Severity was classified by means of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores (range=0\u2013100): &amp;lt;7=asymptomatic, 7\u201338=mild-moderate, and \u226539=severe. Health-related quality of life was evaluated by means of the Assessment of Quality of Life (AQoL) instrument (range=\u22120.04 to 1.00; scored worst-best). Self-reported data on work status and health service utilization were collected, with health care costs estimated with the use of government data.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Data were available for 1,157 participants, with 237 (20%) reporting hip or knee joint disease. Of these, 16% (n=37) were classified as asymptomatic, 51% (n=120) as mild-moderate, and 27% (n=64) as severe. The severe group reported very low HRQoL (adjusted mean AQoL=0.43, 95% confidence interval [95% CI]=0.38\u20130.47) compared with the mild-moderate group (adjusted mean AQoL=0.72, 95% CI=0.69\u20130.75) and the asymptomatic group (adjusted mean AQoL=0.80, 95% CI=0.74\u20130.86). Compared with the asymptomatic group, the severe group was &amp;gt;3 times less likely to undertake paid work (adjusted odds ratio=0.28, 95% CI=0.09\u20130.88) and &amp;gt;4 times less likely to undertake unpaid work (adjusted odds ratio=0.24, 95% CI=0.10\u20130.62).
