Relationship of cognition and structured grocery shopping in older adults with and without mild cognitive impairment
Keith R. Cole, Katherine A. Gifford, Leslie Davidson. Alzheimer s & Dementia, 2025-12-01
Topic: Risk, prevention and care in population studies
Age was similar between groups (p = 0.07). MCI had slower accelerations per minute and gyroscope degrees per minute at the head (p <0.001, d=0.51; p <0.001, d=0.69) and lumbar spine (p = 0.003, d=0.0.60; p <0.001, d=0.66) compared to CU. Regression models using the Flanker test explained the greatest amount of variance, explaining 26% and 37% at the head (p's <0.001) and 21% and 22% and at the lumbar spine (p <0.001) of acceleration and degrees of movement, respectively. Objective measurements of movement using wearable technology during real-world activities, such as grocery shopping, may be a digital biomarker of cognitive and physical function. As cognition declines, in particular executive functioning, the overall accelerations and speed of rotational movements particularly at the head may reflect more significant changes in cognition. Future studies are needed in community grocery stores to assess free-living IADLs to determine if such activities can be used as a digital biomarker of cognitive, motoric, and functional decline.

Key findings
- Age was similar between groups (p = 0.07).
- MCI had slower accelerations per minute and gyroscope degrees per minute at the head (p <0.001, d=0.51; p <0.001, d=0.69) and lumbar spine (p = 0.003, d=0.0.60; p <0.001, d=0.66) compared to CU.
- Regression models using the Flanker test explained the greatest amount of variance, explaining 26% and 37% at the head (p's <0.001) and 21% and 22% and at the lumbar spine (p <0.001) of acceleration and degrees of movement, respectively.
- Objective measurements of movement using wearable technology during real-world activities, such as grocery shopping, may be a digital biomarker of cognitive and physical function.
- As cognition declines, in particular executive functioning, the overall accelerations and speed of rotational movements particularly at the head may reflect more significant changes in cognition.
Why it matters
This study found that older adults with mild cognitive impairment moved more slowly during a grocery shopping task than those without it, and that executive function explained much of this difference. It suggests wearable movement measures during real-world activities might serve as a marker, but it does not test a treatment or cure for Alzheimer's disease.
