Climate-induced Neonatal Deaths
Context: Recent research suggests that climate change caused 32% of heat-related neonatal deaths in poor countries between 2001 and 2019.
Study Overview: Recent research published in Nature Communications (June 29, 2024) highlights climate change’s direct impact on newborn survival in low- and middle-income countries (LMICs).
Temperature-Related Effects:
- Increased Neonatal Deaths: Climate change has led to a 32% increase in heat-related neonatal deaths from 2001 to 2019.
- Decrease in Cold-Related Deaths: Conversely, cold-related neonatal deaths decreased by 30% during the same period due to climate change.
Vulnerability to Temperatures:
- Risk Across Temperatures: Both high and low ambient temperatures pose risks to neonatal health in LMICs.
- Higher Vulnerability to Heat: Very young neonates (0-1 days old) are particularly vulnerable to heat-related mortality.
Regional Impact:
- Sub-Saharan Africa: Countries in this region, such as Sierra Leone, Ethiopia, Liberia, and Nigeria, have experienced significant impacts, with increased heat-related mortality rates.
- Country-Specific Impacts: Philippines, Haiti, and Rwanda saw substantial increases in heat-related neonatal deaths attributed to climate change.
Public Health Implications:
- Need for Interventions: Urgent public health interventions are required to protect newborns from the adverse effects of temperature extremes.
- Global Disparities: Sub-Saharan Africa and southern/central Asia continue to bear the highest burden of neonatal deaths, highlighting disparities in global healthcare.
Conclusion: The findings underscore the critical importance of climate adaptation strategies and targeted healthcare interventions to mitigate the impact of climate change on neonatal mortality rates in vulnerable regions.
