Teklu M, Gouveia CJ, Yalamanchili A, et al. - Researchers conducted this cross-sectional study to illustrate the prevalence of otolaryngologic symptoms among individuals being assessed for obstructive sleep apnea (OSA). Given the results that the Reflux Symptom Index (RSI) was strongly correlated with OSA status, they assessed the RSI's diagnostic usefulness in predicting OSA status. From July 2017 to July 2018, 101 adults presenting for ambulatory polysomnograms to the Northwestern Sleep Disorders Center were selected. Upon univariate regression, age, BMI, and RSI were linked to OSA status. OSA patients have worse laryngopharyngeal reflux symptoms, as assessed by RSI. Adding the RSI to recognized age and BMI factors improve OSA's diagnostic utility.
