INTRODUCTION Anaemia is the commonest pregnancy complication worldwide. Anaemia in pregnancy is a leading cause of maternal and perinatal morbidity and mortality especially in developing countries. It is a medical condition that is usually preventable through public health interventions, which are often feasible and cost effective. In order to strengthen the understanding of the disease as well as the planning for the management of patients, this study sought to ascertain the prevalence of anaemia in pregnancy as well as the outcome of singleton pregnancies that are complicated by maternal anaemia at the University of Port Harcourt Teaching Hospital, in South-South Nigeria. OBJECTIVE The overall goal of this study was to determine the prevalence of anaemia in pregnancy and the outcome of pregnancy complicated by maternal anaemia with regards to gestational age at delivery, fetal birth weight and apgar scores amongst women with singleton pregnancies attending antenatal clinic at the University of Port Harcourt Teaching Hospital, South – South Nigeria. METHODOLOGY The study was a prospective survey of 430 pregnant women attending the antenatal clinic at the University of Port Harcourt Teaching Hospital. Participants were consecutive patients with singleton pregnancies booking for antenatal care who gave consent to be recruited for the study. Participants were enrolled at their booking antenatal visit and monitored through pregnancy till delivery. Haemoglobin concentration was used to assess the level of anaemia while Haemoglobin genotype, blood film for red cell morphology and presence of malaria parasites, Urinalysis and Urine Microscopy/culture were used to assess clinical correlates of anaemia. Proforma designed for the purpose was used to obtain demographic information as well as outcome measures. Statistical analysis of results was done using EPI-Info software package
