Abstract
Frailty and Biological Age are two closely related concepts; however, frailty is a multisystem geriatric syndrome that applies to elderly subjects, whereas biological age is a gerontologic way to describe the rate of aging of each individual, which can be used from the beginning of the aging process, in adulthood. If frailty reaches less consensus on the definition, it is a term much more widely used than this of biological age, which shows a clearer definition but is scarcely employed in social and medical fields. In this review, we suggest that this Biological Age is the best to describe how we are aging and determine our longevity, and several examples support our proposal.

Abstract
OBJECTIVE Olfactory dysfunction is a "canary in the coalmine" for aging conditions. We evaluated olfactory dysfunction as a biomarker of early frailty in older adults living in the United States. STUDY DESIGN Prospective, longitudinal, nationally representative study. SETTING National Social Life, Health and Aging Project (NSHAP). METHODS We examined data from 1061 community-dwelling older US adults. Odor identification (5-item Sniffin' Stick) and frailty scores were measured at baseline and 5-year follow-up. Multivariate logistic regressions evaluated the association between olfactory dysfunction and frailty at baseline in cross-section and over time in the transition from robust to prefrail to frail, adjusting for confounding factors measured at baseline. RESULTS Older US adults who were anosmic at baseline were more likely to be frail 5 years later compared to normosmic peers (odds ratio [OR]: 3.83, 95% confidence interval [CI]: 1.10-13.31, P = .035). Examining changes in frailty stage over time, we found that anosmics were more likely to transition from prefrail to frail over 5 years (OR: 3.25, 95% CI: 1.31-8.08, P = .011). Interestingly, hyposmics did not show a similar trajectory toward frailty (P > .05). In contrast, olfactory dysfunction was not associated with frailty in cross-section (OR: 0.90, 95% CI: 0.43-1.89, P = .787, hyposmia; OR: 0.72, 95% CI: 0.15-3.35, P = .673, anosmia). CONCLUSION Older US adults with anosmia face higher odds of becoming frail over 5 years, especially those in the prefrail stage. Olfactory dysfunction may serve as a surrogate marker for early-stage neurodegenerative diseases, which are strong contributors to frailty.

Abstract
We examined the relationship between vision impairment (VI) and new-onset frailty among non-frail Mexican American older adults (≥70 years) at baseline and determined the differential impact of VI on each frailty criteria. Data were from an 18-year prospective cohort from the Hispanic Established Population for the Epidemiologic Study of the Elderly (1998/1999, N = 1072 to 2016, N = 175). Frailty was defined as ≥3 criteria: unintentional weight loss of >10 pounds, weakness, exhaustion, low physical activity, and slowness. VI was defined as difficulty in recognizing a friend at arm's length's away, across the room, or across the street. We found that participants with VI (near or distant) and distant VI had greater odds of frailty (near or distant VI, OR = 1.89, 95% CI = 1.30-2.73 and distant VI, OR = 1.95, 95% CI = 1.34-2.86, respectively) after controlling for covariates over time. Early screening (optimal management) of VI may prevent or delay onset of frailty among older Mexican Americans.

Abstract
Introduction Vision impairment (VI) may further exacerbate older adults' vulnerability to experiencing food insecurity and may be a unique and important target for policies addressing access to nutritional food. The purpose of this study is to determine the association of VI in older adults with food insecurity. Methods This is a cross-sectional analysis of round 11 (2021) of the National Health and Aging Trends Study (NHATS), a nationally representative survey of U.S. Medicare beneficiaries ages 65 and older. Participants include 2,815 older adults with complete data on at least one objective measure of vision (distance, near or contrast sensitivity) and food insecurity. Food insecurity was assessed using a previously developed indicator of food insecurity in NHATS. VI was defined as binocular visual acuity (VA) worse than 0.3 logMAR (Snellen equivalent 20/40) at distance or its near equivalent, or contrast sensitivity (CS) worse than 1.55 logUnits. Continuous VI measures included distance and near VA (per 0.1 logMAR), and CS (per 0.1 logCS). Results Participants were majority White (82%) and female (55%), and 3% had food insecurity. Older adults with any VI had a greater prevalence of food insecurity than adults without VI (5.0% vs. 2.0%, p < 0.05). In fully adjusted regression analyses, individuals with any VI experienced double the odds of food insecurity than individuals without VI (OR: 2.1, 95% CI: 1.2-3.6). Distance VI (measured continuously) was associated with 1.2 times the odds of food insecurity (OR = 1.2; 95% CI: 1.0-1.3, per 0.1 logMAR). All other vision measures trended towards higher odds of food insecurity, though not statistically significant. Discussion Older adults with VI experience higher rates of food insecurity than their peers. Interventions to improve food security should be targeted towards addressing the specific barriers faced by visually impaired older adults.

Abstract
AIM This study aimed to investigate the association between intrinsic capacity (IC) and frailty in community-dwelling older adults. Specifically, we examined the utility of the World Health Organization's Integrated Care for Older People Step 1 screen for identifying frail older persons in the community. METHODS This is a cross-sectional analysis of a community frailty screening initiative. IC loss was ascertained using the World Health Organization's Integrated Care for Older People Step 1 questions. The Clinical Frailty Scale was used to categorize participants as robust (Clinical Frailty Scale S1-3) or frail (Clinical Frailty Scale ≥4). Logistic regression was used to analyze the association of individual and cumulative IC losses with frailty, adjusting for confounders. Additionally, the diagnostic performance of using cumulative IC losses to identify frailty was assessed. RESULTS This study included 1164 participants (28.2% frail). Loss in locomotion (adjusted odds ratio [AOR] 1.47, 95% CI 1.07-2.02), vitality (AOR 1.58, 95% CI 1.04-2.39), sensory (AOR 1.99, 95% CI 1.51-2.64) and psychological capacities (AOR 1.92, 95% CI 1.45-2.56) were significantly associated with frailty. Loss in more than three IC domains was associated with frailty. Using loss in at least three ICs identifies frailty, with sensitivity of 38.6%, specificity of 83.5% and positive predictive value of 47.4%. Using loss in at least four ICs improved specificity to 96.9%, and is associated with the highest positive predictive value of 57.6% and highest positive likelihood ratio of 3.55 for frailty among all cut-off values. The area under the receiver operating characteristic curve was 0.64 (95% CI 0.61-0.68). CONCLUSIONS IC loss as identified through World Health Organization's Integrated Care for Older People Step 1 is associated with frailty community-dwelling older adults.

Abstract
PURPOSE Older adults with cardiovascular diseases (CVD) are prone to falls. This study aimed to analyze the combined effect of falling difficulty and CVD on the risk of all-cause- and CVD mortality in older adults. METHODS In this retrospective cohort study, people aged ≥60 years with information on falling difficulty and CVD from the 1999-2004 National Health and Nutrition Examination Survey (NHANES) were selected. Multivariable Cox proportional hazards regression model was used to assess the associations of falling difficulty and CVD with all-cause- and CVD mortality. RESULTS A total of 1409 participants were included, of whom 868 (58.1%) participants died, and 237 (15.0%) died of CVD. The mean age of participants was 72.1 (0.3) years and 825 (64.7%) were female. Older adults with falling difficulty or CVD were associated with an increased risk of all-cause- and CVD mortality. Older adults in the no falling difficulty & CVD group [hazard ratio (HR) = 1.45, 95% confidence interval (CI) 1.19-1.78], the falling difficulty & no CVD group (HR = 1.45, 95%CI 1.12-1.89), and the falling difficulty & CVD group (HR = 2.13, 95%CI 1.77-2.56) were related to a higher risk of all-cause mortality compared to those in the no falling difficulty & no CVD group. The combined effect of falling difficulty and CVD was positively correlated with the risk of all-cause mortality (HR = 1.26, 95%CI: 1.18-1.34; P-trend <0.001) and CVD mortality (HR = 1.36, 95%CI: 1.18-1.56; P-trend <0.001). CONCLUSION The combined effect of falling difficulty and CVD was positively associated with the risk of all-cause- and CVD mortality in older adults.

Abstract
Background Decline in intrinsic capacity (IC) has been shown to accelerate progression to disability. The study aims to explore association of IC composite score with functional ability, sarcopenia and systemic inflammation in pre-frail older adults. Methods Cross-sectional study of pre-frail older adults ≥60 years old recruited from the community and primary care centers. Composite scores of four domains of IC were measured: locomotion, vitality, cognition and psychological. FRAIL scale was used to define pre-frailty. Muscle mass was measured using the bioelectrical impedance analysis. Systemic inflammation biomarkers [Interleukin-6 (IL-6), Interleukin-10 (IL-10), Tumor Necrosis Factor Alpha (TNF-α), and Growth differentiated factor 15 (GDF-15)] were measured. Participants in the lowest tertile (T1) exhibited greater decline in IC. Results A total of 398 pre-frail older adults were recruited, mean age was 72.7 ± 5.8 years, 60.1% female, education level 7.8 years, and 85.2% were of Chinese ethnicity. A total of 75.1% had decline in locomotion, 40.5% in vitality, 53.2% in cognition and 41.7% in psychological domain. A total of 95% had decline in at least one domain. T1 was significantly associated with ADL impairment (aOR 3.36, 95% CI 1.78-6.32), IADL impairment (aOR 2.37, 95% CI 1.36-4.13), poor perceived health (aOR 0.96, 95% CI 0.95-0.98), fall (aOR 1.63, 95% CI 1.05-2.84), cognitive impairment (aOR 8.21, 95% CI 4.69-14.39), depression (aOR 101.82, 95% CI 33.62-308.37), and sarcopenia (aOR 2.40, 95% CI 1.60-5.45). T1 had significant associations with GDF-15, IL-10, and IL-10 to TNF-α ratio. Conclusion Decline in IC composite score among pre-frail older adults was associated with functional limitation, sarcopenia, and systemic inflammation.

Abstract
BACKGROUND Hearing and vision difficulties are some of the most common deficits experienced by older adults. Having either visual or hearing difficulties increases the risk of comorbidity, disability, and poor quality of life. So far, however, few studies have examined the association between vision and hearing difficulties on life expectancy without activities of daily living (ADL) or instrumental ADL (IADL) limitations (LEWL). METHODS Data came from the English Longitudinal Study of Ageing and the Health and Retirement Study in the United States from 2002 to 2013. The outcome was defined as reporting 2+ limitations with ADL/IADL. Life expectancy was estimated by discrete-time multistate life table models for hearing and vision difficulties separately as well as for combined vision and hearing difficulties by sex and age. RESULTS Thirteen percent of men in England and the United States had ADL/IADL limitations, whereas, for women, it was 16% and 19% in England and the United States. At all ages, either vision or hearing difficulty was associated with shorter LEWL compared to no difficulties. Dual sensory difficulty (vision and hearing) reduced LEWL by up to 12 years in both countries. At the ages of 50 and 60 in England, hearing difficulty was associated with fewer years lived without ADL/IADL limitations than vision difficulty. In contrast, in the United States, vision difficulty led to fewer years lived without ADL/IADL limitations than hearing difficulty. CONCLUSIONS The implementation of strategies to reduce the prevalence and incidence of vision and hearing difficulties has the potential to increase the number of years spent without ADL/IADL limitations.

Abstract
AIMS To test whether vision impairment and major ophthalmic conditions are predictive of frailty. METHODS The analysis included 5321 participants aged 60-95 years at baseline from the China Health and Retirement Longitudinal Study. Participants were enrolled in 2011 and followed up in 2013, and 2015 through a face-to-face interview. Distance/near vision impairment was defined by reporting poor eyesight and reporting excellent, very good, good or fair eyesight was used as the reference. A history of cataract surgery and glaucoma were also self-reported. Frailty was defined as the presence of ≥3 of the five components of the Fried phenotype: weakness, slowness, exhaustion, inactivity and shrinking. RESULTS In the cross-sectional analysis, both near (odds ratio [OR] (95% confidence interval [CI]): 1.62 (1.30 to 2.00)) and distance (1.59 (1.30 to 1.96)) vision impairment was associated with a higher prevalence of frailty independent of confounders. In the longitudinal analysis, the multivariable-adjusted OR (95% CI) for incident frailty associated with glaucoma, distance vision impairment, near vision impairment and vision problem was 3.41 (1.46 to 7.99), 1.59 (1.17 to 2.17), 1.62 (1.17 to 2.23) and 2.11 (1.41 to 3.15), respectively. Vision problem was associated with decreased handgrip strength (β (95% CI): -1.47 (-2.20 to -0.75) kg) during follow-up. Individuals with glaucoma (-0.11 (-0.16 to -0.05) m/s), distance vision impairment (-0.02 (-0.03 to 0.00) m/s) or vision problem (-0.02 (-0.05 to 0.00) m/s) had decreased gait speed compared with the control group. CONCLUSIONS Vision problem, vision impairment and glaucoma are important predictors of frailty in older adults.

Abstract
PURPOSE To describe the association between visual field loss and frailty in a nationally representative cohort of US adults. DESIGN Retrospective cross-sectional study. METHODS The cohort included adults 40 years or older with complete eye examination data from the 2005-2006 and 2007-2008 National Health and Nutrition Examination Surveys (NHANES). Visual field loss (VFL) was determined by frequency doubling technology and a 2-2-1 algorithm. A 36-item deficit accumulation-based frailty index was used to divide subjects into 4 categories of increasing frailty severity. RESULTS Of the 4897 participants, 4402 (93.2%) had no VFL, 301 (4.1%) had unilateral VFL, and 194 (2.73%) had bilateral VFL. Within the sample, 2 subjects197 (53.1%) were categorized as non-frail, 1659 (31.3%) as vulnerable, 732 (11.3%) as mildly frail, and 312 (4.3%) as most frail. In multivariable models adjusted for demographics, visual acuity, and history of cataract surgery, subjects with unilateral VFL had higher adjusted odds of being in a more frail category (adjusted odds ratio [aOR], 2.07; 95% CI, 1.42-3.02) than subjects without VFL. Subjects with bilateral VFL also had higher odds of a more frail category compared to subjects without VFL (aOR, 1.74; 95% CI, 1.20-2.52). CONCLUSIONS In the 2005-2008 NHANES adult population, VFL is associated with higher odds of frailty, independent of central visual acuity loss. Frail individuals may be more susceptible to diseases that can cause VFL, and/or VFL may predispose to frailty. Additional studies are needed to determine the directionality of this relationship and to assess potential interventions.

Abstract
BACKGROUND Sensory impairment has been related to age-associated cognitive decline. While these associations were investigated primarily in the auditory and visual domain, other senses such as touch have rarely been studied. Thus, it remains open whether these results are specific for particular sensory domains, or rather point to a fundamental role of sensory deficits in cognitive decline. METHODS Data from 31 participants with mild cognitive impairment (MCI), 46 participants with frailty, and 23 non-clinical control participants (NCCs) were included. We assessed sensory function using visual acuity and contrast sensitivity, hearing threshold, and mechanical detection threshold. Cognitive function in participants with MCI was assessed using associative memory performance. Group differences on sensory thresholds were tested using analyses of covariance with age, sex, and years of education as covariates. Associations between measures within participants with MCI were evaluated using Spearman correlations. FINDINGS We found a significant difference in mechanical detection threshold between the groups (p < 0.001, η2 = 0.18). Participants with MCI showed significantly reduced tactile sensitivity compared to participants with frailty and NCCs. In participants with MCI, lower associative memory performance was significantly related to reduced tactile sensitivity (rs = 0.39, p = 0.031) and auditory acuity (rs = 0.41, p = 0.022). INTERPRETATION Our results indicate that reduced tactile sensitivity is related to cognitive decline. Prospective studies should investigate the age-related alterations of multimodal sensory processes and their contribution to dementia-related processes.

Abstract
BACKGROUND Loss of sensorimotor stimulation and maladaptive plastic changes of the brain may play a major role in problematic aging phenomena such as frailty. However, it is not clear if interventions specifically targeting neuroplasticity can reverse or slow the development of frailty. OBJECTIVES We compared the effect of a tablet-based neuroplasticity-oriented sensorimotor training (experimental group, EG) and a tablet-based relaxation training (control group, CG) on frailty and sensorimotor brain function. METHODS Interventions consisted of daily 30 min sessions distributed over 90 days. Assessments took place at baseline, after 60 days, and after 90 days. A total of N = 48 frail older adults (EG: n = 24; CG: n = 24) were assigned to the two groups and reassessed after 60 days. Primary outcomes included frailty phenotype (FP) and frailty index (FI). Sensorimotor brain activity was evaluated using functional magnetic resonance imaging and single-pulse transcranial magnetic stimulation. RESULTS After 60 days of training, both groups showed a reduction in the number of FP criteria (p < 0.001) with a trend towards a significant time-by-group interaction (p = 0.058) indicating a stronger reduction of frailty in the EG (p < 0.001) compared to the CG (p = 0.039). In addition, pain was significantly reduced in the EG but not the CG. No significant effects were found for measures of brain function. DISCUSSION We provided initial evidence that a neuroplasticity-oriented sensorimotor training could be beneficial in counteracting frailty as well as chronic pain. Further studies are needed to determine the potentially underlying neuroplastic mechanisms and the influence of plasticity-related biomarkers as well as their clinical significance.

Abstract
INTRODUCTION Cognitive frailty is associated with higher risk of dementia and adverse health outcomes. However, multidimensional factors that influence cognitive frailty transitions are not known. We aimed to investigate risk factors of incident cognitive frailty. METHODS Prospective cohort study participants were community-dwelling adults without dementia and other degenerative disorders and baseline and follow-up, including N = 1,054 participants aged ≥55 free of cognitive frailty at baseline, with complete baseline (March 6, 2009, to June 11, 2013) and follow-up data at 3-5 years later (January 16, 2013, to August 24, 2018). Incident cognitive frailty was defined by one or more criteria of the physical frailty phenotype and <26 of Mini-Mental State Examination (MMSE) score. Potential risk factors assessed at baseline included demographic, socioeconomic, medical, psychological and social factors, and biochemical markers. Data were analyzed using least absolute shrinkage selection operator (LASSO) multivariable logistic regression models. RESULTS A total of 51 (4.8%) participants, including 21 (3.5%) of the cognitively normal and physically robust participants, 20 (4.7%) of the prefrail/frail only, and 10 (45.4%) of cognitively impaired only, transited to cognitive frailty at follow-up. Risk factors for transition to cognitive frailty were having eye problem (OR = 2.6, 95% CI 1.24-5.43) and low HDL cholesterol (OR = 4.1, 95% CI 2.03-8.40), while protective factors for cognitive frailty transition were higher levels of education (OR = 0.3, 95% CI 0.10-0.74) and participation in cognitive stimulating activities (OR = 0.4, 95% CI 0.17-0.82). CONCLUSION Multi-domain modifiable factors especially related to leisure activities predict cognitive frailty transition and may be targeted for prevention of dementia and associated adverse health outcomes.

Abstract
BACKGROUND Age-related eye diseases and cognitive frailty (CF) are both important predictors of adverse health outcomes in older adults, however, little is known about their association. AIMS To demonstrate the association between age-related eye diseases and cognitive frailty in a population of Iranian older adults. METHODS In this cross-sectional, population-based study, we included 1136 individuals (female n = 514) aged 60 years and older (mean 68.8 ± 6.7 years) who participated in the second cycle of the Amirkola Health and Aging Project (AHAP) between 2016 and 2017. Cognitive function and frailty were evaluated based on Mini-Mental State Examination (MMSE) and the FRAIL scale respectively. Cognitive frailty was defined as coexistence of cognitive impairment (CI) and physical frailty (PF), excluding confirmed cases of dementia such as Alzheimer's disease. Cataract, diabetic retinopathy (DR), age-related macular degeneration (AMD), elevated intraocular pressure (IOP ≥ 21 mmHg) and glaucoma suspects (vertical cup to disc ratio (VCDR) ≥ 0.6) were diagnosed based on standardized grading protocols. Associations between eye diseases and cognitive frailty were evaluated through binary logistic regression analysis. RESULTS Overall, CI, PF and CF were observed in 257 (22.6%), 319 (28.1%) and 114 (10.0%) participants respectively. After adjusting for confounders and ophthalmic conditions, individuals with cataract were more likely to have CF (OR 1.66; p-value 0.043), while DR, AMD, elevated IOP and glaucoma suspects (OR 1.32, 1.62, 1.42, 1.36, respectively) were not significantly associated with CF. Furthermore, cataract was significantly associated with CI (OR 1.50; p-value 0.022), but not with frailty (OR 1.18; p-value 0.313). CONCLUSION Older adults with cataract were more likely to have cognitive frailty and cognitive impairment. This association demonstrates the implications of age-related eye diseases beyond ophthalmology and substantiates the need for further research involving cognitive frailty in the context of eye diseases and visual impairment.

Ophthalmology 2023; 130:646-654. [PMID: 36731798 PMCID: PMC10614114 DOI: 10.1016/j.ophtha.2023.01.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 01/10/2023] [Accepted: 01/23/2023] [Indexed: 02/02/2023] Open
Abstract
PURPOSE To determine differences in eye care utilization by frailty levels among Medicare beneficiaries with glaucoma. DESIGN Retrospective cohort study. PARTICIPANTS Medicare fee-for-service beneficiaries over 65 years of age with glaucoma, identified using International Classification of Diseases codes before July 1, 2014. METHODS By using a validated claims-based frailty index (range, 0-1), beneficiaries were classified as nonfrail/prefrail (0-0.19), mildly frail (0.20-0.29), and moderate-to-severely frail (≥ 0.30). Negative binomial regression analyses were used to estimate incident rate ratios (IRRs) of eye care utilization by frailty levels between July 1, 2014, and December 31, 2016. MAIN OUTCOME MEASURES Current Procedural Terminology codes for eye examinations and eye care-related office visits; eye care-related inpatient and emergency department (ED) encounters; eye care-related nursing facility and home-visit encounters; visual field (VF) and retinal nerve fiber layer (RNFL) OCT tests; and selective laser trabeculoplasties (SLTs) and glaucoma surgeries. RESULTS Among 76 260 Medicare beneficiaries with glaucoma, the mean age was 78.9 years (standard deviation, 7.8), female beneficiaries constituted 60.5%, and 78.7% of beneficiaries self-identified as non-Hispanic White. According to a claims-based frailty index, 79.5% of beneficiaries were nonfrail/prefrail, 17.1% were mildly frail, and 3.4% were moderate-to-severely frail. Moderate-to-severely frail beneficiaries were less likely than nonfrail/prefrail beneficiaries to have outpatient encounters (IRR, 0.85, 95% confidence interval [CI], 0.83-0.88); VF tests (IRR, 0.64, 95% CI, 0.60-0.67); RNFL OCT tests (IRR, 0.77, 95% CI, 0.73-0.81); SLT (IRR, 0.74, 95% CI, 0.60-0.92); and glaucoma surgery (IRR, 0.74, 95% CI 0.55-0.99), after adjusting for age, gender, glaucoma severity, race, and socioeconomic status. Compared with nonfrail/prefrail beneficiaries, moderate-to-severely frail beneficiaries had higher rates of inpatient/ED encounters (IRR, 5.03, 95% CI, 2.36-10.71) and nursing facility/home-visit encounters (IRR, 34.89, 95% CI, 14.82-82.13). CONCLUSIONS Compared with nonfrail/prefrail Medicare beneficiaries with glaucoma, beneficiaries with moderate-to-severe frailty had lower rates of eye care utilization in the outpatient setting and higher rates of utilization in acute care settings. This suggests that frail patients may receive less disease monitoring and fewer interventions for their glaucoma management.

Frailty in hypertensive population and its association with all-cause mortality: data from the National Health and Nutrition Examination Survey. Front Cardiovasc Med 2023; 10:945468. [PMID: 37180794 PMCID: PMC10167047 DOI: 10.3389/fcvm.2023.945468] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 04/05/2023] [Indexed: 05/16/2023] Open
Abstract
Objectives This study aimed to investigate the relationship between frailty and all-cause mortality in hypertensive population. Methods We used data from the National Health and Nutrition Examination Survey (NHANES) 1999-2002 and mortality data from the National Death Index. Frailty was assessed using the revised version of the Fried frailty criteria (weakness, exhaustion, low physical activity, shrinking, and slowness). This study aimed to evaluate the association between frailty and all-cause mortality. Cox proportional hazard models were used to evaluate the association between frailty category and all-cause mortality, adjusted for age, sex, race, education, poverty-income ratio, smoking, alcohol, diabetes, arthritis, congestive heart failure, coronary heart disease, stroke, overweight, cancer or malignancy, chronic obstructive pulmonary disease, chronic kidney disease, and taking medicine for hypertension. Results We gathered data of 2,117 participants with hypertension; 17.81%, 28.77%, and 53.42% were classified as frail, pre-frail, and robust, respectively. We found that frail [hazard ratio (HR) = 2.76, 95% confidence interval (CI) = 2.33-3.27] and pre-frail (HR = 1.38, 95% CI = 1.19-1.59] were significantly associated with all-cause mortality after controlling for variables. We found that frail (HR = 3.02, 95% CI = 2.50-3.65) and pre-frail (HR = 1.35, 95% CI = 1.15-1.58) were associated with all-cause mortality in the age group ≥65 years. For the frailty components, weakness (HR = 1.77, 95% CI = 1.55-2.03), exhaustion (HR = 2.25, 95% CI = 1.92-2.65), low physical activity (HR = 2.25, 95% CI = 1.95-2.61), shrinking (HR = 1.48, 95% CI = 1.13-1.92), and slowness (HR = 1.44, 95% CI = 1.22-1.69) were associated with all-cause mortality. Conclusion This study demonstrated that frailty and pre-frailty were associated with an increased risk of all-cause mortality in patients with hypertension. More attention should be paid to frailty in hypertensive patients, and interventions to reduce the burden of frailty may improve outcomes in these patients.

Abstract
BACKGROUND Frailty is linked to poor health outcomes later in life. Recent research suggests that visual loss is a possible modifiable risk factor for frailty. AIMS To analyze the relationship between visual impairment (VI) and frailty and investigate whether it can increase the risk of frailty in older adults. METHODS We performed a systematic review and meta-analysis of cohort studies following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We systematically searched PubMed, Embase, and Scopus databases for relevant studies published between 2012 and 2022 that clearly described VI and frailty measurement methods. Cross-sectional and longitudinal studies that examined the associations between VI and the existence of frailty in adults aged 65 years or older were synthesized. Meta-analyses were conducted using the measurement of risk and a 95% confidence interval for each study. Quality assessment using the Newcastle-Ottawa Scale (NOS), risk of bias, heterogeneity, and sensitivity analyses were also conducted. RESULTS Our search identified 1074 manuscripts published in the English language between 1 January 2012 and 9 June 2022. After studies screening, seventeen articles, including 22,192 participants and 3624 cases of frailty, were selected. A random-effect meta-analysis demonstrated a significant association between visual impairment and the risk of frailty (OR 2.13; 95% CI 1.67-2.72). The quality rating of the cross-sectional studies averaged 8.33 (95% CI 7.77-8.89) of the maximum score on the NOS. CONCLUSIONS Visual impairment increases the risk of frailty in later life and should be accurately assessed in frail older adults.

Abstract
We aimed to assess the associations of peripheral neuropathy (PN) with vision and hearing impairment among adults aged ≥40 years who attended the lower-extremity disease exam for the National Health and Nutrition Examination Survey (United States, 1999-2004). Overall, 11.8% (standard error (SE), 0.5) of adults had diabetes, 13.2% (SE, 0.5) had PN (26.6% (SE, 1.4) with diabetes, 11.4% (SE, 0.5) without diabetes), 1.6% (SE, 0.1) had vision impairment, and 15.4% (SE, 1.1) had hearing impairment. The prevalence of vision impairment was 3.89% (95% CI: 2.99, 5.05) among adults with PN and 1.29% (95% CI: 1.04, 1.60) among adults without PN (P < 0.001). After adjustment, PN was associated with vision impairment overall (odds ratio (OR) = 1.48, 95% confidence interval (CI): 1.03, 2.13) and among adults without diabetes (OR = 1.80, 95% CI: 1.17, 2.77) but not among adults with diabetes (P for interaction = 0.018). The prevalence of hearing impairment was 26.5% (95% CI: 20.4, 33.7) among adults with PN and 14.2% (95% CI: 12.4, 16.3) among adults without PN (P < 0.001). The association of PN with moderate/severe hearing impairment was significant overall (OR = 2.55, 95% CI: 1.40, 4.64) and among adults without diabetes (OR = 3.26, 95% CI: 1.80, 5.91). Overall, these findings suggest an association between peripheral and audiovisual sensory impairment that is unrelated to diabetes.

Self-reported hearing and vision impairment and incident frailty in Japanese older people: A 3-year longitudinal analysis of the Japan Gerontological Evaluation Study. Arch Gerontol Geriatr 2023; 104:104834.

Abstract
BACKGROUND We examined the associations and interactions of hearing impairment (HI) and vision impairment (VI) with frailty. METHODS We performed a 3-year longitudinal analysis of the Japan Gerontological Evaluation Study (JAGES), a nationwide prospective cohort study of functionally independent Japanese older people (age ≥ 65 years). Frailty status at baseline and follow-up was defined according to the Kihon Checklist. HI and VI at baseline were self-reported. Logistic regression models were used to examine the main and interaction effects of HI and VI on incident frailty during a 3-year follow-up period. RESULTS Of the 7,852 participants (mean age 73.2 years, standard deviation 5.6; 50.7% women), 9.7%, 5.3%, and 1.9% reported HI, VI, and concurrent HI and VI, respectively. After adjusting for possible confounders and the other sensory impairment, VI (odds ratio [OR] 2.50, 95% confidence interval [CI] 1.62-3.85, p < 0.001), but not HI (OR 1.29, 95% CI 0.97-1.72, p = 0.081), was significantly associated with incident combined pre-frailty and frailty from a robust baseline. No interaction was observed between HI and VI (OR 0.83, 95% CI 0.38-1.81, p = 0.636). We observed no significant associations between sensory impairments and incident frailty from a pre-frail baseline (HI: OR 1.26, 95% CI 0.88-1.80, p = 0.205; VI: OR 1.44, 95% CI 0.90-2.31, p = 0.127; interaction between HI and VI: OR 1.16, 95% CI 0.53-2.53, p = 0.718). CONCLUSIONS VI, rather than HI, may be an independent risk factor for frailty, without any interaction between the two.

Abstract
Background Disability is globally recognized as a key cause of depression. Likewise, the COVID-19 pandemic has significantly increased the vulnerability of patients with low vision to health and health-related issues, especially mental health. This study aimed to examine the association between the impact of COVID-19 and depressive symptoms in patients with low vision and blindness. Methods This cross-sectional study was conducted between February and July 2022 and involved face-to-face interviews. Patients with low vision and blindness diagnosed with depression were excluded. The following items were included in the questionnaire: sociodemographic information, Multi-Dimensional Scale of Perceived Social Support (MSPSS), the impact of COVID-19, and The Center for Epidemiological Studies-Depression (CES-D). Hierarchical linear regression analysis was used to examine the association between the impact of COVID-19 and depression. Results The prevalence of depression among patients with low vision and blindness was 43.0%. Three factors were associated with depressive symptoms: compliance with COVID-19 prevention strategies (β = 0.16, p<0.01), anxiety during COVID-19 (β = 0.24, p<0.001), and social support (β = -0.16, p<0.01). Conclusion The findings indicated that COVID-19 significantly increased depressive symptoms among patients with low vision and blindness. The psychological effects of the COVID-19 pandemic have been considered critical and emergent public health issues. Stakeholders, particularly public health organizations, need to urgently implement preventive and protective measures to help patients with physical and mental disabilities.

Abstract
OBJECTIVE Approximately 2% of older adults currently live in nursing homes. It is important that the risks for vision loss be characterized to ensure appropriate vision care is provided for nursing home patients. Our objective was to evaluate the association of age-related eye diseases (AREDs) and multimorbidities with vision loss. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS This is a cross-sectional analysis of comprehensive eye examination records for 7753 residents of 74 North Carolina nursing homes who were ≥65 years of age at time of the initial patient visit. METHODS Complete data on vision and associated factors were included from the standardized Centers for Medicare and Medicaid Services eye examination. We defined vision impairment and blindness respectively as best-corrected visual acuity between 20/40 and 20/200, and 20/200 or worse. Clinical diagnoses of AREDs were defined by the attending clinician. Data were extracted from electronic health records, and all analyses were conducted in SAS v 9.4. We used descriptive statistics to summarize the resident characteristics and AREDs and logistic regression analysis to examine independent risk factors for vision impairment. RESULTS A total of 7753 initial eye examination records with complete data were included in the analysis. Overall, 34% of the residents had normal vision, 43% had vision impairment, and 23% were blind. Among participants with various AREDs, the prevalence of vision impaired/blind ranged from 63% to 76%, while blindness ranged from 23% to 53%. We found correction of refractive error alone served to reduce vision impairment or blindness. CONCLUSIONS AND IMPLICATIONS Comprehensive eye examinations showed vision impairment and blindness affected 66% of nursing home residents, overall. This study substantiates the positive impact of comprehensive eye examinations to promote visual, systemic, and cognitive health and well-being and the need that eye care service be used to inform policy and practice to improve patient functioning and independence.

Abstract
Background We have witnessed frailty, which characterized by a decline in physiological reserves, become a major public health issue in older adults. Understanding the influential factors associated with frailty may help prevent or if possible reverse frailty. The present study aimed to investigate factors associated with frailty status and frailty transition in a community-dwelling older population. Methods A prospective cohort study on community-dwelling subjects aged ≥ 60 years was conducted, which was registered beforehand (ChiCTR 2,000,032,949). Participants who had completed two visits during 2020–2021 were included. Frailty status was evaluated using the Fried frailty phenotype. The least absolute shrinkage and selection operator (LASSO) regression was applied for variable selection. Bayesian network analysis with the max-min hill-climbing (MMHC) algorithm was used to identify factors related to frailty status and frailty transition. Results Of 1,981 subjects at baseline, 1,040 (52.5%) and 165 (8.33%) were classified as prefrailty and frailty. After one year, improved, stable, and worsening frailty status was observed in 460 (35.6%), 526 (40.7%), and 306 (23.7%) subjects, respectively. Based on the variables screened by LASSO regression, the Bayesian network structure suggested that age, nutritional status, instrumental activities of daily living (IADL), balance capacity, and social support were directly related to frailty status. The probability of developing frailty is 14.4% in an individual aged ≥ 71 years, which increases to 20.2% and 53.2% if the individual has balance impairment alone, or combined with IADL disability and malnutrition. At a longitudinal level, ADL/IADL decline was a direct predictor of worsening in frailty state, which further increased the risk of hospitalization. Low high-density lipoprotein cholesterol (HDL-C) and diastolic blood pressure (DBP) levels were related to malnutrition, and further had impacts on ADL/IADL decline, and ultimately led to the worsening of the frailty state. Knowing the status of any one or more of these factors can be used to infer the risk of frailty based on conditional probabilities. Conclusion Older age, malnutrition, IADL disability, and balance impairment are important factors for identifying frailty. Malnutrition and ADL/IADL decline further predict worsening of the frailty state. Supplementary Information The online version contains supplementary material available at 10.1186/s12877-022-03520-7.

Relationship between Eye Frailty and Physical, Social, and Psychological/Cognitive Weaknesses among Community-Dwelling Older Adults in Japan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13011.

Abstract
This study investigated the relationship between eye frailty and physical, social, and psychological/cognitive weaknesses among older adults in Japan. The participants were 192 community-dwelling older adult women. We measured handgrip strength, walking speed, and skeletal muscle mass; additionally, their physical, social, and psychological/cognitive frailties were surveyed using questionnaires. Eye frailty self-checks were used to assess eye frailty. Exploratory and confirmatory factor analyses were employed to verify the validity of the eye frailty self-checks. Eye frailty prevalence and related factors were investigated by conducting a binomial logistic regression analysis, with eye frailty as the dependent variable. The factor analysis results showed that a model could be constructed with the two factors of visual acuity or contrast and visual field. The model's goodness of fit was acceptable, supporting the validity of the self-checking construct. The Kihon checklist was the only variable with a significant relationship to eye frailty. Regarding the relationship between eye frailty and subordinate items of the Kihon checklist, social withdrawal [odds ratio (OR) 2.437, 95% confidence interval 1.145-5.188], cognitive function (OR 2.047, 95%CI 1.051-3.984), and depressed mood (OR 1.820, 95%CI 1.163-2.848) were significant. Eye frailty can be considered a factor reflecting the existence of social and psychological/cognitive frailties.

Abstract
Abstract
Background
Frailty has been associated with a decline in sensory and motor function. However, given that different frailty measures were shown to overlap but also differ in their diagnostic properties, sensory and motor correlates of frailty might be different depending on the operationalization of frailty. Our objective was to identify sensory and motor determinants of frailty and compare the results between frailty phenotype (FP) and frailty index (FI).
Methods
Data from 44 pre-frail and frail subjects aged 65 and above were used. Frailty was measured using the FP and the FI. Sensory function in the visual, auditory, and tactile domain was assessed using visual acuity, absolute hearing threshold and mechanical detection threshold. Upper extremity motor performance was evaluated by the Purdue Pegboard Test and the Short Physical Performance Battery was used to assess lower extremity motor function. Multiple logistic regression models were employed to determine associations of sensory and motor function with frailty vs. pre-frailty for both frailty measures.
Results
The frailty measures were moderately correlated (0.497, p ≤ 0.01) and had a Kappa agreement of 0.467 (p = 0.002). Using the FP, frailty was significantly associated with reduced upper extremity motor function only (OR = 0.50, 95% CI 0.29–0.87, p = 0.014). Frailty as assessed by the FI was significantly related to higher hearing thresholds (OR = 1.21, 95% CI 1.02–1.43, p = 0.027) and reduced lower extremity performance (OR = 0.32, 95% CI 0.13–0.77, p = 0.012).
Conclusion
Frailty is related to reduced performance in measures of sensory and motor function. However, traditional measures of frailty might be differentially sensitive to capture sensory and motor decline, possibly contributing to the much-observed discordance between the diagnostic instruments. This should be taken into account by researchers and clinicians when planning and evaluating therapeutic interventions for frailty.

Abstract
Background Vision impairment is common among older adults, and it may be related to frailty. However, the longitudinal relationship between visual impairment and frailty is still unclear. Methods We used data from Round 1 to Round 5 from the National Health and Aging Trend Study. Two samples were community-dwelling older adults, sample 1 (without visual impairment) was classified according to whether they have pre-frailty/frailty at R1 (N = 3013) and sample 2 (without pre-frailty/frailty) was classified according to whether they have visual impairment at R1 (N = 1422), respectively. Frailty was measured using five criteria: experiencing exhaustion, unintentional weight loss, low physical activity, slow gait, and weak grip strength. Visual impairment was assessed by asking participants if they had any visual impairment. Generalized estimating equation models were used to examine the concurrent and lagged association between visual impairment and frailty. Results The participants were on average 76 ± 7 years old, female (59%), non-Hispanic white (74%) with less than bachelor educated (73%), and 44% were pre-frail/frail in the older adults without visual impairment. Approximately 5% of participants had visual impairment at R1, and they tended to be female and non-Hispanic White in the older adults without frailty. The concurrent (OR, 95% CI = 1.55, 1.17-2.02) and lagged (OR, 95% CI = 1.79, 1.25-2.59) associations between frailty and visual impairment were significantly after controlling the covariates. Similarly, the concurrent (OR, 95% CI = 1.63, 1.32-2.04) and lagged (OR, 95% CI = 1.49, 1.20-1.87) associations between visual impairment and frailty were also significant. Conclusions Overall, this study provides evidence for a longitudinal, bidirectional association between self-reported visual impairment and frailty. Future intervention programs to delay frailty progression should include strategies that may reduce the incidence of visual impairment.

BACKGROUND While it is well established that frail older people have a higher risk of negative health outcomes, the prevalence of frailty and its associated factors in Italian older institutionalized population has never been investigated. AIMS The aims of this study were to assess the prevalence of frailty and to identify its associated factors in an Italian residential care home population. METHODS An observational cross-sectional study was designed to evaluate older people aged 70 or over of an Italian residential care home. A multidimensional assessment examining functional, geriatric, ophthalmic, and audiological domains was carried out to identify factors associated with frailty. Physical frailty was evaluated using Fried's criteria. RESULTS Data analysis uncovered a 51.1% prevalence of pre-frailty and a 40.4% prevalence of frailty in the 94 eligible participants (64 females) whose data were complete. The multivariable analysis showed that a low education level (OR = 5.12, 95% CI 1.22-21.49), a low physical quality of life score (OR = 13.25, 95% CI 3.51-50.08), a low mental quality of life score (OR = 9.22, 95% CI 2.38-35.69), visual impairment (OR = 7.65, 95% CI 1.77-33.14), and hearing impairment (OR = 4.62, 95% CI 1.03-20.66) were independently associated with frailty. CONCLUSIONS Frailty was found to be highly prevalent in the residential care home studied. Since frailty is a reversible condition, identifying the modifiable factors associated to it should be viewed as an important step in planning and implementing targeted, early prevention strategies.

Abstract
Objective Hearing and vision loss have been independently associated with frailty in older adults, but the relationship between concurrent hearing and visual impairment (dual sensory impairment) and frailty is not well understood. Therefore, we aimed to examine whether dual sensory impairment is associated with frailty in older adults. Methods This cross-sectional study was based on the data from the West China Health and Aging Trend (WCHAT) study of community-dwelling individuals aged 60 years and older. Frailty status was evaluated by the FRAIL scale and categorized as robust, prefrail and frail. Hearing and vision functions were based on self-report. We used multinomial regression models to explore the association between dual sensory impairment and frailty. Results Of 3985 participants, 1655 (41.5%) were male and the median age was 66 years (interquartile range: 61–68). Overall, 7.6% of participants reported hearing impairment only, 32.7% reported vision impairment only, and 28.6% reported dual sensory impairment. The prevalence of prefrailty and frailty was 60.7% and 6.1%, respectively. After adjustment for confounding variables, results from the multinomial regression analysis showed that dual sensory impairment was significantly associated with greater odds of becoming frail (OR = 2.17, 95% CI = 1.40–3.38) compared with no impairment. When stratified by gender, dual sensory impairment was significantly associated with frailty in women (OR = 2.42, 95% CI = 1.40–4.20) but not in men (OR = 1.30, 95% CI = 0.58–2.91). Conclusion Older adults with dual sensory impairment are more likely to be frail than those with no impairment, suggesting that interventions to improve sensory function may potentially help reduce the risk of frailty in older adults.

Abstract
Background Previous research has suggested that poor oral health is positively associated with frailty. The objective of this study was to explore associations of key oral diseases (periodontal disease, tooth loss), and oral hygiene and management behaviors with the level of frailty in community-dwelling older Korean adults using national representative survey data. Methods This study used cross-sectional, 6th and 7th Korea National Health and Nutrition Examination Survey (KNHANES VI, VII) data. Adults aged 50+ years were included. Frailty was measured using frailty phenotype (FP) and frailty index (FI). FP was determined using five frailty criteria, i.e., weight loss, weakness, exhaustion, slowness, or low physical activity, and the level of frailty was classified with the number of criteria present (robust, none; pre-frail, 1–2; frail, 3+). FI was determined using a 44-item FI constructed according to a standard protocol, and the level of frailty was classified as robust (FI: ≤ 0.08), pre-frail (FI: 0.08–0.25), and frail (FI: ≥ 0.25). Multiple ordinal regression analyses were conducted with each type of frailty as the outcome variable. Independent variables of interest were the periodontal status, number of teeth, and practices on oral hygiene and management. Analyses were additionally adjusted for participants’ socioeconomic, diet, and behavioral characteristics. Results The prevalence of frailty was 4.38% according to the FP classification (n = 4156), 10.74% according to the FI classification (n = 15,073). In the final adjusted model, having more teeth and brushing after all three meals were significantly associated with lower odds of being more frail (in both frailty models); no significant association was observed between periodontal disease and frailty. Conclusions Findings from this study show having more teeth and practicing adequate brushing are significantly associated with frailty. Due to limitations of the study design, well-designed longitudinal studies are needed to confirm these findings.

Abstract
OBJECTIVES Our study aims to explore the association between ultra-processed foods (UPFs) and frailty in participants with different body mass indexes (BMIs). DESIGN A cross-sectional study. SETTING Data were collected from the National Health and Nutrition Examination Survey (NHANES) 1999-2000 and 2001-2002. PARTICIPANTS We analyzed data from 2,329 participants. MEASUREMENTS Dietary data were obtained using 24-h dietary recall method. Frail status was assessed by modified Fried frailty phenotype. The association between the grams, energy, and energy proportion of UPFs and the risk of pre-frailty/frailty was estimated using logistic regression analysis, and odds ratio (OR) with 95% confidence intervals (CIs) were calculated. Participants were categorized into underweight-normal weight (BMI <25 kg/m2), overweight (25 kg/m2 ≤ BMI < 30 kg/m2), and obesity (BMI ≥ 30 kg/m2) groups. The multiplicative interaction between BMIs and UPFs on pre-frailty/frailty was assessed using the logistic regression analysis. RESULTS We analyzed data from 2,329 participants, and 2,267 (97.77%) of whom consumed UPFs. There were 1,063 participants in pre-frailty or frailty group and 1,266 participants in non-frailty group. In underweight-normal weight participants, every 100 kcal increase in energy of UPFs intake was associated with increased 0.08 times of pre-frailty or frailty risk (OR: 1.08, 95%CI: 1.00-1.16, P = 0.045), and every 10% increase in energy proportion of UPFs intake was correlated with a 0.02-fold increase in pre-frailty or frailty risk (OR: 1.02, 95%CI: 1.00-1.03, P = 0.018). Similar results were found in overweight participants, with OR of 1.06 (95%CI: 1.01-1.10) and 1.01 (95%CI: 1.00-1.02) for energy and energy proportion, respectively (both P < 0.05). This association was not found in obesity participants. CONCLUSION The energy and energy proportion of UPFs intake was positively associated with the frailty risk in underweight-normal weight and overweight people, indicating that population with BMI less than 30 kg/m2 should pay more attention to reasonable diet and balanced source of energy intake.

Abstract
INTRODUCTION Very little is known about the impact of vision impairment (VI) on physical health in late-life in sub-Saharan Africa populations, whereas many older people experience it. We investigated the association between self-reported VI and frailty in Central African older people with low cognitive performance. METHODS It was cross-sectional analysis of data from the Epidemiology of Dementia in Central Africa (EPIDEMCA) population-based study. After screening for cognitive impairment, older people with low cognitive performance were selected. Frailty was assessed using the Study of Osteoporotic Fracture index. Participants who met one of the 3 parameters assessed (unintentional weight loss, inability to do 5 chair stands, and low energy level) were considered as pre-frail, and those who met 2 or more parameters were considered as frail. VI was self-reported. Associations were investigated using multinomial logistic regression models. RESULTS Out of 2,002 older people enrolled in EPIDEMCA, 775 (38.7%) had low cognitive performance on the screening test. Of them, 514 participants (sex ratio: 0.25) had available data on VI and frailty and were included in the analyses. In total, 360 (70%) self-reported VI. Prevalence of frailty was estimated at 64.9% [95% confidence interval: 60.9%-69.1%] and 23.7% [95% CI: 20.1%-27.4%] for pre-frailty. After full adjustment, self-reported VI was associated with frailty (adjusted odds ratio = 2.2; 95% CI: 1.1-4.3) but not with pre-frailty (adjusted odds ratio = 1.8; 95% CI: 0.9-3.7). CONCLUSION In Central African older people with low cognitive performance, those who self-reported VI were more likely to experience frailty. Our findings suggest that greater attention should be devoted to VI among this vulnerable population in order to identify early frailty onset and provide adequate care management.

Abstract
BACKGROUND There are currently no studies on visual impairment and sarcopenia. We investigated the cross-sectional association between objectively measured far vision impairment and sarcopenia in a nationally representative sample of older adults aged 65 years and over from six low- and middle-income countries (LMICs). METHODS Cross-sectional, community-based data from the study on global ageing and adult health (SAGE) were analyzed. Far vision acuity was measured using the tumbling E LogMAR chart and classified as: no vision impairment (6/12 or better); mild vision impairment (6/18 or better but worse than 6/12); moderate vision impairment (6/60 or better but worse than 6/18); severe vision impairment (worse than 6/60). Sarcopenia was defined as having low skeletal muscle mass and either a slow gait speed or a weak handgrip strength. Associations were assessed with multivariable logistic regression. RESULTS Fourteen thousand five hundred and eighty five individuals aged ≥ 65 years were included in the analysis [mean (SD) age 72.6 (11.5) years; 54.1% females]. After adjustment for multiple potential confounders, compared to those with no vision impairment, the OR (95% CI) for sarcopenia in those with mild, moderate, and severe vision impairment were 1.10 (0.87-1.40), 1.69 (1.25-2.27), and 3.38 (1.69-6.77), respectively. The estimates for females and males were similar. CONCLUSIONS The odds for sarcopenia increased with increasing severity of far vision impairment among older people in LMICs. The mere co-occurrence of these conditions is concerning, and it may be prudent to implement interventions to address/prevent sarcopenia in those with far vision impairment through the promotion of physical activity and appropriate nutrition.

Abstract
Given the interdependence of multiple factors in age-related vestibular loss (e.g., balance, vision, cognition), it is important to examine the individual contributions of these factors with ARVL. While the relationship between the vestibular and visual systems has been well studied (Bronstein et al., 2015), little is known about the association of the peripheral vestibular system with neurodegenerative disorders (Cronin et al., 2017). Further, emerging research developments implicate the vestibular system as an opportunity for examining brain function beyond balance, and into other areas, such as cognition and psychological functioning. Additionally, the bidirectional impact of psychological functioning is understudied in ARVL. Recognition of ARVL as part of a multifaceted aging process will help guide the development of integrated interventions for patients who remain at risk for decline. In this review, we will discuss a wide variety of characteristics of the peripheral vestibular system and ARVL, how it relates to neurodegenerative diseases, and correlations between ARVL and balance, vision, cognitive, and psychological dysfunction. We also discuss clinical implications as well as future directions for research, with an emphasis on improving care for patients with ARVL.

Abstract
BACKGROUND It is unclear whether visual and hearing acuity are independently or synergistically associated with muscle strength. We aimed to examine the associations of visual and self-reported hearing acuity with low handgrip strength and the additive interaction between visual and hearing acuity on low handgrip strength in people over 60 years. METHOD Data of 3,075 individuals aged over 60 years from the 2017 and 2018 Korea National Health and Nutrition Examination Survey were used for this cross-sectional study. Low handgrip strength was defined based on the 20th percentile of the study population (< 30.4 kg for male and < 17.7 kg for female). Visual and self-reported hearing acuity were each divided into three categories: good, moderate, and impaired. Multiple logistic regression and relative excess risk due to interaction (RERI) were performed. RESULTS Of the 3,075 participants, 993 (32.3 %) demonstrated low handgrip strength. Low handgrip strength was more prevalent in participants with moderate (adjusted odds ratio [AOR] = 1.54, 95 % confidence interval [CI] = 1.12-2.12) and impaired visual acuity (AOR = 2.00, 95 % CI = 1.34-2.96). Both moderate and impaired self-reported hearing acuity were significantly associated with low handgrip strength (moderate: AOR = 1.25, 95 % CI = 1.01-1.55; impaired: AOR = 1.66, 95 % CI = 1.15-2.38). The more severe the sensory function decline, the higher the association with muscle weakness. Moreover, combined sensory impairments were associated with deteriorating low handgrip strength (AOR = 8.38), with significantly strong additive interactions (RERI = 2.61, 95 % CI = 2.52-2.70). CONCLUSIONS Awareness is needed regarding the risk of reduced muscle strength in individuals with moderate and impaired sensory function. Older people with sensory function decline in clinical settings may benefit from programs such as exercise prescription to prevent muscle weakness.

Abstract
BACKGROUND Visual impairment (VI) may lead to worsening functional status and disability. Although disability is very difficult to reverse, it is usually preceded by frailty that may be reverted more easily. It is possible that VI is also related to frailty. AIMS To assess the relationship between VI and worsening of the frailty status. METHODS Data were taken from the Toledo Study for Healthy Aging (TSHA), a cohort study of community-dwelling people older than 65 years living in one Spanish province who were followed for 5 years. 1181 participants were included. VI was self-reported and frailty was operationalized using the Fried's phenotype adapted to a Spanish population. Models of multivariate logistic regression were built to assess the associations. RESULTS The mean age was 73.9 (Standard Deviation (SD) = 5 years) and 58.5% were females. Pre-frailty/frailty prevalence at baseline and follow-up were 41.2/5% and 36.2/12.5%, respectively, and VI was reported by 14.1%. After adjusting for age, gender, education level, tobacco consumption, type 2 diabetes mellitus, high blood pressure, cardiovascular disease, depressive symptoms and cognitive status, odds ratios for the development of frailty by VI were 2.5 (95% Confidence Interval (CI) 1.5-4.4) for non-frail, 2.7 (95% CI 1.3-5.7) for pre-frail and 1.9 (CI 0.6-6.00) for robust participants. The frailty domains whose appearance was most increased by VI were slowness, low energy, low physical activity and weakness. DISCUSSION Our findings support that VI worsens frailty in the early stages of its development (pre-frailty). VI impairs several frailty items at the same time. CONCLUSIONS Our study highlights the need to assess both VI and frailty for the prevention of frailty and disability in older people.

Abstract
BACKGROUND Visual impairment is associated with deficits in cognitive function and risk for cognitive decline and Alzheimer's disease (AD). OBJECTIVE The purpose of this study was to characterize the degree of visual impairment and explore the association thereof with cortical atrophy in brain regions associated with visual processing in individuals with (or at risk for) AD. METHODS Using the Comprehensive Assessment of Neurodegeneration and Dementia (COMPASS-ND) dataset, we analyzed vision and brain imaging data from three diagnostic groups: individuals with subjective cognitive decline (SCD; N = 35), mild cognitive impairment (MCI; N = 74), and mild AD (N = 30). We used ANCOVAs to determine whether performance on reading acuity and contrast sensitivity tests differed across diagnostic groups. Hierarchical regression analyses were applied to determine whether visual performance predicted gray matter volume for vision-related regions of interest above and beyond group membership. RESULTS The AD group performed significantly worse on reading acuity (F(2,138) = 4.12, p < 0.01, ω 2 = 0.04) compared to the SCD group and on contrast sensitivity (F(2,138) = 7.6, p < 0.01, ω 2 = 0.09) compared to the SCD and MCI groups, which did not differ from each other. Visual performance was associated with volume in some vision-related structures beyond clinical diagnosis. CONCLUSION Our findings demonstrate poor visual performance in AD and that both group membership and visual performance are predictors of cortical pathology, consistent with the idea that atrophy in visual areas and pathways contributes to the functional vision deficits observed in AD.

Abstract
Purpose TO assess perceptions and implications of COVID-19 infection across the spectrum of individuals with visually impairment (VI) and those with normal sight. Design Prospective cross-sectional comparative study. Methods Setting: institutional. Patients: 232 patients and their caregivers. Four groups were created based on better eye characteristics: blind (best-corrected distance visual acuity [BCDVA] <3/60 or visual field <10 central degrees); severe VI (BCDVA ≤3/60 to <6/60; vertical cup-to-disc ratio ≥0.85 or neuroretinal rim width ≤0.1); moderate VI (BCDVA ≤6/60 to <6/18); or no or mild VI (controls: BCDVA ≥6/18) based on International Classification of Diseases-10 criteria and Foster and Quigley's consensus definition of glaucoma. Procedure: telephone questionnaires. Main outcome measures: differences in perceptions and implications of COVID-19 infection across various levels of VI. Caregiver perceptions were a secondary outcome measure. Results Surveys were completed by 232 participants, with 58 participants in each VI group. Mean age was 58.9 ± 13.2 years old. Greater degrees of VI were associated with older age (P = .008) and lower education level (P = .046). Blind participants more commonly perceived vision as a risk factor for contracting COVID-19 (P = .045), were concerned about access to health care (P <.001), obtained news through word of mouth (P <.001), and less commonly wore masks (P = .003). Controls more commonly performed frequent handwashing (P = .001), were aware of telemedicine (P = .029), and had fewer concerns about social interactions (P = .020) than groups with substantial VI. All caregivers reported more frequent patient care since the COVID-19 pandemic began. Conclusions The pandemic might have had a disproportionate impact on the visually impaired, and evidence-based assessments of COVID-19 health outcomes in this population are warranted.

Abstract
Factors associated with frailty, particularly dietary patterns, are not fully understood in Mediterranean countries. This study aimed to investigate the association of data-driven dietary patterns with frailty prevalence in older Lebanese adults. We conducted a cross-sectional national study that included 352 participants above 60 years of age. Sociodemographic and health-related data were collected. Food frequency questionnaires were used to elaborate dietary patterns via the K-mean cluster analysis method. Frailty that accounted for 15% of the sample was twice as much in women (20%) than men (10%). Identified dietary patterns included a Westernized-type dietary pattern (WDP), a high intake/Mediterranean-type dietary pattern (HI-MEDDP), and a moderate intake/Mediterranean-type dietary pattern (MOD-MEDDP). In the multivariate analysis, age, waist to height ratio, polypharmacy, age-related conditions, and WDP were independently associated with frailty. In comparison to MOD-MEDDP, and after adjusting for covariates, adopting a WDP was strongly associated with a higher frailty prevalence in men (OR = 6.63, 95% (CI) (1.82-24.21) and in women (OR = 11.54, 95% (CI) (2.02-65.85). In conclusion, MOD-MEDDP was associated with the least prevalence of frailty, and WDP had the strongest association with frailty in this sample. In the Mediterranean sample, a diet far from the traditional one appears as the key deleterious determinant of frailty.

Screening for intrinsic capacity impairments as markers of increased risk of frailty and disability in the context of integrated care for older people: Secondary analysis of MAPT. Maturitas 2021; 150:1-6. [PMID: 34274071 DOI: 10.1016/j.maturitas.2021.05.011] [Citation(s) in RCA: 29] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 04/29/2021] [Accepted: 05/31/2021] [Indexed: 01/01/2023]
Abstract
AIM This longitudinal secondary analysis of the Multidomain Alzheimer Preventive Trial (MAPT) aimed to test whether the Integrated Care for Older People (ICOPE) Step 1 screening tool is able to identify people at risk of developing frailty and disability in basic (ADL) and instrumental (IADL) activities of daily living among community-dwelling older adults. PARTICIPANTS AND SETTING Seven hundred and fifty-nine (n = 759) non-demented participants of the MAPT aged 70-89 years were assessed in memory clinics in France between 2008 and 2013. METHODS We measured six intrinsic capacity (IC) impairments, adapted from the ICOPE screening tool. We used Cox models to estimate the adjusted hazard ratios of incident frailty and IADL/ADL disability. Incident frailty was defined by Fried's phenotype, and incident disability was measured according to Lawton and Katz for IADLs and ADLs. RESULTS Limited mobility (HR= 2.97, 95%CI= 1.85-4.76), depressive symptoms (HR= 2.07, 95%CI= 1.03-4.19), and visual impairment (HR= 1.70, 95%CI 1.01-2.86) were associated with a higher incidence of frailty over 5 years. Each additional IC condition demonstrated a positive association with a higher risk of incident frailty, IADL, ADL disability, with risk increased by 47%, 27%, and 23% over 5 years, respectively. CONCLUSION Screening for IC impairments identifies older adults at higher risk of incident frailty and incident IADL/ADL disability. It is relevant to screen for these impairments together because the risk of frailty and disability increases with each additional one. ClinicalTrials.gov identifier: NCT00672685.

Abstract
PURPOSE Using data from the Malaysian Elders Longitudinal Research (MELoR), this study investigated the association between visual function (visual acuity and contrast sensitivity) and frailty in a group of urban-dwelling older adults. METHODS This was a cross-sectional study. 1332 participants aged ≥ 55 years were selected by random sampling from the parliamentary electoral register. Only 1274 participants completed the frailty assessment and 1278 participants completed the contrast sensitivity assessment. Impaired vision was defined as a Snellen visual acuity of worse than 6/12 in the better eye. Poor contrast sensitivity was defined as a score on the Pelli Robson chart of lower than 1.65. Frailty was defined with the Fried's phenotype criteria. Inter-group comparisons were determined with the independent T-test for continuous variables and the Pearson's Chi-squared test for categorical variables. The odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the cross-sectional association between frailty and visual function. RESULTS The mean age of participants was 68.8 ± 7.5 years, of which 58.1% (774) were women. Impaired vision and poor contrast sensitivity were present in 187 (14%) and 271 (21.2%) subjects respectively. 73 (5.8%) individuals were classified as frail, 1161 (91.0.%) pre-frail, and 40 (2.8%) non-frail. There was no significant difference in frailty phenotypes between those with good and impaired vision (p = 0.241). Fried's component of handgrip strength, gait speed and exhaustion were significantly better in those with good visual function (p < 0.05). Participants with poor contrast sensitivity were significantly more likely to be frail (OR: 5.34, p = 0.004). CONCLUSION Poor contrast sensitivity was significantly associated with frailty. This highlights the importance of incorporating assessment of contrast sensitivity in those at risk of frailty.

Abstract
Previous reports have described close relationships between sarcopenia and either visual impairment or depression, but there have been few analyses investigating the association between sarcopenia and the coexistence of both visual impairment and depression. Herein, we sought to explore the associations between sarcopenia and comorbid depressive symptoms and visual impairment among older females. A cross-sectional analysis of females between the ages of 50 and 95 (n = 2454) from the West China Health and Aging Trend (WCHAT) study was conducted. Patient muscle mass was assessed via a bioimpedance-based approach using an InBody 770 device, while muscle strength was estimated based on handgrip strength as quantified with a digital grip strength dynamometer. Depressive systems were evaluated with the 15-item Geriatric Depression Scale (GDS-15), and a questionnaire was employed to evaluate patient visual functionality. Associations between sarcopenia and comorbid depressive status and visual impairment were explored through logistic regression analyses. Comorbid depressive symptoms and visual impairment were observed in 6.2% of the women included in this study, while 18.9% suffered from sarcopenia. Following adjustment for covariates, relative to normal controls, study subjects with only depression (OR=1.45, 95%CI=1.04-2.02), only visual impairment (OR=1.69, 95%CI=1.27-2.26), or comorbid depression and visual impairment (OR=1.76, 95% CI=1.16-2.67) exhibited a higher risk of sarcopenia. These results suggest that comorbid depression and visual impairment are linked to the prevalence of sarcopenia in older Chinese women. As such, further efforts to screen older women for these two comorbid conditions may thus be necessary.

Abstract
Frailty is a dynamic process. Identifying the factors associated with frailty transition may increase the opportunities for success in interventions for frailty. This scoping review, following Arksey and O'Malley's methodological framework, aimed to identify the factors associated with frailty transition and the rate of frailty transition among community-dwelling older people. A literature search was conducted. Among the included studies, 5, 13, and 3 involved follow-up intervals of 2-3 years (short term), 4-6 years (intermediate term), and >6 years (long term), respectively. Reportedly, life course characteristics, diseases, and psychological factors were related to frailty transitions at all follow-up intervals. Physical factors were related to frailty transition at both short and intermediate follow-up intervals, while social factors were related to frailty transition at intermediate follow-up intervals. The rate of improvement in frailty seemed to decrease, and that of worsening seemed to increase when the follow-up intervals lengthened.

Abstract
OBJECTIVES To examine data from Delaware nursing homes to determine prevalence of age-related eye diseases (AREDs), vision impairment, and blindness and to compare the findings with the results of 11 US investigations of vision and eye health in nursing homes. DESIGN This is a cross-sectional, retrospective study of nursing home patients. SETTING AND PARTICIPANTS Twenty nursing homes in Delaware participated in the study, yielding comprehensive eye examination records for 2019 study participants. METHODS Summary statistics and regression analyses. RESULTS The overall prevalence of vision impairment or blindness was 63.8% and was above 60% for each age, sex, and race category. Prevalence of vision impairment or blindness was 68.4% among patients with cataracts, 69.4% among patients with macular degeneration, 70.5% among patients with glaucoma, and 68.4% among patients with diabetic retinopathy. Prevalence of blindness was 14.1%. Among patients with AREDs, prevalence of blindness ranged from 15.0% for patients with cataracts to 22.6% for patients with diabetic retinopathy. When compared with other investigations, we found wide variation in vision and eye factors reported and wide variation in the prevalence of those factors. Only 4 studies diagnosed both AREDs and visual function. Seven studies reported AREDs, and 7 reported vision impairment and/or blindness. Vision impairment or blindness ranged from 29% to 67%; cataract ranged from 32% to 83%; macular degeneration ranged from 4.6% to 70.7%. Glaucoma ranged from 5.3% to 41.4%; diabetic retinopathy ranged from 1.7% to 3.1%. CONCLUSIONS AND IMPLICATIONS Comprehensive eye examinations showed that vision impairment and blindness affected 63.8% of nursing home residents. Compared with other studies, there was a wide range of vision factors reported and wide variation in the prevalence of vision impairment or blindness and AREDs. This investigation suggests the importance of eye care in nursing homes and the importance of reporting standard vision and eye health factors to inform policy and practice.

Abstract
AbstractBackgroundAge-related sensory loss and frailty are common conditions among older adults, but epidemiologic research on their possible links has been inconclusive. Clarifying this relationship is important because sensory loss may be a clinically relevant risk factor for frailty.MethodsIn this systematic review and meta-analysis, we searched 3 databases for observational studies investigating 4 sensory impairments—vision (VI), hearing (HI), smell (SI), and taste (TI)—and their relationships with frailty. We meta-analyzed the cross-sectional associations of VI/HI each with pre-frailty and frailty, investigated sources of heterogeneity using meta-regression and subgroup analyses, and assessed publication bias using Egger’s test.ResultsWe included 17 cross-sectional and 7 longitudinal studies in our review (N = 34,085) from 766 records. Our cross-sectional meta-analyses found that HI and VI were, respectively, associated with 1.5- to 2-fold greater odds of pre-frailty and 2.5- to 3-fold greater odds of frailty. Our results remained largely unchanged after subgroup analyses and meta-regression, though the association between HI and pre-frailty was no longer significant in 2 subgroups which lacked sufficient studies. We did not detect publication bias. Longitudinal studies largely found positive associations between VI/HI and frailty progression from baseline robustness, though they were inconclusive about frailty progression from baseline pre-frailty. Sparse literature and heterogenous methods precluded meta-analyses and conclusions on the SI/TI–frailty relationships.ConclusionsOur meta-analyses demonstrate significant cross-sectional associations between VI/HI with pre-frailty and frailty. Our review also highlights knowledge gaps on the directionality and modifiability of these relationships and the impact of SI/TI and multiple sensory impairments on frailty.

Abstract
PURPOSE To examine associations between near vision impairment (NVI) and frailty. DESIGN Cross-sectional study. METHODS Setting: Nationally representative sample of noninstitutionalized United States civilians. STUDY POPULATION Total of 2705 older adults aged ≥60 years from National Health and Nutrition Examination Survey (1999-2002). OBSERVATION Presenting NVI (PNVI): near acuity worse than 20/40. Self-reported NVI (SNVI): self-reported difficulty with near vision tasks. MAIN OUTCOME MEASURE(S) Five-item physical frailty index; participants classified as frail (≥3 criteria) and prefrail (1 or 2 criteria). Propensity score-adjusted and probability-weighted multinomial multivariable logistic regression was used to examine associations of PNVI and SNVI with frailty. RESULTS Of 2705 participants, 381 (10%), 160 (5%), and 106 (3%) had PNVI only, SNVI only, and PNVI+SNVI, respectively. In fully adjusted models, as compared to those without PNVI, participants with PNVI were more likely to be prefrail (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.1, 2.3) and frail (OR = 2.5; 95% CI = 1.4, 4.3). As compared to those without SNVI, participants with SNVI were more likely to be prefrail (OR = 2.9; 95% CI = 1.8, 4.7) and frail (OR = 4.3; 95% CI = 2.2, 8.3). As compared to those without PNVI or SNVI, participants with PNVI+SNVI were more likely to be prefrail and frail (prefrail: OR = 4.0; 95% CI = 2.2, 7.2 and frail: OR = 4.5; 95% CI = 1.7,12.7). CONCLUSIONS Older adults with PNVI and SNVI were more likely to be prefrail and frail than those without respective NVI, suggesting that NVI is associated with frailty.
