为研究复合营养素补充剂对老年人健康的影响 ,将 2 10名农村老年人分为对照组和试验组 ,试验组连续补充 5个月复合营养素补充剂 ,对照组食用安慰剂 ,补充前后分别测量身高、体重、生化、免疫等指标。用t检验和卡方检验 ,统计两组各项指标的差异。结果显示 ,补充复合营养素补充剂后 ,试验组血红蛋白水平显著高于对照组 (P <0 0 5 ) ,贫血患病率明显降低 ,血清维生素A水平、负荷尿维生素B2 、维生素C排出量均明显高于对照组 (P <0 0 5 )。提示复合营养素补充剂对改善中老年人贫血状况及改善维生素A、维生素B2 和维生素C营养状况有明显促进作用
In order to study the effect of compound nutrient supplements on the health of the elderly, 210 rural residents were divided into control group and trial group. The trial group was supplemented continuously for 5 months with the compound supplements. The control group was given placebo and the supplement was measured before and after Height, weight, biochemical, immune and other indicators. Using t-test and chi-square test, statistical differences between the two groups of indicators. The results showed that the level of hemoglobin in the experimental group was significantly higher than that in the control group (P <0.05), and the prevalence of anemia was significantly decreased. The levels of serum vitamin A, urinary vitamin B2 and vitamin C were significantly decreased Higher than the control group (P <0 05). It is suggested that the supplementation of compound nutrients can significantly improve the anemia in middle-aged and elderly people and improve the nutritional status of vitamin A, vitamin B2 and vitamin C.
