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.

Background: Men and women who smoke tend to show less compliance to screening guidelines than non-smokers. However, a recent study in Korea showed that self-reported female smokers constituted less than half of cotinine-verified smokers. Therefore, the aim of this study was to identify hidden smokers using cotinine-verified method and examine cancer screening behavior according to biochemically verified smoking status. Materials and Methods: Among 5,584 women aged 30 years and older who participated in the Fourth and Fifth Korea National Health and Nutrition Examination Survey (KNHANES), 372 (6.66%) hidden smokers were identified based on interview responses and verified by urinary cotinine levels. We compared cancer-screening behavior (cervical, breast, stomach, and colon cancer) of female hidden smokers to that of non-smokers and selfreported smokers by cross-sectional analysis. Results: Hidden female smokers had significantly lower adherence to breast cancer screening compared to non-smokers (aOR (adjusted odds ratio) [95% CI] = 0.71 [0.51-0.98]). Adherence to stomach cancer (aOR [95% CI] = 0.75 [0.54-1.03]) and cervical cancer (aOR [95% CI] = 0.85 [0.66-1.10]) screening was also lower among hidden female smokers compared to non-smokers. Self-reported (current) smokers showed lowest adherence to cervical cancer (aOR: 0.64, 95% CI0.47-0.87), breast cancer (0.47 [0.32-0.68]), stomach cancer (0.66[0.46-0.95]), and colon cancer (0.62 [0.38-1.01]) screening compared to non-smokers, followed by female hidden smokers, then non-smokers. These lower adherence rates of current smokers were attenuated after we incorporated hidden smokers into the current smoker group. Conclusions: Cancer screening adherence of female hidden smokers was lower than cotinine-verified non-smokers but higher than current smokers. Considering the risk of smoking-related cancer among women, identifying hidden smokers is important to encourage appropriate cancer screening.

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 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.

Sister chromatid exchanges(SCE) in peripheral lymphocytes is recently used as a biomarker for increased cytogenetic damage in smokers. The purpose of the investigation was to determine if there were any relationships between dietary factors and their DNA damage as measured by SCE test in a group of 62 male cigarette smokers and 36 non-smokers. As expected, smokers as compared with non-smokers had high SCE levels (10.59$\pm$0.21 versus 9.23$\pm$0.17 SCE/lymphocytes ; p<0.05). No significant relationships were observed between SCEs and age in smokers and non-smokers. In smokers, SCEs were negatively correlated with egg frequency score(r=-0.336) and total food frequency scores(r=-0.283). In non-smokers, SCEs were positively correlated with white vegetable frequency score(r=0.333) and instant food frequency score(r=0.382). There was a positive association between SCEs and the history of coffee intake of smokers(r=0.318). SCE frequency was not influenced by any other dietary factors considered ; dietary diversity and quality scores, alcohol consumption, use of processed foods and intake of burned food. No significant relationships were found between SCEs and serum cholesterol or other hematological parameters of the subjects. These results indicate that increased egg frequency score, total food frequency score which reflects dietary quality, and decreased coffee intake may reduce cancer risk by preventing smoking-induced DNA damage as reflected by sister chromatid exchanges in human lymphocytes.

To investigate the relationship between eating behavior and the prevalence of adolescents drug abuse and smoking, this survey was conducted among 349 male students(mean age ; 16.0 $\pm$0.9yrs) at technical high schools in Kyunggi-Do. It was shown that 58.7% of total subjects were smoking and 11.2% were abusing drugs. Drug abusers weighed Less than non-abusers especially, student smokers were 2.7kg lighter than non-smokers despite the same height. Although parents' education showed no relationship with drug abuse, educational level of student smokers' fathers was significantly lower than that of non-smokers' fathers. Drug abusers and smokers showed significantly higher incidence of runaway from home, absence from school without notice, and parents' divorce than non-abusers and non-smokers. Drugs abused were sleeping pills(n=20), bonds and butane gas(n=9), marijuana(n=3), tranquilizer(n=3), morphine and cocaine(n=2), and pep pills like amphetamine(n=2) 76.9% of the drug abusers had their first experience in junior high school and 81% of the smokers stared smoking as early as in junior high school. Also, 44% of the smokers reported that they smoke daily. The drug abusers tended to have more irregular eating habits than the non-abusers. The smokers showed irregular mealtime, ate either too fast or too slow, and especially, often skipped lunch or dinner. The drug abusers and smokers took little vegetable in their meals and often ate bread or noodles instead of rice for staples. In addition, they preferred taste to nutrition when they had meals. The smokers tended to ingest smaller amount of calcium source such as milk or dinner food and fish with bone although they consume more volume of total foods than the non-smokers. All subjects took less in calorie, calcium, iron, vitamin A, vitamin E, riboflavin, and folic acid than the Recommended Dietary Allowance Those findings suggest that drug abuse and smoking cause bad eating habits that influence unbalanced nutritional state. Therefore, nutrition education should be provided to the adolescents so that they can recognize the disadvantages of drug and smoking and its relation to dietary relation.

The purpose of this study is to observe the relationship between smoking and control factors to blood pressure, such as sodium and potassium levels of dietary intake and serum in 67 rural university male students(smoker: 35 persons, non smoker: 32 persons). 3-day dietary record and blood sampling were conducted for measurements of the levels of dietary intake and serum. The results were as follows: 1) There are no significance between smokers and non-smokers in height, weight, and BMI. 2) Mean systolic and diastolic blood pressure of smokers and non-smokers were $131.33\pm93.75mmHg, \;119.37\pm80.62mmHg, $ respectively. Blood pressure of smoker was higher than that of non-smokers(p＜0.05). 3) There was no significant difference between smoker and non smoker in dietary potassium intake but dietary sodium intake and Na/K ratio of smoker were higher than those of non-smokers(p＜0.05, p＜0.05). And significant correlation was found between dietary sodium intake and blood pressure of smokers(p＜0.05). 4) Smokers of optimum gustation of salt(0.52%) was higher than that of non-smokers(0.49%). Even though blood pressure of smokers was not critical level, if they smoke continuosely until middle age, their blood pressure will be increased by smoking. The results of this study suggest that no smoking education program for smokers including the information about desirable food habits for prevention of hypertension should be developed.

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.

Background: Cigarette smoking is the major risk factor for development of lung cancer. Identification of effects of tobacco on airway gene expression may provide insight into the causes. This research aimed to compare gene expression of large airway epithelium cells in normal smokers (n=13) and non-smokers (n=9) in order to find genes which discriminate the two groups and assess cigarette smoking effects on large airway epithelium cells.Materials and Methods: Genes discriminating smokers from non-smokers were identified by applying a neural network clustering method, growing self-organizing maps (GSOM), to microarray data according to class discrimination scores. An index was computed based on differentiation between each mean of gene expression in the two groups. This clustering approach provided the possibility of comparing thousands of genes simultaneously. Results: The applied approach compared the mean of 7,129 genes in smokers and non-smokers simultaneously and classified the genes of large airway epithelium cells which had differently expressed in smokers comparing with non-smokers. Seven genes were identified which had the highest different expression in smokers compared with the non-smokers group: NQO1, H19, ALDH3A1, AKR1C1, ABHD2, GPX2 and ADH7. Most (NQO1, ALDH3A1, AKR1C1, H19 and GPX2) are known to be clinically notable in lung cancer studies. Furthermore, statistical discriminate analysis showed that these genes could classify samples in smokers and non-smokers correctly with 100% accuracy. With the performed GSOM map, other nodes with high average discriminate scores included genes with alterations strongly related to the lung cancer such as AKR1C3, CYP1B1, UCHL1 and AKR1B10. Conclusions: This clustering by comparing expression of thousands of genes at the same time revealed alteration in normal smokers. Most of the identified genes were strongly relevant to lung cancer in the existing literature. The genes may be utilized to identify smokers with increased risk for lung cancer. A large sample study is now recommended to determine relations between the genes ABHD2 and ADH7 and smoking.

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.
