Objective: To determine the ratio of the thickness of epicardial adipose tissue (EAT) with nutritional status (obesity, overweight and normal weight) in children and adolescents. Methods: Observational, analytical and cross-sectional study. Fifty-three children and adolescents from 6 to 18 years old were included, distributed according to body mass index (BMI) in obese, overweight and normal weight. Anthropometric measures and blood pressure (BP) were taken. TAE thickness was measured by two-dimensional echocardiography.
