RESUMEN
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 cm(3); 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.
