Prevalence of metabolic syndrome among Vietnamese adult employees.

BACKGROUND AND AIMS: Metabolic syndrome (MtS) is associated with increased risk of many health disorders, especially cardiovascular diseases. In Vietnam, study examining MtS is meager and especially lacking for the workforce. We estimated the prevalence of MtS and its associated factors among Vietnamese employees. METHODS AND RESULTS: We analyzed secondary data of annual health check of employees of 300 Vietnamese companies from the Vinmec Healthcare System. We used three definitions for MtS: International Diabetes Federation (IDF), National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), and NCEP ATP III-Asia. Of 57,997 participants evaluated, 48.5 % were males and 66.2 % were younger than 40 years old. The unadjusted MtS prevalence was 8.4 % (IDF), 10.2 % (NCEP ATP III), and 16.0 % (NCEP ATP III-Asia). The age-sex adjusted prevalence of MtS (NCEP ATP III-Asia) was 21.8 % (95 % confidence interval (CI): 21.4 %, 22.2 %). MtS prevalence increased with age, reached 49.6 % for age ≥60. The aging related increase was more remarkable in females than males (prevalence ratio (PR) (95 % CI) for age ≥60 comparing to age <30 years old in males vs. females was 4.0 (3.6, 4.3) vs. 20.1 (17.7, 22.9)). High blood triglyceride (83.4 %) and abdominal obesity (74.5 %) were the predominant contributors to MtS. CONCLUSION: In this relatively young Vietnamese working population, 16 % had MtS with high triglyceride and abdominal obesity being the predominant contributors. These findings emphasize the need for developing effective high triglyceride and abdominal obesity prevention and control programs to curb the emerging epidemic of metabolic disorders in the workforce.

The association of park use and park perception with quality of life using structural equation modeling.

Introduction: The literature is limited on the impact of neighborhood parks on quality of life (QoL) and the mechanism linking them. Methods: In this paper, we applied the structural equation model to data from a cross-sectional sample of 650 participants in low-income communities of New York City, we examined the associations of neighborhood park use vs. park perception and QoL, and whether these associations were mediated through self-reported perceived stress. We also examined whether park use mediated the relationship between park perception and QoL. Results: We found that park use had a significant but weak association with QoL (standardized ß = 0.08, 95% confidence interval (CI): 0.02, 0.15, p = 0.02), but this relationship was not mediated by self-reported stress. Park perception was more strongly associated with QoL than park use (standardized ß = 0.23, 95% CI: 0.16, 0.30, p < 0.01), and this was partly mediated by self-reported stress (indirect effect- standardized ß = 0.08, 95% CI: 0.03, 0.13, p < 0.01) and, to a lesser extent, by park use (indirect effect- standardized ß = 0.01, 95% CI: 0.00, 0.02, p = 0.01). Discussion: Having well-perceived parks appears to be an important factor for QoL independent of park use, suggesting that quality parks may benefit everyone in a community beyond park users. This strengthens the argument in favor of increasing park investment as a strategy to improve population wellbeing.

Implementation of Physical Activity Programs for Rural Cancer Survivors: Challenges and Opportunities.

Physical activity after cancer diagnosis has been consistently associated with improvements in quality of life and prognosis. However, few cancer survivors meet physical activity recommendations, and adherence is even lower among those living in rural settings. The purpose of this quasi-experimental study was to evaluate the implementation of a clinic-based physical activity program for cancer survivors at a rural community oncology setting. We also examined changes in quality-of-life measures among 24 cancer survivors participating in the physical activity program and described challenges and opportunities to optimize future implementation efforts in rural settings. Significant pre- to post-program improvements in fatigue (5.5 to 6.8; p = 0.03), constipation (7.7 to 9.0; p = 0.02), pain (6.7 to 8.0; p = 0.007), and sleep quality (p = 0.008) were observed. Participants also reported improved nausea, stamina, depression, stress, and overall physical health after participation in the physical activity program, although the differences were not statistically significant (all p-values > 0.13). However, the reach of the physical activity program was limited, with only 0.59% of cancer survivors participating. Fidelity to the physical activity program was relatively high, with 72.7% of survivors participating in at least five classes. Our findings suggest that physical activity programs in oncological settings may need tailoring to effectively reach rural cancer survivors.

The Role of the Physical and Social Environment in Observed and Self-Reported Park Use in Low-Income Neighborhoods in New York City.

Physical and social environments of parks and neighborhoods influence park use, but the extent of their relative influence remains unclear. This cross-sectional study examined the relationship between the physical and social environment of parks and both observed and self-reported park use in low-income neighborhoods in New York City. We conducted community- (n = 54 parks) and individual-level (n = 904 residents) analyses. At the community level, observed park use was measured using a validated park audit tool and regressed on the number of facilities and programmed activities in parks, violent crime, stop-and-frisk incidents, and traffic accidents. At the individual level, self-reported park use was regressed on perceived park quality, crime, traffic-related walkability, park use by others, and social cohesion and trust. Data were collected in 2016-2018 and analyzed in 2019-2020. At the community level, observed park use was negatively associated with stop-and-frisk (ß = -0.04; SE = 0.02; p < 0.05) and positively associated with the number of park facilities (ß = 1.46; SE = 0.57; p < 0.05) and events (ß = 0.16; SE = 0.16; p < 0.01). At the individual level, self-reported park use was positively associated with the social cohesion and trust scale (ß = 0.02; SE = 0.01; p < 0.05). These results indicate that physical and social attributes of parks, but not perceptions of parks, were significantly associated with park use. The social environment of neighborhoods at both community and individual levels was significantly related to park use. Policies for increasing park use should focus on improving the social environment of parks and surrounding communities, not only parks' physical attributes. These findings can inform urban planning and public health interventions aimed at improving the well-being of residents in low-income communities.

Recruitment and Retention Strategies for Community-Based Longitudinal Studies in Diverse Urban Neighborhoods.

Longitudinal, natural experiments provide an ideal evaluation approach to better understand the impact of built environment interventions on community health outcomes, particularly health disparities. As there are many participant engagement challenges inherent in the design of large-scale community-based studies, adaptive and iterative participant engagement strategies are critical. This paper shares practical lessons learned from the Physical Activity and Redesigned Community Spaces (PARCS) study, which is an evaluation of the impact of a citywide park renovation initiative on physical activity, psychosocial health, and community well-being. The PARCS study, although ongoing, has developed several approaches to improve participant engagement: building trust with communities, adapting the study protocol to meet participants' needs and to reflect their capacity for participation, operational flexibility, and developing tracking systems. These strategies may help researchers anticipate and respond to participant engagement challenges in community-based studies, particularly in low-income communities of color.

Factors related to completion of referral among women with suspected cervical cancer and dysplasia in Tanzania.

OBJECTIVE: To investigate completion of referral among women with suspected cervical cancer in Tanzania. METHODS: Retrospective cohort study of 196 women referred from two healthcare clinics to Ocean Road Cancer Institute, Dar es Salaam, between March 2016 and June 2018. Women with precancerous lesions or suspected cancer were interviewed about their knowledge and perception of cervical cancer and referred for follow-up. RESULTS: Most participants were unable to name symptoms (55.1%), prevention methods (88.3%), or treatments (59.0%), although 79.1% rated the disease as severe. Women who came for routine early detection were less likely to complete referral than those who did not (odds ratio [OR], 0.18; 95% confidence interval [CI], 0.05-0.70). Women who knew someone who died from cervical cancer were 5.40 times more likely to complete referral than those who did not. Knowing someone with cervical cancer was a predictor of referral completion in three multivariate models: OR, 5.62 (95% CI, 2.20-14.38); 4.34 (1.64-11.47); and 4.61 (1.72-12.36). Having severe symptoms was a predictor of non-completion in two models: 0.30 (0.12-0.75) and 0.35 (0.14-0.87). CONCLUSION: Patient-directed interventions should include education involving survivors of cancer and dysplasia, whereas system-directed interventions should utilize reminders to increase referral completion.

Walk with a Doc-a Call to Action for Physician-Led Walking Programs.

PURPOSE OF REVIEW: An abundance of data supports the health benefits of physical activity, social connectedness, and spending time outdoors. Yet, a majority of Americans are living lives that are sedentary, lonely, and not connected with nature. We have three primary goals in writing this paper. First, we will review the well-documented health challenges arising from a sedentary, isolated lifestyle. Second, we will discuss the benefits of walking as a primary means of increasing physical activity. Finally, we will shine a light on the exponential success of Walk with a Doc, a national non-profit organization. Walk with a Doc focuses on bringing physician-led enthusiasm into our communities by organizing regular doctor-led walks in the outdoors; as well as Walk with a Future Doc, which encourages medical students to start their own Walk with a Doc programs. RECENT FINDINGS: The Physical Activity Guidelines for Americans share that physical activity is an important action that people of all ages can take to improve their health. These guidelines recommend that adults partake in at least 150 min of moderate aerobic physical activity. Currently, only 23% of Americans are achieving this amount of aerobic activity. In addition, recent data suggest that 3 in 4 people are lonely, a significant social determinant of health. Finally, over half of all Americans spend fewer than 5 h outside each week. Walk with a Doc and Walk with a Future Doc are having an enormous impact on combating the negative effects of these health challenges. An evaluability assessment was completed in 2018 showing Walk with a Doc attendees felt the program increased their physical activity and their social connections, with a majority of Walk with a Doc gatherings occurring in nature. Physicians and other Walk with a Doc program leaders also reported high levels of satisfaction with their participation in Walk with a Doc. As teammates in this healthcare fight, we are all painfully aware of the crisis on our hands. Of our patients, 70% are overweight or obese, nearly 80% of us are not getting enough physical activity, with all of this leading to billions of dollars in healthcare costs. Adding fuel to the fire, our doctors are burning out because of it. Today, we want to share what we have learned to be an extremely viable solution. The solution has the capacity to save 5 million lives and $68 billion dollars per year. Additionally, it is bolstering the job satisfaction and happiness of our providers. Personally, it turned my life around in 2005, and since then, it is now greater than 560 communities around the USA (and 34 other countries). We call it, simply, Walk with a Doc.

Correlates of accelerometry non-adherence in an economically disadvantaged minority urban adult population.

OBJECTIVES: The purpose of this study was to examine socio-demographic and psychosocial correlates of non-adherence to an accelerometry protocol in an economically disadvantaged urban population. DESIGN: Cross-sectional study. METHODS: We analyzed 985 New York City adult participants aged 18-81 years from the Physical Activity and Redesigned Community Spaces (PARCS) study. Participants were asked to wear a hip-worn ActiGraph GT3X-BT accelerometer for one week. Adherent accelerometer wear was defined as ≥3 days of ≥8 h/day of wear over a 7-day period and non-adherent accelerometry wear was defined as any wear less than adherent wear from returned accelerometers. Examined correlates of adherence included sociodemographic and psychosocial characteristics (e.g., general physical/mental health-related quality of life, self-efficacy for exercise, stress, sense of community/neighborhood well-being, and social cohesion). RESULTS: From the total sample, 636 (64.6%) participants provided adherent wear and 349 (35.4%) provided non-adherent wear. In multivariable analysis, younger age (odds ratio [OR] = 0.63, 95% confidence interval [CI]: 0.53-0.75), poorer health-related quality of life (OR = 0.80, 95% CI: 0.65-0.98 for physical health and OR = 0.77, 95% CI: 0.62-0.94 for mental health), lower sense of community (OR = 0.79, 95% CI: 0.62-1.00) and current smoking status (OR = 1.97, 95% CI: 1.35-2.86) were associated with non-adherent wear. CONCLUSIONS: Non-adherent wear was associated with younger age, smoking, and lower self-reported physical/mental functioning and sense of community. This information can inform targeted adherence strategies to improve physical activity and sedentary behavior estimates from accelerometry data in future studies involving an urban minority population.

Lifetime Drinking Trajectories and Nonfatal Acute Myocardial Infarction.

BACKGROUND: The relation of lifetime drinking trajectories to coronary heart disease is not well understood. METHODS: Cases hospitalized for a nonfatal acute myocardial infarction (AMI) and healthy population-based controls matched on age and sex completed a physical examination and an interview covering known AMI risk factors and a detailed lifetime drinking history. Distinct lifetime drinking trajectories based on ounces of ethanol consumed per decade between ages 10 and 59 years were derived and characterized according to lifetime drinking patterns associated with each. Sex-specific multiple logistic regression analyses were conducted to estimate AMI risk among participants who never drank regularly compared to lifetime drinking trajectories and risk associated with distinct trajectories among former and current drinkers. RESULTS: Two lifetime drinking trajectories were derived, early peak and stable. Early peak trajectories were characterized by earlier onset of regular drinking, less frequent drinking, more drinks per drinking day, fewer total drinks, more frequent drunkenness per drinking year, and reduced alcohol intake or abstention by middle age. Never drinking regularly, reported by significantly more women than men, was associated with significantly higher AMI risk than stable lifetime drinking trajectories among men and in the sex-combined analysis of former drinkers only. Compared to stable lifetime drinking trajectories, early peak trajectories were associated with significantly higher AMI risk among male former drinkers, among sex-combined former drinkers, and among female current drinkers. CONCLUSIONS: Epidemiological studies of alcohol and health in populations over age 35 may have underestimated the impact of heavy episodic drinking during adolescence and emerging adulthood on the cardiovascular system.

Educational Opportunities for Down-Staging Breast Cancer in Low-Income Countries: an Example from Tanzania.

While more than 90% of breast cancer patients in western countries survive for at least 5 years, the survival rate in Tanzania is less than 45% because of late stage at presentation. The aim of this study was to identify patient and health system factors related to early or late stages of a breast cancer diagnosis. The study was conducted at the Ocean Road Cancer Institute (ORCI) in Dar es Salaam, Tanzania, and included interviews with 196 breast cancer patients diagnosed with early (stage I/II, n = 44) or late (stage III/IV, n = 152) stage who were referred to ORCI from January 2016 to August 2018. The questionnaire elicited information regarding disease history, sociodemographics, barriers to navigating the health system, and patient attitudes towards breast cancer. More early-stage patients (54.5%) stated history of previous breast examinations before their initial diagnosis compared to late-stage patients (19.7%) (p = < 0.001). Financial restraints were cited more often as barriers to diagnosis among late-stage presentation patients (55.7%) compared to early-stage patients (35.5%) (p = 0.047). Patients who were diagnosed at late-stage (47.5%) were also more likely to state time restraints as significant barriers to their diagnosis than early-stage patients (25.8%) (p = 0.041). Although the late diagnosis of breast cancer will take immense efforts of policy workers to resolve, this study offers significant opportunities for making immediate health system changes through patient and physician education that can aid in reducing diagnosis delay in Tanzania other low-income developing countries, and low-income communities within the USA.

Healthy lifestyle and breast cancer risk: A case-control study in Morocco.

BACKGROUND: Some modifiable risk factors have been independently associated with breast cancer (BC) risk in Moroccan women, but no studies have investigated their joint association. This study aimed to investigate the association between a Healthy Lifestyle Index (HLI) score and BC risk among Moroccan women. METHODS: In this case-control study, 300 incident BC cases and 300 controls, matched by age and area of residence were recruited. Cases were women newly-diagnosed with histopathologically-confirmed BC at the University Hospital in Fez, Morocco. Controls were randomly selected healthy women recruited from 6 primary health centers in Fez. HLI scores developed within this study were assigned to participants based on 11 factors (red and processed meat, white meat, cream, cheese, fish, fruit and vegetables, physical activity, BMI, smoking, alcohol consumption, and breastfeeding), where 0 was given to unhealthy and 0.5 or 1 to healthy levels of each factor. Conditional and unconditional logistic regression models were used to assess the association between HLI scores and BC risk. RESULTS: Mean of HLI scores were 8.1 (±1.1) and 9.0 (±0.9) in cases and controls, respectively, p < 0.01. After adjusting for potential confounders, one-point increment in the HLI score was associated with 56% (95% CI, CI: 39-68%), 49% (95% CI: 30-63%), and 59% (95% CI: 40-72%) lower risks of BC in all, premenopausal, and postmenopausal women, respectively. CONCLUSION: High HLI scores were associated with decreased risk of BC in Moroccan women. These findings suggest that BC prevention policies should include strategies for engaging Moroccan women in healthy lifestyles.

Evaluating a Newly Developed System for Electronic Medical Records in Tanzania: An Example of the Experience in Low-Income Countries.

The introduction of electronic medical records (EMRs) in health systems in high-income countries has streamlined access to care and quality of patient information. However, in low-income countries such as Tanzania, EMR remains in its initial stages. The aim of this study was to compare completeness of patient information in the paper medical records (PMRs) with that of the newly implemented EMRs. Using hospital records of newly diagnosed breast cancer patients treated at the Ocean Road Cancer Institute, demographic, diagnostic, and treatment data of 328 patients between January 2017 and April 2018 were abstracted and compared between PMRs and EMRs. The results showed that demographic information variables were documented significantly more in EMRs (occupation, 98.5%) compared to PMRs (occupation, 43.3%) (P < .001). However, diagnostic and treatment information variables were much less likely to be reported in EMRs (full blood panel, 8.2%) than PMRs (full blood panel:=, 93%) (P < .001.) The results showed that EMR utilization corresponded with a marked decrease in the overall documentation rate of patient information compared to the standard PMRs. Multiple barriers affected EMR use. A major one was the lack of EMR connectivity across health systems in the country. Future studies should focus on uncovering the barriers and facilitators to EMR utilization, health care workers perception of available EMR systems, and better ways to improve lifetime sustainability of EMR systems in Tanzania and similar low-income countries.

Feasibility of using pedometers in a state-based surveillance system: 2014 Arizona Behavioral Risk Factor Surveillance System.

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.

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.

Achieving Equity in Physical Activity Participation: ACSM Experience and Next Steps.

There is clear and consistent evidence that regular physical activity is an important component of healthy lifestyles and fundamental to promoting health and preventing disease. Despite the known benefits of physical activity participation, many people in the United States remain inactive. More specifically, physical activity behavior is socially patterned with lower participation rates among women; racial/ethnic minorities; sexual minority youth; individuals with less education; persons with physical, mental, and cognitive disabilities; individuals >65 yr of age; and those living in the southeast region of the United States. Many health-related outcomes follow a pattern that is similar to physical activity participation. In response to the problem of inequities in physical activity and overall health in the United States, the American College of Sports Medicine (ACSM) has developed a national roadmap that supports achieving health equity through a physically active lifestyle. The actionable, integrated pathways that provide the foundation of ACSM's roadmap include the following: 1) communication-raising awareness of the issue and magnitude of health inequities and conveying the power of physical activity in promoting health equity; 2) education-developing educational resources to improve cultural competency for health care providers and fitness professionals as well as developing new community-based programs for lay health workers; 3) collaboration-building partnerships and programs that integrate existing infrastructures and leverage institutional knowledge, reach, and voices of public, private, and community organizations; and 4) evaluation-ensuring that ACSM attains measurable progress in reducing physical activity disparities to promote health equity. This article provides a conceptual overview of these four pathways of ACSM's roadmap, an understanding of the challenges and advantages of implementing these components, and the organizational and economic benefits of achieving health equity.

The Physical Activity and Redesigned Community Spaces (PARCS) Study: Protocol of a natural experiment to investigate the impact of citywide park redesign and renovation.

BACKGROUND: The built environment plays a critical role in promoting physical activity and health. The association between parks, as a key attribute of the built environment, and physical activity, however, remains inconclusive. This project leverages a natural experiment opportunity to assess the impact of the Community Parks Initiative (CPI), a citywide park redesign and renovation effort in New York City, on physical activity, park usage, psychosocial and mental health, and community wellbeing. METHODS: The project will use a longitudinal design with matched controls. Thirty intervention park neighborhoods are socio-demographically matched to 20 control park neighborhoods. The study will investigate whether improvements in physical activity, park usage, psychosocial and mental health, and community wellbeing are observed from baseline to 3 years post-renovation among residents in intervention vs. control neighborhoods. DISCUSSION: This study represents a rare opportunity to provide robust evidence to further our understanding of the complex relationship between parks and health. Findings will inform future investments in health-oriented urban design policies and offer evidence for addressing health disparities through built environment strategies.

Disparities in Adolescents' Residence in Neighborhoods Supportive of Physical Activity - United States, 2011-2012.

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 approaches(†) to increase physical activity by improving neighborhood supports for physical activity.(§) 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.

Strategic Priorities for Physical Activity Surveillance in the United States.

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.
