In the United States, diabetes affects more than 30 million people, with Type 2 diabetes accounting for 90-95% of cases. Additionally, more than a third of US adults (84 million) have prediabetes. Many people with diabetes don’t even know they have it (25% of those with diabetes and 90% of those with prediabetes)! Since Type 2 diabetes is a known modifiable risk factor for COVID-19 severity and mortality, knowing your status can help your focus your health efforts on reducing your risk.

Type 2 diabetes and Hemoglobin A1c

Type 2 diabetes is caused by too much glucose in the blood primarily due to insulin resistance, which is when the body doesn’t use insulin as well as it should. Hemoglobin A1c, or HbA1c, is the compound formed in the blood when a hemoglobin molecule in a red blood cell binds with a glucose molecule. The more glucose that enters the bloodstream, the higher the amount of hemoglobin A1c.

Measuring the percentage of hemoglobin A1c in the blood provides information about the average blood glucose levels over the prior few months. Generally levels below 5.7% are considered normal, 5.7% to 6.4% are considered prediabetic, and levels of 6.5% or higher are considered diabetic. This test can be used by a health care professional, along with other tests and a physical exam, to help diagnose type 2 diabetes and prediabetes and for diabetes management.

How can I find out my Hemoglobin A1c levels?

GrassrootsHealth offers a Hemoglobin A1c dried blood spot test. Knowing your Hemoglobin A1c levels can enable you to focus your health efforts on lifestyle changes, such as diet and exercise, which can help prevent of even reverse prediabetes. Additionally, studies have shown that increasing vitamin D and omega-3 levels can lower Hemoglobin A1c levels. Be sure to consult your practitioner if you think you are at risk for diabetes and for specific recommendations for your health.

What are the Hemoglobin A1c levels among GrassrootsHealth Participants?

Among the 233 participants who tested their Hemoglobin A1c levels, the average level was 5.2%. As you can see from the chart below, 75% of these participants have levels in the normal range, 19% have levels in the range indicating prediabetes, and 6% have levels in the range indicating diabetes. With diabetes being a top risk factor for COVID-19, this data suggests that one-quarter (25%) of participants may be at a higher risk for COVID-19 severity and mortality.

Additionally, among those who completed two or more tests, 73% of those with levels 5.7% or higher (prediabetes or diabetes) lowered their hemoglobin A1c levels after their first test.
