Medical students' perceptions and attitudes to the role of doctors in tobacco control programmesMadiebo, Kenneth Chukwuka 04 November 2008 (has links)
Introduction: The deleterious health effects of tobacco use and smoking in
particular have been well documented. Anti-smoking campaigns have been in
existence for decades. Doctors, generally perceived as role models by members of
their societies, can play a significant role in anti-tobacco programmes.
Objectives: The objectives were: to determine the prevalence of tobacco use
among medical students, their knowledge of the health effects of tobacco use, their
beliefs and perceptions about anti-tobacco legislation/restrictions and the role of
doctors as advocates in tobacco-cessation programmes.
Methodology: A cross-sectional census was carried out using the 3rd and 5th year
students at the medical school of the University of the Witwatersrand (n = 357).
Results: The total prevalence of smoking was 15.4% (n = 53), with 9.6% (n = 34)
smoking occasionally and 6.2% (n = 22) smoking daily. Among the smokers, more of
the 3rd year students smoked daily compared to the 5th years (64% vs 19.3%, p =
0.001). Overall, there were no major differences between the sexes with respect to
prevalence of smoking (P= 0.312 Fischer exact test) across both classes. Within the
male population (Africans, whites and Asians) overall differences ( 2- אל 11.1, p=
0.006) existed in their smoking patterns. Both the whites and the Asians smoked
more than their African counterparts (5.8%, n = 3). There were however no
differences in the smoking prevalence rates between the whites and the Asians
((20.9% vs 31.6%: p= 0.314). The females differed (P = 0.042 Fischer exact test) in
their smoking behaviour across the races: Coloured (33.3%, n = 2), white (16.5%, n
= 18), Asian (13.3%, n =9) and Africans (4.0%, n = 2). The prevalence of noncigarette
tobacco use was 14%, with the majority smoking hookahs (7.1%, n=26).
More of the 5th year students than their 3rd year students counterparts (23.5% vs
7.1%) had very good knowledge of tobacco cessation techniques and overall
differences were observed ( 2אל -35.5, P <0.001). About 90% (n = 316) of the students
knew about the dangers of smoking, but 12% (n = 41) did not associate smoking
with heart disease. About 45% (n= 179) of the respondents believed that ban of
smoking in public space had reduced prevalence rates and about 40% (n= 172)
believed that taxation had reduced prevalence rates of tobacco use in South Africa.
Almost 50% (n= 164) students believed that the ban of tobacco sales to minors had
reduced prevalence rates and about 85% (n= 286) of the respondents agreed that
pictorial health warnings should be placed on the packages of tobacco products. The
students generally believed that doctors are seen as role models (84%, n= 286) by
society and should not smoke (86.3%, n= 299). Even though 81% (n= 279) of the
students were willing to speak to the community about the dangers of tobacco, only
about 30% (n= 101) were willing to be members in an anti-tobacco organisation.
Discussion and conclusion: The prevalence of smoking among the respondents
was lower than national prevalence rates among adults but similar to that of South
African young adults. The students had a low knowledge of tobacco cessation
techniques. Less than half of the respondents believed that the current anti-tobacco
legislation was effective and the majority supported the inclusion of pictorial
warnings on the packages of tobacco products. The majority of the participants
agreed that doctors were perceived as role models by members of their communities
and should not smoke. There was a general willingness on the part of the
respondents to advice their patients to quit smoking but majority of the participants
however would not want to get involved in anti-tobacco organisations in the future.

Philip Morris Faces "the truth": A Rhetorical Analysis of the Persuasiveness of Two Teen-Targeted Anti-Smoking Advertising CampaignsMcMurray, Marybeth 06 January 2003 (has links) (PDF)
This thesis examines the persuasiveness of anti-smoking television advertisements aimed at teens and produced by Philip Morris's Youth Smoking Prevention Program and the American Legacy Foundation's truth campaign. The advertisements are analyzed rhetorically using Kenneth Burke's dramatistic approach, supplemented by theory related to persuasive advertising, characteristics of at-risk adolescents, persuasive attack, and persuasive defense (apologia). The analysis indicates that strong central themes present in both the Philip Morris and truth campaigns act as a means of rhetorical persuasion, but are not necessarily rhetoric designed to persuade adolescents not to smoke cigarettes. The truth campaign advertisements contain both strengths and weaknesses. The weakness of the truth ads is related to an over-reliance on allegory-type scenarios meant to communicate anti-smoking sentiments and the theme of manipulation. Truth ads that contain clearer messages conveyed by appealing central characters are a more effective means of communicating not only an anti-smoking ideology, but also the theme of adolescent empowerment. This thesis's analysis more alarmingly indicates that the Philip Morris ads are in no way an effective means of smoking prevention. The Philip Morris campaign acts as a persuasive defense with the intended purpose of image repair and may encourage adolescents to think of Philip Morris and their tobacco products in a positive light. Conclusions suggest that due to the vast impact of media the glorifies smoking and other self-injurious behaviors; infrequent appearance of pro-social media appeals; insidious coercive tactics of the tobacco industry; possible limitations in determining the effectiveness of pro-social media appeals due to adolescent self-perception (or third person effect variables); and lack of attention paid to more vulnerable or at-risk youth, the real need may not be better pro-social media campaigns, but rather media literacy campaigns. In doing so, youth may become empowered, critical thinkers able to make life choices based on personal preference and the desire for self-fulfillment, instead of being coerced into a belief system induced by the bombardment of media.
