Background: The Mediterranean Diet is recognized as one of the healthiest dietary patterns; however, in recent years, a decline in adherence has been observed in Mediterranean countries. University students represent a particularly vulnerable population, as starting university introduces new influences and responsibilities that directly impact their lifestyle and health. Objective: Analyze adherence to the Mediterranean Diet among university students and its association with other lifestyle habits and mental and physical health indicators. Methods: A cross-sectional study was conducted with a sample of 1268 students (23.65 ± 7.84 years) from a university in northern Spain between November 2020 and March 2021. An online questionnaire was administered to assess Mediterranean Diet adherence along with variables such as perceived stress, self-esteem, life satisfaction, suicidal behavior, emotional and behavioral problems, emotional intelligence, physical activity, sedentary behavior, alcohol consumption, and compulsive internet use. Results: 29.26% of students had high adherence to the Mediterranean Diet. Regression analysis indicated that high adherence was associated with higher levels of emotional intelligence, as well as lower levels of suicidal ideation, emotional problems, and compulsive internet use. Conclusions: The associations found between Mediterranean Diet and other indicators and lifestyle habits highlight the need for interdisciplinary promotion strategies within the university ecosystem.

Adolescence is a decisive stage in human development in which intense physical, psychological, emotional and social changes are experienced. There are many influential factors in health, highlighting among them the environment. The objective of the study was to analyse the lifestyle differences associated with the health of adolescents as a function of rural and urban environment. A cross-sectional study was conducted with a sample of 761 students (14.51±1.63 years) from 25 educational centers in a region of northern Spain, distributed between 650 urban and 111 rural students. Life habits and different indicators of physical, psychological and social health were evaluated, assessing the level of physical activity, maximum oxygen consumption, hours of night sleep, quality of life related to health, self-esteem, adherence to the Mediterranean diet, the environment and the socioeconomic level. Adolescents in rural areas reported a greater number of hours of night sleep and higher levels of HRQL, both as a whole, and specifically in psychological well-being, school environment and autonomy and parents. Adolescents in urban areas reported higher levels of physical activity between 6:00 p.m. and 10:00 p.m., and a higher consumption of fast food. The results show the need for strategies aimed at counteracting the negative influence that physical and sociodemographic factors typical of urbanized areas exert on HRQL. On the other hand, in relation to lifestyle habits, a wider range of extracurricular physical activities in rural areas would be recommended.

Compliance with the recommendations regarding physical activity by adolescents is poor despite its proven benefits on their health. The objective of this study was to analyse the physical activity engagement in an adolescent population, evaluating its relationship with various indicators of physical and psychological health, as well as the influence of different sociodemographic variables as potential predictors. A cross-sectional study was applied to a sample of 761 students (14.51 ± 1.63 years) from 25 schools in La Rioja (Spain). Physical activity engagement, hours of nightly sleep, maximum oxygen uptake, health-related quality of life, self-esteem, body image satisfaction, adherence to the Mediterranean diet, body mass index, academic performance and various sociodemographic factors were analysed for all participants. Being older, being a girl, having a low/medium socioeconomic level, living in unfavourable environments for practicing physical activity, not doing extracurricular sports activities, and being dissatisfied with body image were all predictors of a low physical activity engagement. Likewise, physical activity engagement reported positive associations with health-related quality of life, self-esteem, hours of nightly sleep, adherence to the Mediterranean diet and maximum oxygen uptake. Interventions aimed at promoting physical activity must take into account these predictive factors, trying to favor their performance, especially in the most vulnerable groups.

Background: Mental health is defined as a state of emotional, psychological, and social well-being, and has been shown to be positively associated with self-esteem and quality of life. It is important to note that mental health is dynamic and influenced by a wide range of social, biological, and behavioral factors. Therefore, the aim this study was to describe the health-related quality of life and self-esteem in adolescents, examining their relationship with various health indicators, lifestyle habits, and sociodemographic variables. Method: A cross-sectional study was conducted with a representative sample of 761 students (14.51 ± 1.63 years). Health-related quality of life, self-esteem, satisfaction with body image, adherence to the Mediterranean diet, physical activity practice, hours of nightly sleep, maximum oxygen consumption, body mass index, academic performance, and various sociodemographic factors of all participants were analyzed. Results: Regression analysis showed that body satisfaction and academic performance were associated of both health-related quality of life and self-esteem. Additionally, physical activity, age, and favourable settings for physical activity engagement were also found to be related to health-related quality of life, whilst adherence to the Mediterranean diet, hours of nightly sleep, maximum oxygen consumption and socioeconomic status were associated with self-esteem. Conclusions: Given the associations found between health-related quality of life and self-esteem with lifestyle habits and sociodemographic indicators, there is an urgent need to develop interdisciplinary and cross-cutting promotion strategies to improve the mental health of adolescents.
