Mexico Launches 2025 Health, Nutrition Survey

Mexico’s Ministry of Health (SSA) has begun fieldwork for the 2025 National Health and Nutrition Survey (ENSANUT), a study designed to update key data on health and nutrition across the country. The survey, led by the National Institute of Public Health (INSP), will be conducted from August to December and cover 12,000 households nationwide.

“The results of ENSANUT are a critical input to measure progress and define priorities that strengthen Mexico’s public health agenda,” says SSA in a statement.

The survey’s main purpose is to provide a quantitative description of the health and nutrition status of the Mexican population in 2025. It also seeks to generate state-level estimates for all 32 federal entities by the end of the year and to include a special oversample of people enrolled in the ISSSTE social security system. This group will be surveyed with an additional set of questionnaires.

Households selected for participation are asked to answer questions during in-home interviews and, when applicable, to allow anthropometric measurements such as weight and height, as well as the collection of biological samples. Officials emphasized that the information gathered is confidential and has no consequences for respondents.

Survey brigades will also gather data on specific programs and health areas. The 2025 edition includes questions about the government’s “Salud Casa por Casa” program and, for the first time, will collect information on visual health across the population.

The Ministry of Health and INSP are calling on the public to collaborate with the teams. Participation, they say, is essential to obtain reliable data that can guide public health decisions. The ENSANUT results will serve as a basis for monitoring health trends, shaping nutrition and prevention policies, and allocating resources more effectively across Mexico’s health system.

To enhance transparency, the INSP publishes weekly updates on the survey teams’ locations through its institutional social media accounts. Citizens can consult these updates to identify when brigades will be present in their communities.

By updating national health and nutrition data every year, ENSANUT provides policymakers with evidence to design interventions and monitor outcomes in areas such as obesity, chronic disease, child development, and preventive care. The 2025 survey continues that role with the inclusion of new dimensions of health information.
