Costs of recalled and recommended diets for pregnant women with type 1, type 2 and gestational diabetes.
OBJECTIVE
The costs associated with nutritious foods may be a barrier to healthy dietary choices and of particular concern to pregnancies complicated by diabetes. Therefore, a survey was conducted in a tertiary care diabetes and pregnancy clinic to compare the associated costs of actual food choices versus the cost of a constructed recommended diet.


METHODS
Women with types 1, 2 and gestational diabetes mellitus (GDM) completed 24-hour dietary recalls under the supervision of the research coordinator (Actual Diet). A Recommended Diet for this population was constructed independent of participant responses. Actual and Recommended Diets were standardized per 2000 kcal, priced and compared for content and cost.


RESULTS
Seventy-five women participated: 27 with GDM, 29 with type 1 diabetes and 19 with type 2 diabetes. There were no significant cost differences between Recommended and Actual Diets food choices expressed per 2000 kcal: Recommended Diet $10.14±3.72; Actual Diet GDM: $11.30±3.88; Actual Diet type 1 diabetes: $9.00±3.16; Actual Diet type 2 diabetes: $10.24±3.92. Percentage of fibre intake was lower for Actual Diets than Recommended Diet for all groups, while percentage of protein intake was lower in Actual than Recommended Diet for women with type 1 diabetes.


CONCLUSIONS
Clinical recommendations for healthy food choices may not be more expensive than actual choices made by pregnant women with diabetes.
