Health-related quality of life in older adults with bilateral knee pain and back pain: data from the Osteoarthritis Initiative

This study’s objective was to examine the association of self-reported bilateral knee pain (KP) and back pain (BP) with health-related quality of life (HRQoL) among older adults. In this cross-sectional study, data for 1252 older adults (≥65 years) were included from the Osteoarthritis Initiative project. Self-reported bilateral KP and BP were used to classify participants into four groups: (1) neither bilateral KP nor BP; (2) no bilateral KP with BP; (3) bilateral KP without BP; and (4) both bilateral KP and BP. Health-related quality of life was measured using the health survey short form (SF)-12. We used multiple linear regression analyses to examine the associations of bilateral KP and/or BP with the HRQoL. After controlling for covariates, bilateral KP and BP were associated with poorer HRQoL [physical composite scale (PCS): estimated average (β) = −13.1, SE = 1.15, p < 0.0001; mental composite scale: β = −2.71, SE = 1.09, p = 0.013, respectively] compared with the group with neither bilateral KP nor BP. In conclusion, older adults with coexisting bilateral KP and BP had significantly poorer physical and mental HRQoL when compared to peers without these conditions.
