A population survey on legislative measures to restrict smoking in Ontario: 3. Variables related to attitudes of smokers and nonsmokers.

A telephone survey of 1,383 residents of Ontario was conducted to assess attitudes toward antismoking legislation and knowledge of active and passive smoking health effects. After estimation of population parameters, analyses were carried out separately in smokers and nonsmokers to determine which characteristics, if any, were related to positive and negative attitudes, higher or lower knowledge scores, and predicted compliance or noncompliance with restrictive measures. Both bivariate and multivariate analyses were carried out. This paper reports the results for several measures of attitudes including restrictions on smoking locations and sales, differential insurance rates, control of advertising, and increase in taxes on cigarettes. Identification of smokers who hold negative attitudes is more reliable than identification of nonsmokers who hold positive views. Because different sets of variables were found to be related for the different attitude measures, it may be necessary to design different kinds of programs to prepare individuals for changes in legislation. The companion paper on p. 323 reports on the results for knowledge of active and passive smoking health effects and predicted compliance.

A population survey on legislative measures to restrict smoking in Ontario: 4. Variables related to knowledge of active and passive smoking health effects and to predicted behavior of smokers and nonsmokers.

Results from the further analysis of a population survey on legislative measures to restrict smoking revealed that identification of subgroups of smokers is more reliable than identification of subgroups of nonsmokers when a variety of attitudes were the measures of interest. A similar pattern emerged when analyses were carried out on knowledge of active and passive smoking health effects and on predicted personal and general compliance. Because distinct sets of variables were found to be related to distinct outcomes, program planning for changes in knowledge and behavior might, of necessity, have to be different. Media messages might be useful for changes in knowledge, while actual experience might be more important for attitude and behavior change.

Chronic eosinophilic pneumonia. Diagnosis by fine needle aspiration.

A case of chronic eosinophilic pneumonia in which the diagnosis was established by fine needle aspiration of the pulmonary lesions is presented. The cytologic findings included the presence of an inflammatory exudate consisting of 40% eosinophils, 25% neutrophils and the remaining cells comprised of lymphocytes, histiocytes, atypical columnar cells and cells probably of pneumocyte type II origin. Fine needle aspiration of pulmonary infiltrates can be quite helpful in confirming the diagnosis of chronic eosinophilic pneumonia and in differentiating it from other similar conditions including malignant lymphomas, if the clinical and radiologic appearances are also taken into consideration.

A population survey on legislative measures to restrict smoking in Ontario: 1. Design, methodology, and sample representativeness.

Legislative measures restricting cigarette smoking have the potential to influence whether a person begins or continues to smoke and to affect the impact of passive smoking. We surveyed a representative sample of the adult population in Ontario on their knowledge of existing legislation and of the adverse effects of primary and secondary smoking on health. We also assessed their attitudes toward a range of restrictions and changes in legislation as well as their views on the enactment and enforcement of such legislation. This paper reports on the sample design, methods, response rates, and representativeness of the respondents. We used a three-stage stratified cluster design, covering both urban areas (with or without existing smoking bylaws) and rural areas and incorporating telephone interviews using random-digit dialing. The total number of respondents was 1,383, for an overall response rate of 67.5 percent. Despite attempts to ensure anonymity and to convey the importance of participation, we did not achieve total representativeness in sex ratio, age distribution, and certain educational and occupational categories. A companion paper reports on the population estimates of the variables under study.

A population survey on legislative measures to restrict smoking in Ontario: 2. Knowledge, attitudes, and predicted behavior.

From the results of a population survey (n = 1,383) in the province of Ontario on legislative measures to restrict cigarette smoking we conclude that more is known about the adverse effects of active smoking than about those of passive smoking. Most people supported some degree of restriction in 13 specified locations. A majority supported total bans on smoking in day care and health-related facilities. Most respondents thought municipal governments should be responsible for legislating such bans and owner/managers responsible for enforcing them. However, there were a variety of opinions on the effectiveness of legislation in helping people to quit smoking. Responses differed slightly according to the geographic locations of the respondents, with residents of urban areas with bylaws being more restrictive. We suggest that such opinions and attitudes be studied further before legislative measures are enacted, so that all segments of the population are satisfied and unnecessary conflicts can be avoided.
