Breastfeeding 'cuts obesity risk'
Babies who are breastfed for longer and weaned on to solids later are less likely to suffer childhood obesity, a study has revealed.
Researchers found the risk of a nine-year-old being obese was reduced by 51% if breastfed for six months or more, compared with an exclusively formula fed child.
Infants breastfed for three to six months were 38% less likely to be chronically overweight by nine, they added.
The findings are based on the Growing Up in Ireland report, which previously revealed a quarter of nine-year-olds are rated overweight or obese, at 19% and 7% respectively.
Professor Richard Layte said factors including parental weight, status, lifestyle, exercise and diet were also taken into account.
"Obesity is a serious problem in Ireland," said Prof Layte, of the Economic and Social Research Institute (ESRI). "We have some of the highest rates of child and adult obesity in Europe and we need to understand the causes better. Our study suggests that early life nutrition may be a key issue for improving health and reducing obesity."
Growing Up in Ireland is a Government-funded study following the progress of almost 20,000 children from nine months to 13 years.
It found Ireland has the lowest breastfeeding rate in Europe, with 55% of new mothers breastfeeding to some extent. Only 38% still breastfeed after a month and less than 15% for six months.
About 46% of infants are weaned on to solid foods by four months and less than a third are weaned after six months - a guideline set by the World Health Organisation.
Researchers warned obese children are more likely to become obese adults and suffer a range of chronic diseases including coronary heart disease, diabetes and stroke.
