Prevalence of obstructive sleep apnea in pregnancy: A hospital based study

Objective To assess the prevalence of obstructive sleep apnea among the hospitalized pregnant females at a tertiary care center. Methods A prospective, hospital-based study involving 1000 pregnant women in the age group of 18-45 years (mean 28.12+4.07 years). Diagnostic possibility of obstructive sleep apnea (OSA) was established on the basis of Berlin Questionnaire and Epworth Sleepiness Score. Random blood sugar estimation was done in every subject of the study group in addition to the baseline demographic profile. Results Major portion of the study group belonged to elderly age group (mean 28- 12+4.07 years). Body mass index was more in subjects having OSA as evidenced by the Berlin Questionnaire and Epworth Sleepiness score. Again arterial blood pressure (146.82+12.48mmHg) was more associated with subjects having OSA that was statistically highly significant (p < 0.001). Conclusion: A significant proportion (13.4%) of pregnant females in our study are at high risk for OSA. Keeping in view the importance of sleep disordered breathing in causing adverse maternal and fetal outcomes, as well as the mortality risk from anesthesia for cesarean section, we strongly recommend screening of all pregnant females for the presence of OSA so that treatment at the appropriate time period of pregnancy may improve the maternal and fetal outcome
