Heavy moms less apt to breastfeeding

Updated: 2006-09-19 09:30 NEW YORK - Overweight and obese women are less
likely than normal-weight women to keep breastfeeding their infants for six
months or longer, a study from Australia shows.
Dr. Wendy Hazel Oddy of the Telethon Institute for Child Health Research in
Perth and colleagues looked at 1,803 children and their mothers participating in
a large pregnancy study. Eighteen percent of the women were overweight or obese
before becoming pregnant.
After the researchers adjusted for factors including socioeconomic status and
years of education, they found that women who were overweight or obese were less
apt to attempt breastfeeding at all and those that did were less likely to
continue breastfeeding.
Obese women were about twice as likely to have breastfed for less than two
months or less than four months, while overweight women were 52 percent more
likely than normal weight women to have stopped breastfeeding before two months,
and 62 percent more likely to have stopped before four months.
Overall, the researchers found, overweight or obese women were 76 percent
more likely to stop breastfeeding before their infants were six months old than
their normal weight peers.
A number of factors could help explain the findings, the investigators say.
For example, excess weight may change a woman's hormonal profile, making
sustained lactation more difficult, or it may be harder for an infant to "latch
on" to breast tissue if the mother is overweight or obese.
The researchers also report that overweight and obese women were more likely
to have pregnancy complications and C-sections than normal-weight women.
