[Lack of relationship of physical activity level with cardiovascular risk factors and metabolic syndrome in apparently healthy men]. / Falta de relación entre el nivel de actividad física con marcadores de riesgo cardiovascular y síndrome metabólico en hombres aparentemente sanos.

BACKGROUND: The World Health Report 2002 estimated that sedentary is one of the main 10 causes of morbidity and mortality and the proportion of people whose health is at risk due to sedentary life is approximately 60%. OBJECTIVE: To assess the relationship of the physical activity level with cardiovascular risk factors and metabolic syndrome in 61 healthy men. METHODS: The short version of the International Physical Activity Questionnaire (IPAQ) recommended by the World Health Organization was used as a valid measure to estimate two categories of physical activity, such as: low level (insufficient and sedentary) and vigorous level (moderate and very active). Cardiovascular risk factors and metabolic syndrome were defined according to criteria of the National Cholesterol Education Program of the United States and International Diabetes Federation respectively. Serum levels of C-reactive protein and ferritin were also measured, and insulin sensitivity was estimated by the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR). RESULTS: Mean age of study population was 47.1 ± 6.9 years. 17 participants (28%) had metabolic syndrome. There were no differences between the categories of low and vigorous level physical activity, or relationship with total physical activity (MET × week). No association was seen between low levels of physical activity and metabolic syndrome criteria. CONCLUSIONS: The high prevalence of physical inactivity found in study participants using the IPAQ questionnaire was not associated to cardiovascular risk factors and metabolic syndrome.

Antecedentes El Informe Mundial de la Salud de 2002 estimó que el sedentarismo es una de las principales diez causas de morbilidad y mortalidad y la proporción de las personas cuya salud está en riesgo debido a la vida sedentaria es de aproximadamente 60%.ObjetivoEvaluar la relación de el nivel de actividad física con factores de riesgo cardiovascular y el síndrome metabólico en 61 hombres sanos. Métodos La versión corta del cuestionario de la International Physical Activity Questionnaire (IPAQ), recomendado por la Organización Mundial de la Salud, fue utilizado como una medida válida para estimar dos categorías de actividad física, como son: nivel bajo (insuficiente y sedentarios) y nivel vigoroso (moderado y muy activa). Factores de riesgo cardiovascular y síndrome metabólico se definió de acuerdo con los criterios del National Cholesterol Education Program de los Estados Unidos y el International Diabetes Federation, respectivamente. Los niveles séricos de proteína C-reactiva y la ferritina también fueron medidos, y la sensibilidad a la insulina se calculó mediante la evaluación del modelo de la resistencia a la insulina (HOMA-IR).Resultados La media de edad de la población de estudio fue de 47.1±6.9 años. 17 participantes (28%) tuvieron síndrome metabólico. No hubo diferencias entre las categorías de actividad física nivel bajo y nivel vigoroso, o la relación con la actividad física total (MET×semana). No se observó asociación entre los niveles bajos de actividad física y los criterios de síndrome metabólico. Conclusiones La alta prevalencia de inactividad física en los participantes del estudio con el cuestionario IPAQ no se asoció a factores de riesgo cardiovascular y síndrome metabólico (AU)
