Fit, Healthy and Smart Preschool Children: PREFIT-Chile

Introduction: Investigating the interrelationship between physical condition, non-invasive health markers and executive function in preschoolers, is based on the current health and cognitive development situation of this population, especially the low socioeconomic level. National figures estimate that the prevalence of overweight / obesity in the preschool population reaches 53.6%, exposing not only the development of cardiovascular and metabolic diseases, but also affect cognitive potential. Physical condition is a powerful health marker independent of nutritional status. Its evaluation together with the evaluation of non-invasive health markers and executive function in preschoolers inside educational establishments is essential to investigate alterations at an early age that could be prevented with adequate interventions in schools. However, to achieve this, valid, reliable and comparable tools are needed internationally. Objective: to analyze the factors that affect the configuration of a diagnostic model which includes the physical fitness and physical activity levels, motor development, non-invasive risk factors and neuropsychological development in preschoolers. Methods: Observational study, case only, cross sectional. Enrollment 544 preschool child 4 to 5 years old. Primary Outcome is Physical fitness to "Prefit Battery", Secondary outcome non-invasive risk factors (Blood pressure, BMI, Waist circumference, neck circumference) Physical activity, Motor skills and Neuropsychological development. expected results: Determine the degree of association of physical fitness with non-invasive risk factors and neuropsychological development in preschoolers, determine the influence that physical activity level and motor development have on physical fitness and development a diagnostic model which includes the physical fitness and physical activity levels, motor development, non-invasive risk factors and neuropsychological development in Chilean preschoolers.
