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

- 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.
