Sleep apnea in pregnancy may harm mom and baby Sep 21st 2012, 11:31 Women who experience sleep apnea during pregnancy may face an increased of risk of health problems, for both themselves and their newborns, a new study suggests. In the study, babies born to women with obstructive sleep apnea were more likely to be admitted to the neonatal intensive care unit than babies born to women without the condition. All of the women in the study were obese. In addition, the women with sleep apnea were more likely to develop preeclampsia, a condition of high blood pressure during pregnancy, and to deliver their babies by cesarean section. Pregnancy complications linked to obesity — such as high blood pressure and gestational diabetes — are better understood than sleep apnea, which is an understudied and under-diagnosed condition in pregnant women, the researchers said. There is a need for better ways to screen and treat sleep apnea in pregnancy, said study researcher Dr. Judette Louis, an assistant professor of obstetrics and gynecology at the University of South Florida. People with sleep apnea experience pauses in their breathing during sleep. With obstructive sleep apnea, the pauses are due to a blocked airway. Obesity increases the risk for obstructive sleep apnea because the extra fat tissue can narrow in the inside of the windpipe, according to the National Heart and Blood Institute. In the new study, the reseachers analyzed information from 175 obese pregnant women who were tested for obstructive sleep apnea at home using a portable device. About 15 percent of participants had obstructive sleep apnea. Those with sleep apnea were more likely to be heavier, and have chronic high blood pressure than those without sleep apnea. Among those with sleep apnea, about 65 percent required a C-section, while 33 percent of those without the condition required the surgery. Additionally, 42 percent of those with sleep apnea had preeclampsia, compared with 17 percent of those without sleep apnea. The rate of premature births was similar between the groups. The percentage of newborns requiring admission to the NICU was 46 percent for mothers with sleep apnea, compared with 18 percent for those without sleep apnea. Many of these admissions were due to breathing problems. The higher rate of NICU admissions for infants born to mothers with sleep apnea may be due to the higher rate of C-sections in this group, the researchers said. The best way to reduce the risks that come with obesity-related sleep apnea would be to treat obesity before a woman becomes pregnant, although losing weight is often difficult, the researchers said. Because the study only included obese women, it's not clear whether sleep apnea could have the same effects in women who are not obese. The study was published online Sept. 20 in the journal Obstetrics & Gynecology. 11 Big Fat Pregnancy Myths 5 Diets That Fight Diseases 9 Meal Schedules: When to Eat to Lose Weight
