People who realize they are overweight often struggle to begin
or maintain a weight-loss program; frequently, a sense of
futility can emerge when the realization hits that losing
weight is not a fun or easy
thing to do. As a result, some of these individuals give up
and become content with their weight. A recent study in Pediatrics
shows that women attempting to have a child may not have this
option.
A team at the Centers for Disease Control and Prevention
(CDC) in Atlanta looked at risks for several major birth defects
based on nearly 1,000 area pregnancies between 1993 and 1997,
over 600 of which were selected because of a known birth defect.
The body mass index (BMI) of each mother, a measure used to
determine if a person is overweight or obese, was calculated
to determine birth-risk differences between obese and normal-weight
mothers.
Women considered obese when they became pregnant were more
than three times more likely to have a baby with spina bifida
(a defect involving incomplete development of the vertebrae
and exposure of the spine) or an abdominal deformity called
an omphalocele than healthy-weight mothers. Both obese mothers
and even mothers only considered overweight were twice as
likely to have an infant with heart defects or multiple, unrelated
birth defects.
Abnormal metabolic processes or undiagnosed diabetes common
in obese women may be responsible for the development of birth
defects in a fetus. If you are considering having a child,
but are overweight, try to get down to a healthy weight before
conceiving. Not only will you benefit physically and emotionally
- so will your unborn child.
