Abstract
OBJECTIVE: Evaluate the effectiveness of nutrition education interventions for diabetes prevention. DESIGN: Retrospective cohort design. SETTING: Tertiary-care US Veterans' Hospital, July 2007 to July 2012, using pre-existing database. PARTICIPANTS: Prediabetic, adult veterans (n = 372), mostly men (94.4%, n = 351). INTERVENTIONS: Visits with existing nutrition education classes were collected. PRIMARY OUTCOME: diabetes status; predictors: visits/encounters, age, body mass index, weight change, and hemoglobin A1c. ANALYSIS: Cox proportional hazards method, χ(2) test, and logistic regression. RESULTS: In this sample, prediabetic veterans who received nutrition education were less likely to develop diabetes when compared with prediabetic veterans who did not receive nutrition education (hazard ratio, 0.71; 95% confidence interval, 0.55-0.92; P < .01). This difference remained significant after adjusting for body mass index and weight change. CONCLUSIONS AND IMPLICATIONS: Nutrition education was significantly associated with preventing the progression from prediabetes to diabetes in US Veterans participating in a nutrition education intervention at the Michael E. DeBakey Veterans Affairs Medical Center.
