Associations between perceived and observational physical environmental factors and the use of walking paths: A cross-sectional study

Abstract

Background: How to promote physical activity is an important public health problem that is attracting increasing attention. Although the application of environmental approaches is believed to promote resident walking, there remains insufficient evidence of the effectiveness of these interventions. Methods. This study employed direct observation and questionnaires. Observations were performed on each Tuesday, Thursday, Saturday, and Sunday from April 13th to May 16th. Fourteen trained observers observed six community walking paths, and an additional walking path in a park. The trained observers filled out 2388 observation forms in the field, including 228 forms rating the permanent environment, and 1080 forms assessing the current environment and counting the number of walkers. A total of 1800 questionnaireswere administered to community residents. Results: The results of both observation and questionnaires showed good association regarding the characteristics of walking path users (for observation, female = 54.4%; for questionnaire interviews, female, OR = 1.441), and the environmental features associated with walking path utilization (for observation, positive associations were observed between the utilization index and observational environmental variables; for questionnaire interviews, roads and aesthetics were important, OR = 1.044). There were positive associations between path use and time, a preference for brisk walking, and the observed current and permanent environmental variables. Female participants were more likely to use walking paths than males (OR = 1.441, 95% confidence interval [CI] 1.126-1.846). BMI and traffic hazard safety were significantly negatively associated with walking path use (OR = 0.948, 95% CI 0.915-0.981, and OR = 0.933, 95% CI 0.887-0.981, respectively). Roads, aesthetics, and knowledge of physical activity were significantly positively correlated with use of walking paths (OR = 1.044, 95% CI 1.017-1.072, and OR = 1.175, 95% CI 1.043-1.323). Participants that resided further than 1 km from the park were less likely to use walking paths (OR = 0.703, 95% CI 0.530-0.933). Gender-specific associations were also found. Conclusions: Both perceived and objective environmental factors were associated with walking path use. Data suggested that the permanent and current conditions of the paths might influence walking path utilization, and that gender-specific promotion strategies should be considered. © 2014 Jia and Fu; licensee BioMed Central Ltd.
