Maternal health key to prevention of childhood obesity

Maternal health key to prevention of childhood obesity

A new study from the University of Southampton adds to a growing body of evidence that links a child's early environment before and soon after birth to their chance of becoming obese later in life.

Previous studies have identified a number of individual early life 'risk factors' but few have evaluated the size of their combined effects.

According to EurekAlert, the new research suggests that having a greater number of these risk factors is a strong predictor of being overweight or obese in childhood.

Scientists from the University of Southampton looked at five early life obesity risk factors: a short duration of breastfeeding (less than one month) and four maternal factors during pregnancy — obesity, excess pregnancy weight gain, smoking, and low vitamin D status.

The research shows at age four, children with four or five of these factors were 3.99 times more likely to be overweight or obese than children who had experienced none, and fat mass was, on average, 19 percent higher.

By age six, the risk increased so that these children were 4.65 times more likely to be overweight or obese and fat mass was 47 percent higher. Importantly, these differences were not explained by other factors, such as the children's quality of diet or physical activity levels.

The data analyzed came from 991 children taking part in the Southampton Women's Survey - one of the largest studies of mothers recruited before pregnancy, along with their infants and children.

Findings suggest that interventions to prevent obesity need to start earlier, even before conception, and that having a healthy body weight and not smoking at this time could be key.
