In The LILA project (​Leikki-Ikäisten LAsten ravinto) the diet quality of preschool-aged (2 to 6 years old) children was studied in a nationwide cohort. Utilisation of a previously developed short method for assessing diet quality (diet quality index) was evaluated in the public healthcare setting of well-baby clinics. The data were obtained in the spring and summer of 2016, and we are currently analysing and reporting the results.​
