Atividade física, ajuste à prótese e condição de saúde de pessoas com amputação de membro inferior / Physical activity, adjustment to the prosthesis and health condition of people with lower limb amputation

Objetivo: Relacionar atividade física, características demográficas e clínicas, ajuste à prótese e condições de saúde relacionada à qualidade de vida de adultos com amputações de membro inferior. Método: Participaram do estudo 70 indivíduos com amputações de membro inferior de ambos os sexos. Os dados foram coletados por meio de ficha para caracterização dos participantes, do Physical Activity Scale for Individual with Physical Disabilities (PASIPD), da Trinity Amputation and Prosthesis Experience Scales­Revised (TAPES-R) e do Short Form Health Survey (SF-12). Os dados foram analisados por meio de estatística descritiva e inferencial visando correlações, comparações e associações. Foi adotado p menor ou igual a 0,05. Resultados: Os resultados demonstraram que os participantes tiveram gasto energético de 26,93 MET h/d e maiores médias de condições de Saúde Relacionado à Qualidade de Vida no domínio saúde mental, ainda apresentaram maiores médias relacionados ao Ajuste à Prótese no domínio Social (3,56) com Grau de Ajuste acima da média (6,42). Conclusão: Os participantes do estudo apresentaram bom nível de atividade física, bom ajuste à prótese, boa saúde física e mental, melhor adaptação à amputação e participação. Além disso, também foi observado uma pior relação na adaptação entre pessoas com amputação acima do joelho, quando comparadas às amputações abaixo do joelho.

Objective: To relate physical activity, demographic, and clinical characteristics, fit to the prosthesis and health conditions related to the quality of life of adults with lower limb amputations. Method: 70 individuals with lower limb amputations of both sexes participated in the study. Data were collected using a form to characterize the participants, the Physical Activity Scale for Individual with Physical Disabilities (PASIPD), the Trinity Amputation and Prosthesis Experience Scales­Revised (TAPES-R) and the Short Form Health Survey (SF-12). Data were analyzed using descriptive and inferential statistics aiming at correlations, comparisons, and associations. A p lower than or equal to 0.05 was adapted. Results: The results showed that the participants had an energy expenditure of 26.93 MET h/d and higher averages of Health Conditions Related to Quality of Life in the mental health domain, they still had higher averages related to Prosthesis Fit in the Social domain (3.56) with Adjustment Degree above average (6.42). Conclusion: Study participants had a good level of physical activity, good fit to the prosthesis, good physical and mental health, better adaptation to the amputation and participation. In addition, a worse relationship was observed in the adaptation between people with amputations above the knee, when compared to amputations below the knee.

Prevalence and factors associated with physical activity in socially vulnerable children / Prevalência e fatores associados à atividade física das crianças em vulnerabilidade social / Prevalencia y factores asociados a la actividad física de los niños en vulnerabilidad social

ABSTRACT Introduction: Although the benefits of physical activity are widely recognized, insufficient levels have been identified among young people, especially those experiencing social vulnerability. Therefore, there is an ongoing search for health incentive strategies, especially in the early stages of life, aimed at reversing this situation. Objective: Investigate the prevalence of physical activity, weight status and motivation to participate in sports among socially vulnerable children who are participating in social projects of the state of Santa Catarina focused on sports, and compare these results according to age and sex. Methods: This is a cross-sectional descriptive study, composed of 3066 children aged seven to 11 years. Results: The study was made up of "active" and "moderately active" children of "normal weight", considering the domains of motivation to participate in physical activities and sports: pleasure, physical fitness, technical competence, general affiliation, specific affiliation and "very important" status and emotions and competition, "important". Accordingly, girls tend to be more "moderately active," "overweight" and "obese" and to regard technical competence as an "important" motivational domain for physical activity when compared to boys. Participants aged 10 to 11 years were more "very active", were more "overweight" and "obese" and considered specific affiliation more "totally important" when compared to younger participants. Conclusion: The participants of social sports projects of this sample demonstrated a level of physical activity and weight status within recommended levels, and were motivated to participate in sports in most of the domains observed.

RESUMO Introdução: Apesar de os benefícios da prática de atividade física serem amplamente reconhecidos, níveis insuficientes são constatados entre jovens, especialmente, aqueles em vulnerabilidade social. Assim, buscam-se estratégias de incentivo à saúde, especialmente, nas fases iniciais da vida, visando a reversão desse quadro. Objetivo: Investigar a prevalência da atividade física, status de peso e motivação para a prática esportiva das crianças em situação de vulnerabilidade social, participantes de projetos sociais na área esportiva do estado de Santa Catarina e comparar tais resultados de acordo com a idade e sexo. Métodos: Trata-se de um estudo transversal descritivo, composto por 3066 crianças de sete a 11 anos. Resultados: Composto por crianças "ativas" e "moderadamente ativas", com "peso normal", considerando-se os domínios motivacionais para a prática de atividades físicas e esportivas: prazer, condição física, competência técnica, afiliação geral, afiliação específica e status "muito importante" e emoções e competição, "importante". Desta forma, as meninas tendem a ser mais "moderadamente ativas", a apresentar "sobrepeso" e "obesidade" e a considerar a competência técnica como domínio motivacional "importante" à prática de atividade física quando comparadas aos meninos. Os participantes com 10 a 11 anos eram mais "muito ativos", apresentaram mais "sobrepeso" e "obesidade" e consideraram a afiliação específica mais "totalmente importante" quando comparados aos mais novos. Conclusão: Os participantes dos projetos sociais esportivos dessa amostra demonstraram um nível de atividade física dentro das recomendações, assim como o status de peso, sendo motivados à prática esportiva na maior parte dos domínios observados. Nível de evidência III; Estudos diagnósticos - Investigação de um exame para diagnóstico.

[Estimators of internal consistency in health research: the use of the alpha coefficient]. / Estimadores de consistencia interna en las investigaciones en salud: el uso del coeficiente alfa.

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.

Estimadores de consistencia interna en las investigaciones en salud: el uso del coeficiente alfa / Estimators of internal consistency in health research: the use of the alpha coefficient

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.

Health-related quality of life and related factors of military police officers.

PURPOSE: The present study aimed to determine the effect of demographic characteristics, occupation, anthropometric indices, and leisure-time physical activity levels on coronary risk and health-related quality of life among military police officers from the State of Santa Catarina, Brazil. METHODS: The sample included 165 military police officers who fulfilled the study's inclusion criteria. The International Physical Activity Questionnaire and the Short Form Health Survey were used, in addition to a spreadsheet of socio-demographic, occupational and anthropometric data. Statistical analyses were performed using descriptive analysis followed by Spearman Correlation and multiple linear regression analysis using the backward method. RESULTS: The waist-to-height ratio was identified as a risk factor low health-related quality of life. In addition, the conicity index, fat percentage, years of service in the military police, minutes of work per day and leisure-time physical activity levels were identified as risk factors for coronary disease among police officers. CONCLUSIONS: These findings suggest that the Military Police Department should adopt an institutional policy that allows police officers to practice regular physical activity in order to maintain and improve their physical fitness, health, job performance, and quality of life.
