Objective:

To estimate the usual intake and the prevalence of inadequacy of selected nutrients in the Mexican population and the potential effect that the nutrient retention factors (NRF) could have on these estimates. Likewise, document the methodology used in the analysis of the 24 hours of the mid-way National Health and Nutrition Survey 2016 (Ensanut MC 2016).

Materials and methods:

Dietary information from the Ensanut MC 2016 was analyzed with and without the use of NRFs.

Results:

Most nutrients evaluated showed a relevant inadequacy prevalence above 10% in all age groups. Likewise, we documented that, when NRFs were not applied, estimated intakes and prevalence were significantly underestimated in a range of 2% to 55.5%.

Conclusions:

We documented the relevance of the application of NRFs for adequate estimation of the prevalence of inadequate intake of selected nutrients in population studies.
