Introduction: Since 2004 the Bioko Island Malaria Control Project (BIMCP) has conducted 3 rounds of indoor residual spraying (86% coverage), reducing malarial parasitemia and anemia among children. The BIMCP rolled out Artemisinin-based Combination Therapy and Intermittent Preventive Treatment (IPT) in 2005. Purpose: This study reports on the coverage of other preventive measures aimed to prevent malaria during pregnancy. Methods: The baseline (2004) household survey collected data from 15 sentinel sites [expanded to 18 in 2005]. The 2004 survey asked women that had been pregnant the previous year about bednet use, chemopropylaxis, and iron supplementation during pregnancy. The 2005 survey, before IPT was rolled out, included a Hemoglobin (Hb) test and a rapid test for malarial parasitemia done to women that were found pregnant at the moment of the visit. Cutoff point to define anemia during pregnancy was Hb<11 g/dL. Results: In 2004 (n= 483), 39.7% of women reported they slept under a bednet every night during their last pregnancy, while 85.8% claimed to have had antenatal care. The 2005 survey (n=220 women) found that 76.6% were anemic, and 18.2% had parasitemia. Parasitemic women had 3 times greater risk of being anemic. While 18.4 % said had taken chemopropylaxis, 41.9% said had taken iron supplements during that pregnancy. Iron pills and antimalarial chemopropylaxis failed to protect pregnant women from anemia (p =0.25 and 0.95, respectively). Implication: The BIMCP monitors IPT coverage and adherence, explores covariates, such as dietary intake of iron, consumption of substances interfering with iron absorption, and hookworm infestation.
