Rees-Punia E, et al. - Given perceived safety from crime and objectively-measured crime rates may be associated with physical inactivity, researchers analyzed data from relevant studies in order to estimate the odds of accumulating high levels of physical activity (PA) when the perception of safety from crime is high and when objectively-measured crime is high. A 27% greater odds of achieving higher levels of physical activity was reported for those who felt safe from crime. A 28% reduced odds of achieving higher levels of physical activity was reported for those living in areas with higher objectively-measured crime. The mean link between perceived safety and PA was significant although the limited number of impacts suitable for aggregation were reported. Possibly, perceived lack of safety from crime constrains PA behaviors.
