Background: The aim is to investigate the association between diet quality and daily price of foods consumed among Iranian diabetic patients.

Methods: This cross‑sectional study was conducted among 200 patients with type 2 diabetes mellitus (T2DM) aged 30–70 years. General information, socioeconomic status, anthropometric and biochemical characteristics, and food prices were collected by pretested questionnaires. Dietary intakes were assessed using a semi‑quantitative reliable and valid food frequency questionnaire. Modifed nutritionist IV and SPSS software were used for analyses.

Results: The results of the present study indicated a direct relationship between total daily price of diet and nutrient adequacy ratio of Vitamin D, Vitamin B1, selenium, zinc, magnesium, potassium, and mean adequacy ratio of 11 micronutrients (Vitamin C, Vitamin E, Vitamin D, Vitamin B1, Vitamin B6, Vitamin B12, selenium, zinc, calcium, magnesium, and potassium) (P < 0.05). Furthermore, the total daily price of diet had a positive association with dietary intakes of protein, Vitamin D, Vitamin B1, selenium, zinc, magnesium and potassium among type 2 diabetic patients (P < 0.05). However, no signifcant relationship was observed between the total daily price of diet and anthropometric indices, biochemical characteristics, and socioeconomic status of participants in the present study (P > 0.05).

Conclusions: This study showed that dietary quality and dietary intakes of energy, protein, and micronutrients were directly associated with the total daily price of foods among Iranian patients with type 2 diabetes.
