Protein may play a beneficial role in the prevention of bone loss and in slowing down osteoporosis. The effect of dietary protein may be different in older adults compared to younger adults, since this population has a greater need for protein. The aim of this systematic review and meta-analysis was to investigate the impact of a dietary protein intake above the Recommended Dietary Allowance (RDA) of 0.8 g/kg body weight/day from any source on Bone Mineral Density (BMD)/Bone Mineral Content (BMC), bone turnover markers, and fracture risk in older adults compared to a lower dietary protein ...

Preventing declines in cerebral blood flow is important for maintaining optimal brain health with aging. We compared the effects of a morning bout of moderate-intensity exercise, with and without subsequent light-intensity walking breaks from sitting, on cerebral blood velocity over 8 h in older adults. In a randomized crossover trial, overweight/obese older adults (n = 12, 70 ± 7 yr; 30.4 ± 4.3 kg/m2), completed three acute conditions (6-day washout); SIT: prolonged sitting (8 h, control); EX+SIT: sitting (1 h), moderate-intensity walking (30 min), followed by uninterrupted sitting (6.5 h); and EX + BR: sitting (1 h), moderate-intensity ...

(1) Background: Findings from observational studies of relations between neighborhood environments and health outcomes underscore the importance of both objective and perceived experiences of those environments. A clearer understanding of the factors associated with discrepancies between these two assessment approaches is needed to tailor public health interventions to specific populations. This study examined how individual and neighborhood characteristics affect perceptions of supermarket distance, particularly when perceptions do not match objective measures. (2) Methods: Participants were older adults (n = 880) participating in the Senior Neighborhood Quality of Life Study in the Seattle/King County, WA or Baltimore/Washington, DC regions. Two ...

Malnutrition is very prevalent in geriatric patients with hip fracture. Nevertheless, its importance is not fully recognized. The objective of this paper is to review the impact of malnutrition and of nutritional treatment upon outcomes and mortality in older people with hip fracture. We searched the PubMed database for studies evaluating nutritional aspects in people aged 70 years and over with hip fracture. The total number of studies included in the review was 44, which analyzed 26,281 subjects (73.5% women, 83.6 ± 7.2 years old). Older people with hip fracture presented an inadequate nutrient intake for their ...

Background Recruitment of participants into long-term community-based lifestyle intervention trials, particularly adults with a chronic disease, is often slow and challenging. Currently there is limited data on successful recruitment strategies suitable for older adults with type 2 diabetes into community-based exercise and nutrition programs, and no information on cost estimates associated with such recruitment. The aim of this report is to describe the recruitment strategies used and the success of each approach in recruiting older adults with type 2 diabetes into a 6-month community-based exercise and nutritional supplementation randomised controlled trial (RCT). A secondary aim is to assess the costs ...

Background: Direct relationships between safety concerns and physical activity have been inconsistently patterned in the literature. To tease out these relationships, crime, pedestrian, and traffic safety were examined as moderators of built environment associations with physical activity. Methods: Exploratory analyses used two cross-sectional studies of 2068 adults ages 20–65 and 718 seniors ages 66+ with similar designs and measures. The studies were conducted in the Baltimore, Maryland-Washington, DC and Seattle-King County, Washington regions during 2001–2005 (adults) and 2005–2008 (seniors). Participants were recruited from areas selected to sample high- and low- income and walkability. Independent variables perceived crime ...

Faculty of Health Sciences Publications

Background: The Engaging with older adults in the development of strategies for the self management of chronic pain (EOPIC) study aims to design and develop self management strategies to enable older adults to manage their own pain. Involving older adults in research into chronic pain management will better enable the identification and development of strategies that are more appropriate for their use, but how can perspectives really be utilised to the best possible outcomes? Method: Seven older adults were recruited through a local advertising campaign to take part. We also invited participants from the local pain services, individuals who had ...

Get Your Life Back': Process And Impact Evaluation Of An Asthma Social Marketing Campaign Targeting Older Adults, Uwana Evers, Sandra C. Jones, Don Iverson, Peter Caputi

Faculty of Health Sciences Publications

Background: Asthma in older adults is underdiagnosed and poorly self-managed. This population has little knowledge about the key symptoms, the prevalence among older adults, and the serious consequences of untreated asthma. The purpose of this study was to undertake a multifaceted evaluation of a social marketing campaign to increase asthma awareness among older adults in a regional Australian community. Methods: A cohort of older adults in an intervention region ( n = 316 ) and a control region ( n = 394 ) were surveyed immediately prior to and following the social marketing campaign. Campaign awareness, message recall, materials recognition, and actions taken as a result ...

Access To Commercial Destinations Within The Neighbourhood And Walking Among Australian Older Adults, Andrea Grace Nathan, Gavin Pereira, Sarah Foster, Paula Hooper, Dick Saarloos, Billie Giles-Corti

Faculty of Health Sciences Publications

Background Physical activity, particularly walking, is greatly beneficial to health; yet a sizeable proportion of older adults are insufficiently active. The importance of built environment attributes for walking is known, but few studies of older adults have examined neighbourhood destinations and none have investigated access to specific, objectively-measured commercial destinations and walking. Methods We undertook a secondary analysis of data from the Western Australian state government’s health surveillance survey for those aged 65–84 years and living in the Perth metropolitan region from 2003–2009 (n = 2,918). Individual-level road network service areas were generated at 400 m and ...


Using Gps Technology To (Re)-Examine Operational Definitions Of 'Neighbourhood' In Place-Based Health Research, Bryan Boruff, Andrea Grace Nathan, Sandra Nijënstein Jan 2012

Using Gps Technology To (Re)-Examine Operational Definitions Of 'Neighbourhood' In Place-Based Health Research, Bryan Boruff, Andrea Grace Nathan, Sandra Nijënstein

Faculty of Health Sciences Publications

Background Inconsistencies in research findings on the impact of the built environment on walking across the life course may be methodologically driven. Commonly used methods to define ‘neighbourhood’, from which built environment variables are measured, may not accurately represent the spatial extent to which the behaviour in question occurs. This paper aims to provide new methods for spatially defining ‘neighbourhood’ based on how people use their surrounding environment. Results Informed by Global Positioning Systems (GPS) tracking data, several alternative neighbourhood delineation techniques were examined (i.e., variable width, convex hull and standard deviation buffers). Compared with traditionally used buffers (i ...


"I Feel So Stupid Because I Can't Give A Proper Answer…" How Older Adults Describe Chronic Pain: A Qualitative Study, Amanda Clarke, Geraldine Anthony, Denise Gray, Derek Jones, Paul Mcnamee, Pat Schofield, Blair H. Smith, Denis Martin Jan 2012

"I Feel So Stupid Because I Can't Give A Proper Answer…" How Older Adults Describe Chronic Pain: A Qualitative Study, Amanda Clarke, Geraldine Anthony, Denise Gray, Derek Jones, Paul Mcnamee, Pat Schofield, Blair H. Smith, Denis Martin

Faculty of Health Sciences Publications

Background: Over 50% of older adults experience chronic pain. Poorly managed pain threatens independent functioning, limits social activities and detrimentally affects emotional wellbeing. Yet, chronic pain is not fully understood from older adults’ perspectives; subsequently, pain management in later life is not necessarily based on their priorities or needs. This paper reports a qualitative exploration of older adults’ accounts of living with chronic pain, focusing on how they describe pain, with a view to informing approaches to its assessment. Methods: Cognitively intact men and women aged over sixty-five who lived in the community opted into the study through responding to ...
