高海拔地区婴幼儿生长发育与缺氧及营养的关系

THE RELATIONSHIP BETWEEN THE INFANTILE GROWTH AND THE FACTORS OF HYPOXIA AND NUTRITION AT HIGH ALTITUDES

我们对海拔２２６１～２８３５ｍ婴幼儿生长发育与缺氧及营养的关系进行了研究，结果说明孕妇在妊娠后期吸氧和吃营养品后，不仅增加新生儿的出生体重，而且在生后１～１、５岁以前的生长发育仍然较对照组好。婴幼儿常见的营养性疾病如贫血和佝偻病的发病与母亲妊娠期缺氧和营养缺乏有明显的关系，当孕妇在妊娠后期吸氧和补充营养品后，两种疾病的发病率明显降低。因此提示影响婴幼儿生长发育的因素不仅是高原缺氧，营养也是一种重要因素。

Due to the hypoxia,the cold weather and the lack of nutritive foods stipply such as the freshvegetables and fruits at the high altitudes,the growthand development are retardation than theinfants at the plain area.In order to improve the health care of the infants at high aItitudes,We studied the relation-ship between the infantlie growth and of hypoxia and nutrition at the areas from 2 261 to 2 835meters above sea level The results showed that the pregnant women inhaled more oxygen and got more nutritivefoods at the later pregnant period,it not only increase the newborn birth weight,but also improvetne infantile growth during 1～1.5years,beside this,the morbidity of nutritive anemia and ricketsare declined than the control groups.The article suggests:the factors which influence infantile growth at high altitudes,except thehypoxia,the deficiency of nutrition also is a important cause.It must be enhanced the health careand guided the baby feeding to compensate the hypoxia effects to infantile growth at high alti-tudes
