A new piece of CRESH research has been published online in the journal Public Health this week. The paper “The role of physical activity in the relationship between urban green space and health” can be downloaded here. We looked at the health of over 8000 individuals who were interviewed for the New Zealand Health Survey in 2006 and 2007 and asked whether they were likely to be healthier if they lived in greener neighbourhoods. We found that residents of greener neighbourhoods did indeed have better cardiovascular and mental health, independently of their individual risk factors (e.g., sex, age, socioeconomic status). Green space might benefit health because it provides greater opportunities for physical activity, and we were able to test this hypothesis because the New Zealand Health Survey included information about how physically active each individual respondent typically was. We found that although physical activity was higher in greener neighbourhoods it did not fully explain the green space and health relationship. Therefore, other pathways between green space and health (e.g., social contacts, attention restoration) are likely to be equally/more important.
