Abstract: With the accelerating trend of global population aging, intrinsic capacity has gained increasing attention as a core metric of healthy aging. Intrinsic capacity encompasses the composite of an individual's physical and mental abilities, specifically comprising five dimensions: cognition, locomotion, vitality (nutrition and metabolism), sensory (vision and hearing), and psychology. Decline in intrinsic capacity is strongly associated with adverse outcomes such as frailty, disability, falls, hospitalization, and death. Establishing a scientifically valid and effective system for the early screening and assessment of intrinsic capacity is therefore crucial for maintaining functional status in older adults and promoting healthy aging. Currently, China lacks standardized consensus on intrinsic capacity screening and comprehensive assessment protocols. To address this gap, the Chinese Geriatrics Society and the National Clinical Research Center for Geriatric Diseases (Xuanwu Hospital) spearheaded the development of this consensus. Based on evidence-based medicine and utilizing the GRADE framework for evidence grading this consensus systematically integrates the latest research. It aims to establish a scientific and standardized screening and comprehensive assessment system for intrinsic capacity, implement strategies for early identification and dynamic monitoring, and ultimately provide a reference for delaying the decline of intrinsic capacity and maintaining functional independence.

摘要： 随着全球人口老龄化进程的加速，内在能力作为健康老龄化的核心指标日益受到学界关注。内在能力是个体全部生理和心理能力的总和，具体涵盖认知、运动、活力（营养代谢）、感觉（视力与听力）和心理 5 个维度。内在能力下降与衰弱、失能、跌倒、住院以及死亡等多种不良结局显著相关。建立科学有效的内在能力早期筛查与评估体系，对于维护老年人功能状态、促进健康老龄化具有重要意义。目前，我国尚缺乏内在能力筛查与综合评估规范化共识。为此，中华医学会老年医学分会、国家老年疾病临床医学研究中心（宣武医院）牵头组织本共识的制订工作。本共识基于循证医学证据，采用 GRADE 证据分级，系统整合国内外最新研究，旨在构建科学、规范的内在能力筛查与综合评估体系，建立早期识别和动态监测方案，以期为延缓老年人内在能力下降和维持功能独立性提供参考。
