Resistance training for the older adult: Manipulating training variables to enhance muscle strength

Resistance training has been shown to reliably and substantially enhance muscle function in older adults and these improvements can be accompanied by improved functional performance. Training variables should be manipulated to enhance muscle strength and minimize injury risks in this population.

QUALIDADE DE VIDA, PERCEPÇÃO DE SUPORTE SOCIAL E CONSUMO DE MEDICAMENTOS EM IDOSAS PARTICIPANTES DA UNIVERSIDADE PARA A TERCEIRA IDADE

A presente dissertação de mestrado abordou a qualidade de vida, a percepção de suporte social e o consumo de medicamentos em idosas participantes de um programa da Universidade para a Terceira Idade, no município de São Caetano do Sul - São Paulo - Brasil. O estudo objetivou descrever uma possível relação entre o perfil sociodemografico da amostra, a percepção subjetiva da qualidade de vida, a percepção subjetiva de suporte social, e o consumo de medicamentos, submetendo a testes estatísticos, um conjunto de possíveis relações entre as características sociodemográficas, percepção de qualidade de vida, percepção de suporte social e consumo de medicamentos. Utilizou-se o método descritivo exploratório, de corte transversal, e de caráter quantitativo. Os dados foram coletados entre os meses de agosto a outubro de 2014, através de uma amostra de conveniência, formada por 150 mulheres, com idade média de 66,13 anos. Foram utilizados instrumentos autoaplicáveis: WHOQOL-OLD e WHOQOL-BREF (Word Health Organization Quality of Life Instrument); Escala de Percepção de Suporte Social (EPSS); um questionário sobre a utilização de medicamentos de uso geral, e um questionário contendo os dados sociodemográficos. Dos resultados, 59,3% da amostra concluiu o ensino fundamental, 49,3% é casada, 79,3% não exerce atividade remunerada, e 78,7% não exerce atividades voluntárias. Apresentou boa percepção de Qualidade de Vida Global (82,90%), sendo o domínio com menor valor médio o Funcionamento do Sensório (12,56%), e maior escore médio no domínio Autonomia (14,66%). Sente segurança ao recorrer à rede de suporte social prático (53,08%), e insegurança ao recorrer à sua rede de apoio social emocional (28,88%). A prevalência do uso de medicamentos foi de 3,6%, todos prescritos, e os princípios ativos mais utilizados pertenciam aos tratamentos da hipertensão e sistema cardiovascular. Não foram evidenciadas correlações significativas relevantes entre as variáveis do estudo, do ponto de vista estatístico. Apesar de residirem em um município com elevado Índice de Desenvolvimento Humano, conclui-se que o aumento das possíveis incapacidades físicas das idosas apontam dificuldades de acesso aos recursos do ambiente, onde a amostra estava inserida. Sugere-se a criação de pesquisas e intervenções com idosas, incluindo nos programas de educação continuada, espaços para debate com o tema da finitude e o envelhecimento, bem como a realização de novos estudos de natureza qualitativa, para aprofundar o conhecimento sobre a qualidade de vida, a percepção do suporte social e o consumo de medicamentos nesta população, como também a inclusão de outros grupos sociodemográficos de idosas, em estudos longitudinais.

Relação entre desempenho funcional e indicadores de doença arterial obstrutiva periférica em idosas

The presence of peripheral arterial disease (PAD) increases the risk and vulnerability to adverse clinical outcomes in the elderly. Like this, we investigated the relationship between functional performance and indicators of PAD in elderly women. METHODS: Cross-sectional study in which 54 elderly were assessed by questionnaire mini mental state examination, Short Phisical Performance Battery (SPPB), ankle-brachial index (ABI), human activity profile (HAP) and Edinburgh questionnaire. Statistical analysis was performed using ANOVA, t test and Pearson correlation. We considered p <0.05 as significance level. RESULTS: The mean age SPPB and ABI were 69.2 (± 6.9) years, SPPB 9.42 (± 2.55) and ABI 1.04 (± 0.14). The prevalence of PAD was 16.3%. There was a significant correlation between ABI and gait speed (r = 0.75, p = 0.001) and between PAH with SPPB (p = 0.001). CONCLUSIONS: It is suggested that the decline in functional performance in older, expressed in gait velocity component of the SPPB, is related to the presence of PAD

Riskfaktorer och förebyggande omvårdnadsåtgärder för UVI hos äldre kvinnor : En litteraturöversikt

Bakgrund: Urinvägsinfektion (UVI) är en av de vanligaste infektionerna hos äldre kvinnor. Escherichia coli (E-coli) är den vanligaste bakterien vid UVI. Äldre kvinnor lider när de är drabbade av UVI och det är sjuksköterskans uppgift att bland annat förebygga sjukdom och lindra lidande. Syfte: Att beskriva riskfaktorer och förebyggande omvårdnadsåtgärder mot UVI hos äldre kvinnor. Metod: Litteraturstudie, med databassökning genom databaser speciellt inriktade på vård och omvårdnad, CINAHL, PubMed, WEB OF SCIENCE och Medline. 15 artiklar har använts till resultatet. Resultat: Recidiverande UVI, diabetes, urininkontinens, smittspridning och förstoppning är riskfaktorer att drabbas av UVI. God hygien och regelbunden tillförsel av vätska ses som god evidensbaserad omvårdnadsåtgärd mot UVI. Ökad tillförsel av vätska förkastas, Tranbärstillägg behöver ytterligare forskning. Slutsats. Hög hygieniskstandard genom de basala hygienrutinerna är en viktig förebyggande åtgärd mot UVI.

Récits du vieillir « actif » et de la citoyenneté au quotidien : l’expérience des femmes aînées au Québec

Taken as a policy framework, active aging ranks high on most supranational bodies’ agenda. The new political economy of aging portrays “active” citizenship amongst seniors as a key challenge for the years to come. Our research focuses on, first, elderly women’s everyday ‘active’ practices, their meaning and purpose, in the context of Quebec’s active aging policy framework; and second, their day-to-day practical citizenship experiences. Informed by discourse analysis and a narrative approach, the life stories of women 60 to 70 years of age allowed for the identification of a plethora of distinctive old age activity figures. More specifically, four activity figures were identified by which respondents materialize their routine active practices, namely: (1) paid work; (2) voluntary and civic engagement; (3) physical activity; and (4) caregiving. Set against Quebec’s active aging policy framework, these patterns and set of practices that underpin them are clearly in tune with government’s dominant perspectives. Respondents’ narratives also show that active aging connotes a range of ‘ordinary’ activities of daily living, accomplished within people’s private worlds and places of proximity. Despite nuances, tensions and opposition found in dominant public discourse, as well as in active aging practices, a form of counter-discourse does not emerge from respondents’ narratives. To be active is normally the antithesis of immobility and dependence. Thus, to see oneself as active in old age draws on normative, positive assumptions about old age quite difficult to refute; nevertheless, discourses also raise identity and relational issues. In this respect, social inclusion issues cut across all active aging practices described by respondents. Moreover, a range of individual aims and quests underpin activity pattern. Such quests express respondents’ subjective interactions with their social environment; including their actions’ meaning and sense of social inclusiveness in old age. A first quest relates to personal identity and social integration to the world; a second one concerns giving; a third centers on the search for authenticity; whereas the fourth one is connected to a desire for freedom. It is through the objectivising of active practices and related existential pursuits that elderly woman recognize themselves as active citizens, rooted in the community, and variously contributing to society. Accordingly, ‘active’ citizenship experiences are articulated in a dialogic manner between the dimensions of ‘doing’, ‘active’ social practices, and ‘being’ in relation to others, within a context of interdependence. A proposed typology allows for the modeling of four ‘active’ citizenship figures. Overall, despite the role played by power relations and social inequality in structuring aging experiences, in everyday life ‘old age citizenship’ appears as a relational process, embedded in a set of social relations and practices involving individuals, families and communities, whereby elderly women are able to express a sense of agency within their social world.

Participação Social e Redes Sociais Pessoais de Idosos

Objetivo: O objetivo central deste estudo é caracterizar as redes sociais pessoais de indivíduos com idade igual ou superior a 65 anos, a nível estrutural, funcional e relacional-contextual, analisando-as segundo o nível de participação social dos idosos ao longo da sua vida em estruturas comunitárias ligadas ao lazer, cultura, desporto, religião e voluntariado. Metodologia: Para a avaliação das variáveis em estudo foram utilizados o Instrumento de Análise da Rede Social Pessoal, versão para idosos (IARSP – Idosos) (Guadalupe, 2010; Guadalupe & Vicente, 2012) para avaliar as dimensões da rede social pessoal, um questionário para caracterizar as variáveis sociodemográficas e a participação social e a Satisfaction With Life Scale – SWLS (Diener, 1985) que permite avaliar o grau de satisfação com a vida. Participantes: A amostra é constituída por 567 idosos, com uma média de idades de 75 anos (DP=7,6), entre os 65 anos e os 98 anos, maioritariamente do sexo feminino (63,0%), casados ou em união de facto (53,7%) e com escolaridade (69,8%), sobretudo ao nível do quarto ano (51,3%). A maioria dos idosos inquiridos não vive só (79,4%) numa zona de residência maioritariamente inserida em aglomerado populacional em região rural (57,0%) e não usufrui de qualquer tipo de apoio de resposta social (75,5%). Resultados: A amostra divide-se entre os que participaram comunitariamente ao longo da vida (47,8%; n = 271) e os que não participaram (52,2%; n = 296), sendo que entre os que participam 16,7% fazem-no com elevada frequência. Os idosos do sexo feminino, com idade igual ou inferior a 75 anos, casados, com habilitações literárias e que vivem acompanhados, são os que têm uma maior probabilidade de ter uma participação social mais ativa. Os idosos que apresentam participação social têm uma rede maior, com um membro a mais em média (M = 8,52 vs. 7,51, p = 0,027), e uma composição distinta dos que não participam, com menor peso das relações familiares (M = 72,61% vs. 80,81%, p < 0,001), maior peso e mais relações de amizade (M = 15,43% vs. M = 9,24%, p < 0,001) e maior presença de relações de trabalho (M = 1,11% vs. 0,13%, p = 0,006). Relativamente às características funcionais, podemos constatar que a reciprocidade de apoio é percebida como maior (p = 0,010) entre os idosos que participam comunitariamente, não se verificando diferenças noutras variáveis funcionais e relacionais-contextuais. O nível de participação e a satisfação com o nível de participação correlacionam-se positivamente com a satisfação percebida com a vida (p < 0,001). Conclusão: As conclusões apontam para um efeito da participação social ao longo da vida em estruturas comunitárias nas características estruturais das redes sociais pessoais dos idosos, não se verificando interferência na maioria das características funcionais e nas relacionais-contextuais. Verificámos ainda que há uma associação entre a participação social e a satisfação com a vida, sendo mais satisfeitos os que participam em estruturas comunitárias. É possível constatar que a rede daqueles que referem ter participação social é tendencialmente maior e heterogénea na composição, quando comparada com as redes dos sem participação social, assumindo, assim, relevância na estruturação de uma rede mais diversa e ampla, devendo ser estimulada no sentido de promover uma rede com recursos potencialmente positivos e um envelhecimento mais ativo. / Objectives: The central objective of this study is to characterize the personal social networks of the elderly, aged 65 years or more, analyzing them according to the level of social participation throughout their life in community structures related to leisure, culture, sports, religion and volunteering. Methodology: For the evaluation of the variables we used the Social Network Analysis Tool (IARSP-elderly) (Guadalupe, 2010; Guadalupe Vicente, 2012) to assess the dimensions of the social network; a questionnaire to evaluate social participation; and the Satisfaction With Life Scale SWLS – (Diener, 1985) to acess the degree of satisfaction with life. Participants: The sample consists of 567 elderly, with an average age of 75 years old (SD = 7,595), between 65 and 98 years old, mostly female (63.0 %), married (53.7%) with education (69.8%), mainly with the 4th grade (51.3%). Most of the respondents do not live alone (79.4%) in agglomerations in rural region (57.0%) and are not users of social services (75.5%). Results: The sample is divided between those who had community participation throughout life (47.8 %; n = 271) and those who did not participated (52,2%; n = 296). Between the first, 16.7% do it with high frequency. The elderly women, aged less than 75 years old, married, with educational qualifications and living not alone, are those who have a higher likelihood of having a more active social participation. The elderly that present social participation have a larger network, with one more member (M = 8,52 vs. 7,51, p = 0,027), and a composition distinct from not participating, with less proportion of family relations (M = 72,61% vs. 80,81%, p < 0,001), greater proportion and more friendships (M = 15,43% vs. M = 9,24%, p < 0,001) and greater presence of working relations (M = 1,11% vs. 0,13%, p = 0,006). Regarding the functional dimension, the reciprocity of support is perceived as higher (p = 0.010) among seniors participating in community and there were no differences in other functional and relational-contextual variables. The level of participation and satisfaction with the level of participation correlate positively with perceived satisfaction with life (p <0.001). Conclusion: The findings point to an effect of lifelong social participation in community in structural characteristics of personal social networks of the elderly, not verifying interference in most of the functional and the contextual-relational characteristics. We have also found that there is an association between social participation and life satisfaction, being more satisfied when they participate in community structures. The social network of the elderly who reported having social participation tends to be larger and heterogeneous in composition compared with those without social participation, thus assuming importance in structuring a more diverse and extensive network, should be encouraged in order to promote a network with potentially positive resources and a more active aging.

Education at last! Taiwanese grandmothers "go to school"

Language socialization is a life-long process in which individuals are continuously socialized into new roles, statuses, and practices. This process becomes more complex in multilingual contexts. However, we know little of the language socialization of older adults and we know even less of minority-speaking elders' experiences of linguistic marginalization in contemporary communicative milieus. In this ethnographic and discourse-analytic study, I examine the language socialization of non-Mandarin-speaking elderly Taiwanese women in senior adult education programs in a rural township in Taiwan. Through examining autobiographical narratives, master narratives about elders, and classroom discourses, this study explores the historical construction of their sociolinguistic marginalization and their negotiation and resistance of such marginalization. The majority of the elderly women were denied education when they were young. Some received Japanese education during the Japanese colonization period. While the uneducated and illiterate elders have a strong aspiration for learning, they are dismissed as "unable to learn" by their teachers, peer students, and community leaders. By contrast, the Japanese literate exhibit a strong learning identity associated with colonial modernity. These two groups, however, have to contend with the social stereotype associated with their non-Mandarin speaking status. Under a Mandarin-only ideology that links Mandarin with modernity, discourses that have actively mobilized the category of “illiterate” to reference the older population are part and parcel of Taiwan’s modern identity. By demonstrating how these women are treated, in official discourses and in classroom interactions, as children for their lack of Mandarin abilities, I argue that the literacy education that set out to “compensate” these women for their earlier lack of educational opportunity has paradoxically reinforced their marginalization. Further, in recent years, they have become even more marginalized as the government has prioritized the education of recent young female marriage immigrants from Southeast Asia, who are considered in charge of educating the “future sons and daughters of Taiwan.” This research demonstrates how language socialization is a contested and life-long process and calls attention to the effects of language ideologies on literacy and language education. The findings have policy implications for improving literacy and language education both within Taiwan and elsewhere in the world.

Bem-estar subjetivo em idosas com e sem cancro da mama em remissão

O aumento exponencial da população idosa e da sua esperança média de vida em consonância com o aumento da incidência do cancro da mama nesta faixa etária constituem uma problemática a nível mundi al. Objetivos: Averiguar se os dois grupos amostrais de idosas, com e sem cancro da mama em remissão, apresentam diferenças significativas nos totais de Bem - Estar Subjetivo (BES) e das suas dimensões afetiva e cognitiva. Método: A amostra é composta por 38 7 idosas, não institucionalizadas, com idades compreendidas entre os 75 e os 100 anos ( M = 85,27; DP = 6,59; intervalo 75 - 100) e que foram distribuídas em dois grupos: com cancro da mama em remissão e sem cancro da mama. Foram aplicados o questionário demo gráfico foi aplicado, a Escala de Satisfação com a Vida (ESV) e a Escala de Afeto Positivo e de Afeto Negativo (PANAS). Resultados: O grupo com cancro da mama em remissão apresentou resultados médios da escala e subescalas de BES superiores aos resultados médios do grupo sem cancro da mama, principalmente na subescala dos Afeto Positivo (AP). Estas diferenças foram estatisticamente significativas. Conclusão: Apesar do diagnóstico do cancro da mama representar uma ameaça importante ao BES das idosas, estas p articipantes apresentaram um total significativamente mais elevado o que as restantes.

Protective effect of Rhizoma drynariae extract on osteoporosis in ovariectomized rat model

Purpose: To investigate the therapeutic effect of Rhizoma drynariae extract (RDE) on ovariectomyinduced osteoporosis in rats. Methods: Female Sprague-Dawley rats were randomly assigned to a sham-operated group (control) and five ovariectomy (OVX) subgroups: OVX with vehicle (OVX), OVX with 17ß-estradiol (E2, 25 μg/kg/day), and OVX with RDE doses (40, 80, and 160 mg/kg/day). Daily oral administration of E2 or RDE started 4 weeks after OVX and lasted for 16 weeks. The bone mineral density (BMD) of the L4 vertebrae and right femurs was estimated. The length of each femur was measured with a micrometer gauge, and the center of the diaphysis determined. Three representatives L4 vertebrae were selected to evaluate the trabecular microarchitecture. Serum alkaline phosphatase (ALP), urinary calcium (U-Ca), urinary phosphorus (U-P), urinary creatinine (Cr) and osteocalcin (OC) levels were measured. Results: The study showed that high-dose of RDE significantly inhibited the bone mineral density (BMD) reduction of L4 vertebrae (0.20 ± 0.02 g/cm3, p < 0.05) and femurs (0.18 ± 0.02 g/cm3, p < 0.05) caused by OVX and prevented the deterioration of trabecular microarchitecture (p < 0.05), which were accompanied by a significant decrease in skeletal remodeling (p < 0.05) as evidenced by the lower levels of bone turnover markers. High-dose of RDE improved morphometric parameters, namely, Tb-N (3.8 ± 0.2 mm, p < 0.05), Tb-Th (0.083 ± 0.011 mm, p < 0.05) and Tb-Sp (0.19 ± 0.01 mm, p < 0.05) in L4 vertebrae significantly. The present study indicates that the administration of RDE at higher doses over a 16-week period can prevent OVX-induced osteoporosis in rats without hyperplastic effects on the uterus. Conclusion: Thus, RDE is a potential natural alternative for postmenopausal osteoporosis treatment in elderly women.

Anti-osteoporosis effect of Cistanche deserticola Ma extract in ovariectomized rats

Purpose: To investigate the therapeutic effects of Cistanche deserticola Ma. extract (CDME) on ovariectomy-induced osteoporosis in rats. Methods: Female Sprague-Dawley rats were randomly assigned to a control group and five ovariectomy (OVX) subgroups, that is, OVX with vehicle (OVX), OVX with 17ß-estradiol (E2, 25 μg/kg/day), and OVX with CDME doses (40, 80, or 160 mg/kg/day). Daily oral administration of E2 or CDME started 4 weeks after OVX and lasted for 16 weeks. Bone mineral density (BMD) of L4 vertebrae and right femur of rats was estimated, The length of each femur was measured, and biochemical analysis of serum and urine specimens were performed. Results: CDME dose-dependently inhibited the reduction in BMD of L4 vertebrae (0.23 ± 0.02 g/cm3, p < 0.05) and femurs (0.20 ± 0.03 g/cm3, p < 0.05) caused by OVX and prevented the deterioration of trabecular microarchitecture (p < 0.05), which were accompanied by a significant decrease in skeletal remodeling (p < 0.05) as evidenced by the lower levels of bone turnover markers. Conclusion: This study indicates that CDME prevents OVX-induced osteoporosis in rats, and could be used for treating osteoporosis in elderly women.
