Um resumo do estado da arte acerca da Síndrome Metabólica. Conceito, operacionaliza？？o, estratégias de análise estatística e sua associa？？o a níveis distintos de actividade física

the metabolic syndrome (ms) is considered as a cluster of cardiovascular risk factors. it is a particularly important infirmity which concerns the medical and scientific community at a worldwide level as it has been increasing gradually in children and as well as in adults, and is strongly associated with the development of risk increases of cardiovascular diseases and mortality. there is still no consensual definition about ms, cut-off values for every single indicator and unique statistical analysis strategies to deal with its results. although it is generally accepted that physical activity and physical exercise have benign impacts on ms prevention and treatment, it is not yet well demonstrated the precise dose-response relationship. the main purpose of the state-of-the-art summary is to revise the ms definition, criteria to classify the ms and the varieties of statistical analysis. in addition we shall focus on the relationship between physical activity and ms manifestations.
