Durability, dissemination, and institutionalization of worksite tobacco control programs: results from the Working Well trial.

Durability, dissemination and institutionalization o f tobacco control activities are reported, based on the Working Well worksite cancer control intervention study (n = 83 worksites). Tobacco control activities increased significantly in intervention worksites as a result of research-supported activities but were not sustained 2 years after the conclusion of the intervention. Intervention sites were more likely than control sites to initiate and maintain structures for institutionalizing programs, such as assigning a committee responsibility for health-promotion programs or providing a budget for health-promoting activities. Dissemination of the program to control worksites had little impact on the level of smoking control activities in control worksites. Although program durability was not a primary aim of this intervention study, these analyses provide an important assessment of program maintenance beyond a funded intervention and underscore the need for additional research to identify effective organizational strategies for institutionalization of worksite health-promotion programs.

Reactions of adult and teenaged smokers to the Massachusetts tobacco tax.

OBJECTIVES: This study assessed smokers' reactions to a 25 cents cigarette tax imposed in Massachusetts. METHODS: A statewide telephone survey of 1783 adult smokers and 216 teenaged smokers was conducted. RESULTS: Among adult smokers, 3.5% reported that they had stopped smoking, owing in part to the price increase; 35% had considered quitting and 19% had attempted to cut the cost of smoking by switching to cheaper brands or cutting down. Among teenagers, 21% had considered quitting and 26% had cut costs. Low-income smokers were more responsive to the price increase than more affluent smokers. CONCLUSIONS: A modest and temporary price increase promoted quitting among adult smokers and reduced cigarette consumption among low-income teenagers.

Do physicians do what they say? The inclination to test and its association with coronary angiography rates.

OBJECTIVE: Efforts to evaluate variations in cardiac procedures have focused on patient factors and differences in health care delivery systems. We wanted to assess how physicians' inclination to test patients with coronary artery disease influences utilization patterns. SETTING AND SUBJECTS: Physicians and the populations of Maine, New Hampshire, and Vermont. DESIGN: We conducted a survey of 263 family practitioners, internists, and cardiologists residing in 57 hospital service areas in Maine, New Hampshire, and Vermont. Using patient scenarios, we assessed the clinicians' inclinations to test during the evaluation of patients with coronary artery disease. Self-reported testing intensities were used to create three indices: a Catheterization Index, an Imaging Exercise Tolerance Test (ETT) Index, and Nonimaging ETT Index. Using administrative data, age- and gender-adjusted population-based coronary angiography rates were calculated. Physicians were assigned to low (2.9/1,000), average (4.2/1,000), and high (5.8/1,000) coronary angiography rate areas, based on where they practice. Analysis of variance techniques were used to assess the relation of the index scores to the population-based coronary angiography rates and to physician specialties. RESULTS: There was a positive relationship between the population-based coronary angiography rates and the self-reported scores of the Catheterization Index (p < .005) and the Imaging ETT Index (p = .01), but none was found for the Non-imaging ETT Index (p = .10). These relationships were evident in subanalyses of cardiologists and internists, but not of family practitioners. CONCLUSIONS: Self-reported testing intensity by physicians is related to the population-based rates of coronary angiography. This relationship cuts across specialties, suggesting that there is a "medical signature" for the evaluation of patients with coronary artery disease.

Behavior intentions of the public after bans on smoking in restaurants and bars.

OBJECTIVES: This study assessed the potential effect of smoke-free policies on bar and restaurant patronage. METHODS: Random-digit dialing techniques were used in surveying a representative sample of Massachusetts adults (n = 2356) by telephone. RESULTS: Approximately 61% of the respondents predicted no change in their use of restaurants in response to smoke-free policies, 30% predicted increased use, and 8% predicted decreased use. In turn, 69% of the respondents predicted no change in their patronage of bars, while 20% predicted increased use and 11% predicted decreased use. CONCLUSIONS: These results suggest that smoke-free policies are likely to increase overall patronage of bars and restaurants.

The Working Well Trial: baseline dietary and smoking behaviors of employees and related worksite characteristics. The Working Well Research Group.

BACKGROUND: The Working Well Trial, the largest randomized worksite health promotion trial to date, tests the effects of cancer prevention and control interventions on dietary and smoking behaviors of employees and the worksite environment. The trial is a 5-year cooperative agreement conducted in 57 matched pairs of worksites in 16 states by four study centers, a coordinating center, and the National Cancer Institute. The dual aims of this paper are to: (a) present a baseline description of the dietary and smoking habits of 20,801 employees, who are predominantly blue-collar workers; and (b) describe the social and physical environments of their worksites that may facilitate or hinder health behavior changes. METHODS: The self-administered baseline survey of individuals consisted of a core set of questions common across all study centers on diet and smoking. The organizational survey consisted of eight instruments administered via interviews with key informants in each worksite. Continuous variable were analyzed by a mixed linear model and binary data were analyzed by the Generalized Estimating Equation. RESULTS: The population represented is largely male (67.5%) and blue collar (53.5%). Mean levels of fat and fiber intakes were close to the national averages (36.6% of calories as fat and 13.1 g of fiber). Smoking prevalence (25.2%) was slightly lower than the national average. The worksites had a high level of health promotion activities (42% had nutrition programs, 53% had smoking control programs), but lacked environmental support for dietary behavior change and perceived support for smoking cessation. CONCLUSIONS: These findings replicate and extend previous research results to a large sample of diverse, largely blue-collar worksites. In addition the baseline results lay a foundation for the development of new insights into the relationship between individual and organizational level variables that may interact to influence behavioral and cultural norms.

Women dieters of normal weight: their motives, goals, and risks.

Using data from a national survey of weight loss practices, this study examined those dieters who were of normal weight. Forty-seven percent of White women, 25% of Black women, and 16% of men currently trying to lose weight had a body mass index under 25. Women's primary motive was health improvement. Among normal-weight female dieters, 12% of Whites and 27% of Blacks were using risky strategies. Dieters were less likely than nondieters to smoke and reported better nutritional practices; however, they were not more likely to exercise, and their maximum weight fluctuation was 50% greater. Additional research on the consequences of dieting among normal-weight individuals is of high priority.

Recruitment of work sites to a health promotion research trial. Implications for generalizability.

The characteristics of companies that either accepted or declined participation in a 5-year randomized trial of a multirisk factor health promotion intervention were compared to investigate potential limitations on the generalizability of research findings. A representative sample of 151 manufacturing work sites in the northeast was recruited to participate. Sixty-four of the companies were determined to be eligible and 10 others, which refused to have an administrator interviewed, were presumed to be eligible. Of this group, 27 companies agreed to participate. Work force demographics, shift structure, and prior history of health promotion offerings were not significantly different in the two groups. However, participating companies employed fewer workers and had a more favorable financial outlook than did companies that declined to participate. Implications of these findings for research on work site health promotion are discussed.

Motivational characteristics of smokers at the workplace: a public health challenge.

BACKGROUND: Few studies have focused on the motivational characteristics of smokers who do not volunteer for cessation. This study examined the relationship between demographic and selected psychosocial factors and motivation and intention to quit smoking among employed smokers at five worksites. In addition, the distributions of smokers who are at different stages of readiness to change their smoking behavior are presented. RESULTS: Results indicate that, overall, less than 8% of employed smokers are currently ready to quit smoking and that blue-collar workers are lower in motivation than white-collar workers. Predictors of higher levels of motivation to quit smoking included higher socio-economic status, maleness, lower levels of self-reported nicotine dependence, and stronger perceptions that smoking was against the social norms of the workplace. CONCLUSION: Implications for intervention, evaluation, and policy are discussed in the context of the challenge of making a public health impact on reducing overall smoking prevalence.

The Contemplation Ladder: validation of a measure of readiness to consider smoking cessation.

Presents evidence for the validity of the Contemplation Ladder, a measure of readiness to consider smoking cessation. Analyses of data collected from more than 400 smokers at two worksites before and during a 10-month intervention indicate that Ladder scores were significantly associated with reported intention to quit, number of previous quit attempts, perceived co-worker encouragement to quit, and socioeconomic status. Ladder scores predicted subsequent participation in programs designed to educate workers about their smoking habit and its contingent risks. The Ladder did not predict biochemically validated abstinence of 24 hr or more. To assess its ability to distinguish between groups known a priori to differ in readiness, we administered the Ladder to 36 participants in a clinic-based smoking cessation program. As predicted, clinic patients scored significantly higher than the workers on the Ladder. The importance of distinguishing between smokers at the lowest stages of readiness to quit is discussed.

Debunking myths about self-quitting. Evidence from 10 prospective studies of persons who attempt to quit smoking by themselves.

This article examines data from 10 longterm prospective studies (N greater than 5,000) in relation to key issues about the self-quitting of smoking, especially those discussed by Schachter. When a single attempt to quit was evaluated, self-quitters' success rates were no better than those reported for formal treatment programs. Light smokers (20 or less cigarettes per day) were 2.2 times more likely to quit than heavy smokers. The cyclical nature of quitting was also examined. There was a moderate rate (mdn = 2.7%) of long-term quitting initiated after the early months (expected quitting window) of these studies, but also a high rate (mdn = 24%) of relapsing for persons abstinent for six months. The number of previous unsuccessful quit attempts was unrelated to success in quitting. Finally, there were few occasional smokers (slips) among successful long-term quitters. We argue that quitting smoking is a dynamic process, not a discrete event.

A comparative evaluation of a restrictive smoking policy in a general hospital.

The impact of a restrictive smoking policy on the behavior and attitudes of smokers and non-smokers was assessed by surveying random cross-sectional samples of hospital employees before, six months after and 12 months after the policy was implemented, and comparing responses with those of employees of a hospital with no restrictive policy. Effectiveness of policy implementation was also evaluated. Results indicated that the policy was well-publicized and was approved by virtually all the non-smokers and the majority of the smokers. Following implementation, employees in the smoking policy hospital were less likely to report being bothered by smoke at their work stations than were employees of the comparison hospital. Six months and one year after the policy change, smokers reported lower smoking rates while at work, although quit smoking rates and home smoking rates were similar in both hospitals.

Evaluating worksite smoking policies. Methodologic issues.

This paper discusses the methodologic issues one confronts when studying the impact of worksite smoking policies, using one such study as an example. Topics covered include defining the research questions, deciding on timing of measurements in relation to policy implementation, advantages and disadvantages of cohort versus cross-sectional research designs, and alternative measurement techniques. The sample study examined changes over one year in the smoking-related behaviors and attitudes of employees of a hospital that initiated a restrictive smoking policy, in relation to employees of a comparable hospital without a restrictive policy. The short term impact on ambient carbon monoxide was also examined. A case is made for studying the impact of smoking policy in the context of other strategies for reducing smoking prevalence at the worksite, such as individual treatment and organizational initiatives to motivate smoking cessation.

Determinants of physicians' preferences for alternative treatments in women with early breast cancer.

To learn about factors, that influence a physician's decision making, a mail survey was conducted asking physicians about their preferences for radical mastectomy vs. local excision plus irradiation, and for adjuvant chemotherapy vs. no adjuvant treatment for two hypothetical women with operable, clinical stage I breast cancer - one 35 years old and the other 60 years old. Two hundred and sixty-one physicians from varied specialties in Connecticut and Massachusetts returned the questionnaire. Approximately half of the respondents would accept either mastectomy or limited surgery plus radiation therapy for either patient. Adjuvant chemotherapy was recommended by 97% of respondents for the younger patient and by 66% for the older patient. Several factors appeared to be related to therapeutic preferences. An individual physician's attitude towards patient involvement in decision making was the most important predictor of surgical preference for both the patients, whereas the role of specialty (i.e., surgeons vs. other providers) was more important for the surgical management of the older patient. For the decision involving adjuvant chemotherapy, specialty, hospital size, and presence of radiotherapy equipment on site were important predictors. Factors other than survival (such as disease-free interval and cosmetic results) were viewed as important standards of effectiveness by some physicians.

Saliva cotinine as a measure of smoking status in field settings.

The accuracy and reliability of saliva cotinine as an objective measure of smoking status was examined in two field studies. In Study I, saliva was collected from smokers and nonsmokers with repeated samples taken from a randomly selected subset of the smokers. Results indicated perfect classification of smokers versus nonsmokers and acceptable reliability of repeated samples. Study II investigated the accuracy of saliva cotinine in detecting recent quitters in a worksite smoking cessation program. Saliva cotinine showed greater accuracy than expired carbon monoxide at detecting quitters, provided they were abstinent for at least seven days. From pre- to post-treatment, subject's saliva cotinine levels dropped 19 per cent while self-reported rate of smoking dropped 54 per cent. Saliva collection in the field is feasible and cotinine appears to be one of the more sensitive assays currently available for epidemiologic and clinical applications.

Household smoking restrictions and adolescents' exposure to environmental tobacco smoke.

BACKGROUND: Reducing adolescents' exposure to environmental tobacco smoke (ETS) is an important public health goal. This paper identifies the linkage between young people's exposure at home and household smoking restrictions, and suggests the promotion of such restrictions as a strategy to reduce health risks. METHODS: Data are from the 1993 Massachusetts Tobacco Survey, a telephone survey of 1,606 adolescents. RESULTS: Seventy-eight percent of adolescents reported exposure to ETS during the preceding week. Reported hours of exposure at home were associated with the number of adult smokers in the household (P < 0.001). Fifty-three percent of teens who lived with smokers reported no smoking restrictions for family members, 22% reported designated smoking areas, and 25% reported smoking bans. Among those households, smoking restrictions for family members were associated with significant reductions in mean hours of ETS exposure reported: no restrictions were associated with 33.2 hr of exposure during the prior week, designated smoking areas--12.7 hr, and household smoking bans--2.4 hr. Restrictions on visitor smoking were associated with significant reductions in home ETS exposure for teens who lived with nonsmokers, but had no independent effect among teens who lived with smokers. CONCLUSIONS: Health risks experienced by adolescents living with adult smokers can be substantially reduced by household smoking restrictions.
