This cohort is interesting because maybe they are receiving complementary foods and micronutrient supplements from public health programs in their first five years, and then school food security intervention programs. As Peru is one of the countries that have good advances in MDG first goal will be interesting to explore if catch-up growth has something to do with blood pressure in this population...

Do you think that socioeconomic variation (social classes) could directly or indirectly influence the studied population or could it be used to predict a successful nutritional program in your population?
