Factors Affecting Severity of Obstructive Sleep Apnea
Keywords:
Obstructive sleep apnea, Polysomnography, Risk factors, SeverityAbstract
Obstructive sleep apnea (OSA) may contribute to several health problems and complications. There have been limited numbers of devices available for facilitating the diagnosis. Thus, major risk factors associated with OSA can be used as a screening tool to identify people who are at risk of OSA. This will help in early diagnosis and appropriate treatment of OSA.
Objective: To explore risk factors for the severity of OSA
Methods: This study was a retrospective cohort study of patients with OSA confirmed by using polysomnography between September 2017 and August 2019 at the outpatient OSA clinic, Chaiyaphum hospital. Patients were divided into two groups, including mild and moderate-to-severe groups. The patient characteristics between the two groups were compared.
Results: Of the 468 patients who were included in the study, the majority of patients was males (67%) and had moderate-to-severe OSA (70%). The significant risk factors of moderate to severe OSA included male gender, body mass index ≥ 25 kg/m2, neck circumference ≥ 35 cm, systolic blood pressure ≥ 140 mmHg, hypertension, diabetes mellitus and enlarged uvula. Nevertheless, multivariable logistic regression showed that only neck circumference ≥ 35 cm, hypertension and enlarged uvula were significantly different between the two groups.
Conclusion: Identification of different risk factors of moderate-to-severe OSA in clinical settings may help otolaryngologists and general physicians to prioritize the need for further diagnosis and to provide appropriate treatment for patients.
