Peer Reviewed: Playground Renovations and Quality at Public Parks in Boston, Massachusetts, 1996-2007

Introduction

Recreational and transportation infrastructure can promote physical activity among children and adolescents. The Play Across Boston community-based research project sought to estimate and compare playground renovation rates across Boston areas before and after a playground quality assessment, to describe changes in playground quality among a subset of parks, and to document features of local transportation infrastructure around parks.

Methods

We used an observational pretest-posttest design to estimate playground renovation rates among 103 city-operated parks. Renovation rates were calculated on the basis of annual city Parks Department capital budgets from fiscal years 1996 through 2007. We used the same design to describe changes between a 2000 to 2001 baseline assessment of playground quality and a 2007 follow-up measured via observation of a subsample of 18 low-scoring parks in disadvantaged areas. We used χ ² analysis to compare percentages of playgrounds renovated across city areas before and after baseline assessment, logistic regression analysis to calculate odds ratios comparing renovation rates after baseline by city area, and paired t tests to compare playground quality at baseline and follow-up.

Results

Overall playground renovation rates before (29%) and after (34%) baseline assessment were similar. Parks scoring low on playground quality at baseline were renovated after baseline at a higher rate than high-scoring playgrounds. After accounting for baseline playground quality, parks in disadvantaged areas were renovated at a rate similar to those in other areas. Playground quality scores improved between baseline (mean, 38.3; 95% confidence interval, 35.3-41.3) and 2007 in a subsample of previously low-scoring parks in disadvantaged areas.

Conclusion

The findings of the 2007 follow-up assessment indicate an equitable rate of playground renovation across city areas according to need.     

Peer Reviewed: Pedometer Use Among Adults at High Risk of Type 2 Diabetes,Finland, 2007-2008

Introduction

A pedometer helps adults exercise more, but sedentary adults need instruction and advice to be motivated to use one. We conducted this qualitative study to describe the experiences of participants at high risk of type 2 diabetes who began using a pedometer.

Methods

A total of 74 people at high risk of type 2 diabetes participated in 6 months of group counseling. From April 2007 to April 2008, we collected data through questionnaires, theme interviews (n = 22) and video recordings of counseling sessions. From October 2007 through June 2008, we analyzed the data.

Results

Pedometers were useful tools for observing levels of exercise, setting personal goals for walking, and helping evaluate whether daily goals were met. Negative experiences were associated with functional failures, pedometers'' unsuitability for exercise other than walking, and the goal of 10,000 steps, which some participants considered too high.

Conclusions

Sedentary adults can be motivated to use a pedometer if we inform them that regular users find it a useful instrument for increasing their level of exercise. These adults should set realistic goals for walking and receive adequate instructions for using pedometers.     

Peer Reviewed: Nicotine Dependence and Its Risk Factors Among Users of Veterans Health Services, 2008-2009

Introduction

Tobacco use is the leading preventable cause of death in the United States and is disproportionately higher among veterans than nonveterans. We examined the prevalence of nicotine dependence and its associated risk factors among veterans who used health services in the US Department of Veterans Affairs (VA) system.

Methods

Using a case-control design, we compared all VA health service users in fiscal year 2008-2009 (N = 5,031,381) who received a nicotine dependence diagnosis with those who did not. Independent risk and protective factors associated with receiving a nicotine dependence diagnosis were identified using logistic regression analysis. We conducted subgroup analyses on 2 groups of particular policy concern: homeless veterans and veterans who served in Iraq and Afghanistan.

Results

Among all recent VA health service users, 15% (n = 749,353) received a diagnosis of nicotine dependence. Substance abuse, other mental health diagnoses, and homelessness were identified as major risk factors. Veterans who served in Iraq and Afghanistan were not found to be at increased risk compared to veterans from other war eras. Major risk and protective factors within the subgroups of homeless veterans and veterans who served in Iraq and Afghanistan were broadly similar to those in the general VA population.

Conclusion

Given that other studies have found higher rates of nicotine dependence among veterans, this risk behavior may be underdiagnosed in VA medical records. Veterans who are homeless or have mental health or substance abuse problems are at highest risk and should be targeted for smoking prevention and cessation interventions. These results support, in principle, efforts to integrate smoking cessation programs with mental health and homeless services.     

Peer Reviewed: Diabetes Self-Management Education in South Auckland,New Zealand, 2007-2008

Introduction

Self-management education programs seek to help patients realize that they are their own principal caregivers and that health care professionals are consultants who support them in this role. The aim of this study was to evaluate a diabetes self-management education program implemented as part of a district-wide approach in South Auckland, New Zealand, which has some of the highest prevalence rates for diabetes and is one of the most ethnically diverse and deprived regions of New Zealand.

Methods

Self-management attitudes and behaviors were monitored with the use of questionnaires before and after program implementation. Clinical outcomes such as hemoglobin A1c, body mass index, and blood pressure were also tracked before the program began and 3 months after the program ended. Participant focus groups and facilitator interviews were conducted to explore perceptions of the program.

Results

Participants showed improvement in attitudes toward their own ability to manage their diabetes; in diet, physical activity, and foot care; and in hemoglobin A1c levels 3 months after the end of participation. Participants also reduced their sense of isolation when dealing with their diabetes. However, catering to the needs of a multiethnic community is extremely resource-intensive because of the need to provide adequate language and cultural interpretation.

Conclusion

Self-management education can work in multiethnic, high-needs communities in New Zealand. Programs must ensure they enable the appropriate mechanisms and have appropriate resources to support the community''s needs.     

Peer Reviewed: Learning From the European Experience of Using Targets to Improve Population Health

Health targets have become a widely used instrument to promote population health. We describe the experience in England, where the use of targets has reached the most advanced stage of development, and other European countries. The experience demonstrates that targets may change the behavior of a health system, probably to a larger extent than many other policy instruments, if incentives are aligned correctly and if measures to deal with unintended effects are put in place.     

Peer Reviewed: Demographic and Geographic Differences in Exposure to Secondhand Smoke in Missouri Workplaces, 2007-2008

Introduction

African Americans, Hispanics, service and blue-collar workers, and residents of rural areas are among those facing higher rates of workplace secondhand smoke exposure in states without smokefree workplace laws. Consequently, these groups also experience more negative health effects resulting from secondhand smoke exposure. The objective of this study was to examine disparities in workplace secondhand smoke exposure in a state without a comprehensive statewide smokefree workplace law and to use this information in considering a statewide law.

Methods

We developed a logistic multilevel model by using data from a 2007-2008 county-level study to account for individual and county-level differences in workplace secondhand smoke exposure. We included sex, age, race, annual income, education level, smoking status, and rural or urban residence as predictors of workplace secondhand smoke exposure.

Results

Factors significantly associated with increased exposure to workplace secondhand smoke were male sex, lower education levels, lower income, living in a small rural or isolated area, and current smoking. For example, although the overall rate of workplace exposure in Missouri is 11.5%, our model predicts that among young white men with low incomes and limited education living in small rural areas, 40% of nonsmokers and 56% of smokers may be exposed to secondhand smoke at work.

Conclusion

Significant disparities exist in workplace secondhand smoke exposure across Missouri. A statewide smokefree workplace law would protect all citizens from workplace secondhand smoke exposure.     

Peer Reviewed: Use of Peer Groupings to Assess County Public Health Status

Introduction

The Community Health Status Indicators Project was undertaken to produce county-specific reports assessing the status of community health for local jurisdictions throughout the United States. To accomplish this assessment, the Community Health Status Indicators Project team selected peer groupings of counties to monitor and analyze the health of local communities relative to peer communities.

Methods

To identify peer counties, the project team used 5 categorical county demographic variables, a specified order for applying criteria, and a predetermined target for peer grouping size to subdivide counties into homogeneous subgroups called peer groupings.

Results

Eighty-eight peer groupings were developed with 14–58 counties in each. The average size of each peer grouping was 35 counties. All peer groupings included counties representing at least 6 states.

Discussion

Peer groupings are very useful for community health assessment. They convey the range of health status indicator values for similar counties, serve as a basis for expected numbers of reportable diseases, and provide a method for comparing communities with peer and U.S. medians. To maintain their usefulness, peer groupings must be updated periodically.     

Peer Reviewed: Simulating and Evaluating Local Interventions to Improve Cardiovascular Health

Numerous local interventions for cardiovascular disease are available, but resources to deliver them are limited. Identifying the most effective interventions is challenging because cardiovascular risks develop through causal pathways and gradual accumulations that defy simple calculation. We created a simulation model for evaluating multiple approaches to preventing and managing cardiovascular risks. The model incorporates data from many sources to represent all US adults who have never had a cardiovascular event. It simulates trajectories for the leading direct and indirect risk factors from 1990 to 2040 and evaluates 19 interventions. The main outcomes are first-time cardiovascular events and consequent deaths, as well as total consequence costs, which combine medical expenditures and productivity costs associated with cardiovascular events and risk factors. We used sensitivity analyses to examine the significance of uncertain parameters. A base case scenario shows that population turnover and aging strongly influence the future trajectories of several risk factors. At least 15 of 19 interventions are potentially cost saving and could reduce deaths from first cardiovascular events by approximately 20% and total consequence costs by 26%. Some interventions act quickly to reduce deaths, while others more gradually reduce costs related to risk factors. Although the model is still evolving, the simulated experiments reported here can inform policy and spending decisions.     

Peer Reviewed: School and Student Characteristics Associated With Screen-Time Sedentary Behavior Among Students in Grades 5-8, Ontario,Canada, 2007-2008

Introduction

We examined school and student characteristics associated with screen-time sedentary behavior.

Methods

We analyzed data collected from 2,449 students in grades 5 through 8 who attended 30 elementary schools in Ontario, Canada. We used multilevel logistic regression to examine the student- and school-level factors associated with moderate and high screen-time sedentary behavior.

Results

Moderate screen time did not vary significantly across schools. Student characteristics significantly associated with moderate screen time were sex, number of friends who are active, and parental encouragement of physical activity. High screen time did vary significantly across schools; school-level differences accounted for 12% of the variability in the odds of a student reporting high screen time. Students who attended a school in the more advanced phase of emphasizing participation in physical activity through school programs were less likely to report high screen time compared with students who attended schools in the earlier phase for this school-level indicator. Student characteristics significantly associated with high screen time were sex, parental encouragement of physical activity, parental support of physical activity, and race/ethnicity.

Conclusions

High levels of screen-time sedentary behavior are associated with both student characteristics and the characteristics of the school a student attends. Developing a better understanding of the school characteristics associated with sedentary behavior will be valuable for guiding the development of interventions to reduce sedentary behavior among youth populations.     

Peer Reviewed: The Latino Health Insurance Program: A Pilot Intervention for Enrolling Latino Families in Health Insurance Programs,East Boston,Massachusetts, 2006-2007

Background

Thirteen percent of Latinos in Massachusetts lack health insurance, the highest rate of any ethnic or racial group. Families without health insurance are more likely to be in poor or fair health, to lack a regular medical provider, and to not have visited a medical provider in the past year.

Context

The Latino Health Insurance Program is designed as a response both to the high rate of uninsurance among Latinos in Boston and to the multiple obstacles that keep Latino parents from applying for insurance for their families.

Methods

In 2006, we designed and implemented a culturally competent model of health insurance outreach, education, enrollment and maintenance, and referral for primary care and social services for Latino families.

Consequences

Year 1 results of the Latino Health Insurance Program are promising. Six community members were hired and trained as case managers. A total of 230 children and adults were enrolled or re-enrolled in health insurance programs and received other needed services. Retention was near 100% after 1 year.

Interpretation

The Latino Health Insurance Program may serve as a model health insurance access program that can be adapted by community-based organizations and also can be incorporated into public agency programs for Latinos and other immigrant and minority groups. The program continues to serve East Boston residents and was expanded in 2008.     

Peer Reviewed: Collaboration to Increase Colorectal Cancer Screening Among Low-Income Uninsured Patients

Background

Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States. CRC screening allows for prevention through the removal of precancerous lesions and early detection of cancer.

Community Context

Ride for Life Alaska (RFL), a nonprofit organization that raises funds to fight cancer, and the Anchorage Neighborhood Health Center (ANHC), which is Alaska''s largest community health center, joined efforts to provide CRC screening and outreach to an ethnically diverse group of low-income underinsured or uninsured patients residing in and around Anchorage, Alaska.

Methods

RFL and ANHC worked with gastroenterologists, medical practices, and pathology services to contribute pro bono and reduced-fee services for CRC screening. Information to patients was distributed through signs in the clinic, flyers, and the ANHC website.

Outcomes

CRC screening was increased in this population. During 2007-2009, there were 2,561 immunochemical fecal occult blood tests given to patients, and 1,558 were completed (61%); 24% were positive. Sixteen gastroenterologists, 4 medical practices, and 2 laboratories provided 111 follow-up colonoscopies and pathology services to patients identified through the CRC screening program who did not have other funding resources available for follow-up care.

Interpretation

This program provides a model for leveraging scarce screening resources by drawing on multiple partners to increase CRC screening. Recommendations for those seeking to initiate similar programs are to have memoranda of agreement in place and a clear scope of work for all participating people and organizations to avoid delays in program implementation; hire a screening care coordinator to manage patient care and collaborate with medical practices; and identify program champions who have the energy and persistence to craft such partnerships.     

Peer Reviewed: Using Social Marketing to Manage Population Health Performance

Population health can be affected by implementing pay-for-performance measures with key players. From a social marketing perspective, people (both consumers and managers) have choices and will do what they perceive enhances their own self-interest. The bottom-up focus of social marketing begins with an understanding of the people whose behaviors are targeted. Desired behavior results when people perceive that they will get more value than the cost of behaving and when the resulting offer is perceived to be better than what is obtainable through alternative choices. Incentives should be offered to consumers; managers should receive motivation for their own behavior and understand how to motivate relevant consumers. Pay can be monetary or nonmonetary, tangible or intangible. Everyone is paid for performance. Some are paid well enough to behave as desired; others are offered a poor rate of pay and choose not to behave.

Peer Reviewed: Novel Approach,Using End-of-Life Issues,for Identifying Items for Public Health Surveillance

Using end-of-life (EOL) issues to provide context, we introduce a novel approach to identify potential items for public health surveillance. Our method involved an environmental scan of existing EOL surveys and included the following steps: 1) consulting experts for advice on critical EOL topics, 2) identifying a broad sample of EOL surveys, and 3) using an abstraction tool to characterize surveys and survey items. We identified 36 EOL surveys; of these, 10 were state-based surveys. Of the 1,495 EOL items (range, 4 to 126 items per survey), 333 items could be classified in 1 of 11 topic areas of interest. Information on the surveys and these 333 items was entered into a database. As a result of this process, we identified topics for which many EOL items already exist and topics for which items should be developed. We describe the value of this approach and potential next steps for our project.     

Peer Reviewed: Changes in Receiving Preventive Care Services Among US Adults With Diabetes, 1997-2007

Introduction

Diabetes is a chronic disease that requires complex continuing medical care and patient self-management to reduce the risk of long-term complications. Receipt of multiple recommended preventive care services can prevent or delay diabetes-related complications such as blindness and lower-extremity amputations.

Methods

We analyzed 1997 and 2007 Behavioral Risk Factor Surveillance System data to examine change in rates of adults with diabetes receiving 4 essential preventive care services (influenza and pneumococcal vaccinations and annual foot and eye examinations).

Results

The overall age-adjusted rate of receiving all 4 of the preventive care services was 10% in 1997 but increased to 20% in 2007. Rates for receiving all 4 services increased significantly in all demographic subgroups except Hispanics.

Conclusion

Use of preventive care services is increasing, but most US adults with diabetes do not meet recommendations, and the problem is particularly pronounced among Hispanics. The need to receive preventive care services should continue to be emphasized in clinical and community settings to increase the percentage of adults with diabetes who receive them.     

Peer Reviewed: Reducing Cardiovascular Disease Risk Using Patient Navigators, Denver, Colorado, 2007-2009

Introduction

Early identification of cardiovascular disease (CVD) risk is important to reach people in need of treatment. At-risk patients benefit from behavioral counseling in addition to medical therapy. The objective of this study was to determine whether enhanced counseling, using patient navigators trained to counsel patients on CVD risk-reduction strategies and facilitate patient access to community-based lifestyle-change services, reduced CVD risk among at-risk patients in a low-income population.

Methods

We compared clinical characteristics at baseline and 12-month follow-up among 340 intervention and 340 comparison patients from community health centers in Denver, Colorado, between March 2007 and June 2009; all patients had a Framingham risk score (FRS) greater or equal to 10% at baseline. The intervention consisted of patient-centered counseling by bilingual patient navigators. At baseline and at 6-month and 12-month follow-up, we assessed health behaviors of intervention participants. We used an intent-to-treat approach for all analyses and measured significant differences by χ² and t tests.

Results

We found significant differences in several clinical outcomes. At follow-up, the mean FRS was lower for the intervention group (mean FRS, 15%) than for the comparison group (mean FRS, 16%); total cholesterol was lower for the intervention group (mean total cholesterol, 183 mg/dL) than for the comparison group (mean total cholesterol, 197 mg/dL). Intervention participants reported significant improvements in some health behaviors at 12-month follow-up, especially nutrition-related behaviors. Behaviors related to tobacco use and cessation attempts did not improve.

Conclusion

Patient navigators may provide some benefit in reducing risk of CVD in a similar population.     

Peer Reviewed: Development of a Community-Based Participatory Colorectal Cancer Screening Intervention to Address Disparities,Arkansas, 2008-2009

Background

The death rate from colorectal cancer is high and affects poor and medically underserved populations disproportionately. In the United States, health disparities are particularly acute in the Lower Mississippi River Delta region. Because many in the region have limited access to basic health care resources, they are not screened for cancer, even though screening is one of the most effective strategies to prevent colorectal cancer. Community-based participatory research is a promising approach to prevent colorectal cancer in this population.

Community Context

The Empowering Communities for Life program was implemented in 2 underserved counties in the Arkansas Lower Mississippi River Delta. The program arose from a 9-year partnership between the University of Arkansas for Medical Sciences and 9 cancer councils across Arkansas.

Methods

Empowering Communities for Life is a community-based participatory intervention designed to increase colorectal cancer screening in rural, underserved communities through fecal occult blood testing. Community and academic partners collaborated to develop research infrastructure, intervention materials and methods, and the assessment instrument.

Outcome

Project outcomes were strengthened community-academic partnerships, certification of community partners in conducting human subjects research, development of a randomized controlled design to test the intervention''s efficacy, an interactive PowerPoint presentation, an informational pamphlet, the certification of 6 lay health advisors and 22 role models to provide the intervention, and an assessment tool using an audience response system.

Interpretation

Lessons learned in working collaboratively with diverse groups include the importance of meeting face to face and listening.
