Submuestra para el análisis de enfermedades crónicas con biomarcadores, Encuesta Nacional de Salud y Nutrición 2016

Abstract

Objective.To describe the adult subsample for the analysis of biomarkers of chronic diseases, as well as the sample sizes (n) and representativity of the Encuesta Nacional de Salud y Nutrición (Ensanut) 2016. Materials and methods. An adult subsample with national representativity was calculated to obtain blood, serum and urine samples. The prevalence of variables of interest was compared for each subsample. Results. The n for at least one serum biomarker and urine samples were 4 000 and 3 782, respectively. The n varied depending on the grouping of biomarkers and fasting time selection. No differences were observed in the distribution of variables between the whole sample, urine and blood biomarkers samples. Conclusion.The weighted subsamples of urine, serum and blood biomarkers are comparable to the weighted sample of adults in the survey.The data of the subsample will allow to monitor the distribution of chronic diseases in Mexico, including altered function of liver and kidney, and sodium intake.
