Iron Deficiency and Anaemia in Pregnant Women in Malaysia - Still a Significant and Challenging Health Problem

Nils Milman

Background: Iron deficiency (ID) is the most frequent cause of anaemia (IDA) in women of reproductive age and pregnant women. Recommended cut-off value for anaemia in women of reproductive age is haemoglobin (Hb) <12.0 g/dL and in pregnancy Hb <11.0 g/dL. Serum ferritin <15-20 μg/L is consistent with ID; Hb below cut-off values and ferritin <12-15 μg/L is consistent with IDA. Methods: Literature survey on publications and guidelines on the frequency of ID and IDA in Malaysia compared with Western countries. Results: Prevalence of anaemia in women of reproductive age is ~30% and in pregnant women ~40%. With advancing pregnancy the frequency of anaemia increases, due to deficiency of iron and hematinic vitamins (folate, vitamin B12). Iron demands in pregnancy cannot be fulfilled by dietary iron intake but require oral iron supplementation. If the mother has IDA, the newborn has a high risk of ID and IDA. ID and IDA have multiple negative effects in both infants and adults. Oral iron prophylaxis should start at 10-12 weeks gestation. Among pregnant women in Malaysia 80-90%, have low iron status and 38-42% develop anaemia. Consequently, the prophylactic oral iron dose should be 100 mg ferrous iron/day. IDA is treated with oral ferrous iron 180-200 mg/day and Hb should be checked after 2-3 weeks. If there is no increase in Hb, due to poor compliance and/or impaired iron absorption, or the anaemia is severe (Hb <8.0 g/dL) treatment with intravenous iron is indicated. Conclusions: In Malaysia, anaemia in pregnant women still constitute a major and challenging health problem. We are aware of the causes for anaemia and we know the solutions, so efforts should focus on better implementation of early oral iron and vitamin prophylaxis, early diagnosis of anaemia, and on increasing the low compliance of the women to the prophylaxis programs.
