EXERCISE, DISABILITY, OSTEOARTHRITIS AND COSTS

描述：(改编自《调查者摘要》)身体残疾是 老龄化人口最普遍的主要健康问题，以及与之相关的 对医疗服务的需求很大。然而，尽管对风险的纵向研究 心血管疾病的因素已经确定了主要的可改变的风险 因素，并导致了降低发病率和死亡率的战略， 这类肌肉骨骼疾病的研究仍处于初级阶段。这20年 1984年对961名平均年龄为58岁的人进行的纵向研究 由于2004年将达到78岁，将(1)确定身体健康的危险因素 残疾、放射性骨关节炎和相关的医疗服务使用， (2)评估运动和其他危险因素的变化 终生残疾和随时间累积的卫生保健利用率，以及(3) 建立骨质疏松性骨折的危险因素模型。体育运动的作用 特别强调锻炼。调查人员将评估事态的发展 少数群体的残疾、残疾进展和危险因素模型 与以白人为主的非西班牙裔人口相比。调查人员 声明这个项目是由大量的前期工作和唯一的数据支持的 准备好了。他们指出，该申请将他们的调查范围扩大到 累积发病率和费用、费用分析等重要新问题 和福利、长期残疾和成本结果、少数群体的风险因素 以及危险因素状态的变化对残疾的影响， 成本和死亡率结果。应用程序建议继续数据 收购进入第八和九十年，这群人将 经历最大程度的残疾、健康下降和使用 医疗服务。调查人员表示，调查结果将表明公众 旨在减少终生发病率和医疗保健的政策举措 通过预防机制减少可改变的风险因素来降低成本。他们 进一步指出，总体项目目标是了解如何 运动和其他危险因素状态的改善可能会延缓功能 减少和减少对医疗保健的需求。

DESCRIPTION: (Adapted from Investigator's Abstract) Physical disability is the most prevalent major health problem of aging populations, and the associated needs for medical services are large. Yet, while longitudinal studies of risk factors for cardiovascular disease have identified major modifiable risk factors and have led to strategies for reduction of morbidity and mortality, such studies in musculoskeletal disease remain in their infancy. This 20 year longitudinal study of 961 individuals studied from an average age of 58 in 1984 and due to reach age 78 in 2004 will (1) identify risk factors for physical disability, radiologic osteoarthritis, and associated use of medical services, (2) assess changes in exercise and other risk factors in terms of cumulative lifetime disability and cumulative health care utilization over time, and (3) establish risk factor models for osteoporotic fractures. The role of physical exercise is particularly emphasized. The investigators will assess development of disability, progression of disability, and risk factor models in minority as compared with predominately white non-Hispanic populations. The investigators state that this project is enabled by extensive previous work and a unique data set. They point out that the application extends their investigations into important new questions of cumulative morbidity and costs, analysis of costs and benefits, long-term disability and cost outcomes, risk factors in minority populations, and effects of changes in risk factor status upon disability, cost, and mortality outcomes. The application proposes to continue data acquisition into the eighth and ninth decades, the age when this cohort will experience the greatest degrees of disability, decline in health, and use of health services. The investigators state that the results will suggest public policy initiatives directed at decreasing lifetime morbidity and medical care costs through preventive mechanisms which reduce modifiable risk factors. They further state that the overall project objective is to understand how improvements in exercise and other risk factor status may retard functional decline and reduce the need for medical care.
