Due to the high prevalence of overweight and obesity in adolescents in our country, different studies have been done from the perspective of risk factors (type of locality of residence, welfare conditions, family history of obesity, physical activity, time in front of the screen), with this study we propose to evaluate the nutritional status and socioeconomic conditions in adolescents and compare it with the nutritional status presented at preschool age in a population of rural localities of the State of Mexico. A retrospective cross-sectional observational study was carried out, including 515 children from 27 localities distributed in three municipalities of the State of Mexico from a sample universe of 1740 preschoolers, of whom at least two anthropometric data of weight and height measured between the years 2002 - 2009 were available. For the final measurements, we worked with adolescents between 12 and 16 years of age, who had fathers, mothers or guardians present and obtained the following data: identification, housing characteristics, resources for family nutrition, parents' general data, postnatal information, etc.
