Prevalence, Risk Factors and Clinical Manifestation of Patients Suspected as having Obstructive Sleep Apnea in Songklanagarind Hospital Sleep Center
Abstract
Objective: To identify the prevalence and to determine both risk factors and clinical manifestation of obstructive sleep apnea (OSA). Material and Methods: A retrospective study was conducted to review the medical records and polysomnographic data of patients from March 2006 to December 2017. Results: A total of 929 patients was enrolled, however, only 124 patients had habitual snoring (13.4%). The prevalence of OSA and OSAS was 85.6% and 52.7% respectively. OSA was more prevalent in men than women (60.5% vs 25.1%). The presence of HT or symptoms of choking, gasping and neurocognitive impairment were significantly greater in OSA patients compared with the non-OSA group. In multivariate analysis, it was revealed that male gender, age ≥50 years, body-mass index (BMI) >25 kg/m2, neck circumference (NC) >40 cm and waist to height ratio (WHtR) >0.6 were the significant predictors for OSA. Conclusion: This study demonstrated that; OSA is a major health concern within the Thai population. Male gender, elderly age and those higher in BMI, NC or WHtR can be predicted as having the presence of OSA.
