This study investigated the relationship between smoking cessation and cognitive factors of attributional style, self-efficacy and locus of control. The roles of examined as they contributed to the prediction of smoking status. Questionnaires designed to measure these cognitivevariables, were administered to participants of smoking cessation programs at two times during the study; immediately before participation in the smoking cessation program and immediately after completion of the program. Smoking status was assessed at these times, as well as via telephone twice after the program's completion. Subjects were obtained from 16 American Cancer Society smoking cessation clinics in the Southern California area. The results of stepwise discriminant analyses of variance successfully predicted smoking status at end-of-clinic and follow-up periods, using a combination of demographic, smoking behavior and cognitive predictors. Cross-validations of the predictive models also were able to predict smoking status at end-of-clinic and follow-up. Additional analyses included stepwise discriminant demographic and smoking behavior variables styles, as well as demographic and smoking behavior Cognitive Factors 5 analyses of participants who relapsed at follow-up, and a comparison of those who completed the program versus those who dropped out prematurely. Both analyses resulted in obtaining significant discriminant functions. A final analysis compared pre- and post-treatment responses on the cognitive measures via a 2 X 2 multiple analysis of variance (group X time). A significant interaction between group and time of assessment was obtained. / Department of Counseling Psychology and Guidance Services

Orientador: Irma de Godoy / Resumo: A Organização Mundial de Saúde (WHO) estima que haja cerca de 1100000 tabagistas, representando um terço da população mundial aproximadamente. As pesquisas mostram que o tabagismo é a principal causa prevenível de mortalidade nos países desenvolvidos. Os objetivos deste trabalho foram verificar a prevalência do hábito de fumar e identificar os sintomas respiratórios entre o corpo discente, docente e técnico-administrativo do Campus de Botucatu/Unesp. O estudo englobou as unidades do campus, discriminadas em Administração Geral e Unidades Universitárias (IB, FM, FMVZ e FCA), bem como os Cursos de Graduação relacionados (Biologia, Medicina, Enfermagem, Medicina Veterinária, Zootecnia, Engenharia Agronômica e Florestal). O instrumento utilizado para coleta dos dados foi o questionário da ATS-DLD, 78, adaptado à população local. Três mil e noventa indivíduos participaram da pesquisa, subdivididos em 1008 discentes, 302 docentes, 1673 servidores e 107 classificados como outros. A classificação da população de acordo com o hábito de fumar revelou 21,4% de fumantes, 15,9% de ex-fumantes e 62,7% de não fumantes. A variável sexo não apresentou diferença de proporção entre os fumantes. A maioria dos tabagistas consumia de meio a um maço diariamente, utilizava cigarro com filtro, tragava constantemente a fumaça e iniciou no hábito entre 11 e 21 anos. Os estados de estresse e as reuniões sociais foram as situações mais relacionadas ao tabagismo. Sintomas como tosse, catarro e chiado foram mais freqüentes entre os fumantes, ao passo que a falta de ar, entre os não fumantes. A maior proporção de tabagistas ocorreu entre indivíduos com graus de escolaridade primário e secundário incompleto, mais especificamente entre os servidores...

Smoking remains the leading cause of preventable mortality in developed countries. This study was designed to verify the smoking habit prevalence and identify smoking-related respiratory symptoms among the students, teachers and technical-administrative employees of the Campus from Botucatu/UNESP. The study involved all Units of the Campus, including the Courses of Biology, Medicine, Nursing, Veterinary, Zootechny, Agronomy and Forestry Engineering. Modified ATS-DLD questionnaire, 78 was the instrument used to collect the data. Three thousand ninety individuals answered the questionnaire: 1008 students, 302 teachers, 1673 employees and 107 classified as others. According to the smoking habit 21,4% were smokers, 15,9% ex-smokers and 62,7% no-smokers. The proportion of smoking between males and females was not statiscally different. The majority of the smokers was between 11 and 21 years old when started the habit, consumed a half to one pack daily, used filter cigarette and inhaled the smoke. Stress and social meetings were the most probable situations to trigger the smoking. Symptoms as coughing, expectoration and wheezes were more frequent among the smokers and dyspnea, among no-smokers. The higher proportion of smokers occurred among individuals with lower degree of formal education, more specifically among the technical-administrative employees. Among undergraduates there was a tendency for a higher proportion of smokers... (Complete abstract click electronic access below) / Mestre

Yes / Smokers usually lack confidence to quit smoking due to previous unsuccessful attempts. This study aimed to assess self-efficacy and quitting smoking among current adult smokers in Suva, Fiji. Methods: This study applied a mixed method design among current adult smokers who attended three randomly selected healthcare centers in Suva, Fiji between 1st May to 31st July 2020. A self-administered questionnaire was used to collect quantitative information on smoking and smoking cessation, self-efficacy, and stage of smoking. A semi-structured, open-ended questionnaire was used to guide the interviews. Qualitative data was transcribed and thematic analysis was applied to identify the common themes. Results: Four hundred sixty-four smokers participated in the quantitative study, with a mean age of 32.7 (SD=12.1). Only 16.6% of participants were at the stage of “Preparation” and 4.95% of them were at the stage of “Action”, according to the stage of change model. Majority of participants (43.1%) had low self-efficacy to quit smoking. Thirty-five smokers participated in in-depth interviews, with majority (48.57%) in the age group of 18-24. Two themes were identified including “Determinants of self-efficacy” and “Factors affecting quit smoking”. Conclusions: This study showed that adult smokers had low confidence to quit smoking. Developing a tailored intervention using models such as Transtheoretical Model (TTM) and stage of change may help smokers to quit smoking in Fiji. / This project was funded by the Fiji National University grant.

Rökning och passiv rökning är ett folkhälsoproblem som orsakar mycket ohälsa. På senare år har attityderna kring rökning ändrats från att ha varit rökarens rätt att röka till icke-rökarens rätt att slippa bli exponerad. Det här kan leda till konflikt mellan icke-rökare och rökare då många icke-rökarna vill slippa exponeras för tobaksrök samtidigt som rökarna enligt lag har rätt att röka i utomhusmiljö. Syftet med att göra den här studien är att undersöka rökares och icke-rökares upplevelser kring rökning med förhoppningen om att komma fram till en lösning där båda gruppernas upplevelser kan mötas. Icke-rökare vill slippa exponeras och rökare vill få röka i fred. Det finns ett problem med detta och det är att mycket av det tobakspreventiva arbetet som gjorts i Sverige syftat till att gör det besvärligt att vara rökare. Det finns därför ett motstånd mot att finna en lösning som rökarna kan uppfatta som positivt. Studien genomfördes genom att 20 intervjuer gjordes med 20 personer. Dessa valdes ut genom ett så kallat strategiskt urval som bestod utav 10 icke-rökare och 10 rökare, hälften män och hälften kvinnor, vilka analyserades med kvalitativ innehållsanalys. De fick svara på åtta frågor utifrån ett förutbestämd frågemall samt eventuella följdfrågor. Jag fann 12 huvudkategorier, sex från vardera grupp. I studien kom jag fram till att det handlar om de platser där grupperna mötts. Få icke-rökare störs utav rökning om de inte exponeras för den. De platser och situationer där icke-rökarna upplever att de exponeras för rökning är vid entréer till byggnader och i väntan på kollektivtrafiken. Det finns enligt resultatet stöd hos båda grupperna för införande av särskilda rökplatser. Motiven till dessa kan skilja sig åt något mellan grupperna, rökarna vill röka i fred och icke-rökarna vill slippa exponeras. Det finns önskan om ett avstånd om minst 15 meter från offentlig byggnad eller kollektiv trafik men det får enligt rökarna inte vara allt för långt bort. Det får inte bli för besvärligt för då ratas den särskilda platsen för rökning. Rökarna menar att det finns gränser för hur långt de ska behöva gå för att få röka. De vill inte heller behöva springa när tåget/bussen kommer. Vad som kanske är mest intressant när det gäller att icke-rökarna säger sig störas framförallt vid just entréer och platser där de väntar på kollektivtrafiken är att de platserna erbjuder exakt det som rökarna önskar vad gäller utformning av särskilda platser för rökning.  Det finns tak, askkoppar och sittplatser vilket gör att svaret på varför de röker just där kanske inte är så konstigt. Det finns inte något som hindrar dem från att röka där och platsen erbjuder exakt det som rökarna anser att en god rökmiljö ska erbjuda. / Smoking and passive smoking is a public health problem. It is derived from the smokers right to smoke and the non-smokers right not to be exposed. This can lead to conflict between non-smokers and smokers when non-smokers want to avoid exposure to tobacco smoke, while smokers are entitled by law to smoke in an outdoor environment. The purpose of this study is to investigate smokers and non-smokers experiences of smoking with the hope of finding a solution where both groups experiences can be met. Non-smokers do not want to be exposed to smoke and smokers want to smoke undisturbed. There is a problem with the tobacco prevention work carried out in Sweden due to the preventions are aimed to make it inconvenient for the smoker to smoke. Therefore, there is reluctance to find a solution that smokers may perceive as positive. The study was conducted through 20 interviews  with 10 non-smokers and 10 smokers, half of both gender, and qualitative content analysis ,and qualitative content analysis. I found 12 main categories, six from each group. In this study, I concluded that it is about the places where the groups met. Few non-smokers are disturbed of smoking if they are not exposed to it. Places and situations where non-smokers feel that they are exposed to smoking are at entrances and while waiting for public transport. According to the results the two groups supports introduction of special smoking places. The reasons for this may differ slightly between the groups, smokers want to smoke undisturbed and non-smokers do not want to be exposed to smoke. There is desire for a distance of at least 15 meters from the public building or public transport but it may as smokers express not be too far away. Smokers have limits on how far they should have to walk to smoke. They do not want to run from the special smoking place to catch the train / bus. The most interesting is that when it comes to non-smokers, is that they say they are exposed especially at large entrances and places where they are waiting for public transport, while this sites offer exactly what smokers want in terms of the design of special places for smoking. There are roofs, ashtrays and seating and there is nothing to prevent them from smoking there. The sites offer exactly what smokers believe well arranged smoking places are. / Pelle sellgren

Previous studies have found that smoking may have a negative effect on vitamin B-6 indices and have demonstrated a possible association between smoking and depressed plasma pyridoxal-5'-phosphate (PLP) concentration. Individuals with plasma PLP values below the adequate level of 30 nmoles/L might benefit from consumption of vitamin B-6 supplements, but no data are available on vitamin B-6 status in smokers consuming a controlled vitamin B-6 intake and receiving a vitamin B-6 supplement. The objectives of this research were to assess vitamin B-6 status in smokers as compared to non-smokers receiving a controlled diet and to evaluate the effect of an oral vitamin B-6 supplementation in these subjects. The vitamin B-6 (B-6) status of 5 (four males / one female) smokers (S) and 4 (three males / one female) non-smokers (NS) was assessed. A constant diet was fed for 20 days and provided 1.95 mg of B-6 or 1.65 mg of B-6 for males and females, respectively. For the last 10 days, an additional 2-mg of pyridoxine (PN) was given daily. Blood samples were collected on days 1.7, 11.14 and 21; and 24 hour urine samples were collected daily. Urinary 4-pyridoxic acid (4-PA) and total B-6 (UB6) excretion, plasma B-6 vitamers (PLP, PN, pyridoxal and 4-PA) and red blood cell PLP (RBC PLP) concentrations, as well as plasma alkaline phosphatase activity (APA) were determined. Mean plasma PLP, 4-PA, and RBC PLP concentrations were significantly lower (P [less than or equal to] 0.05) at all time points in S compared to NS. With a daily supplement of 2-mg vitamin B-6, the mean plasma PLP concentration of S increased 85.8% but was 48.5% lower than that of NS consuming 1.65-1.95 mg/d of B-6. Mean plasma pyridoxal concentrations were not different between S and NS before and after supplementation. Excretion of 4-PA was not significantly different between S and NS, but the mean values of 4-PA excretion were consistently greater in NS compared to that of S throughout the 20-day study. The percent of ingested B-6 excreted as 4-PA for the S and NS was 38 and 49 in the non-supplemented period, and 47 and 53 in the supplemented period, respectively, indicating that non-smokers excreted more 4-PA than smokers. However, the difference in 4-PA excretion between S and NS was not significantly different both before and after supplementation (P>0.05). In addition, there was no significant difference between S and NS for plasma PN concentration, AP, and UB6 excretion for both periods. Results suggested an adverse effect of smoking on B-6 metabolism, thus an increased requirement of vitamin B-6 in smokers. A 2-mg PN supplement was sufficient to bring the concentration of plasma PLP in smokers to the level suggested as adequate, but it didn't bring it to the level of non-smokers. / Graduation date: 1999
