Background: Children and youth with diabetes have poor dietary behavior despite the higher likelihood of various cardiovascular disease risk factors. Hence, it is crucial to understand factors influencing children's consumption.

Objective: To evaluate the associations of supermarket and fast food outlet accessibility and availability with dietary intake among youth with diabetes.

Research Design and Methods: Information on residential location and dietary intake for 359 youth with diabetes aged 10 years and above was obtained from the Carolina site of the SEARCH for Diabetes in Youth study. Supermarket and fast food outlet data was obtained from the South Carolina Department of Health and Environmental Control and InfoUSA and was used to construct accessibility and availability measures.

Results: Increased availability and accessibility of supermarkets was significantly associated with higher Dietary Approaches to Stop Hypertension (DASH) adherence score, even after adjusting for individual-level correlates and urbanicity. For instance, each additional supermarket/square mile was significantly associated with a higher DASH score of 5.25 (p< 0.05). Associations of supermarket accessibility and availability with DASH score strengthened when controlled for fast food accessibility or availability. Fast food accessibility, however, was significantly associated with only specific food components (such as meat, sweets and low-fat dairy intake).

Conclusions: Accessibility and availability of supermarkets may be significantly associated with the overall dietary intake, and fast food outlet may be associated rather with specific food components. Efforts to promote environments conducive to healthy eating may significantly improve the overall dietary intake and reduce diet-related health complications among youth with diabetes.
