Methods: We enrolled 79 patients (aged 27–74 years) with chronic insomnia disorder (CID) who underwent overnight polysomnography (PSG) and completed sleep-related questionnaires as well as habitual sleep time. All of them completed actigraphy (ACT) recording for one week prior to the PSG study. Objective sleep duration for one-week average sleep was calculated by ACT, and subjective sleep duration was counted through self-reported habitual sleep time. We divided the subjects into three groups; OSSI (<6 h/night), SSSI (objective sleep ≥6 h/night and subjective sleep <6 h/ night), and normal sleep duration insomniacs (NSDI, subjective sleep ≥6 h/night). Results: The three groups namely OSSI, SSSI, and NSDI had 25 (31.6%), 36 (45.6%), and 18 (22.8%) subjects, respectively. The SSSI were significantly older and had higher daytime sleepiness than the OSSI. According to the PSG results, the OSSI showed shorter sleep latency (11.86 min vs. 39.69 min) and N2 sleep % (59.43% vs. 67.96%), and longer rapid eye movement sleep % (20.79% vs. 15.47%) than that in the NSDI. There was no difference in treatment response between groups. Conclusions: 45.6% of CID patients underestimated their sleep relative to objective sleep. However, there were no differences in total sleep time on PSG between groups. The OSSI showed younger age and more daytime sleepiness, and the SSSI showed poorer sleep quality than the NSDI. These findings suggest that long-term ACT recording in a casual environment would be useful to monitor objective sleep in patients with CID, particularly, in subjectively short sleep insomniacs.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85484275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We enrolled 344 nurses (mean age, 28.7 years) without prior history of sleep disturbance before starting shift work in a university-affiliated hospital. SSWD were defined using self-reported sleep questionnaires (insomnia severity index >14 and/or Epworth Sleepiness Scale ≥10) and without any sleep problem before shift work. Sleep pattern in each of the three shifts was measured using the Munich Chronotype Questionnaire for Shift-Workers. Mood (anxiety, depression) and job stress were also measured using self-reported questionnaires. Results: Our results showed that 62.2% of the participants presented SSWD. Compared to the non-SWD group, the SSWD group showed worse sleep hygiene, lower total sleep time (TST) during workdays, higher anxiety and depressive mood, and higher job stress. In the SSWD group, the evening chronotype individuals presented the shortest TST during day shifts, while the morning chronotype individuals presented the shortest TST during evening shifts. Conclusions: SSWD is highly prevalent in fast rotating three-shift nurses. This study suggests that intensive education on sleep hygiene and appropriate scheduling of shift work while considering individual chronotypes may improve sleep patterns and sleep quality of shift workers and minimize SSWD.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77938182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She showed severe hypercapnia without definite lung disease and hypoxic injury on brain image. After the acute period, she still had excessive daytime sleepiness, and the hypercapnia aggravated during the night. Polysomnography revealed severe obstructive sleep apnea, a sleep-related breathing disorder with a high apneahypopnea index of 60.2/h (mainly a hypopnea index of 59.0/h). She was diagnosed with combined obesity hypoventilation syndrome (OHS) and sleep-related breathing disorder, as the cause of daytime hypercapnia and excessive daytime sleepiness. Three months of successful bi-level positive airway pressure (BiPAP) therapy dramatically improved her daytime sleepiness and cognition. This case suggests that patients with OHS can be susceptible to hypoxic brain damage, and emphasizes the importance of the recognition and diagnosis of OHS and appropriate treatment with BiPAP therapy.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89755716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and methods: An exploratory study was conducted in New Delhi among 100 young adults aged 20–40 years in the year 2018, using a convenience sampling method. Body composition was assessed using Tanita UM-075. The relationship between the variables was measured with Spearman correlation analysis. Multivariable logistic regression analysis was conducted to determine the predictors for poor sleep quality. The receiver operating characteristics (ROC) curve was used to determine the predictive accuracy of the model. Results: Among all, 57% had sound quality sleep followed by 43% with disturbed; 23% were highly stressed, 71% moderately, and 6% low stressed. Significant correlation between sleep quality and risk factors for NCDs like body mass index (BMI) ( r = 0.8111, p < 0.001), waist circumference ( r = 0.6661, p < 0.001), body fat percentage ( r = 0.3692, p = 0.002), visceral fat ( r = 0.68, p < 0.001), stress score ( r = 0.092, p = 0.36), muscle mass (MM) ( r = 0.36, p = 0.0002). High BMI was observed to be an independent predictor for disturbed sleep quality (odds ratio 4.31, 95% CI 1.98–9.38). The area under the curve for the prediction of sleep quality was observed 0.97% using a combination of BMI, MM, duration of sleep. Conclusion: High BMI was observed to be an independent predictor (4.31 times higher) for the disturbed sleep quality. Clinical significance: Lifestyle modifiable factors should be looked upon when dealing with patients with disturbed sleep quality.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45451404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The secondary aim was to find whether the total calorie intake and the sleep quality of the subjects had any relation. Materials and methods: Students were divided into four groups according to gender and whether they are vegetarians or non-vegetarians. All of them were required to fill their daily food consumption questionnaire, at the end of each day, for 28 days. At the end of this period, they had to fill the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The total calorie intake and PSQI scores were calculated and analyzed. Results: The average calorie intake and PSQI score of non-vegetarians are ± SD = 50747.78 ± 15068.05 kcal and 5.76 ± 2.57, respectively. The average calorie intake and PSQI score of vegetarians are ± SD = 60342.63 ± 18309.56 kcal and 6.02 ± 2.66, respectively. No significant correlation was found to exist between calorie intake and sleep quality, in any of the individual groups nor overall. Conclusion: The average calorie intake of vegetarians was higher, but their sleep quality was worse, due to more carbohydrate consumption and less protein consumption as compared to the non-vegetarians. More of carbohydrate and less of protein had resulted into their poorer sleep quality. Boys had overall better sleep quality than girls. Excess intake of snacks and fast food and consuming less variety of foods, as mostly seen in girls, were also found to be the dietary reasons behind their poorer sleep quality. Clinical significance: This study will help hostellers in finding the balanced combination of food components that are best for them to lead a healthy life and get the very needed sound sleep and can be beneficial for different institutions in designing their balanced hostel mess menu.","PeriodicalId":90527,"journal":{"name":"Indian journal of sleep medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42631324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
