The patterns of cigarette smoking and beliefs, attitudes and opinions about smoking among technikon students

Oberholster, Leon Eduard 04 June 2014 (has links)
M.Tech. (Environmental Health) / Although evidence of the hazards of cigarette smoking has been in existence for many decades, millions of people around the world are still smoking, hundreds of thousands of teenagers take up smoking and the tobacco companies are allowed to continue promoting their products. To the annoyance of non-smokers, smoking is still allowed in many public places, such as restaurants and offices. This study serves, firstly, to provide an overview of the results of research on the dangers of smoking, nicotine addiction and passive smoking. Secondly, a self-completion questionnaire has been applied to a sample of students at eight technikons in South Africa. The questionnaire was designed to investigate the prevalence of smoking among the different population groups and genders to reveal some of the pattems of smoking of students, the factors influencing students' smoking status and to test students' beliefs, opinions and attitudes regarding smoking. The third objective of the study is to develop a theory on cigarette smoking and to propose anti-smoking measures at technikons. Researchers have produced conclusive proof that cigarette smoking is the cause of cancer, respiratory and heart disease and other diseases. Smoking maims and kills millions of people around the world annually and threatens the health of unborn babies and non-smokers, especially children. Tobacco companies apply the most sophisticated promotion techniques to persuade people to smoke and teenagers and certain other sectors' of the population are targeted by these activities. A study of nicotine addiction reveals that the need for this substance becomes as strong as any of man's basic physiological needs, such as those for food and water. This makes it very difficult, if not impossible, for many smokers to give up smoking. A multi-pronged strategy to combat smoking at education institutions is proposed, which includes health education and the banning of smoking on campuses.

Evaluating Student Pharmacists’ Comfort Level and Effectiveness in Referring Tobacco Users to a Quit Line During Health Screening Events: A Pilot Study at One University

Babico, Mary, Lundeen, Emily, Spencer, Jenene January 2012 (has links)
Class of 2012 Abstract / Specific Aims: To assess the number of patients referred to ASHLine during the health screenings performed by University of Arizona College of Pharmacy students; and to identify the comfort level of students who asked patients about their smoking status. Methods: An anonymous questionnaire was sent via electronic mail to evaluate students’ comfort levels in implementing a smoking cessation referral program and subject demographics. Chart reviews quantified the number of patients referred to a smoking cessation program. Main Results: A total of 1,147 patients were screened for smoking cessation, 85 of which said they still smoked. Of the 85 who smoked, only 2 (0.17%) were referred to ASHLine. There was no significant increase in the comfort level of students (based on three domains) who participated in a smoking cessation training program or students in different years of their professional education. It was found that more students were comfortable with completing the required smoking cessation paperwork if they attended three or more health fairs (P=0.014). Conclusions: The comfort level of students with smoking cessation education is independent of the number of patients referred to a local smoking cessation program.

Psychological barriers to the modification of addictive smoking

Barnes, Scott Donovan 29 October 2008 (has links)
M.A. / The aim of this study was to investigate the psychological barriers to the cessation of smoking behaviour as experienced by addictive smokers in a South African context, and also to assess the relative importance of these barriers. These barriers were viewed as arising from perceptions of the costs and benefits or pros and cons of smoking and smoking cessation. This cognitive appraisal process was understood as being a series of schema for comprehending both the cognitive and motivational aspects of human planning for future action. The transtheoretical or stages of change model was used as a theoretical framework upon which the research was constructed. The model holds that two interrelated dimensions are necessary in order to adequately assess the behaviour modification of smoking and other such health compromising behaviours: stages of change and processes of change. Stages of change refer to the temporal, motivational, and constancy aspects of change while processes of change focus on activities and events that facilitate successful modification of a problem behaviour such as smoking, and represent coping activities used to modify smoking behaviour. The study hypothesized firstly that precontemplative smokers would demonstrate the highest ratings on the risks of smoking cessation and the lowest ratings on the benefits, while smokers in the contemplation stage would demonstrate a greater balance of risks and benefits of smoking cessation and smokers in the preparation stage would demonstrate highest ratings on the benefits of smoking cessation and the lowest ratings on the risks. In this way the study assessed the validity of various stages of change research in a South African context regarding the weighing up of the pros and cons of smoking behaviour and the expected linear shift in perceptions as the action stage is approached. However, for the purposes of the research conducted, the contemplation and preparation stages were combined to form what was referred to as the planning stage. Secondly, the study hypothesized that at each of the various stages, certain perceptions of the risks and benefits of smoking cessation would emerge as being of greater significance than others. A positivist approach to theory and investigation was utilized for the purposes of conducting the research. In accordance with this approach, quantitative self report data was collected. The Perceived Risks and Benefits Questionnaire was used as a means of assessing the perceived risks and benefits associated with smoking cessation. The results of this study demonstrated that stages of change did indeed have an effect on the way in which the risks and benefits of smoking cessation were perceived. In this regard, the variations between the various stages were in accordance with the findings of prior stages of change research. Certain risks and benefits also emerged as being of greater significance than others for smokers in the various stages. Results also underlined the importance taking a smokers stage of change of change into account when considering smoking cessation programmes. Processes of change as identified within the transtheoretical model emerged here as having a potentially important role to play, but more research investigating the matching of stages and processes of change in a South African context is required. In addition, it is also recommended that future research in this area be conducted within a variety of demographic and socio-economic contexts in South Africa. Research that is longitudinal in nature is also viewed as being potentially beneficial, as is research of a qualitative nature. Such investigations are viewed as important because they would continue to enrich our understanding of the journey towards smoking cessation as experienced by South African smokers. / Dr. Hilton Rudnick
