Objectives: The purpose of this study was to develop a prediction model for future smoking intention among Korean adolescents aged 13 to 15 in order to identify the high risk group exposed to future smoking. Methods: The data was collected from a total of 5940 students who participated in a self-administrated questionnaire of a cross-sectional school-based survey, the 2004 Korea Global Youth Tobacco Survey. Chi-square tests and logistic regression analyses were carried out to identify the relevant determinants associated with intentions of adolescents’ future smoking. Receiver Operation Characteristic (ROC) assessment was applied to evaluate the explanation level of the developed prediction model. Results: 8.4% of male and 7.2% of female participants show their intentions of future smoking. Among non-smoking adolescents; who have past smoking experience [odds ratio (OR) 2.73; 95% confidence interval (CI) 1.92- 3.88]; who have intentions of smoking when close friends offer a cigarette (OR 31.47; 95% CI = 21.50 - 46.05); and who have friends that are mostly smokers (OR 5.27; 95% CI = 2.85 - 9.74) are more likely to be smokers in the future. The prediction model developed from this study consists of five determinants; past smoking experience; parents smoking status; friends smoking status; ownership of a product with a cigarette brand logo; and intentions of smoking from close friends’ cigarette offer. The area under the ROC curve was 0.8744 (95% CI=0.85 - 0.90) for current non-smokers. Conclusions: For efficiency, school-based smoking prevention programs need to be designed to target the high risk group exposed to future smoking through the prediction model developed by the study, instead of implementing the programs for all the students.

Background: Tobacco use among youth is a major public health problem. Youth outside of formal school settings are often understudied but may be at increased risk. Materials and Methods: A descriptive cross-sectional study was carried out among 326 young people aged 15-24 years in four randomly selected motor parks in Lagos state. Interviewer-administered questionnaires were used to collect data. Results: The mean age of the respondents was $21.0{\pm}2.3yrs$. Many 252 (77.3%) dropped out before the end of the third year of secondary schooling. The majority were aware that active (78.2%), and passive smoking (77.3%) are harmful to health. Nearly two-thirds of the respondents disagreed with an outright ban of cigarettes (63.2%) and restriction of cigarette sales to persons below 18 years (67.9%) while 254 (66.8%) supported a ban on tobacco smoking in enclosed public places. One hundred and fifty (46.0%) respondents had experimented with smoking of which 106 (32.5%) had progressed to become current smokers. Half of the current smokers, 54 (50.9%), felt the need for a cigarette first thing in the morning. A multivariate analysis for smoking initiation, showed that for every increasing year of age, respondents were 1.08 times more likely to have initiated cigarette smoking; males and respondents who lived alone or with peers were 2.34 times and 1.77 times more likely to have initiated smoking respectively; those who consume alcohol and marijuana were 7.27 and 1.89 times respectively more likely to have initiated smoking while those who consumed alcohol were 6.17 times more likely to be current smokers.

The goal of this study is to identify and compare predictors of smoking initiation, persistence and smoking status among Hispanics and Whites. The sample includes 1,410 Hispanic and non-Hispanic White adults living in El Paso, TX, USA and Do$\tilde{n}$a Ana and Otero counties, NM, USA from the Paso del Norte 2002 BRFSS. Whites reported higher rates of cigarette smoking and became regular smokers earlier than Hispanics. Males were twice more likely to initiate cigarette smoking and progress to regular smoking than females among Hispanics, but this gender difference among Whites was not significant. Childhood exposure to drinkers or alcoholics was an important predictor of smoking initiation and becoming a regular smoker, but only among Hispanics. Few identified ethnic differences in predictors of smoking were found. The findings underscore the importance of Hispanic norms on smoking behaviors. Prevention efforts need to address the culture as one of the important components relevant to smoking.

In this study. we present a modified rational addiction model which incorporates social-psychological factors. This is done through a utility function which includes social-psychological factors as its component. We apply this model to a cigarette consumption function in Korea using the data from the Korean Household Panel Study(KHPS). The results provide relatively strong support for the rational addiction model. However. the impact of social-psychological factors and the short-run and long-run price elasticities are statistically insignificant.

Cigarette smoking has a negative effect for nutrient intakes and nutritional status of antioxidant nutrients including vitamin C. This study has been performed to compare the dietary nutrient intakes, serum vitamin C concentration and serum cotinine concentration of smoking teenage girls(n=104) with those of non-smoking teenage girls(n=791). The subjects were 895 high school girls(15-19 years of age) living in a rural community in Korea. Of the subjects, 11.6% stated that they were currently smoking. The frequency of taking alcohol, soda and coffee was higher in smokers than in non-smokers, respectively. The usage rate of vitamin/mineral supplements was higher in smokers than in non-smokers. The smokers tended to skip breakfast and lunch and to take snack more often than did the non-smokers. The dietary intakes of calorie, protein, vitamin A, vitamin B, vitamin C, calcium and iron were lower in smokers than in non-smokers. Daily mean intakes of these nutrients were less than the 2/3 of the Korean RDAs in smokers while these intakes were similar to or more than the RDAs in non-smokers. The ratio of under weight or lean tended to be higher in smokers. Serum vitamin C concentration was lower in smokers than in non-smokers. These findings show that smokers have unsound eating habits and poor nutirtional status. In particular, nutritional status of vitamin C is significantly poor in smokers, and this tendency can be found more notably in heavy smokers. Therefore, oxidative stress may be present in young teenage girls with short smoking history as evidence by above results. (Korean J Nutrition 34(3) : 338∼347, 2001)

Objectives: The purpose of this study was to investigate the factors contributing to intentions of quitting smoking, and use of smoking cessation services for daily smokers, and willingness of using smoking cessation services by the public health centers. Method: A total of 1,403 cases of male smokers were collected by a telephone survey. The age of smokers in the study ranged from 20 to 59. Socio-demographic variables, cigarette consumption behaviors, quit attempts and intentions of quitting smoking, and use of clinical services provided by the local public health centers were analysed using SPSS program. Result: About 77.8% of the smokers consumed a pack of cigarettes or less per day. About 20% of the smokers have used quit aides such as nicotine patch, gum, quit cigarettes, and acupuncture. These variables were associated with prior quit attempts in the past 1 year. Older age, degree of addiction(less time spent without smoking after a smoker gets up in the morning), prior quit attempts, panning to quit in one month, doctor's advice to quit were the major predictors of using the smoking cessation services provided by the public health centers. Conclusion: Health educators have to entice physicians to give smoking cessation advice to smokers, and have to provide many different types of educational programs to help quitting smoking.

Current studies indicated that emphysema in smokers might be due, in part, to the local suppression of G, -protease inhibitor(u, -Pl) in lung by reactive oxygen species in cigarette smoke or smoke-activated lung neutrophiles. In the present works, we examined the possibility that a measure which inactivated $\alpha$l-Pl by cigarette smoke could be an alternative method to evaluate the cigarette quality, In order to determine the inactivation of $\alpha$1, -Pl, trypsin inhibitory capacity(TIC) was assayed. A rapid loss of $\alpha$1, -Pl activity occurred when $\alpha$1-Pl solutions was exposed the gas phase or total particulate matter(TPM) obtained from various brands. The inactivation of $\alpha$1-Pl by gas phase was dependent upon the number of puffs and the age of the smoke. However, that by TPM was rather decreased since 2 puffs and also showed no more change over 24hrs after exposing. Inactivation of $\alpha$1-Pl determined by our suggested method(5 puffs, 24hours of aging after exposing) using various commercial cigarettes exhibited that high tar brands has inactivated it more strongly than low tar cigarettes. But the ability of some brands to inactivate $\alpha$1-Pl does not correlate with the content of tar or nicotine. These results so여esc that the degree of $\alpha$1-Pl inactivation by cigarette smoke may be a useful index for the evaluation of cigarette quality and that it should be also contribute to the manufacture of less hazardous cigarettes.

Purpose: The purpose of the study was to investigate the level of cigarette smoking and alcohol consumption in men with Diabetes Mellitus and to examine the relationships among those variables. Method: The subject consisted of 152 adult men with diabetes mellitus. Q-F methods and FTQ was used to measure the level of alcohol consumption and nicotine dependency. The amount of smoking was measured by the number of cigarette packs used per week. Results: Prevalence of drinking was 63.6% and in the current drinkers, 34.4% were heavy drinkers. The prevalence of cigarette smoking was 36.2% with a mean of 6.03 packs per week. Twenty percent of the smokers were dependent on nicotine. Subjects who had complications or other diseases drank alcohol more than who had not. There was a positive relationship between the level of smoking and nicotine dependency. Conclusion: Alcohol drinking and cigarette smoking is a serious health problem in men with diabetes. It is necessary to have an educational approach for controlling drinking and smoking in diabetes patients.

Background: For generations, cigarette smoking has presented an important public health concern. This study aimed to compare the health-promoting behavior, exercise capacity, physical activity level, health literacy, and knowledge level of smoking-related diseases between smokers and non-smokers. Methods: The study included 71 smokers (mean age, 32.69±8.55 years) and 72 non-smokers (mean age, 31.88±9.94 years) between the ages of 20 and 60 years. Assessments included a 6-minute walking test (6MWT), Godin Leisure-Time Physical Activity Questionnaire, Health-Promoting Lifestyle Profile II (HPLP-II), Cardiovascular Risk Factors Knowledge Level Scale (CARRF-KL), Asthma/COPD Awareness Questionnaire, the World Health Organization Quality of Life-Bref questionnaire (WHOQoL-Bref [TR]), and Health Literacy Questionnaire (HLQ). Results: The results from the study show that the number of coronary artery disease risk factors measured significantly higher among the smoker group members when compared to that of the non-smoker group members (p=0.001). Smokers had significantly lower %6MWT distance than non-smokers (84.83±4.72 and 93.45±7.16, respectively; p<0.05). However, there were no significant differences between the smokers and non-smokers in terms of physical activity, CARRF-KL, HLQ, WHOQoL-Bref, and HPLP-II subscales or total scores (p>0.05). Additionally, while only forty-one smokers (57.7%) were active, 48 of the non-smoker group was active (66.7%). Conclusion: Smokers suffer greater negative effects to their exercise capacity in comparison to non-smokers. Although smokers and non-smokers have similar levels of health literacy and similar levels of knowledge about cardiovascular disease risk factors and obstructive lung diseases, health professionals could continue to further increase individuals' awareness of smoking-related risk factors and continue to emphasize the importance of physical activity and exercise for protecting cardiopulmonary health.

This study was to compare arterial stiffness and hemodynamic responses between male smokers and non-smokers. This study also investigates the influences of smoking before exercise on arterial stiffness and hemodynamic responses. 24 male subjects of age 20-29 without history of cardiorespiratory disease were divided into smokers and non-smokers. Smokers had more than 5 years of smoking experience. In order to evaluate the effects of pre-exercise smoking, smokers were tested twice, once with a cigarette before the exercise and the other once without one. Data was collected from bio-impedance analysis, SphygmoCor XCEL, graded exercise test, and fitness test. Main results of this study are as follows: First, there are differences between smokers and non-smokers in cardiorespiratory and hemodynamic response functions, as shown by maximal oxygen consumption, exercise duration, and heart rate. Second, the although the arterial stiffness between smokers and non-smokers showed statistically significant differences in the speed of the pulse wave velocity and augmentation index, smoker had a faster rate. It shows that smoking behavior has a negative impact on the cardiovascular system. Third, pre-exercise smoking behavior does have an impact on cardiorespiratory and hemodynamic response functions, as shown by exercise duration and heart rate. Lastly, arterial stiffness between smokers and non-smokers showed statistically not significant in the speed of the pulse wave velocity and augmentation index. However, the difference was not statistically significant. Brachial systolic pressure, a component of pulse wave analysis, on the other hand, was significantly dependent on pre-exercise smoking behavior. Subjects who participated in this study are college students in early 20s. Given their relatively short history of smoking, it is possible that their smoking habits are not severe enough to develop into cardiorespiratory or cardiovascular diseases. But Smokers showed lower levels of cardiopulmonary functions, as maximal oxygen consumption and exercise duration than nonsmokers.
