title: [Determination of prevalence and etiology of anemia during pregnancy in southern Benin, in conjunction with revision of national management policy].
abstract: BACKGROUND
  Anemia during pregnancy is a serious public health problem. Control requires identification of the underlying etiology. The objective of this study carried out in conjunction with revision of the national policy for the protection of pregnant women in Benin was to determine the prevalence and etiology of anemia.
  
  
  METHODS
  From October 2006 to April 2007, 300 pregnant women were examined at two maternities in Ouidah, Benin. Sociodemographic and environmental characteristics, dietary data, behavioral practices, and history of malaria infection during pregnancy were collected. Blood and stool samples were tested for the presence of malaria parasites and intestinal worms respectively. Hemoglobin and ferritinemia levels were also determined.
  
  
  RESULTS
  The prevalence of anemia (Hb < 11 g/dL) was 65.7% while that of malaria and intestinal worms was 4.3% and 8% respectively. Iron deficiency was not found. A borderline significant correlation was found between helminthiasis and anemia. No correlation was found between anemia and malaria. These findings indicate that kits progressively introduced by the health system during the study period provided relatively effective care.
  
  
  CONCLUSIONS
  This study demonstrates a high prevalence of moderate anemia during pregnancy and suggests that it is mainly due to intestinal helminthiasis. These findings underline the importance of preventive antihelminthic treatment during pregnancy.
