Interest in self-help materials among a general population sample of smokers.

Previous studies have shown that self-help materials can be effective in helping people quit smoking. However, it is not known what proportion of smokers in the general population are interested in this method of cessation. A representative sample of 267 daily smokers participated in a random digit dialing telephone survey. Respondents were asked about their level of interest in self-help materials that would help them quit smoking. Potential predictors of level of interest were examined first through bivariate analyses, followed by a multinomial logistic regression. Of daily smokers, 27% were very interested in receiving a self-help booklet, 28% were somewhat interested, and 45% were not at all interested. Interest in self-help materials was positively related to intent to quit in the next 6 months and to low family income.

Predictors of Canadian legislators' support for tobacco control policies.

It is clear that regulatory strategies can be effective in reducing tobacco use. Because legislators ultimately determine whether many of these policies are enacted, they are a key focus for tobacco policy research. This study identifies political and personal predictors of Canadian legislators' support for tobacco control policies. Data are from a 1996-97 survey of federal, provincial and territorial legislators. Multivariate regression analysis was used to assess relationships between five groups of variables (political factors including political ideology, personal characteristics, tobacco experiences, tobacco knowledge, interest group saliency) and support for tobacco control based on an 11-item scale. Support for tobacco control varied by political party. Support was higher among legislators who thought government had a duty to promote healthy lifestyles, knew second-hand smoke could cause lung cancer, knew tobacco caused more deaths than alcohol, and said they wanted more contact with medical associations about tobacco issues. Support was lower among current smokers and those with tobacco industry jobs in their ridings. The findings indicate that political party membership cannot be ignored in enlisting legislator support for tobacco control. It also appears that legislators who oppose tobacco control measures may not be opposed to tobacco control per se, but are more generally opposed to a government role in health promotion. Thus, public health professionals and tobacco control advocates need to be more attentive to the way tobacco control issues are framed for particular legislators. Further, meetings with health groups about tobacco issues would be welcomed by many legislators; non-governmental organizations and other health advocates could work to increase tobacco knowledge among legislators.

Effects of gender in social control of smoking cessation.

This study of 93 men and 117 women smokers during an ongoing quit attempt examined the roles of gender and social network influences on quitting. For men, social influences appeared to positively affect their ability to reduce their smoking but were less effective for women. Specifically, increased reports of a spouse or partner's influence, and family and friends' influence, were associated with greater reductions in men's smoking 2 days and 4 months post quit date, respectively. In contrast, for women, greater reports of spouse or partner influence and of family and friends' influence were associated with smaller reductions in smoking. Sex differences in social control strategies and perceived autonomy supportiveness of those strategies are discussed as possible explanations for these results.

Is 'stage of change' related to knowledge of health effects and support for tobacco control?

We examine the heterogeneity among current and former smokers categorized by 'stage of change' with respect to their perceptions about tobacco and tobacco control. Current and former smokers (n = 846) from a general population sample of adults in Ontario, Canada, were subdivided according to the stages of change categories (precontemplation, contemplation, preparation, action, maintenance, and termination) and compared on measures of knowledge, attitudes, and support. Multivariate analyses were conducted adjusting for sociodemographic covariates. Adjusted overall increases across the six stages were observed for seven of eight knowledge items and for all attitude and support items. Among current smokers, adjusted increases across the three stages were detected for a majority of items. However, statistically significant differences from one stage to the next, across all three current smoker stages, were detected only for one item. Among former smokers, adjusted increases across the three stages were observed for a minority of items. The stages of change classification was useful for differentiating subgroups of current smokers with regard to knowledge, attitudes, and support for tobacco control measures.

The relationship between body weight perceptions, weight control behaviours and smoking status among adolescents.

OBJECTIVES: This paper examines the relation between body weight perceptions, weight control behaviours and smoking status among a representative sample of Ontario students. METHODS: Bivariate and multivariate logistic regression analysis was used to evaluate the association between smoking status and perception of being overweight, and between smoking status and specific weight control behaviours. RESULTS: Among females, the odds of being a smoker were significantly higher among those who perceived themselves to be overweight and who had employed weight control behaviours in the last 12 months. Among males, the adjusted odds of being a smoker was higher only among those who skipped meals in the past 12 months. CONCLUSIONS: Body weight perceptions and the use of weight control behaviours were significantly associated with predictors of smoking among adolescent females. This suggests a need to incorporate discussion on body weight perception and body image in smoking prevention and cessation programs targeted toward adolescent females.

The early 1990s cigarette price decrease and trends in youth smoking in Ontario.

BACKGROUND: Youth are especially vulnerable to fluctuations in cigarette price, and both the smuggling increase during the early 1990s and the 1994 tax decrease made purchasing easier for youth. The purpose of this study is to examine the relation between these price decreases, and trends in smoking prevalence and amount smoked among Ontario youth. METHODS: Data from the Ontario Student Drug Use Survey were analyzed for trend using: 1) polynomial regression, and 2) discontinuity regression with an "event time" of 1993 to capture effects of both pre-tax cut smuggling and the tax cut. RESULTS: Overall, smoking prevalence decreased from 1977 to 1993, jumped upward at this time, and decreased after 1993. Among daily smokers, mean number of cigarettes smoked daily showed an increase followed by a decrease over the 24 years, and a negative quadratic trend. Trends for subgroups are also reported. CONCLUSIONS: These findings suggest that the early 1990s cigarette price decrease may have played a role in increasing youth smoking in Ontario.

Support for tobacco control policies: how congruent are the attitudes of legislators and the public?

OBJECTIVES: To examine the congruence in perceptions and attitudes of legislators and the public regarding tobacco and tobacco control policies. METHODS: Two cross-sectional surveys were used, one of elected federal and provincial legislators and one of adult residents in Ontario, Canada. Perceptions and attitudes were analyzed as dependent variables using multiple logistic regression, and adjusted for age, sex, educational attainment, and smoking status. FINDINGS: Congruence was found in most instances, however, some differences were found. Legislators were more likely than the public to agree that most smokers are addicted and were more supportive of a smoking ban in workplaces, but these differences disappeared after controlling for socio-demographic characteristics. Legislators were also more aware than the public of the magnitude of deaths due to tobacco compared to alcohol, whereas the public was more supportive of strong penalties against stores that sell cigarettes to minors. CONCLUSIONS: Our findings provide considerable evidence for congruence in the "real-world" (unadjusted) perceptions and attitudes of Ontario legislators and the Ontario public toward tobacco control policies. Such findings are positive for tobacco control advocates and should be leveraged to bring forward strong tobacco policies in the political arena.

Tobacco industry links to faculties of medicine in Canada.

BACKGROUND: The tobacco industry uses various strategies to promote itself as a socially responsible, ethical industry, including establishing links with health institutions and medical research. The purpose of this study was to identify the relationships between the tobacco industry and Canadian faculties of medicine, specifically research funding and donations from tobacco industry sources, and faculty-specific policies regarding the acceptance of tobacco industry funds. METHODS: Information about policies and practices regarding research funding and donations from 1996-1999 was requested from the 16 Canadian faculties of medicine and their parent universities, as part of a larger cross-sectional survey-centred study that examined links between the tobacco industry and Canadian universities. RESULTS: All 16 faculties of medicine (100%) reported on research funding and 11/16 (70%) reported on donations from the tobacco industry. Twenty-five percent (4/16) of the faculties received research funding from the tobacco industry and 27% (3/11) received donations. No Canadian medical school had a policy that banned tobacco industry research funding or donations. INTERPRETATION: The tobacco industry have made donations and given research funding to faculties of medicine in Canada. This may present major conflicts of interest that undermine public health and have implications for the scientific integrity of the medical research enterprise. Faculties of medicine should consider developing policies that prohibit tobacco industry research funding and donations, with the intent of preventing conflicts and precluding ethical dilemmas arising from links with the tobacco industry. They should also encourage parent universities to establish similar policies at an institutional level.
