The look found the risk applies even to normal weight babies weighing between 5.5 to 8.8 beat outs at birth and suggests obesity gets ssed on in the womb.
Previous go inti found excess weight gain and elevated blood sugar during pregnancy broaden a woman’s risk of delivering a large baby who is more likely to develop an obese child.
But until now there wasn’t much evidence that these gamble factors also affected normal-weight babies.
Children of mothers who had high blood sugar during pregnancy were at higher risk for babyhood obesity.
But for children of mothers who had gestational diabetes — the highest level of sublime blood sugar — were at the greatest increased risk.
Those youngsters were at least 30 per cent more likely to be overweight or fat between the ages of two and 10, com red to children whose mothers had usual blood sugar.
Children of mothers who gained 40 pounds or uncountable during pregnancy were at least 15 per cent more odds-on to be overweight or obese between the ages of two and 10, com red to children whose matriarches gained less than 40 pounds.
The Kaiser Permanente Cluster for Health Research study, based in the US, followed more than 24,000 progenitrices and their children over 10 years.
All of the mothers gave origin to normal weight babies between 1995 and 2003. The mother’s medical recordings were com red to their child’s records.
Lead author clinical buddy professor Dr Teresa Hillier said: «When women be experiencing elevated blood sugar and gain excess weight during pregnancy, it have all the hallmarks to change the baby’s metabolism to ‘imprint’ the baby for childhood obesity.
«We’re not stable yet of the exact mechanism of this change, but it appears the baby is adapting to an overfed milieu, whether from glucose or extra weight.»
She added many other behavioural and environmental intermediaries contribute to childhood obesity, including the baby not being breastfed, a baby’s poor eating and exercise habits, and lack of access to healthy breads and safe areas to play.
More than one-third of US babies last wishes as become overweight or obese as children and adolescents, according to the Centers for Sickness Control and Prevention.
She not this study showed that the effect in the womb on the pet’s metabolism may be as important as what happens after the child is born.
Professor Hillier, endocrinologist state: «We can’t wait until the baby is born to determine and address the collision on childhood obesity.
«We need to intervene during the mom’s pregnancy to help her with nutritional and lifestyle switches that will result in healthy weight gain, healthy blood sugar and finally, healthy children.»
The study was published in Maternal and Child Health Yearbook.
