The study effect of built environment characteristics on physical activity and walking Citizens in Mashhad

The research of the relationship between the characteristics of the urban Built environment with physical activity and citizen mobility has attracted the interest of many researchers as it reveals the increasing effects of physical activity and mobility on the health of individuals and especially urban dwellers. Accordingly, the objective of this research is to study the effect of urban built environment on physical activity and walking of citizens in Mashhad. Research is a developmental-applied research. Methodologically, and in the category of macro, it falls into descriptive researches and in subdivisions of case studies, surveys, and correlations. Land use mix, population density and Walkability indices were used to assess the Built environment. Statistical Society is up to 25 old of Mashhad citizens and sample size is 1022 in 16 neighborhoods. The results showed that nearly half of the people practically did not participate in any physical activity and about 41% had less than half an hour of daily walking. In the studied areas, there was no significant relationship between physical activity (Sharkey Physical Activity Index) and daily walking with land use mix. Also, there was no significant relationship between population density and physical activity intensity (Sharkey Physical Activity Index), but there was a significant and inverse relationship between population density and daily walking and finally, there was no significant relationship between walkability and daily walking and physical activity based on the Sharkey index. Since the results of this study are different from those of Lotfi (2012) and Nikpour et al., (2017), further experimental studies are necessary.
