Excessive daytime sleepiness in late pregnancy may not always be normal: results from a cross-sectional study

Abstract Background Sarcopenia is emerging as an important public health problem, and evidences have determined that poor sleep is associated with muscle strength, but the potential effects of excessive daytime sleepiness (EDS), snoring and witnessed apnea on handgrip strength have not been evaluated. Aim We aimed to examine the association between EDS, snoring, witnessed apnea and muscle strength in an adult population. Design Cross-sectional study. Methods This cross-sectional study comprised 19 434 adults. Handgrip strength was measured using a handheld digital dynamometer. EDS was assessed by Epworth Sleepiness Scale, snoring and witnessed apnea during sleep were reported through simple yes/no questions. Analysis of covariance was carried out to determine the association between EDS with snoring or witnessed apnea and muscle strength. Results The means (95% confidence interval) for average handgrip strength/body weight (kg/kg) across symptoms categories were 0.396 (0.333–0.472), 0.393 (0.330–0.467), 0.396 (0.333–0.471) and 0.386 (0.325–0.460) (P < 0.0001), respectively. Similar results were observed with maximal handgrip strength/body weight (kg/kg). Conclusions Self-reported EDS accompanied with snoring or apnea is associated with lowest handgrip strength, independently of confounding factors. Whether improvement of EDS, snoring and apnea, can ameliorate age-associated decline in muscle strength warrants further studies.

Introduction: Excessive Daytime Sleepiness is a significant health problem among medical students worldwide which can impair their cognitive and academic performances. Our study aims to determine the prevalence of Excessive Daytime Sleepiness among the first to fourth year undergraduate students of the Nepalese Army Institute of Health Sciences-College of Medicine. Methods: Following the ethical approval from the Institutional Review Committee with registration no. 317, a descriptive cross-sectional study was conducted among the first to fourth year medical students of the Nepalese Army Institute of Health Sciences-College of Medicine from 4" to 10" August 2020. Two hundred and thirty-two students were selected for the study using the stratified random sampling technique. Epworth Sleepiness Scale was used to obtain data on daytime sleepiness among the study participants. The data were entered into Google spreadsheets and later analyzed. Point estimate at 95% Confidence Interval was calculated along with the frequency and proportion for binary data. Results: The prevalence of Excessive Daytime Sleepiness among the first to fourth year undergraduate students of the Nepalese Army Institute of Health Sciences-College of Medicine is found to be 67 (31.02%) at 95% Confidence Interval (24.85-37.19). It was found to be highly prevalent among the fourth year undergraduate medical students 20 (35.09%) and least prevalent among the first year students 13 (26.00%). Excessive Daytime Sleepiness was found to be slightly higher among females 23 (34.85%) than males 44 (29.33%). Conclusions: Excessive Daytime Sleepinessis highly prevalent among medical students in our study as suggested by various international studies.

Obstructive Sleep

Background: Obstructive sleep apnea (OSA) is a condition resulting in disrupted sleep and excessive daytime sleepiness/somnolence (EDS) with demonstrable deficits in cognitive and psychomotor performance. Indian studies have shown the prevalence of 4.9–19.7% in males and 2.1–7.4% in females. Prevalence among military aviators is unknown. Materials and Methods: EDS was determined by employing Epworth Sleepiness Scale (ESS) among the 54 male aircrews in an airbase. The risk for OSA was also determined among these individuals using STOP-BANG questionnaire. Results and Discussion: It was found that none of the aircrews in the study group is found to have dangerously sleepy (DS). About 11.11% of the studied population were found to have EDS which is less than the prevalence rate in India as per a study conducted by the National Institute of Mental Health and Neuro Sciences on general population and the Western world (prevalence rate of 16.7%) as found by Gislason et al. OSA risk among the study population was (n = 9/54) 16.16%. The prevalence of OSA in India male is reported as 4.9–17.9%. Thus, percentage of aircrew showing the risk for OSA in this cross-sectional study is comparable with the general population in India. However, no correlation was found between the risk factors of OSA with ESS. The reasons for EDS could be attributed to factors such as personal lifestyle, sleeping habits, and poor work-rest schedules. It is interesting to note that none of the aircrew, who is positive for OSA risk, is showing EDS/DS. This further confirms that OSA risk individuals may not have EDS/DS and this could be a reason why, OSA largely remains underdiagnosed and untreated in clinical practice. Conclusion: This cross-sectional study has brought the conclusion that both EDS and risk for OSA coexists even in a fit and healthy population of aircrew.
