Diabetes Care May 30, 2013

OBJECTIVE There is debate regarding the clinical significance of well-established racial differences in HbA1c. We compared the associations of diabetes diagnostic categories for HbA1c and fasting glucose with clinical outcomes in black and white persons in the community.

We examined the associations of clinical categories of HbA1c (<5.7%, 5.7–6.4%, ≥6.5%) and fasting glucose (<100, 100–125, ≥126 mg/dL) with outcomes separately among 2,484 black and 8,593 white participants and tested for race interactions.  Read more
