Building capacity for ageing and disability-related research

Since 1997, EQUAL has supported over forty ageing and disability-related research projects, many of which demonstrating an inclusive design dimension. Some of these projects have had a significant influence on policy and practice. However, less progress has been made in promoting ageing-related research in scientific areas. Building on the experience gained in developing the inclusive design research community, SPARC was created with the aim to provide opportunities for introducing newcomers across a wide range of engineering and biological fields to ageing and disability-related research. Through an awards scheme, SPARC provides financial support, mentoring, editorial assistance and a platform for dissemination and access to international activities. In addition, SPARC organises national and international workshops that showcase the latest research and educates individuals, society and government about the value of ageing and disability-related research.

Diet, ageing and genetic factors in the pathogenesis of diverticular disease

Diverticular disease (DD) is an age-related disorder of the large bowel which may affect half of the population over the age of 65 in the UK. This high prevalence ranks it as one of the most common bowel disorders in western nations. The majority of patients remain asymptomatic but there are associated life-threatening co-morbidities, which, given the large numbers of people with DD, translates into a considerable number of deaths per annum. Despite this public health burden, relatively little seems to be known about either the mechanisms of development or causality. In the 1970s, a model of DD formulated the concept that diverticula occur as a consequence of pressureinduced damage to the colon wall amongst those with a low intake of dietary fiber. In this review, we have examined the evidence regarding the influence of ageing, diet, inflammation and genetics on DD development. We argue that the evidence supporting the barotrauma hypothesis is largely anecdotal. We have also identified several gaps in the knowledge base which need to be filled before we can complete

Chemical ageing and transformation of diffusivity in semi-solid multi-component organic aerosol particles

Recent experimental evidence underlines the importance of reduced diffusivity in amorphous semi-solid or glassy atmospheric aerosols. This paper investigates the impact of diffusivity on the ageing of multi-component reactive organic particles representative of atmospheric cooking aerosols. We apply and extend the recently developed KM-SUB model in a study of a 12-component mixture containing oleic and palmitoleic acids. We demonstrate that changes in the diffusivity may explain the evolution of chemical loss rates in ageing semi-solid particles, and we resolve surface and bulk processes under transient reaction conditions considering diffusivities altered by oligomerisation. This new model treatment allows prediction of the ageing of mixed organic multi-component aerosols over atmospherically relevant time scales and conditions. We illustrate the impact of changing diffusivity on the chemical half-life of reactive components in semisolid particles, and we demonstrate how solidification and crust formation at the particle surface can affect the chemical transformation of organic aerosols.

A study of the antioxidant capacity of oak wood used in wine ageing and the correlation with polyphenol composition

The antioxidant capacity of oak wood used in the ageing of wine was studied by four different methods: measurement of scavenging capacity against a given radical (ABTS, DPPH), oxygen radical absorbance capacity (ORAC) and the ferric reducing antioxidant power (FRAP). Although, the four methods tested gave comparable results for the antioxidant capacity measured in oak wood extracts, the ORAC method gave results with some differences from the other methods. Non-toasted oak wood samples displayed more antioxidant power than toasted ones due to differences in the polyphenol compositon. A correlation analysis revealed that ellagitannins were the compounds mainly responsible for the antioxidant capacity of oak wood. Some phenolic acids, mainly gallic acid, also showed a significant correlation with antioxidant capacity.

Ageing and taste

Taste perception has been studied frequently in young and older adult groups. This paper systematically reviews these studies to determine the effect of ageing on taste perception and establish the reported extent of sensory decline. Five databases were searched from 1900 to April 2012. Articles relating to healthy ageing in human subjects were included, reviewed and rated (Downs and Black scoring system). Sixty-nine studies investigated the effect of ageing on taste perception; forty examined detection thresholds of which twenty-three provided sufficient data for meta-analysis, eighteen reported identification thresholds and twenty-five considered supra-threshold intensity perception. Researchers investigating detection thresholds considered between one and thirteen taste compounds per paper. Overall, the consensus was that taste detection thresholds increased with age (Hedges' g = 0·91, P < 0·001), across all taste modalities. Identification thresholds were reported to be higher for older adults in seventeen out of eighteen studies. Sixteen out of twenty-five studies reported perception of taste intensity at supra-threshold levels to be significantly lower for older adults. However, six out of nine studies concerning sucrose found perceived intensity of sweet taste not to diminish with age. The findings of this systematic review suggest taste perception declines during the healthy ageing process, although the extent of decline varies between studies. Overall, the studies reviewed had low Downs and Black scores (mean 16 (SD 2)) highlighting the need for more robust large scale and longitudinal studies monitoring the impact of ageing on the sensory system, and how this influences the perception of foods and beverages.

Värdigt liv och välbefinnande, enligt vem? : en kvalitativ studie om brukare och biståndshandläggares beskrivningar av ett värdigt liv och välbefinnande : Dignity and well-being, according to whom? : a qualitative study of elderly and assistance officer´s descriptions of a dignified life and wellbeing

We are two students named Susanne Grönlund and Anna Zaar and have jointly worked together this c-essay called "dignity and well-being according to whom? The paper is written at Högskolan dalarna in Falun.The purpose of this study was to investigate how the elderly and assistance officer describes dignity and well-being and how it is consistent with the government's bill on the national values that the National Board has developed.Our empirical study consists of four qualitative interviews, two older people dependent on community care and two assistance officers. The study's theoretical basis is Antonovsky's salutogenic approach and SOC. The survey focuses on different themes such as dignity, integrity, participation, treatment, wellbeing, security and meaningfulness which are also central themes in the Government Bill on the national values for elderly.The results show that the respondents believe that a life of dignity is difficult to define and also a subjective experience. The results also show a consistency between what the elderly, assistance officer and the national values that define dignity and well-being. Social Services Act, national values should serve as a starting point for municipalities to improve elderly care, thereby creating a sense of coherence for the individual. Keywords: Elder care, dignity, integrity, participation, attitude, well-being, security and meaningfulness.

'Moving On' and Transitional Bridges : Studies on migration, violence and wellbeing in encounters with Somali-born women and the maternity health care in Sweden

During the latest decade Somali-born women with experiences of long-lasting war followed by migration have increasingly encountered Swedish maternity care, where antenatal care midwives are assigned to ask questions about exposure to violence. The overall aim in this thesis was to gain deeper understanding of Somali-born women’s wellbeing and needs during the parallel transitions of migration to Sweden and childbearing, focusing on maternity healthcare encounters and violence. Data were obtained from medical records (paper I), qualitative interviews with Somali-born women (II, III) and Swedish antenatal care midwives (IV). Descriptive statistics and thematic analysis were used. Compared to pregnancies of Swedish-born women, Somali-born women’s pregnancies demonstrated later booking and less visits to antenatal care, more maternal morbidity but less psychiatric treatment, less medical pain relief during delivery and more emergency caesarean sections and small-for-gestational-age infants (I). Political violence with broken societal structures before migration contributed to up-rootedness, limited healthcare and absent state-based support to women subjected to violence, which reinforced reliance on social networks, own endurance and faith in Somalia (II). After migration, sources of wellbeing were a pragmatic “moving-on” approach including faith and motherhood, combined with social coherence. Lawful rights for women were appreciated but could concurrently risk creating power tensions in partner relationships. Generally, the Somali-born women associated the midwife more with providing medical care than with overall wellbeing or concerns about violence, but new societal resources were parallel incorporated with known resources (III). Midwives strived for woman-centered approaches beyond ethnicity and culture in care encounters, with language, social gaps and divergent views on violence as potential barriers in violence inquiry. Somali-born women’s strength and contentment were highlighted, and ongoing violence seldom encountered according to the midwives experiences (IV). Pragmatism including “moving on” combined with support from family and social networks, indicate capability to cope with violence and migration-related stress. However, this must be balanced against potential unspoken needs at individual level in care encounters.With trustful relationships, optimized interaction and networking with local Somali communities and across professions, the antenatal midwife can have a “bridging-function” in balancing between dual societies and contribute to healthy transitions in the new society.

Using environmental interventions to create sustainable solutions to problems to health and wellbeing

Recent research by Deakin University, in collaboration with Parks Victoria and its Strategic Partners, indicates that contact with nature may promote human health and wellbeing. International research indicates that simply viewing a natural scene or watching wildlife reduces stress and tension, improves concentration, remedies mental fatigue, boosts immunity, and enhances psychological health. This is aside from any physical health benefits flowing from reduced stress, increased exercise and improved air quality when contact with nature involves activities in natural environments. The literature suggests that interacting with nature through gardening or having a companion animal is also beneficial for health, and where these activities involve contact with other humans, might extend benefits beyond the individual to the community, through enhanced social capital. This paper sets out the potential scope of work flowing from the initial research, in terms of target groups, research foci, intervention strategies, and likely benefits, and reports on progress in establishing a program of Australian,based empirical research. It proposes the establishment of alliances between researchers and practitioners in a range of disciplines (including environmental health) to ensure that the links between contact with nature and human health and wellbeing are explored and expressed in ways that are both beneficial and sustainable.

Service provision factors that affect the health and wellbeing of people living in a lower SES environment: the perspective of service providers

Inequalities in health and wellbeing within low socioeconomic (SES)  environments are well documented. Factors inherent to the health care system itself, such as inaccessible, inflexible or inappropriate seroiceprovision, contribute to the poorer health status ofresidents oflow SES areas. This paper explores the issues ofseroice provision in low SES areas, documenting the perceptions of seroice providers about the seroice needs of residents, in order to understand the systemic factors that negatively impact on health and wellbeing. A total of54 health and welfare seroice providers from two adjacent low SES suburbs within regional Victoria were interoiewed using qualitative research methods. Keyfindings indicate that successful navigation of health care seroices by residents within these low SES environments is being impeded by issues ofaccess, a lack ofappropriate early interoention options or measures, and general resident disempowerment. Central to the improvement of seroice provision is the need for seroices to become economically, geographically and culturally accessible. In particular, the importance of community involvement in health planning and health promoting seroices must be reflected in the ethos ofseroice provision.

Population health and wellbeing: identifying priority areas for Victorian children

Background
Population health information, collected using soundly-designed methodologies, is essential to inform policy, research, and intervention programs. This study aimed to derive policy-oriented recommendations for the content of a health and wellbeing population survey of children 0–12 years living in Victoria, Australia.

Results
Qualitative interviews were conducted with 54 academic and policy stakeholders, selected to encompass a wide breadth of expertise in areas of public health and inter-sectoral organisations relevant to child health outcomes, including universities, government and non-government agencies across Victoria. These stakeholders were asked to provide advice on strategic priorities for child health information (data) using a structured interview technique. Their comments were summarised and the major themes were extracted. The priority areas of health and wellbeing recommended for regular collection include obesity and its determinants, pregnancy and breastfeeding, oral health, injury, social and emotional health and wellbeing, family environment, community, health service utilisation, illness, and socioeconomic position. Population policy questions for each area were identified.

Conclusion
In contrast to previous population survey programs nationally and internationally, this study sought to extract contemporary policy-oriented domains for inclusion in a strategic program of child health data collection, using a stakeholder consultation process to identify key domains and policy information needs. The outcomes are a rich and relevant set of recommendations which will now be taken forward into a regular statewide child health survey program.
