What it is
Daily steps as counted by a phone or a watch. This is total volume, not how fast you walk. Ding’s review used device-measured steps; a phone or watch reading can differ from those study measurements.
How the score uses it
Technical notes
The curve uses Ding 2025’s 14-study all-cause dose-response (not the 57-study review count): 7,000 steps/day HR 0.53 versus a 2,000-step reference, with an inflection around 5,000–7,000. Main source: Ding. Supporting: Paluch 2022 (age-stratified individual-participant data, plateau 6–8k at ≥60 y, 8–10k under 60) / Banach 2023 (15% lower all-cause mortality per 1,000 extra steps as a summary increment; nonlinear spline dose-response) / Inoue 2023 (≥8,000 steps 1–2 days/week is an NHANES risk difference, not Ding’s daily-average HR). Interiors of the calculator curve between those published anchors are constructed.
How to improve it
- Add a 10–15 minute walk after meals
- Take walking phone calls
- Park further away and take stairs
- Aim for a realistic weekly step goal, not perfection
