A Reliable, Valid, Sensitive and Simple Method to Quantify Carbohydrate Routine Consumption among Patients with Type 2 Diabetes

Daniel J. Cox

Objective: Growing evidence suggests postprandial hyperglycemia, driven largely by carbohydrate consumption, adversely affects A1c and cardiovascular health. The standard for quantifying carbohydrate intake is 24-hour dietary recall (ASA24), which is tedious, time consuming, under-samples due to a short measurement period, and is often impractical. An alternative is needed. Research Design and Methods: We developed the Carbohydrate Routine Consumption (CRC) scale, which quantifies weekly servings of 16 common high and low glycemic load foods and takes 5 minutes to complete and score. We administered the CRC and the ASA24 to 204 adults with type 2 diabetes. Results: The CRC was reliable, correlated with the ASA24 and had similar construct and discriminant validity. Conclusion: The CRC is psychometrically sound and easily employed by clinicians and researchers to document weekly servings of carbohydrate consumption.
