Obstructive sleep apnea (OSA) disrupts normal sleep patterns and has wide-ranging effects on overall health, including physical, oral, and mental well-being. This study aimed to determine whether the STOP-Bang and Epworth Sleepiness Scale questionnaires can reliably identify adults at risk for OSA in the northeastern region of Romania prior to surgery. A cohort of 222 adults completed both the STOP-Bang and Epworth questionnaires. Responses were analyzed using chi-squared tests, ANOVA, and Student’s t-tests to examine associations between risk factors and OSA indicators. Participants with elevated BMI, age exceeding 50 years, or increased neck circumference were more likely to be flagged as high-risk by the STOP-Bang questionnaire. The Epworth questionnaire indicated that daytime sleepiness occurred more frequently among those with obesity or existing medical conditions. Strong links were observed between OSA and age, obesity, and comorbidities, while gender showed a limited impact on risk. The findings suggest that both the STOP-Bang and Epworth questionnaires are practical and efficient tools for preoperative OSA screening. Their results correlate closely with established risk factors and may help identify patients at higher risk of sleep apnea-related complications.
