This study was conducted to investigate the effects of passive inhalation of cigarette smoke and the correlation between change of flicker value and active or passive smoking in poorly ventilated room. Forty five male students were tested by divided into four experimental groups composed of active and passive smokers and three control groups. Each four experimental groups were exposed to smoke for Two hours in enclosed room. Vital capacities, flicker values, blood carboxyhemoglobin levels and carbon monoxide concentration in room air were estimated before, during and after the exposure, and amounts of smoking or smoke exposure during two hours were also noted. The results obtained were as follows; 1. Concentration of carbon monoxide in air and increase of blood carboxyhemoglobin level (% COHb) were positively correlated with smoking amount. 2. Increase of blood carboxyhemoglobin in passive smokeres, in average, were about seventy six percent of that in smokers, as 2.2% vs. 2.9%. 3. Comparison with published data showed that Peterson's equation gave most similar result to this study in estimation of increase of blood carboxyhemoglobin level. 4. During the exposure, flicker values fell steadily in both experimental groups and control groups as time passed. Flicker values were, however, elevated again in experimental groups after exposure, despite the fact that values still fell in control groups. 5. Blood carboxyhemoglobin and flicker value were negatively correlated and this correlationship was stronger in passive smoker than in active smoker. 6. Multiple regression equation between flicker value and exposure time and blood carboxyhemoglobin level was expressed as: Flicker value=41.6-0.2 COHb%-0.9Hour, 7. In general, it is suggested that biological criteria would be more preferrable than chemical criteria in establishment of statutory limitation of smoking in enclosed spaces.

The subjects of this study were 415 children in the first to third grade selected from 4 primary schools. Among them, 212 children belong to the experimental group, and 203 children were in the control group. The program was provided respectively to first, third and fifth grade children for 2, 4 and 6 teaching-hours from 2013.1.1 to 2013.12.19. To measure the effects of the program, the knowledge and attitudes on/toward smoking, self-concept were used as the research tools. Before and after program-implementation, there were significant differences in knowledge of smoking, but no differences in attitudes and self-concept. A smoking prevention program for primary school children should be applied step-by-step in conjunction with the regular education curriculum. In addition, the program should aim for long-term effects rather than short-term effects.

This investigation was performed to summarize a few prominent features of smoking prevention program studies and to evaluate the quality of smoking prevention program studies using the Quality of Study Rating Form (QSRF). 24 school-based smoking prevention programs were subjected to an evaluation of study quality using QSRF. Study quality was 57.29 points out of 100 points on average, so it cannot be said that study quality was good. Most of the studies described the subjects and the intervention contents and intervention time. 50% stated where the intervention occurred specifically, 50% of the studies either discussed a specific theory that justified the use of one or more intervention methods, or they cited literature said to support the chosen intervention method. Only one study assigned subjects randomly to experimental groups or control groups and 50.0% of the studies showed baseline equality. There was no study where subjects were blind to being in the treatment or control group or where subjects were selected randomly by random sampling procedure. 79.2% of the studies had non-treated control groups and 20.8% of the studies had comparison groups with other treatments in the form of either other delivery methods or other contents. Sample sizes were larger than 21 in the experimental group for all studies. 75% of the studies stated face validity of outcome measure or cited from previous literature. 58.3% of the studies tested reliability and 45.8% reported the reliability measure was a figure of .70 or greater. There was no study where those rating outcomes were rated blind, because researchers generally collected data by themselves. Outcome measures were taken only after the intervention was completed and tests of statistical significance were generally referred to statistical method and p value in all studies. All studies met the criteria that follow-up was greater than 75%. The implications for the future studies were discussed.

Background: In Jordan, a developing country with a high tobacco burden and where roughly 40% of cancers are tobacco-related, limited knowledge exists on public awareness regarding tobacco. This is a hindrance for experts seeking to strengthen anti-tobacco health promotion and counter growing tobacco use. We sought to evaluate public awareness regarding tobacco; to gauge exposure to anti-tobacco public messages; and to draw attention to the lay public's informational needs. Materials and Methods: A cross-sectional survey of lay public in the capital, Amman, capturing knowledge regarding tobacco harms and anti-tobacco laws, perceptions regarding tobacco use and control, and exposure to and recall of anti-tobacco messages, was conducted. Statistics on perceptions were generated and analyzed by smoking status and sociodemographic factors. Multivariate regression was performed to estimate independent associations of smoking and sociodemographic factors with knowledge. Results: Of 1,169 respondents, 17.8% could recall specific anti-tobacco messages. With regard to knowledge, despite high proportions of respondents exhibiting knowledge for individual statements regarding tobacco health harms, variables capturing breadth of knowledge showed that much lower proportions could correctly identify all the listed health harms of tobacco, and all listed Jordanian anti-tobacco regulations (47.5% and 36.2%, respectively). On multivariate analysis, breadth of knowledge varied by smoking status, age and educational level. Conclusions: There is need for more salient, evocative and multi-faceted anti-tobacco messages in Jordan, tailored to subgroups, given detected variability in knowledge across smoking status and sociodemographic characteristics.

Background: Based on the importance of ceasing smoking programs to control the regional disparity of smoking behavior in Korea, this study aims to reveal the variation of smoke rate and determinants of it for 229 provinces. An evaluation of the relative efficiency of the cease smoking program under the consideration of regional characteristics was followed. Methods: The main sources of data are the Korean Statistical Information Service and a national survey on the expenditure of public health centers. Multivariate regression is performed to figure the determinants of regional variation of smoking rate. Based on the result of the regression model, clustering analysis was conducted to group 229 regions by their characteristics. Three clusters were generated. Using data envelopment analysis (DEA), relative efficiency scores are calculated. Results from the pooled model which put 229 provinces in one model to score relative efficiency were compared with the cluster-separated model of each cluster. Results: First, the maximum variation of the smoking rate was 16.9%p. Second, sex ration, the proportion of the elder, and high risk drinking alcohol behavior have a significant role in the regional variation of smoking. Third, the population and proportion of the elder are the main variables for clustering. Fourth, dissimilarity on the results of relative efficiency was found between the pooled model and cluster-separated model, especially for cluster 2. Conclusion: This study figured regional variation of smoking rate and its determinants on the regional level. Unconformity of the DEA results between different models implies the issues on regional features when the regional evaluation performed especially on the programs of public health centers.

Background: Smoking in adolescence leads to an intensified addiction to nicotine when physical and mental growth has not yet been completed. With the advent of e-cigarettes, the rate of e-cigarette use among Korean adolescents has been steadily increasing. To date, studies on e-cigarettes and oral health, especially on the relationship between smoking styles and oral health in adolescents, are limited. Therefore, this study aimed to identify the risk factors for oral health problems caused by the repeated use of conventional cigarettes and e-cigarettes. Methods: This explanatory research study compared the adolescents' experiences of periodontal disease symptoms according to smoking type through a secondary analysis of the original data from the 15th Adolescent Health Behavior Survey (2019). Cross-analysis was performed to compare the smoking patterns according to the adolescents' general characteristics. Finally, a binary logistic regression analysis was performed to determine how smoking characteristics affect the adolescents' experience of periodontal disease symptoms. Results: In terms of patients' general characteristics, significant differences were observed in sex, school level, grades, household economic status, type of residence, and father's education level between adolescents who smoked conventional cigarettes alone and those who smoked both conventional cigarettes and e-cigarettes (p<0.05). After checking the factors affecting the smoking pattern and the experience of periodontal disease symptoms in adolescents, it was found that the duplicate smoking group was more likely to experience periodontal disease symptoms (odds ratio, 1.20) than the group that smoked conventional cigarettes alone (p<0.05). Conclusion: Duplicate smokers experienced more symptoms of periodontal disease than those who smoked cigarettes alone. Based on the findings of this study, smoking cessation counseling according to the smoking type and differentiated education for oral health promotion should be provided.

Purpose: The purpose of this study was to identify the effect of a community-based health promotion program for elders. Method: The research design was a nonequivalent control group experimental design. The participants were 415 elders who were above 65 years of age (mean age: 80.7, experimental group: 126, control group: 289). For 4 months, the health promotion project which consisted of health education and activity related to smoking, drinking, nutrition and exercise was given to the experimental group. Data were analyzed using descriptive statistics, ${\chi}^2$-test, and t-test with the SAS V8e program. Result: After the intervention, the experimental group showed a higher level of health promotion behavior compared to the control group in health education experience, exercise, smoking, and drinking. There were no differences between the experimental and control groups for nutrition, or high risk drinking and smoking. Conclusion: The results of this study show that the health promoting program for elders provides useful information in developing effective community-based programs and can be recommended as effective interventions to improve the health promoting behavior of elders.

As stomach cancer is very prevalent in Koreans, various factors, especially dietary factors, related to stomach cancer incidence were examined in a case-control study. The study population consisted of 105 individual s diagnosed for stomach cancer in two general hospitals and 124 control subjects, matched for age and sex, in Seoul. Data for general characteristics, family history, smoking and alcohol consumption, personality , dietary habits and food preference were obtained by self-administered questionnaire and personal interview. Heredity was found to be one of the most important factors causing stomach cancer. In addition, genetic inheritance tended to differ between the sexes. The male patients showed significantly higher incidence of their father's relatives than mother's relatives but the female patients showed higher incidence of their mother's relatives that father's relatives. Smoking was significantly related to stomach cancer. It was also found that the cases drank alcohol more frequently and in much greater quantity than the controls. Personality was related to the incidence of stomach cancer. The cases tended to be more sensitive , impatient, and anxious to do things quickly. With regards to dietary habits, the male cases had meals significantly more irregularly than the male controls. The relative risk of preferencefor salty food and ramen showed to be significantly very high. The male cases consumed carbonated beverages and instant foods, low intake of green yellow vegetables, smoking of cigarettes and drinking of alcohol may contribute to the risk of stomach cancer.

Background: In the year 2010, it is estimated that nearly 0.36 million new cases and 0.19 million deaths with Non-Hodgkin lymphoma occurred. In India, among males, NHL incidence rates vary across the country which has encouraged us to conduct a case-control study to study risk factors. Materials and Methods: The present unmatched hospital-based case-control study conducted at Tata Memorial Hospital included subjects registered between the years 1997-99. There were 390 'lymphoma cases' and 1,383 'normal controls. Results: Data on age, tobacco habits, occupational history, dietary factors, tea, coffee were collected by the social investigators. Univariate and multivariate methods were applied for obtaining the odds ratios for risk factors. Conclusions: In the study, cigarette smoking (OR=2.0) and bidi smoking (OR=2.8), were associated with excess risk of lymphoma. Among the dietary items, only consumption of mutton showed 7.3-fold significant excess risk for lymphoma. Consumption of milk showed a 6-fold excess risk (OR=1.5); while coffee showed a 50% reduction in risk for lymphoma. Among occupational exposure, exposure to use of pesticides showed 3-fold excess risk for lymphoma.

The prevalence of alcoholism among elderly population is reported to be high in rural areas in Korea. Chronic abuse of alcohol can lead to the development of vitamin B deficiency through inadequate intake, altered absorption and metabolism, and increased excretion. The present study was conducted to assess vitamin B1 and B2 status in seventeen alcohol dependent subjects who do not exhibit any clinical neurological symptoms. Vitamin B1 and B2 nutritional states were determined enzymatically by measurement of transketolase and glutathione reductase activities in erythrocytes, respectively. And dietary intakes of nutrients were determined by a 24-hr recall method. The mean percent activation of erythrocyte transketolase was significantly higher in alcoholics than in alcoholics than in control (p<0.05). The proportion of subjects with a low and borderline status of vitamin B1, was significantly higher in alcoholics than in control (p<0.05). The mean percent activation of erythrocyte glutathione reductase was not different between alcoholics and control. And the proportion of subjects with low and borderline status of Vitamin B2, was higher in alcoholics than in control (p<0.1). Vitamin B1 and B2 status were significantly decreased in alcoholics who were smoking cigarettes compared to non-smoking and non-alcoholic subjects(p<0.05). Whether vitamin supplementation improves the vitamin status of alcohol dependent subjects remains to be researched.
