RESUMEN
Background: Malaria is a life-threatening disease caused by parasites that are transmitted to people through bites of infected female Anopheles mosquitoes. Africa is the home to over 90% of malaria burden when compared to other regions of the world. The region is estimated to have a dominance of 94% of maternal deaths occurring in the world. The purpose of this study was to identify factors associated with the uptake of IPTp-SP among pregnant women in Tanzania. Method: The study used data from the 2015-16 Tanzania Demographic and Health Survey and Malaria Indicators Survey (2015-16 TDHS-MIS). A total of 6,885 women of active reproductive age from 15 to 49 were included in the analysis. Both univariate and multiple regression analyses were performed to determine factors associated with uptake of IPTp-SP during pregnancy in Tanzania. Results: A total of 4764(68.6%) of pregnant women took at least one dose of IPTp-SP during Antenatal Care (ANC) visits. After adjusting for confounders, factors which were associated with uptake of IPTp-SP were; early antenatal booking, (AOR=1.495 p<.001); age group of pregnant woman [20 to 34 years (AOR=1.446, p=.001), more than 34 years (AOR=1.648, p<.001)]; wealth index [middle (AOR=1.418, p<.001), rich (AOR=1.589, p<.001)], education level [primary education (AOR=1.457, p<.001), secondary education AOR=1.653, p<.001]; parity [para 2 to 4 (AOR=1.213, p=.014), para 5 and above (AOR=1.226, p=.043)] and zone [Mainland rural (AOR=0.647, p=.019), Unguja (AOR=0.172, p<.001) and Pemba (AOR=0.310, p<0.001)]. Conclusion: Factors associated with uptake of IPTp-SP during pregnancy were; timing for ANC booking, age of pregnant woman, parity, level of education, and place of residence.
