A team of
Canadian researchers has established that four distinct physical activity
profiles are detectable using activity monitoring among adults with arthritis.
In their study
just published online in Arthritis Care & Research, Lynne M. Feehan,
Ph.D., from the University of British Columbia in Vancouver, Canada, and
colleagues assessed 24-hour activity-sleep profiles in 172 adults with
arthritis (rheumatoid arthritis, systemic lupus erythematosus, or knee
researchers identified clusters of high sitters (6.9 hours sleep, 1.6 hours
rest, 13.2 hours non-ambulatory, 1.6 hours intermittent, and 0.3 hours
purposeful walking); low sleepers (6.5 hours sleep, 1.2 hours rest, 12.2 hours non-ambulatory,
3.3 hours intermittent, and 0.6 hours purposeful walking); high sleepers (8.4
hours sleep, 1.9 hours rest, 10.4 hours non-ambulatory, 2.5 hours intermittent,
and 0.3 hours purposeful walking); and those with balanced activity (7.4 hours
sleep, 1.5 hours rest, 9.4 hours non-ambulatory, 4.4 hours intermittent, and
0.8 hours purposeful walking).
activity was associated with younger age (odds ratio, 0.95), weaker
occupational sitting habit (odds ratio, 0.55), and stronger walking-outside
habit (odds ratio, 1.43) versus high sitters.
tailoring interventions based on 24-hour activity-sleep profiles may be indicated,
particularly in adults with stronger habitual sitting or weaker walking behaviours,”
