Daily Movement (Wrist Accelerometer, MIMS)

Higher values go with lower risk of death. In NHANES 1999–2018 with linked mortality to 2019, each standard deviation above average goes with 45% lower risk of death. We found the same pattern in NHANES

Risk of death relative to each curve's own reference value, so the two curves need not cross 1 at the same point. The dotted vertical line marks the NHANES median.

Risk of death per SD (NHANES)0.55×95% CI 0.50–0.60 · 8,082 adults, 822 deaths

Published risk of death0.55×per SD (95% CI 0.50–0.60) · NHANES 2011-2014 PAM participants aged 20-84 with >= 3 valid wear days, NCHS 2019 Linked Mortality Files (follow-up to 31 Dec 2019, median 6.8 y)

Daily Movement (Wrist Accelerometer, MIMS) by age and sex

Each bar runs from the 5th to the 95th percentile, the darker part from the 25th to the 75th, and the tick is the median. Not a reference range or a target.

The percentiles as a table

Each row is one sex and age band: the values below which 5%, 25%, 50%, 75% and 95% of people fall (MIMS/day), from the survey named in the row. Not a reference range or a target.
