Cohort Study of Metabolic Disease and Hypertension

5. maj 2026 opdateret af: Coordinación de Investigación en Salud, Mexico

Metabolic Disease and Hypertension in Adults: A Prospective Cohort Study (Phase One)

The goal of this observational study is to learn how type 2 diabetes and high blood pressure develop over time in adults in Mexico. The study will include men and women between 18 and 65 years of age who do not have a previous diagnosis of these conditions.

The main questions this study aims to answer are:

What factors increase the risk of developing type 2 diabetes? What factors increase the risk of developing high blood pressure?

Participants will not receive any experimental treatment. Researchers will observe their health as part of their regular medical care.

Participants will:

Attend an initial visit that includes physical measurements, blood tests, and questionnaires about their health, lifestyle, and environment Perform a simple walking test to measure physical fitness Return once a year for follow-up visits over a period of five years

During the study, researchers will monitor participants to identify new cases of type 2 diabetes and high blood pressure.

The results of this study may help improve prevention strategies and support public health programs aimed at reducing chronic diseases in Mexico.

Detaljeret beskrivelse

This prospective dynamic cohort study includes repeated annual measurements to evaluate temporal changes in cardiometabolic exposures and their relationship with incident outcomes.

Data will be collected using standardized procedures and electronic case report forms captured via a tablet-based system. Information will be recorded in the digital platform of the MIDO ecosystem, developed by the Carlos Slim Health Institute, and subsequently safeguarded by the Mexican Social Security Institute (IMSS) in accordance with applicable regulations on research and personal data protection. The database will be preserved for at least 10 years, ensuring confidentiality and appropriate use of the information.

Measurements include anthropometric assessments, blood pressure, biochemical testing, and structured instruments for lifestyle, physical fitness, and social and environmental determinants. Physical fitness will be assessed using the six-minute walk test.

Data management will include internal consistency checks, identification of outliers, and assessment of missing data. When appropriate, imputation methods and sensitivity analyses will be applied.

Participants will be followed longitudinally, allowing evaluation of changes in exposures and their association with outcomes. Statistical analysis will include multivariable models and dimensionality reduction techniques, such as principal component analysis, to identify patterns among risk factors.

Studiebefolkning

Adults aged 18 to 65 years receiving care at primary health care units of the Mexican Social Security Institute (IMSS) and IMSS-Bienestar in Mexico. Participants do not have a prior diagnosis of type 2 diabetes mellitus or hypertension at baseline and represent a population at risk for developing these conditions. The study includes individuals with varying cardiometabolic profiles, lifestyle behaviors, physical fitness levels, and social and environmental exposures.

Intervention / Behandling
General population cohort
This cohort includes adults aged 18 to 65 years without a prior diagnosis of type 2 diabetes mellitus or hypertension, who are followed over time to evaluate the development of these conditions and their association with cardiometabolic, lifestyle, physical fitness, and social and environmental factors.
Andet: Observational Study
Participants are observed over time without receiving any experimental intervention. Data are collected as part of routine clinical assessments and scheduled follow-up visits.
