The purpose of this study was to develop and validate of Smoker Image Scale and to evaluate the effect of the smoker image on adulthood smoking intention of youth. Data were collected from 610 high school students were analysed using SPSS 21.0 and AMOS 21.0 programs. Smoker Image Scale were developed and verified the reliability and validity. In addition, ordinal logistic regression analysis was implemented for impact of smoker image on adulthood smoking intention. As a results of analysis, first, the developed Smoker Image Scale confirmed with 10 items in 1 factor and Cronbach's ${\alpha}$ was .91. Second, men and smokers had significantly higher positive smoker image formed by cigarette advertising. Third, positive smoker image had a significant positive effect on adulthood smoking intention while controlling of gender and smoking status. Positive smoker image formed by cigarette advertising was associated with adulthood smoking intention of youth. Based on these findings, implications and suggestions for future research were discussed for the risk of adulthood smoking intention of youth.

Objective: Diminished ovarian reserve (DOR) is a disorder characterized by impaired ovarian function. Sleep disorders are disruptions of the circadian rhythm, which appears to be closely linked to reproductive systems. This study aimed to investigate the impact of poor sleep quality on the ovarian reserve of childbearing-age women. Methods: A cross-sectional study was conducted in China from June 2021 to March 2023. In total, 102 participants diagnosed with chronic insomnia disorder were included in the study. Questionnaires were administered to assess participants' menstrual patterns, insomnia severity, anxiety, and depression. The anti-Müllerian hormone level and the basal antral follicle count were measured for ovarian reserve evaluation. Correlation analysis and ordinal logistic regression analysis were conducted. Results: The women with insomnia presented high percentages of hypomenorrhea, premenstrual syndrome, and dysmenorrhea (78.4%, 74.5%, and 46.1%, respectively). Severe sleep disorder in the past month was identified as an independent risk factor for hypomenorrhea and premenstrual syndrome (odds ratio [OR], 2.64 and OR, 2.688; p<0.05). The prevalence of DOR among women with insomnia (33.3%) was significantly higher than the average reported in previous studies for young women. Insomnia duration exceeding 1 year was determined to be an independent risk factor for DOR in women aged 36 to 40 years (OR, 4.5; p=0.033). Conclusion: This study highlights the association between sleep disorders and menstrual problems. Prolonged poor sleep quality in women aged 36 to 40 years was identified as a significant risk factor for DOR. We should pay more attention to improving sleep quality in order to maintain normal ovarian function.

Purpose: This study was done to investigate the practice level of 14 health behaviors between male (N=139) and female (N=175) elderly and to identify the barriers to each health behavior of elderly people in Korea. Methods: Data were collected from 314 elderly people (65yr and older) living in metropolitan, urban, and rural areas. Descriptive statistics, $x^2$-test and ordinal logistic regression were used in data analysis using the SPSS Win 15 version. Results: 1) The performances were different in some health behaviors between male and female elderly people. Male elderly showed better performances in balanced diet, regular exercise, and more than 30 min of exercise, while female elderly showed better performances in restriction of fat and cholesterol, restriction on alcohol, and smoking. There were no differences in stress management and health prevention behaviors between the two groups. 2) The common significant barriers in health behaviors of the elderly in Korea were the lack of habit and physical discomfort. However, the lack of perceived benefit was a significant barrier in male elderly. Lack of time and lack of family support were significant barriers in female elderly people in Korea. Conclusion: These results suggest that tailored strategies should be developed considering the gender difference to reduce the main barriers of each health behavior in order to improve the health status of elderly people.

Although researches have highlighted the important role of enhanced farm biosecurity to reduce the severity and prevalence of diseases in livestock, to date there has been little study in Korea on farmers' adoption of biosecurity measures to control porcine reproductive and respiratory syndrome virus (PRRSV) infection. To mitigate the risk of PRRSV infection in pigs, the risk factors by which PRRSV is introduced in pig farms must be determined. The primary aim of this study was to investigate pig producers' perceptions about on-farm biosecurity practices. We also analyzed data obtained from a cross-sectional study on 196 farrow-to-finish farms conducted between March 2013 and February 2014 to identify risk factors for PRRSV infection at farm level. Standardized questionnaires with information about basic demographical data and management practices were collected in each farm by on-site visit of trained veterinarians. Farms were classified as negative or positive through the use of infection profiles that combined data on PCR positive pigs and serological testing including antibody titer, sero-conversion pattern at each age category, and vaccination status. Data on biosecurity practices, farm management and environmental characteristics were analyzed using multivariate ordinal logistic regression. Generally, the biosecurity level in the pig farms included in this study were insufficient to reduce/prevent the risk of PRRSV infection given the high pig density areas and the considerable extent of vehicle movement. Factors associated with PRRSV infection were those where owners used on-farm vaccination programs had a lower risk of infection (OR = 0.19, 95% CI 0.06-0.61). The results from the analysis may guide to tailor biosecurity measures in the reduction or prevention of PRRS to the specific circumstances of pig farms in different localities of the world. To the best knowledge of the authors, this is the first study to report information on the biosecurity practices currently implemented on Korean pig farms.

The purpose of this study was to investigate the association of blood pressures, hematological and blood biochemical properties according to the degree of obesity based on differential combinations of BMI in health checkup examinees. Study subjects were 3,731 adults of 20 years and over (2,312 males, 1,419 females), not recognized as taking medicines for or having cardiovascular diseases, who underwent health package check-up at the Korea Association of Health Promotion, Daejeon Branch from Jan. 2007 to Dec. 2009. As a results, the mean values of SBP, DBP, TG, TC, LDL-C, ALT, AST, GGT, ALP were significantly increased with higher level of BMI, but the HDL-C was significantly decreased with higher level of BMI. On correlation of BMI with various factors, the BMI was positively correlated with SBP, DBP, TG, TC, LDL-C and GGT, while the HDL-C was negatively correlated. Based on the result of ordinal logistic regression analysis, the risk ratio to the abnormal level of SBP, DBP, TG, ALT and GGT were significantly increased as BMI increased.

Purpose: The purpose of this study is to identify the dietary habits of Korean adolescents and to investigate their effects on sleep duration. Methods: This study is a secondary analysis drawn from the 2016 Korean Youth Risk Behavior Web-Based Survey (N=65,528). ANCOVA was used to determine the relationship between dietary habits and sleep duration. Ordinal logistic regression was used to find out the effects of dietary habits on sleep duration adjusted for general characteristics and behavioral characteristics. Results: The group that consumed no breakfast (AOR=0.89, p<.001) had less sufficient sleep duration than those who had breakfast 7 times per week. The group that had drunk no milk (AOR=0.88, p<.001) had less sufficient sleep duration than those who enjoyed it 5 times per week. On the contrary, the groups that had no soda drinks (AOR=1.18, p=.015), caffeine drinks (AOR=1.77, p<.001), and sweet drinks (AOR=1.25, p<.001) were more likely to have sufficient sleep duration than the groups that consumed those beverages 5 times per week. Conclusion: It is important to educate adolescents about healthy eating habits including drinks and optimal sufficient sleep duration through a multidisciplinary approach.

Background: In this study, we investigated the changes and factors that affect daily health behaviors due to COVID-19 among adolescents. We intend to provide basic data so that a systematic and comprehensive health education program that includes physical and oral health can be made. Methods: This study was a secondary data analysis of the from the 2019 and 2020 Korea Youth Risk Behavior Web-based Survey. A final sample of 112,251 participants was anlayzed using chi-square test, and ordinal logistic regression. Results: In the case of tooth brushing, the frequency of 'never' increased in most general characteristics compared to before COVID-19. In the case of handwashing, it was found that handwashing behavior increased (increased) after COVID-19 compared to before COVID-19. As a result of confirming the factors affecting tooth brushing behavior before and after COVID-19, it was found that girls brushed teeth 2.2 times more regularly after lunch than boys. As a result of adjusting all other factors, regular tooth brushing behavior after COVID-19 was reduced by 0.79 times compared to before COVID-19. Conclusion: It is judged that it is necessary to operate a comprehensive health management program in the school so that the most basic tooth brushing for oral health and handwashing for health can become a habit. In addition, by confirming the impact of the COVID-19 pandemic on handwashing and tooth brushing behavior through this study, it is expected to be used in the development of policy data such as raising awareness of brushing and improving behaviors applicable in the current and upcoming new pandemic situations.
