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.
