ABSTRACT Even though there is increasing evidence that the built environment (BE) has an influence on leisure-time physical activity (LTPA), little is known about this relationship in developing countries. The objective of this study was to assess the associations between objective built environment characteristics and LTPA.
A cross-sectional multilevel study was conducted in 27 neighborhoods in which 1315 adults aged 18-65 years were surveyed. An adapted version of the IPAQ (long version) was used to assess LTPA. Objective BE characteristics were obtained using Geographic Information Systems. Associations were assessed using multilevel polytomous logistic regression.
Compared with inactive people, those who resided in neighborhoods with the highest tertile dedicated to parks (7.4% to 25.2%) were more likely to be regularly active (POR = 2.05, 95% CI = 1.13-3.72; P = 0.021). Those who resided in neighborhoods with presence of TransMilenio stations (mass public transportation system) were more likely to be irregularly active (POR = 1.27, 95% CI = 1.07-1.50, P = 0.009) as compared with inactive people.
These findings showed that park density and availability of TransMilenio stations at neighborhood level are positively associated with LTPA. Public health efforts to address physical inactivity should consider the potential influences of urban planning and mass public transportation systems on health.

    ABSTRACT: Leisure-time physical activity is a complex behavior influenced by factors at multiple levels. To examine the associations between intrapersonal, interpersonal, environmental factors and leisure-time walking (LTW) and leisure-time physical activities (LTPA), excluding walking. We also examined the moderating effect of sociodemographic characteristics on these associations. A cross-sectional study was conducted with 1,461 adults from Curitiba, Brazil (63.7% women). LTW and LTPA were assessed through the International Physical Activity Questionnaire (IPAQ), and a cutoff point of ≥150min/wk was used. Associations were examined through multilevel logistic regressions. LTW was positively associated with self-efficacy, enjoyment, social support from family and friends, presence of public places for leisure and neighborhood aesthetics. LTPA was associated with self-efficacy, enjoyment, social support from family and friends, safety from crime and neighborhood aesthetics. Safety from crime was a predictor of LTPA among older adults only. Factors at multiple levels were associated with LTW and LTPA. Interventions to promote LTPA would likely benefit from considering personal, social and environmental factors and different levels of influence.

    ABSTRACT: Past studies have suggested that a link between health outcomes and green space is due to increased levels of physical activity of individuals living in areas with more green space. We found a positive association between green space and physical activity levels. The odds of achieving the recommended amount of physical activity was 1.27 (95% CI: 1.13-1.44) for people living in the greenest quintile in England compared to those living in the least green quintile, after controlling for individual and environmental factors. However, no association was found between green space and types of physical activity normally associated with green space. An association was found with other types of physical activity (gardening and do-it-yourself, and occupational physical activity). These findings suggest that although there is a positive association between physical activity and green space it may not be explained by individuals using green space for recreation.

    ABSTRACT: Physical activity (PA) has consistently been associated with perceived environmental characteristics. To examine the association between perceived environmental attributes and various forms of PA in Curitiba, Brazil. A cross-sectional phone survey of adults was conducted in 2008 (n=2097). The questionnaire included environmental perceptions and PA. Principal components analysis was used to identify groups of perceived environmental attributes. Multivariate methods tested the associations of PA with perceived environment characteristics. Perceptions of moderate and high personal safety were positively associated with walking for transportation (53.0%, 53.1% vs. 47.3%, both adjusted ORs [aOR]=1.5). Number of destinations within a 10-minute walk (4 and >6 vs. <3) was positively associated with bicycling for transportation (7.8%, 9.9% vs.4.8%, aOR=2.5). Perception of high accessibility was positively associated with MVPA during leisure time (35.1% vs. 19.1, aOR=1.7) and meeting recommendations for total PA (58.7% vs. 45.1%, aOR=1.4). Perception of high quality of the pedestrian space (57.3% vs. 46.5%, aOR=1.4) and moderate levels of personal safety (54.3% vs. 47.6%, aOR=1.3) were also positively associated with meeting recommendations for total PA. Different environmental attributes were associated with different PA outcomes, suggesting that these relationships are complex and may differ from those in high-income countries.
