Which fasting glucose threshold is used for the metabolic syndrome criterion?

Which fasting glucose threshold is used for the metabolic syndrome criterion?

• A. ≥5.0 mmol/L or diagnosed type 2 diabetes.
• B. ≥6.0 mmol/L or diagnosed type 2 diabetes.
• C. ≥6.5 mmol/L or diagnosed type 2 diabetes.
• D. ≥5.6 mmol/L or diagnosed type 2 diabetes.

Answer: (D)

The key idea is that metabolic syndrome uses a fasting glucose threshold to flag elevated blood sugar as part of the cluster of risk factors. The threshold is 5.6 mmol/L (100 mg/dL) or a known diagnosis of type 2 diabetes. This cut-off comes from clinical criteria (notably the IDF definition) designed to identify people at higher risk of diabetes and cardiovascular disease. If someone has already been diagnosed with type 2 diabetes, they meet this criterion regardless of their current fasting glucose. Values lower than 5.6 mmol/L don’t count unless diabetes is diagnosed.
