Promoção da saúde e actividade física: contributos para o desenvolvimento humano

A inactividade física é um dos principais factores de risco associados ao desenvolvimento de diferentes patologias, sendo considerada uma questão fundamental de saúde pública nos países ocidentais. Diversas medidas têm sido adoptadas no sentido de favorecer a prática regular de actividade física, de acordo com as directrizes de organismos internacionais, verificando-se um aumento significativo do nível de informação e da oferta existente de programas exercício e saúde. No entanto, não se observam melhorias significativas nos níveis de actividade física, existindo dificuldades na alteração dos comportamentos conducentes a um estilo de vida mais activo. Uma das razões associadas está relacionada com a diferença existente entre os objectivos propostos pelas actividades físicas e as expectativas e motivações dos indivíduos envolvidos nestes programas. O conjunto de características individuais, resultantes também da forma como o indivíduo interage com o mundo exterior, devem ser atendidas neste tipo de actividade. A presente comunicação pretende assim evidenciar as implicações positivas que o conceito Qualidade de Vida (WHO) pode ter na concepção e estruturação das actividades físicas de modo a não serem apenas direccionadas para o desenvolvimento da aptidão física ou para a melhoria de sintomas clínicos, mas que possam contemplar outras necessidades do indivíduo, por vezes negligenciadas

Sexual Function in Women with Breast Cancer : An Evidence Map of Observational Studies

Breast cancer (BC) is the leading cause of cancer in women, and has implications for sexual function (SF). In this study, we used an evidence map to identify, describe, and organise the current available evidence regarding SF in women with BC. We searched the MEDLINE, PsycINFO, and CINAHL databases for observational studies assessing SF in women with BC published in English, Spanish, Portuguese, and French between 2000 and 2021 (sample ≥ 50 women). Of the 64 included studies (13,257 women with BC), 58 were published since 2010. Women who were married, partnered, or in relationships represented 74.1% of the entire sample. Only a single study was conducted on women representing a sexual minority. We identified 22 assessment instruments and 40 sexual dysfunction (SdF) domains. The number of publications on SF in women with BC has increased in the last 10 years, but still remains low. Some groups of women are underrepresented, and some SdF domains are underdiagnosed, with the assessment instrument used affecting which domains are studied. Women with BC need to be better screened, as their quality of life (QoL) is affected by Sd

Educomunicación y Empoderamiento en la Salud Cardiovascular de Residentes de Lisboa

Online educommunication and empowerment are crucial dimensions in awareness, literacy and change processes, and their articulation may bring benefits to cardiovascular health, given that cardiovascular diseases are the deadliest in the world, including in Portugal. This paper aims to explore the relationship between online educommunication and empowerment in cardiovascular health, using Lisbon citizens as a case. The theoretical framework is composed by the interactivity and empowerment model, the health belief model and the uses and gratifications theory. The questionnaire survey was applied to a gender and age quota sample (N=400). The questionnaire includes thematic dimensions, such as online informative practices on cardiovascular health, the eHEALS scale, and the importance and effectiveness of the educommunicative message on cardiovascular health features. Results show that the educommunicative message has characteristics at the level of purpose, content, type, format, emotions, and logic, which enhance it the most. This indicates that exposure to messages with these characteristics may instigate empowerment and behavior change. Respondents self-rated with the most positive levels on the eHEALS scale, showing empowerment at the eHealth level, with age rather than gender differences. There is evidence that eHealth skills and having cardiovascular disease influence information seeking and empowerment. The main contribution lies in identifying characteristics of the cardiovascular health educommunication message that can optimize recipient’s empowerment.La educomunicación en línea y el empoderamiento son dimensiones cruciales en los procesos de concienciación, alfabetización y cambio, y su articulación puede aportar beneficios a la salud cardiovascular, dado que las enfermedades cardiovasculares son las más mortíferas del mundo, incluso en Portugal. Este trabajo pretende explorar la relación entre educomunicación online y empoderamiento en salud cardiovascular, utilizando como caso los residentes del municipio de Lisboa. El marco teórico está compuesto por el modelo de interactividad y empoderamiento, el modelo de creencias en salud y la teoría de usos y gratificaciones. El cuestionario se aplica a una muestra por cuotas de sexo y edad (N=400). El cuestionario incluye dimensiones temáticas, como las prácticas informativas en línea sobre salud cardiovascular, la escala eHEALS, la importancia y la eficacia de las características del mensaje educomunicativo sobre salud cardiovascular. Los resultados muestran que el mensaje educomunicativo tiene características a nivel de propósito, contenido, tipo, formato, emociones y lógica, que lo realzan más, según la evaluación de los encuestados. Esto indica que la exposición a mensajes con estas características puede instigar la capacitación y el cambio de comportamiento. Los encuestados se autocalificaron con los niveles más positivos en la escala eHEALS, lo que demuestra su capacitación a nivel de eSalud, con diferencias más de edad que género. Existen pruebas de que las competencias en eSalud y el hecho de padecer una enfermedad cardiovascular influyen en la búsqueda de información y en la capacitación.info:eu-repo/semantics/publishedVersio

Is there any effect of symmetry on velocity of the four swimming strokes?

The different characteristics of the four swimming strokes affect the interplay between the four limbs, acting as a constraint to the force produced by each hand and foot. The purpose of this study was to analyze the symmetry of force production with a varying number of limbs in action and see its effect on velocity. Fifteen male swimmers performed four all-out bouts of 25-m swims in the four strokes in full-body stroke and segmental actions. A differential pressure system was used to measure the hands/feet propulsive force and a mechanical velocity meter was used to measure swimming velocity. Symmetry index was calculated based on the force values. All strokes and conditions presented contralateral limb asymmetries (ranging from 6.73% to 28% for the peak force and from 9.3% to 35.7% for the mean force). Backstroke was the most asymmetric stroke, followed-up by butterfly, front crawl, and breaststroke. Kicking conditions elicited the higher asymmetries compared with arm-pull conditions. No significant associations were found between asymmetries and velocity. The absence of such association suggests that, to a certain and unknown extent, swimming may benefit from contralateral limb asymmetryFunding: This research was funded by FCT—Portuguese Foundation for Science and Technology through the project UID04045/2020 and the grant SFRH/142009/2018info:eu-repo/semantics/publishedVersio

Doença Pulmonar Obstrutiva Crónica em Portugal: estudo Pneumobil (1995) e estudo de prevalência de 2002 revisitados

ResumoIntroduçãoA doença pulmonar obstrutiva crónica (DPOC) tem sido, ao longo dos anos, uma importante causa de morbilidade e mortalidade no mundo. Em 1995, a implementação de um rastreio da função respiratória pareceu a forma mais adequada para alertar para os sintomas respiratórios negligenciados e sensibilizar para os rastreios espirométricos. Em 2002, foram criadas novas normas consensuais de diagnóstico e o reconhecimento de que a prevalência da DPOC depende dos critérios de definição de obstrução das vias aéreas. O objetivo deste estudo foi revisitar estes 2 estudos e publicar alguns dos resultados e respetivas metodologias.MétodosDos 12 684 indivíduos que constavam da base de dados do Pneumobil, apenas os indivíduos com 40 e mais anos (n = 9061) foram considerados para esta análise. No estudo de 2002 foi incluída uma amostra aleatorizada e representativa de 1384 indivíduos, com idades entre os 35 e os 69 anos.ResultadosA prevalência da DPOC foi de 8,96% no estudo Pneumobil e de 5,34% no estudo de 2002. Em ambos os estudos, a presença da DPOC foi superior no sexo masculino, tendo-se verificado uma associação positiva entre a presença da DPOC e os grupos etários mais velhos. Nos fumadores e ex-fumadores encontrou-se maior proporção de casos com DPOC.ConclusõesA prevalência em Portugal é mais baixa do que noutros países europeus, o que pode estar relacionado com uma menor prevalência de tabagismo. De um modo geral, os fatores de risco mais importantes que mostraram a associação com a DPOC foram a idade maior do que 60 anos, o sexo masculino e a exposição tabágica. Todos os aspetos e as limitações que se referem a diferentes critérios de definição e a metodologias de recrutamento realçam a necessidade de métodos padronizados para determinar a prevalência da DPOC e os fatores de risco associados, cujos resultados possam ser comparados entre países, como acontece no projeto BOLD.AbstractBackgroundChronic Obstructive Pulmonary Disease (COPD) has been a leading cause of morbidity and mortality worldwide, over the years. In 1995, the implementation of a respiratory function survey seemed to be an adequate way to draw attention to neglected respiratory symptoms and increase the awareness of spirometry surveys. By 2002 there were new consensual guidelines in place and the awareness that prevalence of COPD depended on the criteria used for airway obstruction definition. The purpose of this study is to revisit the two studies and to turn public some of the data and respective methodologies.MethodsFrom Pneumobil study database of 12,684 subjects, only the individuals with 40+ years old (n = 9.061) were selected. The 2002 study included a randomized representative sample of 1,384 individuals with 35-69 years old.ResultsThe prevalence of COPD was 8.96% in Pneumobil and 5.34% in the 2002 study. In both studies, presence of COPD was greater in males and there was a positive association between presence of COPD and older age groups. Smokers and ex-smokers showed a higher proportion of cases of COPD.ConclusionsPrevalence in Portugal is lower than in other European countries. This may be related to lower smokers’ prevalence. Globally, the most important risk factors associated with COPD were age over 60 years, male gender and smoking exposure. All aspects and limitations regarding different recruitment methodologies and different criteria for defining COPD cases highlight the need of a standardized method to evaluate COPD prevalence and associated risks factors, whose results can be compared across countries, as it is the case of BOLD project

Nonlinear Analysis of the Hand and Foot Force-Time Profiles in the Four Competitive Swimming Strokes

Human locomotion on water depends on the force produced by the swimmer to propel the body forward. Performance of highly complex motor tasks like swimming can yield minor variations that only nonlinear analysis can be sensitive enough to detect. The purpose of the present study was to examine the nonlinear properties of the hand/feet forces and describe their variations across the four competitive swimming strokes performing segmental and full-body swimming. Swimmers performed all-out bouts of 25 m in the four swimming strokes, swimming the full-body stroke, with the arm-pull only and with the leg kicking only. Hand/foot force and swimming velocity were measured. The Higuchi's fractal dimension (HFD) and sample entropy (SampEn) were used for the nonlinear analysis of force and velocity. Both the arm-pull and leg kicking alone were found to produce similar peak and mean hand/foot forces as swimming the full-body stroke. Hand force was more complex in breaststroke and butterfly stroke; conversely, kicking conditions were more complex in front crawl and backstroke. Moreover, the arm-pull and kicking alone tended to be more complex (higher HFD) but more predictable (lower SampEn) than while swimming the full-body stroke. There was no loss of force production from segmental swimming to the full-body counterpart. In conclusion, the number of segments in action influences the nonlinear behavior of the force produced and, when combining the four limbs, the complexity of the hand/foot force tends to decrease.This research was supported by FCT—Portuguese Foundation for Science and Technology through the project UID04045/2020info:eu-repo/semantics/publishedVersio

Staphylococcus spp. and Lactobacillus sakei Starters with High Level of Inoculation and an Extended Fermentation Step Improve Safety of Fermented Sausages

Paio do Alentejo (PA) is one of the most popular dry-fermented sausages in Portugal. The aim of the present work was to evaluate the effect of a high concentration of starter cultures with an extended fermentation step on the safety and quality of PA. Physicochemical parameters, microbiological parameters, biogenic amines, colour, texture profile, and sensory attributes were assessed. Five starters were selected based on our previous works. Staphylococcus equorum S2M7, Staphylococcus xylosus CECT7057, Lactobacillus sakei CV3C2, Lactobacillus sakei CECT7056, and a yeast strain (2RB4) were co-inoculated in meat batters at a concentration of 108 cfu/g for bacteria and 106 cfu/g for yeast strain, and 0.25% dextrose was added. Inoculated starters significantly reduced pH, Listeria monocytogenes counts, and total content in biogenic amines. The studied starter cultures did not compromise the sensory characteristics of PA, and thus, their use can be considered to protect these sausages and contribute to their safet
