Programas de exercícios físicos e níveis de biomarcadores inflamatórios em mulheres com distúrbios metabólicos: uma revisão sistemática

Uma grande quantidade de informações dá suporte à relação existente entre inatividade física e processos inflamatórios latentes em distúrbios metabólicos. O objetivo deste trabalho foi acessar criticamente o corpo de evidências existentes na literatura sobre a associação entre programas de exercícios físicos e os níveis de biomarcadores inflamatórios em mulheres entre 18 e 82 anos de idade. Foram realizadas buscas bibliográficas sistemáticas usando as bases de dados PubMed Medline, Cochrane Central Register of Controlled Trials, Web of Science, LILACS e SciELO de publicações entre janeiro de 1993 e janeiro de 2012 usando os seguintes termos: inflamação, citocinas, exercícios, treinamento físico, treinamento aeróbico, treinamento cardiovascular, treinamento de força, treinamento contra resistência, treinamento intervalado, reabilitação cardíaca e gerenciamento/modificação terapêutica de estilo de vida. Do total de estudos incluídos na revisão, três deles reportaram mudanças não significativas nos níveis de biomarcadores inflamatórios, um estudo documentou um aumento nos biomarcadores e 12 estudos reportaram decréscimos nos níveis de biomarcadores inflamatórios associados com exercício. Características secundárias do estilo de vida, como trabalho físico extenuante e fumo, afetaram os níveis de biomarcadores inflamatórios. Intervenções integrativas incluindo dieta, exercício aeróbico moderado (60% a 80% da frequência cardíaca máxima ou 50% a 60% do VO2Máx), treinamento contra resistência em circuito (8 a 10 exercícios, 8 a 12 repetições), aconselhamento e educação voltados para a saúde, usados conjuntamente, se apresentaram como possíveis estratégias efetivas na melhoria nos níveis de biomarcadores inflamatórios em mulheres

Histórias de idosos: sementes para cultivarmos uam educação para uma velhice bem-sucedida

We understand that the successful old age is not confined only in the analysis of quantitative aspects concerning the economic situation of the subject that gets old, but this special way of aging is related to other values, such as dignity, happiness, self-esteem, willingness, autonomy, independence, social involvement with family and friends, among others. Thus, this study aimed to investigate the human aging process, considering the history of life of ten seniors who fit the profile of successful old age, seeking to identify elements that contribute to educational thinking in order to get a successful aging. In this perspective, we argue in this study, the idea that we need to learn to engage in experiences that more than providing satisfaction and well-being in the moment in which we conducted, serve as a potentiating to a successful old age. Thus, throughout this thesis we question: what are the present indicative in the histories of life of elderly people, considered successful, which may contribute to an education that people experiencing their age more satisfactorily. This is a qualitative study, that took as universe a methodological oral history, in which we used as a technique of research a semistructured interview as a part of their life history, with emphasis on consideration of the following categories: diary routine, with emphasis on social harmony in the family, at work and in friendship groups of leisure and physical activity, self-knowledge and the learning experiences throughout life. To get the objectives outlined, as well as lectured on the categories analyzed, we support our reflection on the theory of the course of life, which includes human aging as a historical and cultural contextual reality. Our research revealed, among other things, that successful aging is coupled to an active lifestyle, where the involvement in physical activities, recreational and social experiences throughout life is important for increasing self-esteem, autonomy and joy of living, conditions that enable successful old age. Our study also revealed that the educationfor successful old age is linked with the consumption along the life, educational activities which broaden the possibilities of social interaction between people, even among different generations, since the interaction is important to learn and accept our possibilities and limits.

Influência da atividade e inatividade física na composição corporal e adiposidade central

To analyze influences of the physical activity and sedentary behaviors on indicators of both central and total body fat in male adolescents. Cross-sectional study with 60 male students of age range from 11 to 14 years old. It were evaluated the body mass, height, triceps skinfold, waist circumference, body fat percentage (bioelectrical impedance) and the physical activity level through questionnaire. The physical inactivity prevalence was of 35%, and the excessive total and central body fat were observed in 38.3% and 48.3% of the sample, respectively. There was association of the sedentary behaviors with the excessive total and central body fat (OR = 5.2 e OR = 6.4, respectively), however there was not for physical activity. The adoption of sedentary behaviors is associated at the development of the total and central obesity among male adolescents.

A Short Physical Performance Battery (SPPB) como preditora da fragilidade em idosos residentes na comunidade

Introduction: The SPPB provides information about physical function and is a predictor of adverse events in the elderly. Frailty is a multidimensional syndrome that increases susceptibility to diseases and disability. However it may be possible to prevent or postpone frailty if is identified early. Our objective is to analyze SPPB s ability in screening for frailty a community-dwelling young elderly from cities with distinct socioeconomic conditions. Methods: Data were originated from community dwelling adults (65-74 years old) in Canada (Saint Bruno; n = 60) and Brazil (Santa Cruz; n = 64). SPPB was used to assess physical performance. Frailty was defined as the presence of ≥ 3 of these criteria: weight loss, exhaustion, weakness, mobility limitation and low physical activity. One point was given for each criterion met, totalizing a frailty score ranged from 0 to 5. The Linear Regression and Receiver Operating Characteristics analyses were performed to evaluate the SPPB s screening ability. Results: Mean age was 69.48, 10.0% of the Saint Bruno s sample and 28.1% of Santa Cruz s were frail (p = 0.001), the SPPB score means were 9.6 and 8.5 respectively (p = 0.01). SPPB correlated with the frailty score (R2 = 0.33), with better results for Saint Bruno. A cutoff of 9 in SPPB had good sensitivity and specificity in discriminating frail from non frail in Saint Bruno (AUC = 0.81) but showed fair results in Santa Cruz (AUC = 0.61). Conclusion: The SPPB has moderate ability in predicting frailty among older adult s population, and is an useful test to identify people with good functionality and low frailty when SPPB scores are ≥9

Correlação entre os parâmetros do cortisol salivar e o fenótipo de fragilidade em idosos institucionalizados

Introduction: The Frailty Syndrome is characterized by the decrease of energy reserve and the reduced resistance to stressors. Studies indicate that the neuroendocrine markers can be related to the appearance of this syndrome. The main endocrine answer to stress is the increase of cortisol levels. Objective: To analyze the correlation between the frailty syndrome the salivary cortisol in elderly residing in nursing homes. Method: A traversal study was accomplished, in João Pessoa city, PB, with a sample composed by 69 institutionalized elderly. The collected data refer to the frailty phenotype (weight loss, exhaustion, slowness, weakness, and lower level of physical activity) and to salivary cortisol parameters (first measure - 6-7h; second measure - 11-12h; third measure - 16-17h). In the statistical analysis the Pearson s correlation test was used, Chi square Test and Anova and Simple Linear Regression analyses. Results: The sample was composed by 37.7% of men and 62.3% of women, with age average of 77.52 (±7.82). There was a percentile of 45.8% frail elderly. The frail elderly obtained higher cortisol values in the third measure (p=0.04) and the frailty load was significantly associated to the first measure (r=0.25, p=0.04). The simple linear regression analysis presented a determination rate (R2=0.05) between frailty load and first cortisol measure. Conclusion: The largest cortisol values in the morning and before sleeping among the frail elderly supply indications that can have a relationship of cortisol increase levels and the frailty presence in elderly from nursing homes.

Apoio social e síndrome da fragilidade em idosos residentes na comunidade

Introduction: The frailty in the elderly is the result of a complex interplay between many social and clinical factors involved in its genesis. Although there is an understanding of its association with increased risk of adverse clinical outcomes, still it is unclear whether this syndrome can be aggravated due to lack of social support. So, the objective of this study was to analyze the association between social support and frailty syndrome in elderly community residents. Materials and methods: Observational analytical cross-sectional study, with a sample of 300 elderly living in the city of Natal-RN. Were collected informations about socialdemographic, economics and physical health data. The Social support was assessed by the status of cohabitation; marital status; contact frequency and diversity rate; received and given attendance frequency rate; and Map Minimum Relations of the Elderly. The frailty was assessed using the following criteria: unintentional weight loss, weakness, low physical activity, exhaustion and Slowness. To observe any possible associations, we performed the Pearson chi-square test, the Student t test and multivariate analysis using binary logistic regression, adopting a significance level of 5%. Results: It was observed that there were no associations of frailty with the social support variables, except for housekeeping mode (p = 0.046) of the MMRI. For the sociodemographic, economic, physical health and social support data, only age (p <0.001), sedentary lifestyle (p = 0.002) and poor perceived health (p = 0.001) were the ones that remained in the logistic regression model, with strong association for the presence of frailty. Conclusion: Among the variables related to social support, only to help with housekeeping was significantly associated with frailty. However, more studies need to be developed to characterize the social vulnerability, as well as health services need to recognize the importance of social support as an integral part of care for the elderly

Prevalência e fatores associados ao risco e a desnutrição em idosos institucionalizados

One of the most important problems in the elderly is a nutritional deficiency. Several physiological changes and the use of multiple drugs interfere with appetite, food intake and absorption of nutrients, which can lead to the risk and malnutrition in the elderly, especially among institutionalized. The present study aimed to evaluate the prevalence of malnutrition and risk for malnutrition and its associated factors in institutionalized elderly. The same can be characterized by the type individual, observational and cross-sectional. Obtaining the sample was through the records of individuals of long-stay institutions for the elderly in the city of Natal, RN. The elderly were evaluated through the Mini Nutritional Assessment (MNA) and triceps skinfold (TSF) and each senior or caregiver answered a questionnaire about information like type and dietary restrictions, accessibility to food, use of alcohol and tobacco, practice physical activity and appetite. Variables such as age, gender, education, marital status, time that the elderly living in the institution, the reason for the institutionalization and comorbidities were taken from the records of each senior. The frequency of food consumption of various food groups was assessed from the questionnaire frequency of feeding study Health, Wellbeing and Aging (HWA). Data were presented as means and standard deviations, absolute and relative frequencies. To analyze the frequency of consumption, there was a factor analysis with extraction of factors from the principal components analysis with varimax rotation. A bivariate analysis was performed using the chi-square and the magnitude of the effect observed by prevalence ratio (95% CI). The Poisson regression assessed the net effect of independent variables on the two outcomes, considering a significance level of 5%. We studied twelve Homes for the Aged totaling 381 seniors eligible for the study. The prevalence of risk of malnutrition was 46.1% (45.9 to 46.2) and malnutrition was 31.4% (31.2 to 31.5). The risk of malnutrition was significantly associated with the presence of urinary incontinence (RP = 1.444, 1.113 to 1.874) was associated with malnutrition and lack of appetite (RP = 1.757, 1.246 to 2.476), the fact that the individuals do not have access to food outside the institution (RP = 0.565, 0.337 to 0.946), low water consumption (RP = 1.646, 1.101 to 2.459) and dementia (PR = 1.537, 1.072 to 2.204). The high prevalence of malnutrition and risk of malnutrition in the study suggests that we should pay attention to information related to eating habits and the presence of comorbidities, as these can influence the nutritional status of this population

Desempenho cognitivo em diferentes níveis de escolaridade de adultos e idosos ativos

OBJETIVO: Comparar o desempenho cognitivo em diferentes níveis de escolaridade de indivíduos adultos e idosos praticantes de atividade física. MÉTODOS: Foram avaliados 122 indivíduos sem comprometimento cognitivo, idade entre 46 a 85 anos e escolaridade entre 1 a 15 anos, praticantes de atividade física há mais de 6 meses no Programa de Atividades Físicas e Recreativas para a Terceira Idade. Foi aplicada uma bateria de testes cognitivos para verificar as seguintes variáveis: memória de curto prazo, linguagem, aprendizagem, taxa de esquecimento e funções executivas. RESULTADOS: O teste de Kruskal-Wallis apontou diferenças entre os grupos, com diferentes níveis de escolaridade, apenas para a memória de curto prazo, sendo que o teste de U Mann Whitney demonstra diferença entre o grupo de menor escolaridade (1-4 anos) com o grupo de maior escolaridade (> 12 anos). CONCLUSÃO: Diante disso, sugere-se que adultos e idosos ativos, em diferentes níveis de escolaridade, apresentam um perfil cognitivo semelhante para os seguintes domínios cognitivos: linguagem, aprendizagem, taxa de esquecimento e funções executivas.

Hipertensão arterial em idosos: prevalência, fatores associados e práticas de controle no Município de Campinas, São Paulo, Brasil

Este estudo teve como objetivo avaliar a prevalência da hipertensão arterial referida em idosos de Campinas, São Paulo, Brasil, identificando os fatores associados, o uso de serviços de saúde e o conhecimento e as práticas quanto às opções do tratamento. Trata-se de estudo transversal, de base populacional, com amostra de conglomerados, estratificada e em múltiplos estágios. A análise dos dados referentes aos 426 indivíduos (sessenta anos e mais) levou em conta o desenho amostral e o efeito do delineamento. A prevalência de hipertensão foi de 51,8% (46,4% nos homens e 55,9% nas mulheres) e mostrou-se mais elevada em idosos: com menor escolaridade (55,9%), migrantes de outros estados (60,2%) e com sobrepeso ou obesidade (57,2%). Os resultados indicam que os serviços de saúde estão garantindo o acesso ao atendimento médico (71,6% visitam o médico regularmente) e aos medicamentos (86,7% tomam medicamento de rotina), sem distinção de nível sócio-econômico. Persistem, no entanto, desigualdades sociais quanto ao conhecimento e utilização de outras práticas de controle da pressão arterial, como dieta adequada e atividade física, que são insuficientemente utilizadas também pelos segmentos socialmente mais favorecidos.
