Background: This descriptive and cross-sectional study aimed to investigate effects of cigarette smoking across three generations and perceptions of the smoking-cancer relationship on the cigarette smoking status of Turkish university students. Materials and Methods: The study sample comprised of 434 university students studying in different departments of a university. Data were collected using a socio-demographic data collection form and the Decisional Balance Scaleqand evaluated using the Mann-Whitney U test, CHAID and multiple regression analyses. Results: The average age of the students participating in the study is 19.6+.5.0, some 11.3% of the students reporting that they smoked cigarettes. No statistically significant relationship was ascertained between the cigarette smoking statuses of the students based on the cigarette smoking status of their grandparents (p=0.144). but there was alink to that of their parents (p=0.002). The difference between the cigarette smoking ratios of the students based on their perceptions of smoking-cancer relationship was statistically significant (p<0.001). Believing that there is a relationship between smoking and cancer decreased likelihood of cigarette smoking 3.7 fold. Cigarette smoking by grandparents, and believing that there is a relationship between smoking and cancer, and cigarette smoking by parents explained 8.3% of the cigarette smoking status of the students. Conclusions: While cigarette smoking by grandparents only indirectly influences cigarette smoking by the students, believing that there is a relationship between smoking and cancer, and cigarette smoking by parents are influential variables in determining cigarette smoking by Turkish students.

Purpose: This study examined whether there is a relationship between smoking and health behavior and the status of cigarette or e-cigarette smoking adolescents. Methods: This study, as secondary analysis research, used the raw data from the 14th Korea youth risk behavior survey 2018. The data were analyzed by frequency analysis, Rao-Scott 𝑥²-test, and logistic regression analysis. Results: Differences in gender, economic levels, and the educational levels of mothers were observed between cigarette smoking and e-cigarette smoking adolescents. The relationship between smoking and health behavior and status was examined by comparing cigarette and e-cigarette smoking. The results showed that the ratio of e-cigarettes was relatively higher in adolescents who have substance experiences. In contrast, cigarette smoking was related to drinking and perceived lack of sleep. Conclusion: This study suggests that it is necessary to develop healthy behavior that is strongly related to the smoking types of adolescents and health promotion programs.

Background: Electronic cigarette (e-cigarette) has rapidly increased. Even though e-cigarettes are actually not smoking cessation alternative supplies, some people perceive them as smoking cessation alternative supplies. The purpose of this study is to identify the relationship between e-cigarette experiences and smoking cessation behaviors among Korean adults. Methods: Cross-sectional data was collected from 7,550 participants of Korea National Health and Nutrition Examination Survey in 2014. A total of 867 participants who were current smokers were enrolled in this study. Multi-variable logistic regression analysis were performed to identify the relationship between the smoking cessation behavior and the e-cigarette experience. Results: The e-cigarette experience rate of current smokers was 22.1%. The e-cigarette experience rate was higher in groups with the higher income, the higher education level, and the white collar jobs. Smokers with experience of smoking cessation (odds ratio [OR], 3.03; 95% confidence interval [CI], 1.67 to 5.76) and with intention to smoking cessation in the future (OR, 1.59; 95% CI, 1.05 to 2.43) were more likely to experience the e-cigarette. Especially, smokers who used smoking cessation alternative supplies were more likely to experience the e-cigarette than smokers who did not use it (OR, 2.87; 95% CI, 1.59 to 5.18). Conclusion: We confirmed that e-cigarette experiences were associated with smoking cessation experience, smoking cessation plan, and use of smoking cessation aid among smokers in Korea. Additional studies should be continued to confirm whether e-cigarette are continuously influencing the smoking cessation of current smokers in South Korea as one of the smoking cessation alternative supplies.

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.

Objectives: The purpose of this study is to investigate the factors that affect the smoking type among those who have used regular cigarettes, liquid or cigarette-type e-cigarettes. Methods: The subjects of analysis were 6,081 people who had smoked regular cigarettes or e-cigarettes. For data analysis, SPSS ver.25.0 statistical package program was used. Multinomial logistic regression analysis was performed to find out the factors affecting smoking type. Results: Factors affecting the experience of using e-cigarettes compared to regular cigarette smoking are gender and class. Academic performance, living with family members, drinking experience, and secondhand smoke in school. The factors influencing dual use compared to regular cigarette smoking were gender, class, academic performance, economic status, living with family, drinking experience, and experience of secondhand smoke in school. Smoking cessation attempts had an effect on dual use compared to regular cigarette smoking. Conclusion: Smoking cessation experience had a greater effect on e-cigarette use than regular cigarette smoking.

Purpose: The purpose of this study was to investigate the intention of smoking cessation according to the level of cigarette price increase among adolescent smokers and to suggest a reasonable cigarette price to effectively reduce smoking prevalence. Methods: In 2007, subjects were selected from middle and high school students except twelfth graders using a complex sampling design which employs a two-stage cluster sampling method. In total, 1,001 current smokers were included in the study. To investigate the intention of smoking cessation according to the level of cigarette price increase, cumulative percentages of smoking cessation of every smoking-related subgroup were presented under the assumption that cigarette prices increased to 3,000, 4,000, 5,000, 6,000 or 10,000 won. Non-parametric statistical methods were used to compare the prices at which the subjects intended to quit smoking among the subgroups. Results: More than 50 percent of current smokers intended to quit smoking under the assumption that cigarette prices were doubled to 5,000 won. However, the effect of cigarette prices on smoking cessation was less sensitive when the prices exceeded 5,000 won. In addition, the median of cigarette prices at which the subjects intended to quit smoking was 5,000 won, excluding the subjects who smoked less than a cigarette a day. Conclusion: This study suggests that 5,000 won for one pack of cigarettes is a reasonable price to effectively encourage smoking cessation, considering the price elasticity. Therefore, this finding may be helpful in establishing a new cigarette price policy for anti-smoking.

Objectives: The purpose of this study is to provide basic data on the use of electronic cigarettes by identifying the relationship between smoking and smoking behavior and the use of electronic cigarettes. Methods: This study used data from 8,150 participants of the 'Korea National Health and Nutrition Examination Survey (KNHANES)' s 7th (2016). In this study, 1,051 people currently smoking were analyzed. The number of people using electronic cigarettes was 74 among current smokers. Results: The age of onset of smoking was 20.46 years old in the group not using electronic cigarette, and the age of starting smoking was 18.12 years old in the group using electronic cigarette(p<.001). In the education level, the current use of electronic cigarette was 1.82 times higher in high school graduates than college graduates(p<.005). The reason for using electronic cigarette was 4.32 times higher than other reasons for using electronic cigarette for the purpose of smoking cessation(p<.005). Conclusions: For the smoking cessation society, education for the electronic cigarette is needed from the adolescence and selective management for the people who use the electronic cigarette for the purpose of smoking cessation is needed.

Purpose: This study was conducted to investigate the effect of cigarette smoking on physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) and depression in patients with chronic low back pain. Methods: This study was a cross sectional study and subjects consisted of 60 young males with chronic low back pain. The subjects were allocated to two groups following a self-report survey: cigarette smoking group (n=25) or non-smoking group (n=35). Physical fitness (dominant hand grip power, dominant isokinetic leg muscle strength, abdominal muscle endurance, flexibility, cardiopulmonary endurance) were measured using objective methods and depression in patients with chronic low back pain was measured using the Korean version of center for epidemiologic studies depression (CES-D) scale. Results: The results of this study were as follows: In physical fitness, the cigarette smoking group showed a significant decrease in abdominal muscle endurance, flexibility, and cardiopulmonary endurance compared with the non-smoking group. Depression index (CES-D scale score) was significantly higher in the cigarette smoking group than in the non-smoking group. Conclusion: These results suggest that cigarette smoking had a negative effect on abdominal muscle endurance, flexibility, and cardiopulmonary endurance in patients with chronic low back pain. In addition, depression of patients with chronic low back pain was affected by cigarette smoking. Thus, we suggested that cigarette smoking may play a significant role in the deterioration of physical fitness and depression of chronic low back pain patients.

Objectives: Cigarette smoking prevalence among adolescent males in rural areas of Korea has increased in recent years. The aim of this study was to explore the factors related to increasing trends in cigarette smoking among adolescent males living in rural areas. Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey from 2006 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Multiple logistic regression models were used to explore the factors affecting cigarette smoking. We evaluated the linear time trends in the prevalence of factors that were related to current smoking status and the linear time trends in cigarette smoking in groups stratified by the exposure to each factor using logistic regression models. Finally, we examined the contributions of the factors to the time trends in cigarette smoking by adjusting for each of those factors in the baseline regression models and changes in the adjusted odds ratio by survey year. Results: A statistically significant increasing trend in smoking was observed after adjusting for the factors affecting cigarette smoking. Significant factors related to cigarette use were perceived stress, experience with depression, current alcohol drinking, exposure to secondhand smoke, and academic performance. The factor related to increasing trends in cigarette smoking was academic performance. Conclusions: Stress about academic performance is an important factor affecting the increase in cigarette smoking among adolescent males in a rural area of Korea.

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.
