背景资料：过去的研究已经测量和描述了死亡前残疾的生命长度，但还没有研究可改变的生活方式因素和残疾持续时间之间的关系。目的：探讨是否存在影响死亡前残疾寿命长短的可变因素。研究方法：本研究设计阿萨性观察早期参加前瞻性队列研究的死者，在随访期间（1996-1999），我们记录了1994年基线调查时70-79岁的781例死亡（n = 10，216）。在2000年，我们采访了死者的家属对受试者的死亡前残疾的持续时间（n = 655）。结果：死亡前残疾的中位持续时间约为6个月。较高的体重指数（BMI）和较短的步行时间与长期残疾（超过6个月）的风险增加显著相关。与BMI <20相比，BMI 20-25的患者长期残疾的优势比为1.3，BMI >25的患者为2.1。与步行>1.0 h/d的患者相比，步行0.5-0.9 h/d的患者长期残疾的比值比为1.3，步行<0.5 h/d的患者为1.7。这些关系在死亡原因分层后没有变化。结论：控制体重和晚年步行可缩短死亡前残疾寿命。
Background: Past studies have measured and described the length of life with disability before death, but there has been no study of the relationship between modifiable lifestyle factors and duration of disability. Objective: To examine whether there are modifiable factors influencing the length of life with disability before death. Methods: The study was designed asa retrospective observation of the deceased who had earlier been enrolled in a prospective cohort study.During the follow-up period (1996–1999), we documented 781 deaths among those who were 70–79 years of age at the baseline survey in 1994 (n = 10,216). In 2000, we interviewed family members of the deceased about the duration of the subjects’ disability before death (n = 655). Results: The median duration of disability before death was approximately 6 months. Both higher Body Mass Index (BMI) and shorter time spent walking were significantly associated with an increased risk of long-term disability (more than 6 months). The odds ratios of long-term disability were 1.3 in those with BMI 20–25 and 2.1 in those with BMI >25, compared with BMI <20. The odds ratios of long-term disability were 1.3 in those walking for 0.5–0.9 h/day and 1.7 in those walking for <0.5 h/day, compared with those walking for >1.0 h/day. These relationships were unchanged after stratification for causes of death. Conclusion: Weight control and walking in later life may shorten the length of life with disability before death.
