Snoring pregnant women at higher risk for gestationa...( CHICAGO --- If you are pregnant and ...),Health

CHICAGO --- If you are pregnant and your mate complains your frequent snoring is rattling the bedroom windows, you may have bigger problems than an annoyed, sleep-deprived partner.

A new study from researchers at the Northwestern University Feinberg School of Medicine has found that women who reported frequent snoring during their pregnancy were more likely to develop gestational diabetes -- a condition than can cause health problems for the mother and baby. The study also found pregnancy increases the likelihood that a woman will snore.

This is the first study to report a link between snoring and gestational diabetes.

For the study, 189 healthy women completed a sleep survey at the time of enrollment (six to 20 weeks gestation) and in the third trimester.

Pregnant women who were frequent snorers had a 14.3 percent chance of developing gestational diabetes, while women who did not snore had a 3.3 percent chance. Even when researchers controlled for other factors that could contribute to gestational diabetes such as body mass index, age, race and ethnicity, frequent snoring was still associated with the disease.

Principal investigator Francesca Facco, M.D., a fellow at Northwestern's Feinberg School, will present her findings at the SLEEP 2009 23rd Annual Meeting of the Associated Professional Sleep Societies June 11.

"Sleep disturbances during pregnancy may negatively affect your cardiovascular system or metabolism," said Facco, who in August will become an assistant professor of obstetrics and gynecology at the Feinberg School and a maternal and fetal medicine physician at Northwestern Memorial Hospital.

"Snoring may be a sign of poor air flow and diminished oxygenation during sleep that can cause a cascade of events in your body," Facco said. "This may activate your sympathetic nervous system, so your blood pressure rises at night. This can also provoke inflammatory and metabolic changes,
