Helping babies who are at risk of becoming obese

More than a third of children in the UK are overweight or obese.1 Worldwide, over 40 million children under five are affected.2 Being obese puts children at risk of serious health problems. For example, children who are obese are more prone to breathing difficulties, fractures and high blood pressure. They can also have early signs of heart disease and diabetes. Professor Lucilla Poston, of King’s College London, is investigating how expectant mothers’ own weight during pregnancy affects their babies. She hopes to find new ways to help prevent childhood obesity that start working before a child has even been born.

How are babies’ lives affected now?

“Being obese can badly affect children in many ways,” says Professor Poston. “Children who are obese can develop health problems during childhood, including diabetes and liver disease. They often don’t do as well as other children at school and are more likely to be bullied. They are also likely to carry on being obese when they grow up.”

“Lower levels of physical activity and easy availability of cheap, high-calorie foods are widely thought to be responsible for childhood obesity, but attempts to change these things have, with a few notable exceptions, had limited success,” adds Professor Poston.

A growing body of evidence suggests children are more likely to be obese if their mother was obese during pregnancy. It’s important to study this further if we are to find better ways to tackle the obesity epidemic – one in five pregnant women in the UK is obese at the time of the first antenatal booking.3

How could this research help?

“We aim to help expectant mothers who are obese during pregnancy,” says Professor Poston. “We’re studying why babies who are ‘exposed’ to their mother’s obesity while in the womb may grow up fatter than the children of thin women – and how we might prevent this.”

“Our research shows giving lifestyle advice to pregnant women who are obese can help them to improve their diet, take a little more exercise and put on less weight during pregnancy,” adds Professor Poston. “What’s more, the women’s babies are thinner at six months of age.”

“In this project, we’re studying blood samples taken from babies at birth to learn how obesity during pregnancy may predispose babies to carry more weight at six months of age, and how changes to the mothers’ lifestyle might help. Identifying the mechanisms involved could enable us to develop new ways to prevent childhood obesity that start working before a child has even been born.”
