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.

The aim of the present study was to describe Mediterranean diet (MD) adherence within a population of adolescents and to analyse the association of multiple factors with adherence. This included a consideration of diverse physical and mental health indicators. The present study was conducted with a representative sample of 761 adolescents (14·51 (sd 1·63) years) from twenty-five educational centres in a northern region of Spain. MD adherence was evaluated, alongside their health-related quality of life, self-esteem, body image satisfaction, BMI, physical activity (PA) level, maximum oxygen consumption, hours of nightly sleep, socio-demographic factors and academic performance. Of the adolescent population, 49 % reported high MD adherence. Being female and having higher levels of PA were found to be predictive factors of adherence to the MD. In addition, maximum oxygen consumption, the presence of environments favourable towards PA engagement and higher self-esteem were also predictive in females, whilst better academic performance and more nightly sleep were additional predictors in males. The associations found between the MD and other health indicators and habits highlight the need to develop promotion strategies from an inter-disciplinary and transversal standpoint.

Aim Healthy habits are influenced by several factors such as geographical location. The aims of this study were to describe and compare healthy habits within two populations of sixth-grade primary school children (aged 11–12 years) from northern and southern Spain. Subjects and methods A cross-sectional study using two representative samples of school children was conducted. Participants came from Logroño (n = 329) in the north and Granada (n = 284) in the south of Spain. Socio-demographic and anthropometric variables, adherence to the Mediterranean diet, aerobic fitness, and healthy lifestyles were recorded. Results Boys reported a higher level of physical activity and aerobic fitness than girls (p = 0.000). Southern school children reported significantly higher adherence to the Mediterranean diet (♀: p = 0.041; ♂: p = 0.008), lower aerobic fitness (♀: p = 0.000; ♂: p = 0.042) and hours of nightly sleep (♀: p = 0.008, ♂: p = 0.007) than northern school children. Southern boys also reported lower levels of physical activity (p = 0.013). There were slight or moderate correlations among all habits measured (physical activity, diet, screen and sleep time). Additionally, the physical activity level was inversely related to weight status. Overweight and obese northern boys reported less physical activity than healthy-weight northern boys (p = 0.020) and overweight and obese southern girls reported less physical activity than healthy-weight southern girls (p = 0.024). Conclusions Results showed differences in physical activity, eating and sleep habits, and aerobic fitness according to geographical location. The relationships found among lifestyle habits indicate the need for health promotion interventions nationally and considering the differences discussed here.

Emotional health represents a significant burden on the mental health of university students. Adapting to a new learning environment and facing increased academic pressure make this period particularly vulnerable for their emotional health and well-being. The objective of the study was to analyse the prevalence of emotional and behavioural problems in university students and their association with lifestyle habits, and mental and physical health indicators. A cross-sectional study was conducted on a sample of 1268 students (23.65 ± 7.84 years) from a university in northern Spain during November 2020 and March 2021. An online questionnaire was administered, comprising the self-report Strengths and Difficulties questionnaire, the Trait Meta-Mood Scale, the Rosenberg Self-Esteem Scale, the Satisfaction with Life Scale, the Perceived Stress Scale, the SENTIA-Brief Scale, the KIDMED questionnaire, the International Physical Activity Questionnaire-Short Form, the Alcohol Use Disorders Identification Test, and the Compulsive Internet Use Scale. 27.60% of students exhibited some form of emotional and behavioural problem. Students who did not present emotional and behavioural problems showed lower perceived stress, reduced suicidal behaviour and emotional intelligence deficits, as well as lower alcohol consumption and compulsive internet use (p < 0.001). Additionally, they reported higher engagement in physical activity and greater adherence to the Mediterranean diet (p < 0.001). The study shows that emotional and behavioural problems are recurring among university students, and given that modifiable psychosocial and lifestyle factors are associated with these issues, it underscores the need to develop multidisciplinary intervention strategies.
