ObjectivesThe aim of this study was to assess the impact of Mediterranean diet (MD) and physical activity on metabolic syndrome (MS) prevalence in children and adolescents. Material and methodsThis cross-sectional study was carried out in 863 boys and 780 girls, 6–14years old, from primary and secondary schools in a 14-town Southern Italian community. We modified the KIDMED questionnaire to adapt it to the local reality. ResultsPoor adherence to MD was seen in 18.4% of children and adolescents, while 81.6% had a medium-high compliance and the prevalence of MS was 6.6% and 3.7% respectively (OR: 1.8; 95% C.I.: 1.06–3.11; p=0.013). When participants had less physical activity, MS was more frequent as compared to those more active (5.3% versus 2.3%; OR: 2.3; 95% C.I.: 1.3–4.3; p=0.0068) which had a parallel counterpart when comparing those accustomed to seeing television for less or more than 5h per day and MS prevalence was 12.3% versus 3.8% (OR: 3.38; 95% C.I.: 1.66–6.86, p=0.0008), respectively. Finally, there was a specific abnormality in triglyceride levels, both in girls and boys, when participants were classified according to bad lifestyles, based on the combined evaluation of scarce adherence to MD and less extracurricular physical activity, accompanied by a 7-fold increased prevalence of MS as compared to those with the best lifestyle (11.0% versus 1.6%; p=0.025). ConclusionsThere is an apparent importance of healthier lifestyle habits including physical activity and adherence to the MD also among children and adolescents.
