Measuring weight is difficult to be carried out in bedridden people, with physical deformity or in emergency units. Under these circumstances, one option is to estimate the weight.
The aim of this study is to propose and validate equations for estimating the weight of Brazilian adolescents based on anthropometric variables related to body weight.
The study was developed based on a database created from data collection of a primary project, which had information from 662 Brazilian adolescents (10 to 19 years old). Based on the variables sex, age (days), weight (kg), height (m) and neck circumference (NC) (cm), equations for estimating weight of adolescents were proposed. The formulas were proposed after performing multiple linear regression models and subsequently tested and validated using appropriate statistical tests, considering 99% confidence.
Two formulas were generated, the "Rucco Formulas-Adolescents", one for girls: -131.63091 + (0.00209 × A) + (37.57813 × H) + (3.71482 x NC) and another for boys: - 15.2854 + (-0.00414 × A)+ (14.30315 × H2)+ (0.04888 x NC2). Statistical test (R2) indicated that the proposed formulas are suitable for estimating weight. Low values of REQM and high values of CCI (> 0.8) also reinforce the quality of the proposed formulas.
The current weight of adolescents can be estimated with adequate accuracy and precision using sex-specific "Rucco Formulas-Adolescents", generated from regression models using only three predictor variables.
对于卧床不起、身体畸形或在急救单位的人来说，测量体重是困难的。在这些情况下，一种选择是估计体重。
本研究旨在提出并验证基于与体重相关的人体测量变量来估计巴西青少年体重的方程。
该研究基于从主要项目的数据收集创建的数据库进行，该数据库包含 662 名巴西青少年（10 至 19 岁）的信息。基于性别、年龄（天）、体重（kg）、身高（m）和颈围（NC）（cm）等变量，提出了估计青少年体重的方程。在进行多元线性回归模型后提出了公式，然后使用适当的统计检验进行测试和验证，置信度为 99%。
生成了两个公式，即“Rucco 公式-青少年”，一个适用于女孩：-131.63091 + (0.00209 × A) + (37.57813 × H) + (3.71482 x NC)，另一个适用于男孩：-15.2854 + (-0.00414 × A) + (14.30315 × H2) + (0.04888 x NC2)。统计检验（R2）表明，所提出的公式适用于估计体重。低的 REQM 值和高的 CCI 值（> 0.8）也增强了所提出公式的质量。
使用性别特异性的“Rucco 公式-青少年”，仅使用三个预测变量生成回归模型，可以以足够的准确性和精度估计青少年的当前体重。
