Objectives: This study aims to describe the dietary status of Turkish adults using two different versions of the Healthy Eating Index (HEI). Methods: In this cross sectional study, 494 healthy participants (311 females) with randomly selected and living in Ankara were included between September 2013 and March 2014. A questionnaire was completed and anthropometric measurements (weight and height) were performed. The 24-h dietary recall of individuals was collected. Diet quality was measured through HEI-2005 and HEI-2010 scores. Results: The mean age, body mass index (BMI), HEI-2005 and HEI-2010 scores of individuals were 32.9 +/- 10.8 years; 25.0 +/- 4.8 kg/m(2); 56.1 +/- 13.9 and 41.5 +/- 13.7 points, respectively. Significant differences were found between mean HEI-2005 and HEI-2010 scores (p < 0.05). The individual's whose diet quality needs to be improved according to mean HEI-2005 score, had poorer diet based on mean HEI-2010 scores. The highest mean HEI-2005 and HEI-2010 scores were stated in female, in subjects had low education levels, aged 51 years or older and in overweight groups (p < 0.05). Both versions of healthy eating indices were correlated positively with BMI and age Conclusion: Diet qualities of the individuals are associated with age, gender, education and BMI. Although the components and scores in HEI-2010 version were changed from the version of HEI-2005, the changes may encourage healthy choices of some food group. HEI-2010 gives more attention to food quality than HEI-2005. Thus, in the present study it was concluded that HEI-2010 provided more precise results about diet quality.
