Over 40% of NZ adults are insufficiently physically active. In this blog we summarise our recently published modelling work that suggests that the prescription of smartphone apps for physical activity promotion in primary care could benefit health and save millions in health sector costs for NZ. Nevertheless, this type of intervention should ideally occur in conjunction with societal-wide shifts that support more walking and cycling, as these are likely to generate much larger health gains and cost-savings.
