ABSTRACT
Objetivo Revisar, de forma sistemática, a literatura sobre a prevalência e fatores associados ao nível de atividade física e ao estado nutricional de crianças brasileiras. Método Foram selecionadas as bases de dados eletrônicas MEDLINE via Pubmed, Scielo, Web of Science e SCOPUS. A estratégia de busca incluiu os descritores propostos no Medical Subject Headings (MeSH): "Motor Activity", "Activities, "Nutritional Status", "Overweight", "Obesity", "Body Mass Index", "Child", "Brazil". Resultados A busca permitiu identificar 141 artigos, sendo que 16 estudos foram considerados potencialmente relevantes e foram incluídos na revisão. Conclusão Estudos com as temáticas: estado nutricional e nível de atividade física em crianças brasileiras ainda são escassos, mas vem aumentando nos últimos anos, especialmente aqueles com delineamentos transversais, bem como a utilização de questionários para mensuração da atividade física e do IMC para o estado nutricional ainda é amplamente utilizada. Além disso, nos estudos analisados a quantidade de horas atribuídas em comportamentos sedentários como: televisão, vídeo-game e computador foi superior a 2 horas diárias.(AU)
Objective To systematically review the literature on the prevalence and the factors associated with physical activity level and nutritional status of Brazilian children. Methods The electronic database MEDLINE (via PubMed), SciELO, SCOPUS and Web of Science were selected. The search strategy included the descriptors proposed in the Medical Subject Headings (MeSH): "Motor Activity", "Activities", "Nutritional Status", "Overweight", "Obesity", "Body Mass Index", "Child", "Brazil". Results The search allowed the identification of 141 articles, of which 16 studies were considered potentially relevant and were included in the review. Conclusions Studies about nutritional status and physical activity levels in Brazilian children are still scarce, but the work on this has increased in recent years, especially those that use cross designs, as well as questionnaires to measure physical activity; BMI for nutritional status is still widely used. Furthermore, studies that analyzed the amount of hours designated to sedentary behaviors such as watching TV, playing video-games and using the computer, found that these activities took more than two hours every day.(AU)

Given the results, it is possible to highlight that officers who work rotating shifts or during the night are exposed to worse sleep quality, greater dissatisfaction with work, low levels of alert, breathing problems and snoring, as well as higher rates of injury and degraded driving performance.
ABSTRACT
La producción académica ha aumentado en el área de la salud, exigiendo cada vez más calidad en las publicaciones de gran impacto. Una de las formas de considerar la calidad es por medio de procedimientos que aumentan la consistencia del análisis de los datos, como la confiabilidad, que dependiendo del tipo de datos, puede ser evaluada por diferentes coeficientes, en especial el coeficiente alfa. Basados en lo anterior, la presente revisión reúne sistemáticamente artículos científicos producidos en los últimos cinco años, que de manera metodológica hicieron uso psicométrico del coeficiente α como un estimador de consistencia interna y de confiabilidad en procesos de construcción, adaptación y validación de instrumentos. La identificación de los estudios fue realizada sistemáticamente en las bases de datos Biomed Central Journals, Google Scholar, Web of Science, Wiley Online Library, Medline via Pubmed, Scielo, Scopus, Journals@Ovid, BMJ y Springer por medio del Portal de Periódicos CAPES, utilizando criterios de inclusión y exclusión. El análisis de los datos fue realizado por medio de triangulación, análisis de contenido y análisis descriptivo. Se obtuvo que la mayoría de los estudios fueron realizados principalmente en Irán (f=3), España (f=2) y Brasil (f=2), estos estudios tuvieron como objetivo testar las propiedades psicométricas de instrumentos, siendo que ocho estudios utilizaron el coeficiente α para evaluar la confiabilidad y nueve para evaluar la consistencia interna. Todos los estudios fueron clasificados como investigaciones metodológicas al analizar sus objetivos. Adicionalmente, cuatro estudios también fueron clasificados como correlacionales y uno como descriptivo-correlacional. Se puede concluir que a pesar de que el coeficiente α es ampliamente utilizado como uno de los principales parámetros para la evaluación de consistencia interna de instrumentos de medición del tipo cuestionario en el área de ciencias de la salud.
Academic production has increased in the area of health, increasingly demanding high quality in publications of great impact. One of the ways to consider quality is through methods that increase the consistency of data analysis, such as reliability which, depending on the type of data, can be evaluated by different coefficients, especially the alpha coefficient. Based on this, the present review systematically gathers scientific articles produced in the last five years, which in a methodological manner gave the α coefficient psychometric use as an estimator of internal consistency and reliability in the processes of construction, adaptation and validation of instruments. The identification of the studies was conducted systematically in the databases BioMed Central Journals, Web of Science, Wiley Online Library, Medline, SciELO, Scopus, Journals@Ovid, BMJ and Springer, using inclusion and exclusion criteria. Data analyses were performed by means of triangulation, content analysis and descriptive analysis. It was found that most studies were conducted in Iran (f=3), Spain (f=2) and Brazil (f=2). These studies aimed to test the psychometric properties of instruments, with eight studies using the α coefficient to assess reliability and nine for assessing internal consistency. All studies were classified as methodological research when their objectives were analyzed. In addition, four studies were also classified as correlational and one as descriptive-correlational. It can be concluded that though the α coefficient is widely used as one of the main parameters for assessing internal consistency of questionnaires in health sciences, its use as an estimator of trust of the methodology used and internal consistency has some critiques that should be considered.

ABSTRACT
O objetivo desse estudo foi verificar a associação entre as aptidões físicas e a ocorrência de quedas em idosos praticantes de exercícios físicos. Selecionaram-se, de forma intencional, 230 idosos (60 anos ou mais) praticantes de exercícios físicos. Foram coletados dados sociodemográficos, ocorrência de quedas no último ano e as aptidões físicas que envolvem a avaliação dos membros inferiores (força dos membros inferiores, flexibilidade dos membros inferiores, agilidade e o equilíbrio dinâmico, e resistência aeróbica) da bateria de teste para idosos Senior Fitness Test. A análise dos dados deu-se através de estatística descritiva e inferencial (teste Qui-Quadrado e Regressão Logística Binária), com nível de significância de p=0,05. Entre os resultados, destaca-se que a ocorrência de quedas no último ano entre os idosos foi de 22,2%. De acordo com a razão de odds, a chance de sofrer quedas foi 2,66 vezes maior nos idosos com classificação "Ruim" da força de membros inferiores (p= 0,022) quando comparados aqueles cuja classificação foi boa. Conclui-se que a falta de força nos membros inferiores parece ser um importante fator de risco para a ocorrência de quedas entre idosos praticantes de exercícios físicos. Assim, programas de exercícios físicos devem enfatizar o fortalecimento muscular, especialmente dos membros inferiores, para que se previnam as quedas e suas consequências nessa população.
The aim of this study was to investigate the association between physical fitness and the occurrence of falls in elderly practitioners of exercise. It was selected intentionally 230 elderly (60 years or more) practitioners of exercise. We collected demographic data, occurrence of falls in the last year and the physical fitness that involve the assessment of the lower limbs (strength of lower limbs, lower limbs flexibility, agility and dynamic balance, resistance aerobic) of the test battery for older Senior Fitness Test. Analysis of data was by descriptive and inferential statistics (Chi-Square and Binary Logistic Regression) with significance level of p = 0,05. Among the results, it is emphasized that the incidence of falls in the last year among the elderly was 22,2%. According to the odds ratios, the chance of falls was 2,66 times higher in the elderly rated "Poor" of lower limb strength (p = 0,022) when compared with those whose rating was good. It is concluded that the lack of strength of the lower limbs seems to be an important risk factor for the occurrence of falls among elderly practitioners of exercise. Thus, physical exercise programs should emphasize muscle strengthening, especially of the lower limbs, in order to prevent falls and their consequences in this population.
