Objective. The analysis of body composition is a fundamental part of nutritional status assessment. The objective of this study was to establish body fat percentiles by bioelectrical impedance in children and adolescents from Bogota (Colombia) who were part of the FUPRECOL study (Asociacion de la Fuerza Prensil con Manifestaciones Tempranas de Riesgo Cardiovascular en Ninos y Adolescentes Colombianos - Association between prehensile force and early signs of cardiovascular risk in Colombian children and adolescents).Methods. This was a cross-sectional study conducted among 5850 students aged 9-17.9 years old from Bogota (Colombia). Body fat percentage was measured using foot-to-foot bioelectrical impedance (Tanita (R), BF-689), by age and gender. Weight, height, waist circumference, and hip circumference were measured, and sexual maturity was self-staged. Percentiles (P-3, P-10, P-25, P-50, P-75, P-90 and P-97) and centile curves were estimated using the LMS method (L [Box-Cox curve], M [median curve] and S [variation coefficient curve]), by age and gender.Results. Subjects included were 2526 children and 3324 adolescents. Body fat percentages and centile curves by age and gender were established. For most age groups, values resulted higher among girls than boys. Participants with values above P-90 were considered to have a high cardiovascular risk due to excess fat (boys > 23.4-28.3, girls > 31.0-34.1).Conclusions. Body fat percentage percentiles measured using bioelectrical impedance by age and gender are presented here and may be used as reference to assess nutritional status and to predict cardiovascular risk due to excess fat at an early age.
