Reaction: implementing green axes in Barcelona could reduce antidepressant use and visits to mental health professionals

A health impact study led by the Barcelona Institute for Global Health (ISGlobal) concludes that implementing green axes throughout the city of Barcelona would lead to a "considerable reduction" in the mental health problems suffered by the adult population and in the direct and indirect costs associated with them. The study is published in the journal Environment International.

This study conducts a mental health impact assessment of the Eixos Verds programme, which aims to increase green spaces in Barcelona. Potential mental health benefits of the programme are found.  

The research group has extensive experience in the use of health impact assessment methodology, and there are no methodological problems beyond those expected.  

Some of these limitations are that it is difficult to measure whether these health effects will benefit the whole population equally, or whether the Eixos Verds programme will have consequences on the housing market in the areas of application.

"I have been collaborating for the past four years on a research project with Mark Nieuwenhuijsen, one of the co-authors of the paper".
