Large walking and wellbeing behaviour benefits of co-designed sustainable park improvements: A natural experimental study in a UK deprived urban area
Abstract
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). Walking observations (primary outcome), wellbeing behaviours (vigorous, sedentary, social and take notice activities) and demographic characteristics were assessed at pre-intervention, and post-intervention (3 and 15 months). Outcomes were compared between intervention and comparison groups, controlling for pre-intervention using multilevel negative binomial regression models. Additional behaviour observations were conducted in two unchanged nearby sites to assess changes in general local activity. Intercept surveys (n = 623) assessed change in self-reported outdoor space usage at intervention and control areas.Post-intervention, walking increased 203 % at 3 months (IRR 2·03, 95 % CI 1·01-4·09) and 351 % at 15 months (IRR 3·51, 95 % CI 2·07-5·93), for intervention sites relative to comparison sites. Large increases for other wellbeing behaviours were also observed. The proportion of non-white persons increased substantially post-intervention, compared to comparison sites. Nearby unchanged sites showed little evidence of general increased activity. Self-reported outdoor usage increased more in the intervention sites (p=<0·001).Sustainable solutions can yield large increases in walking and wellbeing in deprived areas, especially where interventions are co-designed with residents. More collaborative and robust natural experimental studies like this are needed to better inform decision-makers how to maximise health and wellbeing outcomes from sustainable interventions.
