Relationship between the iron status of pregnant women and their newborns

Abstract

Relationship between the iron status of pregnant women and their newborns Relação entre o estado nutricional de ferro de parturientes e seus recémnascidos ABSTRACT OBJECTIVE: To determine the relationship between iron nutritional status of pregnant women and their newborns using a combination of hematological and biochemical parameters for the diagnosis of iron defi ciency. METHODS: A cross-sectional study was conducted in Jundiaí, Southeastern Brazil, in 2000. Venous blood samples collected from 95 pregnant women and from their umbilical cord and used for the determination of complete blood count, serum iron, total iron-binding capacity, serum ferritin, zinc protoporphyrin, and transferrin saturation. Women were classifi ed into three groups: anemic, iron defi cient and non-iron defi cient. Statistical analysis included the Tukey-HSD test, Pearson's correlation coeffi cient and multiple linear regression analysis. RESULTS: Among pregnant women, 19% were anemic (97.9% mildly anemic and 2.1% moderately anemic) and 30.5% were iron defi cient. No signifi cant difference was seen in mean values of any parameter studied between newborns in the three groups (p>0.05). Multiple linear regression analysis showed weak association between neonatal and maternal parameters. CONCLUSIONS: The iron nutritional status of pregnant women with iron defi ciency or mild anemia does not seem to have a signifi cant impact on the iron levels of their children.

“…However, studies have shown that inadequate iron status during pregnancy does not cause inhibition of transfer of iron to the baby, if the mother's nutrition is adequate (23). In another study which is similar to our study, no significant difference was found in babies in terms of iron levels at the time of delivery, although half of the pregnant women had iron deficiency and anemia (24).…”

Prevalência de anemia e deficiência de ferro: relação com índice de massa corporal em gestantes do Centro-Oeste do Brasil

“…2 A carência de ferro ocorre no organismo, de forma gradual e progressiva, até que a anemia se manifeste. 3 As gestantes representam um dos grupos populacionais mais vulneráveis às anemias nutricionais, em função da baixa ingestão durante esse período e aumento da demanda deste mineral. Como conseqüên-cia associa-se a uma maior incidência de abortos, partos prematuros, baixo peso ao nascer e morte perinatal, entre outras.…”
