Data from the 1988 Medical Device Implant Supplement to the National Health Interview Survey are used to summarize information about the prevalence of artificial hips among adults in the United States. The 1988 National Health Interview Survey was a cross-sectional survey of the civilian noninstitutionalized United States population, and included 122,310 persons in 47,485 households in a multistage probability sample. The supplement supplied the first population-based estimates of prevalence and morbidity of selected medical devices. Projected to the United States population, the survey results indicate that an estimated 674,000 adults were using 811,000 hip implants. Hip implant recipients were significantly more likely to be older, to be white, and to have lower educational, income, and activity levels than the general population of adults. After age-stratification, however, only differences in activity limitation and race remained. Current economic outlays for hip replacement surgery are substantial. With the aging population, use of health services by patients with artificial hips will probably increase unless measures to reduce the need for replacement surgery are instituted. These measures include reducing injuries and improving biomaterials. Further investigation is needed to examine the activity limitation and racial difference in prevalence found in this study.
1988年全国健康访谈调查医疗设备植入补充调查的数据用于总结美国成年人中人工髋关节的患病率信息。1988年全国健康访谈调查是对美国非机构化平民人口的横断面调查，在多阶段概率抽样中涵盖了47485户家庭中的122310人。该补充调查提供了基于人群的选定医疗设备患病率和发病率的首次估计。根据调查结果推算美国人口，估计有67.4万成年人使用81.1万个髋关节植入物。与一般成年人群相比，髋关节植入物接受者年龄更大、更有可能是白人，且教育、收入和活动水平更低。然而，按年龄分层后，仅活动受限和种族方面存在差异。目前髋关节置换手术的经济支出巨大。随着人口老龄化，除非采取措施减少置换手术需求，否则人工髋关节患者对医疗服务的使用可能会增加。这些措施包括减少受伤和改进生物材料。需要进一步调查以研究本研究中发现的活动受限和患病率的种族差异。
