HbA1C not enough to monitor diabetes in patients of African descent: Study
African descent populations in the United States have high rates of type 2 diabetes and are incorrectly represented as a single group, despite being comprised of African American (91%), Afro-Caribbean (4.7%), and African (3.7%) people. In a recent study, researchers have addressed the inadequately characterized glycemic status among heterogeneous African descent populations. They found that the HbA1c level performs differently among persons of African descent, depending upon their specific ethnicity. The research has been published in the journal Preventing Chronic Disease on March 11, 2021.
Current glycated haemoglobin A1c (HbA1c) cutoffs (HbA1c 5.7% to less than 6.5% for prediabetes; HbA1c of 6.5% or higher for type 2 diabetes), determined from predominantly White population cohorts, may perform suboptimally in evaluating glycemic status in this diverse population of African American, Afro-Caribbean, and African populations. To ensure accurate detection of type 2 diabetes, there is a need to understand the ability of HbA1c to correctly classify type 2 diabetes status and to evaluate interethnic variation among African American, Afro-Caribbean, and African people. Therefore, Dr Margrethe F. Horlyck-Romanovsky, PhD and her team conducted a study to assess glycemic status among African American, Afro-Caribbean, and African people.
