(1) Background: Due to rapidly increasing average age of Taiwan's population, it is very important to analyze the factors affecting the survival of older adults. (2) Methods: In this study, the 1989 Taiwan Longitudinal Study on Aging, which lasted 22 years and consisted of seven surveys, was used. Furthermore, Cox and Aalen's time-dependent frailty models were used to analyze factors that affect the survival of older adults. (3) Results: Based on past literature, we selected 15 important factors that were closely associated with the survival of older adults and constructed six models based on these factors. The study results showed that, in addition to background characteristics, physical and mental conditions, activities of daily living (ADL), physical performance, and self-rated health had a huge association with the survival of older adults. (4) Conclusions: We selected ten variables (age, gender, population, education level, ADL status, physical performance, self-rated health, smoking, chewing betel nut, and the presence of a spouse), and their combinations were used to generate reduced models, which could be considered as important markers that affect and predict the survival of older adults.
(1) 背景：由于台湾人口平均年龄迅速增长，分析影响老年人存活的因素非常重要。(2) 方法：本研究使用了持续22年、包含七次调查的1989年台湾老年纵向研究。此外，采用Cox和Aalen的时间相依脆弱模型来分析影响老年人存活的因素。(3) 结果：基于以往文献，我们选择了15个与老年人存活密切相关的重要因素，并基于这些因素构建了六个模型。研究结果表明，除背景特征外，身体和精神状况、日常生活活动（ADL）、身体机能及自评健康与老年人的存活有极大关联。(4) 结论：我们选择了十个变量（年龄、性别、人口、教育水平、ADL状况、身体机能、自评健康、吸烟、嚼槟榔及配偶状况），并利用它们的组合生成简化模型，这些模型可被视为影响和预测老年人存活的重要指标。
