Basic characteristics of the study participants.

It is important to establish the relationship between appropriate nutritional intake and improvements in activities of daily living (ADLs) in elderly hospitalized patients. This prospective observational study aimed to investigate diet order compliance (DOC) during 8 weeks of hospitalization and calculate the odds of improved functional independence measure (FIM) scores for high- and low-DOC groups using covariate-adjusted models in geriatric convalescent hospitals. The study subjects were elderly inpatients (>65 years old) with degenerative disease who consumed prescribed oral meals (Functional Oral Intake Scale (FOIS) = 6/7) and who did not receive physical/occupational therapy. The personalized diet order was prescript, and the DOC was calculated using dietitian-monitored daily intake data. The 73 patients were divided into a low-DOC group (明确住院老年患者适宜营养摄入与日常生活活动（Activities of Daily Living，ADLs）能力改善之间的关联，具有重要意义。本项前瞻性观察研究以老年康复医院的住院患者为研究对象，旨在探究其住院8周期间的医嘱饮食依从性（Diet Order Compliance，DOC）情况，并通过协变量校正模型，计算高、低依从性组患者的功能独立性评定量表（Functional Independence Measure，FIM）评分改善的优势比。本研究的研究对象为年龄大于65岁的退行性疾病住院老年患者，其可按医嘱进食口服膳食（功能性口腔进食量表（Functional Oral Intake Scale，FOIS）评分为6/7分），且未接受物理治疗或作业治疗。本次研究的个性化饮食医嘱为预先制定，而DOC则通过营养师监测的每日膳食摄入数据进行计算。本研究共纳入73例患者，并将其划分为低依从性组（
