ABSTRACT

Objective. To describe the methodology of the 2025 National Health and Nutrition Survey (Ensanut Continua 2025), including its sampling design, operationalization, specific subsamples, and its utility for informing public policy decisions. Materials and methods. A probabilistic, multi-stage, stratified, cluster sampling design was employed. The general sample will include 11 940 households, aiming to obtain 9 000 complete household interviews and approximately 16 462 individual health interviews. Additionally, individuals affiliated with the Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado health system residing in the selected households will be interviewed, with an expected 1 464 complete health interviews. The Casa por Casa (House-to-House) Health Component will enable 6 087 health interviews with all adults aged 55 and older. Data collection will take place from August to December 2025, using electronic questionnaires, standardized measurements, and blood sample collection. Results. The survey is expected to generate updated estimates on key indicators of health, nutrition, service utilization, food access, and environmental conditions, as well as to analyze trends between 2021 and 2025 and characterize inequalities by age, sex, region, and type of locality. Conclusions. Ensanut 2025 strengthens an evidencebased health and nutrition surveillance system with a lifecourse approach and operational relevance. Its robust design will enhance the planning, implementation, and evaluation of public policies.
