Prevalence and factors associated with anaemia in pregnant women in Cascades Region of Burkina Faso in 2012

INTRODUCTION: anaemia in pregnancy is a public health concern in Burkina Faso. This study aims at identifying the factors associated with the prevalence of anaemia in pregnant women at a regional level in Burkina Faso. METHODS: we conducted a cross-sectional study in the region called “Cascades”, located at the Western part of Burkina Faso. The study population included all pregnant women who attended antenatal care clinics in all public peripheral health facilities (districts) between May and June 2012 and agreed to participate in the study. They provided blood sample from which we measured the haemoglobin concentration using the Hemocue® system. The factors associated with anaemia in the study population were identified through multiple logistic regressions. RESULTS: the prevalence (95% CI) of anaemia in pregnancy in the Cascades region was 58.9% (56.6% - 61.2%). Anaemia in pregnancy was more common in district of Banfora (OR = 1.40; 95% CI: 1.07-1.83), among housewives (OR = 2.96; 95% CI: 1.10-8.0), in the Mossi ethnic group (OR = 1.39; 95% CI: 1.04-1.85) and among the wives of farmers and artisans (OR = 2.55; 95% CI: 1.59-4.07). Anaemia in pregnancy was less frequent among women who drank local beer (OR = 0.68; 95% CI: 0.49-0.94). CONCLUSION: the prevalence of anaemia in pregnancy is high in Burkina Faso. Improving women's income level may contribute to reduce it. Further studies are needed to elucidate the link between the consumption of local beer, the local diet practices and anaemia in pregnant women.
