目的:全球(营养)领导层倡议营养不良(GLIM)诊断标准(共识)调查国内结直肠癌住院患者营养不良的发生情况并探究及其与临床结局的相关性。方法:对2014年全国多中心前瞻性调查数据库中582例成年结直肠癌住院患者进行回顾性分析。应用不含肌肉量减少的GLIM标准进行营养不良诊断，观察结直肠癌患者营养不良的患病率，探索营养不良与并发症发生率、住院时间、住院费用的相关性。结果:582例患者中，入院时经GLIM诊断为营养不良195例(33.5%)。GLIM标准与主观全面营养评定评分存在正向的弱相关关系；营养不良与并发症发生率显著相关(n OR: 2.543，95% n CI：1.416～4.567)，经GLIM诊断营养不良的患者住院时间显著长于无营养不良患者(n P＝0.016)，两者住院费用差异无统计学意义(n P＝0.454)。n 结论:结直肠癌住院患者经GLIM标准诊断营养不良患病率为33.5%，GLIM标准适用于结直肠癌患者且与临床结局相关。“,”Objective:To investigate the prevalence of malnutrition in colorectal cancer patients and its correlation with clinical outcomes using the Global Leadership Initiative on Malnutrition (GLIM) criteria.Methods:A retrospective analysis was performed in 582 adult inpatients with colorectal cancer from the 2014 national multi-center survey database. The diagnosis of malnutrition was confirmed according to GLIM criteria (reduced muscle mass not included), the prevalence of malnutrition in colorectal cancer patients was observed, and the correlation between malnutrition and the incidence of complications, hospitalization duration, and hospital costs was explored.Results:Of the 582 patients, 195 (33.5%) were malnourished as per GLIM criteria at admission. There was a weak positive weak correlation between diagnosis as per GLIM criteria and subjective global assessment score. Malnutrition was significantly associated with the incidence of complications (odd ratios: 2.543, 95% confidence interval: 1.416-4.567), the hospitalization duration of malnourished patients was significantly longer than that of patients without malnutrition (n P=0.016), and the difference in hospitalization costs was not statistically significant (n P=0.454).n Conclusions:The prevalence of malnutrition as per of GLIM criteria in colorectal cancer inpatients was 33.5%, and malnourished patients ashowed a higher incidence of complications and a longer hospitalization duration than non-malnourished colorectal cancer patients. The GLIM criteria are applicable to patients with colorectal cancer and are associated with clinical outcomes.
