[PMID: 37049504 PMCID: PMC10096528 DOI: 10.3390/nu15071664] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 03/23/2023] [Accepted: 03/24/2023] [Indexed: 04/14/2023] Open
Abstract
The population of older adults is growing exponentially. Research shows that current protein intake recommendations are unlikely to meet the ageing requirements and may be linked to reduced physical function. Ensuring optimal function levels is crucial for independence and quality of life in older age. This study aims to quantify the protein intake in those over 90 years of age and determine the association between historical protein intake (2011) and subsequent physical function at ten years follow-up (2021). Eighty-one participants (23 Māori and 54 non-Māori) undertook dietary assessment 24 h multiple-pass recall (MPR) and a standardised health and social questionnaire with physical assessment in 2011 and 2021. Intake24, a virtual 24 h MPR, was utilised to analyse dietary intake. Functional status was measured using the Nottingham Extended Activities of Daily Living Scale (NEADL), and physical performance was the Short Physical Performance Battery (SPPB). Māori men and women consumed less protein (g/day) in 2021 than in 2011 (P = 0.043 in men), but weight-adjusted protein intake in Māori participants over the ten years was not significantly reduced. Both non-Māori men and women consumed significantly less protein (g/day) between 2011 and 2021 (p = 0.006 and p = 0.001, respectively), which was also significant when protein intake was adjusted for weight in non-Māori women (p = 0.01). Weight-adjusted protein intake in 2011 was independently associated with functional status (NEADL score) in 2021 (p =< 0.001). There was no association between past protein intake and SPPB score (p = 0.993). Animal protein was replaced with plant-based protein over time. In conclusion, a reduction in protein intake was seen in all participants. The independent association between past protein intake and future functional status supports recommendations to keep protein intake high in advanced age.

Optimising function and well-being in older adults: protocol for an integrated research programme in Aotearoa/New Zealand. BMC Geriatr 2022; 22:215. [PMID: 35296250 PMCID: PMC8925165 DOI: 10.1186/s12877-022-02845-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 02/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Maintaining independence is of key importance to older people. Ways to enable health strategies, strengthen and support whanāu (family) at the community level are needed. The Ageing Well through Eating, Sleeping, Socialising and Mobility (AWESSOM) programme in Aotearoa/New Zealand (NZ) delivers five integrated studies across different ethnicities and ages to optimise well-being and to reverse the trajectory of functional decline and dependence associated with ageing. METHODS Well-being, independence and the trajectory of dependence are constructs viewed differently according to ethnicity, age, and socio-cultural circumstance. For each AWESSoM study these constructs are defined and guide study development through collaboration with a wide range of stakeholders, and with reference to current evidence. The Compression of Functional Decline model (CFD) underpins aspects of the programme. Interventions vary to optimise engagement and include a co-developed whānau (family) centred initiative (Ngā Pou o Rongo), the use of a novel LifeCurve™App to support behavioural change, development of health and social initiatives to support Pacific elders, and the use of a comprehensive oral health and cognitive stimulation programme for cohorts in aged residential care. Running parallel to these interventions is analysis of large data sets from primary care providers and national health databases to understand complex multi-morbidities and identify those at risk of adverse outcomes. Themes or target areas of sleep, physical activity, oral health, and social connectedness complement social capital and community integration in a balanced programme involving older people across the ability spectrum. DISCUSSION AWESSoM delivers a programme of bespoke yet integrated studies. Outcomes and process analysis from this research will inform about novel approaches to implement relevant, socio-cultural interventions to optimise well-being and health, and to reverse the trajectory of decline experienced with age. TRIAL REGISTRATION The At-risk cohort study was registered by the Australian New Zealand Clinical Trials registry on 08/12/2021 (Registration number ACTRN 12621001679875 ).

[PMID: 33905878 DOI: 10.1016/j.exger.2021.111374] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 04/07/2021] [Accepted: 04/21/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND AND OBJECTIVE Physical activity (PA) confers protection to individuals from the risk of death. However, in the very old, the dose-response relationship between PA and all-cause mortality and the possible biological mediators of this association are less known. We investigated whether PA predicts 6-year all-cause mortality and what biomarkers mediate the association. DESIGN Prospective cohort data from the Tokyo Oldest Old Survey on Total Health study. SETTING Community-dwelling population. PARTICIPANTS A total of 441 women and men aged over 85 years. MEASUREMENTS Questionnaire-based PA was assessed at baseline and 3-year and 6-year follow-up visits. Survival status was confirmed up to the 6-year follow-up visit (153 deaths, 34.7%). Data of plasma albumin, cholinesterase, NT-proBNP, interleukin-6, cystatin C, and HbA1c levels were collected. For mediation analysis for survival analysis, we used the baseline PA and biomarkers with Weibull distribution accelerated failure time model and linear regression model adjusted for age, sex, body mass index, smoking, education level, and Mini-Mental State Examination. RESULTS A curvilinear relationship was observed in the association between baseline PA and all-cause mortality. Compared to the inactive (0 METs*h/week), light amount of PA was associated with a lower risk of mortality. Compared to the highest tertile of PA (11.2 METs*h/week), higher PA did not reduce the risk of death. Circulation levels of albumin and cholinesterase mediated the association between baseline PA and all-cause mortality (proportion mediated, 54%, both; p < 0.05). CONCLUSIONS Compared to completely inactive, light PA reduces the risk of all-cause mortality in the very old population. Mediation analysis suggests that protein synthesis in the liver may mediate the association between PA and all-cause mortality. Further studies are needed to understand the underlying association between PA, nutrition, and death.
