Large walking and wellbeing behaviour benefits of co-designed sustainable park improvements: A natural experimental study in a UK deprived urban area.

There is little robust evidence of how sustainable park interventions impact on physical activity and other behaviours important for wellbeing. This controlled natural experimental study aimed to examine the effects of co-designing a sustainable park intervention, in a deprived UK urban area, on walking and other wellbeing behaviours. Behaviour observations were conducted at two intervention sites and two matched comparison sites (n = 4,783).
