	abstract = {{OBJECTIVE}: To examine the association between body mass index ({BMI}) and osteoarthritis ({OA}) leading to total hip ({THR}) or knee ({TKR}) joint replacement.
{METHODS}: Case-control study design. All patients still living in Iceland who had had a {THR} or {TKR} resulting from {OA} before the end of 2002 were invited to participate. First-degree relatives of participating patients served as controls. A total of 1473 patients (872 women) and 1103 controls (599 women), all born between 1910 and 1939 and who had answered a questionnaire including questions about height and weight, were analysed. A randomly selected sample, representative of the Icelandic population, was used as a secondary control group.
{RESULTS}: The {OR}, adjusted for age, occupation and presence of hand {OA}, for having a {THR} was 1.1 (95\% {CI} 0.9 to 1.5) for overweight men and 1.7 (95\% {CI} 1.0 to 2.9) for obese men. The {OR} for having a {TKR} was 1.7 (95\% {CI} 1.1 to 2.6) for overweight men and 5.3 (95\% {CI} 2.8 to 10.1) for obese men. The {OR} for having a {THR} was 1.0 (95\% {CI} 0.8 to 1.3) for overweight women and 1.0 (95\% {CI} 0.6 to 1.5) for obese women. The {OR} for having a {TKR} was 1.6 (95\% {CI} 1.1 to 2.2) for overweight women and 4.0 (95\% {CI} 2.6 to 6.1) for obese women.
{CONCLUSION}: This study supports a positive association between high {BMI} and {TKR} in both sexes, but for {THR} the association with {BMI} seems to be weaker, and possibly negligible for women.},
