New paper in BMC Public Health! We looked at how the world's favorite stimulant, caffeine, associated with objective sleep and PA among older adults in the 2011-14 NHANES. Caffeine consumers were >10% more active overall and were highly active for >24mins per day vs non-consumers. Link below.

New paper out in npj Aging! We found that ML models using wearable features (sleep, PA, circadian) + age + education predicted poor cognitive test performance reasonably well, but only for tests assessing certain cognitive domains (AUCs .71 to .84). Associations also varied by outcome. Link below!

I enjoyed my first ever conference at #GSA2024 ! I presented a poster on accelerometer-derived PA, sleep efficiency, and their associations with mortality among older adults in the UK Biobank. Full paper with additional findings (hopefully) coming soon.
