The objective is to determine the prevalence of self-reported physician-diagnosed osteoarthritis (OA) and musculoskeletal symptoms (pain, stiffness or discomfort) in specific joints among adults in British Columbia (BC), Canada. We carried out a cross-sectional mixed-mode survey in a random population sample of persons 18 years of age and older. Estimates were weighted to reflect the age and sex distribution of the population of BC. We obtained responses from 2,233 individuals. Overall, 18.4% (95% CI 16.8-20.1) of the adult population reported OA. Of those, more than 40% had OA in multiple sites. Prevalence ranged from 8.8% (95% CI 7.6-10.1) in the knee to 2.7% (2.1-3.5) in the foot. One-year prevalence of symptoms ranged from 49.1% (47.0-51.2) in the lower back to 23.3% (21.5-25.1) in the hip. Females reported more symptoms and OA than males in all joints. The most common site of self-reported physician-diagnosed OA in BC is the knee, but OA in the hands, hips, and feet is also common. Having OA in one joint is a strong predictor of OA in other joints.
目的是确定加拿大不列颠哥伦比亚省（BC）成年人中特定关节的自我报告的医生诊断骨关节炎（OA）和肌肉骨骼症状（疼痛、僵硬或不适）的患病率。我们在 BC 随机人口样本中进行了横断面混合模式调查。估计数经过加权，以反映 BC 人口的年龄和性别分布。我们收到了 2233 个人的回复。总体而言，18.4%（95%CI 16.8-20.1）的成年人口报告了 OA。其中，超过 40%的人在多个部位患有 OA。患病率从膝关节的 8.8%（95%CI 7.6-10.1）到足部的 2.7%（2.1-3.5）不等。症状的一年患病率从下背部的 49.1%（47.0-51.2）到臀部的 23.3%（21.5-25.1）不等。在所有关节中，女性报告的症状和 OA 比男性多。在 BC，自我报告的医生诊断 OA 最常见的部位是膝盖，但手部、臀部和脚部的 OA 也很常见。一个关节的 OA 是其他关节 OA 的强烈预测因素。
