Orr CJ, et al. - Using repeated cross-sectional analysis of nationally-representative data, researchers determined if adults with diabetes mellitus have changed their diet quality over time and analyzed trends in socioeconomic disparities in diet quality. The study sample consisted of 5,882 adult candidates, aged 20 or older, with diabetes mellitus type 1 or 2 who finished 24-hour dietary recalls. Findings revealed that 29% of US adults with diabetes had less than a high school diploma, 17% had income < 100% of federal poverty level, and 15% were food insecure. Significant diet quality disparities are seen in adults with both diabetes and lower socioeconomic status (SES) and/or food insecurity, and these disparities have not gotten better over time. In realizing dietary improvements, lower SES individuals are over a decade behind their peers. This constitutes an important obstacle to the ideal management of diabetes and an important public health concern.
