Do financial hardships affect health? A study among older adults in Switzerland.

BACKGROUND: A growing number of studies have underlined the relationship between socioeconomic status and health. Following that literature, we explore the causal effect of financial hardships on changes in health at older ages. Rather than traditional measures of socioeconomic variables, we study the role of financial hardships. The declarative measurement of financial hardships is particularly relevant for assessing the impact of short-term financial difficulties on health among older adults. METHODS: In this study, we use data from the Lausanne cohort 65+. Participants are community-dwelling older adults representative of the population aged 65-70 years in 2004 and living in Lausanne (Switzerland) (n = 1352). We use longitudinal annual data with 11 years of follow-up (2006-16) to estimate dynamic panel models on several indicators measuring older adults' health (self-rated health, number of medical conditions, depressive symptoms, difficulties with daily living activities). RESULTS: We find evidence of causal effects of financial hardships on self-rated health (coef. = 0.059, P < 0.10) and on depressive symptoms (coef.=0.060, P < 0.05). On the other hand, we find no evidence of causality running from financial hardships to the number of medical conditions and the difficulties in daily living activities. CONCLUSION: These results make a contribution to the literature where nearly all previous research on associations between financial hardship and health does not establish causal relationships. Our results support the need to integrate health policies that mitigate the potential adverse health effects of financial hardship for older adults.

Executive function and prospective falls: a 6-year longitudinal study in community-dwelling older adults.

BACKGROUND: Older people with impaired executive function (EF) might have an increased fall risk, but prospective studies with prolonged follow-up are scarce. This study aimed to investigate the association between a) EF at baseline; b) 6-year decline in EF performance; and fall status 6 years later. METHODS: Participants were 906 community-dwelling adults aged 65-69 years, enrolled in the Lausanne 65 + cohort. EF was measured at baseline and at 6 years using clock drawing test (CDT), verbal fluency (VF), Trail Making Test (TMT) A and B, and TMT ratio (TMT-B - TMT-A/TMT-A). EF decline was defined as clinically meaningful poorer performance at 6 years. Falls data were collected at 6 years using monthly calendars over 12 months. RESULTS: Over 12-month follow-up, 13.0% of participants reported a single benign fall, and 20.2% serious (i.e., multiple and/or injurious) falls. In multivariable analysis, participants with worse TMT-B performance (adjusted Relative Risk Ratio, adjRRRTMT-B worst quintile = 0.38, 95%CI:0.19-0.75, p = .006) and worse TMT ratio (adjRRRTMT ratio worst quintile = 0.31, 95%CI:0.15-0.64, p = .001) were less likely to report a benign fall, whereas no significant association was observed with serious falls. In a subgroup analysis among fallers, participants with worse TMT-B (OR:1.86, 95%CI = 0.98-3.53, p = .059) and worse TMT ratio (OR:1.84,95%CI = 0.98-3.43,p = .057) tended to have higher odds of serious falls. EF decline was not associated to higher odds of falls. CONCLUSIONS: Participants with worse EF were less likely to report a single benign fall at follow-up, while fallers with worse EF tended to report multiple and/or injurious falls more frequently. Future studies should investigate the role of slight EF impairment in provoking serious falls in active young-old adults.

Fear of falling and all-cause mortality among young-old community-dwelling adults: a 6-year prospective study.

This study investigated whether fear of falling (FOF) measured by two different instruments, the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR), is associated with mortality at 6-year follow-up. Participants (n = 1359, 58.6% women) were community-dwelling persons enrolled in the Lausanne cohort 65 + , aged 66 to 71 years at baseline. Covariables assessed at baseline included demographic, cognitive, affective, functional and health status, while date of death was obtained from the office in charge for population registration. Unadjusted Kaplan Meyer curves were performed to show the survival probability for all-cause mortality according to the degree of FOF reported with FES-I and SQ-FAR, respectively. Bivariable and multivariable Cox regression analyses were performed to assess hazard ratios, using time-in-study as the time scale variable and adjusting for variables significantly associated in bivariable analyses. During the 6-year follow-up, 102 (7.5%) participants died. Reporting the highest level of fear at FES-I (crude HR 3.86, 95% CI 2.37-6.29, P < .001) or "FOF with activity restriction" with SQ-FAR (crude HR 2.42, 95% CI 1.44-4.09, P = .001) were both associated with increased hazard of death but these associations did not remain significant once adjusting for gender, cognitive, affective and functional status. As a conclusion, although high FOF and related activity restriction, assessed with FES-I and SQ-FAR, identifies young-old community-dwelling people at increased risk of 6-year mortality, this association disappears when adjusting for potential confounders. As a marker of negative health outcomes, FOF should be screened for in order to provide personalized care and reduce subsequent risks.

Development and validation of a knowledge-based score to predict Fried's frailty phenotype across multiple settings using one-year hospital discharge data: The electronic frailty score.

Background: Most claims-based frailty instruments have been designed for group stratification of older populations according to the risk of adverse health outcomes and not frailty itself. We aimed to develop and validate a tool based on one-year hospital discharge data for stratification on Fried's frailty phenotype (FP). Methods: We used a three-stage development/validation approach. First, we created a clinical knowledge-driven electronic frailty score (eFS) calculated as the number of deficient organs/systems among 18 critical ones identified from the International Statistical Classification of Diseases and Related Problems, 10th Revision (ICD-10) diagnoses coded in the year before FP assessment. Second, for eFS development and internal validation, we linked individual records from the Lc65+ cohort database to inpatient discharge data from Lausanne University Hospital (CHUV) for the period 2004-2015. The development/internal validation sample included community-dwelling, non-institutionalised residents of Lausanne (Switzerland) recruited in the Lc65+ cohort in three waves (2004, 2009, and 2014), aged 65-70 years at enrolment, and hospitalised at the CHUV at least once in the year preceding the FP assessment. Using this sample, we selected the best performing model for predicting the dichotomised FP, with the eFS or ICD-10-based variables as predictors. Third, we conducted an external validation using 2016 Swiss nationwide hospital discharge data and compared the performance of the eFS model in predicting 13 adverse outcomes to three models relying on well-designed and validated claims-based scores (Claims-based Frailty Index, Hospital Frailty Risk Score, Dr Foster Global Frailty Score). Findings: In the development/internal validation sample (n = 469), 14·3% of participants (n = 67) were frail. Among 34 models tested, the best-subsets logistic regression model with four predictors (age and sex at FP assessment, time since last hospital discharge, eFS) performed best in predicting the dichotomised FP (area under the curve=0·71; F1 score=0·39) and one-year adverse health outcomes. On the external validation sample (n = 54,815; 153 acute care hospitals), the eFS model demonstrated a similar performance to the three other claims-based scoring models. According to the eFS model, the external validation sample showed an estimated prevalence of 56·8% (n = 31,135) of frail older inpatients at admission. Interpretation: The eFS model is an inexpensive, transportable and valid tool allowing reliable group stratification and individual prioritisation for comprehensive frailty assessment and may be applied to both hospitalised and community-dwelling older adults. Funding: The study received no external funding.

Instrumented 5-Time Sit-To-Stand Test: Parameters Predicting Serious Falls beyond the Duration of the Test.

BACKGROUND: Falls are a major cause of injuries in older adults. To evaluate the risk of falls in older adults, clinical assessments such as the 5-time sit-to-stand (5xSTS) test can be performed. The development of inertial measurement units (IMUs) has provided the possibility of a more in-depth analysis of the movements' biomechanical characteristics during this test. The goal of the present study was to investigate whether an instrumented 5xSTS test provides additional information to predict multiple or serious falls compared to the conventional stopwatch-based method. METHODS: Data from 458 community-dwelling older adults were analyzed. The participants were equipped with an IMU on the trunk to extract temporal, kinematic, kinetic, and smoothness movement parameters in addition to the total duration of the test by the stopwatch. RESULTS: The total duration of the test obtained by the IMU and the stopwatch was in excellent agreement (Pearson's correlation coefficient: 0.99), while the total duration obtained by the IMU was systematically 0.52 s longer than the stopwatch. In multivariable analyses that adjusted for potential confounders, fallers had slower vertical velocity, reduced vertical acceleration, lower vertical power, and lower vertical jerk than nonfallers. In contrast, the total duration of the test measured by either the IMU or the stopwatch did not differ between the 2 groups. CONCLUSIONS: An instrumented 5xSTS test provides additional information that better discriminates among older adults those at risk of multiple or serious falls than the conventional stopwatch-based assessment.

Trajectories of phenotypical frailty over a decade in young-old community-dwelling adults: results from the Lc65+ study.

BACKGROUND: Few studies have examined the frailty trajectories of young-old adults using Fried frailty phenotype. Dropouts due to death were rarely taken into account. This longitudinal study aimed to identify trajectories with and without adjustment for non-random attrition and to analyse related factors. METHODS: We used the first two samples of community-dwelling people in the Lausanne cohort 65+. Frailty phenotype was assessed at age 66-71 years and every third year over 10 years. A group-based trajectory modelling-first without and then with adjustment for non-random attrition-identified trajectories among all individuals with at least two observations (n=2286), excluding dropouts for reasons other than death. Multinomial logistic regressions estimated independent effects of participants' baseline characteristics. RESULTS: We identified three frailty trajectories (low, medium and high). Participants in the highest trajectory had a higher mortality over 10 years. (Pre)frailty at baseline was the main factor associated with adverse trajectories. Smoking, obesity, comorbidity and negative self-perceived health were associated with unfavourable trajectories independently of baseline frailty, while social engagement was related to the lowest frailty trajectory. Ignoring transitions to death attenuated the estimated effects of age on trajectories. CONCLUSIONS: Fried frailty phenotype should be assessed in individuals aged late 60s as it is strongly associated with frailty trajectories in the following decade of their life. Lifetime prevention of behavioural risk factors such as smoking and obesity is the strategy most likely to influence the development of frailty in older populations. Furthermore, our results underline social engagement as an important area of interest for future research.

Does the frailty phenotype at the age of 66 to 71 predict death? A 14-year survival analysis of the Lc65+ study.

BACKGROUND: Frailty is a health characteristic resulting from the loss of physiological reserve of multiple organs, leading to exposure to adverse outcomes, and is possibly reversible in its earliest stages. It is identified by a specific phenotype that contributes to the practice of geriatric medicine, where it is considered a potential target for preventive action. This phenotype has recently attracted interest in other medical specialties for risk assessment before stressful interventions in older adults. Whereas frailty is unusual in sexagenarians, pre-frailty is common. This longitudinal study aimed to evaluate the significance of fulfilling at least one criterion of the frailty phenotype in the late sixties as a predictor of short- and long-term mortality in males and females. METHODS: Data came from the first sample of the Lc65+ cohort, representative of the community-dwelling Lausanne population born between 1934 and 1939 (n = 1315). After baseline assessment of the five criteria of Fried's frailty phenotype (shrinking, exhaustion, muscular weakness, motor slowness and low physical activity) in 2005 (age 66-71 years), deaths were recorded over 14 years. We separated individuals into non-frail (fulfilling 0 criterion) and (pre-)frail (1+ criteria). The relationship between the phenotype and mortality was investigated graphically using Kaplan-Meier survival curves and quantified in Cox models. Multivariable analyses incrementally controlled age, socioeconomic and health characteristics. The prediction of fully adjusted models was evaluated using the Harrell's C index. RESULTS: Overall, 401 persons (30.5%) were (pre-)frail at baseline. A quarter of the 1315 participants died over 14 years (n = 336, 25.6%). The mortality rate was significantly higher in males in the (pre-)frail subgroup only. Survival curves showed a significant effect of (pre-)frailty on the risk of dying for both sexes. The effect of (pre-)frailty on mortality was stronger during the first 4 years of the follow-up. In males, it was significant both in short (0-4 years) and longer (>4-14 years) terms. In females, it was significant in the short term only. In all models, the estimated effect was stronger in males. The fully adjusted model was fairly predictive of death in the short term both in males (Harrell's C 0.79) and females (0.75). CONCLUSIONS: The significantly higher mortality of individuals presenting 1+ frailty criteria supports the appropriateness of a systematic assessment of the frailty phenotype at the age of 66-71 years. In both females and males, early identification of pre-frailty has the potential to limit or reverse the development of frailty and extend lifespan through adequate individual management.

Potentially inappropriate prescriptions: Associations with the health insurance contract and the quality of the patient-physician relationship?

CONTEXT: Potentially Inappropriate Prescriptions (PIP) are often used as an indicator of potential drug overuse or misuse to limit adverse drug events in older people. OBJECTIVE: To determine whether PIP exposure differs as a function of the patient's health insurance scheme and the patient-physician relationship. METHODS: Our dataset was collected from two surveys delivered to two cohorts of the Swiss Lc65+ study, together with a stratified random sample of older people in the Swiss canton of Vaud. The study sample consisted of 1,595 people aged 68 years and older living in the community and reporting at least one prescription drug. Logit regression models of PIP risk were run for various categories of variables: health related, socioeconomic, health insurance scheme and patient-physician relationship. RESULTS: 17% of our respondents had at least one PIP. Our results suggested that being enrolled in a health plan with restriction in the patient's choice of providers and having higher deductibles were associated with lower PIP risk. PIP risk did not differ as a function of the quality of the patient-physician relationship. CONCLUSION: Our study helps to raise awareness about the organizational risk factors of PIP and, more specifically, how health insurance contracts could play a role in improving the management of drug consumption among community-dwelling older people.

Slowness Predicts Mortality: A Comparative Analysis of Walking Speed and Moberg Picking-Up Tests.

OBJECTIVES: Slow walking speed (WS) is predictive of mortality but may be difficult to measure, which compromises the assessment of frailty, based on Fried et al's phenotype. The timed Moberg picking-up test (MPUT), developed to evaluate hand's function, was found moderately but significantly correlated with WS. We compared the relationship between slowness, assessed by MPUT and WS tests, and mortality. DESIGN: Observational (prospective cohort study). SETTING AND PARTICIPANTS: 4731 community-dwelling adults included in 2004, 2009, or 2014 in the ongoing Lausanne cohort 65+ (Lc65+) were assessed at the age of 66-71 years. METHOD: Mortality was compared for individuals above and below percentile 80 of MPUT, and respectively WS performance time, according to the Fried criterion. Multivariable analysis using Cox's regression models were adjusted for age, sex, height and grip strength. The predictive capability of MPUT and WS was assessed in adjusted models using Harrell C. RESULTS: Slowness in MPUT and in WS test was associated with mortality at 4, 9, and 14 years (P < .001). Survival curves showed lower survival rates in the highest percentile for both tests (P < .001), regardless of the follow-up period. Cox models indicated a higher risk of death at 4 years [adjusted hazard ratio (95% confidence interval): MPUT, 2.1 (1.5-3.0); WS, 2.2 (1.5-3.1)], 9 years [MPUT 1.7 (1.3-2.3); WS 2.0 (1.5-2.6)] and 14 years [MPUT 1.8 (1.4-2.3); WS 1.8 (1.4-2.4)] for participants above the 80th percentile (all P < .001). The 2 tests had similar predictive capability (Harrell C: MPUT, between 61% and 68%; WS, between 62% and 69%). CONCLUSIONS AND IMPLICATIONS: Poor performance in MPUT is associated with increased mortality at the short and long term among community-dwelling older adults. This alternative to WS in the assessment of slowness has similar predictive capability for mortality and avoids biased estimates because of nonrandom exclusion of individuals unable to complete WS.

Older People's Health-Related Behaviors: Evidence from Three Cohorts of the Lc65+ Study.

Baby-boomers might be more health-conscious than earlier birth cohorts, but limited evidence has been produced so far. To investigate such changes, this study compared health-related behaviors at age 65 to 70 among three successive five-year birth cohorts (pre-war: born 1934-1938; war: born 1939-1943 and baby-boom: born 1944-1948) representative of the community-dwelling population. Information about alcohol use, smoking, physical activity, and nutrition was compared across the three cohorts (n = 4,270 participants) using Chi-squared test. Alcohol and the mean nutritional intake score did not vary across cohorts, whereas the consumption of nonalcoholic drinks increased significantly from pre-war to war and to baby-boom cohort (p<.001). Other differences across cohorts were observed only in women: the proportion of women who never or rarely engaged in sports decreased from 52.9% in the pre-war cohort to around 43% in subsequent cohorts (p<.001), while the proportion of women who had never smoked was higher in the pre-war cohort (56.1%) than in the war and the baby-boom cohorts (49.8% and 46.8%, respectively, p<.001). Overall, these results show some positive changes in older persons' health behaviors over time. Nevertheless, considerable room remains for improving lifestyles through public health interventions.

Is Fear of Falling Associated With Incident Disability? A Prospective Analysis in Young-Old Community-Dwelling Adults.

OBJECTIVES: Fear of falling (FOF) is common in older people and is related to negative outcomes. This study aimed to investigate whether 2 different instruments, the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR), were associated with incident disability at 3 years. DESIGN: Prospective observational study. SETTING AND PARTICIPANTS: Participants (n = 1219, 57.4% women) were disability-free community-dwelling persons enrolled in the Lausanne cohort 65+, aged 66 to 71 years, in 2005. MEASURES: Baseline covariates included demographic, cognitive, affective, and health status. Basic activities of daily living (BADL) assessment was recorded annually from a self-administered questionnaire. Disability outcome was defined as reporting difficulty or help needed in ≥1 of 5 BADL in ≥2 consecutive years, or being institutionalized during follow-up. RESULTS: At 3 years, disability was reported by 77 participants (6.3%). Reporting the highest level of fear at FES-I [adjusted odds ratio (aOR) 5.14, 95% confidence interval (CI) 1.82-14.55, P = .002] or "FOF with activity restriction" with SQ-FAR (aOR 3.23, 95% CI 1.29-8.08, P = .012) were both associated with increased odds of disability even after adjusting for covariates. The FES-I model explained incident disability slightly better than the SQ-FAR one [Bayesian information criterion (BIC) values of 466.70 and 469.43, respectively]. CONCLUSIONS AND IMPLICATIONS: High FOF and related activity restriction, assessed with FES-I and SQ-FAR, are associated with incident disability in young-old community-dwelling people. The SQ-FAR is suitable as a screening tool to proactively detect a potentially reversible risk factor for disability. Using the FES-I may serve additional clinical purposes, such as FOF characterization and management.

Blood pressure control and complex health conditions in older adults: impact of recent hypertension management guidelines.

The American College of Cardiology and the American Heart Association (ACC/AHA) 2017 guidelines for hypertension management lowered blood pressure (BP) thresholds to 130/80 mmHg to define hypertension while the European Society of Cardiology and the European Society of Hypertension (ESC/ESH) 2018 guidelines retained 140/90 mmHg. Both guidelines recommend adapting management for older patients with complex health conditions, without however clear indications on how to adapt. Our aims were to assess the impact of lowering BP thresholds on the prevalence of elevated BP and BP control, as well as the proportion of participants with a complex health condition across these BP categories. We used data from 3210 participants in the Lausanne cohort Lc65+ aged between 67 and 80 years. Hypertension diagnosis and antihypertensive medication use were self-reported. BP was measured three times at one visit. Some 51% of participants reported having hypertension and 44% reported taking antihypertensive medication. Compared with ESC/ESH thresholds, the prevalence of measured elevated BP was 24% percentage points higher and BP control was 24% percentage points lower using ACC/AHA thresholds. About one out of two participants with elevated BP and four out of five participants with uncontrolled BP had a complex health condition, i.e., frailty, multimorbidity, or polypharmacy. To comply with ACC/AHA guidelines, considerable effort would be required to reach BP control. This is a serious challenge because a large share of hypertensive older adults has complex health conditions, a type of patients for whom there is no strong evidence on how to manage hypertension.

Validity of the older people quality of life-7 domains (OQoL-7) scale.

BACKGROUND: The Older people Quality of Life-7 domains (OQoL-7) is a 28-item multidimensional questionnaire developed to measure community-dwelling older people's QoL. The OQoL-7 assesses both importance of and satisfaction in seven QoL domains (Material resources; Close entourage; Social and cultural life; Esteem and recognition; Health and mobility; Feeling of safety; and Autonomy). This study aimed to investigate concurrent and construct validity of the OQoL-7. A secondary aim was to compare different methods of weighting participants' ratings of satisfaction according to their individual ratings of importance, as compared to the OQoL-7 total score (unweighted). METHODS: Data came from the first and second samples of the Lausanne cohort 65+ study, assessed at the same age of 72-77 years in 2011 (N = 1117) and 2016 (N = 1091), respectively. To assess concurrent validity, the OQoL-7 was compared to other measures of the same concept (single QoL item) or related concepts (self-rated health, SF-12). Construct validity was tested by comparing subscores in the seven QoL domains in the presence and absence of two stressful events during the preceding year (financial difficulties and relationship difficulties). The effect of importance weighting was assessed using moderated regression analysis. RESULTS: The OQoL-7 total score was significantly associated with the single QoL item (Spearman's rho 0.46), self-rated health (Spearman's rho 0.34), SF-12 physical (Spearman's rho 0.22) and mental (Spearman's rho 0.28) component scores. Large differences (Cohen's d > 0.8) were observed in the presence or absence of stressful events in the expected QoL domains: "Material resources" in the presence or absence of "Financial difficulties" (Cohen's d 1.34), and "Close entourage" in the presence or absence of "Relationship difficulties" (Cohen's d 0.84). Importance weighting resulted in a very small improvement in the prediction of the single QoL item (ΔR2 0.018). All results were highly consistent across 2011 and 2016 samples. CONCLUSIONS: The OQoL-7 showed adequate concurrent and construct validity in two samples of older people. In future studies, the decision to use weighted or unweighted scores will depend on the priority given to either optimizing the prediction of QoL or limiting the burden on respondents and the amount of missing data.

Factors associated with going outdoors frequently: a cross-sectional study among Swiss community-dwelling older adults.

OBJECTIVE: This study examines potential risk and protective factors associated with going outdoors frequently among older persons, and whether these factors vary according to physical limitations. DESIGN: Cross-sectional analysis. SETTING AND PARTICIPANTS: Community-dwelling participants of the Lausanne cohort Lc65+ in 2016, aged 68-82 years (n=3419). METHODS: Associations between going outdoors frequently and physical limitations, sociodemographic, health, psychological and social variables were examined using logistic regression models. Subgroup analyses were performed according to the severity of physical limitations. MAIN OUTCOME MEASURES: 'Going outdoors frequently' was defined as going out ≥5 days/week and not spending most of the time sitting or lying down. RESULTS: Three in four (73.9%) participants reported going outdoors frequently. Limitations in climbing stairs (adjusted OR (AdjOR) 0.61, 95% CI 0.47 to 0.80) and walking (AdjOR 0.24, 95% CI 0.18 to 0.31), as well as depressive symptoms (AdjOR 0.58, 95% CI 0.47 to 0.70), dyspnoea (AdjOR 0.60, 95% CI 0.48 to 0.75), age (AdjORolder age group 0.73, 95% CI 0.59 to 0.92) and fear of falling (AdjOR 0.75, 95% CI 0.62 to 0.91) reduced the odds of going outdoors frequently. In contrast, living alone (AdjOR 1.30, 95% CI 1.08 to 1.56), reporting a dense (AdjOR 1.57, 95% CI 1.26 to 1.96) and a high-quality (AdjOR 1.28, 95% CI 1.06 to 1.53) social network increased the odds of going outdoors frequently. Among participants with severe limitations, 44.6% still went outdoors frequently. Among this subgroup, a new emotional relationship (AdjOR 2.52, 95% CI 1.18 to 5.38) was associated with going outdoors, whereas cognitive complaints (AdjOR 0.66, 95% CI 0.47 to 0.93), urinary incontinence (AdjOR 0.67, 95% CI 0.46 to 0.97), dyspnea (AdjOR:0.67, 95%CI:0.48-0.93), and depressive symptoms (AdjOR 0.67, 95% CI 0.48 to 0.93) lowered the odds of going outdoors. CONCLUSION: Physical limitations are associated with decreased odds of going outdoors frequently. However, social characteristics appear to mitigate this association, even among older persons with severe limitations. Further studies are needed to determine causality and help guide interventions to promote going outdoors as an important component of active ageing.

Measuring Slowness in Old Age: Times to Perform Moberg Picking-Up and Walking Speed Tests.

OBJECTIVES: Slowness is a marker of frailty captured by the Fried phenotype by a walking speed test which, for health or logistical reasons, is sometimes difficult to perform. The Moberg picking-up test (MPUT) is another timed functional test. It measures hand motor activity and might represent an alternative to assess slowness when the walking speed cannot be evaluated. This study aimed to evaluate the relationship between MPUT and walking speed. DESIGN: Cross-sectional. SETTING AND PARTICIPANTS: In total, 2748 individuals aged 66 to 83 years who participated in the latest examination (2015-2017) of the population-based Lausanne cohort 65+ and completed both tests. METHODS: Walking speed (time to walk 20 meters at usual pace) and MPUT (time to pick up 12 objects) were compared using scatter graphs. Multivariate regression models further investigated the relationship between MPUT and walking times with adjustment for height, grip strength, body mass index, and Mini-Mental State Examination. All analyses were stratified by sex. RESULTS: MPUT and walking times were moderately, positively correlated in men (r = 0.38, P < .001) and in women (r = 0.38, P < .001). Higher grip strength and Mini-Mental State Examination performances were correlated to shorter MPUT and walking times. Men and women slower at the MPUT were also significantly slower at the walking speed test when adjusting for height (P < .001) as well as in fully adjusted models (P < .001). CONCLUSIONS AND IMPLICATIONS: These preliminary results point to a positive association between MPUT and walking speed independent of muscle strength and cognition. Further research is needed to investigate the capacity of MPUT to predict adverse health outcomes before considering this test as an alternative measure of slowness in the assessment of frailty.

Sleep characteristics and self-rated health in older persons.

PURPOSE: It remains unclear, how much older persons' sleep problems are due to age-related changes in sleep architecture and pattern, or whether they are a consequence of health problems. This work aimed to examine the association between sleep characteristics and self-rated health, taking into account potential confounders. METHODS: Data about sleep, including sleep efficiency (ratio of sleep duration to the amount of time spent in bed, considered as good if > 85%), as well as health-rated characteristics were self-reported by community-dwelling persons enrolled in the Lausanne cohort 65+ study (n = 2712, age 66-75 years). Participants' subjective health was categorized as good versus poor. The cross-sectional association between good self-rated health and sleep characteristics was examined in bivariate and multivariate analysis. RESULTS: The majority of participants (68.4%) rated their health as good. Compared to the participants with poor-rated health, they more often reported a good sleep efficiency (59.5% vs 45.0%, p < 0.001) and less often reported napping (41.6% vs 54.0%, p < 0.001) as well as using sleep medication (12.7% vs 31.8%, p < 0.001). After adjustment for comorbidity, depressive symptoms and cognitive difficulties, a positive association persisted between good sleep efficiency and good self-rated health (adjOR: 1.35, 95% CI 1.10-1.66). Regular napping remained negatively associated to feel healthy (adjOR: 0.65, 95% CI 0.53-0.79). CONCLUSION: Sleep efficiency is positively associated with subjective health, whereas napping and use of sleep medication are negatively associated to rating own health as good. These associations need to be further investigated in longitudinal analyses to better understand causality.

A Single Question as a Screening Tool to Assess Fear of Falling in Young-Old Community-Dwelling Persons.

OBJECTIVES: Fear of falling (FOF) is common in older persons and related to negative outcomes. This study aimed to investigate the relationship between 2 FOF measures: the Falls Efficacy Scale-International (FES-I) and the single question on FOF and activity restriction (SQ-FAR). Factors associated with disagreement between the 2 measures were further examined. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Participants (N = 1359) were community-dwelling persons aged 65 to 70 years who were enrolled in the Lausanne cohort 65+. METHODS: Data included demographic, functional, cognitive, affective, and health status. FOF was measured with FES-I and the 3-level SQ-FAR (no FOF, FOF without activity restriction (AR, FOF with AR). FES-I concern about falling was categorized as low (score 16-19), moderate (score 20-27), and high (score 28-64). RESULTS: Weighted agreement between the FES-I and the SQ-FAR was 87.8% (Kappa = 0.57). Using the FES-I as gold standard, the performance of SQ-FAR was good (specificity 86%; sensitivity 74%, negative predicting value 89%, positive predicting value 69%). Among participants with moderate/high FOF according to FES-I, male sex (P = .011) and the absence of previous falls (P < .001) were associated with disagreement between the 2 tools. Among participants with low FOF, female sex (P = .005), falls history (P < .001), and pre-frailty/frailty status (P = .050) were associated with disagreement. CONCLUSIONS AND IMPLICATIONS: The SQ-FAR has a moderate agreement with FES-I and might be used as a screening tool. The results also may help design a step-by-step strategy to evaluate and address FOF in the clinical setting.

Use of healthcare services and assistive devices among centenarians: results of the cross-sectional, international5-COOP study.

OBJECTIVES: To measure the use of healthcare services and assistive devices by centenarians in five countries. DESIGN: Cross-sectional study using a survey questionnaire. SETTING: Community-dwelling and institutionalised centenarians living in Japan, France, Switzerland, Sweden and Denmark. PARTICIPANTS: 1253 participants aged 100 or in their 100th year of life, of whom 1004 (80.1%) were female and 596 (47.6%) lived in institutions. MAIN OUTCOME MEASURES: Recent use of medical visits, nursing care at home, home-delivered meals, acute care hospital stays overnight, professional assessments such as sight tests, mobility aids and other assistive devices. A set of national healthcare system indicators was collected to help interpret differences between countries. RESULTS: There was considerable variability in the healthcare services and assistive devices used by centenarians depending on their country and whether they were community-dwelling or institutionalised. In contrast to the relatively homogeneous rates of hospitalisation in the past year (around 20%), community-dwelling centenarians reported widely ranging rates of medical visits in the past 3 months (at least one visit, from 32.2% in Japan to 86.6% in France). The proportion of community-dwellers using a mobility device to get around indoors (either a walking aid or a wheelchair) ranged from 48.3% in Japan to 79.2% in Sweden. Participants living in institutions and reporting the use of a mobility device ranged from 78.6% in Japan to 98.2% in Denmark. CONCLUSIONS: Our findings suggest major differences in care received by centenarians across countries. Some may result from the characteristics of national healthcare systems, especially types of healthcare insurance coverage and the amounts of specific resources available. However, unexplored factors also seem to be at stake and may be partly related to personal health and cultural differences.

Impact of urine and mixed incontinence on long-term care preference: a vignette-survey study of community-dwelling older adults.

BACKGROUND: In view of population aging, a better knowledge of factors influencing the type of long-term care (LTC) among older adults is necessary. Previous studies reported a close relationship between incontinence and institutionalization, but little is known on opinions of older citizens regarding the most appropriate place of care. This study aimed at evaluating the impact of urine and/or fecal incontinence on preferences of community-dwelling older citizens. METHODS: We derived data from the Lausanne cohort 65+, a population-based study of individuals aged from 68 to 82 years. A total of 2974 community-dwelling persons were interviewed in 2017 on the most appropriate place of LTC delivery for three vignettes displaying a fixed level of disability with varying degrees of incontinence (none, urinary, urinary and fecal). Multinomial logistic regression analyses explored the effect of respondents' characteristics on their opinion according to Andersen's model. RESULTS: The level of incontinence described in vignettes strongly determined the likelihood of considering institutional care as most appropriate. Respondents' characteristics such as age, gender, educational level, being a caregiver, knowledge of shelter housing or feeling supported by family influenced LTC choices. Self-reported incontinence and other indicators of respondents' need, however, had no significant independent effect. CONCLUSION: Among older community-dwelling citizens, urinary and fecal incontinence play a decisive role in the perception of a need for institutionalization. Prevention and early initiation of support for sufferers may be a key to prevent this need and ensure familiar surrounding as long as possible.
