OBJECTIVE - Food insecurity is hypothesized to make diabetes self-management more difficult. We conducted a longitudinal assessment of food insecurity with several diabetes self-care measures. RESEARCH DESIGN AND METHODS - We conducted a secondary, observational analysis of 665 low-income patients with diabetes, all of whom received self-management support as part of a larger diabetes educational intervention. We analyzed baseline food insecurity (measured by the U.S. Department of Agriculture Food Security module) in relation to changes in hemoglobin A1c(HbA1c) as well as self-reported diabetes self-efficacy and daily fruit and vegetable intake.

RESULTS - Overall, 57% of the sample had an income
