目的 分析老年人内在能力（intrinsic capacity，IC）的潜在类别与口腔衰弱（oral frailty，OF）的相关性，为护理人员开展早期筛查、风险评估和个体化干预提供依据。方法 2024年11-12月，便利抽样法选取在上海市某社区医院参加体检的482例老年人为研究对象，采用一般资料调查表、IC评估工具、口腔衰弱指数-8量表对其进行调查。采用Mplus 8.3软件进行潜在类别分析，采用Logistic回归分析老年人IC潜在类别与OF的相关性。结果 老年人IC分出3个潜在类别：运动受损严重组（35.68%）、感觉受损严重组（22.82%）、多维功能受损组（41.49%）。结果显示，OF发生风险在多维功能受损组是运动受损严重组的1.739倍（95%CI：1.129~2.678）。结论 老年人OF的发生率较高，IC多维功能受损与OF呈显著相关，提示两者可能存在密切联系，建议医护人员关注存在IC多维度受损的老年人，采取针对性措施预防OF的发生。

Objective To analyze the latent classes of intrinsic capacity (IC) in older adults and their correlation with oral frailty (OF),and to provide a basis for nursing staff to conduct early screening,risk assessment,and individualized intervention.Methods From November to December 2024,a convenience sampling method was used to select 482 older adults who underwent physical examinations at a community hospital in Shanghai as the study subjects.A general information questionnaire,the IC Assessment Tool,and the Oral Frailty Index-8 Scale were used for the investigation.Mplus 8.3 software was employed for latent class analysis,and logistic regression was used to analyze the correlation between IC latent classes and OF in older adults.Results 3 latent classes of IC were identified in older adults:severe motor impairment group (35.68%),severe sensory impairment group (22.82%),and multi-dimensional functional impairment group (41.49%).The results showed that the risk of OF in the multi-dimensional functional impairment group was 1.739 times higher than that in the severe motor impairment group (95% CI:1.129-2.678).Conclusions The incidence of OF is relatively high in older adults,and multi-dimensional functional impairment of IC is significantly correlated with OF,suggesting a close relationship between the two.It is recommended that healthcare professionals pay attention to older adults with multi-dimensional IC impairment and take targeted measures to prevent the occurrence of OF.
