3. Community based distribution delivery approach (CBD). In addition to passive delivery at health centres, the pregnant women will be reached by traditional birth attendants (TBAs) or representatives of village women's associations (RWAs). Each approach will be implemented in a zone constituted by the catchment area of a number of health centres to achieve the required sample size. The zones will be randomly assigned to a delivery approach. The main outcomes to be measured are: a) the coverage of IPT, b) compliance, c) infection prevalence, d) Hb level, e) difficulties and constraints of each approach, f) the acceptability to population and health staff and g) the performance of each approach to deliver IPT /SP. to be able to identify a significant increase in coverage of 10%, each group should be composed of n = 3841 pregnant women.
