Snacktivity WP4

A multi-centre, open-label, two-arm, parallel group, individually randomised trial, with an internal pilot and economic evaluation, to test the superiority of Snacktivity compared with usual care

Updated 22 July 2024

Participants will be randomised to receive standard advice about physical activity or encouraged to achieve their physical activity through Snacktivity (small changes). Snacktivity participants will receive a physical activity tracker (Fitbit) to help monitor their Snacktivity and overall physical activity and given access to a mobile phone App called the SnackApp that prompts and supports people to participate in Snacktivity. We will measure all participants’ physical activity at baseline, 3 and 12 months after they start the study to assess whether the Snacktivity intervention helps people to become more physically active. We will also measure other variables such as how participants feel about Snacktivity/activity and their mental health. We will assess whether the Snacktivity intervention is cost effective to the NHS.
