Purpose: The prevalence of metabolic syndrome (MetS), a cluster of metabolic abnormalities has rapidly increased in Korea. Sleep may play a role in determining its prevalence. However, the relationships between MetS and the duration and quality of sleep are not yet clear. This study aimed to examine the associations between the duration and quality of sleep and the prevalence of MetS. Methods: Study participants included 348 Korean blue-collar workers employed by six small-sized companies in Korea. The data were collected using an interviewer-administered questionnaire, and logistic regression analysis was conducted to estimate the effects of the factors related to MetS. Results: The multiple logistic regression analysis revealed that the independent factors that contributed to the prevalence of MetS were being male (adjusted odds ratio [aOR]=4.87, 95% confidence interval [CI]=1.58~15.0) and lower sleep quality (aOR=5.12, 95% CI=1.90~14.30). Sleep duration was related to the prevalence of some MetS components, but it was not associated with MetS prevalence. Conclusion: Sleep quality was negatively associated with MetS prevalence when covariates, such as sleep duration, were controlled. When developing a MetS risk-reduction program, focus should be given to sleep quality as well as sleep duration in an intervention for Korean blue-collar workers.

This study was conducted to determine family factors related to obesity of high school students. A descriptive correlational study was conducted with 384 high school students in I metropolitan city. Data were collected from February to April of 2015 using self-report structured questionnaires. Questionnaires included weight, height, individual characteristics of subjects and their familial characteristics. Collected data were analyzed by multiple logistic regression. Logistic regression analysis revealed that male gender (aOR = 4.37; 95% CI [1.26, 15.16]), having a non-regular paternal job (aOR = 3.10; 95% CI [1.15, 8.40]), and not being in a two parent family (aOR = 3.52; 95% CI [1.29, 9.61]) were statistically significant contributors to obesity. These results indicate that it is necessary to improve social awareness regarding the obesity risk of male adolescents. Health care providers should recognize the importance of family factors such as parental socioeconomic status and family structures.

Rapid shift to western dietary patterns and social drive of thinness would lead to increase the likelihood of developing eating disorders. This study was performed to analyze the associated factors between dietary pattern and self visualization in terms of body shape, which may increase the risk of disturbed eating attitudes among high school students in Korea. A cross-sectional study was conducted from 2009 to 2010 for high school students including both male and female students, from 6 schools in Gyunggi Province, Korea. A total of 766 students self-reported a questionnaire, including weight control practice, perceptions of self body image and ideal body image, dietary habit, and EAT-26 (Eating Attitude Test-26). Logistic regression analysis was used to fine the factors potentially associated with disturbed eating attitudes. Statistical analysis was conducted using SAS program (version 9.1). Results showed that disturbed eating attitudes were found in 8.7% of male high school students, and in 20.8% of female high school students. Experience of body weight control was reported by 56.2% of male students and by 87.3% of female students. According to multiple logistic regression analysis, obesity was independently associated with high risk of disturbed eating attitudes in male students [Odds Ratios (OR) 2.96, 95% Confidence Interval (CI) 0.90-9.71]. Body image dissatisfaction (OR 2.77, 95%CI 1.37-5.62) and extended family type (OR 2.70, 95%CI 1.05-6.90) were independently associated with high risk of disturbed eating attitudes, especially in female students. In conclusion, proper efforts in education for obesity and developing self-esteem to reduce the risks of disturbed eating attitudes should be implemented in high school nutrition program.

Objectives: The purpose of this study was to examine the association between depression and poor oral health in Korean elderly using Korean version of the Patient Health Questionnaire-9 (PHQ-9) for assessment of depressive symptoms. Methods: This study used the data from Korean National Health and Nutrition Examination Survey (KNHANES VI-2). The study included 1,454 elderly Korean aged over 65. Variables included demographic characteristics (gender, age), socioeconomic factor (income, education), systemic diseases, oral health related factor (tooth brush, dental products), health related factor (alcohol drinking, smoking), and depression. Logistic regression analysis was used as sequential models. Effects were quantified as odds ratios (OR) and 95% confidence intervals (CI). Results: From frequency analysis, being female, primary school or less, non-alcohol drinking, poor oral health were significantly related to depression. In the multiple logistic regression model, depression was significantly associated with poor oral health (OR=1.96, CI=1.15-3.53) after adjustment for other covariates including demographic characteristics, socioeconomic factor, systemic diseases, oral health related factor, and health related factor (OR=1.91, CI=1.13-3.27). Conclusions: Depression had an influence on the poor oral health after adjustment as confounding variable in the elderly. It should be focused on the health promotion for the elderly vulnerable to depression and poor oral health. The development of the mental health and oral health should be established.

BACKGROUND/OBJECTIVES: Low consumption of fruit and vegetable is frequently viewed as an important contributor to obesity risk. With increasing childhood obesity and relatively low fruit and vegetable consumption among Thai children, there is a need to identify the determinants of the intake to promote fruit and vegetable consumption effectively. SUBJECTS/METHODS: This cross-sectional study was conducted at two conveniently selected primary schools in Nakhon Pathom. A total of 609 students (grade 4-6) completed questionnaires on personal and environmental factors. Adequate fruit and vegetable intakes were defined as a minimum of three servings of fruit or vegetable daily, and adequate total intake as at least 6 serves of fruit and vegetable daily. Data were analyzed using descriptive statistics, the chi-square test, and multiple logistic regression. RESULTS: The proportion of children with a sufficient fruit and/or vegetable intakes was low. Covariates of child's personal and environmental factors showed significant associations with sufficient intakes of fruit and/or vegetable (P < 0.05). Logistic regression analyses showed that the following factors were positively related to sufficient intake of vegetable; lower grade, a positive attitude toward vegetable, and fruit availability at home; and that greater maternal education, a positive child's attitude toward vegetable, and fruit availability at home were significantly associated with sufficient consumption of fruits and total fruit and vegetable intake. CONCLUSIONS: The present study showed that personal factors like attitude toward vegetables and socio-environmental factors, such as, greater availability of fruits were significantly associated with sufficient fruit and vegetable consumption. The importance of environmental and personal factors to successful nutrition highlights the importance of involving parents and schools.

Objectives : This study was performed using a longitudinal approach to explore the predictors for current smoking among male high school students. Methods : Baseline data was collected in May 2004 through a self-administrated questionnaire completed by 607 male students in a technical high school in Daegu city, Korea. Subsequently, their smoking behaviors were followed one year after. Among the 544 followed participants, data for 439 non-smokers in the first year was used in longitudinal analysis. Current smokers were defined as those respondents who had smoked one or more cigarettes within the 30 days preceding the survey. Several potential predictors for smoking were investigated including smoking history(never, experimental, former smoker), sociodemographic factors, environmental factors, attitudes toward smoking, and behavioral factors. Logistic regression was used to predict smoking with SPSS ver. 12.0. Results : According to multiple logistic regression analysis, those students who were more likely to smoke after one year were former smokers(OR: 2.12, 95% CI=1.01-4.44), current drinkers(OR: 2.55, 95% CI=1.33-4.89), who had four or five smokers among five best friends(OR: 3.43. 95% CI=1.14-10.30). In addition, those who had smokers among family members besides parents or siblings(OR: 1.66, 95% CI=0.92-2.98), exhibited a high level of subjective stress(OR: 1.77, 95% CI=0.96-3.26), or had a very good relationship with friends(OR: 1.93, 95% CI=0.99-3.75) were also more likely to smoke albeit with marginal statistical significance(p<0.1). Conclusions : A smoking prevention program aimed at high school students may be more effective with due consideration of the predictors highlighted in this study. However, further studies with larger sample size and various target populations are necessary to find potential predictors not found in this study but suggested in other longitudinal studies.

Purpose: This study was done to investigate the types of breastfeeding visits by mothers twenty-four months after birth and to identify the factors that increased breast feeding rates. Methods: The subjects of this study totaled seven hundred and seventy-four mothers with infants aged 2 years or less who had visited national medical institutions including Sanhujori service facilities, breastfeeding care service facilities, and community health centers. Data was collected from June 22 to July 31, 2009. Data was analyzed using descriptive statistics, $x^2$ test, ANOVA with a post hoc Scheffe test, and multiple logistic regression. Results: Major findings of this study were significant differences of planned length of breastfeeding and breastfeeding self-efficacy in relation to the differing types of breast feeding community visits by mothers. In multivariate logistic regression, baby's age, exclusive breastfeeding at hospital, utilization of breastfeeding care service facility, planned length of breastfeeding, and breastfeeding self-efficacy were independent predictors of the feeding type. Conclusion: In order to increase breastfeeding rates, programs provided by public health care services and medical facilities should start education on breast feeding in the hospital before mothers are discharged and then continue through the use of Sanhujori service facilities and workplace at 3 month and 6 month postpartum.

Objectives: The aim of this study was to identify the association between cohabitation status and sleep quality in family members of people with dementia (PwDs). Methods: Data of 190 365 participants aged ≥19 years from the 2018 Korea Community Health Survey were analyzed. Participants were categorized according to their cohabitation status with PwDs. Multiple logistic regression and ordinal logistic regression analyses were performed to evaluate the relationship between the cohabitation status of PwDs' relatives and sleep quality measured using the Pittsburgh Sleep Quality Index (PSQI) and PSQI subscales. Results: Compared to participants without PwDs in their families, both cohabitation and non-cohabitation with PwDs were associated with poor sleep quality (cohabitation, male: odds ratio [OR],1.28; 95% confidence interval [CI], 1.08 to 1.52; female: OR, 1.40; 95% CI, 1.20 to 1.64; non-cohabitation, male: OR, 1.14; 95% CI, 1.05 to 1.24; female: OR, 1.23; 95% CI, 1.14 to 1.33). In a subgroup analysis, non-cohabiting family members showed the highest odds of experiencing poor sleep quality when the PwD lived alone (male: OR, 1.48; 95% CI, 1.14 to 1.91; female: OR, 1.58; 95% CI, 1.24 to 2.01). Cohabiting male and female participants had higher odds of poor subjective sleep quality and use of sleeping medications than non-cohabiting male and female participants, respectively. Conclusions: The residence of PwDs and cohabitation status may contribute to poor sleep quality among PwDs' family members. The circumstances faced by cohabiting and non-cohabiting family members should be considered when evaluating sleep quality in family members of PwDs, and appropriate interventions may be needed to improve sleep quality in both cohabiting and non-cohabiting family members.

Objectives : The purpose of this study was to investigate the prevalence and risk factors of suicidality among community-dwelling elderly. Methods : The participants were 2,201 elderly people whose ages were over 65. The participants were asked to complete questionnaires, including Mini International Neuropsychiatric Interview(MINI), module C, Short Geriatric Depression Scale of Korean version(SGDS-K), Korean Geriatric Anxiety Inventory(K-GAI), The Korean Health Status Measure for Elderly V 1.0, Korean version of Mini-Mental Status Examination for Dementia Screening(MMSE-DS). Their sociodemographic factors were investigated. The data were analyzed using the chi-square test and the logistic regression test to examine the relationship between suicidality and participants' risk factors. Results : The prevalence rate of suicidality was 23.3%. In multiple logistic regression, depressive symptoms (OR=3.301, 95% CI : 2.453-4.440), anxiety symptoms(OR=3.289, 95% CI : 2.515-4.303), low physical function (OR=1.606, 95% CI : 1.229-2.098), no spouse(OR=1.571, 95% CI : 1.037-1.690), elderly aged 80 years or older (OR=1.506, 95% CI : 1.094-1.740) were independently associated with suicidality. Conclusion : Suicidality in community-dwelling elderly was quite high, particularly related to depressive symptoms. The results of this study can be useful for development of community-based prevention and management programs for suicidality.

Purpose: This study aimed to investigate the relationship between emergency medical service accessibility in different regions and the sudden death rate in elderly patients with ischemic heart disease using data analysis techniques and suggest improvements in regional emergency medical services. Methods: The study collected data from the NEDIS database and Statistics Korea. Data on a total of 75,867 patients aged ≥65 years were reviewed among patients with ischemic heart disease who visited emergency medical institutions in 2018. Frequency analysis, chi-square test, multiple logistic regression analysis, and simple logistic regression analysis were performed using SPSS PC Window 25.0. Results: With an emergency medical resource per 100km², there was a concomitant reduction in the risk of death. There was a decrease in the death rate by 0.967, 0.970, 0.997, and 0.391 times with the increase in the presence of a fire department, an ambulance, a paramedic, and a regional medical center, respectively. Furthermore, a decrement in the death rate was witnessed 0.844, 0.825, and 0.975 times with the initiation of a local emergency medical center, a local emergency medical institution, and an angiography device, respectively(p <.001). Conclusion: To improve the accessibility of emergency medical services, the population and geometric area of the region should be considered essential factors when deploying emergency medical resources.
