“…At the earliest assessment at one and two months, the iron endowment showed enormous variation. This wide range in the size of the iron endowment has been previously shown by us [4,5,6] and others [7,8,9,10,11,12,13,14,15,16,17,18]. Only a small proportion of that variation was explained by iron status of the mother whereas its bulk remained unexplained.…”

The birth iron endowment provides iron for growth in the first months of life. We describe the iron endowment under conditions of low dietary iron supply. Subjects were infants participating in a trial of Vitamin D supplementation from 1 to 9 months. Infants were exclusively breastfed at enrollment but could receive complementary foods from 4 months but not formula. Plasma ferritin (PF) and transferrin receptor (TfR) were determined at 1, 2, 4, 5.5, 7.5, 9 and 12 months. At 1 month PF ranged from 38 to 752 µg/L and was only weakly related to maternal PF. PF declined subsequently and flattened out at 5.5 months. PF of females was significantly higher than PF of males except at 12 months. TfR increased with age and was inversely correlated with PF. PF and TfR tracked strongly until 9 months. Iron deficiency (PF < 10 µg/L) began to appear at 4 months and increased in frequency until 9 months. Infants with ID were born with low iron endowment. We concluded that the birth iron endowment is highly variable in size and a small endowment places infants at risk of iron deficiency before 6 months. Boys have smaller iron endowments and are at greater risk of iron deficiency than girls.

“…In similar studies, maternal ferritin levels were shown to be in accordance with chord blood ferritin levels of the babies (21,22). 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).…”

“…There are opposite data from developing countries where, among well-nourished maternal population, lower iron status of expecting mothers was associated with a higher birth weight and a longer duration of pregnancy (26). The results of our research show that the anemic mothers’ newborns weighted in average 3048,00 g and were 553,00 g easier compared to the newborns of the control group.…”

Introduction:Sideropenic anemia is a common pregnancy disorder. Depending on severity, maternal anemia can significantly influence morphometric characteristic of placental tissue, pregnancy course and outcome. Objectives: to estimate if maternal anemia a) results with significant placental changes; b) influence on newborn weight, length and vitality.Patients, material and methods:Research included 100 women and their newborns, 50 anemic, and 50 women in the control group. Sixty placentas were collected, placental mass and volume was determined, and blood vessels of terminal villi were stereologically analyzed. Newborns mass and body length, and Apgar scores within 1 and 5 minutes after delivery were recorded.The results:Placentas of anemic pregnant women showed significant increase of terminal villi blood vessels (224,18 vs. 197,00 cm3; p<0,0001), but total placental mass and volume did not differ significantly. Anemic mothers’ newborns were significantly shorter (51,76 vs. 55,54 cm; p<0,0001), smaller body mass (3048,00 vs. 3615,60 g; p<0,0001) and delivered one week early (38,2 vs. 39,2 GW; p<0,0001), but not significantly poorer vitality (p>0,05) comparing with the control group.Conclusion:Sideropenic anemia increase placental maturity, that could be a possible cause of earlier spontaneous delivery among anemic women. The anemic mothers’ newborns are shorter and lower body mass, but not poorer vitality index.
