Objectives. Few studies have attempted to explain the association between socioeconomic status (SES) and obesity in Korea Especially the studies on same race with different SES at same time are good for SES influence estimation. The present study highlights the influence of SES of parents on adolescent obesity. The subjects are the same race, but live in different areas, with different SES, Seoul and Yangpung in Korea, and Yanbian in China. Methods. The cross-sectional study was conducted in Mar-Jun 1996. We carried out anthropometry, 24 hour-recall diet survey, self-reported questionnaire about sociodemographic characteristics and physical activity. For SES indicators, we used income and education of parents. Results. The relationship between SES of parents, defined as educational status, and obesity in boys in Korea and China is direct, but not significant. The relationship is inverse and nonsignificant among Korean girls, However, for the Korean girls in severe obesity, the relationship is significant. For the Korean-Chinese girls, there is an inverse relationship between the education level and obesity but a direct relationship between the income level of parents and obesity. For the Korean adolescent, there are a direct association between the SES of parents and the nutrients factors such as energy, protein, and fat intake. The energy expenditure of adolescent has no relationship with SES of parents. Conclusion. Among boys, the higher the SES, the greater the risk of obese. Among girls in Korea and Korean-Chinese, on the other hand, the lower the educational status of parents, the greater the risk of obese.

Objectives: The aim of this study was to measure secular trends in health risk behaviors among middle and high school students in Korea between 2005 and 2009 by using data from the Korea Youth Risk Behavior Web-based Survey(KYRBS). Methods: The analyses were performed using data from the 2005, 2006, 2007, 2008, and 2009 KYRBS, which included a nationally representative sample of middle and high school students. A total of 34 health behavior indices were used for the assessment of secular trends in health risk behaviors. Logistic regression models were used to identify statistically significant secular trends in health risk behaviors, after adjusting for gender and grade. Linear and higher-order time variables were simultaneously entered into the statistical models. Results: There was evidence of small, but statistically significant increasing or decreasing trends in certain health risk behaviors. Secular trends in health risk behaviors varied by gender. Conclusions: This study indicates that between 2005 and 2009, changes in health risk behaviors among Korean adolescents were generally small, but represented statistically significant increases or decreases. Further research should explore why certain health risk behaviors are increasing or decreasing and what types of interventions are most effective.

The purposes of this study were to investigate the relationships between the degree of physical pain and the knowledge and preventive actions of musculoskeletal diseases among dental hygiene students with a potential risk of contracting those diseases and thus to help them prevent them. A survey was taken among 207 sophomores and juniors specializing in dental hygiene at S1 and S2, Gyeonggi Province in the area of physical pain, knowledge of musculoskeletal diseases, and preventive actions against them. The findings were as follows: 1. The mean scores of the sophomore in the knowledge of musculoskeletal diseases were $6.20{\pm}2.21$, and those of the juniors were $6.72{\pm}2.29$. The mean scores of the sophomores and juniors in the preventive actions against musculoskeletal diseases were $22.50{\pm}2.37$ and $22.29{\pm}3.01$, respectively. 2. The subjects displayed severe physical pain in the lower back, shoulder, and neck in the descending order and medium physical pain in the neck, shoulder, and lower back in the descending order. 3. The higher level knowledge of musculoskeletal diseases they had, the less physical pain they felt. And there were significant differences among the shoulder, lower back, hip, ankle, and foot. 4. There were relationships between physical pain and the preventive actions against musculoskeletal diseases in "placing the hands at the height of the elbows during treatment", "reducing such positions as bending and extending during treatment", "narrowing the distance with the patient", "taking regular breaks during treatment for recovery", "trying not to incline the neck, back, arm, and wrist as much as possible", and "trying to keep the torso in the neutral position." 5. As for the education about musculoskeletal diseases, 74 sophomores(88.10%) and 102 juniors(89.74%) answered they received no such education. The results suggest that there should be some instructions to help dental hygiene students practice the preventive actions against musculoskeletal diseases and further prevention programs against those diseases.

Purpose: This study aimed to investigate the relationships between the level of knowledge, attitude and compliance of preventive behaviors of the Middle East respiratory syndrome (MERS) among nursing students. Methods: The study sample consisted of 219 nursing students. Through the use of a structured questionnaire, data collection was conducted from June 1st to June 30th 2015. The descriptive statistics, independent t-tests and Pearson's correlation coefficient were employed to analyze the data. Results: The score of the MERS-related knowledge was 9.15 out of 13. The participants had a positive attitude toward the MERS. The level of MERS-related knowledge was high in the case of temporary school closure or break in clinical practice because of the clinical training in hospitals that MERS occurred (t= 2.42, p= .016). The compliance level of the preventive behavior for MERS was high in female students (t= -2.11, p= .036), in the case of temporary school closure or break in clinical practice due to the clinical training in hospitals that MERS occurred (t = 3.29, p= .001), and in students that had MERS-related education for prevention (t = 2.80, p= .006). The MERS-related knowledge was positively correlated with the level of compliance for preventive behavior (r= .18, p= .009). Conclusion: To prevent MERS infection in nursing students, the level of knowledge on MERS should be enhanced so that they can practice preventive behaviors against it. Additionally, the MERS infection control education should include etiology and treatment products based on the MERS response guideline issued by the Centers for Korea Disease Control and Prevention.

Objectives: This study aimed to evaluate the association between dental implants and cognitive function in community-dwelling older adults. Methods: Data were collected from the baseline survey (2016-2017) of the Korean Frailty and Aging Cohort Study. The study sample comprised 1115 community-dwelling people aged 70 years to 84 years who had 0-19 natural teeth. Dental implants and natural teeth were identified by panoramic radiography, while the cognitive function was assessed by the Korean version of the Mini-Mental State Examination (MMSE-KC). The association between dental implants and cognitive function was analyzed by multiple linear regression. Sensitivity analysis was performed to test for potential bias. Results: The mean number of natural teeth in the study population was 9.50 (standard deviation [SD], 6.42), and the mean MMSE-KC score was 24.93 (SD, 3.55). In the simple univariate analysis, tooth replacement, age, sex, smoking status, alcohol consumption, body mass index, osteoporosis, number of natural teeth, periodontitis, chewing discomfort, tooth-brushing frequency, education level, monthly household income, participation in economic activity, living alone, and marital status had a significant impact on the association. After adjusting for confounders, the association between dental implants and cognitive function remained significant (B, 0.85; standard error, 0.40; p<0.05). Age, body mass index, periodontitis, tooth-brushing frequency, and education level were also significantly associated with cognitive function. The results of the sensitivity analyses were consistent with those of the primary analysis. Conclusions: Dental implants were associated with cognitive function in older adults living in the community. Dental implants as tooth replacements may play a role in preserving cognitive function.

Purpose: This study aimed to explore factors influencing on the preventive behaviors of dementia in older Koreans enrolled in senior welfare centers to provide basic information on dementia prevention. Methods: A total of 182 older Koreans participated in this study, which employed a cross-sectional design. Data were collected using questionnaires with items related to general characteristics, depression, self-esteem, knowledge and attitudes about dementia, preventive behaviors of dementia, dementia management self-efficacy, and anxiety about dementia. Using SPSS WIN 23.0, data were analyzed by descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficient, and multiple regression. Results: Living with a spouse (p=.013), a higher monthly income (p=.018), better nutrition (p=.010), not having a sleep disorder (p<.001), and higher number of participating programs (p=.001) were associated with better dementia prevention behaviors. Attitudes about dementia (��=.18, p=.006) and the number of programs older Koreans were participating in (��=.17, p=.006) influenced positively on the preventive behaviors of dementia, while depression (��=-.41, p<.001) and sleep disorders (��=-.17, p=.006) influenced negatively on dementia preventive behaviors. Overall, approximately 35% of the variability in dementia preventive behaviors was explained by these four variables in this study (F=24.97, p<.001). Conclusion: The findings of this study suggest that depression reduction, good attitudes about dementia, program participation, and good sleep should be encouraged to promote dementia prevention. In addition, effective and structured educational programs should be developed for older Koreans to encourage dementia preventive behaviors to reduce the risk of dementia.

Objectives: This study aimed to identify the factors related to the completion status of continuing education and to help develop professional ability by presenting improvement directions. Methods: A questionnaire survey involving 500 dental hygienists working at 155 dental clinics in Gwang-ju was conducted between June 19 and July 29, 2017. Descriptive analysis, chi-square tests, and t-tests were conducted using Statistical Package for Social Sciences Version 21.0 for Windows. Finally, to investigate the factors related to the completion of continuing education, logistic regression analysis was performed. Results: The odds ratio (OR) was higher in the group with more than 16 years of total work carrier (OR=3.40, 95% confidence interval (CI)=1.22-9.45) than that in the group with 1-5 years of work carrier. Groups receiving information from associations (OR=5.35, 95% CI=1.74-16.40), groups that directly search for information (OR=6.53, 95% CI=1.84-23.12), and groups receiving information from colleagues (OR=3.55, 95% CI=1.17-10.77) had higher ORs than groups receiving no information. The OR was higher in the group receiving cost support for participation (OR=2.20, 95% CI=1.06-4.55) than the group receiving no support. Regarding total education completion status in 2012-2014, groups that completed grades 1-7 (OR=2.51, 95% CI=1.35-4.64) and those that completed grade 8 or higher (OR=14.37, 95% CI=7.68-26.89) had higher ORs than groups who received no education. Conclusions: The rate of completion of continuing education can be increased by reviewing the course contents, publicity activities, and cost of continuing education.
