Green space is associated with improved health, but researchers know little about mechanisms underlying the association. A study, published recently in Environment International and led by CREAL, an ISGlobal allied center, aimed to assess the association between greenness exposure and subjective general health and to evaluate mental health status, social support, and physical activity as potential mediators of this association. This cross-sectional study used a population-based sample of 3461 adults residing in Barcelona, Spain. The researchers characterized outcome and mediators using the Health Survey of Barcelona (2011), elaborated by the Public Health Agency of Barcelona (ASPB).
Researchers found that residential surrounding greenness and subjective residential proximity to green spaces were associated with better subjective general health. “We found indications for mediation of these associations by mental health status, perceived social support, and to less extent, by physical activity”, explained Payam Dadvand, researcher at CREAL and first author of the study.
