Sleep Apnea May Increase The Risk Of Adverse Pregnancy Outcomes
Posted Oct 15 2013 7:06am
Obstructive sleep apnea (OSA) is a common condition among Americans. This is well evident as one in 15 Americans suffers from this condition these days. A new study states that women who have OSA are highly prone to high risk health conditions during pregnancy, which is fatal to their babies and the mothers. The study said that those babies that were born to women with OSA condition are more likely to be admitted to the neonatal intensive care unit than those babies that are delivered by healthy mothers.
Details of the study
The study was conducted on obese women who were pregnant. The study revealed that the were more prone to develop preeclampsia, which is a serious condition of high blood pressure during pregnancy, where an emergency caesarean section may be required. The complications during pregnancy of obese women were also linked to high blood pressure and gestational diabetes. These two medical conditions are always understudied and under-diagnosed in women who are pregnant, according to the researchers. The study researcher and Assistant Professor of Obstetrics and Gynecology at the University of South Florida, Dr. Judette Louis, said that there is a need for better methods to test for and treat sleep apnea among women during their pregnancy.
Nature of Sleep Apnea
Usually, people who experience this condition gasp for air while sleeping. Women who are overweight face a higher risk of experiencing this condition, as fat in the throat can narrow the airway and can cause difficulty breathing at night.
Findings of the study
In this new study, researchers analyzed the condition of over 175 obese women who were pregnant and were screened for OSA in their homes by offering them a small portable device. About 15% of participants were found to have OSA. These participants were a bit heavier and had higher blood pressure levels than those who did not have OSA. Among those pregnant women who had OSA, about 65% needed a caesarean section while 33% of those without this condition needed a C-section to deliver their baby.
In addition, the study revealed that 42% of those with sleep apnea had preeclampsia when compared to 17% of those who did not have this condition. However, the premature birth rate was similar between the groups involved in the study. The percentage of newborn babies that required admission to NICU was 46% of the mothers who had OSA. This is much higher when compared to the 18% of those mothers who did not have sleep apnea. Researchers feel this might be because of the high rate of the caesarean births among the group of women who have sleep apnea. However, it is not clear on the effects of sleep apnea among women who are not obese as this study focuses on obese women.
