老年人贫血及营养状况分析

目的 观察分析老年人贫血发生率及营养状况.方法 选择门诊健康查体的离退休老年人2052例,按年龄分为4组,65～69岁(528例)、70～74岁(593例)、75～79岁(423例),≥80岁(508例),检测体质指数(BMI)、血红蛋白(Hb)、红细胞平均体积(MCV)、三酰甘油(TG)、血肌酐(Cr)、血浆白蛋白(ALB)、血清铁蛋白(Fer)等指标,统计贫血发生率及对各营养指标进行分析.结果 (1)老年人贫血发生率为4.4%,其中男性4.0%,女性6.1%,＞80岁组为9.5%.Hb＜90 g/L者5例,均为80岁以上高龄患者.(2)各年龄组营养相关指标BMI、TG、Cr、ALB、Hb、MCV、Fer差异有统计学意义(均P＜0.01),且Hb、ALB在4组间差异有统计学意义(均P＜0.01),TG、Cr、MCV在多组间差异也有统计学意义(均P＜0.05).(3)经Pearson相关性分析,Hb与TG、ALB、Fer、MCV呈正相关,相关系数r值分别为0.12、0.21、0.11、0.10(均P＜0.01).结论 老年人随着年龄增长,贫血发生率逐渐增加,女性多于男性,尤以80岁以上高龄者发生率最高,且营养状况随着年龄增长而逐渐恶化.

Abstract：

Objective To observe the incidence rate of anaemia and analyze the nutritional situation in the elderly population.Methods From April to August 2010,a total of 2052 elderly persons from out-department of Tianjin First Center Hospital were divided into four age groups:65-69years group (n=528),70-74 years group (n=593),75-79 years group (n=423) and 80 years and over group (n= 508).The body mass index (BMI),haemoglobin (Hb),mean corpuscular volume (MCV),triglyceride (TG),creatinine (Cr),serum albumin (ALB) and ferritin (Fer) were tested and evaluated using K-W test.Results (1) Anaemia was found in 90 subjects (4.4 %),4.0% in men and 6.l% in women,9.5% in 80 years and over group.The subjects with Hb level less than 90g/L were all 80 years and over.(2)There were significant differences among the groups in BMI,TG,Cr,ALB,Hb,MCV and Fer levels (all P＜0.01).There were significant differences among four groups in Hb and ALB levels (P＜0.01 ),and partially differences in TG, Cr and MCV levels (P＜0.05).(3)The Hb level was significantly correlated with TG, ALB, Fer and MCV levels (r=0.115,0.211, 0.114 and 0.089, all P＜0.01 ) from Pearson analysis.Conclusions Anemia incidence in elderly population is increased along with aging and is higher in women than in men, especially higher in 80 years and over group.Nutritional situation gets worse with aging.
