Prevalencias de estado de nutrición en recién nacidos mexicanos por peso y longitud al nacimiento: un análisis de los certificados de nacimiento del Sinac.

Objective. To describe the national by federal entity prevalence of the nutritional status of weight and length at birth. Materials and methods. Cross-sectional descriptive study. Data from 1 907 341 alive newborns in 2017, registered in the Subsistema de Información sobre Nacimientos (Sinac), were analyzed. The percentiles for weight and length were estimated in the INTERGROWTH-21st platform. Results. The prevalence of small gestational age (SGA) and insufficient length (IL) was 7.4 and 4.8%, respectively. Differences in the prevalence of IL, SGA and large for the gestational age (LGA) by sex were recorded (p <0.01). The entities with the highest prevalence of SGA were Estado de México and Yucatán (10.4%); Sonora (15.3%) and Baja California Sur (16.8%) of LGA. Conclusion. Sizing the nutritional status at birth allows the identification of entities that require targeted actions to reduce the risks associated with malnutrition. [ABSTRACT FROM AUTHOR]
