Screening for Obstructive Sleep Apnea Among the Adult Population in the Northeastern Region of Romania.

: Sleep apnea is a breathing affliction that affects sleep quality, with significant implications for overall physical and oral health, as well as mental health. : The aim of this study was to evaluate the validity of the STOP-Bang and Epworth questionnaires as preoperative screening tools for obstructive sleep apnea (OSA) in the adult population from the NE region of Romania. : A total of 222 participants were selected. The questionnaire method was used, with the subjects completing the STOP-Bang and Epworth questionnaires. A chi-squared test, an ANOVA, and Student's -tests were used for the statistical analysis. : the STOP-Bang questionnaire revealed an increased risk of OSA among those with a high BMI, an age over 50 years, or a large neck circumference. Regarding the Epworth questionnaire, daytime sleepiness was more frequent among obese individuals and those with associated pathologies. Significant correlations were found between OSA and obesity, age, and associated pathologies, with limited observations on the influence of gender on the risk of OSA. : The studied questionnaires are effective and easy-to-use tools for the preoperative screening of OSA, demonstrating a significant correlation between the identified risk factors and the disease severity.
