title: [Clinical characteristics of sleep apnea-hypopnea syndrome in women].
abstract: OBJECTIVE
  To realize the characteristics of symptoms and polysomnography in women with sleep apnea-hypopnea syndrome (SAHS) compared with that of male patients.
  
  
  METHODS
  The symptoms and polysomnography were compared between men and women with SAHS and among mild (5 to 19 events/h), moderate (20 to 39 events/h), severe (> or = 40 events/h) of female patients.
  
  
  RESULTS
  Female patients were older than that of male(51.1 +/- 11.2 yr versus 43.9 +/- 10.1 yr). The mean body mass index(BMI) for women was (27.8 +/- 3.9) kg/m2 and (28.1 +/- 3.8) kg/m2 for men. Women with higher AHI snored more severely, and female had a lower apnea hypopnea index (AHI) and apnea index (AI) but higher hypopnea index (HI) than did male. In addition, the respiratory events during non-rapid eye movement for men were significantly higher than that for women.
  
  
  CONCLUSIONS
  Female patients are older than male but not more adipose. SAHS and respiratory events during NREM sleep are less severe in women.
