Too Much Weight Gain in Pregnancy Linked to Chubby
TUESDAY, June 7 (HealthDay News) -- Women who gain an excessive
amount of weight during pregnancy tend to have chubbier babies, a
possible risk factor for childhood obesity, new research
The Institute of Medicine recommends that normal weight women
gain 25 to 35 pounds during pregnancy. Overweight women should keep
weight gain between 15 and 25 pounds, while obese women should
limit weight gain to 11 to 20 pounds.
The study included 56 women -- 31 whose pregnancy weight gain
fell within the guidelines and 25 who gained too much. None of the
women had gestational diabetes.
Researchers tested infant's body fat within 48 hours of delivery
using what they say is a newer, more accurate technique.
Babies born to women who exceeded the guidelines had 17.5 ounces
of body fat compared to 13.9 ounces among newborns of women whose
weight gain fell within the guidelines.
Researchers noted the link between pregnancy weight gain and
baby's body fat regardless of the women's weight before becoming
pregnant, although women who were obese before pregnancy were more
likely to exceed the weight gain guidelines.
About 70 percent of obese women exceeded the weight gain
recommendations compared to 31 percent of normal weight women.
The study was to be presented Tuesday at The Endocrine's
Society's 93rd annual meeting in Boston.
"Excessive weight gain during pregnancy, regardless of pre-pregnancy weight, is an important risk factor for newborn obesity," said the study's principal investigator, Dr. Jami Josefson, a pediatric endocrinologist at Children's Memorial Hospital and assistant professor at Northwestern University Feinberg School of Medicine in Chicago, in a news release from The Endocrine Society. "More research is needed to determine if high amounts of fat at birth are associated with high amounts of fat in childhood."
Because this study was presented at a medical meeting, the data
and conclusions should be viewed as preliminary until published in
a peer-reviewed journal.
The National Women's Health Information Center has more
complications during pregnancy.
