Arthritis, of which osteoarthritis (OA) is the most common type, is the most frequent cause of disability among adults in the United States. The authors reviewed the epidemiologic literature to identify studies that describe the population-based burden of OA-that is, the burden in all adults in the community. They found that 27 million adults-more than 10% of the U.S. adult population-had clinical OA in 2005, and in 2009 OA was the fourth most common cause of hospitalization. OA is the leading indication for joint replacement surgery; 905,000 knee and hip replacements were performed in 2009 at a cost of $42.3 billion. Obesity is a strong risk factor for OA of the knee and hip. Nurses can improve the quality of life of people with OA by raising awareness among their patients and peers of the substantial OA burden and the strategies, such as physical activity, that can reduce it.
关节炎是美国成年人最常见的致残原因，其中骨关节炎（OA）最为常见。作者查阅了流行病学文献，以确定描述 OA 人群负担的研究——即社区内所有成年人的负担。他们发现，2005 年有 2700 万成年人——超过美国成年人口的 10%——患有临床 OA，2009 年 OA 是第四大常见住院原因。OA 是关节置换手术的主要指征；2009 年进行了 90.5 万例膝关节和髋关节置换手术，费用为 423 亿美元。肥胖是膝关节和髋关节 OA 的一个强烈危险因素。护士可以通过提高患者和同行对大量 OA 负担以及可以减轻 OA 负担的策略（如体育活动）的认识，来改善 OA 患者的生活质量。
