Smoking control in the workplace: is workplace size related to restrictions and programs?

Regarding smoking control in the workplace, small independent operations may differ from large workplaces or from small worksites that are branch units of large companies/organizations. We examined the relationships of worksite and company size to workplace smoking restrictions and programs, using data from a population-based telephone survey. Three worker groups, differentiated by worksite and company size, were compared. Small workplace workers were least knowledgeable about smoking restrictions, reported fewer restrictions in place, and were least willing to intervene in coworkers' smoking. As well, smoking-related programs, although generally uncommon, were reported least often by these workers. Branch workers were not uniformly similar to either small or large workplace workers. In policy and program interventions, organizational influences and/or attributes of individuals drawn to different-size work settings should be considered.

Moderate drinking and health. Implications of recent evidence.

OBJECTIVE: To address three questions (Is moderate drinking good for health? Should people drink to prevent heart disease? What is moderate drinking?) and to examine and compare two recent Canadian guidelines on low-risk drinking in the context of counseling patients. DATA SOURCES: English-language data sources were searched, particularly peer-reviewed health and social science literature and recent expert reports. STUDY SELECTION: Studies and reports were selected for their scientific merit and direct relevance to the three questions addressed and to the formulation of guidelines on low-risk drinking. SYNTHESIS: While moderate drinking might protect some older people against coronary heart disease, it is associated with increased risk of hemorrhagic stroke, certain cancers, accidents and injuries, and a range of social problems. For most health outcomes, risk increases as consumption of alcohol increases. CONCLUSIONS: While the data have limitations, they provide a basis for formulating guidelines on low-risk drinking. The two Canadian guidelines, one developed from the perspective of health recovery, the other from the perspective of health promotion, complement each other in the context of counseling patients.

Alcohol and health: individual and population perspectives.

This paper summarizes the relationships between alcohol consumption and health from both the individual and the population perspectives. On the individual level adverse consequences of alcohol consumption on mortality, morbidity and social harm are summarized. The potential health benefits of drinking are listed next, especially in the context of trying to balance positive and negative consequences. Even though the final decision rests with the individual it is suggested that from a health perspective light drinking on a regular basis is most advisable. In terms of advice to populations it should be noted that, due to the mutual interdependence of drinking behaviour in a society, the average individual consumption associated with the lowest individual risk is not necessarily the average per capita consumption associated with the lowest population risk. Thus, research at the population level has to be integrated with individual epidemiological research in order to come up with the best advice for the population in any given society.

Feasibility of the neuropsychological spectrum in prediction of outcome following head injury.

This study provided further substantiation of the neuropsychological spectrum conceptualization (Templer, Campodonico, Trent, Spencer, & Hartlage, to appear; Templer, Spencer, & Hartlage, 1993; Templer, Campodonico, Trent, & Spencer, 1991). Two hundred and two traumatic brain injury patients were administered the Wechsler Adult Intelligence Scale-Revised, the Luria-Nebraska Neuropsychological Battery, the Wisconsin Card Sorting Test, the Booklet Category Test, and Trails A and B. The correlations between neuropsychological and intellectual tests were significantly lower than the correlations within intelligence tests and within neuropsychological tests. Neuropsychological tests predicted outcome better than intelligence tests. This was interpreted in terms of outcome for severely brain-damaged patients being more dependent upon basic neuropsychological functioning than on abstract thinking ability.

Smoking in the workplace: do smoking patterns and attitudes reflect the legislative environment?

OBJECTIVE: With regard to the workplace, to examine restrictions on smoking, smoking at work, attitudes toward and reactions to restrictions, and workplace programmes in the context of the legislative environment. DESIGN: Population-based telephone interview survey of adult residents of the jurisdictions of Metropolitan Toronto, Ontario, Canada. SUBJECTS: Workers within the City of Toronto (n = 374) were compared with other workers (n = 536), because their legislative environments with regard to workplace smoking were markedly different, with workplaces in the City of Toronto being covered by a much more stringent bylaw. RESULTS: In comparison with other workers, City of Toronto workers reported workplace restrictions to be more common and widespread. These workers were also less likely to smoke at work, and more likely to smoke less at work and to have cut down on smoking at work. Quit-smoking rates, however, were similar. There was evidence of some compensatory smoking outside work, but additional compensation in association with more stringent restrictions was not found. City workers and other workers were similar in their support for smoke-free workplaces, in their attitudes to the role of governments in regulating workplace smoking, and in their perceptions of conflict between smokers and non-smokers. Reports of quit-smoking programmes and educational interventions in the workplace were similarly uncommon, although both groups of workers indicated strong support for the role of business and industry in helping people quit. CONCLUSIONS: Restrictions on smoking and smoking patterns reflected the legislative environment; a more stringent environment was associated with more restrictions and less smoking at work.

Quitting smoking: why, how, and what might help.

OBJECTIVE: To examine reasons for quitting smoking, methods used in quitting, reasons for continuing smoking and potential aids to quitting in the population of Ontario, Canada. DESIGN: Two population-based, telephone interview surveys, conducted by random-digit dialing. SUBJECTS: Adults aged 18 years of age and older in 1983 (n = 1383) and 1991 (n = 1421). MAIN OUTCOME MEASURES: Information was obtained from former smokers on why and how they quit smoking, and from continuing smokers on why they smoked and what might help them quit. RESULTS: The proportion of current smokers in the population decreased from 35.5% in 1983 to 27.2% in 1991. In both surveys, former smokers cited a variety of reasons for quitting, including personal health concerns, social and environmental factors, personal attitude factors, cost, and health education messages. Responses concerning the most important reason also revealed a range of factors; "advice of a physician" was not prominent among them. When questioned about methods used in quitting, most former smokers in both surveys responded that they "just decided to quit". Very few reported using other aids such as cessation clinics or nicotine gum. More smokers in 1991 than in 1983 reported that they continued smoking for enjoyment, to satisfy a craving or addiction, and for relaxation. With regard to what might help them quit, continuing smokers in both surveys cited a wide variety of potential aids, including information on harmful effects, more restrictions on smoking and on sales, cessation clinics, programmes on radio/TV, and higher taxes. CONCLUSIONS: These findings support a multifaceted approach to tobacco control.

On the emerging paradigm of drinking patterns and their social and health consequences.

Recent epidemiological and social studies have increasingly pointed to the importance of drinking patterns in explaining consequences of alcohol consumption. This paper presents recommendations for research in the area based on the presentations and discussions of the first "International Conference on Social and Health Effects of Different Drinking Patterns" held in Toronto in November 1995. In particular, the social dimension in pattern research, and the relationship between patterns of drinking and casualties as well as social harm, are stressed. The paper also argues for better theories, incorporating knowledge from related basic disciplines. In addition, we emphasize the need for improved methodologies and standardized methods for assessing drinking patterns. Finally, implications of research on drinking patterns for policy and programme development are discussed.

Post-acute rehabilitation outcome: relationship to case-management techniques and strategy.

Successful outcome for the traumatically brain-injured (TBI) patient is dependent on both a productive clinical therapy program and an effective case-management strategy by the carrier. This retrospective study focuses on identifying those case-management techniques which contributed to improvement in the disability, living, and occupational status of patients in a post-acute rehabilitation program. Statistical analysis indicated a positive relationship between two case-management factors and improved patient outcome. Additional analysis demonstrated predictive qualities of specific admission data for patient program cost. A review of these case-management techniques and their impact on discharge disability, living, and occupational status will be discussed.

Restrictions on smoking: growth in population support between 1983 and 1991 in Ontario, Canada.

While much progress in curtailing exposure to environmental tobacco smoke has occurred in Ontario, many jurisdictions still do not have any restrictions on smoking. To assess support in Ontario for restrictions, and recent changes in knowledge, attitudes, and behavior, we compared the findings of a population-based telephone survey conducted in 1991 (n = 1421) to those of a similar survey conducted in 1983 (n = 1383). Increases were found in the population's reported knowledge of specific health effects. Marked changes occurred in attitudes to restrictions on smoking. In 1991, the population consistently favoured more restrictions on smoking and their enactment by all levels of government. A role for local health departments in enforcement was clearly recognized. Most smokers indicated that they would comply with more restrictions. We also found that the self-reported prevalence of smoking had decreased 8 percentage points between 1983 and 1991. Population-based evidence of strong and increasing support for restrictions, accompanied by predictions of a high level of compliance, especially by smokers themselves, should facilitate legislation aimed at further curtailing smoking.

An evaluation of the workplace smoking bylaw in the city of Toronto.

Random-digit dialing surveys were conducted before (n = 1543) and 8 to 9 months after (n = 1430) implementation of the city of Toronto workplace smoking bylaw. Compared with workers in the rest of metropolitan Toronto and persons not working outside the home, city workers evidenced more positive changes in regard to knowledge of the bylaw, its requirements, and enforcement provisions. City workers reported more changes in workplace restrictions and satisfaction with such restrictions. Patterns of smoking at work changed.

Embryological considerations of distinctive feature theory.

The role of the physiology is emphasized here, perhaps to the eventual denial of the importance of the acoustic cues involved at these stages. The acoustic cues are the result of the physiology and are a further development of the features of speech. The selection of the sounds of babbling is a function of the physiological readiness and is an internal function [Locke, 1983]. Sounds are produced that are not used in final adult speech [Locke, 1983]. It is the acoustic cues of the environment that perhaps cause the 'babbling drift' toward adult speech of the environment [Brown, 1958]. In line with the above-mentioned ideas regarding branchial arch development, most of the components of the outer and middle ear are derivatives of the first branchial arch, which though limited musculature is involved, especially for sound perception, might downplay the role of acoustics at these earliest stages even further. If it can be said that cortical organization and representation development follow a similar sequence as is evidenced from the branchial arches and their derivatives, the importance of acoustic stimuli, at this point, would be even further questioned for these early stages. The assumption should be made that a muscle or muscle group does not function prior to this established branchial arch pair sequence. The major distinction here has been utilization of the structures in a 'conscious', deliberate, voluntary manner with a specific goal in mind. The babbling and even feeding that children undergo provides evidence that these structures function perhaps long before any sequence of branchial arch pair developmental sequence can be applied.(ABSTRACT TRUNCATED AT 250 WORDS)

Preventing alcohol problems: survey of Canadian medical schools.

In preparation for a national conference on medical education in the prevention of alcohol problems, a survey of conference participants was conducted. Participants were undergraduate and postgraduate representatives from each Canadian medical school and representatives from 11 provincial and territorial alcohol and other drug agencies. There was agreement that physicians and medical schools have important roles in prevention and treatment of alcohol problems, with "traditional" medical roles seen as the most important. Current training is variable and was seen as inadequate, with more time devoted to treatment than prevention. To correct this situation, renewed priorities and faculty leadership are needed. Respondents felt that there should be uniform standards for assessing undergraduate students' skills in dealing with alcohol problems. Provincial alcohol and other drug agencies are underused in medical education in the prevention and treatment of alcohol problems.

Intensity of follow-up. Effects on estimates in a population telephone survey with an extension of Kish's (1965) approach.

Information from a population telephone survey of attitudes of residents of the Province of Ontario, Canada, toward legislation to restrict smoking was used to examine the effects of intensity of follow-up on population estimates. It was found that the bias introduced to the attitude estimates by less intensive follow-up was smaller than the bias introduced to estimates of sociodemographic characteristics and smoking status. An algebraic determination of the components contributing to the bias in the attitude estimates was used to investigate how the relation between smoking status and certain attitudes influenced the relation between attitude and intensity of follow-up. This required an extension of the approach described by Kish (Survey Sampling. New York: John Wiley and Sons, 1965.)
