Objective: To identify risk factors associated with obesity in gradeschoolers attended in a pediatric clinic and correlate them. Methods: This is a transversal and observational study with collection of data on physical activity, blood pressure levels of gradeschoolers and anthropometric data of the gradeschoolers and their parents in a pediatric clinic from september to december 2015. Children were included in the gradeschooler age from 5 to 12 years old. Results: There was a prevalence of 38% of overweight and 16% of obesity. About the blood pressure levels, 34% were at 50th percentile, 38% at 90th percentile, 16% at 95th percentile and 12% at 99th percentile of blood pressure. 86% were classified as active and 14% as inappropriately active. About the regular practice of physical activity, 30% practiced regular physical activity and 70% practiced irregularly. Conclusion: The prevalence of childhood obesity was 16% and 38% of overweight. There was no association between obesity, physical activity practices and BMI of the parents. However, it was found a strong relationship between obesity and increased blood pressure levels. The lifestyle changes to prevention and treatment of obesity are really important in preventing cardiovascular events in the future.
