Abstract
BACKGROUND The average level of blood cholesterol is an important determinant of the risk of coronary heart disease. Blood cholesterol can be reduced by dietary means. Although dietitians are trained to provide dietary advice, for practical reasons it is also given by other health professionals and occasionally through the use of self-help resources. OBJECTIVES To assess the effects of dietary advice given by a dietitian compared with another health professional, or the use of self-help resources, in reducing blood cholesterol in adults. SEARCH STRATEGY We searched The Cochrane Library (to Issue 2 1999), MEDLINE (1966 to January 1999), EMBASE (1980 to December 1998), Cinahl (1982 to December 1998), Human Nutrition (1991 to 1998), Science Citation Index, Social Sciences Citation Index, hand searched conference proceedings on nutrition and heart disease, and contacted experts in the field. SELECTION CRITERIA Randomised trials of dietary advice given by a dietitian compared with another health professional or self-help resources. The main outcome was difference in blood cholesterol between dietitian groups compared with other intervention groups. DATA COLLECTION AND ANALYSIS Two reviewers independently extracted data and assessed study quality. MAIN RESULTS Eleven studies with 12 comparisons were included, involving 704 people receiving advice from dietitians, 486 from other health professionals and 551 people using self-help leaflets. Four studies compared dietitian with doctor, seven with self-help resources, and one compared dietitian with nurse. Participants receiving advice from dietitians experienced a greater reduction in blood cholesterol than those receiving advice only from doctors (-0.25 mmol/L (95% CI -0.37, -0.12 mmol/L)). There was no statistically significant difference in change in blood cholesterol between dietitians and self-help resources (-0.10 mmol/L (95% CI -0.22, 0.03 mmol/L)). No statistically significant differences were detected for secondary outcome measures between any of the comparisons with the exception of dietitian versus nurse for HDLc, where the dietitian groups showed a greater reduction (-0.06 mmol/L (95% CI -0.11, -0.01)). No significant heterogeneity between the studies was detected. REVIEWER'S CONCLUSIONS Dietitians were better than doctors at lowering blood cholesterol in the short to medium term, but there was no evidence that they were better than self-help resources. The results should be interpreted with caution as the studies were not of good quality and the analysis was based on a limited number of trials. More evidence is required to assess whether change can be maintained in the longer term. There was no evidence that dietitians provided better outcomes than nurses.

Abstract
OBJECTIVES The main purpose of this study is to compare sexually transmitted disease (STD) prevalence in cohorts of women with and without access to female condoms. METHODS Six matched pairs of communities were identified from Kenya tea, coffee and flower plantations. One community within each pair was randomly selected to receive the female condom intervention. Approximately 160 eligible women were enrolled at each site. Female condom communities underwent an education program on use of female and male condoms and STDs, comprising group meetings, puppetry and other folk media, and training of clinic service providers and community outreach workers. Control communities received similar information on use of male condoms (freely available at all sites). At baseline, participants were tested for cervical gonorrhea and chlamydia and vaginal trichomoniasis, to be repeated at 6 and 12 months. The study has 80% power to detect a 10% prevalence difference, assuming an aggregate STD prevalence of 20% with 25% loss to follow-up and intracluster correlation of 0.03. RESULTS Among 1929 women at baseline, the mean age was 33.1 years; 78% had never used a male condom. The prevalences of gonorrhea, chlamydia and trichomoniasis were 2.6%, 3. 2% and 20.4%, respectively (23.9% overall). The intracluster correlation based on these data was near zero. CONCLUSIONS Comparable pairs of study sites have been selected. STD prevalence is sufficiently high, and the variation between sites is acceptably low. The study is feasible as designed.

Abstract
OBJECTIVES To compare the effects of a worksite intervention by the occupational physician offering simple advice of smoking cessation with a more active strategy of advice including a "quit date" and extra support. POPULATION Employees of an electrical and gas company seen at the annual visit by their occupational physicians. CRITERIA END POINTS: Smoking point prevalence defined as the percentage of smokers who were non-smokers at one year. Secondary criteria were the percentage of smokers who stopped smoking for more than six months and the difference in prevalence of smoking in both groups. METHODS Randomised controlled trial. The unit of randomisation was the work site physician and a random sample of the employees of whom he or she was in charge. The length of the follow up was one year. Each of 30 work site physicians included in the study 100 to 150 employees. RESULTS Among 504 subjects classified as smokers at baseline receiving simple advice (group A) and 591 the more active programme (group B), 68 (13.5%) in group A and 109 (18. 4%) were non-smokers one year later (p=0.03; p=0.01 taking the occupational physician as the statistical unit and using a non-parametric test). Twenty three subjects (4.6%) in group A and 36 (6.1%) in group B (p=0.26) declared abstinence of six months or more. Among non-smokers at baseline, 3.4% in both groups were smokers after one year follow up. The prevalence of smokers did not differ significantly at baseline (32.9% and 32.4%, p=0.75). After the intervention the prevalence of smoking was 30.8% in group A and 28. 7% in group B (p=0.19). An increase of the mean symptoms score for depression in those who quit was observed during this period. CONCLUSIONS A simple cessation intervention strategy during a mandatory annual examination, targeting a population of smokers independently of their motivation to stop smoking or their health status, showed a 36% relative increase of the proportion of smokers who quit smoking as compared with what can be achieved through simple advice.

Abstract
BACKGROUND The workplace provides a useful setting for early identification and intervention with individuals who have unhealthy lifestyles. The objective was to evaluate the effects of a workplace-based lifestyle intervention (Workscreen) to reduce excessive drinking. METHOD There were eight Australia Post networks randomly allocated to experimental and control conditions, comprising 67 worksites and 1206 employees. The experimental condition involved a broad spectrum lifestyle campaign, incorporating support from management, employee awareness of health, and brief interventions for high-risk behaviors, including excessive alcohol use. Focus groups identified relevant cultural factors. Changes in workplace culture and employee behavior were assessed 10 months after baseline. Males and females were analyzed separately. RESULTS Over half of APOST employees participated at each screening point. In the experimental condition 61% of employees overall and 58% of those identified as excessive drinkers in Phase 1 responded to the lifestyle campaign by attending health assessments. Analyses focusing on the organization as a whole did not reveal significant reductions in excessive alcohol consumption among men or women. However, a significant reduction in number of drinks was observed in the experimental condition among women for whom completion of baseline and follow-up could be confirmed (P < 0.001). CONCLUSIONS The present study indicates that a workplace-based lifestyle campaign can assist self-selected employees in reducing their alcohol consumption. There was a moderately high level of participation among those identified as drinking excessively, which supports our approach of embedding a low-intensity alcohol program within the context of a broader health promotion campaign.

Abstract
BACKGROUND Primary prevention programmes in many countries attempt to reduce mortality and morbidity due to coronary heart disease through risk factor modification. It is widely believed that multiple risk factor intervention using counselling and educational methods is efficacious and cost-effective and should be expanded. Recent trials examining risk factor changes have cast considerable doubt on the effectiveness of these multiple risk factor interventions. OBJECTIVES To assess the effects of multiple risk factor intervention for reducing cardiovascular risk factors, total mortality, and mortality from coronary heart disease among adults without clinical evidence of established cardiovascular disease. SEARCH STRATEGY We searched Medline using a standard randomised trial filter. Date of the most recent search was April 1995. SELECTION CRITERIA Intervention studies using counseling or education to modify more than one cardiovascular risk factor in adults from general populations, occupational groups, or high risk groups. Trials of less than 6 months duration were excluded. DATA COLLECTION AND ANALYSIS Both reviewers, independently extracted data. Investigators were contacted to obtain missing information. MAIN RESULTS A total of 18 trials were found of which 10 reported clinical event data. Net changes in systolic and diastolic blood pressure, smoking prevalence, and blood cholesterol were -3.9mmHg (95% CI -4.2,-3.6 mmHg), -2.9 mmHg (95% CI -3.1,-2.7 mmHg), -4.2% (95% CI -4.8, -3.6%), and -0.08mMol/l (95% CI -0.1.-0.06 mMol/l) respectively. In the ten trials with clinical event end-points, the pooled odds ratios for total and coronary heart disease mortality were 0.97 (95% confidence intervals (CI) 0.92-1.02) and 0.97 (95% CI 0.88-1.04) respectively. Statistical heterogeneity between the studies with respect to mortality and risk factor changes was due to trials focusing on hypertensive participants and those using considerable amounts of drug treatment. Only these trials demonstrating significant reductions in mortality. REVIEWER'S CONCLUSIONS The pooled effects suggest multiple risk factor intervention has no effect on mortality. However, a small, but potentially important, benefit of treatment (about a 10% reduction in CHD mortality) may have been missed. Risk factor changes were relatively modest, were related to the amount of pharmacological treatment used, and in some cases may have been over-estimated because of regression to the mean effects, lack of intention to treat analyses, habituation to blood pressure measurement, and use of self-reports of smoking. Interventions using personal or family counseling and education with or without pharmacological treatments appear to be more effective at achieving risk factor reduction and consequent reductions in mortality in high risk hypertensive populations. The evidence suggests that such interventions have limited utility in the general population.

Abstract
One in four U.S. adults smokes. Downstream cognitive-behavioral interventions coupled with effective pharmacotherapy can produce 40% quit rates, particularly for those least addicted, most highly motivated, and without psychiatric comorbidity. Effective midstream school-based prevention activities delay youth use. Worksite programs and physician "quit smoking" advice can be cost-effective, although these are not sufficiently widespread. Community strategies show promise of preventing youth use and helping addicted users quit. Despite failed federal tobacco control legislation, great strides have been made upstream, including proposed regulation of nicotine as a drug, the state master settlement agreement with the tobacco industry, and excise tax increases funding statewide tobacco control programs. Wider dissemination of effective programs and better coordination with upstream policies hold great potential to significantly reduce future use rates and related disease.

Abstract
STUDY OBJECTIVE The aim of this study was to evaluate the impact of a smoke free programme implemented at the University of Geneva, Switzerland, in 1996. This programme included a prohibition to smoke in university buildings everywhere except in limited areas, and a smoking cessation counselling service. METHODS Surveys were conducted before and four months after the programme was implemented, in representative samples of programme participants (n = 833) and university members not exposed to the programme (n = 1023). RESULTS In retrospective assessments, participants reported being less bothered by environmental tobacco smoke after programme implementation, but no between group difference was detected in prospective assessments. Relationships between smokers and non-smokers improved moderately in the intervention group and remained unchanged in the comparison group (between group p = 0.001). Proportions of smokers who attempted to quit smoking in the past four months increased from 2.0% to 3.8% in the intervention group and remained unchanged at 3.5% in the comparison group (between group difference: p = 0.048). No impact on smoking prevalence (25%) was detected. The programme was appreciated by university members, although some of its modalities were criticised. CONCLUSION A regulation prohibiting smoking everywhere but in limited areas of university buildings was acceptable and reduced the perception of bother by environmental tobacco smoke. It did not, however, influence smoking habits or attitudes toward smoking.

Abstract
Worksites are a key channel for delivery of interventions designed to reduce chronic disease among adult populations. Although some evaluations of worksite physical-activity interventions have been conducted, to date very few randomized trials of worksite health promotion have included the goal of increasing physical-activity levels as part of a comprehensive multiple risk factor approach to worksite health promotion. This article presents the results regarding behavior change found among the cohort of 2055 individuals who completed three health-behavior assessments as part of their worksites' participation in The Working Healthy Project (WHP), a multiple risk factor intervention implemented in 26 manufacturing worksites. In this study, a randomized matched-pair design was used. Fifty-one percent (n = 2,761) of the employees who completed the baseline assessment also completed the interim survey. Eighty-three percent of those who completed the interim assessment also completed the final survey. The WHP intervention targeted smoking, nutrition, and physical activity. At baseline, 38% of the sample reported engaging in regular exercise, and subjects reported consuming an average of 2.7 servings of fruits and vegetables per day, 7.9 grams of fiber per 1000 kilocalories, and 35.4% calories from fat per day; 28% of the sample were smokers. By the time of both the interim (intervention midpoint) and final (end of intervention) assessments, participants in the intervention condition had significantly increased their exercise behavior, compared with the control condition. There was also increased consumption of fruits and vegetables and fiber in the intervention condition by the time of the final assessment, compared with the control condition. No differences by condition were found with regard to percentage of calories from fat consumed or smoking cessation. These results suggest that among a cohort of participants in a worksite health promotion study, there were significant health behavior changes across two risk factors over time. These data suggest that further investigation of multiple risk factor worksite health promotion is warranted, particularly with a focus on ways to increase participation in these programs and to diffuse intervention effects throughout the entire workforce.

Abstract
BACKGROUND The most recent major U.S. trials that evaluated community-level programs to influence risk factors and health behaviors identified secular trends in the risk factors and health behaviors among the factors that might have limited community-level effects. The research reported in this paper uses data from one of the trials to examine the secular trend explanation directly. METHODS Data from the 22-community Community Intervention Trial for Smoking Cessation (COMMIT) were analyzed to test a hypothesis based on secular trend reasoning: program effects for smoking prevalence were larger for treatment communities matched to control communities with small declines in smoking than in treatment communities matched to control communities with larger declines in smoking. RESULTS Consistent with the secular trend explanation, program effects were larger when control communities had relatively small declines in smoking prevalence. CONCLUSIONS The findings suggest that secular trends masked community-level program effects in COMMIT.

Abstract
The most common methods for the economic evaluation of a fitness program at a worksite are cost-effectiveness, cost-benefit, and cost-utility analyses. In this study, we applied a basic microeconomic theory, "neoclassical firm's problems," as the new approach for it. The optimal number of physical-exercise classes that constitute the core of the fitness program are determined using the cubic health production function. The optimal number is defined as the number that maximizes the profit of the program. The optimal number corresponding to any willingness-to-pay amount of the participants for the effectiveness of the program is presented using a graph. For example, if the willingness-to-pay is $800, the optimal number of classes is 23. Our method can be applied to the evaluation of any health care program if the health production function can be estimated.

Abstract
The Pathways to Change system (PTC) is an expert system intervention for smoking cessation. Assessments are performed either by mail or by a telephone interview and each smoker receives a three- to four-page report that provides individualized recommendations matched to the individual's needs and readiness-to-change. The Transtheoretical Model of Change provides the theoretical basis for the expert system. Four different studies have demonstrated the efficacy of this intervention in a general population, with cessation rates of 22 to 26%. Furthermore, the difference between the groups was larger at each follow-up assessment point, indicating that the effects of the treatment increased long after the end of treatment. The studies involved two proactively recruited samples, demonstrating that a large proportion (85.3% and 82.5%) of the population of smokers could be successfully recruited into a smoking cessation program. Expert system interventions have the potential to have an extremely high impact on a total population of smokers.

Abstract
This article assesses the validity and reliability of the approach used to measure community mobilization in the Seattle Minority Youth Health Project (MY Health), a neighborhood-based program to prevent drug use, violence, teen pregnancy, and sexually transmitted diseases (STDs). Two constructs were measured: neighborhood cooperation in solving problems, and sense of pride and identification with the neighborhood. The convergent validity of the measurement approach was assessed by comparing several independent measures of community mobilization generated from surveys of key neighborhood leaders, youth, and parents. For the neighborhood cooperation construct, correlations were uniformly positive across measures from different surveys and statistically significant about a quarter of the time. The correlations for the neighborhood pride construct were weaker and generally not statistically significant. Interrater reliability was low for all of the surveys, possibly reflecting varying ideas about what community mobilization meant among survey respondents.

Abstract
OBJECTIVES This study assessed the effects of a 2-year integrated health promotion-health protection work-site intervention on changes in dietary habits and cigarette smoking. METHODS A randomized, controlled intervention study used the work site as the unit of intervention and analysis; it included 24 predominantly manufacturing work sites in Massachusetts (250-2500 workers per site). Behaviors were assessed in self-administered surveys (n = 2386; completion rates = 61% at baseline, 62% at final). Three key intervention elements targeted health behavior change: (1) joint worker-management participation in program planning and implementation, (2) consultation with management on work-site environmental changes, and (3) health education programs. RESULTS Significant differences between intervention and control work sites included reductions in the percentage of calories consumed as fat (2.3% vs 1.5% kcal) and increases in servings of fruit and vegetables (10% vs 4% increase). The intervention had a significant effect on fiber consumption among skilled and unskilled laborers. No significant effects were observed for smoking cessation. CONCLUSIONS Although the size of the effects of this intervention are modest, on a populationwide basis effects of this size could have a large impact on cancer-related and coronary heart disease end points.

Abstract
This article reports on one of the few experimental studies in Europe to examine work site smoking cessation. The study examined whether a comprehensive intervention (self-help manuals, group courses, a mass media campaign, smoking policies, and a second-year program) is more effective than a minimal intervention (self-help manuals only). Eight work sites participated in the study. The effect of treatment on smoking cessation depended on nicotine dependency levels: Heavy smokers had more success with the comprehensive smoking cessation intervention than with the minimal intervention (with respect to both 14-month quit rate and 6-month prolonged abstinence). For heavy smokers, exposure to mass media exhibitions or to group courses had a beneficial effect on prolonged abstinence. Comprehensive programs may be most appropriate in Dutch work sites with large proportions of heavily addicted smokers.

Abstract
BACKGROUND Gender differences in smoking and smoking cessation among participants in the Working Well Trial are characterized. METHODS A prospective randomized matched-pair evaluation was conducted among 90 predominantly blue-collar worksites. Cross-sectional surveys of employees' tobacco use behaviors were conducted at baseline and after a 2.5-year smoking cessation intervention. Respondents included 5,523 females and 12,313 males at baseline and 4,663 females and 10,919 males at follow-up. The main outcome measures included self-reported continuous smoking abstinence rates for 7 days and for 6 months. RESULTS Smoking prevalence was significantly higher for women than for men at baseline, but not at follow-up. Variables believed to influence smoking cessation were compared at baseline. Significant gender differences were found for number of cigarettes smoked/day, number of previous quit attempts, job strain, stage of change, and behavioral processes of change. At follow-up, no gender differences in quit rates were observed; however, women in the intervention condition were more likely to quit than women in the control condition, whereas no differences were seen among men by treatment condition. CONCLUSIONS Gender is not a strong predictor of smoking cessation in this population; however, women were more likely to quit with an intervention than without one.

Abstract
This paper examines the results of population-level interventions conducted in three settings: entire communities, worksites, and schools. Four major conclusions are discussed: (a) Directions for the next generation of community-based interventions include targeting multiple levels of influence; addressing social inequalities in disease risk; involving communities in program planning and implementation; incorporating approaches for "tailoring" interventions; and utilizing rigorous process evaluation. (b) In addition to randomized controlled trials, it is time to use the full range of research phases available, from hypothesis generation and methods development to dissemination research. (c) The public health research agenda may have contributed to observed secular trends by placing behavioral risk factors on the social and media agendas. (d) The magnitude of the results of community intervention trials must be judged according to their potential public health or population-level effects. Small changes at the individual level may result in large benefits at the population level.

Abstract
OBJECTIVE This study examined whether providing a school-based teacher wellness program enhances the impact of a health curriculum on student outcomes and improves cognitive, behavioral, and physiological outcomes among participating teachers. METHODS Thirty-two elementary schools were randomly assigned to experimental or comparison conditions. Comparison group schools received the Gimme-5 program, a curriculum designed to increase fourth and fifty graders' consumption of fruits and vegetables. Experimental schools received Gimme-5 and the teacher wellness program, which included 54 workshops over 2 years, along with several schoolwide health activities. Physiological, behavioral, and cognitive outcomes were assessed in teachers and students. RESULTS There was no evidence that the intervention favorably modified any student or teacher end points; nor did intervention teachers deliver the Gimme-5 program with greater fidelity than comparison teachers. CONCLUSION Confidence in the null results is bolstered by the randomized design, baseline sample equivalence, appropriate mixed-model analyses, and lack of selective or differential attrition. Insufficient participation in the wellness program appears a likely explanation for the lack of teacher and student effects. Factors specific to the school setting and intervention may have diminished participation and, thus, intervention effects.

Abstract
Following a brief review of the etiology and prevalence of tobacco use and data on the effectiveness of prevention and cessation interventions, recommendations for a research agenda are outlined. It is suggested that research on youth tobacco initiation and cessation be given highest priority because of rising prevalence rates, fundamental social importance, and the widespread support for such efforts. Policy and community approaches to deterring youth tobacco use deserve particular attention. Adult intervention research should focus on health care settings and include factors that both help and hinder adoption and routine implementation of tobacco interventions by clinicians. Developing and evaluating practical ways of using nicotine replacement therapies or other pharmacological therapies in primary care are also of importance. Media interventions that segment the smoking population by age, ethnicity, and developmental milestones should be encouraged. Three approaches could profit from working conferences of investigators and other interested parties to review the data and suggest research directions: worksite interventions, interventions with ethnic populations, and matching or tailoring interventions to specified characteristics of smokers. The importance of devoting considerable resources to investigator-initiated contrasted with sponsor-directed research is discussed.

Abstract
PURPOSE In this study, the type and size of participating and nonparticipating worksites in a health promotion research trial were examined. DESIGN In-person and telephone contacts were made with representatives from a random sample of eligible worksites recruited to participate in a research trial to increase fruit and vegetable consumption. SETTING Worksites that had 250 to 2000 employees and a worksite cafeteria were recruited. SUBJECTS Eighty-one worksites were contacted. MEASURES A census of eligible worksites (N = 109) formed the recruitment base, and a random selection of worksites (N = 81) was personally contacted and asked to participate in the research. Information on size, type of worksite, and a worksite representative was obtained from a privately compiled list covering the greater Puget Sound area. Eligibility for the project included the presence of an onsite cafeteria at the worksite as assessed by a brief telephone call. RESULTS Thirty-six of the contacted worksites (44.5%) agreed to participate. There were no significant differences in participation by type or size of worksite. DISCUSSION Worksites can be recruited to participate in research trials. No particular type or size of worksite is more likely to participate. Instituting pre-randomization participation conditions may reduce post-randomization dropout by ascertaining compliance with research requirements before randomization.

Abstract
The purpose of this study was to evaluate the effects of a revised worksite health promotion program that featured an employee steering committee/menu approach to intervention. The "Take Heart II" program was evaluated using a quasi-experimental matched-pair design with worksite as the unit of analysis. Experimental and control worksites did not differ on baseline organizational or employee demographic variables or on baseline levels of dependent variables. Outcome and process results revealed consistent, but modest effects favoring intervention worksites on most measures. Cross-sectional analyses generally failed to produce statistically significant intervention effects, but cohort analyses revealed significant beneficial effects of the Take Heart II intervention on eating patterns, behavior change attempts, and perceived social support. Neither analysis detected a beneficial effect of intervention on cholesterol levels.

Abstract
OBJECTIVES Two composite outcome measures were used to assess the efficacy of work-site risk factor interventions: the Framingham multiple logistic function and a standardized composite equation that was an unweighted combination of risk factors. METHODS Twenty-eight work sites in Sydney, Australia, were randomly assigned to health risk assessment, risk factor education, behavioral counseling, or behavioral counseling plus incentives. RESULTS Over 12 months, scores on the multiple logistic function increased for the behavioral counseling plus incentives condition relative to the other conditions. Standardized scores decreased for behavioral counseling relative to the incentive condition and the average of all other conditions. CONCLUSIONS Behavioral counseling produces larger changes in the life-style behaviors contributing to coronary heart disease risk than other commonly used interventions.

Abstract
PURPOSE The purpose of this article is to critically review evaluation studies of the health-related effects (i.e., health risk modification and reduction in worker absenteeism) of multicomponent worksite health promotion programs. SEARCH METHOD A comprehensive literature search conducted under the auspices of the Centers for Disease Control and Prevention identified 36 articles that examined health-related outcomes of multi-component programs. The authors identified 11 additional articles through manual searches of recent journal issues and through personal contacts with worksite health promotion researchers. Forty-seven studies describing the results of 35 worksite health promotion programs were reviewed. IMPORTANT FINDINGS The worksite health promotion programs reviewed for this article varied tremendously in the comprehensiveness, intensity, and duration of the intervention activities. All of the programs provided health education to employees. In a majority of the programs, opportunities to learn and practice new skills were also offered. A smaller number of programs incorporated modifications in organizational policy or the physical work environment. Results from well-conducted randomized trials suggest that providing opportunities for individual risk reduction counseling for high risk employees within the context of comprehensive programming may be the critical component of an effective worksite health promotion program. Just offering low intensity, short duration programs aimed at increasing awareness of health issues for the entire employee population may not be sufficient to achieve desired outcomes. MAJOR CONCLUSIONS The results of the studies reviewed provide both cautious optimism about the effectiveness of these worksite programs and some general guidance as to the critical components and characteristics of successful programs. Overall, the evidence suggests that a rating of indicative/acceptable may best characterize this literature.

Abstract
Clinical interventions for the addictions typically generate the highest abstinence rates but the lowest participation rates. Public health interventions reach the largest percentage of populations but have the lowest efficacy. Applying a stage paradigm to smoking cessation can integrate the clinical and public health approach and generate unprecedented impacts. Theoretical, empirical, and practical examples are provided for enhancing five issues in intervention: recruitment, retention, progress, process and outcomes.

Abstract
OBJECTIVES This paper presents the behavioral results of the Working Well Trial, the largest US work site cancer prevention and control trial to date. METHODS The Working Well Trial used a randomized, matched-pair evaluation design, with the work site as the unit of assignment and analysis. The study was conducted in 111 work sites (n = 28,000 workers). The effects of the intervention were evaluated by comparing changes in intervention and control work sites, as measured in cross-sectional surveys at baseline and follow-up. The 2-year intervention targeted both individuals and the work-site environment. RESULTS There occurred a net reduction in the percentage of energy obtained from fat consumption of 0.37 percentage points (P = .033), a net increase in fiber densities of 0.13 g/1000 kcal (P = .056), and an average increase in fruit and vegetable intake of 0.18 servings per day (P = .0001). Changes in tobacco use were in the desired direction but were not significant. CONCLUSIONS Significant but small differences were observed for nutrition. Positive trends, but no significant results, were observed in trial-wide smoking outcomes. The observed net differences were small owing to the substantial secular changes in target behaviors.

Abstract
PURPOSE This article provides the foundation for a series of literature reviews that critically examine the effectiveness of worksite health promotion programs. This issue reviews the exercise, health risk appraisal, nutrition and cholesterol, and weight control literatures; a future issue will review the alcohol, HIV/AIDS, multicomponent program, seat belt, smoking, and stress management literatures. METHODS The literature search used a four-step process that included a computerized database search, a reference search, a manual search of relevant health promotion journals, and the writing of the review by a recognized expert in the area being searched. The databases were searched from 1968 through 1994 and included Medline, Aidsline, Psychological Abstracts, Combined Health Information Database, Employee Benefits Infosource, National Prevention Evaluation Research Collection, National Resource Center on Worksite Health Promotion, National Technical Information Service, and the Substance Abuse Information database. A total of 288 articles were identified by the search, not including the 37 articles in the hypertension literature. Authors of each review were requested to incorporate additional studies not identified by the search, provide a research rating for each individual article, and a rating for the overall literature for their respective area. The authors reviewed 316 studies. FINDINGS The overall ratings for the reviews reported in this issue were suggestive for exercise, weak for health risk appraisals, suggestive/indicative for both nutrition and cholesterol, and indicative for weight control. The ratings for the other reviews will be reported in the subsequent issue. CONCLUSIONS Research reported in these reviews suggests the effectiveness of worksite health promotion programs, however, additional research is required to provide conclusive evidence of their impact.

Abstract
PURPOSE To address three specific questions in a sample of craftspersons and laborers: (1) Do craftspersons and laborers exposed to workplace hazards have higher behavioral risks, such as smoking and high-fat diets, than those with few job risks? (2) Compared to workers with few job risks, do workers exposed to risks on the job have higher intentions to reduce their behavioral risks? (3) Does concern about the level of exposure to risks on the job increase workers' intentions to reduce behavioral risks? DESIGN A cross-sectional self-administered survey was conducted in participating worksites. SETTING Twenty-two predominantly manufacturing worksites in Massachusetts. SUBJECTS Craftspersons and laborers responding to the survey and employed in these 22 worksites (completion rate = 61%, N = 1841). MEASURES By using standardized items, this survey measured self-reported exposure to workplace hazards, concern about job exposures, smoking status, fat and fiber intake, readiness to quit smoking, plans to reduce fat intake, plans to eat more fruits and vegetables, and sociodemographic variables. RESULTS Workers reporting exposure to chemical hazards on the job were significantly more likely to be smokers than were unexposed workers, even when results were controlled for gender. Compared with unexposed workers, smokers exposed to chemical hazards were significantly more likely to be thinking of quitting or taking action to quit, when results were controlled for gender, race, and education. Among workers exposed to occupational chemical hazards, concern about this exposure was significantly associated with intentions to decrease fat intake and increase fruit and vegetable intake, and, among men, intentions to quit smoking. CONCLUSIONS Efforts aimed at integrating health promotion and health protection are needed to address simultaneously the job risks and personal risks these workers face.

Abstract
According to prior reports, blue-collar workers are less likely to participate in worksite health promotion programs than are white-collar workers. This study examined worker participation in the WellWorks worksite cancer prevention intervention, which integrated health promotion and health protection. Analyses were conducted to assess relationships among participation in health promotion and health protection programs, and workers' perceptions of management changes to reduce potential occupational exposures. Results indicate that blue-collar workers were less likely to report participating in health promotion activities than white-collar workers. A significant association was observed between participation in nutrition- and exposure-related activities, suggesting that participation in programs to reduce exposures to occupational hazards might contribute to blue-collar workers' participation in health promotion activities. Furthermore, when workers were aware of changes their employer had made to reduce exposures to occupational hazards, they were more likely to participate in both smoking control and nutrition activities, even when controlling for job category. These findings have clear implications for future worksite cancer prevention efforts.

Abstract
Our research team is involved in ongoing research in both worksites and medical office settings. These settings offer great potential for reaching individuals who would not otherwise participate in health promotion, but they also place considerable constraints on assessment time and efforts, especially if one's goal is to attract a high and representative proportion of employees or patients. This paper reports on our experience with measures of dietary behavior in these two settings. We found it problematic to collect detailed assessments such as 4-day food records or comprehensive food frequency/history checklists in worksites or medical office settings using population-based samples. Instead, we recommend and provide data on the utility of a dietary-fat screening instrument, and on the Food Habits Questionnaire (FHQ-Kristal, Shattuck, & Henry, 1990), a brief measure of dietary behaviors associated with high-fat eating patterns. The FHQ, in particular, was found to correlate well with other more costly and time-consuming methods of assessment, to be reliable and responsive to intervention effects, and to provide behavioral targets for intervention. The strengths and limitations of these measures for tailoring intervention and assessing outcomes are discussed.
