Trent Honda, dean of the School of Health Sciences, is the lead author of a new study published in Diabetes Research and Clinical Practice that links air pollution to an increased risk of serious health complications among people with Type 1 diabetes.

The study, titled “Ambient particulate air pollution is associated with higher risk of microvascular complications and diabetic ketoacidosis among persons with type 1 diabetes mellitus in an observational survival study,” found that higher exposure to fine particulate air pollution (PM2.5) is associated with greater risks of diabetic ketoacidosis and microvascular complications, including eye and nerve damage.

Drawing on data from nearly 13,000 people with Type 1 diabetes, the researchers discovered that even modest increases in air pollution exposure were associated with significantly higher risks for these complications. The study highlights how environmental factors can influence chronic disease outcomes and points to the importance of air quality as a potential target for public health interventions.

Honda’s role as lead author underscores his expertise in advancing research that bridges environmental health and chronic disease management. His work reflects Quinnipiac’s commitment to addressing pressing public health challenges through interdisciplinary research and leadership in health sciences.
