Abstract：
Malnutrition is a critical issue among older inpatients, yet limited large-scale research related to this issue has been conducted in China. This study aimed to examine the nutritional status and support of older inpatients in China, assess the associations between disease categories and malnutrition on admission, and explore effective nutritional intervention.
A total of 24,139 older participants from the China Nutrition Fundamental Data 2020 Project were included. Malnutrition was measured by the Global Leadership Initiative on Malnutrition criteria. Adjusted odds ratios (aORs) were calculated using logistic analysis.
The overall frequency of malnutrition on admission was 18.9%. Participants with infections were more likely to have malnutrition (aOR = 1.929, 95% CI 1.486-2.504). Risks that were also noted for malnutrition included neoplasms (aOR = 1.822, 95% CI 1.697-1.957), hemic and lymphatic diseases (aOR = 1.671, 95% CI 1.361-2.051), nervous system diseases (aOR = 1.222, 95% CI 1.126-1.326), respiratory diseases (aOR = 1.613, 95% CI 1.490-1.746), and digestive system diseases (aOR = 1.462, 95% CI 1.357-1.577). Further, 32.26% inpatients with malnutrition during hospitalization didn\'t receive nutritional support. Oral nutrition supplements, enteral tube feeding, and parenteral nutrition were associated with stable or improved nutritional status.
Older inpatients were at a high risk for malnutrition but did not receive adequate nutritional intervention. More resources and attention need to be devoted to the nutritional status of older inpatients and targeted nutritional support.

摘要：
背景：营养不良是老年住院患者的一个关键问题，然而，在中国，与这个问题相关的大规模研究有限。本研究旨在调查中国老年住院患者的营养状况和支持，评估入院时疾病类别与营养不良之间的关联，探索有效的营养干预措施。
方法：纳入了来自中国营养基础数据2020项目的24,139名老年参与者。营养不良是根据全球营养不良领导倡议标准来衡量的。使用逻辑分析计算调整后的比值比（aOR）。
结果：入院时营养不良的总发生率为18.9%。感染的参与者更容易营养不良（aOR=1.929，95%CI1.486-2.504）。营养不良的风险也包括肿瘤（aOR=1.822，95%CI1.697-1.957），血液和淋巴疾病（aOR=1.671，95%CI1.361-2.051），神经系统疾病（aOR=1.222，95%CI1.126-1.326），呼吸系统疾病（aOR=1.613，95%CI1.490-1.746），和消化系统疾病（aOR=1.462，95％CI1.357-1.577）。Further,32.26%住院期间营养不良患者未接受营养支持。口服营养补充剂，肠管喂养，肠外营养与营养状况稳定或改善相关。
结论：老年住院患者营养不良的风险很高，但没有接受足够的营养干预。需要将更多的资源和注意力投入到老年住院患者的营养状况和有针对性的营养支持上。
