National Health and Nutrition Survey 2018-19: Methodology and perspectives

Abstract

Objective. Describe the methodological design of the National Health and Nutrition Survey 2018-19 (Ensanut 2018-19). Materials and methods. Ensanut 2018-19 is a probabilistic household survey. The following design elements are described: survey scope, sampling procedure, measurement procedure, inference procedure, and logistics organization. Results. 44 069 full housing interviews and 82 490 full interviews of individuals were obtained. The home response rate was 87%. The response rate for individuals was 98%. Conclusions. The probabilistic design of the survey allows to create valid statistical inferences on parameters of public health interest at the national level and for all 32 states. In addition, some of the results are comparable with Ensanut 2012 in order to identify potential changes in the health and nutrition status of the Mexican population, so that health policies can be adjusted if necessary.
