“…It has been shown that troubled or fragmented sleep patterns are hallmarks of mood disorders, especially depression [14]. At least 80% of depressed people experience insomnia-difficulty falling asleep or most often, staying asleep [15] [16]. Early morning awakenings are a very characteristic feature of depression and they may also have problems associated with poor sleep quality like day time sleepiness, headache, apnoeic spells, obesity and predispositions to a variety of other morbid illnesses of which the most important remain hypertension and diabetes [15] [16].…”

The aim of this study is to investigate the possible risk factors of poor sleep quality among patients with type 2 diabetes mellitus on insulin therapy. The factors considered were age, sex, body mass index (BMI), glycosylated haemoglobin (HbA1c), duration of diabetes and depression. A total of 202 diabetic patients aged 20 years or older were included in the study. The results showed that female sex and depression were independent risk factors for poor sleep quality among type 2 diabetics on insulin therapy. Findings may contribute to sleep disorder control in female patients with type 2 diabetes mellitus which has been linked to glycemic control. A. Sathyanarayanan et al. 207 activity are designed to prevent and manage diabetes and its complications. New strategies against the disease are needed. This is vital for the development of more efficient methods to counteract the progress of the disease and channelize our efforts directed at changes which most affect the disease. One component which is shown to have an impact is the relationship between diabetes and sleep quality [2]. Studies in other parts of the country have reported that short sleep duration or poor sleep quality may relate to glucose metabolism. Insulin administration was reported to be an important reason for the prevalence of sleep abnormalities. Data suggest that diabetes is associated with periodic breathing, a respiratory abnormality associated with abnormalities in the central control of ventilation, which in turn affects sleep [3].This can have many ramifications over the course and treatment of the patients who are on chronic insulin therapy. Not many studies have examined the factors associated with poor sleep quality in patients with type 2 diabetes using insulin. A recent study was conducted including 140 type 2 diabetics on insulin therapy. The possible risk factors that were considered in the study were age, sex, BMI, HbA1c, duration of diabetes and global PSQI score [4]. The results of the study showed poor sleep quality in females type 2 diabetes patients with insulin therapy. However, in this study depression was not considered which might confound the findings. In addition, many studies have reported a higher prevalence of depression among patients on insulin therapy [5]- [7]. The aim of the present study is to examine the factors associated with poor sleep quality among type 2 diabetes on insulin therapy. The factors considered were age, sex, BMI, HbA1c, duration of diabetes and depression.

“…This relationship may occur because snoring is caused by increased airway resistance, which is one of the typical symptoms of obstructive sleep apnea, which induces masticatory muscle activity that in turn may trigger bruxism. 35 Carra et al 21 also reported that children with bruxism complain about sleep disorders; however, they did not find any connection between nightmares, snoring and bruxism. In the present study, children who snore and have nightmares were more likely to gnash their teeth compared to those without this habit.…”

“…Other studies [16][17][18]35 found an association between snoring and bruxism. This relationship may occur because snoring is caused by increased airway resistance, which is one of the typical symptoms of obstructive sleep apnea, which induces masticatory muscle activity that in turn may trigger bruxism.…”

“…Questions on daily-life habits included school-commute time, time spent engaging in school sports (or clubs), time spent on study outside school hours, television-viewing time, and skipped meals. These questions were similar to those used in previous studies among adolescents [10,[31][32][33] (Appendix A). The questions on emotions and perceptions were measured by depressed mood (mental health) and school-life satisfaction.…”

Background: Worldwide, the increase in the number of Internet users has increased Internet dependence. In adolescents, this dependence interferes with sleep, which is important for the development of psychophysiological capabilities. However, few large-scale surveys have descriptively examined the relationship between Internet addiction (IA) and sleep disturbance using standardized questionnaires. We conducted this study to determine the relationship between sleep disturbance in adolescents and IA based on the categories of the Young Diagnostic Questionnaire (YDQ) through a complete survey of one prefecture in Japan.Methods: In 2016, a self-report questionnaire was used to survey high school students (n=10,405, age range: 15-16 years) in all 54 day-boarding high schools in the selected prefecture. We defined "sleep disturbance" by scores greater than 5.5 points on the Japanese version of the Pittsburgh Sleep Quality Index. IA was evaluated using the YDQ: "IA," when 5 of the 8 YDQ items were present; "at-risk," when either 3 or 4 YDQ items were reported; and "non-IA," when less than 2 YDQ items were positive.Multiple logistic regression analysis was undertaken with sleep disturbance as the dependent variable, IA as the explanatory variable, and adjustments for 8 items.Results: High YDQ scores were associated with high prevalence rates of sleep disturbance in both male and female participants. These findings persisted after controlling for other factors in the multiple regression model. Conclusions: Among Japanese adolescents, there exists a significant independent relationship between IA and sleep disturbances.
