Determinants for choice of home birth over health facility birth among women of reproductive age in Tanzania: an analysis of data from the 2015-16 Tanzania demographic and health survey and malaria indicator survey.

backgroundWhile evidence has shown an association between place of birth and birth outcomes, factors contributing to the choice of home birth have not been adequately investigated in Tanzania while more than 30% of deliveries occur outside of health care facilities, and more than 95% of those deliveries are assisted by non-medical providers who are often unskilled. The use of unskilled birth attendants has been cited as a factor contributing to the high maternal and neonatal mortalities in low-resources countries. This study aimed to identify determinants of choice for home birth over health care facility birth in Tanzania.

methodThis study used the 2015-16 Tanzania Demographic and Health Survey and Malaria Indicator Survey (2015-16 TDHS-MIS) dataset. A total of 2286 women of reproductive age (15-49 years) who gave birth within one year preceding the survey were included in the analysis. Both univariate and multivariable regression analyses were used to determine predictors for the choice of home-based childbirth over health care facility delivery.

resultsA total of 805 (35.2%) women had a home birth. After adjusting for confounders, the determinants for choice of home birth were: the level of education (primary education [AOR = 0.666; p = 0.001]; secondary and higher education [AOR = 0.417; p < 0.001]), in reference to no formal education; not owning a mobile phone (AOR = 1.312; p = 0.018); parity (parity 2-4 [AOR = 1.594; p = 0.004], parity 5 and above [AOR = 2.158; p < 0.001] in reference to parity 1); inadequate antenatal visits (AOR = 1.406; p = 0.001); wealth index (poorest (AOR = 9.395, p < 0.001); poorer (AOR = 7.701; p < 0.001); middle (AOR = 5.961; p < 0.001); richer (AOR = 2.557; p < 0.001)] in reference to richest women; and Zones (Southern Highlands, [AOR = 0.189; p < 0.001]; Southern, [AOR = 0.225; p < 0.001]; Zanzibar, [AOR = 2.55; p < 0.001]) in reference to Western zone.

conclusionsA large proportion of women birth at home. Unskilled providers such as traditional birth attendants (TBAs), relatives or friends attend most of them. Predictors for home-based childbirth included lack of formal education, poor access to telecommunication, poor uptake of antenatal visits, low socio-economic status, and geographical zone. Innovative strategies targeting these groups are needed to increase the use of health care facilities for childbirth, thereby reducing maternal and neonatal mortality in Tanzania.
