Yes / Introduction Despite the well-known link between stress and smoking, evidence for associations between economic recession, financial stress and smoking is contradictory. In this study we assess whether women were more likely to continue smoking during pregnancy if they were exposed to the UK 2008-2010 economic recession during pregnancy than those who were unexposed, and whether this relationship is mediated by financial stress. Methods We used cross-sectional data on 2775 pregnant women who were regular smokers before pregnancy and who were enrolled in the UK Born in Bradford cohort study between March 2007 and December 2010. The cut-off date for exposure to recession was set at August 1, 2008, based on local and national economic data. Multivariable logistic regression analysis included potential confounders: maternal age, parity, cohabitation, ethnicity and maternal age. The mediating role of financial stress was analysed using ‘worse off financially’ and a ‘difficult financial situation’ as indicators of financial stress in Sobel-Goodman mediation tests with bootstrap resampling. Results After taking into account potential confounders, exposure to recession was associated with continued smoking during pregnancy (OR 1.19, 95% CI 1.01; 1.41, p=0.03). A worse financial situation and difficult financial situation were identified as mediators, explaining 8.4% and 17.6%, respectively, of the relationship between exposure to recession and smoking during pregnancy. Conclusions Smoking during pregnancy is associated with exposure to the UK 2008-2010 economic recession during pregnancy, and this relationship is partly mediated by financial stress. / supported by the Born in Bradford study funding.

MPH / Department of Public Health / Background: Globally, cigarette smoking is causing preventable deaths in developing countries affecting especially the youth. Historically, cigarette smoking is known to be more common among adults but is also becoming common among students. Purpose: The study aimed to investigate factors contributing to cigarette smoking and its health consequences amongst students of the University of Venda in South Africa. Methodology: A quantitative approach using a descriptive cross- sectional design was adopted. Convenience sampling was used to randomly select 428 respondents. A self-reporting questionnaire with closed ended questions was administered to respondents between the ages of 17-40 years who suited the inclusion criteria. Permission to conduct the research was obtained from the Ethics Committee of the University of Venda. Data were analysed using SPSS version 23 and presented in the form of tables and charts. Pearson’s chi squares were used to test significant relationships between variables and smoking status. Results: A total of 407 students participated in the study. Of the 407, 208 (51%) of respondents were female students. The mean age of the study population was 24 years. Of these 407, 175(43%) reported being smokers 232 (57%) were nonsmokers. More smokers were observed among the male respondents and registered for first and second years. There was a significant relationship between age, gender, religion, school of affiliation, amount of pocket money and smoking status (P-value=0.05).The results showed that the majority of the respondents285 (70%) agreed to the belief that students smoked cigarettes due to availability of cigarettes at every corner of the campus, 281 (79%) peer influenced by friends 289 (71%) family members who smoke, and 313 (76.8%)increase social interaction. The majority of the students were knowledgeable about health consequences caused by smoking. Nonsmoking students were more knowledgeable about harmful effects of smoking as compared to smokers (P=0.00. Conclusion: The study concludes that students smokes cigarettes due to being a friend with someone who smokes, being in new a environment, stress, depression, observation of other students smoking, no signage prohibiting smoking and lack of knowledge regarding health / NRF

The diploma thesis is focused on the smoking issue of adolescents of different secondary schools in Pilsen. The theoretical part covers the current situation of smoking habit in the Czech republic and its legislation, and it clarifies a few definitions of addictions. This part also describes different types of smoking, including risks, which are connected with them. There are also adolescent development descriptions, their personalities and social abilities. Another part of the thesis covers important life factors. The last chapter includes smoking prevention. The empirical part explores an attitude to smoking of students of particular types of secondary schools of Pilsen (secondary vocational schools and grammar schools) and it compares them. The research was done by questionnaire. The data analysis brought information about smoker and non-smoker number while the sex, type of school, family, friends and other aspects were taken into consideration. Key words smoking (habit), tobacco, cigarettes, marijuana, water pipe, e-cigarette, adolescence, smoking prevention

OF THE THESIS Name: Mgr. Markéta Šídová Specialization: Adiktologie Head of the thesis: Mgr. Lenka Šťastná, Ph.D. Pages: 145 The name of thesis: Tobacco smoking and motivation to change in relation to pregnancy Abstract: Background: The pregnancy gives the smoking women the opportunity to change their attitude to smoking tobacco. In the Czech Republic is still missing a study describing the motivation to change smoking specifically in connection with pregnancy. Goals: Describe the basic motivation to stop smoking by pregnant women. Methods: Quantitative survey. The questionnaire consists of four sections (anamnesis, gathering information about smoking during pregnancy, motivation to change smoking behaviour, Fagerström Test of Nicotine Dependence). Motivation section is inspired by Reasons for Quiting Scale (RFQ). Evaluation using the descriptive statistics and non-parametric statistical tests. File: The study analyses two sets of pregnant women - electronic (collection via web form, N = 96) and clinical (collection from the Department of Gynaecology and Obstetrics, 1st Faculty of Medicine and VFN, N = 40). The files are divided into 4 subgroups according to the current smoking behaviour. Results: Most women in both groups do not smoke and have never smoked or stopped in connection with pregnancy....

Background: We investigated whether maternal smoking in the first year of life or any current parental smoking is associated with childhood or adolescent body mass index (BMI). Methods: Secondary analysis of data from a multi-centre, multi-country, cross-sectional study (ISAAC Phase Three). Parents/guardians of children aged 6-7 years completed questionnaires about their children's current height and weight, whether their mother smoked in the first year of the child's life and current smoking habits of both parents. Adolescents aged 13-14 years completed questionnaires about their height, weight and current parental smoking habits. A general linear mixed model was used to determine the association between BMI and parental smoking. Results: 77,192 children (18 countries) and 194 727 adolescents (35 countries) were included. The BMI of children exposed to maternal smoking during their first year of life was 0.11 kg/m 2 greater than those who were not (P = 0.0033). The BMI of children of currently smoking parents was greater than those with non-smoking parents (maternal smoking: +0.08 kg/m 2 (P = 0.0131), paternal smoking: +0.10 kg/m 2 (P < 0.0001)). The BMI of female adolescents exposed to maternal or paternal smoking was 0.23 kg/m 2 and 0.09 kg/m 2 greater respectively than those who were not exposed (P < 0.0001). The BMI of male adolescents was greater with maternal smoking exposure, but not paternal smoking (0.19 kg/m 2 , P < 0.0001 and 0.03 kg/m 2 , P = 0.14 respectively). Conclusion: Parental smoking is associated with higher BMI values in children and adolescents. Whether this is due to a direct effect of parental smoking or to confounding cannot be established from this observational study. / This work was supported by Cure Kids New Zealand through a grant to Professor E Mitchell and Dr I Braithwaite.

The topic of this diploma thesis is ´Smoking in restaurant facilities in Pilsen city center´. Smoking in restaurant facilities harms not only their visitors but especially their employees. This group of citizens becomes passive smokers for the entire working time which may have negative health consequences. The main goal of this thesis was to map out the problem of smoking in restaurant facilities from their employee´s point of view. Three research questions have been determined towards fulfilling this goal. The research was implemented with the help of qualitative survey. Semi-structured in-depth interview was carried out with 13 respondents who had been chosen through the snowball sampling method. Information was evaluated through the open coding method and it has responded to the research questions. The first research question - What are the smoking habits of smoking restaurant facility employees? The research has proven that the amount of cigarettes smoked by the smoking restaurant facility employees has raised. The second research question - How do the employees of smoking restaurant facilities perceive the risk of passive smoking? Respondent´s answers have provn that they do not perceive passive smoking to be a risk factor which might harm their health. Only a minor part of respondents minds working in a smoking environment. The third research question was put this way: What is the attitude of employees in smoking restaurant facilities towards the new planned anti-smoking legislation? The research has proven that most respondents does not wish the acceptance of smoking prohibition in restaurant facilities. The reasons are concerns for their jobs, decrease in revenue, refusal of prohibition in general ort he fact that they themselves are smokers. Only a small number of respondent sis acutally concerned about their health and would welcome an amendment to the Act. A short intervention was carried out with the respondents within the research, which was supposed to inform the employees of restaurant facilities about the risks of passive smoking. The research has proven that employees of smoking restaurant facilities do not perceive the risk of passive smoking really. They are often exposed to tobacco smoke even in their leisure time. The most effective prevention may be ensured by politicians who would enforce a stricter legislation.

Nowadays is smoking still tolerated social phenomen in this country, despite belongs to the biggest killer in a human history and every day year die 5 milion people for this. Especially dangerous is smoking among young people, because they aren't grown up physical or mentally and therefore is smoking for them so dangerous. 78% of the adult smokers, started smoke before sixteen. In this paper I present the statistics from actual researches and additional analyses of smokers. In comparison with other european states is Czech republic on the second places in number of young smokers. The influence of social environment is crucial for if people started smoke or not. The government should protect smokers and non-smokers due to the effect of smoking in public places. In the Czech has tobacco industry strong position and there is no political will to change it although people want it.

Background: Measurement of carbon monoxide in expired air samples (ECO) is a non-invasive, cost-effective biochemical marker for smoking. Cut points of 6. ppm-10. ppm have been established, though appropriate cut-points for pregnant woman have been debated due to metabolic changes. This study assessed whether an ECO cut-point identifying at least 90% of pregnant smokers, and misidentifying fewer than 10% of non-smokers, could be established. Methods: Pregnant women (N=167) completed a validated self-report smoking assessment, a urine drug screen for cotinine (UDS), and provided an expired air sample twice during pregnancy. Results: Half of women reported non-smoking status early (51%) and late (53%) in pregnancy, confirmed by UDS. Using a traditional 8. ppm. +. cut-point for the early pregnancy reading, only 1% of non-smokers were incorrectly identified as smokers, but only 56% of all smokers, and 67% who smoked 5. + cigarettes in the previous 24. h, were identified. However, at 4. ppm. +, only 8% of non-smokers were misclassified as smokers, and 90% of all smokers and 96% who smoked 5. + cigarettes in the previous 24. h were identified. False positives were explained by heavy second hand smoke exposure and marijuana use. Results were similar for late pregnancy ECO, with ROC analysis revealing an area under the curve of 95 for early pregnancy, and 94 for late pregnancy readings. Conclusions: A lower 4. ppm ECO cut-point may be necessary to identify pregnant smokers using expired air samples, and this cut-point appears valid throughout pregnancy. Work is ongoing to validate findings in larger samples, but it appears if an appropriate cut-point is used, ECO is a valid method for determining smoking status in pregnancy.
