Anthropometric, Lifestyle Characteristics, Adherence to the Mediterranean Diet, and COVID-19 Have a High Impact on the Greek Adolescents' Health-Related Quality of Life.

OBJECTIVE: The study aimed at analyzing the relationship between anthropometric characteristics, lifestyle, and dietary habits, as well as the burden of the pandemic on the health-related quality of life among Greek pupils. RESEARCH METHODS AND PROCEDURES: On the whole, 2088 adolescents aged 12-18 years from Attica, Greece, were enlisted in this school-based cross-sectional study that took place in May-December 2021. Health-related quality of life was estimated through the KIDSCREEN-27 questionnaire, adherence to the Mediterranean diet-through the KIDMED test. For the empirical and econometric analyses, the Mann-Whitney U and Kruskal-Wallis means comparison tests were utilized; multiple linear regression was used accordingly. RESULTS: The present study provides evidence to the fact that boys, younger adolescents, adolescents living with both parents and with highly educated mothers had a better health-related quality of life. Concerning their eating practices, positive predictors were consuming a better-quality breakfast, having all five meals daily, consuming lunch and dinner with parents, and higher adherence to the Mediterranean diet. Moreover, sufficient night sleep time, fewer hours spent on screen viewing, more frequent walks, and having hobbies were linked to the health-related quality of life with a positive sign. In contrast, negative predictors were higher body mass index and everyday life difficulties due to the COVID-19 pandemic crisis. CONCLUSIONS: Greek adolescents' anthropometric characteristics, BMI, lifestyle and sedentary habits, eating habits, and adherence to the Mediterranean diet were significantly related to their perceived health-related quality of life during the pandemic.

Greek adolescents and the Mediterranean diet: factors affecting quality and adherence.

OBJECTIVE: Evaluation of adolescents' adherence to the Mediterranean diet (AMD) and the connection to anthropometric, demographic, socioeconomic, and lifestyle characteristics. METHODS: In all, 525 adolescents aged 12 to 18 y from Athens and Heraklion, Greece, participated in this cross-sectional, school-based study, which took place during March and April 2012. The dependent variable was scored on the KIDMED test, with score >8 indicating an optimal Mediterranean diet (MD). Analysis included χ(2) test and Student's t test for the association between variables. Linear regression analysis was used to identify the determinants of AMD. A two-sided P-value < 0.05 was considered statistically significant. RESULTS: Of the participants, 21% had very good AMD. Positive predictors were mother's educational level (P < 0.01), living with both parents (P < 0.05), and residing in a smaller city (P < 0.01). Negative predictors were age (P < 0.05), >4-h computer use per day (P < 0.01), and lack of physical activity (P < 0.01). No correlation was found between AMD and body mass index (P > 0.05). CONCLUSIONS: Several anthropometric, demographic, socioeconomic, and lifestyle characteristics were significantly associated with AMD. It is highly important that children and adolescents adhere at a very young age to the MD as the healthier dietary choice. Further researchers might explore whether the economic recession in Greece has any effects on adolescents' dietary habits.
