To assess the prevalence of knee pain, disability and health status in the community, and to examine the association of pain with psychological distress.
A postal survey was sent to 4057 men and women aged 40-79 yr in Nottingham. Health status was assessed using the SF-36 instrument, with the specific dimensions of physical function and mental health used to measure disability and psychological distress.
The overall response rate was 81.9%. The prevalence of knee pain was 28.7%, rising with age. Disability was more common in those with knee pain compared to those without pain (P < 0.001). Subjects with knee pain had lower scores for all dimensions of health. When adjusted for potential confounders, low mental health scores associated with increased odds for pain and disability (2.1, 95% CI 1.7-2.6; and 4.7, 95% CI 3.7-6.1).
Knee pain is common in this population and is associated with poor perceived health and significant disability. Psychological distress strongly associates with both pain and disability.
评估社区中膝关节疼痛、功能障碍及健康状况的患病率，并研究疼痛与心理困扰之间的关联。
对诺丁汉4057名年龄在40 - 79岁的男性和女性进行邮寄调查。使用SF - 36量表评估健康状况，采用身体功能和心理健康的特定维度来衡量功能障碍和心理困扰。
总体回复率为81.9%。膝关节疼痛的患病率为28.7%，且随年龄增长而上升。与无疼痛者相比，膝关节疼痛者功能障碍更为常见（P < 0.001）。膝关节疼痛的受试者在所有健康维度上得分较低。在对潜在混杂因素进行校正后，心理健康得分低与疼痛和功能障碍的几率增加相关（分别为2.1，95%可信区间1.7 - 2.6；以及4.7，95%可信区间3.7 - 6.1）。
在该人群中膝关节疼痛很常见，且与健康状况不佳和严重功能障碍相关。心理困扰与疼痛和功能障碍均密切相关。
