HbA1c should be assessed how often for athletes with type 1 diabetes?

• A. Every 3 to 4 months
• B. Every 6 months
• C. Every year
• D. Only when fasting glucose is abnormal

Answer: (A)

HbA1c shows how well blood glucose has been controlled on average over the past 2 to 3 months, so monitoring it at a roughly quarterly cadence lines up with what this test reflects and allows timely adjustments to insulin, meals, and exercise plans for athletes. Checking every 3 to 4 months gives you a meaningful view of trends as training cycles, competition schedules, and travel can shift glycemic control, helping you stay on target without waiting too long for changes to show up. If you wait until fasting glucose is abnormal, or check only yearly or every six months, you miss the broader picture of glucose exposure that HbA1c provides and risk delayed responses to changes in activity or routine. Therefore, assessing HbA1c every 3 to 4 months is the most appropriate approach.
