消化道恶性肿瘤患者术前营养风险相关因素分析

目的 了解消化道恶性肿瘤患者的术前营养风险状况,分析营养风险相关因素.方法 方便取样方法选择2012年2月1日至4月20日在北京肿瘤医院胃肠外科、结直肠外科及胸外科住院拟行根治性手术的223例消化道恶性肿瘤患者为研究对象,采用营养风险筛查2002（nutritional risk screening 2002,NRS2002）评估患者的营养风险,收集患者的一般资料和疾病相关资料.采用SPSS 16.0统计软件包进行原始数据的录入与分析.结果 本组患者营养风险得分为2.9±1.2,有109例术前发生营养风险,营养风险发生率为48.9％.多因素Logistic回归分析发现,营养风险的相关因素为年龄≥60岁（OR=1.080）和有更多症状（OR=1.157）.结论 消化道恶性肿瘤患者营养风险发生率较高,年龄越大、症状越多的患者越容易发生营养风险,对老年人及入院症状多的患者应给予及时有效的营养干预措施.

Study on nutritional risk and related factors among digestive tract cancer patients before surgery

Objective To describe digestive tract cancer patients＇ nutritional risk.To analyze factors related to nutritional risk.Methods Two hundred and twenty three digestive tract cancer patients who would undergo radical surgeries were enrolled by convenient sampling in Gastrointestinal Surgery Department and Thoracic Surgery Department of Perking University Cancer hospital from February to April,2012.Nutritional risk screening 2002 was used to assess the nutritional risk of the patients; Demographic data,disease related factors were collected.All data were analyzed by the SPSS 16.0 statistical software package.Results The score of nutritional screening was 2.9 ±1.2.One hundred nine patients were at nutritional risk,and the nutritional risk rate was 48.9%.Multivariate Logistic regression analysis indicated that patients who were older than or equal to 60 years （OR =1.080） and patients who had more symptoms （OR =1.157） were the related factors of nutritional risk.Conclusions Nutritional risk in digestive tract cancer patients is high.Patients whose ages are equal to or older than 60 and patients who have more symptoms are more likely to have nutritional risk.For the old patients or patients who have more symptoms,we should give effective nutritional interventions.
