Abstract
We examined the association of diet quality with diet cost in a sample of youth with
type 1 diabetes, for whom diet is an important component of medical management. Differences
in food group spending by diet quality were also examined to identify potential budgetary
reallocation to improve overall diet quality. Families of 252 youth with type 1 diabetes
aged 8 to 18 years completed 3-day youth diet records. Cost of each food reported
was calculated based on the average price obtained from two online grocery stores.
Diet cost was estimated as average daily cost of foods consumed. The Healthy Eating
Index 2005 (HEI2005), Nutrient Rich Foods Index version 9.3, and Whole Plant Food
Density scores were evaluated. Differences in mean daily diet cost across tertiles
of HEI2005, Nutrient Rich Foods Index version 9.3, and Whole Plant Food Density were
modest, with none reaching statistical significance. Those in the upper tertile of
HEI2005 spent more on whole fruit, whole grains, lean meat, and low-fat dairy, and
less on high-fat meat and high-fat dairy compared with those in the lower tertiles.
Higher-quality diets can be obtained at comparable costs to lesser-quality diets,
suggesting that cost need not be an insurmountable barrier to more healthful eating.
Reallocation of spending may increase overall quality without substantially increasing
overall spending. Findings suggest potential strategies for assisting families of
youth with type 1 diabetes in identifying cost-effective ways to achieve a more healthful
diet.
