Objectives: Thirdhand smoke (THS) refers to residual tobacco smoke pollutants that remain after cigarette smoking. The purpose of this study was to determine predictors of the belief among adults in Korea that THS is harmful to children. Methods: A population-based sample of 3,000 adults (${\geq}19$ years) among a web-based panel in Korea was obtained in November 2016. The respondents filled out questionnaires, including THS beliefs, smoking status, presence of voluntary smoke-free rules at home, and support for the implementation of smoke-free regulations at home. THS beliefs were assessed with a statement that staying in a room today where people smoked yesterday can harm the health of children. Results: Overall, 92.2 % of adults believed that THS exposure could harm the health of children. Respondents who were nonsmokers, believed that SHS exposure were associated with pneumonia of children, lived in home with complete smoke-free rule at home, and supported the implementation of smoke-free regulation at home were more likely to believe that THS could harm for health of children. Conclusions: The majority of Korean adults believed that THS exposure could harm the health of children. Predictors identified in the study can be useful to address the risk of THS beliefs and promote implementation of tobacco control policies.

Objectives: To prevent smoking among adolescents, we should facilitate school-based smoking prevention programs and provide supports for teachers to participate actively in these programs. This study investigated Korean middle teachers' intentions, perceptions, and attitudes toward participating in smoking prevention programs. Methods: The study design was cross-sectional. Our conceptual framework utilized the Theory of Planned Behavior by Fishbein and Ajzen. We conducted open-ended elicitation interviews with teachers. We developed the survey questionnaire contents with data from these interviews, and distributed the questionnaires in 2002 to 194 school teachers from four schools in Seoul and Kyounggi-Do. Teachers' beliefs(behavioral, normative & control) and intentions about participating in smoking prevention programs were measured by 7-point scales. Results: The majority of teachers surveyed reported participating in adolescents' smoking prevention programs, while only less than 10% teachers reported having educational training for such programs. Teachers' attitudes toward participating in smoking prevention programs were positive, but they did not feel strong subjective norms about participating in the programs. They reported several barriers as well as facilitating conditions in participating in those programs. In correlation analysis, teachers' subjective norms and attitudes toward participating in smoking prevention were significantly correlated with their intentions to participating in those programs. Teachers with positive perceptions about smoking prevention programs were more likely to have strong intentions to participation in them, while teachers who received educational training and instructions on how to teach in smoking prevention programs were more likely to have positive perceptions than those who did not. Conclusion: We concluded that smoking prevention programs for adolescents can be made more effective by increasing societal expectations that teachers participate in these programs, and by providing additional resources dedicated to facilitating teachers' active participation in them.

Smoking can increase oxidative stress and thereby change the antioxidant defense system in the body. Supplementation of antioxidant vitamins might improve antioxidant status in the body. The purpose of this study was to evaluate the effectiveness of vitamin C supplementation and smoking cessation education on changes of antioxidant status and psychosocial factors related to smoking. To obtain above purposes, we investigated the effectiveness of intervention for male adolescent smokers were evalnate by assessing changes in dietary intakes, plasma antioxidant vitamin concentration, and psychosocial factors related to smoking after program completion. Subjects, male adolescent smokers, were assigned into four groups : Control group(19 students), Educ. group(19 students), Vit. C supple. group(19 students), and Educ.+Vit. C suppl. group(19 students). The Educ. group and Educ.+Vit. C suppl. group received nutrition and smoking cessation education once a week for 5 weeks. Vit. C suppl. group and Educ.+Vit. C suppl. group received 500 mg per day of ascorbic acid for 35 days. All data were collected before and after intervention. Vit. B$_2$and Vit. C intakes of all groups were increased, but the only Ca intake was increased in the Educ. group. Plasma Vit. C concentration and Ratio(plasma Vit. C/Vit. C intakes) were increased in the Vit. C suppl. group and Educ.+Vit. C suppl. group, and the Vit. C deficiency status of these groups(Vit. C suppl. group and Educ.+Vit. C suppl. group) disappeared. Showing the effects of Vit. C supplementation, plasma $\alpha$-tocopherol was increased in the Educ. and Educ.+Vit. C suppl. group, and especially high increases were seen in the Educ.+Vit. C suppl. group. Psychosocial factors related to smoking changed after the education a little. This intervention program had an impact on nutrition intakes, plasma antioxidant vitamins, and some beliefs related to smoking in male adolescent students. Various programs of nutrition and smoking cessation education and vitamin supplementation for quitting smoking must be implemented for adolescent smokers, and further studies are needed regarding sorts and amount of antioxidant nutrients and supplementation periods.

Background: Outcome-expectation beliefs and knowledge may ultimately influence behavior for cancer prevention. The aims of this study were to measure changes in knowledge and beliefs about cancer prevention before and after viewing a television advertisement and identify the factors affecting receptivity to its messages. Materials and Methods: A one-group pretest-posttest design was used in this study of 1,000 individuals aged 20 to 65 years who were recruited online in November 2014. The outcome variables included cancer prevention beliefs based on the Health Belief Model (five items) and knowledge about risk factors for cancer (seven items). Results: Perceived susceptibility, perceived benefits, and self-efficacy increased significantly and their perceived severity and perceived barriers decreased significantly, after participants viewed the television advertisement. Correct responses to questions about risk factors also increased significantly, except for smoking. The main factors affecting changes in the outcome variables were age, interest in cancer prevention, social network, satisfaction with the ad, and pretest scores. Conclusions: Television advertisements with positive frameworks can be an efficient channel of improving beliefs and knowledge about cancer prevention in a short period. The continuous development of intervention materials that consider the demographics, needs, and satisfaction of the target group will be necessary for future studies.

Objectives: Medical students represent a primary target for tobacco cessation training. This study assessed the prevalence of medical students' tobacco use, attitudes, clinical skills, and tobacco-related curricula in two countries, the US and Italy, with known baseline disparities in hopes of identifying potential corrective interventions. Methods: From September to December 2013, medical students enrolled at the University of Bologna and at Brown University were recruited via email to answer survey questions assessing the prevalence of medical students' tobacco use, attitudes and clinical skills related to patients' smoking, and elements of medical school curricula related to tobacco use. Results: Of the 449 medical students enrolled at Brown and the 1426 enrolled at Bologna, 174 Brown students (38.7%) and 527 Bologna students (36.9%) participated in this study. Italian students were more likely to smoke (29.5% vs. 6.1%; p<0.001) and less likely to receive smoking cessation training (9.4% vs. 80.3%; p<0.001) than their American counterparts, even though the majority of students in both countries desired smoking cessation training (98.6% at Brown, 85.4% at Bologna; p<0.001). Additionally, negative beliefs regarding tobacco usage, the absence of formal training in smoking cessation counseling, and a negative interest in receiving specific training on smoking cessation were associated with a higher risk of not investigating a patient's smoking status during a routine history and not offering tobacco cessation treatment to patients. Conclusions: Medical curricula on tobacco-related health hazards and on smoking cessation should be mandatory in order to reduce smoking among medical students, physicians, and patients, thereby improving tobacco-related global health.

Objectives: We describe the development of a smoking and drinking prevention program for adolescents, using intervention mapping. Methods: The study sample consisted of 1,000 high school second-grade students from 6 high schools in Seoul. The PRECEDE model was applied for the needs assessment. We carried out a social diagnosis by assessing the factors such as the quality of life, happiness level, and satisfaction with school life; an epidemiological diagnosis on the perceived health status, stress levels, and priority of health issues; a behavioral diagnosis on the smoking and drinking rate and the intention to smoke and drink; and an educational diagnosis on knowledge, beliefs, attitudes, self-efficacy, outcome expectations, social norms and life skills. Results: The development process included a needs assessment, identifying factors that influence smoking and drinking among adolescents. Intention, knowledge, perceived norms, perceived benefit, perceived cost, perceived susceptibility, self-efficacy, and life skills were identified as determinants. Three performance objectives were formulated to describe what an individual needs to do in order to avoid smoking and drinking. Subsequently, we constructed an intervention matrix by crossing the performance objectives with the selected determinants. Each cell describes the learning objectives of the smoking and drinking prevention program. The program used methods from the transtheoretical model, such as consciousness raising, outcome expectations, self-reevaluation, self-liberation, counterconditioning, environmental reevaluation, and stimulus control. The program deals with the effects of smoking and drinking, self-improvement, decision making, understanding advertisements, communication skills, social relationships, and assertiveness. Conclusions: By using the process of intervention mapping, the program developer was able to ensure a systematical incorporation of empirical and new data and theories to guide the intervention design. Programs targeting other health-related behavior and other methods or strategies can also be developed using this intervention mapping process.

The aim of this paper is to report the rate of current and ever cigarette smoking and explore correlates of current cigarette smoking among adolescents aged 13-15 in Viet Nam. This analysis was derived from GYTS survey, which comprised of 3,430 adolescents aged 13-15, conducted in 2014 in 13 cities and provinces of Viet Nam. We calculated the weighted rates of current and ever cigarette smoking and reported patterns of smoking behavior. We also performed logistic regression to explore correlates of current cigarette smoking behavior. The weighted rate of ever cigarette smoking was 9.5% (95% confidence interval (CI): 8.5 %-10.5%), in which the weighted rate among males (15.4%; 95% CI: 13.6%-17.0%) was higher than that among females (4.2%; 95% CI: 3.3%-5.1%). The weighted rate of current cigarette smoking was relatively low at 2.5% (95%CI: 2.0%-3.0%) with higher weighted rate among males (4.9%; 95% CI: 3.8%-5.9%) compared to the corresponding figure among females (0.2%; 95% CI: 0.0 %-0.5%). Current cigarette smoking was significantly higher among males than females, in students aged 15 versus 13 years old, and in students who had several or all close friends smoking and students with daily observation of smoking at school. For greater smoking reduction outcomes, we recommend that tobacco interventions for adolescents should consider targeting more male students at older ages, establish stricter adherence to school-based banning of cigarette smoking, engage both smoking and nonsmoking adolescents and empower adolescents to resist peer smoking influence as well as changing their norms or beliefs towards smoking benefits.

Background: Knowledge and individual perceptions about adverse effects of all forms of tobacco exert direct influence on the level of tobacco consumption in various socio-demographic groups. The objective of this study was to determine the nature, extent and demographic correlates of knowledge, attitudes and perceptions of use of tobacco among adults in low and middle income countries. Materials and Methods: The Global Adult Tobacco Survey, conducted in fourteen different countries from 2008-2010, was sourced for the data analyzed in this study. Descriptive statistical analyses were conducted to determine the prevalent knowledge and individual perceptions amongst adults about all forms of tobacco consumption. Results: There was relatively high awareness about the harmful effects of smoking tobacco with main awareness being about its relationship with lung cancer (>90% in most countries). In contrast, there was relatively low awareness about harmful effects of smokeless tobacco (< 90% in all countries except India and Bangladesh), and observed correlation of smoking tobacco with heart attack (40.6% in China, 65.1% in India) and stroke (28.2% in China, 50.5% in India). Conclusions: A large proportion of adults living in low and middle income countries possess adequate knowledge about smoking tobacco but have inadequate awareness as well as false perceptions about smokeless forms of tobacco. Popular beliefs of inverse relationships of tobacco consumption with knowledge, attitudes and perception of populations towards tobacco are challenged by the findings of this study.

This study compared levels of health and dietary behavior practices and health beliefs according to the stage of weight loss behavior change of Korean male workers. A self-administered survey questionnaire was collected from 411 male adult workers residing in Seoul, Kyeonggi, Chungcheong region. Practices of health related behavior, including smoking, drinking, exercise, work related physical activity, and dietary behavior according to dietary guidelines were evaluated. In addition, the levels of perceived benefit, perceived barrier, perceived susceptibility, perceived seriousness, and perceived cue to action from the health belief model were measured according to the stages of weight loss behavior change. Significant differences in BMI, level of daily exercise, and practices of dietary behavior according to dietary guidelines were observed among stages of weight loss behavior change. Subjects who were in action/maintenance stage showed a more desirable level of health behavior and health belief model variables, except perceived barrier. Based on the findings of this study, it is suggested that subjects with different stages of behavior change need an appropriate specific nutrition education method and material for improvement of nutrition education efficacy.

Purpose: The purpose of this study was to identify impacts of HPV-related knowledge, attitude to HPV vaccination, and health beliefs on infection preventive behavioral intention targeting female university students. Methods: With correlational survey design, subjects of this study were 120 female students at universities located in B metropolitan city and G city. A total sample agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, correlation, and stepwise multiple regression. Results: Attitude to HPV vaccination, experience of smoking, and HPV-related health beliefs were significant factors influencing the HPV-related infection preventive behavioral intention. These factors accounted for 19.0% of the HPV-related infection preventive behavioral intention. Conclusion: The most significant factor for HPV infection prevention was the attitude to HPV vaccination. These findings may be useful to develop strategies to improve the HPV infection preventive behavioral intention of the female university students who have a high risk of the HPV infection.
