The population aging process increases the number of elderly people worldwide. In Brazil, a country of continental size, this process began in the 40s and happens with specific features in each of the different region s realities. This way, this thesis aimed to evaluate the psychometric properties of a elderly s quality of life (QOL) scale, the WHOQOL-old, in a population of the Northeast of Brazil. We sought to investigate the congruence between the content covered by the scale and the ones deemed as relevant by the participants. It aimed also study the validity evidences of the instrument s internal structure. To achieve the research objectives we adopted the design of multiple methods. The research was organized in two studies. For data collection, both studies used a sociodemographic questionnaire to obtain a profile of the participants and the Mini Mental State Exam (MMSE), used as exclusion criterion. A number of 18 elderly residents of the cities of Natal-RN and Campina Grande-PB, mean age of 73.3 years (SD = 5.9) took part od the study, They were organized into three focal groups (FG) in witch they discussed about the concept of QOL, what enhance and what hinders QOL. For Study II, a quantitative approach, 335 elderly from Campina Grande responded scale WHOQOL-old. They are between 65 and 99 years (M = 74.17, SD = 6.5). The FG data were analyzed by categorical thematic content. For the data analysis of the WHOQOL-old scale were used exploratory factor analysis and calculation of the Akaike and Bayesian information criteria. The results of both studies were triangulated. According to the discussions in the FG, health and social participation have central roles in quality of life. Social participation is related to all the other QOL s influences raised. The participants indicated the relevance of religiosity and were divided about the importance of sexual activity. Exploratory factor analysis (EFA) extracted a model of six factors. Two items (OLD_3 and OLD_9), not loaded on any factor and were excluded. The other items had factor loadings > 0.3. The response categories were reduced from five to three. After the scale changes, the empirical model showed better fit (-2loglikelihood = 8993.90, BIC and AIC = 9183.90 = 9546.24) than the theoretical model (-2loglikelihood = 18390.88, AIC = 18678.88 and BIC = 19228.11). Despite the best information criterion values, the RMESA remained above the ideal (0.06). We conclude that the WHOQOL-old presents psychometric parameters below the ideal when used with the Northeast population, but the improvements made the scale s use acceptable. The WHOQOL-old uses observable variables that matches with the participants' perceptions on quality of life. However, new strategies must be tested for a better sacale refinement

In view of the evident increase in the population group of people over 60 years old, the aging process has raised important discussions on social, political and economical planning that recommend that the increase in longevity must be followed by autonomy and well-being. Faced to these demands, the literature reports that physical activity is a key strategy to promote better living conditions for the elderly. Studies about personenvironment are making efforts to understand the socio physical environment role to encourage old people to make activities in many different environments. Among these, the urban public open space has been reported by many researches as a promising alternative in order to adopt a less sedentary life style. Based on these considerations, this study proposed to investigate the relationship between the social environment support elements and social interaction of seniors in public squares in the city of Natal, RN, using a multimethodological approach that included a experts panel, environmental characteristics analysis of 252 squares, case studies containing collective and individual interviews with elderly users and the spatial representation of their social interactions. The association between physical activities with the socialization practiced by them was identified as the main motivation for their presence in these places. The results indicate that the relationship between the socio-environmental characteristics (concept developed in this study) and the socio-spatial behaviors that include the spatial appropriation, spatial arrangements and interpersonal distances, helps to promote social interactions in carrying out activities, which, according to the assumptions Active Ageing Program, enable the maintenance of an active way of life, with important implications for health, wellness and quality of life in old age

The circadian timing system (CTS), in rodents, consists of interconnected neural structures such as the suprachiasmatic nucleus (SCN) of the hypothalamus, Intergeniculate Leaflet (IGL) of the thalamus, synchronous pathways and behavioral effectors. The SCN has been described as the major circadian pacemaker in several species of mammals, while the IGL appears to be involved in integration of photic and non-photic clues relaying them to SCN. The CTS allows an ordered internal temporal organization to the organism, providing the proper execution of physiological and behavioral mechanisms, which brings homeostasis. However, this stability is disrupted with aging process causing numerous pathological disorders, ranging from simple loss of physiological functions to decreases in cognitive performance. Therefore, is fundamental understanding the effects of senescence in this system. In this context, is proposed in this study to check if there are changes in IGL cytoarchitecture, neurochemical and retinal afferent markers with aging and their possible morpho-functional implications. To achieve this goal wistar rats were divided into 3 groups: young (3 months); Middle Age (13 months); Old (23 months). They were submitted to paraformaldhyde (4%) transcardiac perfusion to tissue fixation. Then, they had their brain removed and sectioned in 30 µm slices, which every sixth section were collected. This sections were processed by nissl method and immunostaining for GFAP, GAD, ENK, NPY and CTb in order to analyze the IGL features. It was observed a cell loss in middle age and old animals at Nissl, NPY and CTb stains. In addition, it was shown a increase in GFAP in middle aged animals compared to young and old ones. No differences were found in other neurochemichal stains. These data suggests IGL loss retinal afferents and neurons, in special the NPY-IR ones, likely having a compensatory gliogenesis. This supports the correlations between the CTS functional deficits and an anatomical deterioration of its components with the aging process.

The aging process causes changes in the elderly’s sleep/awake standard impairing their cognitive abilities, particularly executive functioning, which already suffers loss by aging. The literature suggests that executive function and preserved sleep quality are key to maintaining good quality of life and independence of older people, requiring interventions to minimize the impact of losses incurred by the aging process. This study evaluated the effect of a cognitive training program and sleep hygiene techniques for executive functions and sleep quality in healthy older people. The participants were 41 healthy older adults, of both sexes, who were randomly divided into four groups: control group [GC], cognitive training group [GTC], sleep hygiene group [GHS] and training group + hygiene [GTH]. The research was developed in three stages: 1st - initial assessment of cognition and sleep; 2nd - specific intervention to each group; 3rd - post-intervention revaluation. The results showed that GTC had significant improvements in cognitive tasks flexibility, planning, verbal fluency and some aspects of episodic memory, besides gains in sleep quality and decrease on daytime hypersomnolence. The GHS improved sleep quality and daytime sleepiness as well and had significant improvements in insights capacity, planning, attention and in all evaluated aspects of episodic memory. The GTH had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. The CG showed significant worsening in excessive daytime sleepiness in capacity planning. Thus, we conclude that cognitive training interventions and sleep hygiene strategies are useful in improving cognitive performance and quality of healthy elderly sleep.

In the context of current capitalist society, marked by the logic that restricts the human person their status as workforce, in order to generate profits, old age is often treated as an underprivileged life stage. This reality becomes more intense considering the sharp aging process that affects brazilian society is accompanied by the country's entry into a globalized world and tensioned by the dictates of capital. Thus, despite the increasing development of policies to strengthen the guarantee of elderly rights, it is necessary to establish effective strategies of these measures to ensure a higher quality of life to these subjects. Therefore, it is necessary to develop studies that problematize the issue of the elderly, which represent a growing portion of the population, and hence have more visible demands, including in health. With the increase in the elderly population in Brazil it is possible to realize the country is going through a demographic transition and epidemiological changes that contribute to change the landscape of health care of the elderly, especially the hospitalization. Thus, this study aimed to analyze the multiple aspects of ensuring the rights of elderly patients admitted to the State Hospital Dr. Ruy Pereira dos Santos (HRPS), located in Natal / RN, whose most patients are elderly. Specifically sought to understand the aging process, its social consequences and the vulnerability to which it is exposed, especially during the disease situation; understand the process of construction of the Brazilian public health and their actions for older people; learn the expressions of citizenship formation in Brazil with regard to policies for older people; and investigate the design of health professionals about the guarantee of the right of hospitalized elderly. Starting from an integrated coordinated theoretical and practical possibilities, a qualitative research and literature character, documentary and field was held. For this, there were four semi-structured interviews with health research locus Hospital professionals - namely, two social workers, a doctor and a nurse - as well as life stories with the hospitalized elderly patients, one in each deck the said Hospital, totaling three. The results pointed to the difficulty of health policy become effective as law and stressed one historical scenario violation of the rights of elderly hospitalized patients, which persists due to the precarious situation and the difficulty of effective implementation of the Unified Health System (SUS ) and other public policies to that end.

The present study regards an applied qualitative social research (descriptive) which approaches the matter between old age and Brazilian social actions performed in social projects, aiming a qualified life and citizenship for this group of age. The objective of the study is to evaluate the contribution of Project Health and Citizenship in Old Age regarding social actions from the government directed to old age individual treatment for life quality improvement. The theoretical fundamentals of this work is, in a first moment, about old age and certain existing theories about aging process, as well as the differences and perspectives that come up throughout this process. In a second moment, some reflections are developed about the relation between life quality and leisure regarding old age, with the conception and historical rescue about these questions, as well as the evidence of leisure as an instrument of well-being feasibility and a better life quality in old age. Then the study contextualizes Brazilian government treatment to old age individuals, cutting off the Constitution of Republic from 1988 and some social attitudes taken by the government in a try to reach this specific group. Finally, the study presents the Project Health and Citizenship in Old Age , as a social program which belongs to extension activities from Federal Center of Technological Education of Rio Grande do Norte (CEFET-RN), which aims old age treatment and their citizenship and life quality. After the application of a semi-structured interview using the technique of Analysis of content for the Analysis and Discussion of Results, it is possible to conclude that the Project Health and Citizenship in Old Age fulfils its objective regarding contribution, through offered leisure activities, for old age well-being and life quality improvement. Hence, on this regard, it is possible to observe the importance and value of government actions, social projects and programs assisting old age individuals, for they are able to provide this group the opportunity to live out activities that allow their citizenship and socialization, regarding well-being and life quality improvement.

This thesis concerns the study of the city and impacts that will be caused in its structure due to the aging process of the human society, mainly in Brazil. The most important focus will be those related to problems of accessibility, leisure, housing, health and labor, issues that most affect people over 60 years of age. Beyond the analysis of inherent problems to the subject, proposals will be made for urban intervention that the cities become more suitable for the living of the elderly. To support this study, a review of different theories about the city was carried out, then a panel about the presence of the elderly in society, including Brazil, and in the cities, aiming at a vision, as broad as possible, on how the elderly were treated throughout history. In order to establish paradigms and parameters in the approach to the subject, a series of systematic observations on the urban space in different cities proceeded, in Brazil and abroad, with works aiming the inclusion of the elderly in urban areas, such as Amsterdam, Barcelona, Brasilia, Luanda and Rio de Janeiro, a city considered by the UN as physical and territorial urban laboratory suitable for the elderly. From there we tried to obtain, in addition to literature and observation of other countries experiences, the conduct of field research and official standards analysis, the theoretical basis for establishing guidelines on how to plan and design a more appropriate urban space for the elderly
