Resumo: | Introduction: Accurate measures of physical activity to establish dose-response relationship in health outcomes are still controversial. Scales that estimate caloric expenditure are proposed with a view to categorizing the phenomenon globally. Objective: To carry out a factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese, and propose a new adapted version for the Brazilian elderly community. Methods: Participants were elderly female members of the community, without any distinction in terms of ethnic group and/or social class, who frequented extension projects of two higher education institutions. Those with cognitive impairments; dependence on walking aids; musculoskeletal pain in the last two weeks and neurological diseases were excluded from the study. All participants answered the questionnaire with sociodemographic and clinical data and the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese version. We determined whether each activity had been undertaken by the participants and the average number of times it was performed over the last two weeks, considering average time, in minutes, on each occasion. Each activity was considered a single item and energy expenditure was calculated according to the authors’ instructions. We used factor analysis with Varimax orthogonal rotation, excluding items whose variance was equal to zero. Correlation between items was determined using the Pearson correlation matrix. Internal consistency between items, before and after the factor analysis, was verified using Cronbach’s α coefficient. 5% significance level. Results: Participants were 220 women (70.8 ± 5.9 years). The factor analysis resulted in 10 components, which explained, in total, 61.87% of the variance of the total score on the scale. Each component was composed of one, two or three aggregate items. Internal consistency by Cronbach’s α coefficient was 0.30. Conclusion: The factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese- has shown a new range with 10 components, which explained, in total, more than 60% of the variance of the total score on the scale, yet with low internal consistency. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference ‘‘gold’’ standard. |

Escalas que estimam o gasto calórico são propostas visando categorizar o fenômeno de forma global. Objetivo: Realizar a análise fatorial da estrutura do Minnesota Leisure Time Activities Questionnaire - português-Brasil e propor uma nova versão adaptada aos idosos comunitários brasileiros. Métodos: Participaram idosas, residentes da comunidade, sem distinção de raça e/ou classe social e frequentadoras de projetos de extensão de duas escolas de ensino superior. Excluíram-se aquelas com alterações cognitivas, marcha dependente, dores musculoesqueléticas nas últimas duas semanas e doenças neurológicas. Todas responderam ao questionário com dados sócio-clínico-demográficos e ao Minnesota Leisure Time Activities Questionnaire - versão português-Brasil. Foi identificado se cada atividade tinha sido realizada e o número médio de vezes nas últimas duas semanas, considerando tempo médio, em minutos, em cada ocasião. Cada atividade foi considerada como um item e o gasto energético foi calculado de acordo com as instruções dos autores. Utilizou-se a análise fatorial com rotação ortogonal Varimax excluindo os itens cuja variância era igual a zero. A correlação entre os itens foi realizada pela matriz de correlação de Pearson. A consistência interna entre os itens, antes e depois da análise fatorial foi realizada através do coeficiente α de Cronbach. Nível de significância de 5%. Resultados: Participaram 220 mulheres (70,8 ± 5,9 anos). A análise fatorial resultou em 10 componentes que explicaram no total 61,87% da variância da pontuação total na escala. Cada componente era composto por um, dois ou três itens agregados. A consistência interna pelo coeficiente α de Cronbach foi de 0,30. Conclusão: A análise fatorial da estrutura do Minnesota Leisure Time Activities Questionnaire - português-Brasil apresentou uma nova escala com 10 componentes que explicou no total mais de 60% da variância da pontuação total na escala, porém com uma baixa consistência interna. Nível de Evidência Nível III; Estudo de pacientes não consecutivos; sem padrão de referência “ouro” aplicado uniformemente.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilEEF - DEPARTAMENTO DE FISIOTERAPIARevista Brasileira de Medicina do EsporteEnvelhecimentoExercícios físicosQuestionáriosAgedPhysical activityQuestionnaireFactor analysys of the Minnesota Leisure Time Activities Questionnaire - brazilian portugueseAnálise fatorial do Minnesota Leisure Time Activities Questionnaire - português-Brasilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/rbme/a/Jzqrp3xyXNxWvfwhdR63qNz/?lang=enLygia Paccini LustosaSilvia Lanziotti Azevedo da SilvaTaís Almeida MarraJoão Marcos Domingues DiasLeani Souza Máximo PereiraRosângela Correa Diasapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/46438/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALFactor analysys of the Minnesota Leisure Time Activities Questionnaire.pdfFactor analysys of the Minnesota Leisure Time Activities Questionnaire.pdfapplication/pdf106737https://repositorio.ufmg.br/bitstream/1843/46438/2/Factor%20analysys%20of%20the%20Minnesota%20Leisure%20Time%20Activities%20Questionnaire.pdf7d8f52736afb80c5501ae503cd9f22dbMD521843/464382022-10-20 11:13:52.03oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-10-20T14:13:52Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |

Introduction: Accurate measures of physical activity to establish dose-response relationship in health outcomes are still controversial. Scales that estimate caloric expenditure are proposed with a view to categorizing the phenomenon globally. Objective: To carry out a factor analysis of the structure of the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese, and propose a new adapted version for the Brazilian elderly community. Methods: Participants were elderly female members of the community, without any distinction in terms of ethnic group and/or social class, who frequented extension projects of two higher education institutions. Those with cognitive impairments; dependence on walking aids; musculoskeletal pain in the last two weeks and neurological diseases were excluded from the study. All participants answered the questionnaire with sociodemographic and clinical data and the Minnesota Leisure Time Activities Questionnaire - Brazilian Portuguese version. We determined whether each activity had been undertaken by the participants and the average number of times it was performed over the last two weeks, considering average time, in minutes, on each occasion. Each activity was considered a single item and energy expenditure was calculated according to the authors’ instructions. We used factor analysis with Varimax orthogonal rotation, excluding items whose variance was equal to zero. Correlation between items was determined using the Pearson correlation matrix. Internal consistency between items, before and after the factor analysis, was verified using Cronbach’s α coefficient. 5% significance level. Results: Participants were 220 women (70.8 ± 5.9 years). The factor analysis resulted in 10 components, which explained, in total, 61.87% of the variance of the total score on the scale. Each component was composed of one, two or three aggregate items.
