Reduced growth velocity in exclusively breast-fed infants

Area of Science:

• Pediatrics
• Infant Nutrition
• Growth Monitoring

Background:

• Recent studies indicate reduced growth velocity in breast-fed infants compared to standard growth curves.
• Previous research is contradictory due to methodological issues, especially nutrient supplementation.
• The appropriateness of existing growth standards for breast-fed infants requires re-evaluation.

Purpose of the Study:

• To assess the growth patterns of exclusively breast-fed infants.
• To compare the growth of exclusively breast-fed infants with National Center for Health Statistics (NCHS) data.
• To evaluate the adequacy of exclusive breast-feeding for infant growth up to six months.

Main Methods:

• Study included 33 term infants exclusively breast-fed for six months.
• Infant growth (weight and length) was tracked from birth to six months.
• Growth percentiles were compared against NCHS growth data.

Main Results:

• Exclusively breast-fed infants demonstrated significantly slower growth rates than NCHS data.
• Infants lost an average of 20 percentiles in weight-for-age between birth and six months.
• Infants lost an average of 30 percentiles in length-for-age during the same period.

Conclusions:

• The NCHS growth data may not be appropriate as a standard for exclusively breast-fed infants.
• Exclusive breast-feeding may lead to slower growth compared to current standards.
• Further research is needed to establish optimal growth standards for exclusively breast-fed infants.
