Inferring strategies for disseminating physical activity policies, programs, and practices from the successes of tobacco control.

Efforts at reducing tobacco use in the United States and Canada over the last half century have been amazingly successful. This article examines those efforts in order to identify policies, programs, and practices found useful in tobacco control that might be usefully disseminated to world populations to improve rates of physical activity. Tobacco-control activities began with efforts to influence the individual smoker through public education and counter-advertising. Increasing awareness of the addictive properties of tobacco, industry efforts to manipulate those properties, and to target youth with aggressive advertising, fueled public outrage that supported additional policy changes to include community interventions, legal actions, and restraints against the tobacco industry. The article first examines ways to view the process of transferring knowledge from one enterprise (reducing tobacco consumption) to another (increasing physical activity). Several theories of knowledge generalization and dissemination are explored: transfer, knowledge utilization, application, diffusion, and implementation. The second section identifies the dissemination of tobacco control by means of brief health behavior-change interventions for smoking cessation that have been successfully integrated into primary clinical care. The question of whether similar strategies can be successfully disseminated to increase physical activity is examined in detail. The article then moves on to look at the success of arguably the most successful program in the world at achieving a reduction in tobacco control-the State of California. Finally, we compare and contrast some of the lessons as they have played out in another national context-Canada. In the concluding section, some lessons are identified that we believe may be successfully utilized in societal attempts to increase physical activity in world populations.

Indicators of activity-friendly communities: an evidence-based consensus process.

BACKGROUND: Regular physical activity, even at modest intensities, is associated with many health benefits. Most Americans, however, do not engage in the recommended levels. As practitioners seek ways to increase population rates of physical activity, interventions and advocacy efforts are being targeted to the community level. Yet, advocates, community leaders, and researchers lack the tools needed to assess local barriers to and opportunities for more active, healthy lifestyles. Investigators used a systematic review process to identify key indicators of activity-friendly communities that can assess and improve opportunities for regular physical activity. METHODS: Investigators conducted a comprehensive literature review of both peer-reviewed literature and fugitive information (e.g., reports and websites) to generate an initial list of indicators for review (n=230). The review included a three-tiered, modified Delphi consensus-development process that incorporated input of international, national, state, and local researchers and practitioners from academic institutions, federal and state government agencies, nonprofit organizations, and funding agencies in public health, transportation, urban planning, parks and recreation, and public policy. RESULTS: Ten promising indicators of activity-friendly communities were identified: land use environment, access to exercise facilities, transportation environment, aesthetics, travel patterns, social environment, land use economics, transportation economics, institutional and organizational policies, and promotion. CONCLUSIONS: Collaborative, multidisciplinary approaches are underway to test, refine, and expand this initial list of indicators and to develop measures that communities, community leaders, and policymakers can use to design more activity-friendly community environments.

Physician and enrollee knowledge of Medicaid coverage for tobacco dependence treatments.

BACKGROUND: The 2000 Public Health Service Clinical Practice Guideline, Treating Tobacco Use and Dependence, recommends health insurance coverage for tobacco-dependence treatments proven effective in helping smokers to quit. Two states with comprehensive coverage for tobacco-dependence treatments in their Medicaid programs were selected to document awareness of coverage for tobacco-dependence treatments among primary care physicians who treat Medicaid enrollees and Medicaid-enrolled smokers. METHODS: In 2000, surveys were conducted among Medicaid smokers (n =400) and physicians (n =160) to document knowledge of covered tobacco-dependence treatments under state Medicaid programs in two states with comprehensive coverage. RESULTS: Only 36% of Medicaid-enrolled smokers and 60% of Medicaid physicians knew that their state Medicaid program offered any coverage for tobacco-dependence treatments. Physicians were more than twice as likely to know that pharmacotherapies were covered compared to counseling. CONCLUSIONS: Greater effort is needed to make Medicaid smokers and physicians aware that effective pharmacotherapies and counseling services are available to assist in treating tobacco dependence. Additionally, future research should explore the methods that are most effective in informing patients and providers regarding covered benefits.

Physician screening for multiple behavioral health risk factors.

BACKGROUND: Screening rates in primary care for single behavioral health risk factors are widely documented. However, such risk factors cluster in individuals and populations. This article examines the number and types of behavioral risk factors that U.S. adults reported, and reported having been screened for in their last routine medical checkup. METHODS: The sample consisted of 16,818 adults from the 1998 National Health Interview Survey who reported having a routine checkup in the past year. Respondents completed questions regarding four behavioral risk factors (physical inactivity, overweight, cigarette smoking, risky drinking), and provider screening for behaviors related to these risk factors. RESULTS: Half of the sample (52.0%) reported having two or more of the four risk factors, and more than half (59.4%) were screened for two or more risk behaviors during their last routine checkup, although 28.6% reported being screened for none of them. Respondents reporting at least one risk factor were screened for an average of 57.7% of their own risk factors. Women, adults with lower levels of income and education, and those aged 65 and older, reported being screened for fewer of their risk factors. CONCLUSIONS: While guidelines for risk factor screening and intervention typically focus on single behavioral risk factors, most primary care patients present with, and are screened for, more than one. Behavioral risk factor screening tools and interventions must be expanded to cover multiple risks. Additionally, efforts are needed to reduce the substantial missed opportunities for screening, and to eliminate demographic disparities in screening practices and accuracy.

Prevention and health promotion: decades of progress, new challenges, and an emerging agenda.

Daily habits (e.g., smoking, diet, and exercise) and their immediate consequences (e.g., obesity) confer risk for most of the major health problems in industrialized nations. Hence, determinants of these behaviors and their modifications have been central topics in health psychology. Considerable scientific and applied progress has been made, but the field faces important challenges and opportunities in the future. These challenges and opportunities include changes in demographics and patterns of health, the need for a more comprehensive model of the domain of health behavior and prevention, the need to integrate behavioral and psychosocial risk and resilience, the incorporation of new technologies, and addressing a variety of professional and economic barriers to the implementation of prevention in health care.

A primer on current evidence-based review systems and their implications for behavioral medicine.

BACKGROUND: Multiple review systems have been established within medicine and psychology to evaluate and disseminate research findings to clinical practice. PURPOSE: Within this article, five evidence-based review systems are reviewed to inform the development or the use of an evidence review system for the behavioral medicine field. METHODS: Each review system is described on several dimensions: history of the review system, the review process, and details about translation/sustainability efforts. RESULTS: Various factors from each system have been identified that would benefit a behavioral medicine evidence review system, such as a discussion of clinical features that influence the generalizability of review findings (i.e., the American Psychiatric Association) and the use of pre-review protocols (i.e., the Cochrane Collaboration). CONCLUSIONS: Although each review system has limitations, it is important for behavioral medicine to join one system because (a) systematic reviews are the only feasible means to evaluate and judge the usefulness of our interventions, and (b) reviews can inform policy, and, with effort, influence patient well-being. This group of behavioral medicine experts recommends that the Cochrane Collaboration review behavioral medicine interventions.

Preventing 3 million premature deaths and helping 5 million smokers quit: a national action plan for tobacco cessation.

In August 2002, the Subcommittee on Cessation of the Interagency Committee on Smoking and Health (ICSH) was charged with developing recommendations to substantially increase rates of tobacco cessation in the United States. The subcommittee's report, A National Action Plan for Tobacco Cessation, outlines 10 recommendations for reducing premature morbidity and mortality by helping millions of Americans stop using tobacco. The plan includes both evidence-based, population-wide strategies designed to promote cessation (e.g., a national quitline network) and a Smokers' Health Fund to finance the programs (through a 2 US dollar per pack excise tax increase). The subcommittee report was presented to the ICSH (February 11, 2003), which unanimously endorsed sending it to Secretary Thompson for his consideration. In this article, we summarize the national action plan.

Promoting the uptake of evidence in clinical practice: a prescription for action.

In many respects, obstetrics, perinatology, and neonatology have been at the forefront in the dissemination and uptake of evidence-based medicine. The work of the Cochrane Collaboration began largely with the need to systematize the evidence on these subjects. Among other organizations, the National Perinatal Information Service and the Vermont Oxford Network represent exemplary efforts to promote the uptake of evidence. With this background and support, the reader should be equipped to use the tools and examples provided in this article to promote evidence-based practice in his or her own practice setting.

Counseling to promote a healthy diet in adults: a summary of the evidence for the U.S. Preventive Services Task Force.

OBJECTIVE: The purpose of this study was to examine the effectiveness of counseling to promote a healthy diet among patients in primary care settings. DESIGN AND DATA SOURCES: We conducted a MEDLINE search from 1966 to December 2001. STUDY SELECTION: We included randomized controlled trials of at least 3 months' duration with measures of dietary behavior that were conducted in patient populations similar to those found in primary care practices. We excluded studies that reported only biochemical or anthropomorphic endpoints, had dropout rates greater than 50%, or enrolled patients based on the presence of a chronic disease. DATA EXTRACTION: One author extracted relevant data from each included article into evidence tables. Using definitions developed by the research team, two authors independently rated each study in terms of its effect size, the intensity of its intervention, the patient risk level, and the use of well-proven counseling techniques. DATA SYNTHESIS: We identified 21 trials for use in this review. Dietary counseling produces modest changes in self-reported consumption of saturated fat, fruits and vegetables, and possibly dietary fiber. More-intensive interventions were more likely to produce important changes than brief interventions, but they may be more difficult to apply to typical primary care patients. Interventions using interactive health communications, including computer-generated telephone or mail messages, can also produce moderate dietary changes. CONCLUSIONS: Moderate- or high-intensity counseling interventions, including use of interactive health communication tools, can reduce consumption of saturated fat and increase intake of fruit and vegetable. Brief counseling of unselected patients by primary care providers appears to produce small changes in dietary behavior, but its effect on health outcomes is unclear.
