“…In correlation analysis, both the number of night duties and weekly working hours emerged as significant determinants of sleep quality and daytime sleepiness. In the study by Mota et al 7 subjective sleep measures in resident doctors were investigated with dietary patterns and metabolic markers. They also used ESS and PSQI as subjective sleep measures, but in our study, we didn't investigate any metabolic markers.…”

Introduction: The aim of this study was to assess the sleep quality and daytime sleepiness of resident doctors, to compare the sleep quality between surgical and medical branch residents and to examine effects of working hours, number of duties, clinical branches and some other daily habits on the sleep quality of resident doctors in a hospital in Turkey. Methods: A survey was conducted to gather data on (i) demographics, lifestyle and daily habits as well as to determine (ii) Epworth sleepiness scale (ESS) score and (iii) Pittsburgh sleep quality index (PSQI) scores of the participants. Data collection was based on the use of a self-administered questionnaire. Results: Of 138 resident doctors, 45.7% were classified as having good sleep quality based on a cut-off score of 5 in PSQI. The mean ESS and PSQI scores were 6.59 ±3.92 and 6.30 ±3.22, respectively. Significantly positive correlations were found between Epworth score and the number of night duties (p=0.010), working hours per week (p=0.006), total cigarettes per day (p=0.033), and daily tea consumption (p=0.013). Also, there were statistically significant positive correlations between PSQI scores and the number of night duties (p<0.001), working hours per week (p=0.007), total cigarettes per day (p=0.013) and daily coffee consumption (p=0.002). Surgical residents had significantly poor sleep quality (p=0.015). ESS score was higher in female residents and surgical residents, with a significant difference in these two sub-groups (p=0.018, p=0.008 respectively). Conclusions: Sleep quality and daytime sleepiness of the resident doctors were closely related to lifestyle factors including working hours, number of night duties and branch of residency as well as to certain demographic factors and daily habits.

Study Objectives:We examined cross-sectional and prospective associations between sleep debt and adiposity measures, as well as homeostatic model assessment-insulin resistance (HOMA-IR) in early type 2 diabetes. Methods: Prospective data analysis from participants of a randomized controlled trial based on an intensive lifestyle intervention (usual care, diet, or diet and physical activity). Data were collected at baseline, 6 months, and 12 months post-intervention. The study was performed across five secondary care centers in the United Kingdom. Patients (n = 593) with a recent diagnosis of type 2 diabetes were recruited. Objective height and weight were ascertained for obesity status (body mass index [BMI]; ≥ 30 kg/m 2 ), waist circumference (cm) for central adiposity, and fasting blood samples drawn to examine insulin resistance (IR). Seven-day sleep diaries were used to calculate weekday sleep debt at baseline, calculated as average weekend sleep duration minus average weekday sleep duration. Results: At baseline, compared to those without weekday sleep debt, those with weekday sleep debt were 72% more likely to be obese (OR = 1.72 [95% CI:1.03-2.88]). At six months, weekday sleep debt was significantly associated with obesity and IR after adjustment, OR = 1.90 (95% CI:1.10-3.30), OR = 2.07 (95% CI:1.02-4.22), respectively. A further increase at 12 months was observed for sleep debt with obesity and IR: OR = 2.10 (95% CI:1.14-3.87), OR = 3.16 (95% CI:1.38-7.24), respectively. For every 30 minutes of weekday sleep debt, the risk of obesity and IR at 12 months increased by 18% and 41%, respectively. Conclusions: Sleep debt resulted in long-term metabolic disruption, which may promote the progression of type 2 diabetes in newly diagnosed patients. Sleep hygiene/education could be an important factor for future interventions to target early diabetes.

The impact of sleep debt on excess adiposity and insulin sensitivity in patients with early type 2 diabetes mellitus. J Clin Sleep Med 2016;12(5):673-680. I NTRO DUCTI O NThe International Diabetes Federation recently estimated that, globally, over 382 million individuals had diabetes in 2013 (an estimated 46.3% undiagnosed) and that this number is expected to rise to 592 million by 2035.1 The majority of affected individuals (over 90%) have type 2 diabetes, which is closely related to excess adiposity and its associated lifestyle factors such as poor diet and low physical activity. Sleep (duration and quality) may be another important factor associated with both obesity and type 2 diabetes, as suggested by both population and experimental studies.2-6 It has been hypothesized that social and work demands increasingly result in shorter sleep duration than required physiologically. 7 This sleep loss, accumulated into a sleep debt during weekdays, may be partially repaid by extra...

“…Shift work is common in medical professions and is necessary for 24-h hospital coverage. Shift work poses difficulties not only because of the loss of actual sleep hours, but also because it can affect other factors related to the lifestyle, such as food intake, physical activity level, and, therefore, metabolic patterns [13]. The causes of EDS are multifactorial, with possible risk factors previously identified as intrinsic sleep disorders, such as narcolepsy, obstructive sleep apnea; circadian rhythm disorders such as shift-work disorder; extrinsic sleep disorders such as poor sleep hygiene and insufficient sleep [14]; and other contributory lifestyle and health factors [15].…”

Objectives: Sleep disorders can affect health and occupational performance of physicians as well as outcomes in patients. The purpose of this study was to assess the prevalence of excessive daytime sleepiness (EDS) measured by the Epworth Sleepiness Scale (ESS) among academic physicians at a tertiary academic medical center in an urban area in the northwest region of Turkey, and to establish a relationship between the self-perceived sleepiness and the quality of life using the EuroQol-5 dimensions (EQ-5D). Material and Methods: A questionnaire prepared by the researchers after scanning the literature on the subject was e-mailed to the academic physicians of a tertiary academic medical center in Istanbul. The ESS and the EQ-5D were also included in the survey. The e-mail database of the institution directory was used to compile a list of active academic physicians who practiced clinical medicine. Paired and independent t tests were used for the data analysis at a significance level of p < 0.05. Results: Three hundred and ninety six academic physicians were e-mailed and a total of 252 subjects replied resulting in a 63.6% response rate. There were 84 (33.3%) female and 168 (66.7%) male academic physicians participating in the study. One hundred and eight out of 252 (42.8%) academic physicians were taking night calls (p < 0.001). Ninety study subjects (35.7%) felt they had enough sleep and 84 (33.3%) reported napping daily (p < 0.001). In our sample, 28.6% (N = 72) of the physicians felt sleepy during the day (ESS score > 10) (p < 0.001). In the case of the EQ-5D index and visual analogue scale of the EQ-5D questionnaire (EQ-5D VAS), the status of sleepiness of academic physicians was associated with a poorer quality of life (p < 0.001). Conclusions: More than a 1/4 of the academic physicians suffered from sleepiness. There was an association between the poor quality of life and daytime sleepiness. There was also a positive relationship between habitual napping and being sleepy during the day.
