Dietary Protein Intake and Determinants in Maori and Non-Maori Octogenarians. Te Puawaitanga o Nga Tapuwae Kia Ora Tonu: Life and Living in Advanced Age: A Cohort Study in New Zealand.

ABSTRACT: Protein intake, food sources and distribution are important in preventing age-related loss of muscle mass and strength. The prevalence and determinants of low protein intake, food sources and mealtime distribution were examined in 214 M?ori and 360 non-M?ori of advanced age using two 24 h multiple pass recalls. The contribution of food groups to protein intake was assessed. Low protein intake was defined as ?0.75 g/kg for women and ?0.86 g/kg for men. A logistic regression model was built to explore predictors of low protein intake. A third of both women (30.9%) and men (33.3%) had a low protein intake. The main food group sources were beef/veal, fish/seafood, milk, bread though they differed by gender and ethnicity. For women and men respectively protein intake (g/meal) was lowest at breakfast (10.1 and 13.0), followed by lunch (14.5 and 17.8) and dinner (23.3 and 34.2). Being a woman (p = 0.003) and having depressive symptoms (p = 0.029) were associated with consuming less protein. In adjusted models the odds of adequate protein intake were higher in participants with their own teeth or partial dentures (p = 0.036). Findings highlight the prevalence of low protein intake, uneven mealtime protein distribution and importance of dentition for adequate protein intake among adults in advanced age.

Protein intake, food sources and distribution are important in preventing age-related loss of muscle mass and strength.

Project description:ObjectivesSerum testosterone (T) levels in men decline with age. Low T levels are associated with sarcopenia and frailty in men aged >80 years. T levels have not previously been directly associated with disability in older men. We explored associations between T levels, frailty and disability in a cohort of octogenarian men.SettingData from all men from Life and Living in Advanced Age Cohort Study in New Zealand, a longitudinal cohort study in community-dwelling older adults.ParticipantsCommunity-dwelling (>80 years) adult men excluding those receiving T treatment or with prostatic carcinoma.Outcomes measuresAssociations between baseline total testosterone (TT) and calculated free testosterone (fT), frailty (Fried scale) and disability (Nottingham Extended Activities of Daily Living scale (NEADL)) (baseline and 24?months) were examined using multivariate regression and Wald's ?2 techniques. Subjects with the lowest quartile of baseline TT and fT values were compared with those in the upper three quartiles.ResultsParticipants: 243 men, mean (SD) age 83.7 (2.0) years. Mean (SD) TT=17.6 (6.8) nmol/L and fT=225.3 (85.4) pmol/L. On multivariate analyses, lower TT levels were associated with frailty: ?=0.41, p=0.017, coefficient of determination (R2)=0.10?and disability (NEADL) (?=-1.27, p=0.017, R2=0.11), low haemoglobin (?=-7.38, p=0.0016, R2=0.05), high fasting glucose (?=0.38, p=0.038, R2=0.04) and high C reactive protein (CRP) (?=3.57, p=0.01, R2=0.06). Low fT levels were associated with frailty (?=0.39, p=0.024, R2=0.09) but not baseline NEADL (?=-1.29, p=0.09, R2=0.09). Low fT was associated with low haemoglobin (?=-7.83, p=0.0008, R2=0.05) and high CRP (?=2.86, p=0.04, R2=0.05). Relationships between baseline TT and fT, and 24-month outcomes of disability and frailty were not significant.ConclusionsIn men over 80 years, we confirm an association between T levels and baseline frailty scores. The new finding of association between T levels and disability is potentially relevant to debates on T supplementation in older men, though, as associations were not present at 24 months, further work is needed.

Project description:BackgroundWhen COVID-19 emerged, there were well-founded fears that Māori (indigenous peoples of Aotearoa (New Zealand)) would be disproportionately affected, both in terms of morbidity and mortality from COVID-19 itself and through the impact of lock-down measures. A key way in which Kōkiri (a Māori health provider) responded was through the establishment of a pātaka kai (foodbank) that also provided a gateway to assess need and deliver other support services to whānau (in this case, client). Māori values were integral to this approach, with manaakitanga (kindness or providing care for others) at the heart of Kōkiri's actions. We sought to identify how Kōkiri operated under the mantle of manaakitanga, during Aotearoa's 2020 nationwide COVID-19 lockdown and to assess the impact of their contributions on Māori whānau.MethodsWe used qualitative methods underpinned by Māori research methodology. Twenty-six whānau interviews and two focus groups were held, one with eight kaimahi (workers) and the other with seven rangatahi (youth) kaimahi. Data was gathered between June and October 2020 (soon after the 2020 lockdown restrictions were lifted), thematically analysed and interpreted using a Māori worldview.ResultsThree key themes were identified that aligned to the values framework that forms the practice model that Kōkiri kaimahi work within. Kaitiakitanga, whānau and manaakitanga are also long-standing Māori world values. We identified that kaitiakitanga (protecting) and manaakitanga (with kindness) - with whānau at the centre of all decisions and service delivery - worked as a protective mechanism to provide much needed support within the community Kōkiri serves.ConclusionsMāori health providers are well placed to respond effectively in a public-health crisis when resourced appropriately and trusted to deliver. We propose a number of recommendations based on the insights generated from the researchers, kaimahi, and whānau. These are that: Māori be included in pandemic planning and decision-making, Māori-led initiatives and organisations be valued and adequately resourced, and strong communities with strong networks be built during non-crisis times.
