The Steps program, formerly known as Steps to a HealthierUS, was the first Centers for Disease Control and Prevention (CDC) program to support a community-based, integrated approach to chronic disease prevention. Steps interventions addressed both diseases and risk factors, focusing on the 3 leading causes of preventable deaths in the United States — tobacco use, poor nutrition, and physical inactivity — and the associated chronic conditions of asthma, diabetes, and obesity. When Steps shifted from interventions focused on individual health-risk behaviors to the implementation of policy, systems, and environmental changes, the program became an integral part of changing the way CDC addressed chronic disease prevention. In this article, we describe the shift in intervention strategies that occurred among Steps communities, the model that was developed as Steps evolved, common interventions implemented before and after the shift in approach, challenges experienced by Steps communities, and CDC programs that were modeled after Steps.
To address the 3 leading causes of preventable deaths in the United States — tobacco use, poor nutrition, and physical inactivity and the associated chronic conditions of asthma, diabetes, and obesity, the — Centers for Disease Control and Prevention (CDC) implemented the Steps program, formerly known as Steps to a HealthierUS, in 2003. At that time, tobacco use, the most avoidable actual cause of death, caused illness among 8.6 million people in the United States (1). Poor diet and lack of exercise, the second and third actual causes of preventable death, were leading contributors to an obesity epidemic (2). Asthma and type 2 diabetes rates had also reached epidemic proportions (3,4). Prevalence of disabling asthma among children (categorized by the National Health Interview Survey as asthma that limits children's ability to perform usual activities) had increased 232% during the past 4 decades (5) and diabetes rates had more than doubled (4). Researchers predicted that one-third of all people born in 2000 would develop type 2 diabetes during their lifetime (4). Obesity rates also doubled from 1980 through 2002 (6), and by 2002, more than 22% of adults were obese (defined as body mass index ≥30 kg/m2) (7). Comprehensive efforts to combat unhealthy behaviors that contributed to the rising rates of chronic disease were needed.
Steps comprised 2 cooperative agreements coordinated by CDC and funded by the Department of Health and Human Services (HHS) in fiscal years 2003 and 2004. Forty communities (Figure 1) and 1 national partner (YMCA of the USA) were selected for funding according to the following criteria: ability to demonstrate public health capacity and expertise to implement Steps initiatives; demonstrated need based on high rates of asthma, diabetes, and obesity compared with the national average; existence of disparate populations with inadequate access to quality care; and proposed program goals and objectives. In fiscal year 2003, HHS distributed $13.6 million to12 grantees representing 24 communities. In fiscal year 2004, HHS distributed an additional $35.8 million to increase support to existing communities and fund 10 additional grantees representing 16 communities. In fiscal year 2004, HHS also distributed $2 million to the YMCA of the USA to partner with Steps communities and increase the reach of Steps-funded efforts.
Whereas most programs at CDC addressed a specific disease, condition, or risk factor in a particular setting and among a certain population until program funding ended, Steps interventions encompassed multiple diseases and risk factors, served entire communities, and were designed to be sustainable beyond federal funding.
Steps interventions addressed all levels of the social ecological model (SEM) (8) — individual, interpersonal, organizational, community, and public policy — to prevent and control health outcomes related to asthma, diabetes, and obesity.
In Steps' earlier years (2003-2006), communities primarily implemented evidence-based interventions focused on changing health behavior at the individual level. Interventions were aimed at increasing awareness and educating participants about chronic disease prevention, such as diabetes self-management training, nutrition education, and smoking cessation classes. Steps communities came to the common realization that, because characteristics of a healthy community were interdependent, a comprehensive approach was required to maximize Steps' potential. These characteristics included the built environment (eg, sidewalks, bicycle paths, and walking trails that promote physical activity); accessibility and availability of population-based health programs (eg, interventions offered in community clinics); access to healthy foods in restaurants, cafeterias, convenience stores, and farmers' markets; and health behavior (eg, walking or bicycling to destinations, eating healthy foods). It became evident that a systems approach involving policy and environmental change strategies was needed, because interventions aimed at individuals could reach only a small percentage of the population at a time. Steps communities reported that these programs reached 100 people or fewer per intervention, whereas a typical systems or policy approach could reach hundreds to hundreds of thousands of people in the same period.
Steps communities mobilized key decision makers and community members to increase awareness about the need for altering the social and built environment to support healthy living. They strengthened their coalitions to include key business leaders, county and city planners, transportation professionals, and local elected officials to help foster changes to the local food and physical environments. Grassroots movements to pass local ordinances such as trans-fat bans (9-11), menu-labeling legislation (12,13), and smoke-free housing (14) emerged, and Steps communities became leaders in community-level change. By the end of 2006, Steps communities embraced a model for chronic disease prevention that focused on the implementation of sustainable, practice- or evidence-based policy, systems, and environmental (PSE) changes to prevent and control rising rates of asthma, diabetes, and obesity. By 2008, Steps' approach was recognized in a report by Trust for America's Health as a successful community-based public health intervention approach that could be cost-effective and estimated that the program could save $16 billion in US health care costs annually within 5 years (15). CDC developed the Steps Model (Figure 2) to highlight Steps' PSE change approach.
Performance measurement was the centerpiece of evaluating Steps communities as a whole. Together, Steps program staff and stakeholders developed a set of 18 performance measures (8 implementation measures and 10 outcome measures) and 44 indicators (for implementation and outcome measures) (Appendix).
Steps communities reported their progress annually during 2003 through 2010, using the performance measures reporting system. Process measures summarized the communities' progress in using evidence-based strategies, leveraging partner resources to support Steps initiatives, and integrating program components.
The communities tracked implementation measures and related indicators using community-specific data collection methods and tools. Implementation indicators included numbers of interventions that addressed multiple risk factors in different sectors and at multiple levels of the SEM.
Outcome measures and related indicators included physical activity and nutrition behaviors, access to and quality of clinical services, and management of chronic diseases and conditions (Appendix). Outcome indicators were tracked through existing surveillance mechanisms, including the Youth Risk Behavior Surveillance System and Behavioral Risk Factor Surveillance System. CDC combined and analyzed performance-measure data annually and used aggregate data summaries to assess overall progress of the Steps program (16-18).
The following results were obtained from performance measure reports CDC received from the 40 Steps communities. For interventions implemented during 2003 through 2006, communities reported generic names for interventions, evidence-based sources, population sector receiving the intervention, and diseases or risk factors each intervention addressed. For example, a community may have reported that it implemented diabetes self-management education classes (intervention) on the basis of evidence of effectiveness reported in the Community Guide to Preventive Services (source of evidence) for community members (sector) diagnosed with diabetes (disease) who were overweight or obese (risk factor). By 2006, Steps communities had implemented approximately 1,500 interventions; 94% of the interventions were evidence-based, and 74% addressed 2 or more diseases or risk factors. The most common interventions implemented during 2003 through 2006 targeted individuals (Table 1).
Beginning in 2007, when Steps communities shifted their focus to the implementation of PSE change strategies, performance measure reporting also included the number and type of strategies implemented in each sector. By this time, all of the communities had implemented interventions that addressed 2 or more diseases or risk factors; 85% addressed all risk factors, 93% implemented at least 1 intervention at all levels of the SEM, and 85% addressed access to health care or quality of care. Steps communities implemented approximately 2,300 PSE change strategies during 2007 through 2010 (Table 2).
Fruit and vegetable promotion
A large urban area implemented a countywide community gardens project to increase access to affordable local produce. This Steps community partnered with a university cooperative extension service to provide outreach and training to residents interested in starting a community garden. The project resulted in the creation of 31 neighborhood produce gardens with 1,085 participating gardeners. Partnerships were established with food pantries and other emergency food providers, and thousands of pounds of produce were donated. The project also led to policy changes; project staff worked with the city council and city planning agency to pass new zoning legislation. Their success led to implementation of 7 additional gardens that received a total of $30,000 in grants from local foundations and businesses.
School-based health education policy
One of the school-based interventions implemented by a Steps community involved a policy that added the health education curriculum Planet Health to the academic curriculum in 16 middle schools, reaching 4,200 students. The Planet Health curriculum was chosen because it has been shown to decrease rates of obesity and disordered eating behaviors among girls, significantly reduce time spent watching television for boys and girls, and increase fruit and vegetable intake, knowledge of nutrition, and healthy activities among students (19). Students learned about the benefits of good nutrition and physical activity while building skills in language arts, health, math, science, and social studies. School teachers and staff received annual training on integrating this curriculum into daily classroom learning activities. After 1 year of using this curriculum, approximately 90% of teachers reported that it had a positive effect on both students' and their own health habits.
Comprehensive worksite wellness initiative
One Steps community established a "Healthiest Business Challenge" that awarded points for worksite participation in initiatives such as walking programs, healthy-meeting food policies, stairwell-use campaigns, and establishment or modification of written smoke-free worksite policies. Challenge winners received awards during a Chamber of Commerce meeting and recognition in a local business journal. During the first 3 years of the initiative, 34 businesses and approximately 6,750 employees completed the challenge. Approximately 80% of the participating businesses implemented or upgraded at least 1 worksite policy related to nutrition, physical activity, or smoking cessation. This initiative is now being conducted throughout the state (20).
Policy for health care providers
A partnership between a Steps community and a hospital resulted in implementation of a policy requiring health care providers to focus on patients' tobacco use and cessation efforts. Providers from various disciplines were trained to follow the 5 A's model (21), a 2-minute strategy shown to increase tobacco-use cessation by encouraging health care providers to 1) ask patients abouat tobacco use, 2) advise them to quit, 3) assess patients' willingness to quit, 4) assist in cessation attempts, and 5) arrange for patient follow-up. Providers were also encouraged to refer patients to the state quitline, where intensive counseling was provided. Approximately 550 health care providers were trained on the 2-minute intervention, and the hospital changed its patient intake and education forms to reflect the new process. As a result of the new policy, total calls to the quitline from health care provider referrals quadrupled in 1 year, and calls increased 50% compared with those made in a neighboring county with similar demographics.
Researchers have increasingly recognized the importance of PSE change to achieve widespread and sustainable improvements in health behaviors (22-24). They also acknowledge the challenges of implementing strategies (25-28). Successful PSE change strategy implementation often depends on the assumption that voters and stakeholders, who are often large corporate entities, will accept serious changes to the food, school, and built environments. Schools and local governments encounter budgetary barriers to implementing these strategies (eg, mandating physical and nutrition education in schools often requires hiring new staff, offering healthier cafeteria foods costs more, and constructing bicycle paths and sidewalks requires transportation funds that are already limited). Legal and constitutional hurdles can restrict efforts to place limits on advertising of unhealthy products, and contractual concerns may thwart attempts to change vending practices, especially in schools that benefit from proceeds. Steps communities encountered these challenges, yet they were able to collectively implement approximately 2,300 PSE change strategy interventions during 2007 through 2010.
Steps communities also experienced challenges identifying short-term health outcomes. Long-term health outcomes associated with their work are unknown. Systemwide changes in health behavior (eg, students at an elementary school who collectively increased their fruit and vegetable consumption) were not always observed in the short term. Data and descriptions of interventions were based on self-report, and although validity and reliability concerns associated with this method of data collection arose, CDC staff conducted comprehensive, in-person site visits and validated intervention descriptions and the existence of all reported interventions.
Steps was instrumental in transforming the way CDC addresses chronic disease prevention. It was the first CDC program to fund local jurisdictions to implement PSE change strategies. Communities throughout the United States have replicated Steps policy initiatives, such as menu-labeling requirements, trans-fat bans, and smoke-free housing. In Philadelphia, the Steps Program supported the most comprehensive menu-labeling legislation that existed in 2009 (29). In 2008, Boston Steps helped the city became one of the first in the nation to ban the use of artificial trans-fats in restaurants and grocery stores (10). The Steps program in Clark County, Washington, helped implement one of the first countywide smoke-free housing policies for government-owned residences in the United States (14).
Since 2008, CDC has been designing and implementing programs that support PSE change strategy based on the Steps Model, including Strategic Alliance for Health in 2008 and Communities Putting Prevention to Work in 2010. Most recently, CDC launched the Community Transformation Grant program to increase opportunities for state-supported communities, counties, cities, territories, and tribes to implement integrated, sustainable PSE change-focused strategies, based in part on the Steps Model.
Although policies, programs, and other interventions that promote healthy eating, physical activity, and smoke-free public places have resulted from the growing recognition of their importance, they are often being implemented despite the lack of evidence for their effectiveness. As CDC continues to fund communities to do this work, the evidence base for these types of strategies will grow. Although CDC has supported publications that document some Steps communities' successes and lessons learned (30-34), more reports in the scientific literature are needed.
