Available MTC data

The Mexican Teachers’ Cohort (MTC) is a prospective observational study.

Over 15 years, cohort participants have completed self-reported lifestyle questionnaires and attended health assessments as part of the clinical subcohort.

Baseline and follow-up evaluation

In 2006 the MTC began the baseline evaluation in two states: Jalisco and Veracruz. This “feasibility evaluation” phase ended in 2007.

Between 2008 and 2010 the baseline evaluation was expanded to 10 more states: Baja California, Chiapas, Mexico City, Durango, Guanajuato, Hidalgo, Nuevo León, Sonora, Yucatán, and expanded the sample of Jalisco and Veracruz.

In 2011, the first follow-up cycle began for the entire cohort, with a response rate of 83%. The second general evaluation cycle began in 2014 and ends in 2021 with a response of 62%.

In 2022 we have started the third follow-up cycle of the cohort.

Summary of available MTC data by follow-up cycle

The data on risk factors and health conditions have been collected through the baseline and follow-up questionnaires. Below is a summary of the main groups of variables available per evaluation cycle.
