BACKGROUND: The HEART score uses elements from patient History, Electrocardiogram, Age, Risk Factors, and Troponin to obtain a risk score on a 0- to 10-point scale for predicting acute coronary syndromes (ACS). This investigation seeks to improve on the HEART score by proposing the HEARTS(3) score, which uses likelihood ratio analysis to give appropriate weight to the individual elements of the HEART score as well as incorporating 3 additional 'S' variables: Sex, Serial 2-hour electrocardiogram, and Serial 2-hour delta troponin during the initial emergency department valuation. METHODS: This is a retrospective analysis of a prospectively acquired database consisting of 2148 consecutive patients with non-ST-segment elevation chest pain. Interval analysis of likelihood ratios was performed to determine appropriate weighting of the individual elements of the HEART(3) score. Primary outcomes were 30-day ACS and myocardial infarction. RESULTS: There were 315 patients with 30-day ACS and 1833 patients without ACS. Likelihood ratio analysis revealed significant discrepancies in weight of the 5 individual elements shared by the HEART and HEARTS(3) score. The HEARTS(3) score outperformed the HEART score as determined by comparison of areas under the receiver operating characteristic curve for myocardial infarction (0.958 vs 0.825; 95% confidence interval difference in areas, 0.105-0.161) and for 30-day ACS (0.901 vs 0.813; 95% confidence interval difference in areas, 0.064-0.110). CONCLUSION: The HEARTS(3) score reliably risk stratifies patients with chest pain for 30-day ACS. Prospective studies need to be performed to determine if implementation of this score as a decision support tool can guide treatment and disposition decisions in the management of patients with chest pain.

Problem/Conditions: Cardiovascular disease (CVD), including coronary heart disease (CHD) and stroke, is the leading cause of death in the United States, and state rates of CVD vary by state and by region of the country. Several behavioral risk factors (i.e., overweight, physical inactivity, smoking, hypertension, and diabetes mellitus) and preventive practices (i.e., weight loss and smoking cessation) are associated with the development of CVD and also vary geographically. This summary displays and analyzes geographic variation in the prevalences of selected CVD risk factors. Reporting Period: 1994 (1992 for prevalence of hypertension). Description of System: The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based random-digit-dialing telephone survey of noninstitutionalized adults aged >/=18 years; 50 states and the District of Columbia participated in BRFSS in 1994, and 48 states and the District of Columbia participated in 1992. Methods: Several different analyses were conducted: a) analysis of state risk factor and preventive practice prevalences by sex and race (i.e., black and white); b) mapping; c) cluster analysis; d) correlations of state prevalence rates by sex and race; and e) regression of state risk factor prevalences on state CHD and stroke mortality rates. Results: Mapping the prevalence of selected CVD risk factors and preventive health practices indicates substantial geographic variation for black and white men and women, as confirmed by cluster analysis. Data for blacks are limited by small sample size, especially in western states. Geographic clustering is found for physical inactivity, smoking, and risk factor combinations. Risk factor prevalences are generally lower in the West and higher in the East. White men and white women are more similar in state risk factor rates than other race-sex pairs; white women and black women ranked second in similarity. State prevalences of physical inactivity and hypertension are strongly associated with state mortality rates of CVD. Interpretation: Geographic patterns of risk factor prevalence suggest the presence (or absence) of sociocultural environments that promote (or inhibit) the given risk factor or preventive behavior. Because the risk factors examined in this summary are associated with CVD, further exploration of the reasons underlying observed geographic patterns might be useful. The BRFSS will continue to provide geographic data about cardiovascular health behaviors with a possible emphasis on more data-based small-area analyses and mapping. This will permit states to more adequately monitor trends that affect the burden of CVD in their regions and the United States. Mapping also facilitates the exploration of patterns of morbidity, health-care use, and mortality, as well as the epidemiology of risk factors. Finally, by identifying those segments of the population with high levels of these risk factors and lower levels of the preventive health practices, public health personnel can better allocate resources and target intervention efforts for the prevention of CVD.

Context: Overweight and obesity are increasing in the United States. Changes in diet and physical activity are important for weight control.Objectives: To examine the prevalence of attempting to lose or to maintain weight and to describe weight control strategies among US adults.Design: The Behavioral Risk Factor Surveillance System, a random-digit telephone survey conducted in 1996 by state health departments. Setting The 49 states (and the District of Columbia) that participated in the survey.Participants: Adults aged 18 years and older (N = 107 804).Main Outcome Measures: Reported current weights and goal weights, prevalence of weight loss or maintenance attempts, and strategies used to control weight (eating fewer calories, eating less fat, or using physical activity) by population subgroup.Results: The prevalence of attempting to lose and maintain weight was 28.8% and 35.1 % among men and 43.6% and 34.4% among women, respectively. Among those attempting to lose weight, a common strategy was to consume less fat but not fewer calories (34.9% of men and 40.0% of women); only 21.5% of men and 19.4% of women reported using the recommended combination of eating fewer calories and engaging in at least 150 minutes of leisure-time physical activity per week. Among men trying to lose weight, the median weight was 90.4 kg with a goal weight of 81.4 kg. Among women, the median weight was 70.3 kg with a goal weight of 59.0 kg.Conclusions: Weight loss and weight maintenance are common concerns for US men and women. Most persons trying to lose weight are not using the recommended combination of reducing calorie intake and engaging in leisure-time physical activity 150 minutes or more per week.

Introduction: This systematic economic review examined the cost-benefit and cost-effectiveness of park, trail, and greenway infrastructure interventions to increase physical activity or infrastructure use., Methods: The search period covered the date of inception of publications databases through February 2022. Inclusion was limited to studies that reported cost-benefit or cost-effectiveness outcomes and were based in the U.S. and other high-income countries. Analyses were conducted from March 2022 through December 2022. All monetary values reported are in 2021 U.S. dollars., Results: The search yielded 1 study based in the U.S. and 7 based in other high-income countries, with 1 reporting cost-effectiveness and 7 reporting cost-benefit outcomes. The cost-effectiveness study based in the United Kingdom reported $23,254 per disability-adjusted life year averted. The median benefit-to-cost ratio was 3.1 (interquartile interval=2.9-3.9) on the basis of 7 studies., Discussion: The evidence shows that economic benefits exceed the intervention cost of park, trail, and greenway infrastructure. Given large differences in the size of infrastructure, intervention costs and economic benefits varied substantially across studies. There was insufficient number of studies to determine the cost-effectiveness of these interventions., (Published by Elsevier Inc.)

Background: Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries., Methods: We used data from the Global Observatory for Physical Activity (GoPA!) 2015 and 2020 surveys. Comprehensive searches were performed for each country to determine the level of development of their PA surveillance, policy, and research, and the findings were verified by the GoPA! Country Contacts. Trends were analyzed based on the data available for both survey years., Results: The global 5-year progress in all 3 indicators was modest, with most countries either improving or staying at the same level. PA surveillance, policy, and research improved or remained at a high level in 48.1%, 40.6%, and 42.1% of the countries, respectively. PA surveillance, policy, and research scores decreased or remained at a low level in 8.3%, 15.8%, and 28.6% of the countries, respectively. The highest capacity for PA promotion was found in Europe, the lowest in Africa and low- and lower-middle-income countries. Although a large percentage of the world's population benefit from at least some PA policy, surveillance, and research efforts in their countries, 49.6 million people are without PA surveillance, 629.4 million people are without PA policy, and 108.7 million live in countries without any PA research output. A total of 6.3 billion people or 88.2% of the world's population live in countries where PA promotion capacity should be significantly improved., Conclusion: Despite PA is essential for health, there are large inequalities between countries and world regions in their capacity to promote PA. Coordinated efforts are needed to reduce the inequalities and improve the global capacity for PA promotion.

Physical activity has become an integral component of public health systems modeling the public health core functions of assessment, policy development, and assurance. However, people with disabilities have often not been included in public health efforts to assess, develop policies, or evaluate the impact of physical activity interventions to promote health and prevent disease among people with disabilities. Addressing the core function of assessment, current physical activity epidemiology, and surveillance among people with disabilities across the globe highlights the paucity of surveillance systems that include physical activity estimates among people with disabilities. The status of valid and reliable physical activity measures among people with condition-specific disabilities is explored, including self-report measures along with wearable devices, and deficiencies in measurement of physical activity. The core functions of policy development and assurance are described in the context of community-based intervention strategies to promote physical activity among people with disabilities. The identification of research gaps in health behavior change, policy, and environmental approaches to promoting physical activity among people with disabilities is explored, along with recommendations based on the principles of inclusive and engaged research partnerships between investigators and the members of the disability community.

Approximately 1·5 billion people worldwide live with a physical, mental, sensory, or intellectual disability, about 80% of which are in low-income and middle-income countries. This Series paper provides a global overview of the prevalence, benefits, and promotion policies for physical activity for people living with disabilities (PLWD). PLWD are 16-62% less likely to meet physical activity guidelines and are at higher risk of serious health problems related to inactivity than people without disabilities. Meta-analyses have shown that physical activity has beneficial effects on cardiovascular fitness (average standardised mean difference [SMD] 0·69 [95% CI 0·31-1·01]), musculoskeletal fitness (0·59 [0·31-0·87]), cardiometabolic risk factors (0·39 [0·04-0·75]), and brain and mental health outcomes (0·47 [0·21-0·73]). These meta-analyses also show that health benefits can be achieved even with less than 150 min of physical activity per week, and suggest that some physical activity is better than none. Meta-analyses of interventions to increase physical activity for PLWD have reported effect sizes ranging from SMD 0·29 (95% CI 0·17-0·41, k=10) to 1·00 (0·46-1·53, k=10). There is increasing awareness among policy makers of the needs of PLWD for full participation in physical activity. Physical activity action plans worldwide must be adequately resourced, monitored, and enforced to truly advance the fundamental rights of PLWD to fully participate in physical activity., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2021 Elsevier Ltd.

Purpose: A novel automatic discontinuation policy implemented within an antimicrobial stewardship program (ASP) is described, and results of an evaluation of the policy's effects on antibiotic usage are reported., Methods: A retrospective, before-and-after study was conducted at an 800-bed, tertiary care, academic teaching hospital to evaluate selected antibiotic usage outcomes in both intensive care unit (ICU) and non-ICU adult patients targeted for ASP interventions before and after implementation of an automatic discontinuation of antibiotics policy (ADAP) authorizing the ASP team to automatically halt antibiotic therapy in cases involving inappropriate duplicate antimicrobial coverage or excess duration of therapy. The primary outcome was total days of antibiotic therapy. Secondary outcomes included excess days of therapy and rates of 30-day readmission, Clostridioides difficile infection, and multidrug-resistant infection., Results: There were no statistically significant differences in group demographics or clinical characteristics. The most common indication for antibiotics was hospital-acquired pneumonia, and the most common reason for ASP intervention was excess duration of therapy. The mean total number of antibiotic days per patient was reduced from 7.6 days in the pre-ADAP group to 6.6 days in the post-ADAP group (p < 0.05). The mean number of excess days of antibiotics was similarly reduced, from 2.3 days to 1.5 days, after implementation of the ADAP (p < 0.05)., Conclusion: Adoption of an ADAP-a more active approach to ASP interventions-was effective in reducing overall antibiotic usage and improving the efficiency of the ASP., (© American Society of Health-System Pharmacists 2019.

Background: There is a paucity of studies, especially among diverse populations, demonstrating the effects of policy and environmental interventions to increase regular physical activity. The Grow Healthy Together Chattanooga project provided the opportunity to assess the impact of physical activity policy and environmental interventions on the physical activity among predominately African American children living in the inner city., Methods: Using the System for Observing Physical Activity and Recreation in Communities (SOPARC), the authors examined the physical activity of children along urban pedestrian/bike routes/trails and recreational park areas within the boundaries of the Grow Healthy Together Chattanooga communities. SOPARC data were collected at baseline (fall 2010/spring 2011) and repeated (spring 2014) in each community., Results: The SOPARC assessments yielded a total of 692 child/youth observations in 2010 and 806 observations in 2014. Children/youth observed in 2014 were greater than 2 times the odds of engaging in moderate/vigorous physical activity compared with their 2010 counterparts (odds ratio  = 2.75, 95% confidence interval, 1.43-5.32)., Conclusions: The present findings support the hypothesis that policy and environmental interventions can contribute to increased physical activity levels among children/youth over ∼3-year period. These results provide evidence that improved access to "urban" pedestrian/bicycle routes/trails appears to translate into increased opportunities for physical activity among inner city children/youth.

Introduction: Exercise is Medicine (EIM) is an initiative that seeks to integrate physical activity assessment, prescription, and patient referral as a standard in patient care. Methods to assess this integration have lagged behind its implementation., Purpose and Objectives: The purpose of this work is to provide a pragmatic framework to guide health care systems in assessing the implementation and impact of EIM., Evaluation Methods: A working group of experts from health care, public health, and implementation science convened to develop an evaluation model based on the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework. The working group aimed to provide pragmatic guidance on operationalizing EIM across the different RE-AIM dimensions based on data typically available in health care settings., Results: The Reach of EIM can be determined by the number and proportion of patients that were screened for physical inactivity, received brief counseling and/or a physical activity prescription, and were referred to physical activity resources. Effectiveness can be assessed through self-reported changes in physical activity, cardiometabolic biometric factors, incidence/burden of chronic disease, as well as health care utilization and costs. Adoption includes assessing the number and representativeness of health care settings that adopt any component of EIM, and Implementation involves assessing the extent to which health care teams implement EIM in their clinic. Finally, Maintenance involves assessing the long-term effectiveness (patient level) and sustained implementation (clinic level) of EIM in a given health care setting., Implications for Public Health: The availability of a standardized, pragmatic, evaluation framework is critical in determining the impact of implementing EIM as a standard of care across health care systems.

Objectives: Early determination of hospital discharge disposition status at an acute admission is extremely important for stroke management and the eventual outcomes of patients with stroke. We investigated the hospital discharge disposition of patients with stroke residing in Tennessee and developed a predictive tool for clinical adoption. Our investigational aims were to evaluate the association of selected patient characteristics with hospital discharge disposition status and predict such status at the time of an acute stroke admission., Methods: We analyzed 127,581 records of patients with stroke hospitalized between 2010 and 2014. Logistic regression was used to generate odds ratios with 95% confidence intervals to examine the factor outcome association. An easy-to-use clinical predictive tool was built by using integer-based risk scores derived from coefficients of multivariable logistic regression., Results: Among the 127,581 records of patients with stroke, 86,114 (67.5%) indicated home discharge and 41,467 (32.5%) corresponded to facility discharge. All considered patient characteristics had significant correlations with hospital discharge disposition status. Patients were at greater odds of being discharged to another facility if they were women; older; black; patients with a subarachnoid or intracerebral hemorrhage; those with the comorbidities of diabetes mellitus, heart disease, hypertension, chronic kidney disease, arrhythmia, or depression; those transferred from another hospital; or patients with Medicare as the primary payer. A predictive tool had a discriminatory capability with area under the curve estimates of 0.737 and 0.724 for derivation and validation cohorts, respectively., Conclusions: Our investigation revealed that the hospital discharge disposition pattern of patients with stroke in Tennessee was associated with the key patient characteristics of selected demographics, clinical indicators, and insurance status. These analyses resulted in the development of an easy-to-use predictive tool for early determination of hospital discharge disposition status.

Purpose: Develop strategic priorities to guide future physical activity surveillance in the United States., Methods: The Centers for Disease Control and Prevention and the American College of Sports Medicine convened a scientific roundtable of physical activity and measurement experts. Participants summarized the current state of aerobic physical activity surveillance for adults, focusing on practice and research needs in three areas: 1) behavior, 2) human movement, and 3) community supports. Needs and challenges for each area were identified. At the conclusion of the meeting, experts identified one overarching strategy and five strategic priorities to guide future surveillance., Results: The identified overarching strategy was to develop a national plan for physical activity surveillance similar to the U.S. National Physical Activity Plan for promotion. The purpose of the plan would be to enhance coordination and collaboration within and between sectors, such as transportation and public health, and to address specific strategic priorities identified at the roundtable. These strategic priorities were used 1) to identify and prioritize physical activity constructs; 2) to assess the psychometric properties of instruments for physical activity surveillance; 3) to provide training and technical assistance for those collecting, analyzing, or interpreting surveillance data; 4) to explore accessing data from alternative sources; and 5) to improve communication, translation, and dissemination about estimates of physical activity from surveillance systems., Conclusion: This roundtable provided strategic priorities for physical activity surveillance in the United States. A first step is to develop a national plan for physical activity surveillance that would provide an operating framework from which to execute these priorities.

On the eve of the 2012 summer Olympic Games, the first Lancet Series on physical activity established that physical inactivity was a global pandemic, and global public health action was urgently needed. The present paper summarises progress on the topics covered in the first Series. In the past 4 years, more countries have been monitoring the prevalence of physical inactivity, although evidence of any improvements in prevalence is still scarce. According to emerging evidence on brain health, physical inactivity accounts for about 3·8% of cases of dementia worldwide. An increase in research on the correlates of physical activity in low-income and middle-income countries (LMICs) is providing a better evidence base for development of context-relevant interventions. A finding specific to LMICs was that physical inactivity was higher in urban (vs rural) residents, which is a cause for concern because of the global trends toward urbanisation. A small but increasing number of intervention studies from LMICs provide initial evidence that community-based interventions can be effective. Although about 80% of countries reported having national physical activity policies or plans, such policies were operational in only about 56% of countries. There are important barriers to policy implementation that must be overcome before progress in increasing physical activity can be expected. Despite signs of progress, efforts to improve physical activity surveillance, research, capacity for intervention, and policy implementation are needed, especially among LMICs., (Copyright © 2016 Elsevier Ltd.

Introduction: Exercise is Medicine™ (EIM) is an approach to clinic-based physical activity (PA) promotion. Study aims were to 1) assess the acceptability of current EIM protocols among healthcare providers (providers) and health and fitness professionals (fitness professionals); and 2) pilot test the resultant modified EIM protocols comparing patients referred to community PA programming with patients exposed to the EIM protocols alone., Methods: During 2012-2013 in Chattanooga, Tennessee, USA, 30/80 invited providers and 15/25 invited fitness professionals received training and provided feedback in the use of the EIM protocols. Following EIM use, feedback from providers and fitness professionals about acceptability of EIM protocols resulted in the adaptation of EIM protocols into the electronic health record. Subsequently, 50 providers and 8 fitness professionals participated in the intervention phase of the pilot study. Healthy and/or disease managed adults 18 years and older were enrolled with a sample of patients exposed to both the EIM protocols and community PA programming (EIM +) while another sample was exposed to the EIM protocols only (EIM). All patients were assessed for physical activity and Health-related Quality of Life. Measures were repeated ~ 3 months later for each patient., Results: Eighteen EIM + and 18 EIM participants were studied. The EIM + participants had a greater net increase in total PA (∆[Formula: see text] = + 250 min/week) vs. EIM participants (∆[Formula: see text] = - 38.6 min/week) (p = 0.0002)., Conclusions: EIM + participation significantly increased PA levels among participants, suggesting this approach significantly impacts the PA of inactive adults more than just EIM only.

Background: Despite overwhelming evidence of the health benefits of physical activity, most American youth are not meeting the 60 minutes per day recommendation for moderate- to vigorous-intensity physical activity (MVPA). Policy changes have the potential to bring about substantial increases in physical activity in youth, within school and community settings., Purpose: The purpose of this study was to quantify the increase in energy expenditure for school-based policies and built environment changes., Methods: Scientific literature reviews were consulted, and more than 300 published studies (1995-2011) in English were identified based on titles and abstracts. After an initial screening, 85 articles were included. Study quality was assessed, and the impact of various strategies for increasing physical activity in youth was estimated from objective measurements/direct observation., Results: Within school settings, the average minutes of MVPA gained per school day for studies in each intervention category were as follows: mandatory physical education (23 minutes); classroom activity breaks (19 minutes); afterschool activity programs (10 minutes); standardized physical education curricula (6 minutes more than traditional physical education); modified playgrounds (6 minutes); and modified recess (5 minutes more than traditional recess). Within community settings, significant MVPA was associated with active commuting (16 minutes) and park renovations (12 minutes), but proximity to parks had a small effect (1 minute). No conclusions could be drawn regarding joint-use agreements, because of a lack of studies quantifying their impact on energy expenditure., Conclusions: Of the various policies and built environment changes examined, the largest effects were seen with mandatory physical education, classroom activity breaks, and active commuting to school. Policymakers can use this information along with estimates of the cost, feasibility, and population reach, to identify the best options for increasing physical activity in youth., (Copyright © 2013 American Journal of Preventive Medicine.

Promotion of physical activity is a priority for health agencies. We searched for reviews of physical activity interventions, published between 2000 and 2011, and identified effective, promising, or emerging interventions from around the world. The informational approaches of community-wide and mass media campaigns, and short physical activity messages targeting key community sites are recommended. Behavioural and social approaches are effective, introducing social support for physical activity within communities and worksites, and school-based strategies that encompass physical education, classroom activities, after-school sports, and active transport. Recommended environmental and policy approaches include creation and improvement of access to places for physical activity with informational outreach activities, community-scale and street-scale urban design and land use, active transport policy and practices, and community-wide policies and planning. Thus, many approaches lead to acceptable increases in physical activity among people of various ages, and from different social groups, countries, and communities.

Background: Given sparse knowledge on dissemination, this study sought to explore key benefits, barriers and contextual factors that are perceived to be important to the adoption and implementation of the 'Community Guide's' evidence-based physical activity recommendations., Design: We conducted case studies in two states where extensive adoption and implementation of the Guide's recommendations have occurred and in two states where widespread dissemination has lagged. Interviews (n = 76) were semi-structured and included both quantitative and qualitative methods. Participant perceptions from the following areas were examined: (i) priority of physical activity, (ii) awareness of and ability to define the term 'evidence-based approaches' and (iii) awareness, adoption, facilitators, benefits, challenges and barriers to Guide adoption., Results: Key enabling factors among high capacity states included: funds and direction from the Centers for Disease Control and Prevention; leadership support; capable staff; and successful partnerships and collaborations. Restraining forces among low capacity states included: the Guide recommendations being too new; participants being too new to current job; lack of time and training on how to use the Guide recommendations; limited funds and other resources and lack of leadership., Conclusion: To be effective, we must gain an understanding of contextual factors when designing for dissemination.

Background: Regular physical activity has been demonstrated to protect against coronary heart disease, Type 2 diabetes mellitus, selected cancers, hypertension, obesity, and other chronic conditions. Therefore, the public health significance of promoting physical activity and preventing inactivity has become a well-established agenda for public health agencies at all levels., Methods: A secondary search of the literature, focusing on existing evidence reviews, was conducted to identify effective or promising public health physical activity interventions. Further examination of published evidence-based programs also was carried out to supplement the known evidence base. Intervention strategies were selected using criteria prescribed by each of the systematic reviews to yield categories of intervention effectiveness., Key Recommendations: The selected physical activity interventions conformed to the domains identified by The Guide to Community Preventive Services. Recommended evidenced-based strategies from within the domain of informational approaches include 2 exemplary community-wide campaigns; mass media campaigns, represented by VERB; and an emerging practice of delivery of short physical activity messages at key community sites. Exemplary representative behavioral/social interventions include social support through organized walking clubs/partners within communities. Exemplary environmental/policy approaches include creating/enhancing access to places for physical activity with informational outreach activities and the emerging strategy of community-wide policies and planning.

Background: Since overweight (25 < or = BMI < 30) and obesity (BMI > or = 30 Kg/m2) are associated with poor health-related quality of life (HRQOL) and regular physical activity is associated with higher levels of HRQOL, the authors examined the relationship between physical activity and HRQOL among overweight and obese adults (age > or = 18 years) residing in the United States., Methods: Using the 2005 BRFSS survey, they examined the independent relationship between recommended physical activity and measures of HRQOL developed by the Centers for Disease Control and Prevention among 283,562 adults age 18 years or older with overweight or obesity. Measures of physical activity, height, weight, and HRQOL were self-reported. Multivariable logistic regression was used to obtain odds ratios and 95% confidence intervals adjusted for age, race/ethnicity, sex, education, smoking status, chronic disease, and body-mass index., Results: The proportion of adults with overweight and obesity who attained recommended levels of physical activity had higher levels of HRQOL than physically inactive adults for all age, racial/ethnic, and sex groups. After multivariable adjustment, overweight and obese adults who met the recommended level of physical activity had higher levels of HRQOL than physically inactive adults across all age strata., Conclusions: These results highlight the HRQOL role that physical activity can have among overweight and obese persons despite their excess body weight.

The 20(th) century in the United States (U.S.) has experienced a dramatic increase in life expectancy among adult men and women, an increase unprecedented in the history of this country. As a result, the pattern of disease and conditions most responsible for death in the U.S. shifted during the past century from infectious diseases and unintentional injuries to the current array of the leading causes of mortality dominated by the chronic diseases. During this same period, daily lifestyle dramatically shifted from a life full of active living to one of inactivity. The argument has been made that in the case of human beings, there has been little or no change in our genotype within the past 50 years. However, there have been major changes documented in the living environment among economically developed societies during this same time period. Through the collection of epidemiologic, clinical, and experimental findings, evidence exists to suggest that physical inactivity is associated with the onset of chronic diseases of our day. Trends in physical inactivity evident through the monitoring of transport, recreational, sport, and purposeful activity have demonstrated that the current lifestyle of the 21(st) century has contributed substantially to the chronic disease burden in the U.S. and elsewhere. By addressing the domains that influence physical activity behaviors including the environment (both physical and social/cultural), health systems access, and behavioral correlates of physical activity and inactivity, the current chronic disease crisis can potentially be addressed.

Background: National surveillance data provide population-level estimates of physical activity participation, but generally do not include detailed subgroup analyses, which could provide a better understanding of physical activity among subgroups. This paper presents a descriptive analysis of self-reported regular physical activity among black adults using data from the 2003 Behavioral Risk Factor Surveillance System (n=19,189), the 2004 National Health Interview Survey (n=4263), and the 1999-2004 National Health and Nutrition Examination Survey (n=3407)., Methods: Analyses were conducted between January and March 2006. Datasets were analyzed separately to estimate the proportion of black adults meeting national physical activity recommendations overall and stratified by gender and other demographic subgroups., Results: The proportion of black adults reporting regular PA ranged from 24% to 36%. Regular physical activity was highest among men; younger age groups; highest education and income groups; those who were employed and married; overweight, but not obese, men; and normal-weight women. This pattern was consistent across surveys., Conclusions: The observed physical activity patterns were consistent with national trends. The data suggest that older black adults and those with low education and income levels are at greatest risk for inactive lifestyles and may require additional attention in efforts to increase physical activity in black adults. The variability across datasets reinforces the need for objective measures in national surveys.

Introduction: Estimates of participation in physical activity among Latinos are inconsistent across studies. To obtain better estimates and examine possible reasons for inconsistencies, we assessed 1) patterns of participation in various categories of physical activity among Latino adults, 2) changes in their activity patterns with acculturation, and 3) variations in their activity patterns by region of origin., Methods: Using data from four national surveillance systems (the National Health and Nutrition Examination Survey, 1999-2002; the Behavioral Risk Factor Surveillance System, 2003; the National Household Travel Survey, 2001; and the National Health Interview Survey Cancer Supplement, 2000), we estimated the percentage of Latinos who participated at least once per week in leisure-time, household, occupational, or transportation-related physical activity, as well as in an active pattern of usual daily activity. We reported prevalences by acculturation measures and region of origin., Results: The percentage of Latinos who participated in the various types of physical activity ranged from 28.7% for having an active level of usual daily activity (usually walking most of the day and usually carrying or lifting objects) to 42.8% for participating in leisure-time physical activity at least once per week. The percentage who participated in leisure-time and household activities increased with acculturation, whereas the percentage who participated in occupational and transportation-related activities decreased with acculturation. Participation in an active level of usual daily activity did not change significantly. The prevalence of participation in transportation-related physical activity and of an active level of usual daily activity among Latino immigrants varied by region of origin., Conclusion: Physical activity patterns among Latinos vary with acculturation and region of origin. To assess physical activity levels in Latino communities, researchers should measure all types of physical activity and the effects of acculturation on each type of activity.

Objectives: We explored the effect of disseminating evidence-based guidelines that promote physical activity on US health department organizational practices in the United States., Methods: We implemented a quasi-experimental design to examine changes in the dissemination of suggested guidelines to promote physical activity (The Guide to Community Preventive Services) in 8 study states; the remaining states and the Virgin Islands served as the comparison group. Guidelines were disseminated through workshops, ongoing technical assistance, and the distribution of an instructional CD-ROM. The main evaluation tool was a pre- and postdissemination survey administered to state and local health department staffs (baseline n=154; follow-up n=124)., Results: After guidelines were disseminated through workshops, knowledge of and skill in 11 intervention-related characteristics increased from baseline to follow-up. Awareness-related characteristics tended to increase more among local respondents than among state participants. Intervention adoption and implementation showed a pattern of increase among state practitioners but findings were mixed among local respondents., Conclusions: Our exploratory study provides several dissemination approaches that should be considered by practitioners as they seek to promote physical activity in the populations they serve.

Background: Evidence-based guidelines for promoting physical activity have been produced, yet sparse information exists on the dissemination of effective interventions. The purpose of this study was to better understand the dissemination of physical activity interventions across the United States, focusing particularly on evidence-based guidelines., Design: A cross-sectional study was conducted in the U.S. that was organized around a modified version of the diffusion of innovations theory., Setting/participants: Respondents (n=49) were the physical activity contact person (e.g., program administrator, health educator) in each state or territorial health department., Main Outcome Measures: Seven specific programs and policies relating to physical activity intervention were examined as dependent variables. Five additional domains--organizational climate, awareness, adoption, implementation, and maintenance--framed a set of independent variables., Results: The most important factor related to decision making was the availability of adequate resources. Most respondents (89.8%) were aware of evidence-based guidelines to promote physical activity. However, less than half of the respondents (41%) had the authority to implement evidence-based programs and policies. A minority of respondents reported having support from their state governor (35.4%) or from most of their state legislators (21.3%). Several key factors were associated with the adoption of evidence-based interventions, including the presence of state funding for physical activity, whether the respondent participated in moderate physical activity, presence of adequate staffing, and presence of a supportive state legislature., Conclusions: Awareness of the importance of promoting physical activity is relatively high in state and territorial health departments; however, the levels of internal support within the health department appear to outweigh any outside support from elected officials.

Purpose: The aim of the study is to compare national estimates of the incidence of self-reported all-cause and activity-specific injuries in adults with differing leisure-time physical activity levels., Methods: Data were analyzed from the 2000 to 2002 National Health Interview Survey. Leisure-time physical activity levels were categorized as active, insufficiently active, and inactive., Results: Age-adjusted incidences of all-cause injury did not differ by leisure-time physical activity level (active, 89.3/1000; 95% confidence interval [CI], 81.8-96.8; insufficiently active, 81.6/1000; 95% CI, 73.1-90.1; and inactive, 86.3/1000; 95% CI, 78.6-93.9). Active respondents (29.4/1000; 95% CI, 25.2-33.6) had a greater incidence of injury related to sport and leisure-time activities than inactive respondents (15.2/1000; 95% CI, 12.1-18.3), whereas inactive respondents (71.1/1000; 95% CI, 63.9-78.2) had a greater incidence of injury related to nonsport and non-leisure-time activities than active respondents (59.9/1000; 95% CI, 53.6-66.2). Results were unchanged after multivariate control for confounding factors., Conclusions: Although the incidence of sport and leisure-time injuries is associated with participation in leisure-time physical activity, no association was observed between leisure-time physical activity and overall injuries.

Background: Hypertension (HTN), which affects more than 65 million Americans, is associated with poor health-related quality of life (HRQOL). Regular physical activity (PA) has been shown to reduce blood pressure and is associated with higher levels of HRQOL., Methods: Using self-reports from 60,321 hypertensive adults age 18 y or older who participated in the 2003 Behavioral Risk Factor Surveillance Survey, we examined the independent relationship between engaging in recommended levels of moderate or vigorous PA and four measures of HRQOL developed by the Centers for Disease Control and Prevention., Results: For all age and racial/ethnic groups and both sexes, the proportion of hypertensive adults with 14 or more unhealthy days (physical or mental) in the past month was significantly lower among those who attained recommended levels of PA than among physically inactive adults., Conclusions: Participation in regular PA is one of several lifestyle strategies available to control and prevent HTN. These results suggest that PA is associated with higher levels of HRQOL among adults with HTN and highlight the importance of health programs that promote participation in regular PA.

Background: Although a number of environmental and policy interventions to promote physical activity are being widely used, there is sparse systematic information on the most effective approaches to guide population-wide interventions., Methods: We reviewed studies that addressed the following environmental and policy strategies to promote physical activity: community-scale urban design and land use policies and practices to increase physical activity; street-scale urban design and land use policies to increase physical activity; and transportation and travel policies and practices. These systematic reviews were based on the methods of the independent Task Force on Community Preventive Services. Exposure variables were classified according to the types of infrastructures/policies present in each study. Measures of physical activity behavior were used to assess effectiveness., Results: Two interventions were effective in promoting physical activity (community-scale and street-scale urban design and land use policies and practices). Additional information about applicability, other effects, and barriers to implementation are provided for these interventions. Evidence is insufficient to assess transportation policy and practices to promote physical activity., Conclusions: Because community- and street-scale urban design and land-use policies and practices met the Community Guide criteria for being effective physical activity interventions, implementing these policies and practices at the community-level should be a priority of public health practitioners and community decision makers.
