111 5.4 Discussion 5.4.1 Urban Green Space and  Health Outcomes in  Relation to  Socio-demographic and  Socio-economic Confounders This study presents the results of a systematic quantitative review that focuses on the association between green spaces and health outcomes with a particular focus on potential socio-economic and socio-demographic confounding factors.
