Significações de envelhecimento, variáveis relacionais subjectivas e bem-estar psicológico em idosos

O presente estudo pretendia avaliar se as perceções de envelhecimento teriam influência no bem-estar psicológico dos idosos. Procurou-se compreender qual o efeito da influência (moderação ou mediação), das variáveis relacionais subjetivas: apoio social, religiosidade, perceção de saúde e estado emocional. O estudo foi realizado numa amostra portuguesa de 150 idosos, com idades compreendidas entre os 65 e os 99 anos. Foram utilizados dez instrumentos de avaliação. Os resultados mostram, que as perceções de envelhecimento, conjuntamente com a avaliação que as pessoas fazem do seu estado de saúde e dos sintomas psicopatológicos, predizem de forma significativa, a perceção do seu bem-estar psicológico. O apoio social e a religiosidade, são variáveis mediadoras, enquanto, a ansiedade existencial e o estado emocional, são moderadoras. Podemos verificar que existem diferenças significativas entre as diversas variáveis sócio-demográficas. Com o aumento da esperança de vida, pretende-se que este estudo contribua para a compreensão das dimensões pessoais intra e interindividuais do envelhecimento. ABSTRACT: The present study it intended to assess whether the perceptions of aging will impact on psychological well-being of the elderly. We tried to understand, what effect the influence (moderation or mediation), the relational subjective variables: social support, religiosity, health perception and emotional state. The study was conducted in a Portuguese sample of 150 elderly people, aged between 65 and 99 years. Ten instruments were used for evaluation. The results show that perceptions of aging, jointly with the assessment that people make in their state of health and psychopathology predict significantly the perception of their psychological well-being. Social support and religiosity, are mediating variables, while the existential anxiety and emotional state, they are moderating. We can see that there are significant differences between the various socio-demographic variables. With the increase of the life hope, it is intended that this study contributes to the understanding of intra and inter-personal dimensions of aging.

Oral food perception and polyphenol-rich foods acceptance - the importance of knowing individuals saliva characteristics for promoting consumption

Polyphenols are widely present in fruits, vegetables, cereals and beverages. Their study gained scientific interest because of their beneficial effects on health. Although there is currently no official dietary recommendation for polyphenol intake, health professionals recommend the consumption of 5-8 daily portions of fruits and vegetables. This is not always achieved and, despite possible causes associated to practical schedule difficulties, the aversive bitter and astringent sensations associated to polyphenols may also lead to avoidance. As such, a better understanding on mechanisms responsible for differences among people, in polyphenol oral perception, is needed for promoting healthier choices. Saliva has been linked to polyphenol consumption. We have previously observed, in animal models, changes in salivary proteome induced by tannin-enriched diets. Moreover, differences in astringency perception were attributed to differences in salivary protein composition. In a recent experiment, we observed differences among individuals with dissimilar tannic-acid perception: people with high sensitivity for the oral sensations elicited by tannins have higher amounts of salivary cystatins and lower capacity to maintain their levels after tannic-acid ingestion. Additionally, and similarly to previous studies, salivary amylase was observed to be involved in tannin perception. In this presentation, oral cavity characteristics influencing the perception of polyphenol-containing foods will be discussed.

the health and well-being of nursing students in clinical practice . what prevents it? what promotes it?

Introduction: The training of nursing students in the context of clinical practice, is characterized by educational experiences, subject to various emotional stress (stress, ambivalence, frustration, conflict), sometimes making it very vulnerable student.However not all students use the same strategies minimizing their meanings and negative effects on the level of your health and well-being Objetiv:To analyze the perception that nursing students have about the determinants of their health status and well-being in clinical practice Methods: Exploratory research Results:The results reveal the complexity of the teaching / learning process in clinical practice, identified determinants that limit and / or promote health and well-being of students, or not contributing to their motivation, self-confidence and learning. All students value the presence of the following dimensions: affective-emotional (humanization in learning experiences); relational dynamics (interactions developed with all stakeholders); methods used (professional competence of the clinical supervisor and teacher); school curriculum (adaptation of learning in theory); socialization to the profession (become nurse).Conclusions: The results indicate, that although all students evidencing the dimensions described as fundamental to learning in clinical practice, the study results are dichotomous and ambivalent. Students 2nd and 3ºanos refer a low perception in clinical practice, the indicated dimensions, and for these source of concern and uncertainty in learning, such as limiting their health condition and well-being. For students of the 4th year, these dimensions are percecionadas as gifts, and sources of motivation, learning and catalysts such as promoting their health and well-being.
