Abstract

Introduction: Recent studies have identified that, since early age, sedentary lifestyle and the obesity are important factors to the development of cardiovascular complications, since early age and, also, at adulthood. However, the burden of both over cardiovascular system it is not clear, mainly during adolescence, which is characterized by fast and relevant modification in human organism. Objectives: To analyze, after a follow up of 12 months, (i) if physical activity and adiposity modification affect the cardiovascular system of adolescents, as well as, (ii) if these possible modifications in physical activity and body fatness are independently between them. Methods: Prospective study (cohort of 12 months) that will be carried out in Presidente Prudente, Brazil. Schools at central region of the city will be inserted at the sampling process. The sample will be composed of students with age ranging from 11 to 14 years-old. Hemodynamic variables (systolic and diastolic blood pressure and heart rate variability) will be assessed by specific devices. The measurements of the intima-media thickness and blood flow will be performed by Doppler ultrasonography. Anthropometry (weight, height, and trunk-height and waist-circumference) and body composition (Dual energy x ray absorptiometry [DEXA]) will be assessed. Physical activity will be assessed by pedometer. Blood measures (low density lipoprotein [LDL-C]; C reactive protein) will be performed at University laboratory. Several behaviors will be assessed by questionnaire (alcohol consumption, cigarette consumption, skipping meals and sleep quality). Possible findings: It is possible to identify the impact of physical activity and obesity over cardiovascular system of adolescents, as well to identify the existence of dependence between them. The findings will be important to identify the amount of physical activity (in number of steps, which is of easy understanding for general population) necessary to prevent elevated adiposity and to promote adequate cardiovascular health.
