Purpose: We aimed to identify associations between the frequency of electronic cigarette (e-cigarette) use and smoking-related characteristics among adolescent smokers. Methods: We used data from the 14th Korea Youth Risk Behavior Survey. The participants were 3,722 smokers who had smoked cigarettes on at least one day during the past 30 days. The frequency of e-cigarette use was defined as the number of days that participants used e-cigarettes during the past 30 days, and was divided into four categories: 0, 1~2, 3~9, and ${\geq}10$ days. We used the $x^2$ test and multinomial logistic regression to examine the associations between the frequency of e-cigarette use and smoking-related characteristics. Results: Those who attempted to quit smoking, had used a heated tobacco product (HTP) at least once, or initiated e-cigarette use before middle school were more likely to use e-cigarettes for 3~9 days in the past 30 days. More frequent e-cigarette use (${\geq}10$ days) was associated with a higher frequency and greater amount of cigarette use, lifetime HTP use, and earlier initiation of e-cigarette use. Conclusion: Smoking-related characteristics differed by the frequency of e-cigarette use. Therefore, intervention programs targeting adolescent smokers should consider differences in smoking-related characteristics based on the frequency of e-cigarette use.

The purpose of this study was to investigate the association between adolescent smoking and antioxidant vitamins. Subjects were 87 non-smokers and 90 smokers. who were female high school students. Smokers were divided into tow groups by smoking status, 35 light smokers (packyear<1) and 53 heavy smokers(packyear$\geq$1). Dietary intakes were examined through questionnaires and nutrient intakes of vitamin C and A were analyzed by smoking status using Computer Aided Nutritional analysis program for professional (CAN-PRO). Serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and E were measured by HPLC. Erythrocyte lipid peroxide levels was measured by thiobarbituric acid reactive substance (TBARS) method. All data were statistically analyzed by SAS PC package program. The mean vitamin C intakes of non-smokers, light smokers and heavy smokers were 58.2mg/day, 50.1 mg/day 58.1mg/day, respectively. The mean vitamin A intakes of non-smokers, light and heavy smokers were 28.1$\mu\textrm{g}$R.E./day, 278.7$\mu\textrm{g}$R.E./day and 289.6$\mu\textrm{g}$R.E./day, respectively. There was no significant difference in dietary intakes of antioxidant vitamins by smoking status. However, the serum vitamin C level, 11.40mg/l in heavy smokers was 12% lower than that of than that of 12.70mg/l in non-smokers. The serum vitamin A level was not significantly different among the groups. Vitamin E level, 8.79mg/l in heavy smokers was 8% lower than that of 9.53mg/l in non-smokers. There was no significant correlation between the dietary intakes and serum levels of vitamin A and C. The erythrocyte TBARS level, 1.90nmol/ml in light smokers was significantly lower (p<0.05) than 2.71 nmol/ml in heavy smokers or non-smokers. The correlation data showed that the cerythrocyte TBARS level had a significant positive correlation with packyear. Overall results might suggest that cigarette smokers with a longer smoking history need more dietary intakes of vitamin C and E than do non-smokers to reach the same serum level.

Smoking can increase oxidative stress and thereby change the antioxidant defense system in the body. To investigate the relationship between male adolescent smoking and antioxidant status, we surveyed the eating habits and dietary intake of 82 smokers and 44 nonsmokers recruited from a male technical high school. In addition, antioxidant enzyme activity and lipid peroxide values were determined in both the plasma and the erythrocytes. Although the frequency of food intake was not significantly different, most nutrient intake was unexpectedly higher in smokers than in nonsmokers. In comparison with the Korean RDA, especially the average intake of Ca, Fe and vitamin $B_2$ didn t reach 75% of the Korean RDA in either smokers or nonsmokers. An analysis of antioxidant enzyme activity showed that plasma catalase. superoxide dismutase (SOD), glutathione peroxidase (GSH-px), erythrocyte catalase and GSH-px activities showed no significant difference between smokers and nonsmokers. However, the erythrocyte SOD activity of smokers (1.57 unit/mgHb) was significantly lower than that of nonsmokers (2.00 unit/mg Hb). In addition, the plasma ceruloplasmin concentration of smokers (28.68 mg/$d\ell$) was significantly higher than that of nonsmokers (26.30 mg/$d\ell$), whereas the specific ceruloplasmin ferroxidase activity of smokers (0.31 unit/mg) was lower than that of nonsmokers (0.35 unit/mg). The plasma and erythrocyte thlobarbituric acid reactive substance (TBARS) of smokers (2.57 $\mu$mol/L, 0.32 $\mu$mol/gHb) were also significantly higher than those of nonsmokers (2.25 $\mu$mol/L, 0.27 $\mu$mol/gHb). The overall data indicate that adolescent smoking might decrease the antioxidant capacity of the body, in part, by lowering the erythrocyte SOD activity and the specific ceruloplasmin ferroxidase activity.

The study purpose was to investigate psychosocial factors related to smoking among adolescent boys. The Theory of Planned Behavior provide the basis for the study. Twenty-five attitudinal beliefs, 9 normative beliefs and 20control beliefs were identified through questionnaire development. The data were analyzed using t-test and χ2-test. Thirty-three percent of 300 students were smokers. Most of the beliefs examined were significantly different between smokers(n=92) and nonsmokers(n=92). With respect to attitudinal beliefs, smokers responded less negatively on the items of bad health effects of smoking such as sore throat, headache, chest pain, risk of cancer and bad blood circulation(p<0.001), and decreased physical strength(p<0.05). Smokers believed less negatively on the items that smoking leads to bothering others, bad breath, yellow teeth and making them spend money(p<0.001). In contrast, smokers felt more positively on smoking as a means of stress management, relaxing, helping digestion(P<0.001). Smokers felt less pressure for not smoking from significant others. Especially mother, siblings, friends, girl friends, seniors of school were important sources of influence regarding subject's smoking. Smokers felt less confident in controlling the urge to smoke in several situations including; when they were with friends or asked to smoke by friends; after the meal, or drinking; when they were bored or stressed, upset, and when they felt unstable(p<0.001). Smokers also scored lower on specific skills to quit or control the urge to smoke as well as overall perceived control, compared to nonsmokers(p<0.001). These results suggest that interventions for adolescents incorporate diverse strategies to increase the perceived control over smoking in specific situations as well as overall perceived control, to help them realize and modify attitudinal beliefs, and to elicit support from significant others for not smoking.

This study was done to compare nutrient intakes, anthropometric indices, and psychosocial factors related to smoking by smoking status among adolescent girls in Seoul. Subjects were high school students, and smokers were 17.6%. Nutrient intakes were analyzed by convenient method, and anthropometric measurements were done by Inbody 2.0. Psychosocial factors of smoking were examined based on the Theory of Planned Behavior : 26 attitudinal, 9 normative, and 17 control beliefs were used. Smokers smoked 5-7 cigarettes a day on average, with 1.26 pack-years of smoking, There were no significant differences in anthropometric characteristics, except fat distribution, between smoking(n=92) and nonsmoking(n=92) and nonsmoking(n=94) group. The percentage of alcohol groups. Especially, caloric intake (63.6% of RDA) were much below the recommended level. With respect to psychosocial factors, 18 out of 26 attitudinal beliefs were significantly different between smokers and nonsmokers. Smokers responded less negatively on the items of bad health effects of relax(p<0.001). In addition, smokers were more convinced of advantages of smoking (test, etc.)but responded less negatively on the disadvantages of smoking(bothering others, yellow teeth, bad breath, etc.). Smokers expressed less pressure for not smoking from siblings, friends, school seniors than nonsmokers. In addition, smokers, expressed less confidence in controlling the urge to smoker or quitting smoking in several situations, such as 'after a meal', 'feel bored', 'with friends', 'when angry' offered a cigarette by friends', 'drinking coffee or tea', 'drinking alcohol', 'seeing others smoke'(p<0.001). Smokers also felt less developing in applying specific skills for controlling the urge to smoker or quitting smoking. These findings suggest the need for developing smoking cessation programs for adolescent females, focusing on specific beliefs identified in this study.

Purpose: This study investigated the rate of attempts to quit smoking and related factors in Korean adolescent smokers. Methods: The findings of this study were based on the data obtained from the '2015 $11^{th}$ Korea Youth Risk Behavior Web-based Survey'. The number of subjects was 5,123. Results: 71.7% of adolescent smokers in our study group had made previous attempts to quit smoking. Logistic regression analysis showed that the following significant factors were related to attempts to quit smoking: smoking amount (OR=1.78, 95% CI=1.42~2.23), experience of secondhand smoking in family (OR=1.16, 95% CI=1.02~1.32), experience of smoking cessation education in school (OR=2.05, 95% CI=1.79~2.35) anti-smoking publicity (OR=1.34, 95% CI=1.17~1.55), and close friend's smoking (OR=1.63, 95% CI=1.24~2.17). Conclusion: Smoking cessation policies and programs, especially those targeting adolescent smokers, should consider the factors mentioned above when designing new interventions or campaigns.

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.

Purpose: The prevalence of binge drinking has increased among Korean adolescents in recent years. The purpose of this study was to determine the influencing factors of adolescent binge drinking. Methods: This was a secondary analysis of data from the 14th Korea Youth Risk Behavior Survey. For the present analysis, 5,203 binge drinkers (girls who drank 3 or more glasses of soju and boys who drank 5 or more in average on one occasion in the last 30 days) and 4,464 non-binge drinkers were selected. Results: Compared with the adolescents who had no experience buying alcoholic beverages, the adolescents who responded that it was easy or uneasy to buy alcoholic drinks were more likely to be a binge drinker. Also, compared with never smokers, ex-smokers and current smokers were more likely to be a binge drinker. Binge drinking was positively associated with skipping breakfast, subjective health, and feelings of sadness or hopeless. Conclusion: The findings of this study may be useful in developing binge drinking prevention programs for adolescents.
