 deaths, nearly all of which would be in infants
($10.5 billion and 741 deaths at 80% compliance).
• Conclusions: Current US breastfeeding rates are
suboptimal and result in significant excess costs
and preventable infant deaths. Investment in
strategies to promote longer breastfeeding
duration and exclusivity may be cost-effective.
