By David T. McNaughton, Kristine Ensrud, Lisa Langsetmo and 13 others.
Abstract
Background
The association between back pain and frailty is uncertain. This study examined the association between back pain in older men and prospective frailty status an average of 7 years later.
Methods
Prospective cohort study using data from the Osteoporotic Fractures in Men Study. Eligible participants were men who, at study Visit 3 (Year 7), completed a back pain assessment (presence, frequency, severity, activity limitation) and a phenotypic frailty assessment (robust, pre-frail, frail). Among men classified as either robust or pre-frail, phenotypic frailty was again assessed at Visit 4 (Year 14), with deaths between Visits 3 and 4 considered a separate terminal outcome category. The association of Visit 3 back pain with frailty phenotype relative to a robust (and pre-frail) status at Visit 4 was analyzed using multivariable-adjusted multinominal logistic regression models.
