Background: Sleep disorder is a precursor to depression, which is one of the psychological factors associated with periodontal disease that, in turn, affects general and periodontal health. This study aimed to investigate the relationship between sleep duration, depression, and periodontitis in older people aged over 65 years. Methods: A total of 2,002 older adults aged 65 years or older were included in the study. Their general and health aspects, including smoking, drinking, diabetes, hypertension, and depression, were investigated. Periodontitis was examined using the Community Periodontal Index (CPI). Data were analyzed through a complex sampling design method. Frequency and crossover analyses were conducted to investigate the relationship between depression and periodontitis. To investigate the effect of depression on periodontitis, a logistic regression analysis was performed. Results: Regarding depression and participants' general characteristics, statistically significant differences were found in sex, economic activity, smoking habit, and CPI (p<0.05). In the presence of depression, the odds ratio for periodontitis was 1.84, and the adjusted odds ratio for age, sex, economic activity, residence type, household income, education level, smoking habit, drinking, hypertension, and diabetes was 1.72, representing a significant difference (p<0.05). Conclusion: This study examined the relationship between depression and periodontitis in older persons and confirmed a significant correlation. As the population of older adults increases, we should pay attention to their mental and oral health as well as systemic diseases. Various programs for the health promotion of older persons need to be implemented to improve the quality of life of older people.

Purpose: The aim of this research was to identify the mediating effect of sleep quality on the relationship between job stress and stress response of shift-working nurses. Methods: The participants in this study were 150 nurses who had more than 6 months of shift-working experience. A survey was conducted from May to June 2017 in a hospital in Gyeonggi-do, South Korea. The data were collected through self-report questionnaires. The collected data were analyzed using SAS 9.4 program. The analysis was based on Baron and Kenny's model to examine the mediating effects of sleep quality on the relationship between job stress and stress response of shift-working nurses. Results: In the first and second steps, job stress was identified as a significant predictor of sleep quality (β= .29, p= .001) and stress response (β = .24, p= .004). In the third step, sleep (B = .55, p< .001) was observed as a significant predictor of stress response, and the direct relationship between job stress and stress response was not significant (β= .07, p= .291). Sleep quality was found to exhibit complete mediating effect on the relationship between job stress and stress response. Conclusion: The results of this study suggest that strategies for managing the stress of shift-working nurses should include effective ways to ensure sleep quality.

Purpose: The purpose of this study was to identify the prevalence, subtypes and risk factors of Irritable Bowel Syndrome (IBS) among male adolescents. Methods: The survey was conducted on male adolescents (n=441) attending a high school. Rome IV criteria was used to diagnose IBS. Data on health promoting behaviors, psychological distress, sleep hygiene practices were collected using self-administered structured questionnaires. Results: The prevalence of IBS was 11.1% and the subtypes were mixed (77.5%), unclassified (10.2%), diarrhea-predominant (8.2%), and constipation-predominant (4.1%). Risk factors influencing IBS were sleeping time (Odds Ratio [OR]=1.00, 95% Confidence Interval [CI]: 0.99~1.00), anxiety, a subfactor under psychological distress (OR=1.12, 95% CI: 1.02~1.22), and arousal-related behaviors, a subfactor under sleep hygiene practices (OR=1.10, 95% CI: 1.03~1.17). Conclusion: Our findings indicated that IBS is a common problem in male adolescents. It is necessary to develop school-based intervention strategies addressing sleeping time, anxiety and arousal-related behaviors in order to prevent and improve IBS in male adolescents.

This study aimed to analyze the impact of sleep deprivation (SD) on cardiac, hemodynamic, and endothelial parameters and to determine whether these are sustained with increased periods of SD. The study included 60 healthy men (mean: age $31.2{\pm}6.3years$; body mass index $24.6{\pm}2.6kg/m^2$). Hemodynamic parameters, parameters of myocardial contractility, spectral analysis of heart rate (HR) and blood pressure (BP) variability, and the sensitivity of arterial baroreflex function were evaluated. Biochemical tests were performed to assess L-arginine (L-Arg) and asymmetric dimethylarginine (ADMA) levels in reflection of endothelial nitric oxide synthase ability. Measurements of cardiovascular system parameters were obtained at 9 a.m. (baseline) on the first day of the study and 9 a.m. (24-h SD), 1 p.m. (28-h SD), and 5 p.m. (32-h SD) on the second day. Blood samples for evaluating biochemical parameters were obtained at baseline and after 24-h SD. ANOVA Friedman's test revealed a significant effect for time in relation to HR (${\chi}^2=26.04$, df=5, p=0.000), systolic BP (${\chi}^2=35.98$, df=5, p=0.000), diastolic BP (${\chi}^2=18.01$, df=5, p=0.003), and mean BP (${\chi}^2=28.32$, df=5, p=0.000). L-Arg and ADMA levels changed from $78.2{\pm}12.9$ and $0.3{\pm}0.1$ at baseline to $68.8{\pm}10.2$ and $0.4{\pm}0.1$ after 24-hr SD, respectively (p=0.001, p=0.004). SD in healthy men is associated with increases in BP, which appear to occur after 24 hours of SD and are maintained over increasing periods of SD. The observed hemodynamic changes may have resulted due to disordered vascular endothelial function, as reflected in alterations in L-Arg and ADMA levels.

Objectives : The study investigated and analyzed the relationship between health-related lifestyle and psychosomatic self-reported symptom in dental hygiene students. Methods : A self-reported questionnaire was filled out by 478 dental hygiene students in Gyeonggi-do and Gangwon-do from March 7 to June 21, 2012 by random sampling method after informed consent. Results : The health-related lifestyle showed the results as follows. Nonsmokers accounted for 89.1%. Those who never exercise accounted for 67.9% and 37.9% of the students sleep for 5-6 hours. Those who take alcohols twice per month accounted for 58.2%. The correlation between the symptoms and lifestyle included multiple subjective symptoms(I), respiratory(A), eyes and skin(B) and digestive organs(C) symptoms and smoking status(p<.01), mouth and anal(D), depression(K), nervousness(E). There existed the correlation in average sleeping time(p<.01) and impulsivess(H) and smoking status(p<.05) and lie scale(L) and regular exercise(p<.05) and aggressiveness(F) and drinking habits and irregular and life(G) and breakfast habits. The smoking habit, sleeping time, and snack intake had an influence on psychosomatic self-reported oral health-related symptoms. Conclusions : Cessation of smoking, adequate sleeping time, and reduction of snack intake can improve the oral health-related lifestyle and reduce the self-reported symptoms in the dental hygiene students.
