老年糖尿病患者的营养状态和感染

Study on the relationship of infection and nutrition status on elderly patients with type 2 diabetes

目的了解合并感染与不合并感染的老年糖尿病患者间营养状态的差别,观察营养状态对感染的影响,以期减少感染发生率。方法运用微量营养评估表(MNA)进行评分,同时检测血清白蛋白,前白蛋白、胆固醇、甘油三酯、C-反应蛋白、糖化血红蛋白、淋巴细胞计数,测量并计算体重指数、三头肌皮褶厚度、上臂肌围。结果两组糖尿病患者间的MNA评分、上臂肌围、淋巴细胞计数、白蛋白和前白蛋白差异存在显著性(P<0.05),感染组低于未感染组。结论老年糖尿病患者由于蛋白质营养不良,易于合并感染,而感染将进一步加重营养不良,造成恶性循环。改善糖尿病患者的营养状态对降低糖尿病患者的感染发生率有益。

Objective To explore the difference of nutrition status between the elderly patients with type 2 diabetes mellitus complicated with infection and those without infection . Methods The mini nutritional assessment method （MNA） was adopted and BMI was measured, triceps skin - flod thickness, aim muscle circumference and serum albumin, prealbumin, total lymphocyte count, C - reactive protein, triglyceride, cholesterol, glycesylated hemoglobin were measured to evaluate the nutrition status of elderly patients with type 2 diabetes complicated with infection and without infection. Results The MNA score, triceps skinfold thickness, total lymphocyte count, serum albumin and prealbumin of elderly patients with type 2 diabetes complicated with infection were lower than those of patients without infection. Conclusion Elderly patients with type 2 diabetes tend to complicate infection because of protein malnutrition. Improving their nutrition status would help to reduce incidence of complication with infection for elderly patients with type 2 diabetes .
