Impact of common diseases and habits on daytime sleepiness in adults

Abstract

We aimed to investigate the impact of common diseases and habits on daytime sleepiness in adults. We retrospectively collected the clinical and overnight polysomnographic data of 2829 adults. The impact of common diseases and habits on the Epworth Sleepiness Scale (ESS) score was analyzed by univariate and multivariate linear regression analyses. The mean ESS score was 6.2 (standard deviation = 4.3; range = 0-24) for all adults. Multivariate linear regression analysis showed that dyslipidemia, acute myocardial infarction (AMI), liver cirrhosis, alcohol drinking, and tea consumption had a significantly positive association with ESS score for all adults after adjusting for age, sex, body mass index, apnea-hypopnea index, sleep efficiency, percentage of sleep N3 stage, and depression. Subgroup analysis by sex showed that AMI, liver cirrhosis, alcohol drinking, and tea consumption had significantly positive association with ESS scores in males, whereas only dyslipidemia had significantly positive association with ESS scores in females. Subgroup analysis by age showed that alcohol drinking had a significantly positive association with ESS scores in young adults. AMI had a significantly positive association with ESS scores, but chronic kidney disease had a significantly negative association with ESS scores in middle-aged adults. Furthermore, dyslipidemia, chronic kidney disease, and cancers had a significantly positive association with ESS scores in older adults. Dyslipidemia, AMI, liver cirrhosis, alcohol drinking, and tea consumption had a significantly positive association with daytime sleepiness in adults but differed by sex and age.
