Prevalence of anaemia in pregnant women during the last trimester: consequense for birth weight
European Review for Medical and Pharmacological Sciences
Iron deficiency continues to be one of the most prevalent single-nutrient deficiencies in the world. The current study aimed to estimate the prevalence of iron deficiency anemia (IDA) among pregnant women who attend Antenatal Care Centers in Sidi Bel Abbes, Algeria. The effect of anaemia on infant birth weight was also examined. The study was conducted during the period March-Mai, 2010 and the sample consisted of 207 pregnant women (in the third trimesters) in the age group (17-41) years. The
... bjects were not taking iron, folate or vitamin B12 supplements at the time of the study. Blood samples were collected from each pregnant woman and a questionnaire was completed at the time of blood collection. A series of determinations was conducted to determine hemoglobin concentration (Hb); packed cell volume (PCV); corpuscular hemoglobin concentration (MCHC), corpuscular volume (MCV). The effect of anemia on the weight of new born babies was examined by calculating the correlation coefficient of birth weight and hematological indexes. The overall prevalence of anemia was found to be 46.86%. According to the severity anemia was 36.08% mild, 49.48% moderate and 14.43% severe anemia. The mean values (+/- SD) of haematological indexes were as follows: Hb 9.00 +/- 1.57 g/dl; PCV 27 +/- 5.37%; mean corpuscular haemoglobin concentration (MCHC) 33.75 +/- 2.69 g/dl and mean corpuscular volume (MCV) 75.7 +/- 10.4 fl. The results have shown that 46.39% of the subjects had MCV values less than standard value of 75 fl suggesting a microcytic anemia. The mean haemoglobin concentration was 9 +/- 1.57 g/dl while the mean birth weight was 3201.54 +/- 566.71 g. There was a not significant correlation between the Hb level and the birth weight of the infants (r = 0.28, p > 0.05). The prevalence of low birth weight was 9.2%. There was no statistically significant haemoglobin concentration /foetal birth weight difference among the various hemoglobin concentration (Chi square test = 0.34, p > 0.05). Anemia had no significant obstetric adverse effects in our pregnant population (Fischer test = 0.06, p > 0.05). There was no statistically significant difference in mean birth weight among the various haemoglobin groups suggesting that other parameters may play important roles in influencing the birth weight than the maternal haemoglobin concentration.
