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).
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 under-estimated in a range of 2% to 55.5%.
We documented the relevance of the application of NRFs for adequate estimation of the prevalence of inadequate intake of selected nutrients in population studies.
评估墨西哥人群中选定营养素的常规摄入量和不足率，并评估营养素留存因子（NRF）对这些估计值可能产生的潜在影响。此外，还记录了 2016 年全国健康和营养调查（ENSANUT MC 2016）中间日 24 小时分析中使用的方法。
使用和不使用 NRF 对 ENSANUT MC 2016 的饮食信息进行了分析。
结果。在所有年龄组中，评估的大多数营养素都显示出相关的不足率超过 10%。同样，我们记录到，如果不应用 NRF，估计的摄入量和不足率会在 2%至 55.5%的范围内显著低估。
我们记录了应用 NRF 对人群研究中选定营养素不足摄入的流行率进行适当估计的重要性。
