Objectives: Students' life changes substantially as grade increases. It implies that risk factors that trigger students' smoking may not be consistent across grades. Most previous studies on student smoking have considered grade simply a control variable. This study examines which and to what extent risk factors are differently associated with smoking initiation according to grade level among high school students in Korea. Methods: Data from the Korean Youth Risk Behavior Web-based Survey (KYRBWS) conducted by the Korea Centers for Disease Control and Prevention (KCDC) in 2007 and 2008 were analyzed in this study. Results: Among boys, school location, school type and pocket money etc. significantly influence smoking initiation in the first grade than in any other grades, but the strength of the association decreased as grade increases except academic performance. Among girls, most independent variables were associated with smoking initiation in the second grade except school location, pocket money per week and academic performance. Conclusions: Our results suggested that the variables related smoking initiation in Korean high school students were notably different by grade and gender. These findings can serve as the basis of policy recommendations with regard to school efforts to prevent student smoking.

Purpose: The purpose of this study was to investigate factors influencing lifetime smoking and current smoking among adolescents in South Korea. Methods: Hierarchical logistic regression was conducted based on complex sample analysis using statistics from the 10th (2014) Korea Youth Risk Behavior Web-Based Survey. The study sample comprised 72,060 adolescents aged 12 to 18. Results: The significant factors influencing adolescent lifetime smoking were female gender, older age, higher stress, higher weekly allowance, lower economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. The significant factors influencing adolescent current smoking were female gender, older age, higher stress, higher weekly allowance, both higher and lower economic status compared to middle economic status, living apart from parents, parental smoking, sibling smoking, peer smoking, observation of school personnel smoking, and coed school compared to boys' school. Conclusion: Factors identified in this study need to be considered in programs directed at prevention of adolescent smoking and smoking cessation programs, as well as policies.

We investigate how smokers and drinkers have influenced on self-reported risk assessment and workplace injuries, using the Korean Working Conditions Survey. Our empirical results indicate that persistent smoking habit raises workers' job risk assessments and work injuries significantly. Also, former smokers notice relatively higher risk assessments in various work activities, but they are less likely to affect work injuries. More frequent drinking behavior leads to a positive effect of job risk perception and workplace injuries. Regular smoking with frequent drinking for high income classes, however, have significantly reduced the chance of work injuries. Furthermore, establishing smoking-designated area at the workplace makes workers reduce workplace accidents positively. Therefore, the network effect of smoking and drinking behaviors in private circle levels is suggested to extend into public and constructive activies at the workplace levels for sharing useful and productive information, which will eventually reduce workplace injuries dramatically.

Background and Purposes : Smoking is a well-known risk factor for ischemic stroke. It may contribute to s1Toke by inducing the aggregation of platelets and formation of atheroma, reducing cerebral blood flow, and increasing fibrinogen. However, the relative risk varies according to different ethnicity and area. Therefore, we performed this study to assess the risk of smoking for ischemic s1Toke in Korea. Methods : Cigarette smoking habit was studied in 308 patients with ischemic s1Toke and in 348 age- and sex-matched control subjects who had no history of stroke using case control methods. In multiple logistic regression analysis, smoking had a significant value of odds ratio adjusted for hypertension, diabetes mellitus, and hyperlipidemia. Results : The adjusted odds ratio (AOR) and 95％ confidence interval (CI) was significant in the medium smokers (AOR, 1.92; 95％ CI, 1.11 to 3.33: p< 0.05) and heavy smokers (AOR, 2.80; 95％ CI, 1.64 to 4.78: p< 0.05). Furthermore, the OR was higher in hypertensive subjects than in normotensive subjects compared to non-smokers (AOR, 1.98; 95％ CI, 1.01 to 3.85: p< 0.05). Conclusions : Our findings suggest that smoking is an independent risk factor for ischemic stroke in Korea.

Objective : In this study, we focused on estimating the burden of premature death in Korea caused by smoking using the YLL(years of life lost due to premature death) measurement. Methods : First, we determined parameters: such as age-specific standard life expectancy, age on death, sex, and cause of death by analyzing the national death certificate data and life table collected during 1997. These were provided by the National Statistical Office. Secondly, we estimated the age group- specific years of life lost due to premature death by employing the standard expected years of life lost(SEYLL) measurement. Thirdly, the burden of premature death caused by smoking was estimated using the YLLs measurement which was developed by the global burden of disease study group. Fourthly, We calculated the risk related to smoking using the population attributable risk. Results : The following results were obtained in this study: 1) Premature death that is attributable to smoking in males could be prevented in 60.9%(513,582 person-year) by non-smoking. 2) The burden of premature death by smoking for female was prevented to 17.7%(513,582 person-year) by non-smoking. Conclusion : We found that the YLL method employed in this study was appropriate in quantifying the burden of premature death. This provides a rational basis for planning a national health policy regarding premature deaths caused by smoking and other related risk factors.

Objective : To examine the relationship between cigarette smoking, alcohol and cancer mortality in men in the Kangwha cohort after 12 years and 10 months of follow up. Methods : The subjects consisted of 2,681 men in the Kangwha cohort aged over 55 in 1985. Number of deaths and the time to death front all cancers and other cause were measured and the data for the smoking and drinking habits were obtained from the baseline survey data in 1985. All subjects were categorized into four groups according to their smoking habits: non-smokers, ex-smokers, mode(ate-smokers (1-19 cigarettes per day), heavy-smokers ($\geq$20 cigarettes per day). In addition, they were also categorized according to their drinking habits: non-drinkers, light-drinkers ($\leq$1 drink per week), moderate-drinkers (<3 drinks per day), heavy-drinkers ($\geq$3 drinks per day). The cancer specific death rates were calculated according to their smoking and drinking status. The adjusted risk ratio for all cancer deaths according to their smoking and drinking status were estimated using the Cox's proportional hazard regression model. Results : Using nonsmokers as the reference category, the adjusted risk ratio for all cancer deaths were 1.573(95% CI=1.003-2.468) for heavy-smokers. For lung cancer deaths, the adjusted risk ratios were 3.540(95% CI=1.251-10.018) for moderate-smoker and 4.114(95% CI=1.275-13.271) for heavy-smokers. Compared to non-drinkers, the adjusted risk ratio for stomach cancer was 2.204(95% CI=1.114-4.361) for light-drinkers. Conclusion : Smoking is the most significant risk factor for cancer deaths particularly lung cancer.

Objectives: The aim of this study was to identify differential impacts on smoking and drinking behaviors according to early menarche. Methods: 31,277 Korean female adolescents who had undergone menarche were included. Among them, 1,822 participants(5.8%) who experienced menarche in elementary school under 4th grade were assigned to early menarche group and others were was assigned normal menarche group. Using 11th(2015) Korea Youth Risk Behavior Web-based Survey, logistic regression analysis was conducted. Results: Adjusted confounding variables were analyzed and it was found that both drinking and smoking behaviors were higher in early menarche group. The participants with early menarche showed higher risk of non-daily smoking(OR=1.39, 95%CI=1.18-1.63), light daily smoking(OR=1.64, 95%CI=1.14-2.35) and moderate-to-heavy daily smoking(OR=3.15, 95%CI=2.02-4.92). Also, in the drinking behaviors, the risk of light and heavy drinking was higher than those of normal menarche group. Conclusions: Finding of this study showed Early menarche adolescents were associated with heavy smoking and drinking behaviors compared to normal menarche. Further studies are needed more evaluations.

Objectives: The purpose of this study was to evaluate the association of smoking and drinking status with gingival symptoms among the adolescents in Korea. Methods:We used the data from the web-based survey of the National Korean Youth Risk Behavior of Korean Center for Disease Control in 2016. The study subjects were 65,528 adolescents from middle- and high schools. Data were analyzed by SPSS Ver. 19.0. Multiple regression analysis was used to assess the factors related to gingival symptoms. Results: We observed 1.52 of odds ratio (OR) for gingival symptoms for those who smoked only without drinking in middle schools. In addition, we had ORs of 1.29 or 1.69 for those who drank only without smoking, or who smoked and drank in the middle schools, respectively, compared to nonsmoking nondrinkers. Risk of gingival symptoms for those who drank only or who smoked and drank in high schools were 1.18 or 1.17 times higher than nonsmoking nondrinkers. Conclusions: Smoking and drinking status among the adolescents are the risk factors to develop gingival symptoms. The problem of smoking and drinking in the adolescents should be considered when establishing the policies and institutions to improve oral health targeting the adolescents.

Purpose: This study was conducted to evaluate the health behaviors and to find out risk factors of blood pressure of adult women in a rural area. Method: The convenient sample consisted of 159 adult women who lived in G-gun. The data was collected using a self-report questionnaire for health behaviors and mercury type sphygmomanometer for BP, between Jun I and August 15, 2003. Health behaviors measured smoking, alcohol, salt, lipid, stress, exercise, coffee, BMI and medication. To accomplish the goal of study, descriptive statistics, t-test, $x^2$-test, ANOVA and multiple regression analysis were. performed with SPSS 10.0. Results: The average age of subjects was 49.2(SD7.34)years old. The average SBP and DBP of subjects were 126.22mmHg(SDl6.73) and 8 1.25mmHg(SDl 0.31). There were significant differences in smoking(p=.000), cigarette consumption(p=.001), smoking duration(p=.000), BMI(p=.033), medication (p=.001), family history(p=.000) between normotensive and hypertensive. The main risk factors on SBP were medication, age, BMI, family history and smoking duration by 35.7% of the total variance these variables explained SBP. The main risk factors on DBP were BMI, education and medication by 17.60% of the total variance these variables explained DBP. Conclusion: These results suggest that health professional have to emphasize prevention of obesity, lasting medication and no smoking for prevention and management of hypertension in community health promotion program.

Purpose: This study was conducted to examine the prevalence of current smoking and the factors that influence current smoking among male high school students in Korea according to school type. Methods: Data were extracted from the Korea Youth Risk Behavior Web-Based Survey (2017) and multiple logistic regression was used based on complex sample analysis. The study sample comprised of 15,777 male high school students: 12,583 from general high schools (GHS) and 3,194 from specialized vocational high schools (SVHS). Results: The prevalence of current smoking was significantly higher in SVHS students (19.6%) compared to GHS students (12.6%). Low academic achievement, depressive symptoms, current drinking, and high household economic status were commonly associated with current smoking in male students from both school types. However, exposure to secondhand smoking at home, non-exposure to anti-smoking advertisement, exposure to tobacco advertisement, participation in smoking prevention or cessation education were related to current smoking in GHS students, while living in rural area was associated with current smoking in SVHS students. Conclusion: To reduce current smoking among male high school students, it is necessary to develop smoking prevention policies reflecting the factors associated with current smoking that are different by school type.
