Taking physical activity to the streets: The popularity of ciclovia and open streets initiatives in the US

As a way to reduce chronic diseases associated with increasingly sedentary lifestyles, the Centers for Disease Control and Prevention advocates community-wide initiatives promoting physical activity. One such initiative gaining popularity in the US is the Ciclovía, or Open Streets initiative, where city streets are opened to residents for physical activity and closed to motorized traffic.1 Open Streets gained international prominence in Bogota, Colombia, and are viewed by policy makers and health and community advocates as being beneficial to social, environmental, and community health.2 The interest in initiatives is demonstrated by the increase in the number of events within and across the US in recent years; between 2008 and 2013, over 90 US cities hosted at least one event.3 The cities hosting events range in size from small suburban towns to large metropolitan areas and also range in socioeconomic demographics and diversity.4 Open Streets offer a potentially effective public health intervention in a variety of contexts

Effect of environmental conditions on perceived psychological restorativeness of coastal parks

We investigated the hypothesis that perception of psychological restorativeness during visits to coastal parks is modified by objective and perceived environmental conditions. Visitors (n=1,153) to California beaches completed a survey on perceived weather, environmental quality, and perceived restorativeness. We used generalized ordinal logistic models to estimate the association between environmental parameters and odds of perceiving higher levels of restorativeness. Visitors perceived greater restorativeness at beaches when ambient temperatures were at or below mean monthly temperatures and during low tides. The odds of perceiving the environment as more psychologically restorative were three times greater when visiting on days defined by government policy as having good air quality (OR=3.25; CI: 1.69–6.28). Visitors’ perception of air (OR=1.56; CI: 1.14–2.18) and water quality (OR=1.78; CI: 1.28–2.49) also affected perceived restorativeness; with perceived healthy days more restorative. Warmer temperatures with less space due to sea level rise and poor environmental quality will restrict restorative experiences in recreational facilities designed for urban populations

Social Ecological Constraints to Park Use in Communities With Quality Access

Evidence correlates physical activity, psychological restoration, and social health to proximity to parks and sites of recreation. The purpose of this study was to identify perceived constraints to park use in low-income communities facing significant health disparities, with access to underutilized parks. We used a series of focus groups with families, teens, and older adults in neighborhoods with similar demographic distribution and access to parks over 125 acres in size. Constraints to park use varied across age groups as well as across social ecological levels, with perceived constraints to individuals, user groups, communities, and society. Policies and interventions aimed at increasing park use must specifically address barriers across social ecological levels to be successful

Social Ecological Constraints to Park Use in Communities with Proximate Park Access

Evidence correlates physical activity, psychological restoration, and social health to proximity to parks and sites of recreation. The purpose of this study was to identify perceived constraints to park use in low-income communities facing significant health disparities, but with proximate access to underutilized parks. The authors used a series of focus groups with families, teens, and older adults in neighborhoods with similar demographic distribution and parks over 125 acres in size. Constraints to park use varied across age groups as well as across social ecological levels, with perceived constraints to individuals, user groups, communities, and society. Policies and interventions aimed at increasing park use must specifically address constraints across social ecological levels to be successful

Target population involvement in urban ciclovias: a preliminary evaluation of St. Louis Open Streets

Ciclovias are active street events when roads are open to walkers, cyclists, and families and closed to automobiles. Over 70 cities in the USA have implemented ciclovias to promote physical activity. The authors evaluated four events during 2010 to determine what activities participants perform and who is attending. For two ciclovia events in St. Louis, Missouri, observation reports of activities, gender, and age of 1,452 participants were collected, and 82 adults were interviewed via direct approach. The survey covered six domains: physical activity, travel to event, sense of community, marketing, economic impact, and demographics. Each event occurred within the city, along multiple streets. Domains were selected from Ciclovia Recreativa developed by Ciclovia Bogota, Pan American Health Organization, and CDC. Additional questions addressed city-specific goals and matched similar evaluations in other cities.Over 50%of participants met CDC-defined weekly minute thresholds for physical activity. Participants, primarily (980 %) middle class, college educated, and white, were not representative of the majority minority city population, which has high rates of poverty, and low percentage of college graduates. Cities must work with residents to increase low-income minority population participation in ciclovia-based physical activity

Occupational sitting and weight status in a diverse sample of employees in Midwest metropolitan cities, 2012–2013

INTRODUCTION: Few studies have examined the association between occupational sitting and body mass index (BMI). There is a particular lack of evidence among diverse populations. The objective of this study was to quantify the association between self-reported occupational sitting time and BMI by sex and race, independent of levels of occupational and leisure-time physical activity. METHODS: In 2012 and 2013, participants residing in 4 Missouri metropolitan areas were interviewed via telephone. The interview included questions on sociodemographic characteristics and time spent sitting at work. Multinomial logistic regressions were used to examine the association between occupational sitting and BMI between men and women and between black and white women. RESULTS: Overall 1,891 participants (66.9% women, 29.5% black) provided complete data. Median daily time spent by both men and women in occupational sitting was 180 minutes (interquartile range, 30 to 360 minutes); most participants were overweight (32.3%) or obese (33.6%). After adjusting for potential confounders, we found that black women in 3 categories of sitting time (31–180 minutes, 181–360 minutes, and >360 minutes) were approximately 2.5 times as likely (P for trend, .02) to be obese as black women who reported sitting for 30 minutes or less, independent of occupational and leisure-time physical activity. This association was not seen among white women. No significant associations were found among men. CONCLUSION: Occupational sitting is associated with an increased likelihood of obesity among black women, independent of occupational and leisure-time physical activity. Areas of future research include evaluating associations among various occupations and industries, assessing the association in prospective cohorts, and exploring the feasibility of worksite interventions that target sitting

Open streets initiatives in the U.S. : Closed to traffic, open to physical activity

Background: The ciclovía, or open streets concept, is a community level physical activity promotion strategy where streets are closed to motorized traffic and open for individuals to engage in PA. This paper presents an overview of such initiatives in the U.S. to understand their potential in PA promotion, comparing event and city characteristics. Methods: We searched ciclovía and open streets initiatives held in 2011 in the U.S. using internet searches, publication databases, social media, and personal contacts. We extracted data on the each initiative’s frequency, route length, attendance, evaluation procedures, and sociodemographic characteristics of host cities. Results: Our search yielded 47 U.S. cities with open streets in 2011. Cities were diverse in sociodemographic characteristics. Route lengths ranged from a few blocks to 51 miles and event frequency ranged from annual to monthly. Reporting number of participants for events was sporadic. Few events conducted formal evaluations. Conclusion: The number of U.S. cities hosting open streets is increasing. The sociodemographics of the host cities suggest a potential to increase physical activity in populations at risk for developing chronic diseases through these initiatives. However, further evaluation is required. Identifying successful promotion and evaluation tactics would boost the health promotion potential of these initiatives

Exploring neighborhood environments and active communting in Chennai, India

Few studies assess built environment correlates of active commuting in low-and-middle-income countries (LMICs), but the different context could yield distinct findings. Policies and investments to promote active commuting remain under-developed in LMICs like India, which grapples with traffic congestion, lack of activity-supportive infrastructure, poor enforcement of traffic rules and regulations, air pollution, and overcrowding. This cross-sectional study investigated associations between home neighborhood environment characteristics and active commuting in Chennai, India. Adults (N = 370, 47.2% female, mean age = 37.9 years) were recruited from 155 wards in the metropolitan area of Chennai in southern India between January and June 2015. Participants self-reported their usual mode of commute to work, with responses recoded into three categories: (1) multi-modal or active commuting (walking and bicycling; n = 56); (2) public transit (n = 52); and (3) private transport (n = 111). Environmental attributes around participants’ homes were assessed using the Neighborhood Environment Walkability Scale for India (NEWS-India). Associations between environmental characteristics and likelihood of active commuting and public transit use were modeled using logistic regression with private transport (driving alone or carpool) as the reference category, adjusting for age, gender, and household car ownership. Consistent with other international studies, participants living in neighborhoods with a mix of land uses and a transit stop within a 10-minute walk from home were more likely to use active commuting (both p < 0.01). Land-use mix was significantly associated with the use of public transit compared to private transport (adjusted odds ratio (aOR) = 5.2, p = 0.002). Contrary to findings in high-income countries, the odds of active commuting were reduced with improved safety from crime (aOR = 0.2, p = 0.003), aesthetics (aOR = 0.2, p = 0.05), and street connectivity (aOR = 0.2, p = 0.003). Different environmental attributes were associated with active commuting, suggesting that these relationships are complex and may distinctly differ from those in high-income countries. Unexpected inverse associations of perceived safety from crime and aesthetics with active commuting emphasize the need for high-quality epidemiologic studies with greater context specificity in the study of physical activity in LMICs. Findings have public health implications for India and suggest that caution should be taken when translating evidence across countries
