- Solidão em idosos do meio rural do concelho de BragançaPublication . Fernandes, HélderApós o enquadramento teórico onde se exploram os conceitos sobre o envelhecimento e a solidão, e também sobre a situação de saúde, inicia-se a parte prática no sentido de procurar encontrar os níveis de solidão subjectiva que os idosos reconhecem neles próprios. Objectivo: Trata-se de um estudo exploratório e descritivo, utilizando dois instrumentos de medida, um deles, a escala SELSA, concebida por DiTommaso, Brannen e Best (2004); e outro, a escala UCLA, traduzida e validada para a população Portuguesa por Neto (1989). Metodologia: A amostra inclui 179 idosos, 56 da aldeia de Rio de Onor e 123 da aldeia de Parada, com idades compreendidas entre os 60 e os 92 anos. A variabilidade dos itens e as componentes de solidão associadas à diferença entre as características da amostra foi testada através do teste ANOVA e X2. Na análise factorial realizada para os itens da escala SELSA, (DiTommaso, Brannen e Best, 2004) foi aceite o nível de saturação de valores iguais ou superiores a 0.4 e a consistência interna dos itens de cada componente foi testada através do alpha de Cronbach, tendo sido aceite a consistência interna a partir de valores iguais ou superiores a 0.7. Posteriormente foram feitas análises de variância (ANOVA) dos níveis de solidão por variáveis de caracterização. Resultados: Foi encontrado que as variáveis sociodemográficas, de saúde e antropométricas influenciam o nível de percepção subjectiva de solidão. Conclusão: Foi confirmada a Hipótese central do estudo: existe uma correlação positiva entre a maioria dos itens da escala SELSA de DiTommaso, Brannen e Best (2004) e os valores relativos à percepção subjectiva de solidão sentida pelos idosos. Foi confirmado que existem diferenças estatisticamente significativas entre os níveis de percepção subjectiva de solidão sentida por idosos na dimensão social. Verificaram-se relações entre a percepção subjectiva de solidão, as variáveis de caracterização sócio-demográfica e as variáveis de caracterização do estado de saúde. After the theoretical framing where if they explore the concepts on the aging and the loneliness, and also on the health situation, initiates it part practical in the direction to look for to find the levels of subjective loneliness that the aged ones recognize in proper them. Objective: Is a exploratory and descriptive study, using two instruments of measure, one of them, scale SELSA, conceived for DiTommaso, Brannen and Best (2004); and another one, the scale UCLA, translated and validated for the Portuguese population for Neto (1989). Methodology: The sample includes 179 aged ones, 56 of the village of Rio de Onor and 123 of the village of Parada, with ages understood between the 60 and 92 years. The variability of the item and the components of loneliness associates to the difference enter the characteristics of the sample were tested through test ANOVA and X2. In the carried through factorial analysis for the items’ of scale SELSA, (DiTommaso, Brannen and Best, 2004) has accepted the level of saturation of equal values or superior the 0,4 and internal consistency of the items’ of each component was tested through alpha of Cronbach, having been it has accepted the internal consistency from equal or superior values the 0.7. Later analyses of variance (ANOVA) of the levels of loneliness for characterization variable had been made. Results: It was found that the sociodemographics variables, health and anthropometrics, influence the level of subjective perception of loneliness. Conclusion: The central hypothesis of the study was confirmed: a positive correlation exists enters the relative majority of the item of scale SELSA of DiTommaso, Brannen e Best (2004) and values to the subjective perception of loneliness felt for the aged ones. It was confirmed that significant differences between the levels of subjective perception of loneliness felt for aged exist statistical in the social dimension. Relations between the subjective perception of loneliness, the variable of sociodemographic characterization and the variable of characterization of the health state had been verified.
- Sleep quality and hormonal levels of ghrelin and leptin in the elderly: a cross-sectional studyPublication . Alves, Sara; Capristano, Jeovana; Sá, Leandro Moreira de; Mendes, Eugénia; Fernandes, Hélder; Vaz, Josiana A.The increase in life expectancy prompts a critical examination of the quality of aging in contemporary societies. Ageing causes alterations in the circadian sleep-wake cycle, which are closely linked to cellular senescence. Research indicates that insufficient sleep can accelerate inflammation and oxidative stress, highlighting the importance of good sleep hygiene for overall health and reducing the effects of ageing. Sleep quality is closely connected to hormonal balance, particularly ghrelin, leptin, melatonin, and serotonin. These hormones play significant roles in regulating appetite, metabolism, sleep patterns, and emotional well-being. This study aimed to evaluate sleep quality in a group of elderly individuals (N=25) and its relationship with serum levels of ghrelin and leptin. Sleep quality was assessed using the Portuguese version of the Pittsburgh Sleep Quality Index. Blood collection for laboratory tests was performed according to WHO guidelines
- Exploring cardiovascular risk and plasma ghrelin levels in older adults: a preliminary studyPublication . Alves, Sara; Capristano, Jeovana; Sá, Leandro Moreira de; Mendes, Eugénia; Fernandes, Hélder; Vaz, Josiana A.Cardiovascular diseases are a leading cause of illness and mortality worldwide, with ageing as a key risk factor. As people age, heightened inflammation, oxidative stress, and endothelial dysfunction increase their cardiovascular disease risk. Ghrelin, known as "the hunger hormone," is essential for energy regulation and metabolism. It offers cardiovascular benefits by promoting vasodilation and enhancing endothelial function. With anti-inflammatory and antioxidative properties, ghrelin aids vascular health, making it particularly significant for ageing populations where these processes are often disrupted. Imbalanced ghrelin levels may increase the risk of atherosclerosis and other cardiovascular complications. Understanding these variations in plasma ghrelin levels can offer insights into individual susceptibility to cardiovascular disease and highlight the hormone's role in metabolic and cardiovascular health. This preliminary study aimed to evaluate cardiovascular risk and plasma ghrelin levels in a community of 16 older adults aged 60 or above
