Objectives: This study was conducted to observe recent changes in adolescents' dietary behavior and indirectly evaluate the effects of the government's nutritional policies in Korea. Methods: We analyzed the secular trends in seven dietary behaviors using the Korea Youth Risk Behavior Web-based Survey data from 2005 to 2009. Through literature review, we included the policies implemented for the improvement of adolescents' dietary behaviors during the same periods. Results: The significant linear trends were observed in all dietary behaviors (p<0.05). Overall, all behaviors except the fruit intake rate were desirably changed during five years but undesirable changes were observed between 2008 and 2009 in all behaviors. Within those periods, several policies were implemented including 'Ban on carbonated-beverages in school', 'Green Food Zone', etc. Despite confirmed evidence of their effects, the policies on individual behavior such as nutrition education didn't influence the prevalence of dietary behaviors because they were conducted to too limited persons. Polices on the school environmental improvement, such as ban on carbonated beverage in school, were more effective because they decreased the exposure of undesirable food environment. However, for effect of Green Food Zone improving community environment we couldn't come to a conclusion because of too short period after full implementation. Conclusions: Among government nutrition policies conducted from 2005 to 2009, those on environmental improvement, especially in school, were more effective than those on individual behavior. Therefore, the development and implement of policies on school environmental improvement are needed in Korea.

Objectives: Given the increase in osteoporosis among health volunteers and the effect of health literacy on the adoption of nutritional preventive behaviors, this study aimed to determine the effects of an educational intervention on health literacy and the adoption of nutritional preventive behaviors related to osteoporosis among health volunteers. Methods: This was a quasi-experimental, interventional study of health volunteers conducted in 2020. In this study, 140 subjects (70 in both intervention and control groups) were selected using the random multi-stage sampling method. An educational intervention was conducted using the Telegram application, and educational messages were sent to the health volunteers in the intervention group across 6 sessions. Data were collected via a demographic questionnaire, the Health Literacy for Iranian Adults survey, and a nutritional performance questionnaire, which were completed before and 3 months after the intervention. The data were collected and analyzed using SPSS version 23. Results: Before the intervention, there were no significant differences in the mean scores for health literacy variables and the adoption of nutritional preventive behaviors between the intervention and control groups (p>0.05). After the intervention, there was a significant change in the mean scores for health literacy and the adoption of preventive behaviors in the intervention group (p<0.05) as opposed to the control group. Conclusions: Interventions aimed at increasing health literacy are effective for promoting the adoption of preventive and healthy nutritional behaviors related to osteoporosis.

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.

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.

Purpose: The purpose of this study was to survey the Coronavirus Disease 2019 (COVID-19) related knowledge, risk perception, preventive behaviors, depression, and anxiety levels among nursing students, and to identify factors that influence preventive behaviors. Methods: An online survey was conducted among nursing students from October 7, 2020 to October 12, 2020. The data were analyzed using independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression. Results: A total of 222 nursing students participated in this study. The correct answer rate for COVID-19 knowledge was 90.0%, risk perception was 5.51±1.26, and the rate for preventive behaviors was 92.5%. The depression score was 6.28±4.63; 59.9% of nursing students had depression, and the anxiety score was 5.56±3.98; 59.9% of nursing students had anxiety. COVID-19 preventive behaviors had a positive correlation with COVID-19 knowledge (r= .30, p< .001), COVID-19 risk perception (r= .18, p= .009), and anxiety (r= .21, p= .001). Factors influencing COVID-19 preventive behaviors by multiple regression were identified as COVID-19 knowledge, anxiety, physical health status before and after COVID-19, grade, practical experience after COVID-19, and COVID-19 risk perception (F = 12.46, p< .001, R²= 25.8%). Conclusion: The results of this research on factors influencing COVID-19 prevention behaviors can be used in the future to develop appropriate health policies for individual and community infectious disease prevention behaviors.

Objectives: Adolescents who engage in unhealthy behaviors are particularly vulnerable to anxiety. We hypothesized that participation in physical activity could influence the relationship between anxiety and unhealthy behaviors in adolescents. These behaviors include smoking, alcohol consumption, and unsafe sexual activity. Methods: This study included 50 301 students from the first year of middle school to the third year of high school, all from Korea. The unhealthy adolescent behaviors examined included current alcohol consumption, current smoking, and unsafe sexual behavior. Anxiety levels were assessed using the Generalized Anxiety Disorder-7 questionnaire (GAD-7). Results: The participants had a mean age of 15.19 years and an average GAD-7 score of 4.23. No significant differences were observed in GAD-7 score among exercising participants when categorized by smoking status (p=0.835) or unsafe sexual behavior (p=0.489). In contrast, participants in the non-exercise group who engaged in these behaviors demonstrated significantly higher GAD-7 scores (p<0.001 and 0.016, respectively). The only significant interaction was found between unsafe sexual behavior and exercise (p=0.009). Based on logistic regression analysis, within the non-exercise group, significant positive associations were observed between current smoking and anxiety (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.18 to 1.57), as well as between unsafe sexual behavior and anxiety (OR, 1.33; 95% CI, 1.02 to 1.73). However, within the exercise group, no significant association was found between anxiety and either smoking or unsafe sexual behavior. Furthermore, no significant interaction was observed between unhealthy behaviors and exercise. Conclusions: These findings are insufficient to conclude that physical activity influences the relationship between unhealthy behaviors and anxiety.

This study was conducted to identify the factors related to the cancer preventive behaviors of middle aged women. The data was collected from October $1^{st}$ 2012 to February $10^{th}$ 2013 from 114 middle aged women in four churches in B city. As a result, there were significant differences in the cancer preventive behaviors according to cancer preventive education, concerns about cancer information and the utilization of cancer information. The cancer preventive behaviors were weakly related to the internal health locus of the control, chance health locus of the control and self-esteem. In addition, there was moderate correlation between the cancer preventive behaviors and the external health locus of the control. Meaningful variables that explain the cancer preventive behaviors were the external health locus of the control, self-esteem, cancer preventive education in that order. The total explanation power was 25.3% and the external health locus of the control has most explanation power. In conclusion, it is necessary to develop nursing intervention and health education for middle aged women to raise the internal health locus of the control and self-esteem, and encourage attending cancer preventive education to improve the preventive behaviors against cancer.

The influence of information sensitivity during the COVID-19 pandemic on perceived risk and personal preventive behaviors of consumers in China had been investigated. The participants were Chinese individuals experiencing the pandemic as it happened. Participants voluntarily completed an online questionnaire to provide their COVID-19 information sensitivity, their perceived COVID-19 risk, preventive behavior and their respective age. Our study discovered that COVID-19 information sensitivity positively influence perceived risk and preventive behavior. Moreover, young individuals show higher levels of online information sensitivity, which influenced their personal protective behavior when compared to that of middle-aged and elderly participants. Furthermore, Perceived risk significantly affected preventive behaviors. The results of this study may assist the government and marketeers in comprehending information sensitivity which can affect consumers' protective behavior toward reducing COVID-19 infections.

This study was conducted to explore the levels of Middle East Respiratory Syndrome (MERS)-related knowledge, attitudes and preventive behaviors performance and to identify predictors of MERS-related preventive behaviors performance among clinical practice students in a tertiary hospital. The participants were 480 nursing and medical clinical practice students. Data collection was conducted using self-reported questionnaires in June of 2015 and were analyzed using descriptive statistics, independent t-tests, one-way ANOVA, and hierarchical regression using the SPSSWIN 24.0 program. The MERS-related knowledge (9.56 out of 13 points) was high, attitudes towards MERS, such as severity cognition and prevention about MERS was positive (4.15 out of 5 points), and MERS-related preventive behaviors performance level was moderate (3.02 out of 5 points). Female students, having education experience regarding MERS, taking vaccination for influenza H1N1 infection in the last year, having the intention of taking influenza H1N1 in the current year, having fear of MERS infection, higher knowledge and more positive attitudes about MERS were predictors of better MERS-related preventive behaviors performance. These results show that general characteristics associated with MERS-related preventive behaviors performance should be considered to improve preventive behaviors of clinical practice students. Furthermore, this study highlights the need to develop effective and useful MERS education programs that provide essential knowledge and attitude about MERS that clinical practice students must acquire to promote the MERS-related preventive behaviors performance.

This study was conducted to identify the related factors of cancer preventive behaviors for adolescent smokers. Data were collected from September 1st 2012 to March 31st 2013 of 200 adolescent smokers who were participating in smoking cessation school at W hospital in B city. As a results, there were significant differences in cancer preventive behaviors by grade, religion, benefit, barrier, perceived health status, daily living, alcohol, exercise, nicotine dependency, first smoking age, smoking duration and non-smoking intention. Cancer preventive behaviors were weakly negative related to knowledge about cancer, And there is weakly positive correlation between cancer preventive behaviors and attitude about cancer. Meaningful variables which explain cancer preventive behaviors were daily living, barrier, grade, exercise, benefit, knowledge about cancer, smoking cessation intention in order. Total explanation power was 30.6% and daily living has most explanation power. In conclusion, It is necessary to encourage sound hobbies and exercise instead of smoking for adolescent smokers in their daily living. And health education programmes, based on the grade and smoking cessation intention of adolescent smokers, need to be developed to emphasize the benefit of cancer preventive behaviors, and to decrease barriers against those behaviors.
