Anemia materna y peso al nacer en productos de embarazos a término

Abstract

Aim: To link maternal anemia and birth weight (BW) in women with term pregnancies present to emergency obstetric at the Maternity "Dr. Armando Castillo Plaza", in Maracaibo, Venezuela. Methods: A correlational research, with non-experimental and transactional design, where valued a sample of 200 pregnant women in active phase of labor, who are determined hemoglobin (Hb), hematocrit (Hct), and hematimetric indexes values. Results: The values of Hb and Hct in anemic ranged from 8.4 ± 1 g/dl and 11.6 ± 0.64 g/dl, whereas the Hct was 28.8 ± 3.3[%] and 38.9 ± 2.2[%], in patients with and without anemia, respectively. The hematimetric indexes showed normal reference values in both groups. The BW in newborn of anemic mothers was decreased by 12.39[%] (-420 g) when compared to the weights of infants of mother without anemia (2.970 ± 0.43 g vs. 3.390 ± 0.32 g; p<0.0001). LBW was more common in the group of anemic mothers, who showed an increased risk, although not significant (15[%] vs. 10[%]; OR 95[%]CI 1.588 [[]0,676 - 3,728]; p>0.05). Was demonstrated a directly proportional and significant relationship between Hb values and BW(r=0.439; p<0.0001). Conclusion: Exist a direct proportional and significant relationship between the PAN and the Hb; however, while anemic pregnant women presented more frequently LBW, this difference was not significant.
