--- Introduction: Physical inactivity is the fourth most important risk factor of mortality worldwide, while overweight and obesity are the fifth leading risk factor for deaths globally. In 2008 in Peru, 7.8% of all children between 5 and 9 years old were overweight. Having an overweight in childhood creates a risk of heart disease, metabolic syndrome, stroke, some kind of cancers, diabetes and eating disorders in adulthood. Objectives: To determine the relationship between physical activity, body mass index and body fat percentage in children 8-11 years old of a school in Comas’s district. Design: Quantitative Approach observational, descriptive, cross and cross-association type. Location: School N° 2016 “Francisco Bolognesi“ of the district of Comas. Participants: 128 children between 8 and 11 years old. Interventions: Weight, height and Body Mass Index (BMI) was evaluated by Anthro Plus Who, while the Percentage of Body Fat (PBF) was evaluated by measuring the thickness of four subcutaneous folds with a caliper and using the Westrate and Deurenberg formula. Physical activity (PA) was assessed with a questionnaire from the Institute of Nutrition and Food Technology, Chile. Main outcome measures: Association by Chi test of physical activity with the variables body mass index and percentage of body fat. Results: Children with overweight and obesity, according to BMI, were 25.8 and 27.3%, respectively. Meanwhile, overweight children and obesity, according to PBF, were 29.7 and 25%, respectively. 58.6% of the students surveyed were considered sedentary, with no significant difference in sex. Chi2 test showed the relationship between PA and BMI (Chi 2 = 29.7 and OR = 8.4 (3.7-18.9)) between the PA and the PBF (Chi 2 = 37.4 and OR = 11.6 (5.0-27.0)) between the BMI and PBF (Chi 2 = 84.3 and OR = 95.4 (28.6-318.1)). Conclusions: 53.1% of the students showed some degree of overweight according to the Body Mass Index, while 54.7% of children had body fat excess. In addition, 58.6% of students were considered sedentary. Keywords: Body Mass Index, Body Fat Percentage, Physical Activity.
