Breastfeeding in the Modern World.

Area of Science:

• Public Health
• Pediatrics
• Oncology

Background:

• 20th-century social changes led to decreased breastfeeding rates, particularly in wealthier nations.
• Concerns over declining breastfeeding prompted research into its health benefits and protective mechanisms for mothers and children.
• International initiatives like the WHO Code of Marketing of Breastmilk Substitutes and the Innocenti Declaration have promoted breastfeeding.

Purpose of the Study:

• To synthesize evidence on the health benefits of breastfeeding for infants and mothers.
• To quantify the impact of breastfeeding on child mortality and maternal health outcomes.

Main Methods:

• Meta-analyses of numerous studies were reviewed.
• Data were analyzed to assess benefits across different socioeconomic and environmental settings.
• The Lives Saved Tool was utilized to estimate mortality reductions.

Main Results:

• Breastfeeding significantly reduces diarrhea, respiratory infections, and mortality in low-income settings.
• In high-income settings, it protects against otitis media, type 2 diabetes, overweight/obesity, and possibly type 1 diabetes.
• Breastfeeding is associated with a 2-3 point IQ increase in children and reduced breast and ovarian cancer risk in mothers.

Conclusions:

• Breastfeeding provides substantial, measurable health benefits for children and mothers globally.
• These benefits translate to significant potential reductions in child and maternal mortality.
• Continued support and promotion of breastfeeding are crucial for public health.
