Maternal Anaemia in Pregnancy: A Significantly Greater Risk Factor for Anaemia in Australian Aboriginal Children than Low Birth Weight or Prematurity

Use of antianemics in prenatal care: A population cohort from a capital city in the North region of Brazil

Anemia during pregnancy is a significant risk factor for adverse maternal and fetal outcomes, including preterm birth, low birth weight, and maternal mortality. In Brazil, anemia prevention and treatment programs are available, but regional variations in prevalence and factors associated with antianemic drug use remain understudied. The objective was to identify the prevalence of gestational anemia and the factors associated with the use of antianemic drugs during pregnancy in a cross-sectional population-based study carried out in Rio Branco, AC. To do so, we planned a cross-sectional, population-based study with a total of 1190 postpartum women who gave birth between April 6 and July 10, 2015, were interviewed about demographic, socioeconomic, reproductive, and prenatal care factors. The prevalence of anemia during pregnancy was found to be 13.8 %, with 93.2 % of women using antianemic drugs, such as ferrous sulfate and folic acid. Factors positively associated with antianemic drug use were higher education (elementary school II RCajust = 2.46; 95 %, CI: 1.01-6.13; high school RCajust = 2.61; 95 %, CI: 1.11-6.12), primiparity (ACadjust = 1.69; 95 %, CI: 0.98-3.74), 6 to 8 prenatal consultations (ACjust = 2.16; 95, CI%: 1.15-4.05), and planned pregnancy (ARjust = 1.94; 95 %, CI: 1.05-3.74). Food security during pregnancy was inversely associated. These findings suggest that while anemia prevention and treatment programs exist, more targeted strategies are needed, particularly for women with lower socioeconomic status, to improve maternal and fetal health outcomes.

The interplay between maternal-infant anemia and iron deficiency

Iron deficiency anemia in pregnancy is a major public health problem known to cause maternal morbidity and adverse birth outcomes, and it may also have lasting consequences on infant development. However, the impact of the maternal hematological environment on fetal and infant hemoglobin and iron stores in the first year of life remains unclear. This review of the epidemiological evidence found that severe maternal iron deficiency anemia in pregnancy is associated with lower ferritin, and to a lesser degree hemoglobin levels, in infants at birth. Emerging data also suggests that severe anemia in pregnancy increases the risk of iron deficiency and anemia in infants 6-12 months of age, although longitudinal studies are limited. Effective anemia prevention in pregnancy, such as iron supplementation, could reduce the risk of infant anemia and iron deficiency during the first year of life; however, more evidence is needed to determine the functional impact of iron supplementation in pregnancy on infant hematological indices.

Dietary association of iron deficiency anemia and related pregnancy outcomes

Iron deficiency anemia (IDA) is a common public health occurrence of pregnancy which is particularly prevalent in developing countries like Pakistan. During this critical period, the deficiency of iron is very common as the iron requirements are greatly enhanced. IDA during pregnancy is associated with intrauterine growth retardation, premature birth, low birthweight, increased labor time, higher risk of infection, elevated maternal and prenatal mortality, muscle dysfunction, and low physical capacity. The present study was aimed to check the prevalence, effect of diet on IDA and its association with the pregnancy outcome, that is, birthweight. Five different public sector hospitals of Rawalpindi and Islamabad were analyzed. A sample size of 500 pregnant females of third trimester was observed which were then followed after delivery from September 2020 to January 2021. A well-designed questionnaire was developed where different demographic factors, dietary recalls, biomarkers, and other determinants were obtained. The data from the questionnaires were later coded for the purpose of analysis in the statistical package (SPSS) using chi-square test. Our study indicated that IDA is a moderate public health problem among pregnant women in twin cities and more than half of study subjects have depleted iron stores. Approximately 63% of the subjects were having iron deficiency and 24.8% were facing severe iron deficiency anemia. Only 12% of the subjects were considered as normal. The high prevalence of anemia in our subjects was probably due to low iron intake and poor dietary habits. The results of the study may not be generalizable due to time constraints and other factors. Maternal anemia still remains a major public health concern that requires more attention especially in developing and underdeveloping countries.
