摘要
目的:探讨补充复合营养素对中老年人营养和免疫状况的影响。方法:选择50～65岁的中老年人志愿者,分两组,实验组服用复合营养素片,对照组服用安慰剂。实验开始和结束时分别进行体格测量、血液生化和免疫指标测定。结果:试验前对象,身高、体重和营养素摄入、血液生化指标和免疫指标两组均无差异(P﹥0.05)。6个月后,实验组血清维生素A(VA)、血清锌(Zn)和全血硒(SE)高于对照组;体液免疫指标血清IgA、IgG、IgM、补体C3高于对照组(均P<0.05),细胞免疫指标两组无差别(P>0.05)。结论:复合营养素补充剂能改善中老年人VA、Zn、Se营养状况,并能促进体液免疫功能。
Objective： To explore the impact of compound nutrients supplementation on nutritional and immune status in middle-aged and elderly people. Method： The volunteers aged 50-65 years old were randomized into two groups. The supplement was given to the test group, the control group took placebo. Results： In comparison with the control group, the test group had a higher level of serum vitamin A and zinc, blood selenium. The humoral immune indices as IgA, IgG, IgM, C3 of the test group were higher than those of the control group, but no significant difference of cellular immunity indices between two groups. Conclusion： Supplementation of compound nutrients could improve the nutritional status of vitamin A, zinc and selenium, and may promote humoral immunity.
