Sleep Apnea, Obesity and Pregnancy (GOS)

June 2, 2015 updated by: University Hospital, Rouen

Main objective:

Determine the prevalence of obstructive sleep apnea syndrome (OSA) in late pregnancy in a population of obese patients .

Secondary objectives :

  • Identify risk factors for OSA during pregnancy (age, parity, high blood pressure, snoring , weight, neck circumference, scores on symptoms of sleep apnea, ... ) .
  • Compare perinatal morbidity among obese patients with OSA in late pregnancy with case-controls.
  • Evaluate the evolution of a moderate or severe OSA 6 months after pregnancy.

Material and methods

Characteristics of the study:

  • Interventional biomedical research
  • Prospective Multicenter nonrandomized study

Flow chart

  • Patients will be included between 30 and 36 weeks of amenorrhea (WA) .
  • Will rated from inclusion: age, parity, weight, height, BMI in early pregnancy, neck circumferrence, treated high blood pressure.
  • As recommended in France, the main test results during the pregnancy follow-up will be recorded.
  • At the inclusion visit will be conducted a Berlin Questionnaire and Epworth Score.
  • Screening for OSA by nocturnal polysomnography will be performed between 30 and 36WA. This screening can be performed as an outpatient.
  • In case of proven OSA patients will be offered an appropriate care by today's standards.
  • Whatever the outcome of pregnancy, a second polysomnography will be performed 6 months after childbirth in case of OSA during pregnancy.
