 Pregnant women are at an increased risk for malaria infection and disease. Maternal anaemia, low birth weight and prematurity are the most frequent adverse effects of the infection. The current WHO recommendation consists on the provision of insecticide treated nets ITNs and intermittent preventive treatment IPT. Results from a recentn trial of ITNs have shown a significant reduction in maternal anaemia, parasitaemia and low birth weight prevalence in women sleeping under impregnated nets. However, scarce information exists on the relative efficacy of IPT and ITNs to reduce the deleterious effects of malaria infection during pregnancy when given at the same time. This information is of relevance to guide national malaria control programmes.
