To investigate the relationship between eating behavior and the prevalence of adolescents drug abuse and smoking, this survey was conducted among 349 male students(mean age ; 16.0 $\pm$0.9yrs) at technical high schools in Kyunggi-Do. It was shown that 58.7% of total subjects were smoking and 11.2% were abusing drugs. Drug abusers weighed Less than non-abusers especially, student smokers were 2.7kg lighter than non-smokers despite the same height. Although parents' education showed no relationship with drug abuse, educational level of student smokers' fathers was significantly lower than that of non-smokers' fathers. Drug abusers and smokers showed significantly higher incidence of runaway from home, absence from school without notice, and parents' divorce than non-abusers and non-smokers. Drugs abused were sleeping pills(n=20), bonds and butane gas(n=9), marijuana(n=3), tranquilizer(n=3), morphine and cocaine(n=2), and pep pills like amphetamine(n=2) 76.9% of the drug abusers had their first experience in junior high school and 81% of the smokers stared smoking as early as in junior high school. Also, 44% of the smokers reported that they smoke daily. The drug abusers tended to have more irregular eating habits than the non-abusers. The smokers showed irregular mealtime, ate either too fast or too slow, and especially, often skipped lunch or dinner. The drug abusers and smokers took little vegetable in their meals and often ate bread or noodles instead of rice for staples. In addition, they preferred taste to nutrition when they had meals. The smokers tended to ingest smaller amount of calcium source such as milk or dinner food and fish with bone although they consume more volume of total foods than the non-smokers. All subjects took less in calorie, calcium, iron, vitamin A, vitamin E, riboflavin, and folic acid than the Recommended Dietary Allowance Those findings suggest that drug abuse and smoking cause bad eating habits that influence unbalanced nutritional state. Therefore, nutrition education should be provided to the adolescents so that they can recognize the disadvantages of drug and smoking and its relation to dietary relation.

Tobacco smoke was confirmed as a human carcinogen by many research results. Because many adolescents stay long time in the PC game room, they are exposed to much of tobacco smoke. To evaluate the effect of passive smoking in the PC game room, airborne nicotine concentrations in 2 PC game rooms in Sung-nam city and urinary cotinine concentrations were measured for 20 adolescents. And the subjects were interviewed for duration and time in PC game room and smoking pattern. Subjects are composed of each of 10 smokers(5 males and 5 females) and 10 nonsmokers(5 males and 5 females). They stayed for three hours in the PC game room without smoking. Concentrations of nicotine in smokers and nonsmokers were 129.72 $\mu$g/$^3$ and 99.99 $\mu$g/m$^3$, respectively. Urinary cotinine concentrations were increased as time goes on after exposure to nicotine and showed maximum value at 9.45 hours after nicotine exposure and were 32.21 and 110.66 $\mu$g/L for nonsmoker and smokers. The more using time and frequency in PC game room, the higher urinary cotinine maximum concentration and the longer using duration, also the more increase urinary cotinine concentration. Urinary cotinine has a tendency to increase by passive smoking. Therefore, it is recommended that the effective control for indoor air quality and extensive research be needed to reduce nicotine concentration by passive smoking in the PC game room.

Purpose: The purpose of this study was to describe stage distribution of current and former smokers and to analyze significant variables that used by adolescents at each stage using the Transtheoretical Model. Methods: A cross-sectional study was performed with 145 students attended to five high schools in one rural area. The survey instruments included stages and processes of change. decisional balance, self-efficacy, and knowledge related to smoking. Results: Among the participants, 47.6% were in the precontemplation and contemplation stages, 20.7% were in the preparation stage, and the other 31.7% were in the action and maintenance stages. Analysis of variance tests revealed that behavioral processes, pros and cons of smoking, and self-efficacy were significantly associated with the stages of smoking cessation, while among 10 processes of change, self-reevaluation, self-liberation, and reinforcement management were significantly different by the stages. Conclusions: The study results suggest that smoking cessation programs should emphasize behavioral strategies, self-efficacy, and decisional balance to help students adopt and maintain smoking cessation.

Objectives: This study aimed to provide foundational data for preventing adolescents smoking by analyzing the relationship between adolescents' lifestyles and smoking experiences and identifying influencing factors. Methods: Secondary data analysis was conducted using the 17th (2021) Youth Health Behavior Survey data, encompassing 54,848 students from 796 schools. Variables included general characteristics, smoking status, lifestyle habits, physical activity, sleep patterns, and stress perception. Frequency analysis was used to examine general characteristics, while further analysis employed frequency analysis and the Pearson Chi-square test to compare lifestyle differences based on smoking presence. Multinomial logistic regression analysis was employed to determine factors influencing smoking experience, with IBM SPSS Statistics 28 used for all analyses at a significance level of p<.05. Results: Analysis revealed with general characteristics that the group with smoking experience exhibited a higher proportion of male students (67.4%) compared to the non-smoking group (50.1%) (p<.001). Analysis revealed that the smoking group was more likely to skip breakfast (27.7%), not consume fruit (17.8%), and consume fast food more than three times daily (0.9%). Furthermore, a higher percentage of smokers engaged in 60 minutes or more of breathless physical activity (8.4%) seven times a week, reported insufficient fatigue recovery through sleep (21.6%), and experienced very severe normal stress (17.2%) (p<.001). Analysis of the relationship between lifestyle and smoking indicated increased likelihood of smoking with zero breakfast consumption (OR=1.759, p<.001) and increased fruit consumption (OR=1.921, p<.001), while zero fast food consumption decreased smoking likelihood (OR=0.206, p<.001). Adequate sleep-related fatigue recovery reduced smoking likelihood (OR=0.458, p<.001), whereas increased stress elevated it (OR=1.260, p<.05). Conclusion: Adolescents' lifestyle habits significantly correlated with their smoking experiences, highlighting the necessity of considering lifestyle factors in smoking prevention strategies. This study provides crucial insights for promoting healthy lifestyle changes to prevent smoking among youth.

Objectives: This study was conducted to find out health behaviors and health promotion behaviors and their influencing factors among North Korean refugee adolescents. Methods: All the 139 students registered in a specialization school which provided regular school curriculum for the North Korean refugee adolescents participated in the survey. Collected data were analyzed by descriptive statistics, t-test, ANOVA, and multiple regression analysis. Results: Current smoking, alcohol drinking and experience of depression in North Korean refugee adolescents were more prevalent than those of South Korean adolescents. Self-esteem, self-efficacy and social support were identified as factors affecting health promotion behavior. Conclusions: Health promotion program is needed to reduce the North Korean refugee adolescents' depression and to stop smoking and drinking. In the process of creating these programs, of creating program, we should consider self-esteem, self-efficacy and social support in the educational method to make these programs be effective.

Objectives : Cotinine, the major metabolite of nicotine, is a useful marker of exposure to tobacco smoke and self-reporting of smoking status is thought not to be reliable. This study aimed to evaluate the agreement between the smoking self-report among adolescents and the urinary cotinine test. Methods : The study subjects were 1226 middle and high school students in Hanam city, who were selected by stratified random sampling. The self-report about smoking behavior was compared with urine cotinine value measured with PBM $AccuSign^{\circledR}fi$ Nicotine(Princeton BioMeditech Corporation, USA). The percentage agreement, kappa and 95% confidence interval(CI) were calculated. Results : The overall percentage agreement was 88.6%, and those for boys, girls, middle school, general school and vocational school students were 87.3%, 90.1%, 93.7%, 85,5%, 90.7%, and 78.4%, respectively. The overall kappa index was 0.46(95% CI=0.39-0.54)for overall, .and those for boys, girls, middle school, general school and vocational school students were 0.56(95% CI=0.48-0.65), 0.20(95% CI=0.07-0.32), 0.21(95% CI=0.09-0.34), 0.55(95% CI=0.47-0.64), 0.42(95% CI=0.33-0.52), and 0.48(95% CI=0.36-0.60), respectively. Conclusion : The percentage agreement was relatively high but the kappa values very low for girls, and middle school students. Though the prevalence bias can be influenced by these results, the self-report was not a sufficient tool for the evaluation of adolescents' smoking status, especially in girls or middle school students.

Purpose. The purpose of this study was to test the effectiveness of a comprehensive smoking cessation program for Korean adolescents. Method. The study design was quasi-experimental with one pre and three post-tests. The three posttests were done immediately after, three months later, and six months after the completion of the program. A total of 43 high school students who smoked participated in the study with 22 in the experimental group and 21 in the control group. The smoking cessation program consisted of 9 sessions with content on enhancement of self-efficacy, stress management, correction of distorted thoughts, consciousness raising, and assertiveness training. The study variables were urine cotinine levels, self-efficacy, stress, and stages of changed behavior. Results. Urine cotinine levels significantly decreased in the experimental group after the program (F=3.02, p=.06) but significantly increased in the control group (F=6.32, p=.004). Self-efficacy and the degree of stress did not change in either group. The stages of smoking cessation behavior tended to change when compared with raw data for the experimental group. For most participants, the stages of change had been precontemplation and contemplation, but changed to action and maintenance stage among the experimental group. Conclusion. The program was effective in smoking cessation and influencing stages of change but did not change psychosocial factors such as self-efficacy and stress. It is suggested a program should be developed to change psychosocial variables on a long-term basis. It is also desirable to involve peers and families of adolescents who smoke when planning programs to enhance social support.

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.

Purpose. The purpose of this study was to identify the stage of change of smoking cessation behavior and investigate factors associated with the stage of smoking cessation behavior according to the transtheoretical model. Methods. The participants, 297 smokers & quitters were selected by a stratified random sampling from 127 high school sophomore students in B city. Data were collected from April 6th to 16th, in 2002 using the structured self-report questionnaire. Results. The subjects were distributed in each stage of change of smoking cessation behavior: there were 46 subjects (15.5%) in precontemplation, 73 subjects (24.6%) in contemplation, 67 subjects(22.3%) in preparation, 56 subjects (18.5%) in action, 55 subjects (18.5%) in maintenance. Compared to the precontemplation and contemplation, people in preparation tended to smoke daily more and smoked for a shorter time, and as precontemplation progressed to the maintenance, past 1 year smoking cessation frequency increased and friends smoking decreased. Smoking onset age was the earliest in preparation, and the latest in maintenance. Helping relationships and self relationships are used a lot in precontemplation and also in contemplation. In preparation, self liberation and helping relationships are used a lot, in action, self liberation and helping relationships, and in maintenance, self liberation and environmental reevaluation. At each stage, the score of negative affect situation was the highest, but the one of negative affect situation, positive social situation, habitual strength, weight control decreased as precontemplation progressed to the maintenance. While the score of social pros and coping pros decreased with increasing stage, the one of cons tended to increase. Through stepwise discriminant analysis, it was found that social pros, smoking onset age, delf-libration were the most influencing powers among factors associated with the stages of smoking cessation behavior. Conclusions. This study suggested that, in developing an effective smoking cessation intervention for adolescents, all the stage of a client's cessation had to be assessed prior to applying intervention programs. In addition, the results of this study will become a pillar of smoking cessation program planning and application.

This study aims to investigate smoking patterns in high school student and to give student smoker effective information. The sample of 250 male highschool students out of two different schools in Tae-Jon was questioned from July 10th to 15th. 1995. In analyzing these date. the statistics shows the realities by means of number of students. The results are summarized into 17 items as follows. Regarding the level of smoking. 140 students out of 250 admit that they have ever smoked. 52.1% of smoking students say that the motivation of beginning smoking is mainly curiosity. The survey shows that 22.9% of smoking students feel very good when smoking. It also shows that 30.0% of smoking students began smoking in the first grade of high school. With regard to the volume of smoking per day. 41.4% of smoking students smoke variably. 42.1% drink when smoking. 15.0% spend more than W 70.000 a month. About the question who knows the fact of their smoking. 51.5% answer that their friends know the fact of their smoking. In regard to the resaltionship between smoking and school per-formance. 18.2% of non smoking students make poor grades as compared with 40% of smoking students. 9.3% of smoking students say that they are satisfied with the school life. but 35.7% of them are not satisfied. Regarding the attitude to smoking teachers. 35% of smoking students state that they are affected by them. 69.3% of smoking students say that they will stop smoking. while the remaining 30.7% say that they will keep smoking. The reason of 63.9% to stop smoking is that smoking is bad for the health. The reason of 46. 5% to keep smoking is the acquired habit of smoking. 97.2% know the fact that the major element of cigarettes is nicotine and it is very harmful to the health. 40.8% recognize the harmful effect of smoking by TV and radio programs. 97.2% know that smoking could cause lung cancer. From the above results. I propose as follows We should make specific plan to keep smoking by simple curiosity from being developed into habitual smoking. We should teach them how harmful smoking is and make them stop smoking by themselves. It is very essential for family members and teachers to give continuous interest since childhood. As the teacher affect the students very much, they should give up smoking first. The incidence of smoking should be identified in each of the middle and high schools. smoking prohibition programs relevant to each school should be developed and implemented. The local community should ban cigarette vending machines. Cigarettes should not be sold to adolescents. By setting every place where adolescents gather including schools nonsmoking area. we should decrease their impulse to smoke. then smoking opportunities. and harmful effects to them caused by passive smoking.
