I have looked in the World Bank, UNICEF and even in the National Institute of Statistics of Spain, but all I get are numbers from some years, not a progression of years worth of data.
I also go through world bank, UNICEF and other source, but updated data of children malnutrition in Spain was not available. I think, you can contact some primary schools in Spain and you can get the data related to malnutrition. In hospital means, you will get only the new born details (birth weight and etc.,)
So, kindly contact some primary school and goahead your study.

Prof. Avilés after seeing your request Resarchgate, I remembered that a few weeks ago I read a story in the Spanish media on the subject. I searched the link and send it. It is in Spanish. But I guess you will not have trouble reading it. It's just a press release. But is published in a major newspaper of Spain. The news says that in Spain there are no national statistics on malnutrition.
In any case you may want to read the review. This speaks of some administrations (mainly northern Spain) which produce this type of data.
If the news is true (I repeat: it is only press) perhaps you could contact the authorities and / or municipalities to verify what type of data available.
Un saludo ... desde Asturias (a 20 kilómetros de Avilés).
I believe that malnutrition in a industrial country is hard to report as most parents will avoid to show that they can not feed properly their chldren, and probably most of them will no find social help to do it. Or even if they end in a social center to bring food for their home, there will be a lack of knowledge on whats the best way to use that food to provide utrients to their children.
At the same time, I dont thing Spanish government is (or was) interested in finding out and showing the real data.
Also, Non Government institutions and associations may increase the real data, while Government would probably decrease the real data.
That could make impossible to obtain real data for child malnutrition, as some will want to exaggerate the problem while other will want to mask them.
This article reports that there is no scientific evidence of child malnutrition:
I wanted to compare statistics between Spain and Mexico on the topic of children malnutrition. I understand your reasoning, I guess I will have to go with the few I find here and there.
It is better to contact either at FAO (Food and Agriculture organisation), or World Bank reports, IFPRI (INTERNATIONAL FOOD POLICY RESEARCH INSTITUTE) or Nutrition departments of Spain.
