Intermittent Preventive Treatment of Malaria in Pregnancy Coverage Estimates from Population-based Surveys: Reliability of Women's Recall Among Women with ANC Cards

Large household surveys performed to estimate coverage rates for various health interventions, including intermittent preventive treatment, depend on recall. Many studies question the validity of recalled data. Regarding vaccine coverage rates, it is standard practice to validate responses using medical history cards. To validate the coverage rates of intermittent preventive treatment during pregnancy reported by large household surveys, recalled coverage rates were compared with antenatal care card data in Benin, Ghana, Malawi, and Tanzania. The results indicated that recall was comparable to the coverage rates provided indicated by the antenatal care cards. These findings suggest that intermittent preventive treatment coverage rates reported by large household surveys performed using recalled data are valid.
