Comportamentos aditivos com e sem substância em adolescentes: relação com a idade e o sexo / Additive behaviors with and without substance in adolescents: relation with age and sex

Resumo Contexto: O fenómeno da adição, com e sem substância, constitui um problema na adolescência pelo impacto negativo em diferentes domínios, nomeadamente na saúde mental. Assim, é fundamental que as equipas de saúde escolar conheçam a prevalência e características dos consumos aditivos dos adolescentes. Objetivo(s): Caracterizar o consumo aditivo com substância (tabaco, álcool e drogas) e sem substância (internet, jogos e redes sociais) em adolescentes, e relacionar os consumos entre si e com as variáveis idade e sexo. Métodos: Estudo transversal, descritivo-correlacional, com a aplicação de um questionário de autopreenchimento em contexto escolar, com uma amostra não probabilística constituída por 571 adolescentes. Resultados: O tabaco, o álcool, a internet e as redes sociais foram as adições mais prevalentes nos adolescentes. Foi encontrada associação entre o consumo de álcool e drogas ilícitas e as variáveis idade e sexo; e entre o consumo de álcool e o grupo etário. Existe correlação positiva e significativa entre o consumo de tabaco e o consumo de drogas; e correlação entre o consumo de álcool com os consumos de tabaco e drogas. Conclusões: Os adolescentes com consumo aditivo a uma substância apresentavam também outras adições, com ou sem substância. O presente estudo realça a necessidade de reforçar os programas de educação para a saúde na comunidade educativa com enfoque na prevenção de comportamentos aditivos com e sem substância nos adolescentes.

Abstract Background: The addiction behaviour is problematic due to its negative impact on adolescents' psychosocial well-being, including their mental health. Thus, it is essential that school health teams know the prevalence and the characteristics of adolescent addictive behaviours. Aim: To characterize addictive behaviour with substance (tobacco, alcohol, and drugs) and without substance (internet, games, and social media) in adolescents and to relate the additive behaviours with and without substance and with the variables age and sex. Methods: Cross-sectional, descriptive-correlational study with the application of a self-administered questionnaire, in a school context, to a non-probabilistic sample of 571 adolescents. Results: Tobacco, alcohol, the internet, and social media are the most prevalent adolescents' additions. Alcohol and illicit drugs consumption are associated with the variables age and sex, and alcohol consumption is associated with age. There is a positive and significant correlation between tobacco use and drug; and correlation between alcohol consumption and tobacco and drug consumption. Conclusions: Adolescents with addictive consumption on one substance have also other additions, with or without substance. The present study highlights the need to reinforce health education programs in the educational community with a focus on preventing addictive behaviors with and without substance in adolescents.

Bem-estar Psicológico e Utilização Problemática da Internet em Adolescentes / Psychological Well-Being and Problematic Use of the Internet in Adolescents

Resumo Contexto: A internet mudou os comportamentos dos adolescentes e trouxe novas formas de socialização e comunicação. Para além das suas vantagens, a utilização excessiva pode ter implicações no domínio pessoal, familiar, social e académico, com possíveis consequências nefastas para a saúde e bem-estar psicológico dos mais jovens. Objetivo(s): Caracterizar o bem-estar psicológico e a utilização da internet; relacionar o uso problemático da Internet com o bem-estar psicológico dos adolescentes; e relacionar o bem-estar psicológico dos adolescentes com as variáveis sociodemográficas, escolares e utilização da internet. Métodos: Estudo descritivo-correlacional e transversal com uma amostra de 478 adolescentes, com média de M=14,5 anos (DP=1,9), em contexto escolar. Aplicou-se um questionário que incluía a caracterização sociodemográfica e questões sobre a utilização da internet, o Questionário de Bem-estar Psicológico, versão reduzida (QBEP-R) e a Escala do Uso Generalizado e Problemático da Internet (GPIUS2). O tratamento estatístico foi efetuado com recurso à análise descritiva e inferencial. Resultados: Foram observados níveis satisfatórios e elevados de bem-estar psicológico nos adolescentes e utilização problemática da Internet em 13,4% da amostra. Verificou-se uma correlação negativa entre a utilização problemática da internet e o bem-estar psicológico. Constataram-se diferenças estatisticamente significativas no bem-estar psicológico em relação às variáveis: idade, sexo, nível de ensino, presença de hobby, utilização das redes sociais e jogos online. Conclusões: Os adolescentes com utilização problemática da internet apresentavam menor bem-estar psicológico, o que justifica a intervenção dos profissionais de saúde, na implementação de estratégias que promovam comportamentos saudáveis e consequentemente o bem-estar psicológico.

Abstract Background: The internet has changed the behavior of teenagers and brought new forms of socialization and communication. However, beyond its advantages there are also some risks. Excessive use can have consequences in the personal, family, social and academic domain, with possible harmful effects on the health and psychological well-being of youngsters. Aim: To characterize the psychological well-being and the use of the internet and to relate the problematic use of the Internet to the psychological well-being of adolescents. Methods: Descriptive-correlational, cross-sectional, and quantitative study, with a sample about 478 adolescents, with an average age of M=14,5 years old (SD =1,9), in a school context. A questionnaire was applied that included the sociodemographic characterization and use of the internet, the Psychological Well-being Questionnaire, short version (QBEP-R) and the Scale of Generalized and Problematic Use of the Internet (GPIUS2). The statistical treatment was performed using descriptive and inferential analysis. Results: Satisfactory and high levels of psychological well-being were observed in adolescents, and problematic use of the Internet was held by 13,4% of the sample. There was a negative correlation between problematic use of the Internet and psychological well-being. There were statistically significant differences in psychological well-being in relation to the variables: age, sex, level of education, presence of hobby, use of social networks and online games. Conclusions: Adolescents with problematic use of the internet have lower psychological well-being, which justifies the intervention of health professionals, namely nurses, in the implementation of strategies that promote healthy online behaviours and, consequently, psychological well-being.

Differential Impact of the Pinewood Nematode on Pinus Species Under Drought Conditions.

The pinewood nematode (PWN), Bursaphelenchus xylophilus, responsible for the pine wilt disease (PWD), is a major threat to pine forests worldwide. Since forest mortality due to PWN might be exacerbated by climate, the concerns regarding PWD in the Mediterranean region are further emphasized by the projected scenarios of more drought events and higher temperatures. In this context, it is essential to better understand the pine species vulnerability to PWN under these conditions. To achieve that, physiological responses and wilting symptoms were monitored in artificially inoculated Pinus pinaster (P. pinaster), Pinus pinea (P. pinea), and Pinus radiata (P. radiata) saplings under controlled temperature (25/30°C) and water availability (watered/water stressed). The results obtained showed that the impact of PWN is species-dependent, being infected P. pinaster and P. radiata more prone to physiological and morphological damage than P. pinea. For the more susceptible species (P. pinaster and P. radiata), the presence of the nematode was the main driver of photosynthetic responses, regardless of their temperature or water regime conditions. Nevertheless, water potential was revealed to be highly affected by the synergy of PWN and the studied abiotic conditions, with higher temperatures (P. pinaster) or water limitation (P. radiata) increasing the impact of nematodes on trees' water status. Furthermore, water limitation had an influence on nematodes density and its allocation on trees' structures, with P. pinaster revealing the highest nematode abundance and inner dispersion. In inoculated P. pinea individuals, nematodes' population decreased significantly, emphasizing this species resistance to PWN. Our findings revealed a synergistic impact of PWN infection and stressful environmental conditions, particularly on the water status of P. pinaster and P. radiata, triggering disease symptoms and mortality of these species. Our results suggest that predicted drought conditions might facilitate proliferation and exacerbate the impact of PWN on these two species, through xylem cavitation, leading to strong changes in pine forests of the Mediterranean regions.

Acorn Isotopic Composition: A New Promising Tool for Authenticity Maps of Montado's High-Value Food Products.

It is often overlooked that even food production is linked to the ecology of plants and animals. Living organisms respond to environmental short-and long-term variability: acknowledging this may help in the ultimate goal of valorizing a territory/product. We investigated acorns of the two main Quercus species of the Portuguese Montado, a main feed of the renown black Iberian pig. We tested their responses to an aridity gradient by morphological parameters and isotopic signature. Q. rotundifolia and Q. suber acorns did not differ morphologically, even if a higher variability in all parameters was observed in acorns of Q. suber. According to the site-specific Aridity Index, correlations are indicative to higher weight and length only in Q. suber acorns from more arid sites. As for isotopic composition, there were no differences in nitrogen or carbon (δ15N and δ13C) between the two species. However, combining the samples and testing for association with the Aridity Index, we found that more arid sites lead to a 15N enrichment. This result, combined with the positive correlation between AI and acorns length, support the use of acorns as a tool, their isoscapes of nitrogen being a stepping stone for the provenance of the black Iberian pig.

Functional capacity and self-care profiles of older people in senior care homes.

The reduction of the functional capacity in older people is the result of physical, psychological and functional changes related to the ageing process, compromising the performance of daily life activities. Assessing their functional capacity and their self-care profile can facilitate the planning of targeted strategies related to stimulation, as well as cognitive and motor rehabilitation. This study aims to evaluate and analyse the functional capacity, as well as the level of dependence in self-care of older people in senior care centres. This is a transversal exploratory study, quantitative in nature. The sample was comprised of 313 participants, randomly selected from a set of senior care centres, with an average age of 83.41 (SD=7.14) years, recruited from the interior North of Portugal. The data collection instruments included the Barthel Index, the Lawton and Brody Scale, the Evaluation Form of Dependence in Self-care, the Self-care of Home Dwelling Elderly (self-care subscale profiles) and a questionnaire on demographic data. The elderly showed several levels of dependence on different self-care items. It was possible to observe that the staff often replaces the elderly in many of the tasks that could still be performed by them, and thus aggravates their levels of dependence. The link observed between functional capacity and self-care profiles highlights the need to focus on the notion of a healthy and active ageing process, especially in some profiles. The monitoring of the functional capacity and the self-care profile can provide knowledge concerning the potential for autonomy and individual needs, thus enabling targeted and more responsive interventions for the individual and the real needs of older people.

The link between cognitive state and general self-esteem among institutionalized elderly persons: can health condition serve as a mediating factor? / Associação entre estado cognitivo e autoestima global em idosos institucionalizados: será a condição de saúde um mediador?

Abstract Objective: to assess whether the health condition of an elderly person can serve as a mediating factor between the cognitive state and general self-esteem of the institutionalized elderly. Method: a quantitative, cross-sectional correlational study was performed, based on the path analysis technique.The following instruments were used for data collection: the Mini-Mental State Examination, the Tinetti Performance Oriented Mobility Assessment, the Mini Nutritional Evaluation and the Rosenberg Self-Esteem Scale. Results: the sample was composed of 312 elderly patients of both genders (112 men and 200 women), with an average age of 83.39 (+7.09) years. Most of the elderly persons were widowed, with a low educational level, and had been institutionalized in Residential Care Facilities for the Elderly for on average 54.6 (+51.69) months. The mediating factor of health condition renders the link between the cognitive state and self-esteem of the elderly null. However, the analysis of the decomposition of the effects showed a significant indirect effect between the cognitive state and health condition. The total effect of cognitive state on the health condition of the elderly is significant, positive and direct. Conclusion: based on the results of this study we maintain that cognitive changes can affect the nutritional state and physical balance of the institutionalized elderly. AU

Resumo Objetivo: testar se a condição de saúde da pessoa idosa é mediadora na associação entre o estado cognitivo e a autoestima global de idosos institucionalizados. Método: estudo de natureza quantitativa, transversal do tipo correlacional, recorreu à análise de caminhos. Na recolha de dados utilizaram-se as versões portuguesas dos seguintes instrumentos: Mini-Mental State Examination, Tinetti Performance Oriented Mobility Assessement, Miniavaliação Nutricional e a Rosenberg Self-Esteem Scale. Resultados: a amostra foi constituída por 312 idosos de ambos os gêneros (112 homens e 200 mulheres), com média etária de 83,39 (±7,09) anos. A maioria dos idosos eram viúvos, com baixa escolaridade, institucionalizados em Equipamentos Residenciais para Pessoas Idosas em média há 54,60 (±51,69) meses. Não se confirmou a mediação da condição de saúde na associação entre estado cognitivo e autoestima nos idosos. Contudo, a análise da decomposição dos efeitos indicou a existência de um efeito significativo indireto do estado cognitivo na autoestima e na condição de saúde. O efeito total do estado cognitivo na condição de saúde dos idosos é significativo, positivo e direto. Conclusão: os resultados desse estudo permitem-nos afirmar que as alterações cognitivas podem afetar o estado nutricional e o equilíbrio corporal dos idosos institucionalizados. AU

Groundwater drawdown drives ecophysiological adjustments of woody vegetation in a semi-arid coastal ecosystem.

Predicted droughts and anthropogenic water use will increase groundwater lowering rates and intensify groundwater limitation, particularly for Mediterranean semi-arid ecosystems. These hydrological changes may be expected to elicit differential functional responses of vegetation either belowground or aboveground. Yet, our ability to predict the impacts of groundwater changes on these ecosystems is still poor. Thus, we sought to better understand the impact of falling water table on the physiology of woody vegetation. We specifically ask (a) how is woody vegetation ecophysiological performance affected by water table depth during the dry season? and (b) does the vegetation response to increasing depth to groundwater differ among water-use functional types? We examined a suite of physiological parameters and water-uptake depths of the dominant, functionally distinct woody vegetation along a water-table depth gradient in a Mediterranean semi-arid coastal ecosystem that is currently experiencing anthropogenic groundwater extraction pressure. We found that groundwater drawdown did negatively affect the ecophysiological performance of the woody vegetation. Across all studied environmental factors, depth to groundwater was the most important driver of ecophysiological adjustments. Plant functional types, independent of groundwater dependence, showed consistent declines in water content and generally reduced C and N acquisition with increasing depths to groundwater. Functional types showed distinct operating physiological ranges, but common physiological sensitivity to greater water table depth. Thus, although differences in water-source use exist, a physiological convergence appeared to happen among different functional types. These results strongly suggest that hydrological drought has an important impact on fundamental physiological processes, constraining the performance of woody vegetation under semi-arid conditions. By disentangling the functional responses and vulnerability of woody vegetation to groundwater limitation, our study establishes the basis for predicting the physiological responses of woody vegetation in semi-arid coastal ecosystems to groundwater drawdown.

Self-care profiles of the elderly institutionalized in Elderly Care Centres.

The concept of self-care in the elderly has been frequently associated with autonomy, independence and personal accountability. Self-care practices are a result of individual lifestyles and paths adapted to the circumstances and expectations of the elderly. Based on the model by Backman and Hentinen (1999), the present study attempts to categorically describe the types of self-care of the elderly. This is an exploratory study, transversal, of a quantitative nature. The sample was comprised of 313 participants, randomly selected among Elderly Care Centres in the interior North of Portugal. The Portuguese version of Self-care of Home Dwelling Elderly was used for data collection. The results call for a replication of the study, using the theoretical derivation of the four self-care profiles (responsible, formally guided, independent and abandoned).

Objetivo: Conocer el perfil funcional de los ancianos que viven en instituciones geriátricas, en una ciudad de Trás-os-Montes. Metodología: Este es un estudio de carácter exploratorio que utilizó la estadística descriptiva con el fin de definir los perfiles de las personas mayores en estudio. La investigación contó con una muestra de 82 sujetos. Instrumentos: Mini-Mental State Examination; Formulario de Evaluación de la Dependencia de Autocuidado; Índice de Barthel; Escala de Lawton y Brody, y un Formulario de evaluación del estado de salud. Resultados: Los ancianos que viven en residencias son, en su mayoría, mujeres, con una edad media de 81,8 años y viudos, con bajo nivel de escolarización y que presentan un promedio de estancia en la institución de 21,5 meses. En cuanto al estado cognitivo, el 68,3% (56) manifiesta algún déficit cognitivo. Dependen de todos los autocuidados el 12,7% de la muestra, y el 22,27% necesita ayuda de personas o aparatos. Casi todos (95,1%) requieren asistencia para preparar y tomar los medicamentos prescritos, teniendo en cuenta que el 69,6% de las personas mayores presentan cambios en el estado nutricional y el 79,3%, problemas articulatorios de los miembros. También el 62,2% tiene problemas de eliminación, incluyendo la incontinencia urinaria, y el 30,5%, problemas de estreñimiento. Conclusiones: Los ancianos residentes en instituciones geriátricas presentan problemas que requieren la atención básica de la salud, por lo que se considera de extrema importancia la necesidad de desarrollar modelos de intervención en enfermería que promuevan el autocuidado, la independencia y la autonomía

Context: The loss of autonomy and independence among the elderly contribute to an increase in the rate of institutional care. Objectives: To develop a functional profile of the elderly residing in residential care facilities in the surrounding region of a town in the Trás-os-Montes region. Methodology: This is an exploratory study using descriptive statistics to establish the profile of the elderly involved in the study. The research was based on a convenience sample of 82 subjects. Instruments: Mini-Mental State Examination; Self-Care Evaluation Form; Barthel Index; Lawton and Brody Scale and a Health Evaluation Form. Results: The elderly who are in residential care are primarily widowed women, with an average age of 81.8, and with a low level of education, who reside in these institutions for an average of 21.5 months. In terms of their cognition, 68.3% (56) show a cognitive deficit, while 12.7% are dependent on all aspects of self-care, and 22.27% need assistance from someone or from some type of equipment. Nearly all the subjects, 95.1%, require assistance to prepare and to take medication prescribed to them. It is important to note that 69.6% of the elderly show changes in their nutritional state and that 79.3% have a limited range of motion. In addition, 62.2% have elimination problems, especially urinary incontinence, while 30.5% have constipation problems. Conclusions: The institutionalized elderly experience problems related to basic health care, highlighting the need to create intervention plans to promote self-care, independence and autonomy

Evaluating green infrastructure in urban environments using a multi-taxa and functional diversity approach.

Forested areas within cities host a large number of species, responsible for many ecosystem services in urban areas. The biodiversity in these areas is influenced by human disturbances such as atmospheric pollution and urban heat island effect. To ameliorate the effects of these factors, an increase in urban green areas is often considered sufficient. However, this approach assumes that all types of green cover have the same importance for species. Our aim was to show that not all forested green areas are equal in importance for species, but that based on a multi-taxa and functional diversity approach it is possible to value green infrastructure in urban environments. After evaluating the diversity of lichens, butterflies and other-arthropods, birds and mammals in 31 Mediterranean urban forests in south-west Europe (Almada, Portugal), bird and lichen functional groups responsive to urbanization were found. A community shift (tolerant species replacing sensitive ones) along the urbanization gradient was found, and this must be considered when using these groups as indicators of the effect of urbanization. Bird and lichen functional groups were then analyzed together with the characteristics of the forests and their surroundings. Our results showed that, contrary to previous assumptions, vegetation density and more importantly the amount of urban areas around the forest (matrix), are more important for biodiversity than forest quantity alone. This indicated that not all types of forested green areas have the same importance for biodiversity. An index of forest functional diversity was then calculated for all sampled forests of the area. This could help decision-makers to improve the management of urban green infrastructures with the goal of increasing functionality and ultimately ecosystem services in urban areas.

Percepção de apoio social na adolescência: análise fatorial confirmatória da escala Social Support Appraisals / Social Support Appraisals during adolescence: a confirmatory factor analysis of the Social Support Appraisals scale

Durante a adolescência, a percepção de apoio social parece estar relacionada com o ajustamento psicossocial do adolescente e com o processo de desenvolvimento da sua auto-estima e da sua identidade. Este estudo aprecia algumas das qualidades psicométricas de ums instrumento construído por Vaux para avaliar a percepção dos adolescentes do apoio emocional recebido da família, dos amigos e dos professores, o Social Support Appraisal (SSA). A sua consistência interna em estudantes portugueses do 7º ao 12º ano de escolaridade é satisfatória e melhora com a progressão na escolaridade. A sua estrutura, evidenciada graças ao recurso à técnica de modelação de estruturas covariantes (análise fatorial confirmatória, com o programa EQS, Bentler) revelou-se multidimensional e hierárquica, formada por um fator de segunda ordem e por três fatores de primeira ordem, que diferenciam a percepção de apoio social dos amigos, dos professores e da família.(AU)
