Item Successful Aging in Indonesia: The Journey Toward Expectations and Serenity(Taylor and Francis Group, 2025-04-02) Kusumaningrum FM; Dewi FST; Pangastuti HS; Yeung PDevelopment of aging policies and activities needs perspective from older adults to ensure the inclusion of older adults’ values and needs. The purpose of this study is to investigate the perspective on and experience in achieving successful aging from older adults who live in the community in Sleman Regency, Yogyakarta, Indonesia. A qualitative study using a phenomenological approach was employed to obtain the data from 21 community-dwelling older adults aged 60+ years old and to analyze the data using Colaizzi’s method of phenomenological data analysis. The analysis concludes that successful aging is a process of attaining serenity by managing expectations with adjustment, acceptance, and gratitude. The expectations include the autonomy and health, fulfillment of necessities, family attainments and relationship, and harmonious social relationship. Successful aging programs should support older adults’ process in achieving expectations and improve their capacity to adapt and experience serenity as they age.Item Exploring the Nutrition-Related Health of the Ageing Population in Fiji: A Narrative Review.(SAGE Publications, 2024-10-18) Naliva S; Kruger M; Havea P; Wham CFijis' older population aged 55 years and over makes up 14% of the total population and is expected to reach 20% by 2050. This narrative review aimed to examine the health and nutrition status of the aging population of Fiji and sociodemographic determinants. A search strategy was conducted throughout databases, and gray literature from relevant websites was searched. Due to the limited evidence regarding the nutrition, health, and socio-economic factors that impact the aging population in Fiji the inclusion criteria were broad and included both genders (male and female), all publications up until December 2022, all study designs, and gray literature (government/institutional reports, conference proceedings, guidelines, Act, and Policies) . There was no filter for date applied in the search criteria. Studies that did not meet the search criteria were excluded. 20 documents including published articles were included for analysis and result synthesis. Life expectancy at birth for the Fiji population is 68 years. A significant annual increase in mortality rate from endocrine, nutritional, and metabolic diseases has been observed in women aged 75+ but not older men. Women of low-income status are more at risk than men. However, as most investigations aggregate those ≥18 years, there is a lack of information on older adults (≥65 years) health and nutrition status. To improve the health status of older adults, an understanding of the nutritional status of older adults is warranted, especially concerning lifestyle and sociodemographic determinants.Item The Psychosocial Impacts of Co-Designed Healing Gardens Among Aged Care Residents With and Without Dementia in Nigeria(Taylor and Francis Group, LLC., 2024-10-13) Akindejoye F; Ezedinma U; Röhr SHealing gardens are green spaces that support the interaction of humans and elements of nature to improve well-being and quality of life. However, little is known about healing garden use and outcomes in African countries. This study aimed to design a healing garden intervention and measure its impact on psychosocial factors and quality of life of residents and care staff within two residential aged care facilities in Lagos, Nigeria. Each facility's staff completed the psychosocial measurement tools by proxy for participants between ages 60 and 99, with or without dementia, at baseline and three months following interaction with the garden and completed the garden use observational survey to determine the effect on and use of the garden by care staff and residents. Results revealed an improvement in the quality of life and experiences of agitation but no beneficial change in depression among residents with and without dementia. Further, care staff reported a positive benefit of the garden on their work-life experience and the residents' well-being. This study provides the base for future research on assessing the impact of healing gardens on persons living with dementia in Africa.Item Impact of a High Protein Intake on the Plasma Metabolome in Elderly Males: 10 Week Randomized Dietary Intervention(Frontiers Media S.A., 2019-12-06) Durainayagam B; Mitchell CJ; Milan AM; Zeng N; Sharma P; Mitchell SM; Ramzan F; Knowles SO; Sjödin A; Wagner K-H; Roy NC; Fraser K; Cameron-Smith DHigh protein diets may improve the maintenance of skeletal muscle mass in the elderly, although it remains less clear what broader impact such diets have on whole body metabolic regulation in the elderly. Non-targeted polar metabolomics analysis using HILIC HPLC-MS was used to profile the circulating plasma metabolome of elderly men (n = 31; 74.7 ± 4.0 years) who were randomized to consume for 10 weeks a diet designed to achieve either protein (RDA; 0.8·g-1·kg-1) or that doubled this recommend intake (2RDA; 1.6.g.kg-1). A limited number of plasma metabolites (n = 24) were significantly differentially regulated by the diet. These included markers of protein anabolism, which increased by the 2RDA diet, including; urea, creatine, and glutarylcarnitine. Whilst in response to the RDA diet; glutamine, glutamic acid, and proline were increased, relative to the 2RDA diet (p < 0.05). Metaboanalyst identified six major metabolic pathways to be influenced by the quantity of protein intake, most notably the arginine and proline pathways. Doubling of the recommended protein intake in older males over 10 weeks exerted only a limited impact on circulating metabolites, as determined by LC-MS. This metabolomic response was almost entirely due to increased circulating abundances of metabolites potentially indicative of altered protein anabolism, without evidence of impact on pathways for metabolic health. Trial Registration: This trial was registered on 3rd March 2016 at the Australia New Zealand Clinical Trial Registry (www.anzctr.org.au) at ACTRN 12616000310460.Item Vitamin B and One-Carbon Metabolite Profiles Show Divergent Associations with Cardiometabolic Risk Markers but not Cognitive Function in Older New Zealand Adults: A Secondary Analysis of the REACH Study.(Elsevier B.V., 2023-12-07) Gillies NA; Milan AM; Cameron-Smith D; Mumme KD; Conlon CA; von Hurst PR; Haskell-Ramsay CF; Jones B; Roy NC; Coad J; Wall CR; Beck KLBACKGROUND: Vitamin B inadequacies and elevated homocysteine status have been associated with impaired cognitive and cardiometabolic health with aging. There is, however, a scarcity of research investigating integrated profiles of one-carbon (1C) metabolites in this context, including metabolites of interconnected folate, methionine, choline oxidation, and transsulfuration pathways. OBJECTIVES: The study aimed to examine associations between vitamins B and 1C metabolites with cardiometabolic health and cognitive function in healthy older adults, including the interactive effects of Apolipoprotein E-ε4 status. METHODS: Three hundred and thirteen healthy participants (65-74 y, 65% female) were analyzed. Vitamins B were estimated according to dietary intake (4-d food records) and biochemical status (serum folate and vitamin B12). Fasting plasma 1C metabolites were quantified by liquid chromatography with tandem mass spectrometry. Measures of cardiometabolic health included biochemical (lipid panel, blood glucose) and anthropometric markers. Cognitive function was assessed by the Computerized Mental Performance Assessment System (COMPASS) and Montreal Cognitive Assessment (MoCA). Associations were analyzed using multivariate linear (COMPASS, cardiometabolic health) and Poisson (MoCA) regression modeling. RESULTS: Over 90% of participants met dietary recommendations for riboflavin and vitamins B6 and B12, but only 78% of males and 67% of females achieved adequate folate intakes. Higher serum folate and plasma betaine and glycine concentrations were associated with favorable cardiometabolic markers, whereas higher plasma choline and homocysteine concentrations were associated with greater cardiometabolic risk based on body mass index and serum lipids concentration values (P< 0.05). Vitamins B and homocysteine were not associated with cognitive performance in this cohort, though higher glycine concentrations were associated with better global cognitive performance (P = 0.017), episodic memory (P = 0.016), and spatial memory (P = 0.027) scores. Apolipoprotein E-ε4 status did not modify the relationship between vitamins B or 1C metabolites with cognitive function in linear regression analyses. CONCLUSIONS: Vitamin B and 1C metabolite profiles showed divergent associations with cardiometabolic risk markers and limited associations with cognitive performance in this cohort of healthy older adults.Item The Effects of GreenShell Mussel Powder (Brand-Named PERNAULTRA) on Physical Performance and Subjective Pain, Symptoms, and Function Measures in Knee Osteoarthritis: A 6-Mo Randomized, Double-Blind, Placebo-Controlled Trial(Elsevier Inc. on behalf of American Society for Nutrition, 2024-04) Slade CAJ; Kruger MC; Miller MR; Mazahery H; Beck KL; Conlon CA; Von Hurst PRBackground: Osteoarthritis (OA) can cause disability and reduce quality of life (QoL). Objectives: This study aimed to determine whether GreenShell mussel (GSM) powder (PERNAULTRA) consumption was more effective than placebo at improving physical performance and subjective measures of symptoms and function in adults with early signs of knee OA. Methods: The Researching Osteoarthritis and GSM study was a 6-mo randomized, double-blind, placebo-controlled trial in adults aged 55–80 y, screened for signs of OA (n = 120, 65.9 ± 6.43 y, 63% female). Participants consumed either 3 g of powdered whole GSM or placebo (pea protein) daily. Baseline and end data collection included 30-s chair stand, stair test, 40-m fast-paced walk test, Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire categorized into 5 subscales [pain (P), symptoms except pain (S), function in activities of daily living (ADL), function in sports/recreation (SP), and QoL], a measure of Intermittent and Constant Osteoarthritis Pain, and visual analog scale of pain and symptoms. Results: Visual analog scale symptoms showed a significantly greater reduction in percentage change for GSM than that for placebo [−28.1 (−59.2, 43.2) compared with 0.00 (−28.6, 100); P = 0.03]. Further, a trend for improvement in percentage change for GSM compared with placebo was seen in 40m fast-paced walk [2.51 (−3.55, 8.12) compared with 0.20 (−6.58, 4.92); P = 0.09], KOOS-SP [11.4 (−4.48, 27.0) compared with 0.00 (−11.1, 17.7); P = 0.09], and Intermittent and Constant Osteoarthritis Pain intermittent pain scale [−27.7 (−77.3, 0.00) compared with −14.6 (−50.0, 36.4); P = 0.08]. In those with body mass index (BMI; in kg/m2) <25, GSM consumption significantly improved KOOS-S compared with placebo [6.35 (3.49, 12.7) compared with 0.00 (−4.65, 4.49); P = 0.03] and showed a trend for improvement in KOOS-ADL [3.29 (1.01, 8.79) compared with 1.01 (−5.75, 4.30); P = 0.07]. Those with BMI of ≥25, consuming GSM showed a trend for improvement in KOOS-SP [13.6 (−4.76, 33.3) compared with 0.00 (−12.5, 20.0); P = 0.07]. Conclusions: This research suggests consumption of GSM has potential to alleviate symptoms and improve functionality in OA. This trial was registered at Clinical Trial Registry as ACTRN12620001112954p (https://www.anzctr.org.au/ACTRN12620001112954p.aspx).Item Becoming an informal care-giver: The role of work status incongruence(Cambridge University Press, 2022-02-10) Koreshi SY; Alpass FThe ageing of the workforce suggests that many older adults will be combining work and care. While there is extensive evidence for the impact of informal care-giving on paid employment, there is less research on how work status may influence the provision of informal care. It has also yet to be established whether work preferences may influence the uptake of care-giving responsibilities, particularly for older workers. We investigated the impact of work status congruence on taking up informal care at two-year follow-up. A sample of 1,211 employed participants aged 55–70 years was surveyed over two consecutive waves. Involuntary part-time workers were more likely to provide care at Time 1 than involuntary full-timers, voluntary part-timers and voluntary full-timers. Participants were more likely to take up care if the opportunity costs of doing so were low, however, only for those whose preferences for more work were not met. There were no moderating effects of gender and economic living standards on the relationship between work status incongruence and provision of care-giving. Understanding the decision-making processes older workers undertake when taking up informal care are complex and must consider the influence of personal work preferences. These findings have implications for care and work-based policy given the importance of informal care in sustaining ageing-in-place policies.Item Malnutrition Risk: Four Year Outcomes from the Health, Work and Retirement Study 2014 to 2018(MDPI (Basel, Switzerland), 2022-05-26) Wham C; Curnow J; Towers AThis study aimed to determine four-year outcomes of community-living older adults identified at 'nutrition risk' in the 2014 Health, Work and Retirement Study. Nutrition risk was assessed using the validated Seniors in the Community: Risk Evaluation for Eating and Nutrition, (SCREENII-AB) by postal survey. Other measures included demographic, social and health characteristics. Physical and mental functioning and overall health-related quality of life were assessed using the 12-item Short Form Health Survey (SF-12v2). Depression was assessed using the verified shortened 10 item Center for Epidemiologic Studies Depression Scale (CES-D-10). Social provisions were determined with the 24-item Social Provisions Scale. Alcohol intake was determined by using the Alcohol Use Disorders Identification Test (AUDIT-C). Among 471 adults aged 49-87 years, 33.9% were at nutrition risk (SCREEN II-AB score ≤ 38). The direct effects of nutrition risk showed that significant differences between at-risk and not-at-risk groups at baseline remained at follow up. Over time, physical health and alcohol use scores reduced. Mental health improved over time for not-at-risk and remained static for those at-risk. Time had non-significant interactions and small effects on all other indicators. Findings highlight the importance of nutrition screening in primary care as nutrition risk factors persist over time.Item Sexual harassment or disinhibition? Residential care staff responses to older adults' unwanted behaviours(John Wiley and Sons Inc, 2022-05) Cook CM; Schouten V; Henrickson M; McDonald S; Atefi NBackground The ethical complexity of residential care is especially apparent for staff responding to residents’ inappropriate sexual expression, particularly when directed towards care workers as these residents are typically frail, often cognitively impaired, and require ongoing care. Objectives To explore staff accounts of how they made meaning of and responded to residents' unwanted sexual behaviours directed towards staff. This exploration includes whether staff appeared to accept harassment as a workplace hazard to be managed, or an unacceptable workplace violation, or something else. Methods These qualitative data are drawn from a national two-arm mixed method study in Aotearoa New Zealand undertaken in 35 residential care facilities. Semi-structured interviews were conducted with 77 staff, residents and family members. Interpretive description was used to analyse the data. Results Staff had numerous ways they used to respond to behaviours: (1) minimisation, deflection and de-escalation, where staff used strategies to minimise behaviours without requiring any accountability from residents; (2) holding residents accountable, where staff to some degree addressed the behaviour directly with residents; (3) blurred boundaries and complexities in intimate long-term care, where staff noted that in a context where touch is common-place, cognitive function was diminished and relationships were long-term, boundaries were easily breached; (4) dehumanising and infantilising residents’ behaviours, where staff appeared to assert control through diminishing the residents’ identity as an older person. It was evident that staff had developed considerable practice wisdom focused on preserving the care relationship although few referred to policy and education guiding practice. Conclusions Staff appeared to be navigating a complex ethical terrain with thoughtfulness and skill. Care workers seemed reluctant to label resident behaviour as sexual harassment, and the term may not fit for staff where they perceive residents are frail and cognitively impaired. Implications for practice Policy, education and clinical leadership are recommended to augment practice wisdom and ensure staff and resident safety and dignity and to determine how best to intervene with residents' unwanted sexual behaviours.
