RESUMO
INTRODUCTION: Childhood and adolescence are key stages to promote a healthy lifestyle. OBJECTIVE: To analyze the relationship between weight status, physical activity and the Mediterranean diet in schoolchildren in the Region of Murcia. METHODS: Cross-sectional descriptive study with 520 schoolchildren aged 8-17 years. The weight status was calculated through the body mass index. The Mediterranean diet was found through the KIDMED questionnaire and physical activity was estimated using the IPAQ-C and IPAQ-A questionnaires. RESULTS: The Mediterranean diet is not significantly associated with sex (P<.537) or weight status (P<.417) but it maintains a relationship of dependence with age (P<.010) and the level of physical activity (P<.000). Schoolchildren in normal weight and assets have a greater follow-up to the Mediterranean diet than their overweight and sedentary peers (P<.000). CONCLUSION: The Fat but fit phenomenon applied to the Mediterranean diet is confirmed.
