Title: A Prospective Study of Hemoglobin Status, Micronutrient Serum Levels and Nutrient Intake of Iranian Pregnant Women during Pregnancy and Their Relation to Birth Weight of the Neonates
Author: Moghaddam Tabrizi, Fatemeh; Radfar, Farahnaz
Abstract: A prospective study was conducted in Iran to investigate the hemoglobin status, micronutrient serum levels and nutrient intake of Iranian pregnant women and their relation to birth weight. Nutrient intake was computed based on 24 hour recall method. During the three trimesters of pregnancy, blood specimens were collected from healthy pregnant women aged 16-40 years. Maternal serum levels of micronutrients were determined by an inductively couple plasma mass spectrometer (ICP/MS) and haemoglobin was assessed by Cyanomethemoglobin. The mean age of studied pregnant women was 26 ± 5years, and the mean birth weight of neonates was 3.3 ± 0.4 kg. The 11% of neonates were considered as low birth weight. The results showed that majority (41%) of pregnant women were in age group 26-36 years. The mean hemoglobin during the second trimester was significantly lower than the mean hemoglobin in the first and the third trimesters of pregnancy. The majority of the anemic women belonged to mild category during pregnancy. Regarding micronutrients, results indicate that iron levels decreased significantly from first to second trimester and significantly increased in third trimester. Serum zinc levels of subjects significantly decreased gradually during the first, second and third trimester. Serum copper levels increased significantly with increasing the gestational period. Calcium and magnesium serum levels during three trimesters were constant. Maternal hemoglobin levels, calcium, iron and zinc serum levels were associated with birth weight of neonates. Energy, protein, calcium, zinc and iron intakes in the third trimester were significantly associated with birth weight of neonates. The findings showed that calcium, protein, iron and energy intake of pregnant women could be considered as primary ″predictor factors″ for birth weight of neonates.
