Babies of mothers with a higher pre-pregnancy body mass index (BMI) are fatter and have more fat in their liver, a study published in September's issue of the journal Pediatric Research has found. The researchers from Imperial College London say that the effect of a mother's BMI on her child's development in the womb might put them on a trajectory towards lifelong metabolic health problems. The research team used magnetic resonance scanning to assess 105 babies born at Chelsea and Westminster Hospital. The babies were scanned while they were asleep to measure the amount of fat in their liver cells, the total amount of fat in their bodies and its distribution. They found that liver cell fat in the babies and total fat, particularly around the abdomen, increased across the entire range of BMI in their mothers. Children of overweight and obese mothers are already known to have a higher risk of being overweight and obese themselves, and of experiencing associated metabolic health problems such as type-2 diabetes. The authors of this new study suggest that the changes they found in babies' bodies might be signs of the first biological changes which, combined with an unhealthy lifestyle, might put babies of overweight mothers on a path to ill health in later life.
