Approximately 30 million U.S. adults currently have diabetes, and an additional 86 million have pre-diabetes. The incidence of diabetes has increased substantially over the past 30 years, including among children. Estimates place the direct and indirect costs of diabetes at a staggering $218 billion annually.1 Like many other diseases, disparities on the basis of race and income are apparent with diabetes. Non-Hispanic blacks, Hispanics, Native Americans, and socioeconomically disadvantaged groups are more likely to develop diabetes than non-Hispanic whites and socioeconomically advantaged groups.
Despite the enormous economic and social costs associated with diabetes, it remains a struggle to apply what we know about diabetes prevention to communities at the highest risk. We have robust evidence from randomized controlled trials that changing health behaviors, including adopting a healthy diet and regular exercise routine and subsequent weight loss, will significantly lower the risk of diabetes. Unfortunately, these promising findings only appear to apply to the short-term. Even worse, results from community-based translation efforts have been much more modest than expected, and show only limited promise of reducing long-term diabetes risk. In response, leaders at the National Institutes of Health have noted that many efforts at translating clinical findings into community settings are “limited in scope and applicability, underemphasizing the value of context.”2
