A Conceptual Framework for Targeting Prediabetes with Lifestyle, Clinical, and Behavioral Management Interventions THOMAS J. BIUSO, M.D., M.B.A.,1 SUSAN BUTTERWORTH, Ph.D., M.S.,2 and ARIEL LINDEN, Dr.P.H., M.S.3,4 Prediabetes is a condition that does not fall squarely into the primary or secondary preven-
tion domain, and therefore tends to be inadequately addressed by interventions in either
health promotion or disease management. Prediabetes is defined as having an impaired fast-
ing glucose (fasting glucose of 100–125 mg/dL), impaired glucose tolerance (two-hour post-
prandial glucose of 140–199 mg/dL), or both. There is substantial evidence to suggest that even
at these blood glucose levels, significant risk exists for both micro- and macrovascular com-
plications. This paper introduces a conceptual framework of care for prediabetes that includes
both screening and the provision of up-to-date clinical therapies in conjunction with an evi-
dence-based health coaching intervention. In combination, these modalities represent the
most effective means for delaying or even preventing the onset of diabetes in a prediabetes
population. This paper concludes with a brief example in which these principles are applied
