In order to find smoking status and its related factors for female students, a survey was conducted for 1,045 female students of a women's university in Seoul from 22nd of May to 18th of June, 1995. The results were as follows: 1. Of the 1,045 respondents, 7.4% of them were current smokers and 20.6% of them were ex-smokers. The rate of smoking by the major field of study was 18.5% in art and physical education, 10.6% in liberal art and social science, 1.9% in natural science, and 1.2% in medical science. The rate of smoking by the grade was 4.1% in the freshman, 5.9% in the sophomore, 10.9% in the junior, and 10.0% in the senior grade. 2. 7.2% of respondents experienced first smoking at junior high school, 16.8% at senior high school, 4.1% after high school, and 69.2% at college. 3. The major motivation to start smoking was 'curiosity'(57.9%), 'releasing stress'(21.6%), and 'temptation from friend or senior'(12.0%). 4. The first smoking place was 'entertainment place'(49.6%), 'own room'(20.5%), and 'school '(11.3%). And the first smoking companion was 'friend'(62.3%), 'alone'(19.9%), and 'senior or junior'(5.1%). 5. The average quantity of a daily smoking was 6.16±5.29 cigarettes in current smokers and 31.2% of them had experience to quit smoking at least one or more time. 6. Most of the reasons to quit smoking in ex-smoker were due to 'bad taste '(60.5%), 'health concern'(27.4%) and 'religion'(2.3%). 7. Current smoker and ex-smoker had more positive attitude for the female smoking than nonsmoker. And 76.7% of nonsmokers answered that they would not smoke in the future. 8. Most correspondents(89.8% of nonsmoker, 83.7% of ex-smoker, 80.5% of current smoker) strongly supported the antismoking movement. 9. The major information source in smoking were from 'radio, TV'(51.0%), 'newspaper, magazine'(38.8%) and 'school'(7.7%). 10. The multiple logistic regression analysis showed that the related factors for smoking status were satisfaction of home life, coffee intake, alcohol drinking, sister's smoking, girl friend's smoking, and knowledge about smoking.

Objectives: This study measured the extent of local legislators' support for tobacco control policies and identified the predictors of that. Methods: Local legislators, from 21 Gu in Seoul Metropolitan City, underwent a self-administrated questionaire during the 6-week period from December 1, 2004 to January 15, 2005. Multiple linear regression model was used to assess relationships between five groups of variables(political factors including political ideology, personal characteristics, tobacco experiences, tobacco knowledge, contact with local health officers) and support for tobacco control policies based on an 11-item scale. Results: The rates of support for 'penalizing merchants who sell cigarettes to minors' and 'instituting a law mandating that parents should not smoke in a car when children are present' were highest as 87.5% and 82.0% respectively, and those for 'increasing price of cigarettes' and 'regulating stores that sell cigarettes' were lowest as 52.2% and 51.7% respectively. Support was higher among local legislators who thought government had a duty to promote healthy life styles, knew second-hand smoke could cause lung cancer, knew tobacco caused more deaths than alcohol. Support among ex-smokers and nonsmokers was higher than current smokers. Conclusions: The findings indicate that local legislators who oppose tobacco control measures may not be opposed to tobacco control per se, but are more generally opposed to a government role in health promotion, Thus, Tobacco control advocates need to be more attentive to the way tobacco control issues are framed for particular legislators. Further, they could work to increase tobacco knowledge among local legislators.

Objectives : To estimate the normal range of blood and urine cadmium levels using data from occupationally non-exposed office workers to cadmium in selected Korean women. Methods : A total of 437 women from healthy office workers were analyzed. To analyze blood and urine cadmium levels, blood and urine samples of study subjects were collected carefully and analyzed. Using a structured questionnaire, characteristics of the study subjects were investigated by well trained interviewers. Results : Mean blood cadmium concentration (CdB) was $0.46\;{\mu}g/{\ell}$ (GM; 0.16), whereas mean urine cadmium concentration (CdU) was $0.94\;{\mu}g/g$ creatinine (GM; 0.37). A significant increase of cadmium levels in blood and urine was observed by the rise of age (p=0.007; p=0.002, respectively). In the analysis of smoking state, blood and urine cadmium levels were higher in current smokers than in nonsmokers. In the multiple regression analysis, the rise of age and currently smoking were observed as a significant factor associated with cadmium level. Conclusion : These findings suggest that mean cadmium level in blood and urine indicated a relatively low level, although the rise of age and currently smoking were observed as a significant factor related to cadmium level. It can be used for the basic data to prevent harmful effects of cadmium exposure among female workers occupationally exposed to cadmium.

Purpose: This study aimed to assess the reference values and factors influencing blood lead levels among Korean adolescents. Methods: The study population consisted of 1,585 adolescents (801 males, 784 females; aged 10-19 years) who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed blood lead concentrations in relation to demographic/lifestyle characteristics for all participants. "Reference values" of blood lead levels were calculated as the upper limit of the 95% confidence interval of the 95th percentile. Results: The average "reference value" for blood lead concentrations among Korean adolescents was $2.25{\mu}g/dL$ ($2.49{\mu}g/dL$ for males, $2.07{\mu}g/dL$ for females), and the geometric mean of the blood lead concentrations was $1.34{\mu}g/dL$. Males had higher blood lead concentrations than females (male, $1.48{\mu}g/dL$; female, $1.19{\mu}g/dL$; P<0.001). Elementary school students had higher blood lead concentrations than junior and senior high school students ($1.44{\mu}g/dL$ vs. $1.31{\mu}g/dL$, P<0.001). Participants living in detached houses had higher blood lead concentrations than those living in apartments (P<0.001) and current smokers had higher concentrations than nonsmokers or participants with secondhand smoke exposure (P<0.05). Additionally, participants with excessive alcohol consumption had higher levels than non-drinkers (P<0.001). Conclusion: This study provides national reference data on blood lead concentrations stratified by demographic and lifestyle factors among Korean adolescents. Further studies are needed to elucidate the relationship between increased lead exposure and demographic factors including type of housing.

Cigarette smoking is a well known risk factor for cardiovascular disease and has negative effects on blood lipid and lipoprotein . Some of the associations between smoking and chronic disease can be attributed to the less healthful lifestyles of smokers. A large body of epidemiologic evidence suggests inverse relationships between ischemic heart disease and plasma vitamin C and E concentrations . Smokers have lower plasma concentrations of these vitamins than do nonsmokers. Smokers therefore need antioxidant vitamin supplementation. The purpose of this study was to investigate the effect vitamin supplementation on plasma lipid patterns in smoking college men. 24subjects were divided into 3 groups of which were the vitamin C supplementation group (n=8), the vitamin E supplementation group(n=8) and the vitamin C+E supplementation group(n=8). The vitamin C supplementation group consumed 500mg of ascorbic acid, the vitamin E supplementation group consumed 200IU of D-$\alpha$-tocopherol, and the vitamin C+E supplementation group consumed 500mg of ascorbic acid+ 200IU of D-$\alpha$-tocopherol for 4 weeks. We examined the plasma lipid patterns before and after the vitamins were supplemented. The results obtained were as follows ; In the vitamin C supplementation group, the concentration of total cholesterol decreased significantly and HDL-cholesterol increased significantly with the supplementation of vitamin. In the vitamin E and vitamin C+E supplementation groups, however, there were no significant differences observed with the supplementation of vitamin. Concentration of plasma LDL, triglyceride, free fatty acid were not significantly affected by the supplementation of vitamin in all groups. In terms of plasma fatty acid composition, the concentrations of saturated fatty acid were not significantly affected by the supplementation of vitamin in all groups. The concentrations of palmitoleic acid, arachidonic acid, and docosahexaenoic acid, however, significantly increased in the vitamin E supplementation group(p<0.05). The concentration of plasma linoleic acid significantly increased in the vitamin C+ E supplementation group)(p<0.05). The results of this study show that antioxidant vitamin supplementation in smokers has a tendency to decrease coronary heart disease risk in view of the plasma total cholestrol and HDL-cholesterol concentrations of the vitamin C supplementation group and fatty acid concentration of the vitamin E supplementation group.

Background: The cytokinesis-block micronucleus (CBMN) assay is a standard cytogenetic tool employed to evaluate chromosomal damage subsequent to pesticide exposure. Objectives: To evaluate the pooled levels of total micronuclei (MN) and binucleated cells with micronuclei (MNC) in 1000 binucleated lymphocytes among population occupationally exposed to pesticides and further determine the more sensitive biomarker of CBMN. Materials and Methods: A meta-analysis on the pooled levels of MN and MNC in binucleated lymphocytes among occupationally pesticide-exposed populations was conducted using STATA 10.0 software and Review Manager 5.0.24 in this study. Results: We found significant differences in frequencies of MN and MNC in 1000 binucleated lymphocytes between pesticide-exposed groups and controls, and the summary estimates of weighted mean difference were 6.82 [95% confidence interval (95% CI): 4.86-8.78] and 5.08 (95% CI: 2.93-7.23), respectively. However, when we conducted sensitivity analyses further, only the MN remained statistically different, but not the MNC, the summary estimates of weight mean difference were 2.86 (95% CI: 2.51-3.21) and 0.50 (95% CI: -0.16-1.17), respectively. We also observed pesticide-exposed subjects had significantly higher MN frequencies than controls among smokers and nonsmokers, male and female populations, and American, Asian and European countries in stratified analyses. Conclusions: The frequency of MN in peripheral blood lymphocytes might be a more sensitive indicator of early genetic effects than MNC using the CBMN assay for occupationally pesticide-exposed populations.

Background: Sister chromatid exchange (SCE) in human peripheral blood lymphocytes is one of the most extensively studied biomarkers employed to evaluate genetic damage subsequent to pesticide exposure. Objective: To estimate the pooled levels of SCE in human peripheral blood lymphocytes among population exposed to pesticide. Materials and Methods: Meta-analysis on the association between SCE frequency and pesticide exposure was performed with STATA 10.0 software package and Review Manager 5.0.24 in this study. Results: The overall means of SCE were 7.88 [95% confidence intervals (95%CI): 6.71-9.04] for exposure group and 6.05 (95%CI: 5.13-6.95) for controls, respectively. There was statistically significant difference in the SCE frequency in human peripheral blood lymphocytes between pesticide-exposed groups and control groups, and the summary estimate of weighted mean difference was 1.69 (95%CI: 1.01-2.38). We also observed that pesticide-exposed population had significantly higher SCE frequency than control groups among smokers, nonsmokers, pesticide applicator, pesticide producer, other exposure population and Asian population in stratified analyses. Conclusions: Data indicate that the SCE frequency in human peripheral blood lymphocytes might be an indicator of early genetic esffects for pesticide-exposed populations.

Because excessive consumption of sugar-sweetened beverages may reduce the quality of nutritional intake, this study examined the consumption patterns of commercial beverages, lifestyle, dietary habits, and perception of sweet taste. Participants were 407 male university students in Kyeooggido, Korea, and information was collected by self-administered questionnaire. Among them, 58 nonsmokers volunteered to participate in the taste test. Participants were divided into three groups according to the frequency of commercial beverage consumptions: 120 rare (< 1 serving/week), 227 moderate (1-3 servings/week) and 133 frequent (> 3 servings/week) consumption groups. More subjects from the rare consumption group chose water, tea, and soy milk, and more from the frequent consumption group chose carbonated soft drinks and coffee (P=0.031) as their favorite drinks. Frequent consumption group consumed fruit juice, coffee, and sports and carbonated soft drinks significantly more often (P=0.002, P=0.000, P=0.000, respectively), but not milk and tea. Frequent consumption group consumed beverages casually without a specific occasion (P=0.000) than rare consumption group. Frequent drinking of commercial beverages was associated with frequent snacking (P=0.002), meal skipping (P=0.006), eating out (P=0.003), eating delivered foods (P=0.000), processed foods (P=0.001), and sweets (P=0.002), and drinking alcoholic beverages (P=0.029). Frequent consumption group tended to have a higher threshold of sweet taste without reaching statistical significance. The results provide information for developing strategies for evidence-based nutrition education program focusing on reducing consumption of unnecessary sugar-sweetened commercial beverages.
