This study examined the cultural dietary habits as well as attitudes toward food, within other life pattern elements, of students living in Gwangju City and Chonnam Province, Korea. Questionnaires from 1,000 student respondents were analyzed. The survey consisted of questions regarding physical condition and health status, dietary consciousness, food preference, knowledge of food and nutrition, and dietary culture. The results showed that 1.6% of the students considered their own physical condition to be extremely poor, and 2.7% and 2.1% also considered their father's and mother's physical conditions as extremely poor, respectively. Among the respondents, 18.3% were smokers and consumed an average of 14.8 cigarettes per day. With regard to their dietary habits, the students answered that they preferred to eat meals with friends rather than with family members, fruit was chosen for eating over health food supplements, and there was very little participation or interest in various food and cultural festivals. The female students had a tendency to alleviate mental stresses by eating, while the male students performed more physical activity to deal with stress. The female students also preferred cereal, fruit, fast food, and sweetened foods more than the male students. Between the smokers and non-smokers, significantly more non-smokers chose fruit (p<0.01), ethnic foods (p<0.05), and sweetened foods (p<0.05) as compared to the smokers. Body mass index (BMI) had significant positive correlations with soft drink (p<0.01), health food supplement (p<0.01), and alcoholic beverage (p<0.001) consumption, while BMI was negatively correlated with cereal (p<0.01), fruit (p<0.001), and sweetened food (p<0.01) intake. The health status of students was positively correlated with their father's health status (p<0.01), mother's health status (p<0.001), and BMI (p<0.05), as well as cereal (p<0.001), high protein side dish (p<0.01), fruit (p<0.01), vegetable (p<0.01), and traditional food (p<0.001) intake. The average body weight for female students was approximately 5 kg less than the Korean Nutrition Society's standardized weight, therefore, it is strongly recommended that measures be taken to develop a systematic nutrition education program that would help those students who often unintentionally skip breakfast or go on extreme diets to improve body image.

Background: It is well known that smoking is a preventable factor for all-cause mortality; however, it is still questionable how many years after smoking cessation that people will have reduced risk for mortality, in particular in those with a high interest in their own health. We aimed to examine the association between time since quitting smoking and total mortality among past-smokers relative to current smokers. Materials and Methods: We enrolled 36,446 health examinees that voluntarily taken with diverse health check-up packages of high cost burden in 1995-2003 and followed them till death by 2004. The history of cigarette smoking consumption was collected using a self-administrative questionnaire at the first visit time. Mortality risk by smoking cessation years was analyzed using Cox's proportional hazard model. Results: Compared to non-smokers, male smokers over 15 pack-years had higher risk for total mortality (HR=1.60, 95%CI 1.23-2.14). The mortality risk in female smokers with same pack-years was more pronounced than that in male smokers (HR=2.83, 95%CI 1.17-7.04) despite a small number of cases. Compared to current smokers, a decrease of total mortality was observed among those who ceased smoking, and inverse dose-response was found with years after cessation: RR 0.98 (95%CI, 0.64-1.41) (<2 yrs), 0.60 (95%CI, 0.43-0.83) (3-9 yrs), and 0.58 (95%CI, 0.43-0.79) (${\geq}10$ yrs). Conclusions: A reduced risk of total mortality was observed after 3 years of smoking cessation. Our findings suggest that at least 3 years of smoking cessation may contribute to reduce premature mortality among Asian men.

Purpose: The purpose of this study was to identify the effectiveness of public health center smoking cessation counseling program using the transtheoretical model on the process of change, smoking temptation, decisional balance and stage change transition. Methods: A nonequivalent control group non-synchronized design was used for this study. The study population was 115 adult smokers. The counseling program was administered to the experimental group and a smoking cessation program from the Korean Ministry of Health & Welfare was administered to the control group. Descriptive analysis, $\chi^2-test$, t-test, and ANCOVA were used with the SPSS 12.0 program to analyze the data. Results: After treatment with this program, the experimental group showed significantly higher scores for process of change (t=4.148, p<.001), smoking temptation (t=-2.988, p=.003), and stage change transition ($\chi^2=5.871$, p=.031) compared to the control group. Experimental group members also showed significantly lower score for Pros of smoking (t=-3.151, p=.002). Conclusion: The findings indicate that this program could have positive effect on process of change, smoking temptation, decisional balance and stage transition for adult smokers. Based on these findings, the authors suggest additional counseling program focusing on smokers in specific stages.

Background: In this case-control study, we aimed to investigate the relationship between the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and lung cancer. Materials and Methods: Total 200 individuals including 100 patients with lung cancer and 100 controls were analyzed. Genotyping of MTHFR C677T was performed using PCR and RFLP methods. Results: The majority of the patients were men and 90% were smokers. We found that the risk ratio for development of LC was 13-times higher in smokers compared with non-smokers between patient and control groups in our study (OR:13.5, 95%CI:6.27-29.04, p:0.0001). Besides, the risk ratio for development of LC was nine times higher in individuals with cancer history in their family than those without cancer history (OR:9.65, 95%CI: 2.79-33.36; p:0.0001). When genotype distributions and allele frequencies were analyzed in the study groups, no significant difference was apparent (${\chi}^2$:0.53, p=0.76). In addition, no correlation between genotypes of MTHFRC677T polymorphism and histological type of LC was found (${\chi}^2$:0.99, p=0.60). Conclusions: These results suggest that there was no association between the MTHFR C677T polymorphism and lung cancer in the Turkish population.

Background: The influence of smoking on nonsyndromic clefts has been a topic of research for many years. However, few studies have investigated the effect of smoking on causing clefts in different gene pools. Methods: A meta-analysis was conducted of case-control studies related to smoking. Keywords such as "clefts," "cleft lip," "cleft palate," "orofacial cleft," and "smoking" were used to search the MEDLINE, Embase, and Cochrane databases. Results: In total, 51 articles were reviewed. The RevMan software was utilized for the analysis, and the Mantel-Haenszel method was employed to pool the odds ratios (ORs) and 95% confidence intervals. Although the overall OR, a measure of the association between exposure and outcome, was higher for smokers than for non-smokers, this association was significantly stronger in individuals from Asia and South America (1.73), and lowest in Europe (1.31). Among active and passive smokers in Asia, the OR was approximately 0.93, indicating an equivalent impact from both types of smoking. Conclusion: This analysis indirectly suggests that restriction measures targeting both active and passive smoking are crucial in Asia.

목적 정상으로 보이는 chest CT를 정량화 분석하여 흡연 및 폐쇄성 폐질환(chronic obstructive pulmonary disease; 이하 COPD) 여부에 따른 차이가 있는지 확인하고자 하였다. 대상과 방법 2013년 1월부터 2014년 12월까지 chest CT가 정상이면서 정량화 분석이 있는 90명의 남자 환자[COPD 없는 비흡연자(n = 38)와 흡연자(n = 45), COPD 흡연자(n = 7)]를 대상으로 하였다. COPD 흡연자 7명을 대상으로 나이를 추출하여 환자-대조군 연구도 하위 분석하였다. Pi10, 왜도, 첨도, 평균감쇠계수, 저감쇠영역%와 같은 정령화 변수를 분석하였다. 결과 COPD가 없는 환자 중에서 흡연자의 Pi10 (4.176 ± 0.282, n = 45)이 비흡연자에 비해 약 0.1 mm 정도 두꺼웠고(4.070 ± 0.191, n = 38, p = 0.047), 흡연자의 왜도와 첨도(2.628 ± 0.484 and 6.448 ± 3.427)가 비흡연자보다 낮았다(2.884 ± 0.624, p = 0.038 and 8.594 ± 4.944, p = 0.027). COPD가 있는 흡연자들의 Pi10 (4.427 ± 0.437, n = 7)이 COPD가 없는 비흡연자들보다 약 0.4 mm 두꺼웠다(4.001 ± 0.108, n = 14, p = 0.005). 그러나 평균감쇠계수와 저감쇠영역%에서는 유의한 차이가 없었다. 결론 정상 chest CT를 보이더라도 QCT로 COPD의 유무와 상관없이 흡연자들의 소기도가 두꺼운 것을 알 수 있으며 이는 폐실질 변화보다 더 선행한다.

The purpose of this study was to compare the dietary habits, nutrient intake, bone mineral density(BMD) and bone metabolism in Korean male collegians as related to smoking situation. One hundred sixty one young adult males at the age of 20-26 participated in this study. The subjects were divided into four groups: non smoker(n=42), light smoker(n=34), moderate smoker(n=49) and heavy smoker(n=36). The anthropometric characteristics, smoking situations, dietary habits and nutrient intakes were observed. Bone status of the calcaneus was measured by using quantitative ultrasound(QUS). Bone metabolism markers including serum alkaline phosphatase activity(ALP) and N-mid osteocalcin(OC) were analyzed. There were no significant differences in height, weight, BMI, energy and calcium intake among the four groups. Iron intake of moderate and heavy smoker was significantly lower than that of light smoker. Heavy smokers consumed significantly lower vitamin C than moderate smokers, and their coffee consumption and lifetime alcohol consumption were significantly highest among the 4 groups. QUS parameters and serum ALP were not significantly different among the four groups. Serum OC levels were significantly lower in heavy and non smoker group compared to the moderate smoker group. In conclusion, heavy smokers in young male collegians had undesirable lifestyle and dietary habits, like as high consumption of coffee and alcohol, and low intake of Fe and vitamin C. Although, there was no significant difference in their current bone status from the other groups, these undesirable factors with heavy smoking may affect their bone health in the long term.

Background: Research indicates that oxidative stress induced by smoking plays a role in breast cancer. In view of these reports, we aimed to study th relationship between smoking and oxidative stress in breast cancer patients from the western region of Nepal. Materials and Methods: The study included a control group of 42 females (non-smoking healthy women) and a test group sudivided into Group I consisting of 46 female breast cancer patients who were smokers and Group II consisting of 42 non-smoking breast cancer patients. Detailed history of the patients was collected with the help of pre-test proforma. Plasma levels of malondialdehyde (MDA), total antioxidant activity (TAA) which represents total dietary antioxidants, vitamin C and ${\alpha}$- tocopherol were estimated by standard methods. Statistical analysis was done using SPSS version 16. Results: The plasma MDA, TAA, vitamin C and ${\alpha}$- tocopherol were $1{\pm}1.4nmol/ml$, $918{\pm}207{\mu}mol/L$, $1{\pm}0.24mg/dL$ and $0.94{\pm}0.31mg/dL$ in controls, $5{\pm}1.2nmol/ml$, $458{\pm}166{\mu}mol/L$, $0.64{\pm}0.32mg/dL$ and $0.5{\pm}0.3mg/dL$ in Group-I and $2.56{\pm}1.2nmol/ml$, $663{\pm}178{\mu}mol/L$, $0.78{\pm}0.2mg/dL$ and $0.77{\pm}0.2mg/dL$ in Group- II, respectively. Vitamin C, ${\alpha}$- tocopherol and TAA (p=0.001) were significantly reduced whereas MDA (p=0.001) was significantly raised in Group-I when compared to controls and Group-II. Conclusions: We observed a significant rise in oxidative stress and low levels of antioxidants in breast cancer patients with smoking habit. It is well known that free radicals facilitate the progression of breast cancer, possibly increasing the risk of progression to the next stage.

Dark-blue pigmentation has been thought to be related to smoking or occupational exposure and has been regarded as anthracotic pigmentation. It is also frequently observed in non-smokers without occupational exposure, but there is no proven mechanism of pigmetation. To investigate clinical features and to find other causes of dark-blue pigmentaion, retrospective analysis was done in 59 patients who showed anthracotic pigmentation on bronchoscopy during recent 5 years in Seoul National University Hospital. The results were as follows; 1) Forty cases were non-smokers, while smokers were 19 cases. 2) Fifteen cases had history of tuberculosis, but there was no history of environmental exposure. 3) Mediastinal calcification was observed in 89.7%. 4) There was significant bleeding without exception when biopsy was done at the pigmentation site. 5) In patients with pigmentation only, hemoptysis and productive cough were main chief complaints, and chest X-ray showed atelectasis, infiltration, mass, or pleural change. 6) The number of patients whose lesion of X-ray corresponds to pigmentation site were 19/30 in tuberculosis, 4/30 in DILD and 7/30 in other diseases.
