<p>Os objetivos do estudo foram traduzir para o idioma português, realizar a adaptação transcultural e identificar as propriedades psicométricas do <em>Behavioral Regulation in Exercise Questionnaire – Version 3</em> (<em>BREQ-3</em>) para uso em adultos brasileiros. O questionário original foi traduzido de acordo com recomendações internacionais. Um comitê de juízes foi formado para analisar as versões traduzidas do questionário. O comitê utilizou como critério de análise as equivalências semântica, idiomática, cultural e conceitual. A versão final do questionário traduzido foi administrada em uma amostra de 1041 adultos (55% homens) praticantes de exercício físico da área metropolitana da cidade de Londrina, Paraná com idades ≥ 18 anos. Para identificar as propriedades psicométricas iniciais foi realizada análise fatorial exploratória e, na sequência, análise fatorial confirmatória. Para análise da consistência interna de cada fator associado à motivação para a prática de exercício físico foi empregado coeficiente alfa de <em>Cronbach</em>. Após discretas modificações apontadas no processo de tradução, o comitê de juízes considerou que a versão para o idioma português do <em>BREQ-3</em> apresentou equivalências semântica, idiomática, cultural e conceitual. A análise fatorial confirmou a estrutura de seis fatores originalmente proposta, mediante indicadores estatísticos equivalentes à χ<sup>2</sup>/gl = 1,91, ao GFI = 0,938, AGFI = 0,954 e RMSR = 0,059 (IC<sub>95%</sub> 0,051-0,069). O alfa de <em>Cronbach</em> apresentou coeficientes entre 0,67 e 0,87. Concluindo, a tradução, a adaptação transcultural e as qualidades psicométricas do <em>BREQ-3</em> foram satisfatórias, o que viabiliza sua aplicação em futuros estudos no Brasil.</p>
Introduction: The Behavioral Regulation in Sport Questionnaire (BRSQ) was originally proposed in English in order to identify sports motivation regulations according to the self-determination theory. Objectives: To translate into Portuguese, to perform cross-cultural adaptation, and to examine the psychometric properties of the BRSQ in a sample of young Brazilian athletes. Methods: The original version was translated according to international recommendations. A panel of judges analyzed the translated versions of the questionnaire, using semantic, idiomatic, cultural and conceptual equivalence as analysis criteria. The final version of the translated questionnaire was administered in a sample of 1217 young athletes (410 girls and 807 boys) aged 12 to 17 years. An exploratory factor analysis was carried out to identify initial psychometric properties, followed by a confirmatory factor analysis. Cronbach's alpha coefficient was used to assess the internal consistency of each factor associated with the BRSQ. Results: After minor changes identified in the translation process, the panel of judges was of the opinion that the Portuguese version of the BRSQ had semantic, idiomatic, cultural and conceptual equivalence. The factor analysis confirmed the structure of the eight factors proposed originally, through the statistical indicators χ2/gl = 1.87, CFI = 0.940, GFI = 0.945, AGFI = 0.958 and RMSR = 0.052 (95% CI 0.043 – 0.062). The Cronbach's alpha ranged from 0.71 to 0.85. Conclusions: Translation, cross-cultural adaptation and analysis of the psychometric qualities of the BRSQ were satisfactory, facilitating its application in future studies involving young athletes in Brazil. Level of Evidence III; Retrospective comparative study.
Identify nutritional inadequacies in specific segments of the child population may offer subsidies for public health intervention. The aim of this study was to assess the anthropometric nutritional status in a sample of children from a city in the southern region of Brazil. The sample comprised 23 thousand subjects of both sexes who ranged in age from 5 to 10 years. The anthropometric nutritional status was identified by height and body weight. The comparisons were based on the corresponding distributions of percentiles of the Word Health Organizations, 2007 reference. Analysis of results indicated that the distributions of percentiles of the height and BMI values in both sexes were statistically different of those from WHO-2007 reference. The data showed high proportion of children with low height (< 10 Percentile) and indication of excess of body weight (> 90 Percentile). The nutritional impairment translated by the high proportion of low height and excess body weight alerts to the need to implement public policies for healthy eating practices and physical activity.Keywords: Nutritional Status. Growth. Malnutrition. Height. Obesity. Resumo Identificar inadequações nutricionais em segmentos específicos da população infantil pode oferecer subsídios para intervenção em saúde pública. O estudo analisou estado nutricional antropométrico em amostra de crianças escolares de uma cidade da região sul do Brasil. A amostra foi constituída por 23 mil sujeitos de ambos os sexos, com idade entre 5 e 10 anos. O estado nutricional antropométrico foi identificado mediante medidas de estatura e peso corporal. As comparações estatísticas foram estabelecidas com base nas correspondentes distribuições
