O transporte como determinante social de saúde : mobilidade e utilização de transportes públicos na perceção das pessoas idosas : um estudo de caso numa comunidade urbana

RESUMO - O crescimento da população idosa constitui um dos principais desafios para as atuais e futuras sociedades. A possibilidade de as pessoas permanecerem na sua comunidade de forma saudável e ativa, à medida que envelhecem, elevam a importância da questão da mobilidade e da forma como se deslocam, na saúde e qualidade de vida desta população. O presente trabalho propôs-se perceber de que forma o acesso a transporte influencia a saúde e qualidade de vida, na perspetiva das pessoas idosas e identificar fatores que atuassem como barreiras ao acesso e utilização de transportes, principalmente transportes públicos. A metodologia utilizada foi estudo de caso, com base no modelo PRECEDEPROCEED, desenvolvido na Ameixoeira, Lisboa. Os dados resultaram de um questionário aplicado a 24 pessoas idosas, da análise documental e da realização de entrevistas. A análise dos dados sugere que, é ao nível da autonomia e independência que o acesso a transporte influencia a saúde e a qualidade de vida da amostra, e a mobilidade e utilização de transporte, por sua vez, é influenciada por fatores individuais, como a idade, o género, o rendimento e as condições de saúde, e fatores ambientais envolvendo características dos transportes e da zona de residência. Tendo-se focado o trabalho na identificação das barreiras percecionadas pelas pessoas idosas na utilização de transportes públicos, sugere-se o elevado preço, a insuficiente distribuição do serviço, a distância às paragens e os horários inadequados como os principais constrangimentos identificados. Embora os resultados não possam ser extrapolados, devem ser encarados como um ponto de partida para futuras investigações.

Interação do planeamento urbano com o envelhecimento ativo : percepção de acessibilidade pedonal dos adultos de 65 ou mais anos residentes no município de Setúbal

RESUMO - Introdução- O envelhecimento populacional expressa crescentes necessidades sociais e em saúde num sistema que se encontra em sobrecarga. Considerando que o meio envolvente influencia as atitudes e o estado de saúde dos indivíduos, é extremamente importante analisar as características físicas que, da perspetiva dos utilizadores, influenciam comportamentos determinantes para o seu bem-estar e qualidade de vida. Esse conhecimento traduz-se na planificação de estratégias adequadas às necessidades desta população mais vulnerável, inibindo iniquidades, estimulando a autonomia dos indivíduos e, prevenindo necessidades de cuidados de saúde. Objetivos- Conhecer qual a acessibilidade pedonal percebida por indivíduos de 65 ou mais anos, residentes no município de Setúbal e avaliar o grau de correlação existente entre a acessibilidade pedonal percebida e a qualidade de vida associada à saúde. Metodologia- Foi utilizada metodologia descritiva, observacional e transversal, tendo sido aplicados 3 questionários (PAP+65, EQ-5D e questionário de caracterização da população), aplicados por hetero-preenchimento. Resultados- Da aplicação do coeficiente de correlação de Spearman, observou-se presença de associação estatisticamente significativa entre a acessibilidade pedonal percebida e a qualidade de vida associada à saúde (0,219, para p <0,01). Após dicotomização dos resultados do total da escala PAP+65, verificou-se que 55,6% dos participantes consideram que existe elevada adequabilidade do seu bairro para caminhar, no município de Setúbal. Conclusão- Os resultados demonstraram objetivamente que a perceção da acessibilidade do bairro para caminhar tem associação com a qualidade de vida relacionada com a saúde, o que sugere que medidas que melhorem a acessibilidade pedonal para a população de maior idade traduzir-se-ão em ganhos em saúde para esta população.

A+ grandparents at school

Facing an aging society, where there is a large gap between generations and where the elderly are neglected, the Portuguese Red Cross – Delegation of Vila Nova de Gaia – created the project A+: grandparents at school, which encourages intergenerational work. After observing the positive results of the pilot project, the A+ team decided that the project has the potential to be scaled at a national level to enable it to contribute to the integration of the older people in the society, as well as for positive changes of individuals with regard to the elderly. This work project proposes a method to determine whether A+ can be scaled and what is the most efficient way to do it, establishing a process of scale that can be used by every non-profit organization

Versão portuguesa do CANE (Camberwell Assessment of Need for the Elderly) : desenvolvimento e dados preliminares

RESUMO - A avaliação de necessidades de cuidados é crucial no planeamento, monitorização e avaliação de serviços de psiquiatria e saúde mental, bem como na investigação e na clínica. Este princípio é obviamente aplicável aos serviços responsáveis por populações de pessoas mais velhas. O instrumento CANE — Camberwell Assessment of Need for the Elderly possibilita uma avaliação consistente das necessidades de utentes idosos, nomeadamente em situações de patologia neuropsiquiátrica. Procede-se a uma avaliação cruzada, entrevistando a pessoa em questão, o seu cuidador informal e o técnico responsável. Esta avaliação multidimensional abrange domínios da esfera biológica, psicológica e social, sendo aplicável na comunidade ou em internamento (regime parcial ou completo). A utilidade do CANE tem sido evidenciada em contextos clínicos, de investigação e de avaliação de serviços. Existem múltiplas traduções a nível internacional, a maioria das quais validada. Na área da epidemiologia psiquiátrica nem sempre estão disponíveis os dados relativos à qualidade das adaptações de instrumentos, pelo que se apresenta o processo de desenvolvimento da versão portuguesa (de acordo com as regras para validação transcultural, no processo de tradução-retroversão). A aplicabilidade da versão portuguesa foi satisfatória neste estudo-piloto, representando a primeira fase de um trabalho multicêntrico nacional. Nesta fase inicial, foram considerados casos de idosos com patologia neuropsiquiátrica (maioritariamente demência — 71,4%), em dois centros (Lisboa e Porto) (n = 21). A média de idades foi 73,9 (± 6,3) anos, sendo 76,2% do sexo feminino. A maioria vivia em casa, apresentava co-morbilidade somática e estava em contacto com um cuidador informal (em geral, familiares do sexo feminino). Os avaliadores identificaram necessidades, nem sempre cobertas, nas seguintes dimensões: cuidados com a casa, alimentação, actividades diárias, memória, saúde física, sofrimento psicológico, companhia e dinheiro/economias. Nem sempre a perspectiva de doentes, cuidadores, técnicos e avaliadores foi inteiramente coincidente. Estes resultados preliminares da aplicação da versão portuguesa do CANE são consistentes quanto à sua validade ecológica, facial e de conteúdo, estando em curso contributos adicionais para a validação efectiva numa amostra de maior dimensão.

The effect of a weighted-vest strength and balance training program on obstructed walking in postmenopausal women

SUMMARY Background: Age related declines in lower extremity strength have been associated with impaired mobility and changes in gait patterns, which increase the likelihood of falls. Since community dwelling adults encounter a wide range of locomotor challenges including uneven and obstmcted walking surfaces, we examined the effect of a strength 11 and balance exercise program on obstructed walking in postmenopausal women. Objectives: This study examined the effect of a weighted-vest strength and balance exercise program on adaptations of the stance leg during obstacle walking in postmenopausal women. Methods: Eighteen women aged 44-62 years who had not engaged in regular resistance training for the past year were recruited from the St. Catharines community to participate in this study. Eleven women volunteered for an aerobic (walking), strength, and balance training program 3 times per week for 12 weeks while 7 women volunteered as controls. Measurements included: force platform dynamic balance measure of the center of pressure (COP) and ground reaction forces (GRFs) in the stance leg while going over obstacles of different heights (0,5, 10,25 and 30 cm); and isokinetic strength measures of knee and ankle extension and flexion. Results: Of the 18 women, who began the trial, 16 completed it. The EX group showed a significant increase of 40% in ankle plantar flexion strength (P < 0.05). However, no improvements in measures of COP or GRFs were observed for either group. Failure to detect any changes in measures of dynamic balance may be due to small sample size. Conclusions: Postmenopausal women experience significant improvements in ankle strength with 12 weeks of a weighted-vest balance and strength training program, however, these changes do not seem to be associated with any improvement in measures of dynamic balance.

Our future in geriatrics : an examination of the knowledge, attitudes and career choices of physical therapy students in Ontario : a pretest-posttest study /

There continues to be a shortage of health professionals interested in providing care for the older adult. Part of the problem seems to stem from the negative perceptions of geriatrics as a clinical speciality. This study examines the knowledge, attitudes and career decisions of physical therapy students in Ontario before and after an educational intervention. Surveys were conducted with 144 physical therapy students from five universities before and after their geriatrics course in order to measure their knowledge, attitudes and interest in working with older adults. The incoming class of physical therapy students (n = 1 86) acted as control subjects for the study. The Revised Palmore Facts On Aging Quiz measured the students' knowledge of aging (Miller & Dodder, 1980). The Revised Tuckman-Lorge (Axelrod & Eisdorfer, 1961) and the Kogan Old People Scales (Kogan, 1961) were used to examine attitude. An environmental scale was developed based on the work of Snape (1986) to measure the impact of the working conditions on the students' career choices. A 10-point Likert-type scale based on the work of Michlelutte & Diseker (1985) was modified and used to measure career interest in working with the elderly. On independent sample t-tests, positive attitudes were related to the demographic characteristic of gender; ethnicity was negatively related; and marital status was found to be unrelated to attitude (fi<.05). Having a relationship with an older adult and taking courses in gerontology were also found to be positively related to attitude (fi<.05). Results on a betweensubjects design which compared students before and after the course found that knowledge scores improved from pretest to posttest (fi<.05). In general, attitude scores improved from T1 to T2 on both measurement tools (b<.05). The environmental and vocational interest scales yielded statistically significant differences between the control and experimental groups during the intervention period (p<.05). The results of this research indicated that knowledge and attitudes improve after an educational intervention; however, there was little impact on the students' overall career decisions. Further research is indicated to examine the complex relationship between attitude and behaviour and its impact on students' career choices. In addition, the impact of geriatric clinical environment on students' attitudes and career decisions needs to be further explored.

Improving the oral health status of functionally independent and dependent seniors residing in long-term care facilities through dental hygiene education /

The purpose of this study was to evaluate the oral health status of residents residing in 2 long-term care facilities and determine if dental hygiene education was required in order to improve their current oral health. The oral health status of 6 independent and 4 dependent individuals residing in 2 long-term care facilities was evaluated. In addition, the current oral health and disease prevention practices employed by 4 caregivers who were responsible for providing oral care to dependent residents in the long-term care facilities were evaluated. Furthermore, an evaluation of the oral care practices of independent residents who were responsible for providing their own care was conducted. Finally, the challenges that caregivers and independent residents faced when performing oral care were determined, and methodological changes were proposed. Using a generic qualitative research methodology, data collection was comprised of semi structured interviews, field observations, and documentation. The oral health status of the residents was reevaluated 3 months later. The findings of this study demonstrated an increase in plaque accumulation, gingival inflammation, and unhealthy gingival tissue colour changes among the residents over the 3-month period. The study revealed that poor oral health among the residents was a result of inadequate oral hygiene care techniques, difficulties accessing oral health care, financial limitations, insufficient care staff, insufficient time for personal care duties, lack of professional development, minimal interprofessional collaboration of health disciplines, and lack of perseverance on the part of the caregivers and residents. Overall, oral health is essential, and maintaining optimal oral health requires increased collaboration and communication between health care providers.

Aging policy: a case study of co-ordination in Canadian governments

ABSTRACT Canada is an aging society. The number of people aged sixty-five and over is rising, while the number of people under twenty is declining. These two concurrent changes in the age structure have produced a sh~ft in the demographic composition of Canada which is commonly referred to as the aging phenomenon. Regardless of whether or not the number of people under twenty continues to decline, the number of elderly in Canada will almost double over the next twenty years. This rapidly growing elderly clientele will doubtless have an impact on Canadian governments. Federal, provincial and municipal governments are presently providing a variety of programs that have a special bearing on the aged and most senior citizens are beneficiaries of one or more of these programs. The ramifications of a rapidly growing elderly clientele are obvious. In order to cope with the impact of a significant increase in the number of elderly persons, the development and implementation of aging policy must be co-ordinated at each level of government and between and among levels of government. If aging policy is not co-ordinated, the results are likely to be: inappropriate policy decisions; duplication and overlap; and, ineffective and irresponsive services. No one benefits from these results. The need for co-ordination is apparent. The purpose of this thesis is to examine existing governmental efforts to co-ordinate policy in the field of aging. These efforts are examined by focusing on interactions directed at co-ordination between and among major actors in aging policy. A framework is used to structure the description and analysis of these interactions. The variables of formalisation and intensity and the concept of power are instrumental in analysing interactions for co-ordination. The underlying intent of this thesis is to discover some of the main gaps in existing governmental efforts to co~ordinate aging policy. Gaps are, in fact, discovered. Several explanations for the existence of gaps in interactions for co-ordination are discussed. A major hypothesis involving a relationship between a bureaucratic form of organisation and interactions for coordination is suggested. Finally, three recommendations for improving co-ordination in aging policy are offered.

Health-related learning needs and interests of selected non-institutionalized elderly

The research question in this study was "How do the noninstitutionalized elderly in the Hamilton-Wentworth Region perceive their learning needs and interests related to health?" The theoretical foundations of instruction for adults were reviewed as well as learning needs and interests in adult education, the assessment of learning needs in general, and the assessment of the learning needs of the elderly. The methodology used was a descriptive design. A research-based questionnaire-interview was developed, refined, and pilot tested. From a random sampling procedure, a participant group of 23 was secured. The questionnaireinterview was administered in a home visit situation. Data, which were collected, were coded, analyzed, processed, and printed. The results indicated that each participant had many learning needs and interests of varying intensities. The participants had many preferences in the delivery of health promotion. The learning needs and interests had several significant correlations with other variables. The implications of the result~ were discussed.

The elderly : reminiscing, coping with loss, accepting death

This study investigated loss, death and dying, reminiscing, coping and the process of adaptation from the sUbjective perspective. A number of theories and models of death and dying were reviewed in the background literature search with the focus on reminiscing as a coping phenomenon. The format of the study was audio-taped interviews with ten sUbjects and the recording of their memories and reminiscing of life stories. The sUbjects were required to complete an initial questionnaire in a demographic data collection process. Two separate interviews consisted of a primary data collecting interview and a verification interview four to eight weeks later. An independent chart review completed the data collecting process. Data analysis was by the examination of the emerging themes in the subjects' personal narratives which revealed the sUb-categories of reminiscing, loss (including death and dying), acceptance, hope, love, despair and belief. Belief was shown to be the foundation and the base for living and reminiscing. Reminiscing was found to be a coping phenomenon, within the foundation of a belief system. Both living and reminiscing revealed the existence of a central belief or value with a great deal of importance attached to it. Whether the belief was of a spiritual nature, a value of marriage, tradition, a work ethic or belief in an abstract value such as fate,it gave support and control to the individuals' living and reminiscing process. That which caused despair or allowed acceptance indicated the sUbjects' basic belief and was identified in the story narrations. The findings were significant to health care in terms of education, increased dignity for the elderly and better understanding by society. The profiles represented an average age of 86.3 years with age showing no bearing on the life experiences associated with the emerging themes. Overwhelmingly, belief was shown to be the foundation in reminiscing. A Judeo-Christian cultural value base supported the belief in 90% of the sUbjects; however, different beliefs were clearly shown indicating that belief is central to all thinking beings, in everyday life and in reminiscing. Belief was not necessarily spiritual or a practised or verbalized religion. It was shown to be a way of understanding, a fundamental and single thread tying the individual's life and stories together. The benefits were the outcomes, in that knowledge of an individual's belief can optimize care planning for any age group, and/or setting. The strength of the study was the open question format and the feedback process of data verification. The unrestricted outcomes and non-specificity were significant in a world where dying is everybody's business.

Understanding space, place and leisure of women over 85 living in the community

There is an increase in the number of older adults 85 and over, who are choosing to live alone within the community. Moreover, older adults who live alone are reportedly spending an extensive amount of time alone within the home environment. In an effort to provide additional support and resources to older adults living in the community, a compliment of services are being offered through public and private organizations. These in-home supports focus on the instrumental or functional tasks of daily living, such as personal and rehabilitative care, nourishment, maintenance and upkeep of the home, as well as volunteer social visitation. However leisure resources and programs are not included among these services. Consequently, this creates a gap in leisure provision among this segment of the population. Throughout the life course, an individual's identity, role and purpose are developed and sustained through instrumental work roles in the formal and informal sector, as well as through personally meaningful leisure pastimes and experiences. Although roles shift post retirement, participation in instrumental and expressive activities can provide opportunities through which older adults are able to fulfill their need for agency (individuality and autonomy) and affiliation (social relatedness). Therefore barriers that inhibit instrumental or leisure experiences can negatively impact older adults' quality of life. This study explored the leisure lifestyles of four older adults, all of whom were over 85, lived alone within the community and were oriented to person, time and place. It became apparent that participants ordered their lives around a routine that consisted of instrumental, expressive and socially integrated tasks and activities. Moreover participants purposely chose to remain at home because their home environment facilitated freedom, choice and independence. As a result all four participants viewed their independence within the home as a critical determinant to their overall quality of life. Challenges associated with the home environment, participants' personal capacities and relationships were negotiated on a daily basis. Failure to positively adapt to these challenges inhibited meaningful engagement and personal fulfillment. Traditionally, leisure service delivery has been offered within institutions and through various community based venues. As a result leisure provision has been focused on the needs of the frail elderly who reside in institutions or the well elderly who are able to access leisure amenities within the community. However the growing number of older adults electing to live alone is on the rise. As individuals age the home becomes the preferred context for leisure experiences. If older adults are choosing to live alone, then both their instrumental and leisure needs must be addressed. As a result, it is imperative that leisure professionals extend the scope of service delivery to include home centered older adults.

Exploration de la perception de l’interdisciplinarité de la part des infirmières en milieu gériatrique

Problématique : Dans un contexte de vieillissement de la population et de complexification des besoins de santé, travailler en interdisciplinarité est devenu une nécessité pour prodiguer des soins de qualité aux personnes âgées vulnérables. Les avantages de l’interdisciplinarité sont connus mais son intégration dans la pratique des professionnels de la santé se vit parfois difficilement. La compréhension de la perception de l’interdisciplinarité de la part des infirmières est un élément majeur d’une pratique de collaboration interprofessionnelle réussie, mais ce sujet a été peu étudié, encore moins en milieu gériatrique. Méthodologie : Le but de cette étude était d’explorer la perception de l’interdisciplinarité des infirmières dans le cadre d’une étude qualitative exploratoire. Les données ont été collectées grâce à sept entrevues semi-dirigées et une discussion de groupe. La méthode de Tesch (1990) fut utilisée pour l’analyse des données et une représentation de la perception fut élaborée. Résultats : Pour les participantes, l’interdisciplinarité est perçue comme un processus d’équilibre parfois difficile entre leur désir d’affirmer leur identité professionnelle et leur désir de collaborer et de travailler en synergie avec les autres intervenants, et ce pour le bien-être de la personne âgée. Elles trouvent que l’apport de l’infirmière à l’équipe interdisciplinaire est indispensable et que sa disponibilité et sa proximité du patient lui donne un statut privilégié pour être le pivot au sein de l’équipe interdisciplinaire. Elles soulignent aussi que la vulnérabilité de la clientèle et l’absence du proche-aidant lors des réunions interdisciplinaires poussent les infirmières à jouer le rôle de porte-parole de la personne âgée. Elles identifient unanimement la communication comme l’élément déterminant d’une collaboration réussie. Elles ajoutent que le leadership, la compétence et l’expérience de l’infirmière sont des déterminants importants pour une interdisciplinarité réussie, alors que la présence du désir de collaborer et le respect mutuel doivent être présents chez tous les intervenants de l’équipe pour collaborer harmonieusement. Par ailleurs, parmi tous les facteurs structurels et organisationnels, seule la pénurie des ressources professionnelles a été identifiée comme un déterminant ayant une incidence sur le travail interdisciplinaire.

L’expérience de l’isolement de contact à l’hôpital pour des personnes âgées lors d’une infection au Clostridium difficile

Sommaire La situation actuelle des infections nosocomiales dans les établissements de santé est préoccupante. En ce qui concerne le Clostridium difficile (C. difficile), son émergence et son impact sur la morbidité et la mortalité sont bien connus. De plus, la population vieillissante est à risque élevé d’avoir des diarrhées associées au C. difficile et, de ce fait, de se retrouver en isolement de contact. Les personnes âgées sont déjà vulnérables au moment d’une hospitalisation, alors qu’en est-il lors d’un isolement de contact relié à une infection au C. difficile? Dans cette perspective, les connaissances sur l’expérience des personnes âgées lors d’un isolement étant peu développées, cette étude s’est intéressée au vécu des personnes âgées durant l’isolement de contact et aux effets de cet isolement sur leur vécu. Le but de cette étude phénoménologique, prenant appui sur la Théorie de l’humain en devenir de Parse (2003), était de décrire et comprendre l’expérience de personnes âgées de 75 ans et plus lors d’un isolement de contact en milieu hospitalier causé par une infection au C. difficile. Ainsi, des entrevues semi-structurées furent réalisées auprès de cinq personnes âgées qui ont accepté de participer à l’étude, puis la transcription de leurs propos fut analysée selon la méthode proposée par Giorgi (1997). De cette analyse sont ressortis trois thèmes : 1) Vivre les effets du Clostridium difficile; 2) Vivre de l’inquiétude et 3) Vivre de la déception dans la relation avec le personnel soignant. Poussant plus loin l’analyse des thèmes et sous-thèmes, il a été possible de proposer que l’essence de l’expérience de personnes âgées de 75 ans et plus lors d’un isolement de contact en milieu hospitalier causé par une infection au C. difficile était de « vivre à la fois en conjonction avec le besoin d’être isolé pour protéger son univers et en séparation avec le besoin de recevoir des soins qui respectent leur dignité, et ce, malgré la vulnérabilité induite par leur état de santé ». Ces résultats pourront sensibiliser les personnes soignantes qui accompagnent au quotidien les personnes âgées en isolement. La compréhension de leur vécu pourra favoriser la mise en place de soins davantage centrés sur la personne qui tiennent compte de leurs inquiétudes, de leurs craintes et de l’importance de préserver leur dignité. Mots clés : Effets psychologiques, expérience de l’isolement de contact, Clostridium difficile, personnes âgées, phénoménologie, théorie de l’humain en devenir.

Conditions de vie des personnes âgées en Afrique Subsaharienne : cas de la vie dans un ménage à génération coupée au Niger

Comme dans la plupart des pays francophones d’Afrique Subsaharienne, la question du vieillissement ou la situation des personnes âgées ne sont pas encore d’actualité au Niger, principalement à cause de la jeunesse de sa population d’une part et d’un intérêt plus porté sur les enfants, les adolescents et les mères d’autre part. Pourtant le Niger fait face à une crise économique sans précédent qui peut avoir des conséquences néfastes sur les conditions de vie des personnes âgées. D’un côté, selon la coutume, la personne âgée (généralement grand parent) s’occupe principalement des petits enfants (orphelins ou non) qui lui sont confiés par leurs parents vivant dans la même localité ou ailleurs, ou qui sont décédés. De l’autre, l’absence d’un jeune adulte dans un ménage où vit au moins une personne âgée est considérée comme un phénomène social préoccupant dans les pays à forte prévalence de VIH/SIDA. Le Niger fait partie des pays où la proportion des personnes âgées vivant avec des petits enfants en l’absence de leurs parents adultes est la plus élevée. Cependant, malgré une forte mortalité adulte, l’absence de données fiables ne permet pas de le classer parmi les pays à forte mortalité adulte due au VIH/SIDA. La raison de cette situation est donc à chercher dans les différences individuelles et communautaires. Jusqu’au début des années 1990, la plupart des études sur les personnes âgées réalisées en Afrique Subsaharienne étaient basées sur les études qualitatives, tandis que les plus récentes sont faites à partir des données des recensements ou enquêtes sociodémoraphiques et économiques. Les conditions de vie des personnes âgées et les conséquences de la pauvreté et du VIH/SIDA sur celles-ci sont les principaux thèmes jusque-là couverts à l’aide des données existantes. Mais, il manque encore de données longitudinales essentielles à l’analyse de certains aspects du cycle de vie des personnes âgées. L’étude n’étant pas sociologique, c’est à l’aide de données démographiques quantitatives, plus précisément le recensement général de la population, que nous tenterons d’expliquer le phénomène sur une base exploratoire. L’analyse au niveau individuel a été faite à l’aide de la régression logistique sous STATA, tandis qu’au niveau contextuel, nous avons utilisé l’analyse multiniveau à l’aide du logiciel HLM (version 6.0). Les résultats indiquent que la vie en l’absence d’un jeune adulte et dans un ménage à génération coupée dépendent principalement du statut sociodémographique de la personne âgée au Niger. Par exemple, il ressort que le mariage avantage l’homme âgé, tandis que le veuvage l’isole plus que la femme âgée. Au niveau contextuel, ce sont les facteurs socioéconomiques qui influencent les conditions de vie des personnes âgées. L’étude montre, en effet, que le degré d’urbanisation d’une commune augmente le risque d’isolement d’une personne âgée qui y réside, alors que le niveau de pauvreté le réduit. Toutefois, nos résultats sont à prendre avec prudence parce qu’en premier lieu il n’existe pas d’études références sur le sujet tant au Niger que dans la sous-région d’Afrique francophone sahélienne. Ensuite, parce que le phénomène étudié pourrait être mesuré de plusieurs manières en fonction du contexte et des données disponibles, et que l’analyse approfondie des effets du statut matrimonial nécessiterait une plus grande connaissance du phénomène chez les personnes âgées. Enfin, compte tenu de la faible prévalence du VIH/SIDA au Niger, les principaux facteurs explicatifs de la vie dans un ménage à génération coupée (aussi bien pour les personnes âgées que pour les enfants) pourraient être le confiage des enfants ou la mortalité adulte due aux autres causes telles que le paludisme, la tuberculose et les maladies infectieuses. Toutefois, l’absence d’informations relatives à ces aspects dans les données utilisées n’a pas permis de les intégrer dans notre étude. Ainsi, compte tenu de la difficulté d’appréhender les contours du phénomène, les futurs programmes en faveur des personnes âgées au Niger et en Afrique Subsaharienne francophone doivent se baser sur des études concrètes relatives aux dimensions sociale et économique du phénomène. Mots clés : Niger - personnes âgées - conditions de vie - mode de vie - cohabitation intergénérationnelle - études comparatives - absence d’un jeune adulte - ménage à génération coupée - Afrique.

Les personnes âgées face au défi d'utilisation des nouvelles technologies : étude de l’utilisabilité des interfaces de téléphones portables

L’évolution technologique et l'accroissement de la population vieillissante sont deux tendances majeures de la dernière décennie. Durant cette période, la prolifération ubiquitaire de la téléphonie mobile a changé les habitudes de communication des gens. Le changement constant des appareils téléphoniques portatifs, l'augmentation des fonctions, la diversité iconographique, la variété des interfaces et la complexité de navigation exigent aujourd’hui non seulement plus de temps d'adaptation et d’apprentissage, mais représentent aussi un effort cognitif important. Les technologies d'information et de communication (TIC) sont devenues des outils incontournables de la vie moderne. Pour les personnes âgées, cet univers en perpétuelle mutation avec ces nouveaux appareils représente un obstacle à l’accès à l’information et contribue ainsi au gap générationnel. Le manque de référence et de soutien et les déficiences physiques ou cognitives, que certaines personnes développent en vieillissant, rendent l'usage de ce type d’objet souvent impossible. Pourtant, les produits intelligents plus accessibles, tant au niveau physique que cognitif sont une réelle nécessité au sein de notre société moderne permettant aux personnes âgées de vivre de manière plus autonome et « connectée ». Cette recherche a pour but d'exposer les défis d'usage des téléphones portables existants et d'identifier en particulier les problèmes d’usage que les personnes âgées manifestent. L’étude vise la tranche de population qui est peu habituée aux technologies de communications qui ne ciblent le plus souvent que les plus jeunes et les professionnels. C’est en regardant les habitudes d’usage, que la recherche qualitative nous permettra d’établir un profil des personnes âgées par rapport au TIC et de mieux comprendre les défis liés à la perception, compréhension et l’usage des interfaces de téléphones portables.
