About
The purpose of this study is to compare the efficacy and cost-effectiveness of three alternative strategies for the prevention of malaria during pregnancy in an epidemic-prone area of low transmission in the East African Highlands.
The strategies being compared are:
In addition to the main individually-randomised trial, outcome data was subsequently also gathered on pregnant women whose houses where sprayed with indoor residual insecticides (IRS) as part of a non-randomised district-wide control programme to compare the impact of IRS with the three intervention arms.
Full description
Susceptibility to malaria infection during pregnancy and the severity of clinical manifestation are determined by the level of pre-pregnancy immunity, which depends on intensity and stability of malaria transmission. Most intervention trials to prevent malaria during pregnancy have been conducted in areas of intense transmission. The results of trials conducted in high-transmission areas may not be applicable to low transmission areas, where malaria is less frequent but the risk of spontaneous abortion and stillbirth is very high in women of all parities due to lack of sufficient malaria immunity. Routine chemoprophylaxis is generally not recommended in areas of unstable malaria transmission. However, intermittent treatment with an effective anti-malarial drug may be beneficial, especially during periods of malaria transmission. Little work has been carried out amongst pregnant women living in areas of low and unstable transmission in Africa. No data are available on the cost-effectiveness of malaria control in low transmission settings.
This study will compare the efficacy and cost effectiveness of three preventive strategies for the control of malaria during pregnancy in low-transmission settings. The study is located in Kabale district, a highland area in SW Uganda.
Women attending antenatal care are randomised to receive either:
In addition to the main individually-randomised trial, outcome data was subsequently also gathered on pregnant women whose houses where sprayed with indoor residual insecticides (IRS) as part of a non-randomised district-wide control programme to compare the impact of IRS with the three intervention arms.
The study aims to identify the most effective intervention strategies suited to areas characterised by low and unstable transmission. Research findings should be applicable to other hypoendemic areas of the East African highlands.
