Post-natal care can be scarce within low-/middle-income countries (LMIC) and could be even more scarce following natural disasters. Using Marginal Structural Models (MSMs) and Demographic and Health Surveys (DHS) from 2003-2004 and 2008-2009 in Madagascar, we modeled the effect that tropical cyclones have on delivery places and personnel, polio 0 vaccines and vitamin A doses, health professional checking the health of the baby and mother after birth, and the size of the baby. We also tested the suitability of MSMs to control for selection processes. Based on logistic regressions and results from the 2008-2009 DHS, there is a need for more post-natal care after a disaster hits. Patients were less likely to see hospital/health center deliveries with a professional assisting the delivery, and receive Polio 0 vaccines and vitamin A doses in the post-disaster period.
