Snoring, sleepiness and sleep disordered breathing during pregnancy
2015 (English)Manuscript (preprint) (Other academic)
Study objectives: To investigate if sleep recordings show differences in prevalence of sleep-disturbed breathing among pregnant women compared to non-pregnant controls. To compare the Epworth sleepiness scale (ESS) scores between the two groups. To evaluate obstetric outcomes.
Setting: At one antenatal care center at an outpatient unit in Linköping, Sweden.
Participants: One hundred pregnant women (gestational week 24-34) and 80 non-pregnant women age- and body mass index-matched as controls.
Interventions: Whole-night respiratory recordings were performed in the homes of all participants, who also answered the same questionnaire, including the Epworth Sleepiness Scale.
Measurements and results: Objectively recorded snoring was more common among the pregnant women (median value 10% of total estimated sleep time) than among the non-pregnant controls (2.5% of total sleep time, p<0.001). The prevalence of obstructive events was low and similar in pregnant and non-pregnant women (1% vs. 3% had obstructive apnea-hypopnea index ≥5). The total ESS score was higher among pregnant women than controls (median 9 vs. 7, p<0.001) but no significant differences were found between the two groups in the scores for the separate items of the ESS. Sleep-disturbed breathing and snoring showed no impact on obstetric outcome. There were no significant associations between either subjectively reported or objectively recorded snoring and ESS scores.
Conclusion: Snoring increases during pregnancy, but sleep recordings could not verify an increased prevalence of obstructive sleep apnea among pregnant women. Development of obstructive sleep apnea is not a likely explanation for the increased daytime sleepiness seen in pregnant women.
