Impacts of climate change during pregnancy, perinatal period and infancy: a systematic review

Background Climate change is one of the most complex and important health threats of the 21st century. The knowledge of the impact of climate change on health is expanding rapidly. However, there has been no comprehensive assessment of the impact of climate change on the interlinked pregnancy, perinatal and infant periods. Hence, the objective of this study was to provide an overview of the effects of changing weather and climate hazards on maternal and infant health during pregnancy, the perinatal period and infancy. Methods We conducted a systematic review of peer-reviewed original articles and reviews found in PubMed, Web of Science, Embase, Cochrane, Global Health and WHO regional databases on the subject between January 2000 and May 2025. The included articles were in the English language, detailed exposure to climate change hazards during pregnancy, the perinatal period and up to 1 year of age in the child, with an outcome related to health. Results In total, 596 reviews and original articles were included in the analysis. Our findings demonstrate large differences in the number and types of studies for each climate-related hazard. Direct health effects from rising temperatures and extreme weather events, as well as indirect health effects such as infectious diseases, food insecurity, forced migration and socioeconomic changes due to climate change, have clear negative consequences for pregnant women and infants. Conclusions There is a large evidence base showcasing the harmful impact of climate change on pregnant women and infants through a variety of pathways. Action is urgently needed at all levels to address climate change and there is a need to implement large-scale mitigation and adaptation efforts that protect the health and well-being of pregnant women and infants everywhere.
