摘要
目的了解中国不同特征老年人的失能轨迹的差异,为改善老年人的日常生活自理能力提供参考依据。方法收集2005、2008和2011年中国老年健康影响因素跟踪调查项目的追踪数据,应用组基轨迹模型拟合出全国23个省(自治区、直辖市)65~105岁老年人的失能轨迹,分析不同特征老年人失能轨迹的差异。结果7 979名65~105岁中国老年人中,身体健全型老年人2 791人(34.98%),低起点高龄期迅速发展型老年人4 331人(54.28%),较高起点迅速发展型老年人857人(10.74%);存活、死亡、失访老年人失能轨迹比较,2011年不同状态老年人失能轨迹不同,差异有统计学意义(χ2=186.38,P<0.001);不同特征老年人失能轨迹比较,不同性别、出生队列、职业地位、居住地的老年人失能轨迹不同,差异均有统计学意义(均P<0.001)。结论中国老年人失能轨迹以低起点高龄期迅速发展型为主,不同性别、出生队列、职业地位、居住地的老年人失能轨迹存在明显差异。
Objective To investigate the difference in disability trajectories among the elderly with different charac- teristics in China and to provide references for reducing disability in Chinese elderly. Methods We extracted the data on 7 979 residents aged from 65 to 105 years living in 23 provinces and municipalities or autonomous regions from the re- suits of Chinese Longitudinal Healthy Longevity Survey conducted in 2005,2008, and 2011. We adopted group-based traj- ectory model to fit and compare the disability trajectories of the elderly with different characteristics. Results Of all the elderly surveyed,34. 98% （2 791 ） were identified with the trajectory of able-bodied,54. 28% （4 331 ） with the trajectory of mild disability at the beginning but rapid exacerbation in the late life, and 10.74% （ 857 ） with the trajectory of rela- tively severe disability at the beginning and then rapid exacerbation,respectively. Significantly different disability trajecto- ries were observed among the elderly being followed-up, passed away, and lost to follow-up based on the data of 2011 （X2= 186. 38 ,P 〈 0. 001 ）. The disability trajectories differed significantly by gender, birth year, occupation, and livingarea among the elderly （P 〈 0. 001 for all）. Conclusion Mild disability at the beginning but rapid exacerbation in the late life is a major pattern of disability trajectory and the trajectory is mainly influenced by gender, birth year, occupation, and living area among the elderly in China.
