          Abstract

          RESUMEN El objetivo de esta investigación fue analizar las propiedades psicométricas propuestos por Moreno, Moreno y Cervelló (2007) para el cuestionario Medida de la Intencionalidad para ser Físicamente Activo (MIFA). La muestra total fue de 549 adolescentes mexicanos 256 mujeres y 293 hombres, con edades comprendidas entre 11-16 años (M = 12.91; DE = 0.49). La estructura factorial del cuestionario se analizó mediante análisis factoriales confirmatorios. Los análisis, muestran que una estructura unifactorial es viable y adecuada tanto para la muestra total (GFI = .999; RMSEA < .001; CFI = 1.000) como para las poblaciones de hombres (GFI = .991; RMSEA = .074; CFI = .995) y mujeres (GFI = .995; RMSEA = .032; CFI = .999). La estructura unifactorial, atendiendo a criterios estadísticos y sustantivos, ha mostrado adecuados indicadores de ajuste de fiabilidad y validez. Por otro lado, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes de acuerdo al género; sin embargo, existen diferencias entre hombres y mujeres para la media de intencionalidad para ser físicamente activo. En conclusión, el MIFA-M puede ser una herramienta útil para avanzar en el estudio de los factores que afectan a la práctica de actividad física.

          ABSTRACT The aim of this research was to analyze the psychometric properties proposed by Moreno et al. (2007) for the Measurement of Intention to be Physically Active (MIFA) questionnaire. The total sample has been composed by 549 Mexican adolescents, 256 women and 293 mean, with ages from 11 to 16 years (M = 12.91, SD = 0.49). The factor structure of questionnaire has been analized through the confirmatory factor analysis. This analysis shows that a unifactorial structure is viable and adequate for the total sample (GFI = .999; RMSEA < .001; CFI = 1.000) and the populations of men (GFI = .991; RMSEA = .074; CFI = .995) and women (GFI = .995; RMSEA = .032; CFI = .999). The unifactorial structure, according to statistical and substantive criteria, has shown adequate indicators of reliability and validity adjustment. On the other hand, the factorial structure, the factorial loads and the intercepts are considered invariant according to gender; however, there are differences between men and women for the average intentionality of being physically active. In conclusion, the MIFA-M can be a useful tool to advance in the study of the factors that affect the practice of physical activity.

          RESUMO O objetivo do presente estudo instrumental foi analisar a composição e invariância fatorial por gênero do questionário Medida de Intencionalidade a ser Fisicamente Ativa proposto por Moreno et al. (2007) adaptado ao contexto mexicano (MIFA-M) em adolescentes mexicanos. Um total de 549 adolescentes mexicanos, 256 mulheres e 293 homens, com idades entre 11 e 16 anos (M = 12.91; DP = .49) completaram o questionário MIFA-M A estrutura fatorial do questionário foi analisada por análises fatoriais confirmatórias. Os resultados mostraram que uma estrutura unifatorial é viável e adequada tanto para a amostra total (GFI = .999; RMSEA < .001; CFI = 1.000) quanto para as populações de homens (GFI = .991; RMSEA = .074; CFI = .995) e mulheres. Com base em critérios estatísticos e substantivos, a estrutura unifatorial apresentou indicadores adequados de confiabilidade e validade. Além disso, a estrutura fatorial, as cargas fatoriais e os interceptos eram invariantes de acordo com o gênero. Maiores valores de intenção de ser fisicamente ativo em homens do que em mulheres foram encontrados. Maiores valores de intenção de ser fisicamente ativo em homens do que em mulheres foram encontrados. Em conclusão, o MIFA-M é um instrumento útil para avaliar a intenção de ser fisicamente ativo em adolescentes mexicanos.

          Long-term health benefits of physical activity – a systematic review of longitudinal studies

          Background The treatment of noncommunicable diseases (NCD), like coronary heart disease or type 2 diabetes mellitus, causes rising costs for the health system. Physical activity is supposed to reduce the risk for these diseases. Results of cross-sectional studies showed that physical activity is associated with better health, and that physical activity could prevent the development of these diseases. The purpose of this review is to summarize existing evidence for the long-term (>5 years) relationship between physical activity and weight gain, obesity, coronary heart disease, type 2 diabetes mellitus, Alzheimer’s disease and dementia. Methods Fifteen longitudinal studies with at least 5-year follow up times and a total of 288,724 subjects (>500 participants in each study), aged between 18 and 85 years, were identified using digital databases. Only studies published in English, about healthy adults at baseline, intentional physical activity and the listed NCDs were included. Results The results of these studies show that physical activity appears to have a positive long-term influence on all selected diseases. Conclusions This review revealed a paucity of long-term studies on the relationship between physical activity and the incidence of NCD.
