Aug. 9, 2006 -- America's babies are chubbier than they used to be, according to a new study.
The estimates are based on information about 120,000 kids up to 6 years old at a Massachusetts health maintenance organization (HMO) between 1980 and 2001.
"Theepidemic has spared no age group, even our youngest children," researcher Matthew Gilman, MD, says in a Harvard news release.
Gilman is an associate professor at Harvard Medical School's ambulatory care and prevention department. He also works at Harvard Pilgrim Health Care.
The study appears in the July issue of Obesity.
Tots Tipping the Scales
The children's height and weight were recorded at doctor's visits.
Babies and kids typically see doctors fairly often for routine checkups. The researchers noted only one set of measurements for each child per year, to avoid skewing the data.
Here are the results for kids younger than 6 years, including babies:
- Overweight prevalence rose from 6.3% to 10%
- Prevalence of being at-risk-of-overweight increased from about 11% to 14%.
Looking specifically at infants up to 6 months of age, in 1980-1981, 3.4% were overweight, and about 7% were at risk of becoming overweight.
Twenty years later, 5.9% of the babies were overweight, and 11.1% were at risk of becoming overweight.
"Our data demonstrate that overweight is increasing in very young children, including infants," the researchers write.
The study doesn't indicate whether overweight babies became overweight teens and adults, or if they were healthy - just a little hefty.
But other studies have shown that extra pounds often stick around from childhood into adulthood, the researchers note.
Gilman says "efforts to prevent obesity must start at the earliest stages of human development, even before birth."
- Don't smoke or gain too much weight during
- Take steps to prevent
- Breastfeed your baby
Those steps have been shown to give kids a head start to healthy weight, Gilman notes.
A certain amount of "baby fat" is normal. If you're concerned about your child's weight, ask your child's pediatrician for advice.
