Taiwan: A recent meta-analysis, published in JAMA Network Open, suggests that continuous positive airway pressure (CPAP) treatment for pregnant women with obstructive sleep apnea (OSA) could potentially lower the risk of adverse gestational hypertensive outcomes.

"In the systematic review and meta-analysis of six studies involving 809 pregnant women with OSA, the combined results revealed a significant reduction in the risk of gestational hypertension by 35% and preeclampsia by 30%," the researchers reported.

Pregnancy can either trigger or worsen obstructive sleep apnea and elevate the risk of gestational complications. Continuous positive airway pressure is the primary and standard treatment for OSA and is considered the most practical option during pregnancy. However, the relationship between CPAP therapy and the reduction of gestational complications in pregnant women with OSA remains uncertain. To fill this knowledge gap, Yi-Chieh Lee, New Taipei Municipal Tucheng Hospital, New Taipei City, Taiwan, aimed to investigate the association between CPAP therapy in pregnant women with OSA and the reduction of adverse hypertensive outcomes during gestation.

Keyword searches were conducted across PubMed, Embase, and the Cochrane Database of Systematic Reviews and Clinical Trials from inception to November 5, 2023. Studies were selected based on their reporting of the impact of CPAP use on reducing the risks of hypertension and preeclampsia in pregnant women with obstructive sleep apnea (OSA).

Two authors independently extracted data following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Meta-analyses using a random-effects model were performed, and risk ratios (RRs) were reported. The analysis also included subgroup assessments, meta-regression based on age and body mass index (BMI), and evaluation of publication bias.

The primary outcome measured was the risk ratio of gestational hypertension and preeclampsia between pregnant women with OSA who received CPAP treatment and those who did not.

The researchers reported the following findings:

  • Six original studies with 809 participants (mean age, 31.4 years; mean BMI, 34.0) were identified and systematically reviewed for meta-analysis.
  • The pooled results showed significant differences between the intervention (CPAP use) and the control (non-CPAP use) groups in reducing the risk of gestational hypertension (RR, 0.65) and preeclampsia (RR, 0.70).
  • Meta-regression revealed that patients’ age (coefficient, −0.0190) and BMI (coefficient, −0.0042) were not correlated with a reduction of risk of hypertension and preeclampsia.

The findings suggest that pregnant women may develop or have worsened obstructive sleep apnea, potentially increasing the risk of gestational complications.

"The meta-analysis found that CPAP treatment significantly reduced the risk of gestational hypertension and preeclampsia in pregnant women with OSA. Future research should focus on evaluating treatment adherence and determining the optimal timing and duration for CPAP use," the researchers concluded.
