Abstract

Obstructive sleep apnea (OSA) is linked with important clinical, cardiometabolic, anthropometric, and upper-airway abnormalities. Early identification of adults at high risk may support timely clinical evaluation and referral. This secondary observational analytical study included 343 adults classified as having high or low OSA risk. Demographic, clinical, behavioral, cardiometabolic, anthropometric, sleep-related, and upper-airway characteristics were evaluated. Continuous variables were analyzed with the independent-samples t-test, categorical associations were investigated using the chi-square test, and the relationships among continuous variables were assessed using Pearson correlation, and logistic regression was used to find factors linked to high OSA risk. 44.31% of subjects had a high OSA risk. High-risk individuals showed greater daytime sleepiness, body weight, BMI, neck circumference, and abdominal circumference. Snoring, sleepiness category, BMI category, hypertension, smoking, and marital status were significantly associated with OSA risk. Significant upper-airway associations were observed for palatopharyngeal insertion, Friedman tongue position, tongue abnormality, and palatopharyngeal gap. Strong positive correlations were found among obesity-related anthropometric measures. Logistic regression further identified snoring, obesity, high daytime sleepiness, hypertension, smoking, increased anthropometric measures, and selected upper-airway characteristics as significant individual factors related with high OSA risk. High OSA risk was closely related to symptomatic, cardiometabolic, anthropometric, and selected upper-airway characteristics. Combining routine clinical assessment with anthropometric and upper-airway evaluation may improve early identification of adults requiring further diagnostic assessment.
