Empirical evidence of the association between the presence of musculoskeletal pain and physical disability in community-dwelling senior citizens.

The proportion of people 65 years of age and older who report musculoskeletal pain and physical disability is high. The main objective of this study was to determine whether physical disability was associated with the presence of musculoskeletal pain in a sample of senior citizens. Self-administered questionnaires were sent to a sample of 1306 community-dwelling senior citizens in London, Ontario, Canada between August and October 1995. The questionnaire included questions about pain, difficulty performing activities, depressive symptoms, chronic conditions, and demographic information. A total of 887 seniors completed the questionnaire (70.7% response rate, aged 65-94, 41.2% men, 58.8% women). Logistic regression analysis, without controlling for potential confounding variables, revealed that those who reported having musculoskeletal pain were seven times more likely to have some difficulty performing three or more activities listed in the questionnaire (OR = 6.91 95% CI 4.92-9.69). When significant confounding variables were controlled in the analysis, seniors who reported musculoskeletal pain were still three times more likely to have some difficulty with three or more activities (OR = 2.93, 95% CI 1.96-4.38). Although no causal relationship can be inferred, thorough pain assessment and pain management may be important in the maintenance of independent living for adults 65 years of age or older.
