To describe disability in individuals with hip arthroplasty and its evolution over 2 years compared with that in the general population, and to compare the degree of disability between subjects with recent and older hip arthroplasty.
We selected a national representative sample of 16,945 subjects from the 1999 French population census. This sample, interviewed in 1999 and 2001 about their level of disability, included 527 subjects with hip arthroplasty (i.e., representing 424,000 individuals in the French noninstitutionalized population): 145 who underwent the procedure between 1999 and 2001 (recent hip arthroplasty) and 382 with an older hip arthroplasty.
Subjects with hip arthroplasty reported more difficulty in bending forward (odds ratio [OR] 4.5, 95% confidence interval [95% CI] 3.1–6.6), climbing stairs (OR 2.2, 95% CI 1.5–3.1), walking >300 meters (OR 1.6, 95% CI 1.03–2.6), dressing (OR 2.9, 95% CI 2.1–4.2), and getting in and out of a chair (OR 2.5, 95% CI 1.7–3.6) than the general population. However, the evolution in disability was similar to that of the general population. Compared with subjects with older hip arthroplasty, those with recent hip arthroplasty reported more difficulty walking >300 meters (OR 2.7, 95% CI 1.3–5.6), washing (OR 2.9, 95% CI 1.6–5.4), dressing (OR 2.2, 95% CI 1.2–4.2), and getting in and out of a chair (OR 2.1, 95% CI 1.1–3.9).
This study describes the potential future disability in the more elderly population, with implications for health-related planning.
