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.
Many thanks indeed for your comment. Unfortunately, with our current design, we will not be able to disentangle the effect of such food nutrition programs on this association of interest. We also have the challenge of how best to ascertain diet quality over the individual's lifecourse, meaning, when to measure the diet exposure and how. These are indeed important questions that could possibly be answered using other larger nutrition-oriented surveys that incorporate blood pressure evaluations among their participants.- J.

On a related note, one of our colleagues has indeed explored the role of nutritional food assistance programmes and overnutrition, taking advantage of ongoing national surveys. Perhaps this can shed light on the challenges and opportunities to consider exploring its impact on blood pressure.
