Article Abstract
Background: Physical activity (PA) has consistently been associated with perceived environmental characteristics.
Objective: To examine the association between perceived environmental attributes and various forms of PA in Curitiba, Brazil.
Methods: 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.
Results: 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.
Conclusions: Different environmental attributes were associated with different PA outcomes, suggesting that these relationships are complex and may differ from those in high-income countries.
Introduction: Sports gains reflect the sports development of college students, which is a direct reflection of the quality of school sports work, while the perception of sports environment, physical activity behavior, and self-efficacy in sports learning are closely related to their sports gains, which directly affects their effectiveness and interest in sports learning.
Objective: To investigate the effects of perceived sports environment on Chinese college students' sport gains, and to verify the mediating roles of physical activity behavior and self-efficacy in sport learning.
Methods: A survey of 2,207 Chinese university students was conducted using the sport environment perception scale, sport gain scale, physical activity behavior scale, and sport learning self-efficacy scale.
Background: Self-management support is widely considered a critical aspect of nursing. Still, many studies indicate that nurses frequently experience difficulties in daily practice.
Objective: To gain a deeper understanding of the factors perceived by nurses to impede or promote their support of patients' self-management within the dynamic environment of the in-patient hospital setting.
The use of pesticides for diseases and insect pest control has become a key component in smallholder vegetable production. This study therefore quantified the concentration of pesticide active ingredient per unit production land (kg a.i/ha), and drivers of increased pesticide use in smallholder vegetable production systems in Tanzania.
Background: Little is known about the association between air pollution and self-perceived health (including both health-related quality of life [HRQoL] and self-rated health [SRH]). The aim of this study was therefore to explore whether long-term air pollution exposure is associated with worse self-perceived health, as measured by different tools.
Methods: We used a land-use regression model to determine the annual average levels of particulate matter with a diameter <10 μm (PM), coarse particles (PM), fine particles (PM), fine particle absorbances (PM), particle number concentration (PNC), ozone (O), nitrogen dioxide (NO), and nitrogen oxide (NO) for geocoded residential addresses (2014-2015).
