Purpose: This study was done to identify predictors differentiating the preparation stage, which is the stage that the smoker is ready to quit smoking, between adolescent smokers and adult smokers. Method: A survey was conducted with 376 adolescent smokers in 4 high schools and 451 adult smokers in community settings in South Korea from August 2003 to April 2005. To identify the predictors before and after preparation in stages of change of smoking, logistic regression was done. Results: The predictors for before preparation in stages of change of smoking were process of change for smoking abstinence for adolescent smokers and depression for adult smokers. The predictors for after preparation in stages of change of smoking were self-efficacy for smoking abstinence for adolescent smoker and self-efficacy for smoking abstinence and smoking temptation for adult smokers. Conclusion: For each group, adolescent smokers and adult smokers, specific smoking intervention methods need to be developed based on the different ways individuals make the decision to quit smoking within their contexts.

Purpose: This study aimed to compare differences on sexual satisfaction between non-smokers and smokers of Korean adult males. Method: The subjects of this study were 304 current smokers and 331 current non-smokers(stop smokers, never smokers) (58.0%). Because of the nature of the study, the participants were recruited through a home page advertisement of a brand newspaper company in Korea, and the survey was done through Internet system. The tool to measure participant's sexual satisfaction was adopted from the Arizona Sexual Experience Scale-Male. Result: Participant's age ranged from 20 to 49, mostly in their 30s-40s(96.1%). They were smoking average of 15 cigarettes per day. There were no significant difference on sexual satisfaction between current smokers and non-smokers( t=-.55, p>.05). However, there were significant difference on sexual satisfaction between ever smokers(n=481) and never smokers(n=154) (t=2.10, p<.05). There were significant differences an erectile and orgasm satisfaction according to number of cigarettes they smoked per day. 54.5% smokers who said that they have difficulty in keeping erectile state considered on smoking cessation within 30 days whereas 24.2% in those who said that keeping erectile state was easy. Conclusion: Informing about the high risk of sexual dysfunction with cigarette smoking should become a important part of smoking cessation education and for smoking adolescents.

This study examines the effects of smoking on the health and nutrient intake of male adults. The subjects recruited are divided into two groups according to non-smokers (n=64), and smokers (n=50). The results show that the non-smokers are significantly more interested in health and maintain more frequency of weekly exercise as compared to the smokers. Smokers reported that the main reason for failures in quitting attempts was a lack of willingness (62.0%). 44.0% of smoker would be interested in attending a smoking cessation program if they had the opportunities to do so. The non-smoker is considered healthy, and ate a regular diet, and low in fat-rich foods compared to the smokers. The non-smokers and smokers consume lower intakes of vitamin $B_2$, folic acid, and calcium (Ca). On the other hand, intakes of phosphorus, and sodium are the highest among all groups. In the case of smokers, increased intakes of antioxidant-rich fruits and vegetables should be encouraged, and the nutrition education for low-salt-type foods is also recommended.

The purpose of this study was to investigate the nutritional status of serum minerals, ceruloplasmin, and ferroxidase activity in female adolescent students according to their smoking status. The subjects were 87 non-smokers and 88 smokers, who were female high school students. The smokers were divided into tow groups by smoking status, 35 light smokers(pack-year<1) and 53 smokers(pack-year$\geq$1). The serum concentrations of 6 minerals were determined by ICP emission spectroanalyzer. The serum concentration of ceruloplasmin and ceruloplasmin ferroxidase activity were determined. All data were statistically analyzed by SAS PC package program. The serum minerals concentrations of all subjects were in a normal range. There were significantly differences in the concentrations of serum copper, zinc, magnesium, and phosphorus by smoking status while there were no significant differences in the concentrations of serum iron and manganese by smoking status. Furthermore there were no significant differences in the ceruloplasmin concentration and ferroxidase activity by smoking status. In conclusion, smoking status altered the serum levels of some minerals in healthy young women. The minerals levels in light smokers with relatively short pack-year(pack-year<1) were altered compared to those in non-smokers or smokers. This finding seemed to be consistent with the results of previously published data related to antioxidant vitamin and lipid peroxide levels. However further research is needed to clarify these findings in female adolescent smokers.

Objectives: The purpose of this study was to investigate the smoking status among adult workers, and current status of sugar intake. Methods: The survey included 500 men working in Gyeonggi-do from October to November in 2016. Questionnaire items covered their age, working status, smoking status, eating habits, eating behaviors, snack consumption status, habits and behaviors related to sugar intake. All data were analyzed by SPSS program (Ver. 23) and descriptive statistics was performed; a t-test, ${\chi}^2$ test, One-way ANOVA and Scheffe test were used for post-hoc test. Results: The study results showed that eating habits and behaviors of non-smokers were better than those of smokers. The frequency of daily snack consumption was the highest in smokers compared to and non-smokers. The smokers' favorite taste after smoking was 'Sweet'. The average score of sugar-related nutrition knowledge was higher in non-smokers compared to smokers. Non-smokers had better recognition of 'sugar reduction', and smokers were more likely to eat sweet foods, respectively. On the other hand, non-smokers could observe that they were trying to control themselves for health reasons. According to the results of the study, non-smokers showed better eating habits and dietary habits and consumed less sugar. Also, it was found that non-smokers tried to drink more water than beverages and refrain from eating sweets to reduce their sugar intake. Further, the most of the bread, coffee and beverages were also consumed at a lower frequency by non-smokers compared to smokers. Conclusions: This study results showed that smoking and sugar consumption were closely related. Therefore, adult workers should actively promote and learn so that they can maintain healthy and suitable dietary habits through reduction of sugar consumption.

Objectives: The purpose of this study was to examine the effect of smoking on aerobic physical fitness among physical education major male university students participating in regular exercise. Methods: A group of 42 healthy male students majoring physical education were divided into two groups: non-smokers (n=$26, 20.61{\pm}2.78 $yrs) and smokers (n=16, $21.25{\pm}2.29 $ yrs). Graded exercise testing for maximal oxygen consumption ($VO_2max$) was measured by Bruce protocol. Results: $VO_2max$ was not different between non-smokers and smokers, however, exercise duration time in non-smokers was more longer than smokers'. In non-smokers, ventilatory threshold (VT) time was delayed longer than smokers (p<0.01). %VT/VEmax was significantly different between non-smokers and smokers (p<0.01). Resting heart rate (p<0.01) and recovery heart rate at 80 seconds (p<0.01) in non-smokers were significantly lower than those of smokers. The decrease in heart rate recovery in non smokers was greater than in smokers at 40(p<0.05), 60(p<0.05) and 80(p<0.01) seconds. Conclusions: These results suggest that smoking has negative effects on aerobic fitness of male university students in physical education major.

The aim of this study was to compare nutrient intakes, dietary habits, and blood components of smokers with non-smokers in the Seoul area and its vicinity. The results showed that non-smokers had higher intakes of brown rice, grains, fruit, vegetable and kimchi than the smokers. Smokers consumed more protein (p<0.001), vitamin B1 (p<0.001), vitamin B2 (p<0.007), niacin (p<0.0001), zinc (p<0.031) and phosphorus (p<0.005) than did non-smokers, whereas non-smokers' intakes of vitamin A (p<0.037), and folic acid (p<0.043) was higher than that of smokers. Individuals who smoked tended to have significantly higher levels of hemoglobin and monocytes. There were no significant differences by smoking status for dihydrolipoic acid (DHLA), arachidonic acid (AA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which were in normal ranges. No significant differences by smoking status were shown for plasma homocysteine, HDL-cholesterol, LDL-cholesterol, vitamin C, and vitamin A. In conclusion, because smokers maintain a less healthy diet and life-style, it is to be recommended that educational programs be developed for smokers, guiding them into adopting better dietary habits in order to maintain and improve their health.

The purpose of this study was to investigate of attitudinal beliefs regarding smoking, and antioxidant vitamins status between smokers and non-smokers in college male students. Attitudinal beliefs regarding smoking and antioxidant vitamins intake were investigated by a questionnaire. The result obtained were as follows: Anthropometric measurements were no significant differences between smokers and non-smokers. The attitudinal beliefs regarding smoking of smokers were different from those of non-smokers(p<0.001). Compared with non-smokers, smokers responded more positively on advantage of smoking, while they felt less negatively on disadvantage of smoking. Systolic blood pressure(SBP) and diatolic blood pressure(DBP) of smokers were significantly higher than those of non-smokers(p<0.05). Although antioxidant vitamins intake was not significantly different between smokers and non-smokers, plasma level of vitamin C of smokers was significantly lower than that of non-smokers(p<0.05). However, plasma level of vitamin E was not significantly different between smokers and non-smokers.

Objectives : The purpose of this study was to investigate the awareness towards oral health environmental changes and oral health in smokers and non-smokers in soldiers. Methods : Data were obtained from 350 soldiers serving at Unit M in Gwangju and Gyeonggi-do and ROTC candidates at University Y in Gyeonggi-do from April 28 to May 5, 2013. Collected data were analyzed by SPSS 12.0 program and a significant level was set at 0.05. Results : Non-smokers had more knowledge on tooth staining or gum diseases than smokers(p<0.05). The awareness towards the causes of oral cancer was not much different between the smokers and the non-smokers. The soldiers having dental health education tended to smoke less than those who had no education(p<0.05). The awareness towards individual oral health revealed no difference between the smokers and the non-smokers. Non-smokers had higher subjective knowledge on of the importance of the oral health, smoking influence on the oral health, and secondhand smoking impact on the health(p<0.05). Conclusions : The oral health education by the dental hygienists is very important in the military camps. Non-smokers tended to have higher knowledge on oral health than the non-smokers.

Cigarette smoking has long been recognized as a major risk factor in the development of coronary heart disease. Several investigators have reported the strong association between smoking and high serum cholesterol, triglyceride concentration, SFA and low HDL cholesterol, PUFA and $\omega$6 concentrations. Therefore, this study was done to investigate the effect of smoking on the serum lipid profile and fatty acid composition of college women. Sixty-one non-smokers and twenty-seven smokers were selected from college women students in the Seoul area. Their lipid intake, serum lipid concentration and fatty acid composition were examined. There were no differences in the general characteristics and anthropometric indices between the smokers and non-smokers. However, alcohol consumption was significantly higher in smokers than non-smokers (p<0.001). The daily caloric intake of smokers and non-smokers were 1875.84 kcal and 1915.53 kacl, respectively. On the other hand, the mean daily intake of lipids and cholesterol were significantly lower in smokers (p<0.05). In smokers, the mean concentrations of serum total cholesterol, LDL-cholesterol and the LDL-C/HDL-C ratio were higher, and the compositions of EPA and DHA were lowe than in non-smokers. There was a negative correlation between the serum triglyceride and PUFA levels in the two groups. Also, serum HDL-C correlated negatively with MUFA in smokers and non-smokers (p<0.01). These results suggest that smoking cause inadequate changes in serum lipid profile and serum fatty acid composition, thereby increasing the tendency for coronary heart disease.
