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.
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.
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.
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.
本研究旨在使用 FRAIL 量表和衰弱指数（FI）丰富衰弱轨迹的研究，并分析中国老年人不同轨迹的决定因素。
本研究纳入了 2268 名来自中国健康长寿纵向研究的老年人。FRAIL 量表由 5 项组成，FI 由 39 项缺陷组成。采用潜在类别轨迹模型描述衰弱轨迹。应用套索 - 逻辑回归模型探索影响因素。
确定了 4 种 FRAIL 轨迹和 3 种 FI 轨迹。无论使用何种衰弱测量工具，女性、吸烟、文盲、患有两种以上慢性疾病和日常生活活动能力差（均 P < 0.05）与衰弱轨迹相关。
中国老年人的衰弱轨迹是多样的，受不同的衰弱测量工具影响。建议在社区医疗中心常规护理中进行长期衰弱评估和管理。
