HealthDay News — For individuals with normal fasting glucose but not those with impaired fasting glucose (IFG), a higher number of ideal cardiovascular health (CVH) components correlates with a lower risk for diabetes, according to a study published online Jan 15 in Diabetologia.

Joshua J. Joseph, MD, from The Ohio State University Wexner Medical Center in Columbus, and colleagues conducted a secondary data analysis in the Reasons for Geographic and Racial Differences in Stroke study. Incident diabetes was assessed among 7758 participants without diabetes in 2003 to 2007; participants were followed for 9.5 years. Participants were characterized based on the number of ideal CVH components 0 to 1, 2 to 3, and 4 or more).

The researchers identified 891 incident diabetes cases. For participants with 4 or more vs 0 to 1 ideal CVH components, the risk was reduced significantly among those with normal fasting glucose (risk ratio, 0.20; 9% confidence interval, 0.10 to 0.37) and reduced nonsignificantly with baseline IFG (risk ratio, 0.87; 95% confidence interval, 0.58 to 1.30). Compared with African-Americans, white participants had a stronger magnitude for the association between ideal CVH components and lower diabetes risk (P=.0338).

“The lower magnitude of risk reduction with ideal CVH among those with IFG warrants further investigation and suggests this group requires higher intensity interventions to lower long-term diabetes risk,” the authors write.
