A retrospective study of the prevalence of anaemia in pregnancy at booking in Niger Delta, Nigeria.

We reviewed the records of antenatal clinic attendees over a period of 9 years to determine the prevalence of anaemia at booking. The laboratory records of 8751 out of a total of 37,506 pregnant women who booked for antenatal care between 2004 and 2013 at the BMSH were reviewed. The effects of maternal age, educational status, parity, gestational age, haemoglobin genotype and infections on the prevalence of anaemia were investigated. The prevalence of anaemia at booking was 69.6%, most of whom had moderate anaemia. Anaemia was significantly prevalent in the 10-19 year age group, and in women with secondary education, in their 2nd trimester and with SS genotype. Anaemia also increased with gestational age, this however was not statistically significant. There was no statistical difference between those who are human immunodeficiency virus (HIV) positive and had anaemia and those who are HIV negative who also had anaemia. This study shows that anaemia in pregnant women is still unacceptably high considering the consequences and despite interventions on the ground to reduce prevalence. There is a need to review the intervention measures with emphasis on programmes that would increase awareness among pregnant women and the general public.
