HIV as an additional risk factors for anaemia in pregnancy: evidence from primary care level in Ibadan, Southwestern Nigeria.

Anaemia in pregnancy has serious consequences including maternal morbidity and impairment of infant cognitive development. Several authors have however reported inconsistent findings on risk factors for anaemia in pregnancy. This study was carried out to determine risk factors for anaemia in pregnancy among women at primary care level and document the contribution of HIV/AIDS to anaemia in pregnancy in low risk pregnant women at primary care level. A prospective study carried out among pregnant women attending the booking clinics of primary health care centres in Ibadan, Nigeria. HIV positive and HIV negative mothers were followed throughout pregnancy till delivery of their babies. History of use of iron, folate, Vitamin B complex and daraprim were obtained. Haemoglobin, malaria parasitaemia, and HIV serostatus were determined. Use of iron (P < 0.006), folate (P = 0.032), vitamin B complex (P = 0.001) and treatment for malaria (P = 0.05) significantly reduced the risk for anaemia in pregnancy. Malaria parasitaemia (P = 0.0001) significantly increased the risk of anaemia. However, use of daraprim and HIV seropositivity increased the risk of anaemia in pregnancy but not significantly. In a logistic regression analysis, iron (P = 0.001) and folate supplementation (P = 0.015) significantly protected against anaemia in pregnancy while malaria parasitaemia (P = 0.006) and HIV seropositivity (P = 0.015) were significant adverse risk factors. HIV is an additional risk factor for anaemia in pregnancy. Voluntary counseling and testing of pregnant women for HIV is therefore also indicated at primary care level to detect asymptomatic anaemia in pregnancy that may be due to HIV.
