Study sheds new light on why breast-fed babies grow more slowly

Breast-fed babies grow more slowly than formula-fed babies, which is why new growth charts, based solely on the growth patterns of breast fed babies, are being introduced in the UK in May. This slower pattern of growth in the first year of life is possibly one reason why breast-fed babies are less likely to become overweight children later on.

A study published on-line today (24 April 2009) in the has found evidence that the lower content of compared to formula milk explains the slower growth rates seen in breast fed infants.

The study was a multi-centre intervention trial in 5 European countries, co-ordinated by Professor Berthold Koletzko from the University of Munich, Germany. Over 1000 infants were randomised to receive infant and follow-on formulas with lower or higher protein content for their first year and were then followed up for 2 years. A group of breast fed infants were also followed up for comparison.

After 2 years, the infants fed the lower protein formula were the same height but weighed slightly less than the infants fed the higher protein formula and were more similar to the group of breast fed . Since there was no difference in height, the difference in weight was probably due to a difference in body fat. Lower protein intakes in infancy therefore might protect against later . The children are being followed up further to see whether those given the lower protein formulas have a reduced risk of obesity later on.

“These results from the EU Childhood Obesity Programme underline the importance of promoting and supporting breastfeeding because of the long-term benefits it brings. They also highlight the importance of the continual development and improvement in the composition of infant formula,” said Professor Koletzko.

“Limiting the protein content of infant and follow-on formula can normalize early growth and might contribute greatly to reducing the long-term risk of childhood overweight and obesity,” continued Professor Koletzko.
