Item type:Publication, Clinical Factors Associated with Very Severe Obstructive Sleep Apnea in Mongolian Patients: A Case-Control Study(Mongolian National University of Medical Sciences, 2021-09-21); ; Objectives: To determine risk factors and clinical characteristics of obstructive sleep apnea patients (OSA) according to the severity of the value of AHI ≥ 60 (Apnea-Hypopnea Index). Methods: A hospital-based, case-control study, December 2018 - 2020. Patients were grouped by severity of AHI as moderate, severe, and very severe. Results: Of 103 male cases, 52 were very severe obstructive sleep apnea (vsOSA). The control group consisted of 16 moderate OSA (mOSA) and 35 severe OSA (sOSA) patients. The case group consisted of 52 vsOSA patients. The average age was 48.7 ± 12.6. There was statistically significant increased body mass index (p < 0.003), systolic blood pressure, and abdominal circumference (p < 0.006) in the vsOSA group. Moreover, on polysomnography there was less deep sleep (p < 0.004), a greater arousal index (p < 0.000), higher apnea-hypopnea index (p < 0.000), and higher night systole pressure (p < 0.010). According to a bivariate analysis, abdominal circumferences were the variable with the closest association to the vsOSA group (crude OR: 9.14, p > 0.004), followed by decreased maximum saturation of O2 (crude OR: 6.6, p > 0.451). Conclusion: Of male OSA patients, 50.1% have vsOSA (AHI > 60) and most of them were obese and suffered from high blood pressure. Lower levels of O2 saturation and increased abdominal and neck circumferences were significant risk factors for the very severe obstructive sleep apnea group. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Obstructive Sleep Apnea in a Clinical Population: Prevalence, Predictive Factors, and Clinical Characteristics of Patients Referred to a Sleep Center in Mongolia(2021-11); ; ; Obstructive sleep apnea (OSA) disrupts sleep. This study examined factors related to OSA severity. A cross-sectional, prospective, hospital-based study was conducted with 205 patients who underwent polysomnography (PSG). Demographic, anthropometric, clinical, PSG, and sleep quality assessment data were analyzed. Participants (N = 205) were classified into four groups based on apnea-hypopnea index (AHI); no OSA (AHI < 5/h; N = 14), mild (mOSA, 5 < AHI < 15/h; N = 50), moderate (modOSA, 15 < AHI < 30/h; N = 41), severe (sOSA, 30 < AHI < 60/h; N = 50), and very severe (vsOSA, AHI ≥ 60; N = 50). Men had more severe OSA than women (p < 0.001). Anthropometric characteristics differed with OSA severity (p < 0.001). OSA patients had decreased sleep quality and increased excessive daytime sleepiness (EDS). Body mass index (BMI), neck/waist circumference, and blood pressure (BP) differed between groups (p < 0.001). Patients with vsOSA had the highest Mallampati grades (p < 0.001). Multiple linear regression indicated that OSA severity was related to gender and sleep quality. PSG parameters (oxygen saturation, systolic BP, and arousal/respiratory arousal) were strongly related to OSA severity. In conclusion, about half of study-referred patients had severe/very severe OSA; these groups were predominantly obese men with high BP. OSA severity associated with high BP, BMI, waist circumference, and neck circumference.Scopus© Citations 8
