It both threatens the sustainability of nascent epidemiological transitions and raises prospects for counter transitions driven by indirect climate impacts on mortality, such as those from reemerging infectious diseases and by direct impacts of extreme climatic events. Objective: We investigate how the relationship between climate and mortality has changed as Antananarivo, Madagascar, progressed through the stages of the epidemiological transition, focusing on enteric infection mortality in children under 5. Methods: Using death registration, precipitation, and temperature time series data spanning over four decades, we model the climate–cause-specific mortality relationships during each stage of the epidemiological transition using generalized additive models. Results: While we find that enteric infection mortality has become less sensitive to low rainfall, higher temperatures, and climate extremes overall, it has become somewhat more sensitive to heavy rainfall. Mortality from remaining causes exhibits little climatic variation. Conclusions: While we find that childhood enteric infection mortality has become less sensitive to low rainfall and higher temperatures, it has become more sensitive to heavy rainfall. Mortality from other causes has also become less sensitive to high temperatures but has become slightly more sensitive to heavy rainfall while significantly more sensitive to low temperatures. Contribution: This is the first multidecade climate–mortality study of a city in sub-Saharan Africa out-side of South Africa. }, URL = {https://www.demographic-research.org/volumes/vol51/6/}, eprint = {https://www.demographic-research.org/volumes/vol51/6/51-6.pdf} }
