Our aim was to estimate the prevalence of reported preeclampsia / hypertension among women who were later diagnosed with OSA.Material and methods The OSA women (n=156) newly diagnosed with moderate or severe OSA mean (SD) AHI 42.6 (20, 0), mean ODI 32, 0 (20,0). They all answered a questionnaire including questions about sleep, symptoms of OSA and if they had been diagnosed with preeclampsia (PE) or pregnancy induced hypertension (HT).Results Among the 156 OSA women 146 had been pregnant and 31% reported that they had during pregnancy been diagnosed with PE and 37% HT. When the OSA women reporting preeclampsia were compared to OSA women not reporting PE, they were more likely to be more obese BMI 35,6 m², (6,3) vs. 32,5 m², (5,3), p=0,002), younger (mean age 56,1 vs. 59.6 years, p=0,01), and current smokers (29% vs. 13%). In a multivariate logistic regression, they are also more likely to report nocturnal sweating and morning headaches after adjusting for significant demographic factors. No significant differences were found in OSA severity, insomnia, cardiovascular diseases, diabetes, obstructive lung diseases, restless legs syndrome between OSA women reporting PE and those who did not.Conclusion Among women OSA patients one third reported having had preeclampsia or hypertension during pregnancy which is three times more often than reported in the general population. These women were compared to other OSA women more obese, younger, more often smokers and reporteted night time sweatening and headache upon wakening more often. ER -
