    近年来,由人类免疫缺陷病毒(HIV) 感染所致的获得性免疫缺陷综合征(AIDS) 的患病率在我国呈上升趋势。鉴于
我国医务工作者对艾滋病的诊治经验不多,因此提高对HIV感染的认识很有必要。据报道,在AIDS 患者中,98 %存在营养不良。[1]为此,本文结合近期文献对HIV 感染或艾滋病患者的营养不良发生机理、营养评估及其处理对策综述如下。

    1  营养不良发生机理
    发生营养不良主要有三个方面的原因:即经口摄入减少,物质代谢改变以及营养成分吸收障碍。
  1. 1  经口摄入减少

  1. 2  物质代谢的改变

  1. 3  吸收障碍

    2  营养状况的评估

  2. 1  病史

  2. 2  食欲

  2. 3  体重和身体各部位的测量

  2. 4  生化检验

    3  营养不良的护理

  3. 1  病因护理

  3. 1. 1  摄入减少

  3. 1. 2  物质代谢改变

  3. 1. 3  营养吸收障碍

  3. 2  临床护理

  3. 2. 1  对症护理

  3. 2. 2  一般营养指导
