Green space and changes in self-rated health among people with chronic illness.

This prospective study analyses change in self-rated health of chronically ill people in relation to green space in their living environment at baseline. Data on 1112 people in the Netherlands with one or more medically diagnosed chronic disease(s) were used. The percentage of green space was calculated for postal code area. Multilevel linear regression analysis was conducted. We found no relationship between green space and change in health; however, an unexpected relationship between social capital at baseline and health change was discovered. (aut.ref.)
