Simple Measures May Curb Excessive Weight Gain in Pregnancy

FRIDAY, July 20 (HealthDay News) — Healthy eating and low or moderate
levels of exercise during pregnancy can help a woman avoid excessive
weight gain and may reduce her infant’s risk of being overweight or obese
later in life, new research indicates.

The study included 49 women at 16 to 20 weeks of pregnancy who were
assigned to either a low- or moderate-intensity walking program. Both
groups also followed a meal plan based on guidelines given to expectant
mothers with gestational diabetes.

The women were compared with another group of pregnant women who were
not assigned to any exercise or diet programs (the “control” group).

All the women in the study were deemed to have a normal, healthy weight
before their pregnancy, the researchers noted in the report, which was
published in the August issue of the journal Medicine Science in
Sports Exercise
.

Compared to the women in the control group, those in the two
exercise/healthy-eating groups gained less weight during pregnancy and
were less likely to gain excessive weight, the investigators found. Within
two months of delivery, 28 percent of women in the moderate-intensity
exercise program were within about 4.4 pounds of their pre-pregnancy
weight, compared with 7 percent of those in the control group.

Babies born to women in all the groups had similar birth weights, which
suggests that preventing excessive weight gain during pregnancy does not
influence infant birth weight, the study authors noted in a news release
from the American College of Sports Medicine.

The researchers pointed out, however, that pregnancy is an important
period in determining a child’s health later in life and preventing
excessive weight gain in pregnancy may reduce a child’s long-term risk for
obesity.

“Women benefit greatly from being active throughout their pregnancies
and physical activity is strongly recommended by professional
organizations,” lead author Stephanie-May Ruchat, a postdoctoral fellow at
the University of Western Ontario in Canada, said in the news release.
“However, most pregnant women remain inactive and this may be contributing
to excessive gestational weight gain, which is associated with an
increased risk for future obesity in both the mother and offspring.”

“Myths about nutrition in pregnancy can also be misleading. For
example, mothers-to-be should be warned that ‘eating for two’ does not
mean they need to eat twice as much, but that they should eat twice as
healthy,” Ruchat noted. “An increase of only 200 to 500 kilocalories per
day in the second and third trimester is recommended, depending on the
body-mass index of the women prior to pregnancy. The heavier the woman is,
the fewer extra calories per day she will need during pregnancy.”

Before beginning any new diet or exercise regimen, experts recommend
discussing it with your doctor or other health professional.
