摘要
目的 分析≥80岁高龄老年人血中微量元素含量并与＜60岁非老年人进行比较,对≥80岁高龄老年长期卧床与非卧床患者血中微量元素含量及总蛋白、白蛋白、血红蛋白量进行对比分析. 方法 采用北京博晖BH5100型原子吸收光谱仪测定≥80岁高龄老年人及＜60岁非老年人血中微量元素,并进行统计学分析;同时测量高龄老年人总蛋白、白蛋白、血红蛋白并进行统计学分析. 结果 高龄老年人血中铁、锌、钙、铜、镁含量分别为（7.21±1.21） mmol/L、（93.29±10.96）mmol/L、（1.63±0.21） mmol/L、（17.31±3.61）mmol/L、（1.49±0.20） mmol/L;对照组分别为（8.91±1.25） mmol/L、（121.85±11.24） mmol/L、（1.51±0.23） mmol/L、（15.89±3.87） mmol/L、（1.51±0.21）mmol/L;高龄老年人血中铁、锌、钙、铜缺乏率分别为42.9％、14.3％、21.4％、14.3％,对照组分别为9.1％、13.6％、31.8％、27.3％;高龄老年人铁含量较非老年人组低,铁缺乏较非老年人多;而非老年人钙、铜含量较高龄老年人低,钙、铜缺乏者较高龄老年人多,差异均有统计学意义（P＜0.01）.长期卧床高龄老年人血中铁、锌、钙、铜、镁含量分别为（6.44±0.89） mmol/L、（84.48±8.98）mmol/L、（1.71±0.19） mmol/L、（17.50±3.57）mmol/L、（1.45±0.18） mmol/L;非卧床高龄老年人分别为（8.16±1.16） mmol/L、（103.62±10.31） mmol/L、（1.57±0.23） mmol/L、（17.08±3.59）mmol/L、（1.54±0.21） mmol/L;长期卧床高龄老年人血中铁、锌、钙、铜缺乏率分别为60.9％、18.8％、13.0％、13.0％,非卧床组分别为21.1％、8.8％、31.6％、15.8％;长期卧床高龄老年人铁、锌含量较非卧床高龄老年人低,铁缺乏者较非卧床高龄老年人多;非卧床高龄老年人钙含量较长期卧床高龄老年人低,钙缺乏者较长期卧床高龄老年人多,各组差异均有统计学意义（P＜0.01）;铜缺乏两组相似,差异无统计学意义（P＞0.05）;各组均无镁缺乏者.长期卧床高龄老年人总蛋白（62.8±3.9）g/L、白蛋白（33.7±2.6）g/L、血红蛋白（109.0±12.5）g/L,均较非卧床老年人低[总蛋白（66.3±1.7）g/L、白蛋白（36.7±1.8）g/L、血红蛋白（132.0±5.21）g/L],差异有统计学意义（P＜0.01）.结论 高龄老年人,尤其是长期卧床高龄老年人以铁缺乏为主,非卧床高龄老年人以钙缺乏为主;长期卧床高龄老年人总蛋白、白蛋白、血红蛋白均较非卧床高龄老年人低.
Objective To compare the serum microelement changes between patients aged ≥80years and adults aged 〈 60 years,and to compare the levels of serum microelement,total protein,albumin,hemoglobin between the long term in-bed and non in-bed oldest patients.Methods Beijing Bohui BH5100 type atomic absorption spectrometer was used to determine serum microelement.Total protein,albumin,hemoglobin were also determined.Results The amounts of ferrum,zinc,calcium,copper,magnesium were （7.21 ± 1.21） mmol/L,（93.29 ± 10.96）mmol/L,（1.63 ± 0.21）mmol/L,（17.31±3.61）mmol/L,（1.49±0.20）mmol/L in people aged over 80 years,（8.91±1.25）mmol/L,（121.85±11.24）mmol/L,（1.51±0.23）mmol/L,（15.89±3.87）mmol/L,（1.51±0.21）mmol/L in people aged less than 60 years,respectively.The ratios of Ferrum deficiency were 42.9 %,zinc deficiency 14.3%,calcium deficiency 21.4%,copper deficiency 14.3% in oldest-old,whereas were 9.1%,13.6 %,31.8%,27.3% in people aged less than 60 years.The amount of ferrum was significantly lower in people aged over 80 years than in people aged less than 60 years （P〈0.01）.Proportion of ferrum deficiency was higher in patients aged over 80 years （P〈0.01）.The amount of calcium and copper was markedly lower in people aged less than 60 years than in people aged over 80 years （P〈0.01）.The proportions of calcium,copper deficiency were higher in people aged less than 60 years （P〈0.01）.The amounts of ferrum,zinc,total protein,albumin,hemoglobin of the patients aged over 80 years in long-term in-bed group were significant decreased as compared with those of people in non long-term in-bed group [（6.44±0.89）mmol/L vs.（8.16±1.16）mmol/L,（84.48±8.98）mmol/L vs.（103.62±10.31）mmol/L,（62.8±3.9）g/L vs.（66.3±1.7）g/L,（33.7±2.6）g/L vs.（36.7±l.8）g/L,（109.0±12.5）g/L vs.（132.0±5.2）g/L,all P〈0.01].The amount of calcium of people in none long-term group was much lower [（1.57±0.23）mmol/L vs.（1.71±0.19）mmol/L,P〈0.01].Ferrum,zinc,calcium and copper deficiencies were 60.9%,18.8%,13.0%,13.0% in long-term in-bed group,21.1%,8.8%,31.6%,15.8% in non long-term in-bed group.Proportion of ferrum deficiency was higher in long term in-bed group than non long-term in-bed group （P〈0.01）.Proportion of calcium deficiency was higher in non long-term in-bed group than long-term in bed group （P〈0.01）.There was no significant difference in the amount of copper between people in long term in bed group and non long-term in-bed group （P〉0.05）.There was no absence of magnesium in both two groups.Conclusions There is more absence of ferrum,zinc,total protein,albumin,hemoglobin in the patients aged 80 years and over in long-term in-bed.There is more calcium and copper absence of people aged less than 60 years.So it is necessary to supply high ferrum food and nutrients in order to get well sooner,especially to patients aged over 80 years.
