Feasibility of using pedometers in a state-based surveillance system: 2014 Arizona Behavioral Risk Factor Surveillance System
Florez-Pregonero A , Fulton JE , Dorn JM , Ainsworth BE . J Sport Health Sci 2018 7 (1) 34-41 Background: Despite their utility in accessing ambulatory movement, pedometers have not been used consistently to monitor physical activity in U.S. surveillance systems. This study was designed to determine the feasibility of using pedometers to assess daily steps taken in a sub-sample of adults from Maricopa County who completed the 2014 Arizona Behavioral Risk Factor Surveillance System Survey. Methods: Respondents were sent an Omron HJ324U pedometer, a logbook to record steps taken, and a walking questionnaire. The pedometer was worn for 7 days. Feasibility was assessed for acceptability (interest in study), demand (procedures followed correctly), implementation (time to complete study), and practicality (cost). Results: Acceptability was modest with 23.9% (830/3476) agreeing to participate. Among those participating (92.9%; 771/830), 50.1% (386/771) returned the logbook. Demand was modest with 39.3% (303/771) of logbooks returned with valid data. Implementation represented 5 months to recruit participants. The cost to obtain valid step-count data was USD61.60 per person. An average of 6363 ± 3049 steps/day were taken with most participants classified as sedentary (36.0%) or low active (35.6%). Conclusion: The feasibility of using pedometers in a state-based surveillance system is modest at best. Feasibility may potentially be improved with easy-to-use pedometers where data can be electronically downloaded. |
Increasing walking in the Hartsfield-Jackson Atlanta International Airport: The Walk to Fly Study
Fulton JE , Frederick GM , Paul P , Omura JD , Carlson SA , Dorn JM . Am J Public Health 2017 107 (7) e1-e7 OBJECTIVES: To test the effectiveness of a point-of-decision intervention to prompt walking, versus motorized transport, in a large metropolitan airport. METHODS: We installed point-of-decision prompt signage at 4 locations in the airport transportation mall at Hartsfield-Jackson Atlanta International Airport (Atlanta, GA) at the connecting corridor between airport concourses. Six ceiling-mounted infrared sensors counted travelers entering and exiting the study location. We collected traveler counts from June 2013 to May 2016 when construction was present and absent (preintervention period: June 2013-September 2014; postintervention period: September 2014-May 2016). We used a model that incorporated weekly walking variation to estimate the intervention effect on walking. RESULTS: There was an 11.0% to 16.7% relative increase in walking in the absence of airport construction where 580 to 810 more travelers per day chose to walk. Through May 2016, travelers completed 390 000 additional walking trips. CONCLUSIONS: The Walk to Fly study demonstrated a significant and sustained increase in the number of airport travelers choosing to walk. Providing signage about options to walk in busy locations where reasonable walking options are available may improve population levels of physical activity and therefore improve public health.

Developing point-of-decision prompts to encourage airport walking: The Walk to Fly Study
Frederick GM , Paul P , Bachtel Watson K , Dorn JM , Fulton J . J Phys Act Health 2016 13 (4) 419-27 BACKGROUND: Point-of-decision prompts may be appropriate to promote walking, instead of using a mechanized mode of transport, such as a train, in airports. To our knowledge, no current studies describe the development of messages for prompts in this setting. METHODS: In-person interviews were conducted with 150 randomly selected airport travelers who rode the train to their departure gate. Travelers reported various reasons for riding the train to their gate. They were asked about messages that would encourage them to walk. Exploratory factor analysis was conducted for reasons for riding the train. Confirmatory factor analysis was conducted for messages to encourage walking to the departure gate. RESULTS: Travelers reported not knowing walking was an option (23.8%), seeing others riding the train (14.4%), and being afraid of getting lost (9.2%) as reasons for riding the train. Many indicated that directional signs and prompts promoting walking as exercise would encourage them to walk instead of riding the train. CONCLUSIONS: Some reasons for riding the train in an airport may be modifiable by installing point-of-decision prompts. Providing directional signs to travelers may prompt them to walk to their gate instead of riding the train. Similar prompts may also be considered in other community settings. |
Disparities in adolescents' residence in neighborhoods supportive of physical activity - United States, 2011-2012
Watson KB , Harris CD , Carlson SA , Dorn JM , Fulton JE . MMWR Morb Mortal Wkly Rep 2016 65 (23) 598-601 In 2013, only 27% of adolescents in grades 9-12 met the current federal guideline for aerobic physical activity (at least 60 minutes of physical activity each day*), and sex and racial/ethnic disparities in meeting the guideline exist (1). The Community Preventive Services Task Force has recommended a range of community-level evidence-based approachesdagger to increase physical activity by improving neighborhood supports for physical activity. section sign To assess the characteristics of adolescents who live in neighborhoods that are supportive of physical activity, CDC analyzed data on U.S. children and adolescents aged 10-17 years (defined as adolescents for this report) from the 2011-2012 National Survey of Children's Health (NSCH). Overall, 65% of U.S. adolescents live in neighborhoods supportive of physical activity, defined as neighborhoods that are perceived as safe and have sidewalks or walking paths and parks, playgrounds, or recreation centers. Adolescents who were Hispanic and non-Hispanic black race/ethnicity; who lived in lower-income households, households with less educated parents, and rural areas; or who were overweight or obese were less likely to live in neighborhoods supportive of physical activity than were white adolescents and adolescents from higher income households, with a more highly educated parent, living in urban areas, and not overweight or obese. Within demographic groups, the largest disparity in the percentage of adolescents living in these neighborhoods was observed between adolescents living in households with a family income <100% of the Federal Poverty Level (FPL) (51%) and adolescents living in households with a family income ≥400% of the FPL (76%). Efforts to improve neighborhood supports, particularly in areas with a substantial percentage of low-income and minority residents, might increase physical activity among adolescents and reduce health disparities. |

Med Sci Sports Exerc 2016 48 (10) 2057-69 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: 1) identify and prioritize physical activity constructs, 2) assess the psychometric properties of instruments for physical activity surveillance, 3) provide training and technical assistance for those collecting, analyzing, or interpreting surveillance data, 4) explore accessing data from alternative sources, and 5) 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. |

Evenson KR , Brown DR , Pearce E , Camplain R , Jernigan J , Epping J , Shepard DM , Dorn JM . Res Q Exerc Sport 2016 87 (2) 1-7 PURPOSE: From 1996 to 2013, a 6-day Physical Activity and Public Health Course for Practitioners has been offered yearly in the United States. An evaluation was conducted to assess the impact of the course on building public health capacity for physical activity and on shaping the physical activity and public health careers of fellows since taking the courses. METHOD: An evaluation quantified time that fellows spent in different course offerings and surveyed fellows. RESULTS: From 1996 to 2012, 410 fellows attended the course, and in 2013, 186 participated in the Web-based survey (56% response rate). The number of fellows attending the course ranged from 15 to 33 yearly. From 1996 to 2012, the course averaged 38 hr of instructional time that included topics on interventions and environment/policy work to increase physical activity, program evaluation, public health research, and health disparities. The course included consultations, collaborative work, and field-based experiences. Fellows who participated in the survey agreed that the course had a positive impact on the physical activity research or practice work they did (98%), met their expectations (96%), helped them with research/practice collaborations with other physical activity professionals (96%), assisted them in conducting higher-quality interventions/programs (95%), helped increase their professional networking in the field (93%), and had a positive impact on other work they did (91%). Following the course, 66% and 56% had further contact with faculty and other fellows, respectively. CONCLUSION: The Physical Activity and Public Health Course for Practitioners made important contributions toward building the capacity of physical activity and public health practitioners. |
Opportunities for public health to increase physical activity among youths
Piercy KL , Dorn JM , Fulton JE , Janz KF , Lee SM , McKinnon RA , Pate RR , Pfeiffer KA , Young DR , Troiano RP , Lavizzo-Mourey R . Am J Public Health 2015 105 (3) e1-e6 Despite the well-known benefits of youths engaging in 60 or more minutes of daily physical activity, physical inactivity remains a significant public health concern. The 2008 Physical Activity Guidelines for Americans (PAG) provides recommendations on the amount of physical activity needed for overall health; the PAG Midcourse Report (2013) describes effective strategies to help youths meet these recommendations. Public health professionals can be dynamic change agents where youths live, learn, and play by changing environments and policies to empower youths to develop regular physical activity habits to maintain throughout life. We have summarized key findings from the PAG Midcourse Report and outlined actions that public health professionals can take to ensure that all youths regularly engage in health-enhancing physical activity. |
Cancer prevention and worksite health promotion: time to join forces
Allweiss P , Brown DR , Chosewood LC , Dorn JM , Dube S , Elder R , Holman DM , Hudson HL , Kimsey CD Jr , Lang JE , Lankford TJ , Li C , Muirhead L , Neri A , Plescia M , Rodriguez J , Schill AL , Shoemaker M , Sorensen G , Townsend J , White MC . Prev Chronic Dis 2014 11 E128 The workplace is recognized as a setting that can profoundly influence workers’ health and well-being (1,2). The Centers for Disease Control and Prevention (CDC) workplace health promotion efforts address cancer prevention by focusing on cancer screening programs, community–clinical linkages, and cancer risk factors (eg, tobacco use, physical inactivity) that also influence risk for other chronic diseases (http://www.cdc.gov/workplacehealthpromotion/). Some efforts focus specifically on cancer; some focus on general chronic disease prevention. Additionally, the National Institute for Occupational Safety and Health (NIOSH), part of CDC, provides research and recommendations to address workplace hazards posed by chemicals that may increase cancer risk (http://www.cdc.gov/niosh/topics/cancer/policy.html). | Existing resources can be leveraged to expand the scope of workplace initiatives to address additional cancer risk factors and disparities. Changes to the physical and social characteristics of work environments are likely to have greater impact than health education alone (3). Given the aging US population (which is expected to result in a marked increase in the number of cancer diagnoses over the coming decades) and the prevalence of numerous risk factors among working-aged adults (4,5), a multifaceted approach to cancer prevention in the workplace is timely and needed. In addition, community-based prevention efforts may offer unrealized opportunities to reach vulnerable working populations who are not served by workplace health promotion programs. In this essay, we draw attention to a wide variety of available CDC resources and provide ideas for new efforts to advance primary cancer prevention among working adults. |
Vital signs: disability and physical activity - United States, 2009-2012
Carroll DD , Courtney-Long EA , Stevens AC , Sloan ML , Lullo C , Visser SN , Fox MH , Armour BS , Campbell VA , Brown DR , Dorn JM . MMWR Morb Mortal Wkly Rep 2014 63 (18) 407-13 BACKGROUND: Adults with disabilities are less active and have higher rates of chronic disease than the general population. Given the health benefits of physical activity, understanding physical activity, its relationship with chronic disease, and health professional recommendations for physical activity among young to middle-age adults with disabilities could help increase the effectiveness of health promotion efforts. METHODS: Data from the 2009-2012 National Health Interview Survey (NHIS) were used to estimate the prevalence of, and association between, aerobic physical activity (inactive, insufficiently active, or active) and chronic diseases (heart disease, stroke, diabetes, and cancer) among adults aged 18-64 years by disability status and type (hearing, vision, cognitive, and mobility). The prevalence of, and association between, receiving a health professional recommendation for physical activity and level of aerobic physical activity was assessed using 2010 data. RESULTS: Overall, 11.6% of U.S. adults aged 18-64 years reported a disability, with estimates for disability type ranging from 1.7% (vision) to 5.8% (mobility). Compared with adults without disabilities, inactivity was more prevalent among adults with any disability (47.1% versus 26.1%) and for adults with each type of disability. Inactive adults with disabilities were 50% more likely to report one or more chronic diseases than those who were physically active. Approximately 44% of adults with disabilities received a recommendation from a health professional for physical activity in the past 12 months. CONCLUSIONS: Almost half of adults with disabilities are physically inactive and are more likely to have a chronic disease. Among adults with disabilities who visited a health professional in the past 12 months, the majority (56%) did not receive a recommendation for physical activity. IMPLICATIONS FOR PUBLIC HEALTH: These data highlight the need for increased physical activity among persons with disabilities, which might require support across societal sectors, including government and health care. |
Central adiposity and subclinical cardiovascular disease in police officers
Baughman P , Fekedulegn D , Andrew ME , Joseph PN , Dorn JM , Violanti JM , Burchfiel CM . ISRN Obes 2013 2013 895687 Given the associations between obesity and cardiovascular disease (CVD), we evaluated a related but less well-established association between waist circumference and brachial artery reactivity (BAR), a functional measurement of subclinical CVD, where lower levels indicate dysfunction. Regression models examined trends in mean BAR across waist circumference tertiles in police officers, a high-stress occupational group with increased risk for CVD. Mean BAR decreased across increasing waist tertiles among men, but not women, and this association was stronger among officers who consumed more alcohol. Larger waist circumference may be associated with lower BAR, providing an opportunity for intervention prior to disease development. |

Ma CC , Burchfiel CM , Charles LE , Dorn JM , Andrew ME , Gu JK , Joseph PN , Fekedulegn D , Slaven JE , Hartley TA , Mnatsakanova A , Violanti JM . Am J Ind Med 2013 56 (11) 1341-51 BACKGROUND: We aimed to examine the association of objectively measured and self-reported sleep duration with carotid artery intima media thickness (IMT) among 257 police officers, a group at high risk for cardiovascular disease (CVD). METHODS: Sleep duration was estimated using actigraphic data and through self-reports. The mean maximum IMT was the average of the largest 12 values scanned bilaterally from three angles of the near and far wall of the common carotid, bulb, and internal carotid artery. Linear and quadratic regression models were used to assess the association of sleep duration with IMT. RESULTS: Officers who had fewer than 5 or 8 hr or more of objectively measured sleep duration had significantly higher maximum IMT values, independent of age. Self-reported sleep duration was not associated with either IMT measure. CONCLUSION: Attainment of sufficient sleep duration may be considered as a possible strategy for atherosclerosis prevention among police officers. |
Evaluating the prognostic value of positron-emission tomography myocardial perfusion imaging using automated software to calculate perfusion defect size
Williams BA , Dorn JM , Lamonte MJ , Donahue RP , Trevisan M , Leonard DA , Greene RS , Merhige ME . Clin Cardiol 2012 35 (11) E14-21 BACKGROUND: Myocardial perfusion imaging by positron-emission tomography (PET MPI) is regarded as a valid technique for the diagnosis of coronary artery disease (CAD), but the incremental prognostic value of PET MPI among individuals with known or suspected CAD is not firmly established. HYPOTHESIS: Myocardial perfusion defect sizes as measured by PET MPI using automated software will provide incremental prognostic value for cardiac and all-cause mortality. METHODS: This study included 3739 individuals who underwent rest-stress rubidium-82 PET MPI for the evaluation of known or suspected CAD. Rest, stress, and stress-induced myocardial perfusion defect sizes were determined objectively by automated computer software. Study participants were followed for a mean of 5.2 years for cardiac and all-cause mortality. Cox proportional hazards models were developed to evaluate the incremental prognostic value of PET MPI. RESULTS: A strong correlation was observed between perfusion defect sizes assessed visually and by automated software (r = 0.76). After adjusting for cardiac risk factors, known CAD, noncoronary vascular disease, and use of cardioprotective medications, stress perfusion defect size was strongly associated with cardiac death (P < 0.001). Rest perfusion defects demonstrated a stronger association with cardiac death (P < 0.001) than stress-induced perfusion defects (P = 0.01), yet both were highly significant. Similar patterns held for all-cause death. CONCLUSIONS: The current study is the largest to date demonstrating PET MPI provides incremental prognostic value among individuals with known or suspected CAD. Automated calculation of perfusion defect sizes may provide valuable supplementary information to visual assessment.
