BACKGROUND: HIV /AIDS have been described as a risk factor for anaemia in pregnancy. Anemia is associated with a faster rate of disease progression and poor survival in patients with HIV. Anaemia has also been linked with early post natal death in infants of HIV Positive pregnant women. It is therefore pertinent to document the prevalence and determinants of anemia in HIV positive pregnant women. STUDY DESIGN, SETTING AND SUBJECT A cross sectional study was carried out among HIV positive pregnant women as the study group and HIV negative pregnant women as controlled group at the antenatal clinic of the Jos University Teaching Hospital (JUTH), Jos MAIN OUTCOME MEASURES The prevalence of anaemia in the experimental group was determined. The possible determinants of anemia were ascertained and the relationship between variables determined using methods of linear regression and chi square test.
