RESUMO

Genetic support for a drug target has been shown to increase the probability of success in drug development, with the potential to reduce attrition in the pharmaceutical industry alongside discovering novel therapeutic targets. It is therefore important to maximise the detection of genetic associations that affect disease susceptibility. Conventional statistical methods such as genome-wide association studies (GWAS) only identify some of the genetic contribution to disease, so novel analytical approaches are required to extract additional insights. C4X Discovery has developed Taxonomy3, a unique method for analysing genetic datasets based on mathematics that is novel in drug discovery. When applied to a previously published rheumatoid arthritis GWAS dataset, Taxonomy3 identified many additional novel genetic signals associated with this autoimmune disease. Follow-up studies using tool compounds support the utility of the method in identifying novel biology and tractable drug targets with genetic support for further investigation.

RESUMO

This study aimed to identify sociodemographic and health indicators of diet quality in pre-frail community-dwelling older adults. Pre-frail older adults are those at risk of progression to clinical manifestations of frailty and are targets for preventative intervention. We previously reported that pre-frail older adults have reasonably good overall diet quality. However, further analyses found a low intake of energy, protein and several micronutrients. METHODS: We collected detailed dietary intake from pre-frail (FRAIL scale 1-2) older adults using NZ Intake24, an online version of 24 h multiple pass dietary recall. Diet quality was ascertained with the Diet Quality Index-International (DQI-I). We used regression generalized linear models to determine predictors of diet quality as well as classification and regression tree (CART) analysis to examine the complex relationships between predictors and identified profiles of sub-groups of older adults that predict diet quality. RESULTS: The median age in this sample (n = 468) was 80.0 years (77.0-84.0). Living with others, a high deprivation index and a higher BMI were independent predictors of poorer diet quality. With CART analysis, we found that those with a BMI > 29 kg/m2, living with others and younger than 80 years were likely to have a lower diet quality. CONCLUSIONS: We found that BMI, living arrangement and socioeconomic status were independent predictors of diet quality in pre-frail older adults, with BMI being the most important variable in this sample when the interaction of these variables was considered. Future research is needed to determine the similarities and/or differences in the profile of subgroups of older adults with poorer diet quality.

RESUMO

OBJECTIVES: An increasing proportion of older people live in Retirement Villages ('villages'). This population cites support for health-care issues as one reason for relocation to villages. Here, we examine whether relocation to villages is associated with a decline in hospitalisations. METHODS: Retrospective, before-and-after observational study. SETTING: Retirement villages, Auckland, New Zealand. PARTICIPANTS: 466 cognitively intact village residents (336 [72%] female); mean (SD) age at moving to village was 73.9 (7.7) years. Segmented linear regression analysis of an interrupted time-series design was used. MAIN OUTCOME MEASURES: all hospitalisations for 18 months pre- and postrelocation to village. SECONDARY OUTCOME: acute hospitalisations during the same time periods. RESULTS: The average hospitalisation rate (per 100 person-years) was 44.9 (95% confidence interval [CI] = 36.3-55.6) 18-10 months before village relocation, 58.9 (95% CI = 48.3-72.0) 9-1 months before moving, 47.9 (95% CI = 38.8-59.1) 1-9 months after moving and 62.4 (95% CI = 51.2-76.0) 10-18 months after moving. Monthly average hospitalisation rate (per 100 person-years) increased before relocation to village by an average of 1.2 (95% CI = 0.01-1.57, p = .04) per month from 18 to 1 month before moving, and there was a change in the level of the monthly average hospitalisation rate immediately after relocation (mean difference [MD] = -18.4 per 100 person-years, 95% CI = -32.8 to -4.1, p = .02). The trend change after village relocation did not differ significantly from that before moving. CONCLUSIONS: Although we cannot reliably claim causality, relocation to a retirement village is, for older people, associated with a significant but non-sustained reduction in hospitalisation.

RESUMO

Introduction Physical activity (PA) in older people is associated with improved morbidity and mortality outcomes. Increasing numbers of older people are choosing to live in retirement villages, many of which promote themselves as providing opportunities for activity. Aim To explore the characteristics of PA village residents were undertaking and the associated individual and village factors. Methods Health, functional and wellbeing information was collected from 577 residents recruited from 34 villages in Auckland, New Zealand, using an International Resident Assessment Instrument and customised survey tools containing items on self-reported PA. Managers from villages completed a survey on village characteristics and facilities. Results The mean age (s.d.) of village residents was 82 (7) years, and 325 (56%) reporting doing one or more hours of PA in the 3 days prior to assessment. Moderate exercise was performed by 240 (42%) village residents, for a mean (s.d.) of 2.7 (3.4) h per week. The most common activities provided by villages included: bowls/petanque (22, 65%) and exercise classes (22, 65%), and walking was the most common activity undertaken (348, 60%). Factors independently associated with PA included individual factors (gender, fatigue, constipation, self-reported health, number of medications, moving to village for safety and security, utilising village fitness programme, use of the internet, and satisfaction with opportunities to be active) and village-related factors (access to unit, and ownership model). Discussion PA uptake is determined by many factors at both personal (physical and psychosocial) and environmental levels. Clinicians should focus on individualised PA promotion in those with identified risk factors for low levels of PA.

RESUMO

BACKGROUND: Atrial fibrillation (AF), the most common cardiac arrhythmia in the general population, has significant healthcare burden. Little is known about AF in octogenarians. OBJECTIVE: To describe the prevalence and incidence rate of AF in New Zealand (NZ) octogenarians and the risk of stroke and mortality at 5-year follow-up. DESIGN: Longitudinal Cohort Study. SETTING: Bay of Plenty and Lakes health regions of New Zealand. SUBJECTS: Eight-hundred-seventy-seven (379 indigenous Maori, 498 non-Maori) were included in the analysis. METHODS: AF, stroke/TIA events and relevant co-variates were established annually using self-report and hospital records (and ECG for AF). Cox proportional-hazards regression models were used to determine the time dependent AF risk of stroke/TIA. RESULTS: AF was present in 21% at baseline (Maori 26%, non-Maori 18%), the prevalence doubled over 5-years (Maori 50%, non-Maori 33%). 5-year AF incidence was 82.6 /1000-person years and at all times AF incidence for Maori was twice that of non-Maori. Five-year stroke/TIA prevalence was 23% (22% in Maori and 24% non- Maori), higher in those with AF than without. AF was not independently associated with 5-year new stroke/TIA; baseline systolic blood pressure was. Mortality was higher for Maori, men, those with AF and CHF and statin use was protective. In summary, AF is more prevalent in indigenous octogenarians and should have an increased focus in health care management. Further research could examine treatment in more detail to facilitate ethnic specific impact and risks and benefits of treating AF in octogenarians.

RESUMO

PURPOSE: Seasonal variation of acute diverticular disease is variably reported in observational studies. This study aimed to describe seasonal variation of acute diverticular disease hospital admissions in New Zealand. METHODS: A time series analysis of national diverticular disease hospitalisations from 2000 to 2015 was conducted among adults aged 30 years or over. Monthly counts of acute hospitalisations' primary diagnosis of diverticular disease were decomposed using Census X-11 times series methods. A combined test for the presence of identifiable seasonality was used to determine if overall seasonality was present; thereafter, annual seasonal amplitude was calculated. The mean seasonal amplitude of demographic groups was compared by analysis of variance. RESULTS: Over the 16-year period, 35,582 hospital admissions with acute diverticular disease were included. Seasonality in monthly acute diverticular disease admissions was identified. The mean monthly seasonal component of acute diverticular disease admissions peaked in early-autumn (March) and troughed in early-spring (September). The mean annual seasonal amplitude was 23%, suggesting on average 23% higher acute diverticular disease hospitalisations during early-autumn (March) than in early-spring (September). The results were similar in sensitivity analyses that employed different definitions of diverticular disease. Seasonal variation was less pronounced in patients aged over 80 (p = 0.002). Seasonal variation was significantly greater among Maori than Europeans (p < 0.001) and in more southern regions (p < 0.001). However, seasonal variations were not significantly different by gender. CONCLUSIONS: Acute diverticular disease admissions in New Zealand exhibit seasonal variation with a peak in Autumn (March) and a trough in Spring (September). Significant seasonal variations are associated with ethnicity, age, and region, but not with gender.

RESUMO

AIMS: Frailty within the older adult rehabilitation population is relatively under-explored. We aimed to derive a frailty index (FI) from electronic routinely collected data to determine frailty prevalence, and to assess its ability to predict adverse outcomes in the rehabilitation setting. METHODS: A FI was derived and retrospectively applied to electronically recorded health information of older adults admitted for inpatient rehabilitation. For analysis, subjects were allocated into frailty score (FS) groups (0-5). Primary outcome was a six-month hospitalistion rate, and other outcomes were: mortality, entrance into long-term care (LTC) at one year, length of stay (LOS), 30- and 90-day hospitalistions. Univariate and multivariable logistic regressions analysed associations between frailty and outcomes. RESULTS: One hundred and sixty-two patient electronic notes were reviewed. Mean (SD) age was 86 (8.2) years, 147 (90.7%) were considered frail (FS>0.25). The most frail group (FS 5) had higher risk of six-month hospitalisations (OR=6.19; 95%CI=1.82, 21.13; p=0.004). A higher frailty score was associated with shorter LOS compared to lowest frailty scores (15.7 days vs 25.4 days; p=0.04). No relationship was found with shorter-term outcomes. CONCLUSION: Prevalence of frailty is high in the rehabilitation setting. Association of frailty with shorter LOS and lack of association found with shorter-term outcomes warrant further study.

RESUMO

OBJECTIVES: There is evidence that loneliness is detrimental to the subjective well-being of older adults. However, little is known on this topic for the cohort of those in advanced age (80 years or older), which today is the fastest-growing age group in the New Zealand population. We examined the relationships between loneliness and selected subjective well-being outcomes over 5 years. METHODS: We used a regional, bicultural sample of those in advanced age from 2010 to 2015 (Life and Living in Advanced Age: a Cohort Study in New Zealand). The first wave enrolled 937 people (92% of whom were living in the community): 421 Maori (Indigenous New Zealanders aged 80-90 years) and 516 non-Maori aged 85 years. We applied standard regression techniques to baseline data and mixed-effects models to longitudinal data, while adjusting for sociodemographic factors. RESULTS: For both Maori and non-Maori, strong negative associations between loneliness and subjective well-being were found at baseline. In longitudinal analyses, we found that loneliness was negatively associated with life satisfaction as well as with mental health-related quality of life. DISCUSSION: Our findings of adverse impacts on subjective well-being corroborate other evidence, highlighting loneliness as a prime candidate for intervention-appropriate to cultural context-to improve well-being for adults in advanced age.

RESUMO

Chronic pain is common in older people. However, little is known about how pain is experienced in residents of retirement villages ('villages'), and how pain intensity and associations are experienced in relation to characteristics of residents and village living. We thus aimed to examine pain levels, prevalence and associated factors in village residents. The current paper is a cross-sectional analysis of baseline data from the 'Older People in Retirement Villages' study in Auckland, New Zealand. Between July 2016 and August 2018, 578 village residents were interviewed face-to-face by gerontology nurse specialists, using interRAI Community Health Assessment (CHA) and customised survey. We used a validated pain scale and multivariable logistic regression analyses adjusted for pre-specified confounders. Residents' median age was 82 years; 420 (73%) were female; 270 (47%) exhibited/reported daily pain, and in 11% this was severe. After controlling for confounders, daily pain was positively associated with self-reported arthritis (OR = 3.88, 95% CI = 2.57-5.87), poor/fair self-reported health (OR = 3.19, 95% CI = 1.29-7.93), having no health clinic on-site (OR = 1.76, 95% CI = 1.10-2.83), and minimal fatigue (diminished energy but completes normal day-to-day activities) (OR = 1.77, 95% CI = 1.11-2.81). Similar associations were observed for levels of pain. We conclude that levels of pain and prevalence of daily pain are high in village residents. Self-reported arthritis, self-reported poor/fair health, no health clinic on-site and minimal fatigue are all independently associated with a higher risk of daily pain and with levels of pain. This study suggests potential opportunities for villages to better provide on-site support to decrease prevalence and severity of pain for their residents, and thus potentially increase wellbeing and quality-of-life, though as we cannot prove causality, more research is needed.

RESUMO

OBJECTIVES: As people age, they are more likely to require support to maintain activities of daily living. Referral for formal assessment of need (assessed using the 'international Resident Assessment Instrument' [interRAI]) is the first step to access publicly funded services in Aotearoa New Zealand (NZ). It is unclear whether ethnic access inequities present in other areas of the NZ health system occur in this referral process. This exploratory research aimed to explore ethnic variation in referrals for interRAI assessment, and associated factors. METHODS: A retrospective cohort study of all new referrals for aged care services for those 55-plus, received in 2018 by Waitemata District Health Board (WDHB), was conducted. The primary outcome was referral outcome (assessment and no assessment). Secondary outcomes included time from referral to assessment, reason for referral, mortality and, in the assessed cohort, assessment outcome. RESULTS: New referrals (n = 3263) were ethnically representative of the general older adult population in WDHB. Maori were younger and more likely to be referred for higher-level care needs than non-Maori, non-Pasifika (NMNP) (p = 0.03). There was no significant difference in referral outcome, time to assessment or mortality between ethnicities. NMNP were more likely to access lower-level care services than Maori or Pasifika older adults (p = 0.002). CONCLUSIONS: Ethnicity was not associated with aged care service assessment access once people were referred for publicly funded services, nor was it associated with time to assessment or mortality in this exploratory study. Maori had higher care needs than NMNP at the time of referral.

RESUMO

OBJECTIVES: 11% of drivers aged 65+ report moderate to extreme driving anxiety, with associated reduction in driving. Knowledge about the relationships of driving anxiety with health and quality of life for older people is minimal. The present study examined these relationships. METHOD: 1170 community dwelling drivers aged 65+ in New Zealand completed a population survey. RESULTS: After adjusting for socio-demographic variables, higher driving anxiety was associated with lower quality of life and lower odds of 'very good' self-reported health, but no difference in odds of multi-comorbidity. DISCUSSION: Further research is needed to examine the influence of driving anxiety on health and quality of life outcomes with a broader range of older people who experience more challenges to their health and wellbeing, especially to mental health.

RESUMO

OBJECTIVES: The development of frailty tools from electronically recorded healthcare data allows frailty assessments to be routinely generated, potentially beneficial for individuals and healthcare providers. We wished to assess the predictive validity of a frailty index (FI) derived from interRAI Community Health Assessment (CHA) for outcomes in older adults residing in retirement villages (RVs), elsewhere called continuing care retirement communities. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: 34 RVs across two district health boards in Auckland, Aotearoa New Zealand (NZ). 577 participants, mean age 81 years; 419 (73%) female; 410 (71%) NZ European, 147 (25%) other European, 8 Asian (1%), 7 Maori (1%), 1 Pasifika (<1%), 4 other (<1%). METHODS: interRAI-CHA FI tool was used to stratify participants into fit (0-0.12), mild (>0.12-0.24), moderate (>0.24-0.36) and severe (>0.36) frail groups at baseline (the latter two grouped due to low numbers of severely frail). Primary outcome was acute hospitalization; secondary outcomes included long-term care (LTC) entry and mortality. The relationship between frailty and outcomes were explored with multivariable Cox regression, estimating hazard ratios (HRs) and 95% confidence intervals (95%CIs). RESULTS: Over mean follow-up of 2.5 years, 33% (69/209) of fit, 58% (152/260) mildly frail and 79% (85/108) moderate-severely frail participants at baseline had at least one acute hospitalization. Compared to the fit group, significantly increased risk of acute hospitalization were identified in mildly frail (adjusted HR = 1.88, 95%CI = 1.41-2.51, p<0.001) and moderate-severely frail (adjusted HR = 3.52, 95%CI = 2.53-4.90, p<0.001) groups. Similar increased risk in moderate-severely frail participants was seen in LTC entry (adjusted HR = 5.60 95%CI = 2.47-12.72, p<0.001) and mortality (adjusted HR = 5.06, 95%CI = 1.71-15.02, p = 0.003). CONCLUSIONS AND IMPLICATIONS: The FI derived from interRAI-CHA has robust predictive validity for acute hospitalization, LTC entry and mortality. This adds to the growing literature of use of interRAI tools in this way and may assist healthcare providers with rapid identification of frailty.

RESUMO

BACKGROUND: To study healthcare utilization and trajectories, and associated factors, in older adults in retirement villages (RVs), also known as continuing care retirement communities. METHODS: Prospective cohort study of 578 cognitively intact residents from 34 RVs in Auckland, New Zealand (NZ). MEASUREMENT: InterRAI-Community Health Assessment (includes core items that may trigger functional supplement (FS) completion in those with higher needs, and generates clinical assessment protocols (CAPs) in those with potential unmet needs). OUTCOMES: time to acute hospitalization, long-term care (LTC), and death during average 2.5 years follow-up. RESULTS: Three hundred seven (53%) residents had acute hospitalizations, 65 (11%) moved to LTC, and 51 (9%) died over a mean of 2.5 years. Factors associated with increased risk of acute hospitalization included CAP-falls (high risk) triggered, number of comorbidities, not having left RV in 2 weeks prior, moderate/severe hearing impairment, CAP-cardiorespiratory conditions triggered, acute hospitalization in year prior and age, with significant hazard ratios (HR) ranging between 1.03 and 2.90. Factors associated with reduced risk of hospitalization included other (non-NZ) European ethnicity (HR 0.73, 95% CI 0.55-0.98, p = 0.04), presence of on-site clinic (HR 0.62, 95% CI 0.45-0.85, p = 0.003), no influenza vaccination (HR 0.56, 95% CI 0.38-0.83, p = 0.004). Factors associated with LTC transition included FS triggered (HR 3.84, 95% CI 1.92-7.66, p < 0.001), CAP-instrumental activities of daily living (IADL) (HR 2.62, 95% CI 1.22-5.62, p = 0.01), CAP-social relationship triggered (HR 2.00, 95% CI 1.13-3.55, p = 0.02), and age (HR 1.13, 95% CI 1.07-1.18 p < 0.001). Factors associated with mortality included number of comorbidities (HR 3.75, 95% CI 1.54-9.10, p = 0.004 for 3-5 comorbidities), CAP-IADL triggered (HR 3.05, 95% CI 1.30-7.16, p = 0.01), and age (HR 1.11, 95% CI 1.05-1.18, p < 0.001). CONCLUSION: A large proportion of cognitively intact RV residents are admitted to hospital in mean 2.5 years of follow-up. Multiple factors were associated with acute hospitalization risk. On-site clinics were associated with reduced risk and should be considered in RV development.

RESUMO

BACKGROUND: Retirement villages (RVs), also known as continuing care retirement communities, are an increasingly popular housing choice for older adults. The RV population has significant health needs, possibly representing a group with needs in between community-dwelling older adults and those in long-term residential care (LTC). Our previous work shows Gerontology Nurse Specialist (GNS)-facilitated multidisciplinary team (MDT) interventions may reduce hospitalizations from LTC. This study tested whether a similar intervention reduced hospitalizations in RV residents. METHODS: Open-label randomized controlled trial in which 412 older residents of 33 RVs were randomized (1:1) to an MDT intervention or usual care. SETTING: RVs across two District Health Boards in Auckland, New Zealand. Residents were eligible if considered high risk of health/functional decline (triggering ≥3 interRAI Clinical Assessment Protocols or needing special consideration identified by GNS). INTERVENTION: GNS-facilitated MDT intervention, including geriatrician/nurse practitioner and clinical pharmacist, versus usual care. Primary outcome was time from randomization to first acute hospitalization. Secondary outcomes were rate of acute hospitalizations, LTC admission, and mortality. Twelve residents died before randomization; all others (n = 400: MDT intervention = 199; usual care = 201) were included in intention-to-treat analyses. RESULTS: Mean (SD) age was 82.2 (6.9) years, 302 (75.5%) were women, and 378 (94.5%) were European. Over median 1.5 years follow-up, no difference was found in hazard of acute hospitalization between the MDT intervention (51.8%) and usual care (49.3%) groups (Hazard ratio [HR] = 1.01, 95% CI = 0.77-1.34). No difference was found in the incidence rate of acute hospitalizations between the MDT intervention (0.69 per person-year) and usual care (0.86 per person-year) groups (incidence rate ratio = 0.81, 95% CI = 0.59-1.10). Similar results were seen for the proportion of residents with LTC transition (HR = 1.18, 95% CI = 0.65-2.11) and mortality (HR = 0.70, 95% CI = 0.36-1.35). CONCLUSION: Further studies are needed to assess the effects of other patient-centered interventions and outcomes with adequate primary care integration.

RESUMO

INTRODUCTION te Tiriti o Waitangi guarantees Maori the right to: self-determination, equitable health outcomes, be well informed, health care options, including kaupapa Maori and culturally safe mainstream services, and partnership in the health care journey. Despite integration of these principles into policy, there remains a lack of application in health service development, and health inequities remain. AIM We aimed to use te Tiriti o Waitangi to structure the development of a culturally safe health intervention, using as an exemplar pharmacist-facilitated medicines review for Maori older adults. METHODS Previous research undertaken by our group (a systematic review, and interviews with stakeholders including Maori older adults) was used to inform the aspects to include in the intervention. Kaupapa Maori theory was used to underpin the approach. Intended outcomes, requirements for change, and outcome measures to assess change were mapped to te Tiriti o Waitangi principles as a way to structure the pharmacist-facilitated medicines review intervention and research processes. RESULTS Findings from our previous research identified 12 intended intervention outcomes, including that the intervention be flexible to adapt to diverse needs in a way that is acceptable and culturally safe for Maori and that it supports Maori older adults to control and have confidence in their medicine treatment and wellbeing. DISCUSSION We present an approach to the development of a pharmacist-facilitated medicines review intervention for Maori older adults, structured around the principles of te Tiriti o Waitangi, to support the implementation of a culturally safe, pro-equity intervention.

This study aimed to describe the diet quality of pre-frail community-dwelling older adults to extend the evidence of nutrition in frailty prevention. Pre-frailty, the transition state between a robust state and frailty, was ascertained using the FRAIL scale. Socio-demographic, health status, and 24-h dietary recalls were collected from 465 community-dwelling adults aged 75+ (60 years for Maori and Pacific people) across New Zealand. Diet quality was ascertained with the Diet Quality Index-International (DQI-I). Participants (median (IQR) age 80 (77-84), 59% female) had a moderately healthful diet, DQI-I score: 60.3 (54.0-64.7). Women scored slightly higher than men (p = 0.042). DQI-I components identified better dietary variety in men (p = 0.044), and dietary moderation in women (p = 0.002); both sexes performed equally well in dietary adequacy and poorly in dietary balance scores (73% and 47% of maximum scores, respectively). Low energy 20.3 (15.4-25.3) kcal/kg body weight (BW) and protein intakes 0.8 (0.6-1.0) g/kg BW were coupled with a high prevalence of mineral inadequacies: calcium (86%), magnesium (68%), selenium (79%), and zinc (men 82%). In conclusion, the diet quality of pre-frail older adults was moderately high in variety and adequacy but poor in moderation and balance. Our findings support targeted dietary interventions to ameliorate frailty.

RESUMO

While there have been significant advances in drug discovery for diabetes mellitus over the past couple of decades, there is an opportunity and need for improved therapies. While type 2 diabetic patients better manage their illness, many of the therapeutics in this area are peptide hormones with lengthy sequences and a molecular structure that makes them challenging and expensive to produce. Using machine learning, we present novel anti-diabetic peptides which are less than 16 amino acids in length, distinct from human signalling peptides. We validate the capacity of these peptides to stimulate glucose uptake and Glucose transporter type 4 (GLUT4) translocation in vitro. In obese insulin-resistant mice, predicted peptides significantly lower plasma glucose, reduce glycated haemoglobin and even improve hepatic steatosis when compared to treatments currently in use in a clinical setting. These unoptimised, linear peptides represent promising candidates for blood glucose regulation which require further evaluation. Further, this indicates that perhaps we have overlooked the class of natural short linear peptides, which usually come with an excellent safety profile, as therapeutic modalities.

RESUMO

OBJECTIVES: Retirement villages are semi-closed communities, access usually being gained via village managers. This paper explores issues recruiting a representative resident cohort, as background to a study of residents, to acquire sociodemographic, health and disability data and trial an intervention designed to improve outcomes. METHODS: We planned approaching all Auckland/Waitemata District villages and, via managers, contacting residents ('letter-drop'; 'door-knocks'). In 'small' villages (n ≤ 60 units), we planned contacting all residents, randomly selecting in 'larger' villages. We excluded those with doubtful or absent legal capacity. RESULTS: We approached managers of 53 of 65 villages. Thirty-four permitted recruitment. Some prohibited 'letter-drops' and/or 'door-knocks'. Hence, we recruited volunteers (23 villages) via meetings, posters, newsletters and word-of-mouth, that is representative sampling obtained from 11/34 villages. We recruited 578 residents (median age = 82 years; 420 = female; 217:361 sampled:volunteers), finding differences in baseline parameters of sampled vs. volunteers. CONCLUSION: Due to organisational/managers' policy, and national legislation restrictions, our sample does not represent our intended population well. Researchers should investigate alternative data sources, for example electoral rolls and censuses.
