Babies born big likely to become obese
Parents may help prevent weight gain
CHARLOTTESVILLE, Va, July 17: Infants born with a high birthweight are more likely to become obese as children, a new study from the University of Virginia Children’s Hospital suggests. The researchers say pediatricians may want to counsel parents of high birthweight babies early on to prevent the onset of obesity and the health problems it eventually brings.
The study looked at 10,186 children across the country, both those born at term and those born prematurely. The children born with high birthweight at term were more likely to be obese by kindergarten than their average-weight counterparts. A similar finding held true in the children born prematurely, starting in first grade.
“Infants born with higher birthweight appeared to be at risk from a young age,” researcher Sarah Miller said. “These children may benefit from early attention.”
Children born with a large birthweight (above 10 pounds at term) were 69 percent more likely than average weight children to be obese by kindergarten and continuing at least through second grade, the researchers determined. By second grade, the last grade examined, 23.1 percent of children born with high birthweight were obese. In comparison, children born at the expected weight had an obesity rate of only 14.2 percent by second grade.
Of the premature infants born with high weight for gestational age, 27.8 percent were obese by second grade. Those born at the expected weight had an obesity rate of only 14.2 percent. Those born below the expected weight had an obesity rate of 28 percent.
The study found these relationships despite adjusting for factors such as socioeconomic status, but they did not look at other factors that contribute to the children’s obesity.
