The national food surveys of 1974, 1979 and 1989 were analysed in order to evaluate the levels and tendencies of the malnutrition prevalence in children one to five years old. The malnutrition prevalence maintained its level with minor changes: it increased from 49 to 53 per cent in the group with -1 SD, and from 17 to 19 per cent in those with -2 SD, in relation with the WHO [correction of OMS]-NCHS standards. If the information is analysed by social sectors, it is possible to conclude that the apparent stability is due to a process of nutritional polarization: the areas that had lower figures improved as the poor and Indian areas with high prevalence of initial malnutrition deteriorated even more.
对1974年、1979年和1989年的全国食物调查进行了分析，以评估1至5岁儿童营养不良患病率的水平和趋势。营养不良患病率维持在一定水平，仅有微小变化：按照世界卫生组织（WHO）-美国国家卫生统计中心（NCHS）标准，身高低于标准差-1的儿童组中，患病率从49%升至53%，身高低于标准差-2的儿童组中，患病率从17%升至19%。如果按社会部门分析这些信息，就可以得出结论，表面上的稳定是由于营养两极分化过程：原本数据较低的地区有所改善，而初始营养不良患病率较高的贫困和印第安地区则恶化得更严重。
