We have looked at the difference between tiredness on the STOPBANG Questionnaire and sleepiness on the self-completed Epworth Sleepiness Score (ESS) to identify if there is a subjective difference and how this relates to sleep physiology.Methods: Patients referred for bariatric surgery who had an ESS, a STOPBANG Questionnaire assessment and a sleep study were assessed. Comparisons were made between the “tired” and “sleepy” groups.Results: Out of the 113 patients, 73 were tired and 40 were not tired. 27 patients were sleepy and 75 were not sleepy. As anticipated, there is a strong relationship between tiredness and sleepiness (p=0.01). However neither tiredness nor sleepiness related to physiological parameters of nocturnal desaturation and Apnoea Hypopnea Index(AHI).Tired (n=73)Not-tired (n=40)p valueMeanSDMeanSDESS8.735.16.034.5540.01BMI45.328.2146.138.2630.62ODI>4%26.3823.4025.0923.810.538Desaturation<90%10.3616.5211.4117.650.961Desaturation<85%1.94.794.1510.810.325AHI23.8523.4427.8725.410.951SD - Standard DeviationComparison between the tired and non-tired groupESS 11 (n=27)ESS<11 (n=75)p valueMeanSDMeanSDBMI45.158.2145.668.3320.524ODI>4%28.8225.6925.3423.640.652Desaturation<90%14.3720.789.9515.810.226Desaturation<85%3.546.662.708.300.206AHI30.0127.5426.923.680.990Comparison between the sleepy and non-sleepy groupConclusion: 1) There is a strong relationship between tiredness and sleepiness in this obese population.2) There was no relationship between self-reported sleepiness or tiredness to the severity of sleep disordered breathing.
