Socio-economic inequalities in mortality persist into old age in New Zealand : study of all 65 years plus, 2001-04

A number of studies have explored the relationship between socioeconomic status (SES) and mortality, although these have mostly been based on the working age population, despite the fact that the burden of mortality is highest in older people. Using Poisson regression on linked New Zealand census and mortality data (2001 to 2004, 1.3 million person years) with a comprehensive set of socioeconomic indicators (education, income, car access, housing tenure, neighourhood deprivation) we examined the association of socioeconomic characteristics and older adult mortality (65+ years) in New Zealand. We found that socioeconomic mortality gradients persist into old age. Substantial relative risks of mortality were observed for all socioeconomic factors, except housing tenure. Most relative risk associations decreased in strength with aging (e.g. most deprived compared to least deprived rate ratio for males reducing from 1.40 (95% CI 1.28 to 1.53) for 65-74 year olds to 1.13 (1.00 to 1.28) for 85+ year olds), except for income and education among women where the rate ratios changed little with increasing age. This suggests individual level measures of SES are more closely related to mortality in older women than older men. Comparing across genders, the only statistically significantly different association between men and women was for a weaker association for women for car access.

Cognitive-reminiscence therapy and usual care for depression in young adults: study protocol for a randomized controlled trial

Background
Depression is a common affliction for young adults, and is associated with a range of adverse outcomes. Cognitive-reminiscence therapy is a brief, structured intervention that has been shown to be highly effective for reducing depressive symptoms, yet to date has not been evaluated in young adult populations. Given its basis in theory-guided reminiscence-based therapy, and incorporation of effective therapeutic techniques drawn from cognitive therapy and problem-solving frameworks, it is hypothesized to be effective in treating depression in this age group.

Methods and design
This article presents the design of a randomized controlled trial implemented in a community-based youth mental health service to compare cognitive-reminiscence therapy with usual care for the treatment of depressive symptoms in young adults. Participants in the cognitive-reminiscence group will receive six sessions of weekly, individual psychotherapy, whilst participants in the usual-care group will receive support from the youth mental health service according to usual procedures. A between-within repeated-measures design will be used to evaluate changes in self-reported outcome measures of depressive symptoms, psychological wellbeing and anxiety across baseline, three weeks into the intervention, post-intervention, one month post-intervention and three months post-intervention. Interviews will also be conducted with participants from the cognitive-reminiscence group to collect information about their experience receiving the intervention, and the process underlying any changes that occur.

Discussion
This study will determine whether a therapeutic approach to depression that has been shown to be effective in older adult populations is also effective for young adults. The expected outcome of this study is the validation of a brief, evidence-based, manualized treatment for young adults with depressive symptoms.

Violent offending, masculinity and age: exploring the role of developmental processes in adulthood

While the link between violent crime and masculinity is often implicitly assumed, to date, research has not specifically investigated beliefs about violence and masculinity at different stages of the adult life-course. This thesis explored the role of maturational processes in the way beliefs about masculinity and violence may differ in early and middle adulthood. Results of a quantitative study did not uncover statistically significant differences between younger and older adult violent offenders on a measure of criminal thinking. However, results of an interpretative phenomenological analysis indicated that beliefs about masculinity may differentially influence violent crime at different stages of adulthood. The results of these two studies provide a foundation for arguing that beliefs about violence and masculinity change throughout the life-course, and that masculinity in particular may be important treatment target in contemporary rehabilitation programs.

Prior fracture as a risk factor for future fracture in an Australian cohort

This study investigated the influence of prior fracture on the risk of subsequent fracture. There was a higher risk of subsequent fracture in both young and older adult age groups when Australian males or females had already sustained a prior fracture. Fracture prevention is important throughout life for both sexes.

A case study illustrating therapist-assisted internet cognitive behavior therapy for depression

Randomized controlled trials show that therapist-assisted Internet cognitive behavior therapy (ICBT) is efficacious in the treatment of depression. Given that this is a novel way of delivering cognitive behavior therapy, however, clinical service providers may have questions about how to provide therapist-assisted ICBT in clinical practice, particularly with respect to therapist assistance. To exemplify this approach, we present a case study of an older adult male who received 12 modules of therapist-assisted ICBT for depression over the course of 5. months. Highlights of the therapeutic exchanges that occurred over email are provided to illustrate the type of information clients may share with therapists and the nature of therapist assistance. Treatment progress was assessed via self-report questionnaires measuring depression, anxiety, and adjustment. Consistent with the research evidence, significant improvement was observed on all symptom measures at posttreatment. Satisfaction with the therapist-assisted ICBT program and a strong therapeutic alliance was also reported. The case will expand clinician understanding of therapist-assisted ICBT and may serve to stimulate clinician interest in the provision of therapist-assisted ICBT. Future research directions stemming from this case are presented. © 2013 .

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

Stretching Exercise Program Improves Gait in the Elderly

Background: Ageing is characterized by a number of physical changes that contribute to a decline in the ability to perform daily tasks. Stretching has been proposed to reduce hip flexion contracture and increase hip and pelvis range of motion, thus improving gait performance. Objective: The purpose of this study was to determine whether a supervised stretching program designed to improve the range of motion of the lower limbs alters gait kinematics in older adults. Methods: Twenty healthy older adult women (65.9 +/- 4.2 years old and BMI 24.9 +/- 3.5) were divided into 2 groups. The experimental group undertook 12 sessions of stretching exercises, whereas the control group did not engage in any physical activity. Gait performance was assessed at the beginning of the experiment and after the 4-week intervention period. Results: Those in the experimental group showed increased step length, higher velocity and reduced double support time after training. In addition, participants involved in the stretching program showed greater anterior and lateral pelvis tilt and also greater rotation (p < 0.05). Conclusions: Based on our results, we can suggest that a supervised stretching program is effective to alter a number of gait variables. Moreover, after the stretching protocol, aged participants displayed gait parameters which were similar to those reported in young healthy adults. Therefore, stretching can be used as an effective means to improve range of motion and reverse some age-related changes that influence gait performance. Copyright (C) 2009 S. Karger AG, Basel

Variabilidade de parâmetros eletromiográficos e cinemáticos em diferentes condições de marcha em idosos

The main goal of this study was to investigate the influence of fear of fall and dual task on electromyographic and kinematic variability parameters on the gait of older females. Seventeen college students (21,47 ± 2,06 years old) and eighteen older female adults, both groups were physically fit and performed the gait test on three different conditions: walking at self-select speed, fear of fall and dual task. Electromyographic activity was measured on muscles of dominant leg and stride time was recorded. ANOVA two-way (p<0.05) was used. Electromyographic and kinematic gait variability were higher in older adult groups. However, for the comparison between gait conditions was only found significant difference for electromyographic variability. In line with this, the higher EMG and kinematic variability in older adults suggest that aging contributes for a higher motor challenge while walking, which may be predispose these individuals a higher risk of fall.

Longevidad y cambios en la periodicidad de la vida adulta : Nuevos paradigmas de una vejez emergente

La longevidad y la prolongación del envejecimiento, constituyen una fuente de confusión e incertidumbre entre personas, organizaciones y comunidades. Surgen paradigmas en oposición, con perspectivas positivas y negativas del envejecimiento, que no ayudan a la comprensión de las nuevas dimensiones de este período del ciclo vital. En el presente trabajo se enfatiza la necesidad de definir de manera clara las etapas intermedias en el interior de la vida del adulto mayor, analizar con este foco los paradigmas contrapuestos y superar la lógica binaria existente -con un análisis dialógico- de modo de rescatar algunos de los principios emergentes sobre la creciente longevidad

Entornos de ayuda a la vida independiente de personas mayores sobre servicios de redes de próxima generación

El progresivo envejecimiento de la población está produciendo una elevada demanda de servicios socio‐asistenciales por parte de las personas mayores para mantener su vida independiente y el consiguiente “envejecimiento activo”. La iniciativa Ambient Assisted Living (AAL) promueve el “envejecimiento activo” a través de las Tecnologías de la Información y las Comunicaciones (TIC) y es en ella donde se centrará el trabajo de esta tesis doctoral. Una característica fundamental de los servicios AAL es su adaptación y personalización a las características y preferencias del usuario y su contexto. Así, el paradigma “context awareness” presenta una gran relevancia en la provisión de servicios AAL y en el soporte a la vida independiente de las personas mayores. Concretamente, la utilización de ontologías permite crear modelos de usuarios y contexto que pueden ser utilizadas para los mecanismos de razonamiento incluidos en los servicios context‐aware. Por otra parte, los usuarios actualmente precisan acceder a un conjunto de servicios desde cualquier red de acceso y desde cualquier dispositivo. Las redes de próxima generación (Next Generation Networks‐NGN) lo hacen posible pues ofrecen una convergencia dispositivo‐red‐servicio. La tecnología IMS (IP Multimedia Subsystem) es una arquitectura que implementa el paradigma NGN y ofrece una serie de servicios de red genéricos llamados servicios habilitadores o enablers que pueden ser reutilizados en cualquier aplicación, soportando mecanismos de interoperabilidad entre aplicaciones y permitiendo un desarrollo robusto, rápido y sencillo. Además, los servicios enablers permiten mecanismos de gestión de la información de usuario para realizar una provisión adaptada del servicio en función de la información del estado del usuario. El objetivo de esta tesis doctoral se centra en establecer un marco de convergencia entre estos dos campos diseñando y desarrollando un conjunto de servicios enablers soportados en una arquitectura IMS implementada para soportar la provisión de aplicaciones AAL bajo el paradigma context‐awareness y la triple convergencia reddispositivo‐ servicio cubriendo así las necesidades y requisitos de las personas mayores. Entre las aportaciones de la presente tesis se destaca la realización de un modelo de plataforma servicios AAL, denominado Residencia Virtual Asistiva, para su provisión en el domicilio de la persona mayor, así como la propuesta de implementación de sus servicios a través de servicios enablers. Por otra parte se define una ontología destinada a modelar servicios AAL así como sus usuarios (personas mayores) para lograr una provisión personalizada y adaptada de servicios AAL. Esta ontología se ha implementado a través del servicio de presencia de la arquitectura IMS para poder crear perfiles de usuario y así poder realizar dicha provisión personalizada. Además, se desarrolla una aplicación de teleconsulta, como ejemplo de servicio AAL, que utiliza una serie de servicios enablers desarrollados para ofrecer funcionalidades avanzadas a la aplicación. Bajo el paradigma contex‐awareness se ha desarrollado y evaluado técnicamente un servicio enabler para ofrecer soporte a la movilidad y a la independencia de las personas mayores con deterioro cognitivo que sufren episodios de desorientación espacial. ABSTRACT The progressive ageing of the population is making elderly people demand sociohealthcare services to maintain an independent living and therefore an “active ageing”. The initiative Ambient Assisted Living (AAL), on which the current PhD thesis is focused, promotes the “active ageing” by means of Information and Communication Technologies (ICT). Essential features of AAL services are the adaptation and personalization to the user’s characteristics and preferences as well as user’s context. Thus, the “context‐awareness” paradigm implies a great importance in the AAL service provision and the elderly independent living support. In particular, the usage of ontologies allows creating user and contexts models to be employed in the reasoning mechanism of context‐aware services. On the other hand, users currently require accessing to a set of services from anywhere and any device. Next‐Generation Networks (NGN) support this need by offering a service‐network‐device convergence. The IP Multimedia Subsystem (IMS) technology is an architecture that implements the NGN paradigm and offers a generic network services know as service enabler which can be reused by any application supporting application interoperability mechanism as well as allowing a simple, fast and robust application development. Furthermore, the service enablers offer user’s information management procedures to achieve and adapt service provision considering the user’s status. The objective of this PhD thesis is focused on establishing a convergence framework between these two previous fields by designing and developing a group of service enablers that will be deployed in an IMS architecture. The enablers developed will support the AAL applications provision from the context‐awareness paradigm and service‐network‐device convergence in order to cover the elderly people’s requirements and needs. Among the contributions achieved in this PhD thesis, the definition of an AAL platform service model, named as “Assited Virtual Nursing Home”, for being deployed in the older adult home is emphasised. In addition, a proposal of service enablers to support the AAL service defined in the model is made. Otherwise, an ontology is defined to model AAL services as well as their users with the aim at achieve a personalized and adapted AAL service. This ontology has been implemented by means of the IMS service presence in order to create users profiles to be used in the personalized AAL services. As an example of AAL service, a teleconsulting application has been developed to employ a group of service enablers developed using a set of advanced functionalities. Considering the context‐paradigm, a service enabler has been developed and technologically evaluated to support the mobility and independence of elderly people with mild cognitive impairment who suffers spatial disorientation episodes.

Mobility and Aging in Denver, Colorado: Travel Behavior, Mobility Barriers, and Perceptions of Transit

The number of seniors in the U.S. today is growing rapidly because of longer life expectancies and the aging Baby Boomer generation. This age groups' travel behavior will have substantial impacts on transportation, economics, safety, and the environment. This research used a mixed-methods approach to address issues of mobility and aging in Denver, Colorado. A quantitative approach was used to answer broad questions about travel behavior and the effects of age, gender, work status, disability, residential location and socio-economic status on mobility. Qualitative interviews with seniors in the Denver metro area were conducted to identify barriers to mobility, decision-making processes and travel decisions, and seniors' perceptions of public transit. The results of the quantitative and qualitative analyses show that residential location is an important variable for determining seniors' travel behaviors and transportation options. Perceptions of public transit were positive, but accessibility and information barriers exist that prevent older adult from using transit. The findings of this study will help to provide transportation and service recommendations to policymakers and planners in the Denver area as well as to inform studies of other North American cities with large aging populations.
