The aguascalientes longitudinal study of child development: Baseline and first results

This paper introduces the readership to the Aguascalientes Longitudinal Study of Child Development (EDNA) and presents the first descriptive results. EDNA is a prospective, multi-thematic, and multidisciplinary longitudinal study of the cohort of children that began first grade in August 2016 in the public schools of the state of Aguascalientes, Mexico. The sample contains a group of 1,000 pupils from 100 public schools who are representative of the study population. Recontact is planned to occur every two years for at least three waves. The baseline survey was conducted between 2017 and 2018. The study consists of an interview with the primary carer of the randomly chosen pupil, an interview with the pupil at school and an interview with the pupil’s teacher at the premises of the Institute of Education of Aguascalientes. EDNA aims to identify and contribute to solving the problems faced by Mexican children to achieve healthy physical and intellectual development on their way to adult life.
