ABSTRACT

Resumen: Objetivo: Cuantificar los cambios de sobrepeso y obesidad (SO+O) y determinar su asociación con características sociodemográficas en escolares mexicanos de primarias públicas durante 2015 y 2018. Material y métodos: Estudio transversal comparativo. Se analizaron 6.5 millones de alumnos de 59 724 escuelas. La información deriva del Registro Nacional de Peso y Talla (RNPT) en cuatro periodos escolares, de 2015 a 2019, para niños de 6 a 12 años. Se estimaron razones de momios (RM) y prevalencias ajustadas mediante regresión logística ordinal generalizada. Resultados: Las RM fueron positivas para SO+O y para obesidad en el sexo masculino, ámbito urbano y baja marginación (p<0.001). La mayor prevalencia ajustada tanto para sobrepeso como para obesidad se reportó en 2016 (p<0.001). La región Sur manifestó ascensos constantes y significativos para obesidad durante cuatro periodos. Conclusión: El RNPT permite detectar diversas características de riesgo actual para el desarrollo de SO+O en escuelas primarias del país.


Abstract: Objective: To quantify changes in overweight and obesity and determine their association with sociodemographic characteristics in Mexican schoolchildren from public schools between 2015 and 2018. Materials and methods: Cross-sectional comparative study. The data of children between 6 an 12 years old was obtained from the National Register of Weight and Height (RNPT) during four years: 2015 trough 2019. Odds ratios (OR) and adjusted prevalences were estimated using generalized ordinal logistic regression. Results: A rough total of 6.5 million of children from 59 724 schools were studied. The OR's were positive for overweight and obesity (OW+OB) in male gender, urban locality and low marginalization (p<0.001). The greater adjusted probability of overweight and obesity found in 2016 (p<0.001). The country's south region shown constant and significative increases in obesity probabilities. Conclusion: The RNPT allows a real time detection of the various risk characteristics involved in overweight and obesity development in the country elementary schools.
