There’s more evidence that green = health. No, not tea, but more green space.
 
More specifically, access to green space lessens health disparities between the wealthy and the not-so-rich in the community.
 
Green spaces reduce the health gap between rich and poor, according to a study published in the Lancet, Effect of exposure to natural environment on health inequities: an observational population study by Dr. Richard Mitchell and Dr. Frank Popham, Scottish researchers in public health and geography, respectively.
 
Mitchell and Popham found that health disparities between the rich and the poor can be halved with citizens’ access to green spaces. They examined data on the under-retirement age English population and found the greatest health impact on peoples’ access to green space was in circulatory diseases.
 

Access to green space, the researchers say, brings a natural environment to people that directly influences their health behaviors. They define green spaces as “open, undeveloped land with natural vegetation,” including such geographic areas as parks, playing fields, forests, and woodlands.
 

The methodology: in geographic terms, the researchers looked at the amount of green space per lower level super output area (LSOA) – a small geographical area used by the UK Office for National Statistics. Individual death records of citizens living in various LSOAs were analyzed for deaths between 2001 and 2005 looking at
cause of death, age at death and gender.
 

Their conclusion: health disparities in circulatory disease mortality for people with lower incomes appears to be lower in people who live in regions of high green space compared to people living in low green space areas.
 

The authors identified several weaknesses in the study and so did not conclusively say that exposure to green space is responsible for the observed reduction in health inequalities.

Health Populi’s Hot Points: An article in the UK’s Independent newspaper put this important finding succinctly: Life near a city park can be as healthy as out in the country.

There’s a new walkability index that’s a useful test to take: find it at Walkscore. By typing in your address, you will yield a score that runs from “worst” to “best.” Suffice it to say if you live in Manhattan or Boston or Williamsburg, VA, you’re very walkable. If you’re in the suburbs and need a car to go everywhere, go find some green space, and fast!

While Mitchell and Popham won’t write with 100% certainty that access to green space leads to better health outcomes…go take a walk, anyway, wherever you are. Like chicken soup for a cold and a positive attitude and social network…it couldn’t hurt!
