Accumulation of sensory difficulties predicts fear of falling in older women

Association of Single and Dual Sensory Impairment with Falls among Medicare Beneficiaries

Objective: The purpose of this study was to determine if dual sensory impairment (DSI) is associated with falls and fear of falling among older adults. Methods: Using data from the 2019 Medicare Current Beneficiary Survey (MCBS), we studied the cross-sectional association of self-reported hearing/vision impairment with self-reported history/number of falls over the past year, fear of falling (scale 1-6), and a fall requiring medical help using weighted multivariable regressions adjusted for demographic and clinical covariates. Results: Among 11,089 Medicare beneficiaries (mean age = 74, 55% female, 9% Black), DSI is associated with increased prevalence (prevalence ratio = 1.45 [1.28-1.65]) and incidence (incidence ratio = 2.21 [1.79-2.75]) rate of falls, and greater odds of a higher fear of falling score (odds ratio = 1.38 [1.08-1.77]). Discussion: DSI is associated with falls among older adults. Consideration of DSI as a marker to initiate fall prevention programs and inclusion of sensory interventions in these programs may be valuable.

The global prevalence of and risk factors for fear of falling among older adults: a systematic review and meta-analysis

BACKGROUND

As a common psychological problem among older adults, fear of falling was found to have a wide range prevalence in different studies. However, the global prevalence of it was unknown and a lack of the large sample confirmed its risk factors.

OBJECTIVES

To report the global prevalence of fear of falling and to explore its risk factors among older adults for further developing precise interventions to systematically manage FOF.

DESIGN

A systematic review and meta-analysis was conducted by PRISMA guidelines.

METHODS

Searches were conducted in PubMed, Web of Science, EMBASE, the Cochrane Library and the manual search in August 20, 2022, updated to September 2, 2023. Observational studies published in English were included and two researchers independently screened and extracted the data. Fixed or random effects mode was used to estimate the pooled prevalence of and risk factors for fear of falling. Heterogeneity resources were analyzed by subgroup and sensitivity analysis. Publication bias was assessed through funnel plots, Egger's test and Begg's test.

RESULTS

A total of the 153 studies with 200,033 participants from 38 countries worldwide were identified. The global prevalence of fear of falling was 49.60%, ranging from 6.96-90.34%. Subgroup analysis found the estimates pooled prevalence of it was higher in developing countries (53.40%) than in developed countries (46.7%), and higher in patients (52.20%) than in community residents (48.40%). In addition, twenty-eight risk factors were found a significant associations with fear of falling, mainly including demographic characteristics, physical function, chronic diseases and mental problems.

CONCLUSION

The global prevalence of FOF was high, especially in developing countries and in patients. Demographic characteristics, Physical function, chronic diseases and mental problems were a significant association with FOF. Policy-makers, health care providers and government officials should comprehensively evaluate these risk factors and formulate precise intervention measures to reduce FOF.

TRIAL REGISTRATION

The study was registered in the International Database of Prospectively Registered Systematic Reviews (PROSPERO): CRD42022358031.

Concentrating to avoid falling: interaction between peripheral sensory and central attentional demands during a postural stability limit task in sedentary seniors

Evidence suggests falls and postural instabilities among seniors are attributed to a decline in both the processing of afferent signals (e.g., proprioceptive, vestibular) and attentional resources. We investigated the interaction between the non-visual and attentional demands of postural control in sedentary seniors. Old and young adults performed a postural stability limit task involving a maximal voluntary leaning movement with and without vision as well as a cognitive-attentional subtraction task. These tasks were performed alone (single-task) or simultaneously (dual-task) to vary the sensory-attentional demands. The functional limits of stability were quantified as the maximum center of pressure excursion during voluntary leaning. Seniors showed significantly smaller limits of postural stability compared to young adults in all sensory-attentional conditions. However, surprisingly, both groups of subjects reduced their stability limits by a similar amount when vision was removed. Furthermore, they similarly decreased their anterior-posterior stability limits when concurrently performing the postural and the cognitive-attentional tasks with vision. The overall average cognitive performance of young adults was higher than seniors and was only slightly affected during dual-tasking. In contrast, older adults markedly degraded their cognitive performance from the single- to the dual-task situations, especially when vision was unavailable. Thus, their dual-task costs were higher than those of young adults and increased in the eyes-closed condition, when postural control relied more heavily on non-visual sensory signals. Our findings provide the first evidence that as posture approaches its stability limits, sedentary seniors allot increasingly large cognitive attentional resources to process critical sensory inputs.

Subjective vision and hearing impairment and falls among community-dwelling adults: a prospective study in the Survey of Health, Ageing and Retirement in Europe (SHARE)

PURPOSE

To investigate the association between vision and hearing impairment and falls in community-dwelling adults aged ≥ 50 years.

METHODS

This is a prospective study on 50,986 participants assessed in Waves 6 and 7 of the Survey of Health, Ageing and Retirement in Europe. At baseline, we recorded socio-demographic data, clinical factors and self-reported vision and hearing impairment. We classified participants as having good vision and hearing, impaired vision, impaired hearing or impaired vision and hearing. We recorded falls in the six months prior to the baseline and 2-year follow-up interviews. The cross-sectional and longitudinal associations between vision and hearing impairment categories and falls were analysed by binary logistic regression models; odds ratios (OR) and 95% confidence intervals (CI) were calculated. All analyses were adjusted for socio-demographic and clinical factors.

RESULTS

Mean age was 67.1 years (range 50-102). At baseline, participants with impaired vision, impaired hearing, and impaired vision and hearing had an increased falls risk (OR (95% CI)) of 1.34 (1.22-1.49), 1.34 (1.20-1.50) and 1.67 (1.50-1.87), respectively, compared to those with good vision and hearing (all p < 0.001). At follow-up, participants with impaired vision, without or with impaired hearing, had an increased falls risk of 1.19 (1.08-1.31) and 1.33 (1.20-1.49), respectively, compared to those with good vision and hearing (both p < 0.001); hearing impairment was longitudinally associated with falls in middle-aged women.

CONCLUSION

Vision impairment was cross-sectionally and longitudinally associated with an increased falls risk. This risk was highest in adults with dual sensory impairment.

The Older Finnish Twin Cohort - 45 Years of Follow-up

The older Finnish Twin Cohort (FTC) was established in 1974. The baseline survey was in 1975, with two follow-up health surveys in 1981 and 1990. The fourth wave of assessments was done in three parts, with a questionnaire study of twins born during 1945-1957 in 2011-2012, while older twins were interviewed and screened for dementia in two time periods, between 1999 and 2007 for twins born before 1938 and between 2013 and 2017 for twins born in 1938-1944. The content of these wave 4 assessments is described and some initial results are described. In addition, we have invited twin-pairs, based on response to the cohortwide surveys, to participate in detailed in-person studies; these are described briefly together with key results. We also review other projects based on the older FTC and provide information on the biobanking of biosamples and related phenotypes.

The meaning of confidence for older people living with frailty: a qualitative systematic review

BACKGROUND

In many countries, the oldest old (those aged 85 years and older) are now the fastest growing proportion of the total population. This oldest population will increasingly be living with the clinical condition of frailty. Frailty syndromes negatively impact on the person as they do the healthcare systems supporting them. Within healthcare literature "loss of confidence" is occasionally connected to older people living with frailty, but ambiguously described. Understanding the concept of confidence within the context of frailty could inform interventions to meet this growing challenge.

OBJECTIVES

The objective of this systematic review was to explore the meaning of confidence from the perspective of older people living with frailty through synthesis of qualitative evidence to inform healthcare practice, research and policy.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Studies that included frail adults, aged over 60 years, experiencing acute hospital and or post-acute care in the last 12 months.

PHENOMENA OF INTEREST

The concept of "confidence" and its impact on the physical health and mental well-being of older people living with frailty.

CONTEXT

Studies that reported on the older person's descriptions, understanding and meaning of confidence in relation to their frailty or recent healthcare experiences.

TYPES OF STUDIES

Studies of qualitative design and method.

SEARCH STRATEGY

A three step search strategy was used. The search strategy explored published studies and gray literature. Publications in English from the last 20 years were considered for inclusion.

METHODOLOGICAL QUALITY

All included articles were assessed by two independent reviewers using the Joanna Briggs Institute Qualitative Assessment Review Instrument (JBI-QARI).

DATA EXTRACTION

Data were extracted from included studies using the data extraction tools developed by the Joanna Briggs Institute.

DATA SYNTHESIS

Qualitative research findings were collated using a meta-aggregative approach and JBI-QARI software.

RESULTS

Synthesized findings of this review were drawn from just four research studies that met the inclusion criteria. Only six findings contributed to the creation of three categories. These informed a single synthesized finding: Vulnerability, described as a fragile state of well-being that is exposed to the conflicting tensions between physical, emotional and social factors. These tensions have the capability to enhance or erode this state.

CONCLUSIONS

Assertions that an understanding of the concept confidence has been reached cannot be made. The review data offer limited insight into the concept of confidence being described by the cohort of older people living with frailty.

Prospective Study on the Impact of Fear of Falling on Functional Decline among Community Dwelling Elderly Women

Fear of falling (FOF) is expected to have effects on functional decline in the elderly. In this study, we examined over 2 years the effect of change in FOF on functional decline in community dwelling elderly. We conducted a secondary analysis using data from elderly women, 70 years of age and older, who participated in the Korean Longitudinal Study of Aging (KLoSA). Participants were divided into four categories according to change in FOF between the 2010 and 2012 surveys. Multiple logistic regression analysis was conducted regarding the effects of changes in FOF on functional decline after controlling for variables as known risk factors for functional decline. Rates of functional decline were highest in the “consistently having FOF” group, whereas they were lowest in the “consistently no FOF” group in both 2010 and 2012. Characteristics independently associated with functional decline were change in FOF, depressive symptoms, low frequency of meeting friends, and fear-induced activity avoidance. Longer exposure to FOF was associated with an increased risk of functional decline. FOF is an important health problem that deserves attention in its own right. Public health approaches for elderly persons should address early detection, prevention, and intervention programs for FOF.

The Complex Association Between Fear of Falling and Mobility Limitation in Relation to Late-Life Falls: A SHARE-Based Analysis

OBJECTIVE

This study examines fear of falling (FOF) in relation to falls in light of mobility limitation.

METHOD

Data on community-dwelling older Europeans, aged 65+, were drawn from two consecutive waves of the Survey of Health, Ageing and Retirement in Europe (SHARE). The analysis regressed fall status in 2013 on reported FOF 2 to 3 years earlier, controlling for previous falls.

RESULTS

FOF predicted subsequent falls when mobility limitation was low to moderate. However, the effect of FOF on fall probability was reversed when mobility limitation was high.

DISCUSSION

The analysis underscores a complex association between FOF and mobility limitation in relation to late-life falls. People who are worried about falling tend to fall more. Those having high mobility limitation but lacking FOF are also more likely to fall. In cases of considerable mobility limitation, FOF may act as a protective buffer. The less worried in this group, however, may be subject to greater falling, and thus require greater attention.

[Rationale, design and methodology of physical attributes identification of the fear of falling syndrome (FISTAC study)]

INTRODUCTION

The aim of this study was to identify the physical determining factors of the Fear of Falling Syndrome (FoF) in older adults with a history of falls.

METHODS

An observational study was conducted on 183 subjects older than 64 years with a fall in the previous year, with data collected from the geriatrics outpatient clinic of the Complejo Hospitalario Universitario from Albacete, Spain. Sociodemographic and anthropometric data, as well as comorbidity, drugs usually taken, functional status, physical function, frailty, cognitive and affective status were collected. Muscle mass was measured using bioimpedancy meter (BIA), and densitometry (DXA), strength with digital hand-held JAMAR dynamometer and with a Leg-press machine, muscle potency with a T-Force instrument, gait variability with the Gait-Rite instrument, and postural stability with the Neurocom Balance Master posturograph were also determined. An analysis was performed to determine if the FoF is associated with physical impairments adjusted for the study covariates.

RESULTS

The study included 140 subjects with FoF, and 43 without it. The mean age was 78.4 years, and 147 were women. Posturography could be measured in 182 participants, DXA in 117, BIA in 165, and muscle potency in 146. FoF was associated with female sex, frailty, depressed mood, social risk, muscle strength and power, physical function, number of drugs used, and orthostatic hypotension in the overall sample. After adjusting for sex, only frailty, depressed mood, and number of drugs remained associated.

CONCLUSIONS

Rationale, design, and methods of the FISTAC study are presented.

Do Associations Between Perceived Environmental and Individual Characteristics and Walking Limitations Depend on Lower Extremity Performance Level?

Objective: The aim of this study was to analyze whether the associations between perceived environmental and individual characteristics and perceived walking limitations in older people differ between those with intact and those with poorer lower extremity performance. Method: Persons aged 75 to 90 ( N = 834) participated in interviews and performance tests in their homes. Standard questionnaires were used to obtain walking difficulties; environmental barriers to and, facilitators of, mobility; and perceived individual hindrances to outdoor mobility. Lower extremity performance was tested using Short Physical Performance Battery (SPPB). Results: Among those with poorer lower extremity performance, the likelihood for advanced walking limitations was, in particular, related to perceived poor safety in the environment, and among those with intact performance to perceived social issues, such as lack of company, as well as to long distances. Discussion: The environmental correlates of walking limitations seem to depend on the level of lower extremity performance.

Characteristics Associated With Fear of Falling and Activity Restriction in South Korean Older Adults

Objectives: The purpose of this study was to identify the characteristics associated with fear-induced activity restriction and determine those that distinguish older adults with fear-induced activity restriction from those with fear of falling alone. Method: Data taken from the survey of the Korean Longitudinal Study of Aging in 2010 were analyzed. Multiple logistic regression analysis was used to assess factors associated with fear of falling and fear-induced activity restriction. Results: A total of 22.5% of the participants reported no fear of falling, 48.6% reported fear of falling alone, and 28.9% reported fear-induced activity restriction. Characteristics independently associated with fear-induced activity restriction were low socioeconomic status, cognitive impairment, difficulty with activities of daily living, and a history of injurious falls. Discussion: The differences between older adults with fear-induced activity restriction and those with fear of falling alone may guide refinement of intervention and preventive programs.
