title: [Evaluation of perceptions of physical activity related built environment among urban adults with different characteristics in Hangzhou].
abstract: OBJECTIVE
  To understand the perceptions of physical activity-related built environment among urban adults in Hangzhou.
  
  
  METHODS
  A face-to-face interview was conducted among the urban residents aged 25-59 years selected through multistage stratified random sampling in Hangzhou in 2012. The Neighborhood Environment Walkability Scale-Abbreviated (NEWS-A) was used to assess the perception of built environment among residents, including residential building density, the diversities of stores, facilities and others, the accessibility to public service, the street connectivity, walking/cycling facilities, aesthetics, traffic safety, and public security. The multilevel logistic regression model was used to assess the demographic characteristics, BMI and other factors' influence on people's perceptions.
  
  
  RESULTS
  Among 1 362 local residents surveyed, no sex, martial status and occupation specific significant differences in the perception of built environment were found. After adjusting other factors, the age group 45-59 years was positively related to the score of street connectivity (OR=2.02, 95% CI: 1.30-3.15). The educational level of college or higher was positively associated with the score of residential building density (OR=1.97, 95% CI: 1.29-3.00) but negatively associated with the score of facility variety (OR=0.65, 95% CI: 0.43-0.97). Overweight or obesity was negatively related to the scores of walking/cycling ways (OR=0.67, 95%CI: 0.48-0.95) and public security (OR=0.75, 95% CI: 0.57-0.99). Compared with the class I residential area, the people in class III residential area had lower perception scores on facility diversity (OR=0.11, 95% CI: 0.04-0.30), accessibility to public service (OR=0.33, 95% CI: 0.11-0.95), street connectivity (OR=0.30, 95% CI: 0.11-0.86) and traffic safety (OR=0.39, 95% CI: 0.17-0.91).
  
  
  CONCLUSIONS
  The perceptions of physical activity-related built environment was associated with age, educational level, BMI and residential area. The personal characteristics should be considered while performing environment intervention on physical activity.
