The purpose of this study was to examine the relationship between hours of sleep and periodontal diseases among adolescents based on the raw materials of the 5th third-year(2012) national health and nutrition examination survey. The subjects in this study were 593 selected teens who were at the western ages of 12 to 18. SPSS 18.0 for Windows was used to analyze general characteristics, health behavior, oral health care, mental health, and relationship of sleep duration to periodontal disease. As a result, the groups of adolescents who were older and whose household income was larger slept for less hours, and higher toothbrushing frequencies led to more hours of sleep. There were 2.28-fold more periodontal diseases in the group that got five or less hours of sleep than in the group that got eight or more hours of sleep. The above-mentioned findings of the study illustrated that insufficient sleep is linked to periodontal health in adolescence.

Background: The current pandemic has affected people's health multidimensionally. This study aims to investigate musculoskeletal pain, sleep quality, depression levels, and their relationships in individuals belonging to different age groups during COVID-19 in Turkey. Methods: A web-based self-administered survey that consisted of demographic questions, The Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and scores of musculoskeletal pain was sent to participants. Pearson correlation analysis was used for determining the statistical relationship between variables. Results: The study includes 1,778 participants. The highest percentage for mild, moderate, and severe pain was in the head (49.8%), back (15.5%), and head (11.5%), respectively. The PSQI-total had shown a weak correlation with pain levels in all body parts. The highest correlation for sleep quality and pain levels was between the PSQI-5 and lower back pain. There was a weak correlation between PSQI-2 and the BDI score, and a moderate correlation between the PSQI-1, PSQI-5, PSQI-7, PSQI-total, and BDI score. Pain in all body parts showed a weak correlation with depression level. Conclusions: This study showed that musculoskeletal pain was varied in body parts with different intensities according to age groups in Turkey during the pandemic. The most common pain was in the head, back, and lower back. Headache was found correlated with the parameters of sleep quality. Pain of the head, neck, back, lower back, and shoulder were correlated with sleep latency. Sleep quality was associated with depression and musculoskeletal pain, while musculoskeletal pain was correlated with depression.

Objective : Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) is known to reduce the quality of sleep and is associated with various psychiatric disorders. The aim of this study was to investigate the relationship of PMS with depression, sleep qulity and sleep pattern in Korean female adolescents. Methods : Out of 867 high school female students, 400 female subjects were included in this study. All participants completed self-report questionnaires that included demographic variables, shortened premenstrual assessment form (SPAF), patient health questionnaire-9 (PHQ-9), Pittsburgh sleep quality index (PSQI), Epworth sleepiness scale (ESS), insomnia severity index (ISI) and Korean translation of composite scale (CS). A total of 394 individuals who completed the questionnaires were analyzed. Results : As score of SPAF, 143 subjects was defined PMDD group. They had more prevalence of eveningness, more depressive symptom, poorer sleep quality, and more excessive sleepiness than non-PMDD groups. Although the PMDD groups showed more menstrual dysmenorrhea, no difference was found in bleeding duration and cycle. PMS symptom had correlations with depression, poorer sleep quality and excessive sleepiness during the daytime. There was no difference in sleep duration between two groups, but PMS might have a relationship with eveningness of chronotype. Conclusions : Among Korean female high school students, the PMS might have an association with depression and poor sleep quality, and it might lead to daytime impairment due to excessive sleepiness. An appropriate evaluation of PMS could be helpful in determining the mental health condition of adolescents.

This study was conducted to determine the association between quality of sleep (QOL) and the general characteristics, the health-behavioral factors, and the occupational characteristics of firefighting officers. The survey was conducted in October 2016 with a self-administered questionnaire using the Pittsburgh Sleep Quality Index (PSQI) developed by Pittsburgh University, targeting 600 male firefighting officers working at five fire stations in D city. As a result, the QOL of the study subjects measured by the PSQI revealed 13.2% to be good, and 86.8% to be poor. In relation to general characteristics and health habits, the rate of the group who had poor quality sleep was significantly higher in those with a lower subjective health status, in the non-smoking group, and in the low sleep-quality group, compared to the good sleep-quality group. For occupational characteristics, the rate of those with poor quality sleep was significantly higher in groups such as the fire suppression group, the shift work group, the hard physical labor group, the group with a lower sense of satisfaction in their work, and in the group classed as unfit for the job but who were not considering quitting their jobs, compared to their respective counterparts. Multiple regression analysis revealed factors of influence with explanatory powers of 24.4% for subjective health status, alcohol use, subjective quality of sleep, career, job position, and physical labor. The results of this study suggest that the quality of sleep for firefighting officers is significantly related to general characteristics, health-behavioral characteristics, and occupational characteristics.

Purpose: The purpose of this study was to investigate the effects of shift work and hours of sleep on metabolic syndrome in Korean workers. Methods: This study used the Korean National Health and Nutrition Examination Survey data of 2014. The study included 1,579 Korean workers aged over 20. $x^2$ test, t-test, and hierarchical multiple logistic regression were used for statistical analysis of data. Results: From the univariate analysis, hours of sleep, regular work, occupational group, sex, age, marital status, education, smoking, and self-rated health were significantly related to metabolic syndrome. After adjusting demographic, occupational, and health-related variables, workers with under 6 hours/day of sleep showed higher risk for metabolic syndrome (AOR: 1.56, 95% CI: 1.01~2.44), and shift work was not significantly related to metabolic syndrome. Male laborers and workers aged 40 or older also showed higher risk for metabolic syndrome. Conclusion: Results of this study suggest that workers with under 6 hours of sleep, male laborers and workers aged 40 or older are the risk groups of metabolic syndrome. Therefore, prevention and management program for metabolic syndrome should be implemented for this population.
