Hemoglobin Concentration Level during Pregnancy and Its Association with Birth Weight

摘要

Introduction: The study aimed to assess the relationship between early pregnancy Hemoglobin (Hb) concentration and weight gain status in pregnant women and birth weight. Material and Methods: This is a retrospective study that was carried out on the 1994 under-five-year children. Among 118 villages in Gorgan and Aq-Qala districts, 20 villages were chosen by random sampling. Birth weights, birth stature, means of Hb in early pregnancy and maternal weight gain during pregnancy have been recorded by health care file available from Primary Health Care System. Hb concentration divided in three classifications: Low (Anemia) =Hb=12.5 g/dl (11). SPSS 16.0 software was used for statistical data analysis. Results: The mean and standard deviation of maternal serum Hb, birth weight and weight gain during pregnancy were 12.0±1.1g/dl, 3.3±0.5 kg, and 10.5±4.1kg, respectively. Anemia (HbHb g/dl). Conclusion: Low Hb concentration during pregnancy is a main health problem in rural area in the north of Iran. The positive association between serum Hb concentration and weight gain was seen in pregnancy, while it was not significant association with birth weight.
