OBJECTIVE: To describe the prevalence, character and possible aetiology of anaemia in the study region.
DESIGN: A cross-sectional study involving a lifestyle and dietary questionnaire, a clinical examination and an analysis of blood and stool samples.
SETTING: Katima Mulilo antenatal clinic, East Caprivi, Namibia.
SUBJECTS: 171 pregnant women attending the clinic in September 1995.
MAIN OUTCOME MEASURES: Effects on haemoglobin concentration of age, trimester, parity, residential area, sociodemographic factors, malaria, parasites, geophagy, diet, cooking pot used, vitamin and mineral supplementation and malaria prophylaxis.
RESULTS: 41.5% of the women were found to be anaemic (haemoglobin < 11 g/dl) and there was a significant risk of their being iron-deficient (P = 0.01). Three maternal characteristics were found to have a significant effect on a woman's risk of anaemia: urban residence (P < 0.05), geophagy (P < 0.01) and the taking of prophylactic chloroquine (P < 0.05).
CONCLUSION: Mild anaemia affects a large proportion of the pregnant women in East Caprivi; severe anaemia (< 7 g/dl) is not common. The picture is predominantly one of iron deficiency, possibly complicated by concomitant folate deficiency. There is no single easily identifiable cause of this anaemia; it appears to have a multifactorial aetiology. Further studies on the effect of the current malaria prophylaxis programme are warranted.
