Activity-Limiting Back Pain Linked to Later Frailty in Older Men

A prospective analysis from the Osteoporotic Fractures in Men (MrOS) Study examined whether back pain was associated with subsequent frailty among community-dwelling older men. Of 5,994 enrolled participants, 2,554 classified as robust or pre-frail at Visit 3 were included. Researchers assessed back pain presence, frequency, severity and activity limitation, then reassessed phenotypic frailty approximately seven years later. Deaths during follow-up were treated as a separate terminal outcome.

After adjustment for age, clinic site, race and education, several back pain measures were associated with higher odds of later frailty compared with either robust or pre-frail status. With additional adjustment, including initial frailty status, only activity-limiting back pain remained significantly associated with frailty versus pre-frailty (odds ratio 1.40, reported interval 1.03–1.90). No back pain phenotype remained associated with higher odds of frailty versus robust status.

Published in the Journal of the American Geriatrics Society, these findings suggest that activity limitation accompanying back pain may be relevant to frailty assessment in older men. However, the attenuation after adjustment limits interpretation, and this observational analysis does not establish that treating back pain prevents frailty. Replication and investigation of underlying mechanisms are needed; full-text details were unavailable for this update.
