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.

ABSTRACT Purpose: to verify hearing difficulties related to everyday listening situations self-reported by normally-hearing adults. Methods: a cross-sectional observational study in which adult ...individuals with clinically normal hearing, verified through audiometry and tympanometry, were included. The participants answered the Brazilian Portuguese version of the Speech, Spatial and Qualities of Hearing Scale (SSQ) questionnaire. Statistical analysis comprised descriptive and Spearman’s correlation test with a significance level of 5%. Results: the sample consisted of 28 participants, aged between 20 and 44 years. The median SSQ score was 8.75, in the Hearing to Speech domain, 8.11, in the Spatial Hearing domain, and 8.91, in the Quality-of-Hearing domain. There was an association between the participant's age and the score on five questions, demonstrating less self-reported difficulty as age increased. Conclusion: difficulties in everyday listening situations, self-reported by normally-hearing adults, participating in this study, were more related to situations with competitive noise and listening effort.
RESUMO Objetivo: verificar as dificuldades auditivas relacionadas a situações cotidianas de escuta autorrelatadas por adultos normo-ouvintes. Métodos: trata-se de um estudo observacional transversal. Foram incluídos indivíduos adultos com limiares auditivos normais, verificados por meio de audiometria e timpanometria. Os participantes responderam à versão no português brasileiro do questionário Speech, Spatial and Qualities of Hearing Scale (SSQ). Os resultados foram analisados descritiva e estatisticamente. A análise estatística compreendeu teste descritivo e de correlação de Spearman com nível de significância de 5%. Resultados: a amostra foi composta por 28 participantes, com idades entre 20 e 44 anos. A mediana da pontuação no SSQ foi de 8,75 pontos no domínio Audição para a Fala; 8,11 no domínio Audição Espacial e 8,91 pontos no domínio Qualidade da Audição. Observou-se associação entre a idade do participante e a pontuação em cinco questões, demonstrando menor dificuldade autorrelatada conforme o aumento da idade. Conclusão: as dificuldades em situações cotidianas de escuta autorrelatadas pelos adultos normo-ouvintes participantes desse estudo foram mais relacionadas a situações com ruído competitivo e esforço de escuta.
