title: Obstructive sleep apnea hypopnea syndrome was a risk factor for uncontrolled hypertension in adult snorers in South China.
abstract: BACKGROUND
  The association of obstructive sleep apnea hypopnea syndrome (OSAHS) with uncontrolled hypertension has not been fully investigated to date. The present article will investigate the associated factors of uncontrolled hypertension in South China Method: A total of 668 patients (531 males, 137 females) in South China were enrolled in this study. All patients completed questionnaires and then underwent an in-hospital polysomnography.
  
  
  RESULTS
  Univariate analysis showed that drinking, apnea-hypopnea index, Epworth Sleepiness Scale (ESS) index, the presence of OSAHS, MSaO2 and the lowest SaO2, circumference of neck and waist were predictors of uncontrolled hypertension. Multiple logistic regression analysis showed that ESS, presence of OSAHS, and the lowest SaO2 was independently associated with the risk for uncontrolled hypertension.
  
  
  CONCLUSIONS
  The lowest SaO2, ESS index, and OSAHS were risk factors for uncontrolled hypertension.
