Community built environment factors and mobility around senior wellness centers: the concept of "safe senior zones".

The authors investigated built environment (BE) factors in urban neighborhoods in DeKalb County, Georgia. Each volunteering, consenting senior was placed into one of two groups: walking tours outside, then discussions (n=37); and focus group discussions indoors about photographs of BE conditions potentially influencing mobility (n=43). The authors sought to identify BE factors-both real and perceived by participating seniors-related to their ability to walk around senior wellness centers in a healthy and safe manner.
