Abstract: Objective To measure the levels of serum proteins and hemoglobin in children with pneumonia,and to analyze the nutritional status in children. Methods A total of 153 children with pneumonia were divided into three groups matched by age:0~1 years old group;1~<3 years old group;3~12 years old group.The level of serum total protein(TP),albumin(ALB),prealbumin(PA),retinol binding protein(RBP),hemoglobin (HB) were measured. Results The total prevalence of hypoproteinemia in children with pneumonia was 25%.The prevalences of hypoproteinemia in 0~1 years old group,1~<3 years old group and 3~12 years old group were 41%,15%,7% respectively.The prevalence of hypoproteinemia was significantly higher in 0~1 years old group than that in 3~12 years old group(P<0.05).There was no significant difference in the prevalence of hypoproteinemia between 1~<3 years old group and 3~12 years old group.The total prevalence of anemia in children with pneumonia was 63%.The prevalence of anemia in 0~1 years old group,1~<3 years old group and 3~12 years old group were 72%,78%,28% respectively.The prevalence of anemia was significantly higher in 0~1 years old group than that in 3~12 years old group(P<0.05).The prevalence of anemia was significantly higher in 1~<3 years old group than that in 3~12 years old group (P<0.05). Conclusions The prevalence of hypoproteinemia and anemia in infants with pneumonia was higher than that in aged 3~12 years old children.Therefore,the nutritional status of children especially infants with pneumonia should be closely monitored,and proper nutritional support should be provided when necessary to improve the prognosis.

摘要： 目的 测定肺炎患儿血浆蛋白质及血红蛋白的水平,对患儿的营养状况进行初步分析。方法 根据年龄将153例肺炎患儿分三组:<1岁年龄组;1~<3岁年龄组;3~12岁年龄组。对其血浆总蛋白、白蛋白、前白蛋白、视黄醇结合蛋白、血红蛋白进行检测。结果 153例肺炎患儿的低蛋白血症患病率为25%,<1岁年龄组患儿低蛋白血症患病率为41%,<3岁年龄组为15%,3~12岁年龄组为7%。<1岁年龄组患儿的低蛋白血症患病率高于3~12岁年龄组,差异有统计学意义(P<0.05)。1~<3岁年龄组患儿的低蛋白血症患病率高于3~12岁年龄组,但差异无统计学意义。153例肺炎患儿的贫血患病率为63%,<1岁年龄组患儿的贫血患病率为72%,<3岁年龄组为78%,3~12岁年龄组为28%。<1岁年龄组患儿的贫血患病率高于3~12岁年龄组,差异有统计学意义(P<0.05)。1~<3岁年龄组患儿的贫血患病率高于3~12岁年龄组,差异有统计学意义(P<0.05)。结论 肺炎患儿中,婴幼儿的低蛋白血症及贫血的患病率较大年龄组高。因此,应尽早监测肺炎患儿尤其是婴幼儿营养状况变化,及时进行营养支持,以改善患儿预后。
