Prevalence and risk factors for anaemia in pregnancy in South Southern Nigeria.

The aim of this study was to ascertain the prevalence of anaemia in pregnancy in South Southern Nigeria, and to identify an 'at-risk' group for targeted intervention. Antenatal women were screened for anaemia for 1 year (October 2000-September 2001) at the booking clinics of our three government hospitals in Kwale zone. Univariate and multivariate logistic regressions of risk factors for anaemia ([Hb] < 11 g/dL) and severe anaemia ([Hb] < 7.0 g/dL) were carried out. The prevalence of overall anaemia and severe anaemia was found to be 56.1% and 6.7%, respectively. Independent risk factors for anaemia and severe anaemia were primigravidity, booking in late pregnancy and wet season. We conclude that anaemia remains a common problem in our population, and additional intervention for the 'at-risk' group is recommended.
