BACKGROUND: The phenomenon of nutrition transition has been considered to greatly affect diet quality, especially of younger generations. OBJECTIVE: The aim of this study was to evaluate, through the use of the Diet Quality Index-International (DQI-I), several aspects of the diet quality in a sample of Mediterranean adolescents. METHODS: A cross-sectional investigation was conducted during two scholastic years (period October-May of 2012-13 and 2013-14) on 1643 adolescents attending 15 secondary schools of Sicily, southern Italy. Dietary information (through food frequency questionnaire), socio-demographic and lifestyle habits were collected. RESULTS: The mean age of adolescents was 12.4 years and the mean total modified DQI-I score was 52.3% of the total possible score. Adolescents reported an intake of fruit between 50 and 100% of the recommended intake, while for vegetable and fibers more than 40% did not achieve the 50% of the recommendation. BMI, physical activity, breakfast habit and KIDMED were positively associated with DQI-I. CONCLUSIONS: Diet quality of adolescent is low with a low adherence to traditional dietary patterns. Future intervention programs have to focus on increasing consumption of fresh fruits, vegetables and grains as well as in moderation of fat intake in order to achieve a better diet quality.

Abstract

BACKGROUND: The phenomenon of nutrition transition has been considered to greatly affect diet quality, especially of younger generations. OBJECTIVE: The aim of this study was to evaluate, through the use of the Diet Quality Index-International (DQI-I), several aspects of the diet quality in a sample of Mediterranean adolescents. METHODS: A cross-sectional investigation was conducted during two scholastic years (period October-May of 2012-13 and 2013-14) on 1643 adolescents attending 15 secondary schools of Sicily, southern Italy. Dietary information (through food frequency questionnaire), socio-demographic and lifestyle habits were collected. RESULTS: The mean age of adolescents was 12.4 years and the mean total modified DQI-I score was 52.3% of the total possible score. Adolescents reported an intake of fruit between 50 and 100% of the recommended intake, while for vegetable and fibers more than 40% did not achieve the 50% of the recommendation. BMI, physical activity, breakfast habit and KIDMED were positively associated with DQI-I. CONCLUSIONS: Diet quality of adolescent is low with a low adherence to traditional dietary patterns. Future intervention programs have to focus on increasing consumption of fresh fruits, vegetables and grains as well as in moderation of fat intake in order to achieve a better diet quality.
