Mediterranean Journal of Nutrition and Metabolism publishes original scientific papers on metabolism, including diabesity and eating disorders; nutrition (epidemiological, basic, clinical and artificial); dietary and nutritional practices and management and their impact on health from prevention to treatment.
The journal hosts the proceedings of relevant congresses and presents shorter notices focused on the original character of the Mediterranean nutritional civilisation.

Abstract: PURPOSE: The purpose of the study was to explore possible links between adherence to the Mediterranean diet (MeD), general dietary behaviors, energy balance behaviors, excess body weight other lifestyle habits and academic performance in Greek adolescents. METHODS: A total of 520 students (256 boys; 264 girls), 15–18 years old, were recruited from the four Departments of Secondary Education in the area of Athens, Greece. Students completed a specifically designed energy balance behaviors questionnaire together with the KIDMED index, which evaluates the degree of adherence to the MeD. In addition, various other questionnaires were used such as the…Physical Activity and Lifestyle Questionnaire (PALQ), the STAI questionnaire to measure anxiety levels, the Self-Perception Profile for Adolescents (SPPA) and selected subscales of the Multidimensional Body-Self Relations Questionnaire (MBSRQ) to assess the adolescents’ attitudes towards health. Academic performance was assessed using the students’ average score for all school subjects. Standard anthropometric measurements were also taken. RESULTS: Block stepwise regression analysis was conducted. Results indicate that family meals (β= 0.087, P = 0.017), adherence to the MeD (0.176, P = 0.001), soft drinks consumption (β= –0.104, P = 0.004), TV viewing (β= –0.068, P = 0.047) and smoking (β= –0.159, P = 0.001) are significant factors in predicting academic performance in adolescents. CONCLUSION: Poor adherence to the MeD, small number of family meals, high soft drinks consumption and smoking, may have a negative influence on academic performance in adolescents.
Abstract: BACKGROUND: Adolescence is a period characterized by important psychological and physical appearance changes. OBJECTIVE: The aim of our study is the assessment of the frequency of different nutritional status grades of Algerian schoolchildren and adolescents. METHODS : We conducted a survey among 2 278 schoolchildren and adolescents of 8–18 years-old in the period 2013-2014. For each child the height and weight were measured and body mass index (BMI) was calculated. The prevalence of, overweight and obesity was assessed using the World Health Organization (WHO-2007) and the International Obesity Task Force (IOTF) criteria. Pearson’s chi-square test was…used to assess significant differences in prevalence. All analyses were completed using the SPSS statistical package, version 20. RESULTS: The prevalence of overweight and obesity were respectively 28.8% (95% CI, 26–31.6); 10.5% (95% CI, 8.6–12.4) for the boys and 25.5% (95% CI, 23–28); 5.8% (95% CI, 4.4–7.1) for the girls. Sex as a risk factor for obesity in Algerian schoolchildren and adolescents; the odds ratio of obesity was 2.50 times (95% CI, 1.40–3.20; P < 0.017) higher in boys compared to girls. CONCLUSION: The results revealed the high prevalence of obesity and overweight. The absence of a national database on the nutritional status of children and adolescent needs the establishment of a monitoring program of their nutritional status to avoid any complications in the adult age.
