Real-World Insights Into Hypoglycemia Risk While Driving in Teens and Young Adults With Type 1 Diabetes

Area of Science:

• Endocrinology
• Neuroscience
• Public Health

Background:

• Limited research exists on glucose levels and hypoglycemia risk in drivers with diabetes.
• No prior studies have specifically analyzed glucose patterns in teenage or emerging adult drivers with type 1 diabetes (T1D).

Purpose of the Study:

• To explore glycemic patterns in young drivers with T1D.
• To assess adherence to clinical guidelines for driving.
• To identify trends for improving road safety in this demographic.

Main Methods:

• Collected continuous glucose monitoring (CGM) data from five T1D drivers (age 17-21) over one month.
• Categorized driving trips into short (<60 min) and long (≥60 min).
• Defined hypoglycemia as CGM readings <70 mg/dL for four consecutive readings; excluded trips <10 min.

Main Results:

• 284 trips analyzed; average 56.8 trips per driver.
• No hypoglycemia occurred in short trips (n=227) when starting glucose was >90 mg/dL.
• Five hypoglycemia events occurred in short trips (n=32) starting with glucose 70-90 mg/dL.
• 17.5% of short trips began with glucose <70 mg/dL.
• No hypoglycemia events were observed in eight long trips, all starting with glucose >90 mg/dL.

Conclusions:

• Real-world data from young T1D drivers support the American Diabetes Association recommendation of starting glucose >90 mg/dL for driving.
• Further research with larger sample sizes is needed to enhance road safety for young drivers with T1D.
