Abstract：
OBJECTIVE: This study aimed to enrich the research on frailty trajectories by using FRAIL scale and frailty index (FI), and analyze the determinants of the different trajectories in older Chinese.
METHODS: 2268 older adults from the Chinese Longitudinal Healthy Longevity Survey were included. The FRAIL scale was constructed from 5 items and FI was constructed from 39 deficits. Latent Class Trajectory Model was used to depict frailty trajectories. Lasso - logistic model was applied to exploration of influencing factors.
RESULTS: Four FRAIL trajectories and three FI trajectories were identified. Women, smoking, illiteracy, more than two chronic diseases, and poor instrumental activities of daily living (all p < 0.05) were associated with frailty trajectories, regardless of the frailty instrument employed.
CONCLUSIONS: Frailty trajectories of older Chinese adults are diverse and they are influenced by different frailty measurement tools. Long-term assessment and management of frailty are recommended as routine care in community healthcare centers.

摘要：
目的：本研究旨在通过使用FRAIL量表和脆弱指数（FI）来丰富对脆弱轨迹的研究，并分析了中国老年人不同轨迹的决定因素。
方法：纳入了中国纵向健康长寿调查的2268名老年人。FRAIL量表由5个项目构成，FI由39个赤字构成。潜类轨迹模型用于描述脆弱轨迹。将Lasso-logistic模型应用于影响因素的探索。
结果：确定了四个FRAIL轨迹和三个FI轨迹。女人,吸烟,文盲,两种以上的慢性疾病，不良的日常生活工具活动(所有p<0.05)与虚弱的轨迹有关，不管使用的是脆弱的工具。
结论：中国老年人的虚弱轨迹是多样的，并且受到不同的虚弱测量工具的影响。建议将虚弱的长期评估和管理作为社区医疗保健中心的常规护理。
