  • 전 세계적으로 담배흡연자의 심혈관 위험 감소와 금연을 위한 대안으로 전자담배 이용이 급속하게 확산되고 있지만 니코틴을 포함한 잠재적 유해화합물을 함유한 전자담배의 심혈관 효과는 불분명하다. 본 연구는 전자담배 사용에 따른 심장자율신경조절 변화를 관찰하고 급성적인 교감신경흥분효과 및 부교감신경활동 저하 반응을 궐련담배 흡연과 직접 비교하려는 목적으로 수행되었다. 41명의 젊고 건강한 흡연남성들을 대상으로 자료 분석을 수행하였으며, 무작위 교차 설계에 의해 1주의 wash-out period를 적용하여 전자담배와 궐련담배 세션이 각각 실시되었다. 전자담배는 흡연 시를 포함한 흡연 후 5분까지, 궐련담배의 경우 흡연 시 및 흡연 후 최대 30분까지 교감신경활성화 및 부교감신경 감소가 관찰되었다. 두 제품 간 비교에서, 흡연 시를 포함한 흡연 후 30분 동안의 HRV 분석에서 전자담배는 궐련담배에 비해 비교적 교감신경흥분효과 및 부교감신경저하에서 적은 변화수준 및 단시간 변화를 제공하는 것으로 나타났다. 이상의 결과들은 비록 전자담배가 궐련담배에 비해 심장자율신경조절에서 상대적으로 완화된 효과를 제공한다고 할지라도 전자담배 내 니코틴 및 잠재적 위험요인들을 고려해 볼 때 급성적인 교감신경흥분작용 및 부교감신경의 저하를 야기함으로 과도한 사용에 주의가 요구된다.

  • 연구 배경 : 우리나라에서는 다른 나라에 비해 약초 등을 이용해 만든 흡연대용품으로 금연을 시도하려는 흡연자들도 많고 이에 따라 여러 가지 다양한 제품 등이 판매되고 있는데 이들의 기관지, 폐에 대한 안정성에 관한 연구는 아직 부족한 상황이다. 특히 흡연자중 일부는 이런 금연 보조제를 사용하는 과정에서 이들을 상용하게 되어 시판되는 금연 보조담배의 장기적 사용시 인체의 안정성 여부에 대한 연구는 중요하리라 사료된다. 방 법 : 일반담배 및 금연 보조담배 3종의 담배연기추출물(cigarette smoke extract, CSE)을 기관지 상피세포에 24시간 노출 후 배양액에서 IL-6를 측정하였고 일반담배 및 허브담배, 쑥담배 노출 후 세포에서 IL-6 m RNA를 측정하여 비교하였다. 항산화 효과를 가진 N-acetyl-L-cysteine(NAC)를 일반 담배 및 금연보조담배 추출물에 함께 투여해 IL-6의 증가 억제여부를 보았다. 결 과 : 대조군에 비해 일반담배 및 금연보조담배3종에서 기관지 상피세포에 노출 시에 모두 의미 있는 IL-6증가를 관찰할 수 있었고, IL-6 m RNA도 같은 경향으로 증가 하였다. NAC를 함께 투여 시 일반 담배 및 허브담배 금연초에서는 IL-6의 증가를 의미 있게 억제하였지만 쑥담배에서는 억제하지 못하였다. 결 론 : 현재 우리나라에서 시판되고 있는 금연 보조담배 3종(허브담배, 쑥담배, 금연초)은 일반담배처럼 기관지 상피세포에 염증을 유발할 수 있어 장기적 사용시 인체의 안정성 여부에 대한 연구는 중요하리라 사료된다.

  • The purposes of this study were to investigate the relationship between cigarette smoking levels and periodontal status. 199 subjects, consisting of male 127 and female 72, classified by smoking levels and duration were selected: Patients who had smoked for more than 20 cigarettes/day were considered heavy smokers, 10 to 19, moderate smokers; 1-9, light smokers:0, non-smoker. And smokers were divided into ones who had smoked for more than 20 years, 10-19 years, less than 10 years and non-smokers. Heavy smokers and moderate smokers showed significantly greater pocket depths, less clinical attachment levels, more molar furcation involvements, greater alveolar bone loss and higher scores of plaque index than light smokers and non-smokers,(p < 0.05). When the duration of smoking was considered as a factor, scores of clinical parameters were worse and alveolar bone loss were significantly greater in long-term smokers, who had smoked for more than 20 years. In conclusion, cigarette smoking is associated with periodontal status.

  • Owing to the increase in price of cigarettes in Korea, herbal cigarettes have received increasing attention as a non-smoking aid; however, its safety has hardly been studied. We analyzed some of the toxic components in the mainstream smoke of herbal cigarettes, performed a mutagenicity test on smoke condensates for safety assessment, and compared the results with the corresponding values of a general cigarette with the same tar content. Herbal cigarette "A" was smoked using automatic smoking machine under ISO conditions in a manner similar to general cigarette "T". The tar content measured was higher than that inscribed on the outside of a package. The mainstream smoke of herbal cigarette "A" did not contain detectable levels of tobacco-specific nitrosamines and nicotine. Carbon monoxide and benzo(${\alpha}$)pyrene contents in herbal cigarette "A" were higher than those in the general cigarette "T". The phenolic contents such as hydroquinone, resorcinol, and catechol in herbal cigarette "A" were higher than those in the general cigarette "T", but cresol contents in herbal cigarette "A" were lower than those in the general cigarette "T". The content of aromatic amines such as 4-aminobiphenyl in herbal cigarette "A" was higher than that in the general cigarette "T"; however, this difference was not statistically significant. On the other hand, 1-aminonaphthalene, 2-aminonaphthalene, and 3-aminobiphenyl contents in herbal cigarette "A" were lower than those in the general cigarette "T". The smoke condensates of herbal cigarette "A" exhibited a higher mutagenic potential than the condensates from the general cigarette "T" at the same concentration. We concluded that the mainstream smoke of herbal cigarette contains some toxic components, the smoke condensates of herbal cigarettes are mutagenic similar to general cigarette because of combustion products, and that the evaluation of the chemical and biological safety of all types of herbal cigarettes available on the market.

  • Objectives: This study aimed to predict the 10-year impacts of the introduction of pictorial warning labels (PWLs) on cigarette packaging in 2016 in Korea for adults using DYNAMO-HIA. Methods: In total, four scenarios were constructed to better understand the potential health impacts of PWLs: two for PWLs and the other two for a hypothetical cigarette tax increase. In both policies, an optimistic and a conservative scenario were constructed. The reference scenario assumed the 2015 smoking rate would remain the same. Demographic data and epidemiological data were obtained from various sources. Differences in the predicted smoking prevalence and prevalence, incidence, and mortality from diseases were compared between the reference scenario and the four policy scenarios. Results: It was predicted that the optimistic PWLs scenario (PWO) would lower the smoking rate by 4.79% in males and 0.66% in females compared to the reference scenario in 2017. However, the impact on the reduction of the smoking rate was expected to diminish over time. PWO will prevent 85 238 cases of diabetes, 67 948 of chronic obstructive pulmonary disease, 31 526 of ischemic heart disease, 21 036 of lung cancer, and 3972 prevalent cases of oral cancer in total over the 10-year span due to the reductions in smoking prevalence. The impacts of PWO are expected to be between the impact of the optimistic and the conservative cigarette tax increase scenarios. The results were sensitive to the transition probability of smoking status. Conclusions: The introduction of PWLs in 2016 in Korea is expected reduce smoking prevalence and disease cases for the next 10 years, but regular replacements of PWLs are needed for persistent impacts.

  • Background: The tobacco epidemic is a heralding health menace, particularly among college students. Tobacco usage among young can have an especially devastating effect as they can be exposed for longer periods. Data to estimate the prevalence of tobacco use in young adults will be a valuable addition to the existing resources. Materials and Methods: An analytical cross-sectional study was therefore carried out in Mangalore city using a pre-tested, self-administered questionnaire adapted from the Global Youth Tobacco Survey (GYTS) with a representative sample of 720 students aged 18-20 years selected from degree colleges by multi-stage random sampling. Results: Prevalence of 'ever users' and 'current users' of smoking were 20.4% and 11.4%, respectively. The mean age at initiation of cigarette smoking was 16 years and the majority (31 %) smoked in public places. Interestingly, 84% of them knew about the harmful effects of cigarette smoking. About one half of smokers had some or most of their friends smoking. Multivariate analysis revealed gender (OR=8.585: CI-3.26-22.5), pocket money (OR=4.165; CI=1.76-9.82) and peer's smoking habit (OR= 5.15; CI-2.21-11.9) have higher odds as correlates of tobacco usage among college students. Conclusions: It is of prime importance to highlight the role of prevention of smoking initiation rather than subsequently trying to stop the habit. Comprehensive interventions embracing family, friends and social milieu are needed to reduce tobacco use among students in India.

  • Recently WHO death from smoking-related illness would increase more than a thousand in the future. But in spite of various harms, smoking cigarette in developing countries is increasing especially in the adolescents. So in order to evaluate whether auricular acupuncture therapy is effective to quit smoking, clinical examination was carried out. And the results showed that age of starting smoking become lower. The cause of smoking is curiosity, relaxation, envy and comradeship. For this reason they want to stop smoking but feel it is difficult to do. Cigarette smoking didn't show any significant change after auricular acupuncture in both control and therapy. And physical and psychological change did not present any significance. However, auricular acupuncture therapy was appeared to be effective to stop smoking. So with these results, further systemic research to examine the effect of auricular acupuncture is seem to be necessary.

  • 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.

  • We evaluated cigarette smoking as a risk factor for prostate cancer in a prospective, population-based cohort study. The subjects were 14,450 males among the participants in the Seoul Male Cancer Cohort Study who had at least 1-year follow-up. They were followed up between 1993 and 2008. During the 16-year follow-up period, 87 cases of prostate cancer occurred over the 207,326 person-years of the study. The age-adjusted relative risks of past and current smokers at entry were 0.60 (95%CI: 0.34-1.06) and 0.70 (95%CI: 0.43-1.13), respectively, suggesting that cigarette smoking may not be a risk factor for prostate cancer. The relationship between prostate cancer and other modifiable factors, such as Westernized diet, should be studied with the goal of establishing prevention programs for prostate cancer.
