Rationale: Diet Quality Index-International (DQI-I) which consists of diversity, adequacy, moderation, and general balance categories is a tool created to examine the diet quality of populations. Mediterranean diet (MD) is a nutritional model that reduces the risk of many chronic diseases (1). This study was carried out to evaluate the association between body mass index (BMI) and compliance with DQI-I and MD in healthy adults.

Methods: This cross-sectional descriptive study included 926 healthy individuals aged 19 to 64, between February and June 2020. The questionnaire, consisting of general demographic information, Mediterranean Diet Assessment Tool (PREDIMED), and a 24-hour dietary recall, was applied by phone due to COVID-19 pandemic restrictions. Body weight and height was self-claimed by participants. DQI-I was calculated according to 24-hour dietary recall by a trained dietitian.

Results: The average age of the participants was 35.1±13.40 years and 50.4% of the participants were female. The average BMI was 25.1±4.50, the average DQI-I score was 53.4±9.82 (out of 100 points), and the PREDIMED score was 5.9±2.21 (out of 12 points). There was a significant positive correlation between DQI-I scores and BMI (r=0.094, p=0.004) however there was no correlation between PREDIMED scores and BMI (r=0.022, p>0.05) (Table 1). Average scores for DQI-I subsections were 15±3.59 (78.5%) for diversity (out of 20 points); 26.2±6.11 (65.5%) for adequacy (out of 40 points); 9.9±5.61 (33%) for moderation (out of 30); and 1.7±2.18 (17%) for moderation (out of 10 points).
