- Mild obstructive sleep apnea (OSA) during pregnancy can affect fetal growth and fetal outcomes.
Why this matters
- OSA has been associated with obesity and morbidity.
- The prevalence of obesity and OSA is rising in pregnant women and is associated with gestational diabetes mellitus and hypertensive disorders of pregnancy.
- Large for gestational age (LGA) may predispose offspring to abnormal growth later in life.
- 17% had mild OSA.
- Mean BMI was higher in women with mild OSA.
- Mean birth weight percentile of infants was higher in women with mild OSA compared with control participants (72% vs 57%; P<.01>
- The proportion of LGA infants was higher in the mild OSA group (28% vs 8%; P=.04).
- The mean 1-minute Apgar score was lower in the mild OSA group (P<.01>
- Prospective cohort study of low-risk normal-weight pregnant women who were recruited between 25 and 27 weeks of gestation (n=155).
- Questionnaires were used to assess snoring before and during pregnancy.
- Participants had a sleep study between 33 and 36 weeks of gestation.
- Apgar scores and neonatal measurements were analyzed.
- Funding: Israel Science Foundation.
- An ambulatory sleep study was used as opposed to polysomnography.
- Lack of information on paternal BMI.
