摘　　要：作者调查了１６１例（男：９８，女：６３）中老年人的营养素摄入量、血浆蛋白及体液免疫水平。结果：该人群的大部分人热能的摄入量达ＲＤＡ值；膳食蛋白质、维生素Ａ、Ｂ２、Ｃ、锌和铁的摄入量较低；脂肪摄入量按热能比高于３０％者约占３０％；血浆总蛋白、球蛋白水平较低，尤其是女性；免疫球蛋白ＩｇＡ偏低，ＩｇＧ和ＩｇＭ偏高。Nutrient intake, serum protein cont ents and humoral immunity levels in 161(male : 98, female : 63) middle-aged and older aged people have been studied.The results show that the intake of energy has attained the RDA, but dietary protein, vitamin A,B2,C,Zn and Fe intakes are relatively low in most of the studied population. About 30% of the studtied population obtain energy from fat which are higher than 30% of the total energy. The contents of serum protein and globulin are relatively low, especially in females. Serum concentration of IgA is on the lower side of normal range, while serum concentrations of IgG and IgM are on the higher side.
