Breastfed babies 'cope better with stress'
4 August 2006
Babies who are breastfed can cope better with stress in later life compared with those who are bottle-fed, new research has suggested.
Researchers used data from the 1970 British Cohort Study - a study that regularly monitors a sample of the UK population born in a particular week.
They studied the records of 9000 children who had taken part in this survey, looking in particular at their emotional resilience to traumatic events such as their parents divorcing or separating.
Levels of stress and anxiety were measured in the children at the ages of five and 10. These details were obtained by parents, teachers and health visitors who rated the child's level of anxiety on a scale of 0 to 50.
The results, published in the Archives of Disease in Childhood, showed that children who had been breastfed were "significantly less anxious" than bottle-fed children and so better equipped to deal with the divorce or separation.
Children who had been bottle-fed were found to be nine times more likely to be highly anxious if their parents split up than if they stayed together. Breastfed children were only twice as likely to be highly anxious if their parents split up.
The researchers, from the Karolinska Institute in Stockholm, suggested that breastfed babies may become better equipped to deal with stress because of the close physical contact they have with their mother during their first few days of life. This contact could have an impact on the development of their stress responses.
