Adults who live more than 0.8 km (or about a half a mile) from urban green space appear to be less likely to develop type 2 diabetes, according to research in the 2018 BMJ Open (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5781018/). The researchers were actually interested in whether proximity to green space in inner city areas had an impact on BMI (body mass index) or type 2 diabetes risk, or both. The research was done in Germany, so perhaps it is only relevant to Germans. Nonetheless, they found that while green space location doesn’t appear to have a relationship with BMI, they did find that adults who are closer to green space are less likely to have type 2 diabetes. Type 2 diabetes is correlated with excess weight — and other factors such as sedentary lifestyles. This research (and other similar research) suggests that if green space is close enough, people will go to it and enjoy it. A 2011 study in the Journal of Physical Activity and Health seems to confirm that people who are closer to green space are also more likely to be physically active and closer to normal weight. I personally think that there may be other factors involved. We know that green space reduces stress and depression — and it is also possible that these feed into people’s diabetes risk as well.
This is important news for families as well as city planners – it’s a good idea to get out into green space together if you can. And if you have a chance to advocate for more green spaces in your neighborhood, do so.
