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 Bogotá (Colombia) who were part of the FUPRECOL study (Asociación de la Fuerza Prensil con Manifestaciones Tempranas de Riesgo Cardiovascular en Niños y Adolescentes Colombianos - Association between prehensile force and early signs of cardiovascular risk in Colombian children and adolescents).
This was a cross-sectional study conducted among 5850 students aged 9-17.9 years old from Bogotá (Colombia). Body fat percentage was measured using foot-to-foot bioelectrical impedance (Tanita®, BF-689), by age and gender. Weight, height, waist circumference, and hip circumference were measured, and sexual maturity was self-staged. Percentiles (P3, P10, P25, P50, P75, P90 and P97) and centile curves were estimated using the LMS method (L [BoxCox curve], M [median curve] and S [variation coefficient curve]), by age and gender.
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 P90 were considered to have a high cardiovascular risk due to excess fat (boys > 23.428.3, girls > 31.0-34.1).
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.
身体成分分析是营养状况评估的基本组成部分。本研究的目的是通过生物电阻抗法确定来自波哥大（哥伦比亚）的儿童和青少年的体脂百分位数，这些儿童和青少年是FUPRECOL研究（哥伦比亚儿童和青少年握力与心血管疾病早期风险表现协会——哥伦比亚儿童和青少年握力与心血管风险早期迹象之间的关联）的一部分。
这是一项对来自波哥大（哥伦比亚）的5850名9至17.9岁学生进行的横断面研究。使用足对足生物电阻抗（Tanita®，BF - 689）按年龄和性别测量体脂百分比。测量体重、身高、腰围和臀围，并由受试者自行判断性成熟阶段。使用LMS方法（L[BoxCox曲线]、M[中位数曲线]和S[变异系数曲线]）按年龄和性别估计百分位数（P3、P10、P25、P50、P75、P90和P97）和百分位曲线。
纳入的受试者包括2526名儿童和3324名青少年。确定了按年龄和性别划分的体脂百分比和百分位曲线。在大多数年龄组中，女孩的值高于男孩。体脂值高于P90的参与者被认为因脂肪过多而具有较高的心血管疾病风险（男孩>23.4 - 28.3，女孩>31.0 - 34.1）。
本文给出了按年龄和性别使用生物电阻抗测量的体脂百分比百分位数，可作为评估营养状况和预测早年因脂肪过多导致心血管疾病风险的参考。
