Resumen Objetivos: evaluar la prevalencia de anemia gestacional materna y su relación con el peso al nacer. Métodos: estudio observacional longitudinal retrospectivo en una cohorte 370 mujeres gestantes. Se evaluaron variables demográficas clínicas y antropométricas tanto de las madres como de los recién nacidos. Se analizaron los resultados de los índices eritrocitarios maternos y se contrastaron con los datos antropométricos de los neonatos. Resultados: la edad promedio de las gestantes fue de 27±6 años con edad gestacional promedio al momento de la evaluación nutricional de 32±6 semanas, el 56,2% presentaron exceso de peso. La prevalencia de anemia fue de 28,6%. El 47,2% de gestantes con anemia y el 36% de gestantes sin anemia tuvieron neonatos con bajo peso/muy bajo al nacer (p=0,009). De los niños nacidos de madres con anemia ferropénica 20% tuvo bajo peso y 15% muy bajo peso al nacer. El 54,3% de neonatos con desnutrición global o en riesgo de desarrollarla fueron hijos de madres con bajo peso (p=0,046), además a mayor peso materno, menor cantidad de neonatos a término con riesgo de baja talla (p<0,001). Conclusiones: existe relación entre la anemia, el estado nutricional materno y el peso al nacer.

Abstract Objectives: to assess the prevalence of maternal gestational anemia and its association with the birth weight. Methods: retrospective longitudinal observational study in a cohort of 370 pregnant women. Anthropometric, biochemical, ginecobstetric and sociodemographic data of both mothers and newborns were evaluated. The results of maternal erythrocyte indices were analyzed and contrasted with newborns anthropometrical data. Results: the mean age of the pregnant women was 27±6 years, with a mean gestational age of 32±6 weeks at the assessment moment, 56.2% were overweight. The prevalence of anemia was 28.6%. 47.2% women with anemia and 36% women without anemia had low birth weight/very low birth weight newborns (p=0.009). Of the children born to mothers with iron deficiency anemia, 20% had low birth weight and 15% very low birth weight. 54.3% newborns with global undernutrition or at risk of developing it were born to women with underweight(p=0.046), in addition, the higher the maternal weight, the lower the number of term newborns with risk of short height (p<0.001). Conclusions: there is relationship between the anemia, the maternal nutritional status and the birth weight.
