BOSTON, Mass. (March 30, 2009) As childhood obesity continues its thirty-year advance from occasional curiosity to cultural epidemic, health care providers are struggling to find out whyand the reasons are many. Increasingly sedentary environments for both adults and children, as well as cheap and ubiquitous processed foods no doubt play a role, but researchers are finding more evidence that the first clues for childhood obesity may begin as far back as early infancy.
A new study led by researchers in the Department of Ambulatory Care and Prevention at Harvard Medical School and Harvard Pilgrim Health Care, as well as Children's Hospital Boston, has found that rapid weight gain during the first six months of life may place a child at risk for obesity by age 3.
"There is increasing evidence that rapid changes in weight during infancy increase children's risk of later obesity," says lead author Elsie Taveras, assistant professor in the HMS Department of Ambulatory Care and Prevention and co-director of the One Step Ahead clinic, a pediatric overweight prevention program at Children's Hospital Boston. "The mounting evidence suggests that infancy may be a critical period during which to prevent childhood obesity and its related consequences."
These findings appear in the April edition of the journal Pediatrics.
Most prior studies examining the relationship between infant weight gain and later childhood obesity focus primarily on body weight. However, measures of length, in addition to weight, together reflect body fatness better than weight alone. In this study, Dr. Taveras and colleagues in the HMS Department of Ambulatory Care and Prevention examined how weight and body length, or weight-for-length, in infancy can influence later obesity.
The team mined self-reported data from Project Viva, an ongoing study led by Matthew Gillman, senior author on the paper, of more than 2,000 pregnant women and their child
