Breastfeeding and Maternal Health Benefits
Yes, breastfeeding significantly reduces a mother's risk for breast cancer, ovarian cancer, type 2 diabetes, and cardiovascular disease including hypertension, but does NOT reduce the mother's risk for respiratory infections—respiratory protection is a benefit for the infant, not the mother. 1, 2
Maternal Cancer Risk Reduction
Breastfeeding provides substantial protection against breast and ovarian cancers:
- Breast cancer risk is reduced by 19% (OR 0.81,95% CI 0.77-0.86) in mothers who breastfeed 2
- Ovarian cancer risk is reduced by 30% (OR 0.70,95% CI 0.64-0.75) 2
- These protective effects are dose-dependent, with longer breastfeeding durations conferring greater risk reduction 1
Cardiovascular Disease and Hypertension Risk Reduction
Breastfeeding significantly reduces maternal cardiovascular disease risk, including hypertension:
- Overall cardiovascular disease risk is reduced by 11% (HR 0.89,95% CI 0.83-0.95) in women who ever breastfed compared to those who never breastfed 3
- Coronary heart disease risk is reduced by 14% (HR 0.86,95% CI 0.78-0.95) 3
- Stroke risk is reduced by 12% (HR 0.88,95% CI 0.79-0.99) 3
- Fatal cardiovascular disease risk is reduced by 17% (HR 0.83,95% CI 0.76-0.92) 3
- The protective effect shows a progressive risk reduction with breastfeeding durations up to 12 months 3
- Breastfeeding is associated with decreased blood pressure and reduced risk of hypertension as part of overall cardiovascular protection 4, 5
Type 2 Diabetes Risk Reduction
Breastfeeding provides robust protection against type 2 diabetes:
- Type 2 diabetes risk is reduced by 32% (OR 0.68,95% CI 0.57-0.82) in mothers who breastfeed 1, 2
- This benefit is particularly pronounced in women with a history of gestational diabetes 1, 2
- The protective effect is enhanced with longer breastfeeding duration 1
Respiratory Infections: Clarifying the Misconception
Respiratory infection protection is an INFANT benefit, not a maternal benefit:
- Breastfeeding reduces respiratory infections in children under 2 years of age, not in mothers 1
- Infants who are breastfed have reduced risk of pneumonia and other respiratory illnesses 1
- There is no evidence that breastfeeding reduces the mother's risk of respiratory infections 1
Duration Recommendations for Optimal Maternal Health Benefits
The American Academy of Pediatrics provides clear guidance on breastfeeding duration:
- Exclusive breastfeeding for approximately 6 months is recommended 1
- Continued breastfeeding for 2 years or beyond (along with complementary foods after 6 months) provides maximal maternal health benefits 1
- Studies confirm that breastfeeding longer than 12 months significantly impacts maternal health by decreasing type 2 diabetes, hypertension, breast cancer, and ovarian cancer rates 1
Common Pitfalls to Avoid
Do not confuse infant benefits with maternal benefits:
- Respiratory infection protection, reduced diarrheal disease, and reduced SIDS risk are infant outcomes, not maternal outcomes 1
- When counseling mothers about breastfeeding benefits, clearly distinguish between maternal health benefits (cancer, diabetes, cardiovascular disease) and infant health benefits (infections, obesity, cognitive development) 1, 4
