Highlights

•	This review analyzed human studies examining climate change impacts on diabetes.
•	Extreme temperatures and natural disasters worsen diabetes outcomes.
•	Climate impacts on pediatric, gestational, and type 1 diabetes are understudied.
•	Studies from low and middle-income countries are grossly underrepresented.
•	Protecting those with diabetes requires addressing climate threats.

ABSTRACT

Introduction

Climate change poses myriad threats to human health, including deleterious impacts on chronic diseases such as diabetes mellitus. A scoping review was conducted to clarify the current state of knowledge regarding climate change impacts on the incidence, progression, complications, and management of diabetes.

Methods

Literature was searched across PubMed, EMBASE, and Web of Science combining terms related to "climate change" and "diabetes". In addition, the Journal of Climate Change and Health was hand searched. Primary-source, peer-reviewed human studies were included in the analysis. Animal studies, plant-based research, studies focused upon pollution, and review articles were excluded.

Results

Seventy-three articles met the inclusion criteria. Articles predominantly focused upon heat-related health effects, noting linkage to deteriorating glycemic control, increased mortality, and more frequent emergency room visitations. While studies examined mortality linked to heat, cold, and natural disasters, a notable proportion failed to specify precise causes of death. Significant data gaps were identified regarding climate impacts on diabetes-related complications and non-glycemic metabolic outcomes as well as impacts on pediatric, gestational, and type 1 diabetes. Few studies focused upon low and middle-income countries where climate impacts are predicted to be greatest.

Conclusion

Various manifestations of climate change are linked to multiple adverse outcomes among those with diabetes. However, current data is sparse regarding climate impacts on vulnerable populations, diabetes-related complications, and geographic regions most vulnerable to climate change that are also experiencing the greatest rise in diabetes rates. Mitigating the impact of climate change on those with diabetes requires closing these data gaps.
