Health literacy, a more complex concept than knowledge, is a required capacity to obtain, understand, integrate and act on health information [1], in order to enhance individual and community health, which is defined by different levels, according to the autonomy and personal capacitation in decision making [2]. Medium levels of Health literacy in an adolescent population were found in a study conducted in 2013/2014, being higher in sexual and reproductive health and lower in substance use. It was also noticed that the higher levels of health literacy were in the area adolescents refer to have receipt more health information. The health literacy competence with higher scores was communication skills, and the lower scores were in the capacity to analyze factors that influence health. Higher levels were also found in younger teenagers, but in a higher school level, confirming the importance of health education in these age and development stage. Adolescents seek more information in health professionals and parents, being friends more valued as a source information in older adolescents, which enhance the importance of peer education mainly in older adolescents [3]. As a set of competences based on knowledge, health literacy should be developed through education interventions, encompassing the cultural and social context of individuals, since the society, culture and education system where the individual is inserted can define the way the development and enforcement of the health literacy competences [4]. The valued sources of information should be taken into account, as well as needs of information in some topics referred by adolescents in an efficient health education. Schizophrenia is a serious and chronic mental illness which has a profound effect on the health and well-being related with the well-known nature of psychotic symptoms. The exercise has the potential to improve the life of people with schizophrenia improving physical health and alleviating psychiatric symptoms. However, most people with schizophrenia remains sedentary and lack of access to exercise programs are barriers to achieve health benefits. The aim of this study is to evaluate the effect of exercise on I) the type of intervention in mental health, II) in salivary levels of alpha-amylase and cortisol and serum levels of S100B and BDNF, and on III) the quality of life and selfperception of the physical domain of people with schizophrenia. The sample consisted of 31 females in long-term institutions in the Casa de Saúde Rainha Santa Isabel, with age between 25 and 63, and with diagnosis of schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Physical fitness was assessed by the six-minute walk distance test (6MWD). Biological variables were determined by ELISA (Enzyme-Linked Immunosorbent Assay). Psychological variables were assessed using SF-36, PSPP-SCV, RSES and SWLS tests. Walking exercise has a positive impact on physical fitness (6MWD -p = 0.001) and physical components of the psychological test...

ABSTRACT. The Easter Island Province (EIP) encompasses Easter Island (EI) and Salas y Gómez Island (SGI), which are located in the eastern boundary of the south Pacific subtropical gyre. This province is one of the most oligotrophic region in the world ocean with a high degree of endemism and distinguished by having the clearest waters in the world. Issues related to the biophysical coupling that sustains biological production in this region are still poorly understood. Satellite data compiled over a ten year period was used to characterize the spatial and temporal chlorophyll-a (Chl-a) variability around the EIP and determine the relationship between Chl-a and several physical forcing. Results shows a clear Chl-a annual cycle around the EIP, with maximum concentration during the austral winter. Chl-a spatial distribution shows a strong zonal dipole over EI that divides the island into two zones: southeast and northwest. Due to its small size and low elevation of SGI, it does not generate a significant local effect in Chl-a concentration, but a Chl-a increase is observed southeast of this island (~2 km) associated to a seamount. The mean geostrophic current in the EIP flows eastward, associated with the southeastern boundary of the subtropical gyre. However, recurrent mesoscale eddies traveling northwestward and produce large surface current variability with periods of high velocities in opposite direction. In the spring, wakes of high Chl-a concentration can be observed over EI, associated with the generation and detachment of submesoscale eddies from EI, which could have important biological implications during periods of low regional biological production.Keywords: satellite chlorophyll-a, mesoscale and submesoscale eddies, subtropical anticyclonic gyre, Easter Island, Salas y Gómez Island, southeastern Pacific.Variabilidad espacio-temporal de la clorofila-a satelital en la Provincia de Isla de Pascua, Océano Pacífico suroriental RESUMEN. La Provincia de Isla de Pascua (PIP) está compuesta por las islas de Pascua (IP) y Salas y Gómez (ISG). Ambas islas se sitúan en el límite oriental del giro subtropical del Pacífico sur. Esta provincia es una de las regiones más oligotróficas en el océano mundial con un alto grado de endemismo y se distingue por tener las aguas más transparentes del mundo. Los aspectos relacionados con el acoplamiento biofísico que dan sustento a la producción biológica de esta región, son escasamente conocidos. Se utilizaron 10 años de información satelital para caracterizar la variabilidad espacial y temporal de la clorofila-a (Clo-a) alrededor de la PIP, y determinar su relación con los distintos forzantes físicos. Los resultados muestran un marcado ciclo anual de la Clo-a alrededor de la PIP, con mayores concentraciones durante invierno. La distribución espacial de la Clo-a, muestra un marcado dipolo zonal en IP que divide a la isla en una zona sureste y otra noroeste. La ISG, debido a su pequeño tamaño y escasa altura, no genera un efecto local significativo sobre las concentraciones de...

Enquadramento: O Newest Vital Sign (NVS) foi construído para ser um instrumento de administração simples e rápida de avaliação da Literacia em Saúde (LS). Objetivos: Disponibilizar um instrumento em língua portuguesa para a avaliação de LS da população portuguesa. Metodologia: Tradução para a língua portuguesa e adaptação cultural da versão original inglesa do NVS. O processo de validação incluiu a análise fatorial e a avaliação das propriedades psicométricas e o estudo da associação com a autoeficácia, Índice de Massa Corporal (IMC), idade e estilos de vida. Resultados: A fiabilidade foi aceitável, com alfa de Cronbach entre 0,67 e 0,83. Da análise fatorial com rotação ortogonal varimax obteve-se uma solução de dois fatores que explicam 60,97% da variância. A validade de construção foi ainda suportada pela confirmação das correlações entre a versão portuguesa do NVS (NVS-PT) e a idade, IMC e SES (validade convergente-divergente) e pelo facto de os mais velhos pontuarem mais baixo no NVS-PT (p = 0,001). Conclusão: A versão portuguesa do NVS evidenciou características psicométricas aceitáveis. Theoretical framework: The Newest Vital Sign (NVS) test was designed for simple, easy administration on Health literacy (HL) measurement. Objectives: To make available an instrument in Portuguese to assess the HL level of the Portuguese population. Methodology: Translation and cross-cultural adaptation of the original English version of the NVS into the Portuguese language. The validation process included the factor analysis and the establishment of its psychometric proprieties and the study of the association with other individual factors, such as the self-efficacy, Body Mass Index (BMI), age and lifestyles. Results: Reliability was acceptable with Cronbach's alpha coefficient between .67 and .83. Using factor analysis with varimax rotation, two subscales explained 60.97% of the variance. Construct validity was also supported by the confirmation of predefined hypotheses involving expected correlations between the Portuguese version (NVS-PT), BMI, age and SES (convergent-divergent validity). An additional predefined hypothesis was also confirmed with the older subjects obtaining a lower score in the NVS-PT (p = .001). Conclusion: The NVS-PT evidenced acceptable psychometric characteristics.
