Summary
Extended infant breast-feeding, over 6 months, was linked to higher cholesterol and atherogenic index in children by age 10. Optimal duration requires further study.
Area of Science:
- Pediatrics
- Nutritional Science
- Biochemistry
Background:
- Longitudinal studies are crucial for understanding the long-term effects of infant nutrition.
- Previous data up to 7 years highlighted the impact of infant feeding practices.
Purpose of the Study:
- To investigate the clinical and biochemical effects of infant nutrition up to age 10.
- To assess the association between breast-feeding duration and cardiovascular risk markers.
Main Methods:
- A longitudinal prospective study followed children from birth to 10 years.
- Clinical examinations and biochemical parameter measurements were conducted.
- Statistical analysis, including chi-squared test, was used.
Main Results:
- Children breast-fed for over 6 months showed significantly higher incidence of elevated atherogenic index and cholesterolemia.
- Two obese children with high blood pressure had short breast-feeding durations (<1 week).
- Serum total cholesterol was highest in the >6 months breast-feeding group; thyroid function was unaffected.
Conclusions:
- While breast-feeding has benefits, durations exceeding 6 months may be associated with adverse effects on lipid profiles.
- Further research is needed to determine the optimal duration of breast-feeding considering all health aspects.
