Abstract
Purpose
This study aimed to assess the dietary patterns of adolescents using a food-based diet quality index and their compliance with a healthy dietary guideline
Methods
Participants included 71,553 Brazilian adolescents (12–17 years old) from the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional school-based multicenter study.. Dietary intake was measured by one 24-h recall. A second recall was collected in a random subsample (~ 10%) to correct within-person variability. The Diet Quality Index for Adolescents adapted for Brazilians (DQIA-BR) was used to measure the overall quality of the dietary intake. The National Cancer Institute method was applied to estimate usual dietary intake. The DQIA-BR and the distribution of its components (quality, diversity, and equilibrium) were analyzed according to sex, geographical area, and type of school
Results
The mean (SD) DQIA-BR scores were 14.8% (6.1%) for females and 19.0% (6.3%) for males. All analyzed strata revealed low scores of DQIA-BR and its components. The median usual intake was five to sevenfold below the recommendations for vegetables and fruits and approximately twofold below the recommendations for dairy. The highest DQIA-BR mean scores were found in the northern region [17.0% (6.4%), females; 20.7% (6.3%), males]. Adolescents in both types of schools had relatively similar median intakes of snacks (~ 85 g) and sugared drinks (~ 600 ml)
Conclusions
The overall diet quality of Brazilian adolescents is inadequate based on evaluated parameters in all regions and socioeconomic backgrounds.
