营养风险筛查在老年糖尿病肾病患者营养评估中的应用

The application of nutritional risk screening in nutritional assessments of elderly patients with diabetic nephropathy

目的应用营养风险筛查(NRS)2002对老年糖尿病肾病(DN)住院患者进行营养筛查,了解其营养不良的患病率,以确定营养干预的重点人群。方法采用NRS2002、同时测定体质量指数(BMI)及血清白蛋白(ALB)、前白蛋白(PA)、血肌酐(SCr)等生化指标,对168例老年糖尿病肾病住院患者进行营养评估,评价其营养状况,并进行相关性分析。结果 168例老年糖尿病肾病患者中,NRS2002评分≥3分存在营养不良风险者51例(30.4%),DNⅤ期患者营养不良风险发生率最高达62.5%,与DNⅢ期20.5%比较,差异有统计学意义(P<0.05);BMI<18.5 kg/m2者18例,营养不良的发生率为10.7%,ALB<30 g/L患者27例,营养不良的发生率为16.1%,NRS2002评分与BMI、ALB、PA、SCr有相关关系(P<0.05)。结论老年糖尿病肾病患者营养不良的发生率高,NRS2002是一种简单、有效的营养评估方法,能够早期发现存在营养不良风险的患者。

Objective To investigate the prevalence of malnutrition based on nutritional screening among elderly hospitalized patients with diabetic nephropathy （DN） by Nutritional risk screening 2002 （ NRS）, to determine the emphasis crowd of nutritional intervention. Method The nutritional status of 168 cases elderly hospitalized patients with DN were assessed by NRS2002, body mass index （BMI） , serum albumin （ ALB ） , prealbumin （ PA ） , serum creatinine （SCr） ete biochemical index. Results There were 51 cases （30.4%） with malnutrition risks （ NRS2002 score ≥ 3 points） among 168 cases of elderly patients with diabetic nepbropathy. The malnutrition prevalence of DN V patients was the highest,by 62.5%, significantly higher than DN Ⅲ patients group （20.5%）,the difference was statistically significant （ P 〈 0.05 ）. There were 18 cases with BMI 〈 18.5 kg/m^2, the prevalence of malnutrition was 10.7 %. There were 27 patients with ALB 〈 30 g/L, the prevalence of malnutrition wasl6.1%. NRS2002 is associated（P 〈 0.05） withbody mass index （BMI） , albumin （ ALB ）, prealbumin （PA） and serum creatinine （SCr）. Conclusions The prevalence of malnutrition is high in elderly patients with diabetic nephropathy. NRS2002 is a simple and efficient method of nutritional assessment elderly patients with diabetic nephropathy.
