OBJECTIVE: Determination of the prevalence of @entity717 and its association with signs and symptoms of the hips and knees in a Dutch general population aged 55 years and over. DESIGN: Cross-sectional population-based study. SETTING: Rotterdam-Ommoord, the Netherlands. METHOD: During home interviews of 1,901 @entity1 and 3,132 @entity1 aged 55 years and over living in the Ommoord district of @entity717 was assessed using the Health Assessment Questionnaire (HAQ). Morning @entity2693 and @entity158 during the past month were assessed. At the research centre weightbearing radiographs of the hips and knees were taken. @entity571 was defined as Kellgren score 2 or more. A complete physical examination of the hips and knees was performed. RESULTS: The prevalence of @entity717 was 21.9% for independently living @entity1 and 36.0% for independently living @entity1 . In homes for the elderly these figures were 84.0% en 96.5%, respectively. There were significantly elevated age-adjusted odds ratios for @entity717 for @entity1 , @entity1 in homes for the elderly, independently living @entity1 with only primary education, independently living @entity1 with a below-median net annual income and widowed @entity1 in homes for the elderly. Taking the associations between the independent variables into account only morning @entity2693 , @entity158 and restricted flexion of the hips and knees were independently associated with @entity717 in @entity1 . In @entity1 radiological @entity571 of the hips and knees, restricted endorotation of the hip, instability and @entity85 of the knees were also associated with disability. CONCLUSION: The prevalence of @entity717 in @entity1 aged 55 years and over in the general population was high and associated with female sex, low education, low income and living in a home for the elderly. Of the signs and symptoms of the hips and knees only @entity158 , morning @entity2693 and restricted flexion of the hip were independently associated with @entity717 . @entity571 of the hip and knee did not contribute much to the explanation of @entity717 .
