The Quantitative Impact of Visual Function on Accelerometer-measured Physical Activity in Older United States Adults: A Nationwide Cross-sectional Analysis

Purpose

To explore the impact of objective vision measures on novel metrics of objectively-measured physical activity (PA) in a nationally representative sample of United States (US) older adults.

Design

Cross-sectional analysis using data from the National Health and Aging Trends Study.

Participants

Adults had their distance and near visual acuity (VA) and contrast sensitivity (CS) tested. Any objective vision impairment (VI), defined as any VI in distance VA, near VA, or CS, was the primary exposure. Physical activity data were collected using the Actigraph CentrePoint Insight Watch worn for 7 days.

Methods

Multivariable regression models were used to investigate the association between vision and PA measures. All analyses accounted for the survey design and models were adjusted for age, sex, race, living arrangement, education, and comorbidities.

Main Outcome Measures

Physical activity metrics included (1) total daily activity (active minutes per day, number of active bouts, and mean length of active bouts), (2) activity fragmentation, and (3) time until 75% activity. An active bout was defined as ≥ 1 consecutive active minute. Activity fragmentation was defined as the probability of an active minute being followed by a sedentary minute, with higher values indicating more fragmented activity. Time until 75% activity was defined as the time taken to complete 75% of daily PA starting from their first active bout.

Results

Among 723 participants, sampled from 10 443 338 older adults in the US, 30% had any objective VI. Any objective VI was significantly associated with lower number of active minutes per day (7.8% fewer [95% confidence interval {CI}: -13.6% to -1.7%]), shorter active bouts (7.0% shorter [95% CI: -12.3% to -1.4%]), and greater activity fragmentation (2.5% [95% CI: 0.8% to 4.2%]), while no associations were found with number of active bouts. Time until 75% activity did not significantly differ between adults with any objective VI and those without (P = 0.34).

Conclusions

Older US adults with any objective VI displayed lower total daily activity, as well as more fragmented, shorter periods of PA, despite having a similar number of active bouts compared to their normally sighted counterparts. Implementing interventions that increase bout duration may help promote PA in adults with VI.

Digital Technology Use Among Older Adults With Vision Impairment

Importance

Telehealth has the potential to improve health for older adults, but many access disparities exist, including for those with vision impairment (VI).

Objective

To examine the associations between VI and digital technology access measures in US older adults.

Design, Setting, and Participants

This was a cross-sectional study that included Medicare beneficiaries 65 years and older. Beneficiary data were obtained from the National Health and Aging Trends Study (NHATS) 2021; data collection was conducted from June 2020 through January 2021. Data were analyzed September 2023.

Exposure

VI, measured on categorical (distance and near VI [>0.30 logMAR], contrast sensitivity impairment [CSI; <1.55 logCS], and any VI [distance VI, near VI, or CSI]), and continuous (distance and near acuity [logMAR] and contrast sensitivity [logCS]) scales.

Main Outcomes

Self-reported outcomes of digital technology access from the technological environment component of the NHATS.

Results

Of the 2822 Medicare beneficiaries (mean [SD] age, 78.5 [5.6] years; 1605 female [54.7%]) included in this study, patients self-identified with the following race and ethnicity categories (weighted percentages): 575 non-Hispanic Black (8.0%), 132 Hispanic (7.0%), 2019 non-Hispanic White (81.7%), and 63 non-Hispanic other race (3.4%), which included American Indian, Alaska Native, Asian, multiracial, Native Hawaiian, Pacific Islander, or other specified race. A total of 1077 of 2822 patients (32.3%) had any VI. In multivariable logistic regression models, older adults with any VI had lower odds of having or knowing how to use a cellphone (odds ratio [OR], 0.58; 95% CI, 0.38-0.88), computer (OR, 0.61; 95% CI, 0.47-0.79), or tablet (OR, 0.68, 95% CI = 0.54-0.85) than peers without VI. In other models, near VI was associated with lower odds of having and knowing how to use a phone (OR, 0.56; 95% CI, 0.36-0.87), computer (OR, 0.57; 95% CI, 0.44-0.75), or tablet (OR, 0.65; 95% CI, 0.52-0.81) compared with no near VI. CSI was associated with lower odds of having and knowing how to use a phone (OR, 0.66; 95% CI, 0.45-0.99) or computer (OR, 0.72; 95% CI, 0.55-0.93) compared with no CSI. Distance VI was only associated with lower odds of having and knowing how to use a cellphone (OR, 0.63; 95% CI, 0.41-0.95). Any VI and individual categorical VI measures were not associated with other outcomes of digital health- and nonhealth-related experiences. Similar associations were noted when vision was examined on a continuous scale. However, worse distance acuity (per 0.1 logMAR) was associated with being less likely to visit with family or friends on a video call (OR, 0.91; 95% CI, 0.84-0.98) and to order or refill prescriptions online (OR, 0.90; 95% CI, 0.83-0.97).

Conclusions and Relevance

Results suggest that older US adults with VI were less likely to have access to digital technology than peers without VI, although no differences were noted in the report of digital health- and nonhealth-related activities. These findings highlight the potential for inequities that may arise in telehealth for older adults with VI and the necessity to develop strategies to improve accessibility of telemedicine for all.

Vision impairment and food insecurity in the national health and aging trends study

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.

Vision Impairment and Psychosocial Function in US Adults

Importance

Vision impairment and psychosocial function, including symptoms of depression and anxiety and social isolation, are a major cause of morbidity in the US. However, there is a lack of nationally representative studies assessing associations between both objective and subjective vision impairment with psychosocial function following the COVID-19 pandemic.

Objective

To provide updated national estimates on the associations of vision impairment with depressive and anxiety symptoms and social isolation in US adults 65 years and older.

Design, Setting, and Participants

This was a cross-sectional analysis of the National Health and Aging Trends Study round 9 (2019) and 11 (2021), a nationally representative sample of Medicare beneficiaries aged 65 years and older. Binocular distance visual acuity, near visual acuity, and contrast sensitivity were tested. Objectively measured vision impairment was defined as having vision impairment in either distance visual acuity (worse than 20/40), near visual acuity (worse than 20/40), or contrast sensitivity (worse than 1.55 logCS). Self-reported vision impairment was defined based on participants' report on their vision status. Data were analyzed in May 2023.

Main Outcomes and Measures

Depressive and anxiety symptoms assessed via the Patient Health Questionnaire. Social isolation was defined based on living arrangement, communication frequency, and activity participation responses.

Results

Among 2822 community-dwelling adults sampled from a population of 26 182 090, the mean (SD) age was 78.5 (5.6) years; 1605 individuals (54.7%) were female; 1077 (32.3%) had objectively measured vision impairment, and 203 (6.4%) had self-reported vision impairment. In adjusted models, all outcomes were significantly associated with objectively measured vision impairment, including depressive symptoms (odds ratio [OR], 1.81; 95% CI, 1.26-2.58), anxiety symptoms (OR, 1.74; 95% CI, 1.13-2.67), and severe social isolation (OR, 2.01; 95% CI, 1.05-3.87). Similarly, depressive symptoms (OR, 2.37; 95% CI, 1.44-3.88) and anxiety symptoms (OR, 2.10; 95% CI, 1.09-4.05) but not severe social isolation symptoms (OR, 2.07; 95% CI, 0.78-5.49) were significantly associated with self-reported vision impairment.

Conclusions and Relevance

In this study, vision impairment was associated with several psychosocial outcomes, including symptoms of depression and anxiety and social isolation. These findings provide evidence to support prioritizing research aimed at enhancing the health and inclusion of people with vision impairment.

Population prevalence of dual sensory loss in community-dwelling US adults 71 years and older: Evidence from the National Health and Aging Trends Study

BACKGROUND

Existing estimates for the prevalence of dual sensory loss (vision and hearing) among older adults are either based on self-reported measures or aggregated for older age groups. Current and detailed estimates based on objective measures are needed for public health, clinical, and policy decision-making.

METHODS

We estimated the prevalence of dual sensory loss (DSL) using National Health Aging Trends Study (NHATS) Round 11 data (2021). We restricted to community-dwelling adults aged ≥71 years with complete sensory testing data (N = 2579). Hearing loss was defined by a 4-frequency (0.5, 1, 2 and 4 kHz) pure tone average for the better-hearing ear (>25 decibel hearing level). Vision loss was defined by the presence of distance, near (logarithm of the minimum angle of resolution >0.30), or contrast sensitivity loss (log contrast sensitivity <1.55). Participants were categorized into three groups: no sensory loss, single sensory loss (vision or hearing loss), and DSL (hearing and vision). Sensory loss prevalence was estimated by age group and sociodemographic characteristics.

RESULTS

In weighted analyses, among older Medicare beneficiaries (53% female, 7% Black, 6% Hispanic), 28% had no sensory loss and 22% had DSL. Prevalence of DSL increased with age. Most adults aged ≥90 years experienced DSL (59%), as opposed to single (39%) or no sensory loss (2%). DSL prevalence was greater among older adults with low education attainment (34%) and household income (43%). A higher proportion of older adults with a college education (17%), or from wealthier households (16%), had no sensory loss.

CONCLUSIONS

One in 5 community-dwelling Medicare beneficiaries aged ≥71 years have DSL, increasing to 3 in 5 for those aged ≥90 years. Prevalence is higher among older adults with low education attainment and from low-income households, characteristics associated with low treatment. Policies increasing access and affordability of vision and hearing care could benefit millions of older Americans experiencing sensory loss.

Factors Associated With Receipt of Crosslinking for Keratoconus

PURPOSE

The aim of this study was to identify factors associated with receipt of standard fluence epithelium-off crosslinking (CXL) for keratoconus (KCN).

METHODS

This retrospective, cross-sectional study reviewed electronic health records of treatment-naive patients with KCN seen at the Wilmer Eye Institute between January 2017 and September 2020. Tomographic data were derived from Pentacam (Oculus, Wetzlar, Germany) devices. Multivariable population-average model using generalized estimating equations adjusting for age, sex, race, national area deprivation index, vision correction method, and disease severity was used to identify factors associated with receipt of CXL.

RESULTS

From 583 patients with KCN, 97 (16.6%) underwent CXL for KCN. Patients who received CXL in at least 1 eye were significantly younger (mean 24.0 ± 7.8 years) than patients who had never undergone CXL (33.4 ± 9.3 years) ( P < 0.001). In multivariable analysis, Black patients had 63% lower odds of receiving CXL for KCN (OR: 0.37, 95% CI, 0.18-0.79) versus White patients, and older age was protective against receipt of CXL (OR: 0.89 per 1-year increase, 95% CI, 0.86-0.93). Comparison of characteristics by race demonstrated that Black patients presented with significantly worse vision, higher keratometric indices (K1, K2, and Kmax), and thinner corneal pachymetry at baseline versus White or Asian patients.

CONCLUSIONS

In this clinical cohort of patients with KCN from a tertiary referral center, Black patients were less likely to receive CXL presumably because of more advanced disease at presentation. Earlier active population screening may be indicated to identify and treat these patients before they become ineligible for treatment and develop irreversible vision loss. Such strategies may improve health equity in KCN management.

COVID-19 Testing and Vaccination Among US Older Adults with Vision Impairment: The National Health and Aging Trends Study 2021

PURPOSE

To examine the associations between vision impairment (VI) and COVID-19 testing and vaccination services in older US adults.

METHODS

This cross-sectional study assessed data from adults ≥ 65 years who participated in the National Health and Aging Trends Study (year 2021), a nationally representative sample of Medicare beneficiaries. Exposure: Distance VI (<20/40), near VI (<20/40), contrast sensitivity impairment (CSI) (<1.55 logCS), and any VI (distance, near, or CSI). Outcomes: Self-reported COVID-19 testing and vaccination.

RESULTS

Of 2,822 older adults, the majority were female (weighted; 55%) and White (82%), and 32% had any VI. In fully-adjusted regression analyses, older adults with any VI had similar COVID-19 vaccination rates to adults without any VI (OR:0.77, 95% CI:0.54-1.09), but had lower odds of COVID-19 testing (OR:0.82, 95% CI:0.68-0.97). Older adults with distance (OR:0.47, 95% CI:0.22-0.99) and near (OR:0.68, 95% CI:0.47-0.99) VI were less likely to be vaccinated for COVID-19, while those with CSI were less likely to test for COVID-19 (OR:0.76, 95% CI:0.61-0.95), as compared to peers without respective impairments. The remaining associations were not significant (p > .05).

CONCLUSIONS AND RELEVANCE

These findings highlight inequities in the COVID-19 pandemic response for people with vision disability and emphasize the need for equitable prioritization of accessibility of healthcare services for all Americans.

Racial Variation in Visual Impairment of Patients With Keratoconus at Presentation

PURPOSE

This study aimed to investigate racial disparities in the severity of keratoconus (KCN) at presentation, their intersection with socioeconomic variables, and other factors associated with visual impairment.

METHODS

This retrospective cohort study examined medical records of 1989 patients (3978 treatment-naive eyes) with a diagnosis of KCN seen at Wilmer Eye Institute between 2013 and 2020. A multivariable regression model adjusting for age, sex, race, insurance type, KCN family history, atopy, smoking status, and vision correction method examined factors associated with visual impairment, defined as a best available visual acuity of worse than 20/40 in the better eye.

RESULTS

Demographically, Asian patients were the youngest (33.4 ± 14.0 years) ( P < 0.001), and Black patients had the highest median area deprivation index (ADI) of 37.0 [interquartile range (IQR): 21.0-60.5] ( P < 0.001). Multivariable analysis showed a higher risk of visual impairment for Black (OR 2.25, 95% CI, 1.71-2.95) versus White patients. Medicaid (OR 2.59, 95% CI, 1.75-3.83) and Medicare (OR 2.48, 95% CI, 1.51-4.07) were also associated with a higher odds of visual impairment compared with private insurance, and active smokers were more likely to have visual impairment than those with no prior smoking history (OR 2.17, 95% CI, 1.42-3.30). Eyes of Black patients had the highest maximum keratometry (Kmax) (56.0 ± 11.0D) ( P = 0.003) and the lowest thinnest pachymetry (463.2 ± 62.5 µm) ( P = 0.006) compared with eyes of other races.

CONCLUSIONS

Black race, government-funded insurance, and active smoking were significantly associated with increased odds of visual impairment in adjusted analyses. Black race was also associated with higher Kmax and lower thinnest pachymetry, suggesting that Black patients have more severe disease at presentation.

STEM doctorate recipients with disabilities experienced early in life earn lower salaries and are underrepresented among higher academic positions

There is paucity of data examining disparities in salary and representation for disabled scientists, which is needed to advance inclusion and equity for people with disabilities in STEM. Using data from the 2019 Survey of Doctorate Recipients (United States, N = 1,148,817), we show that doctorate recipients working in Science, Technology, Engineering and Mathematics (STEM) with disabilities experienced early in life (at age <25 yr) earned US$10,580 less per year (95% CI: -$13,661, -$7,499) than non-disabled workers. In the subset of academic workers, doctorate recipients with early disabilities earned $14,360 less (95% CI: -$17,546, -$11,175) than those without disabilities. We observed an underrepresentation of academics with disabilities in higher faculty ranks (χ2: 647.2; P < 0.0001), among Deans/Presidents (χ2: 27.4; P = 0.0004) and among those with tenure (χ2: 525; P < 0.0001). These findings support a need to expand inclusion efforts, provide equal opportunities for career advancement and improve working conditions for people with disabilities in STEM.

Using Objective Vision Measures to Explore the Association of Vision Impairment With Cognition Among Older Adults in the United States

PURPOSE

To evaluate the association between vision impairment (VI) and cognitive function using objective measures.

DESIGN

Cross-sectional analysis with a nationally representative sample.

METHODS

The association between VI and dementia was investigated in a US population-based, nationally representative sample of Medicare beneficiaries, the National Health and Aging Trends Study (NHATS), a nationally representative sample of Medicare beneficiaries aged ≥65 years, using objective vision measures. Exposures included distance VI (>20/40), near VI (>20/40), contrast sensitivity impairment (CSI) (<1.55), any objective VI (distance and near visual acuity, or contrast), and self-reported VI. The main outcome measure was dementia status defined based on survey reports, interviews, and cognitive tests.

RESULTS

A total of 3026 adults were included in this study; the majority were female (55%) and White (82%). The weighted prevalence rates were 10% for distance VI, 22% for near VI, 22% for CSI, 34% for any objective VI, and 7% for self-reported VI. Across all measures of VI, dementia was more than twice as prevalent in adults with VI compared to their peers without (P < .001 for all). In adjusted models, all measures of VI were associated with higher odds of dementia (distance VI: OR 1.74, 95% CI 1.24-2.44; near VI: OR 1.68, 95% CI 1.29-2.18; CSI: OR 1.95, 95% CI 1.45-2.62; any objective VI: OR 1.83, 95% CI 1.43-2.35; self-reported VI: OR 1.86, 95% CI 1.20-2.89).

CONCLUSIONS

In a nationally representative sample of older US adults, VI was associated with increased odds of dementia. These results suggest that maintaining good vision and eye health may help preserve cognitive function in older age, although more research is needed to investigate the potential benefits of interventions that focus on vision and eye health on cognitive outcomes.

The Impact of Social Determinants of Health on Eye Care Utilization in a National Sample of People with Diabetes

PURPOSE

To evaluate the association of social determinants of health (SDoH) with eye care utilization among people with diabetes mellitus using the 2013-2017 National Health Interview Survey (NHIS).

DESIGN

Retrospective cross-sectional study.

PARTICIPANTS

Participants ≥ 18 years of age with self-reported diabetes.

METHODS

The SDoH in the following domains were used: (1) economic stability; (2) neighborhood, physical environment, and social cohesion; (3) community and social context; (4) food environment; (5) education; and (6) health care system. An aggregate SDoH score was calculated and divided into quartiles, with Q4 representing those with the highest adverse SDoH burden. Survey-weighted multivariable logistic regression models evaluated the association of SDoH quartile with eye care utilization in the preceding 12 months. A linear trend test was conducted. Domain-specific mean SDoH scores were calculated, and the performance of domain-specific models was compared using area under the curve (AUC).

MAIN OUTCOME MEASURE

Eye care utilization in the preceding 12 months.

RESULTS

Of 20 807 adults with diabetes, 43% had not used eye care. Greater adverse SDoH burden was associated with decrements in odds of eye care utilization (P < 0.001 for trend). Participants in the highest quartile of adverse SDoH burden (Q4) had a 58% lower odds (odds ratio [OR], 0.42; 95% confidence interval [CI], 0.37-0.47) of eye care utilization than those in Q1. The domain-specific model using economic stability had the highest performing AUC (0.63; 95% CI, 0.62-0.64).

CONCLUSIONS

Among a national sample of people with diabetes, adverse SDoH were associated with decreased eye care utilization. Evaluating and intervening upon the effects of adverse SDoH may be a means by which to improve eye care utilization and prevent vision loss.

Self-Reported Vision Impairment and Food Insecurity in the US: National Health Interview Survey, 2011-2018

PURPOSE

To determine if vision impairment (VI) is associated with food insecurity among the United States (US) adults.

METHODS

This is a cross-sectional study of US adults ≥18 years below a threshold of 150% poverty from the National Health Interview Survey (NHIS), years 2011-2018. Outcome measures included food insecurity status, based on response to the NHIS adult (10-item) food insecurity tool, either as a binary (food secure or insecure) or ordinal (high, marginal, low, and very low) variable. VI was defined as self-reported trouble seeing, even when wearing glasses or contact lenses. Multivariable logistic regression analyses adjusted for potential confounders examined associations between VI and food insecurity.

RESULTS

Participants (N = 62075) were majority female (57%), White (62%), and non-Hispanic (74%). Of them, 16% reported VI and 28% were food insecure. In fully adjusted logistic regression models, adults with VI had 216% higher odds (95% CI = 2.01-2.31) of being food insecure than adults without VI. Further, there was a dose-response relationship between VI and food insecurity noted in a multinomial model: VI predicted 159% higher risk of marginal food security (95% CI = 1.44-1.75), 197% higher risk of low food security (95% CI = 1.80-2.16), and 295% higher risk of very low food security (95% CI = 2.69-3.22), as compared to high food security.

CONCLUSION

VI is associated with food insecurity, increasingly so among adults with highest levels of food insecurity in this national sample of low-income US adults. This data highlights the need for targeted interventions to address and reduce the burden of food insecurity among US adults with VI.

The Impact of Social Determinants of Health on Vision Loss From Cataracts and Cataract Surgery Utilization in the United States-A National Health Interview Survey Analysis

PURPOSE

To investigate the association of social determinants of health (SDOH) factors and cataract-related outcomes disparities.

DESIGN

Cross-sectional, with a nationally representative sample.

METHODS

We used publicly available data from the 2008, 2016, and 2017 National Health Interview Survey data sets. Outcome measures included self-reported prevalence for ever been diagnosed with cataract, vision loss secondary to cataracts, and the likelihood of undergoing cataract surgery. Survey-weighted, multivariable logistic regression models, adjusted for age, race and ethnicity, and other relevant covariates, were used to examine the association between SDOH factors and cataract-related outcomes.

RESULTS

A total of 81,551 participants were included, who were predominantly between 18 and 44 years of age (49.6%), female (51.7%), and White (74.8%). Multivariable regression models with age as a covariate showed that individuals who were not working were more likely to report having cataracts than those who were working (P < .001). Those who needed but could not afford medical care in the past year were more likely to report vision loss secondary to cataracts than their counterparts (P < .001). Uninsured participants were less likely to report undergoing cataract surgery than those with private insurance (P = .03). Individuals with higher income (poverty-income ratio: 1.00-2.99 vs <1.00) were more likely to report undergoing cataract surgery (P = .04).

CONCLUSIONS

Several SDOH factors were associated with disparities in rates of cataract-related outcomes. These findings highlight the importance of ophthalmologists screening for social risks in patients with cataract, as these social factors are important barriers for access to care.

Disparities in Eye Care Utilization by Self-Reported Vision Difficulty and Diabetes Status in the United States

PURPOSE

To assess differences in eye care utilization by vision difficulty (VD), diabetes status, and sociodemographic characteristics for American adults.

METHODS

The analysis pooled cross-sectional data from the National Health Interview Survey (2010-2018) from US adults ≥ 18 years. The outcome measure was eye care utilization in the past year. The primary independent variable included four groups: no VD or diabetes, only diabetes, only VD, and diabetes and VD. VD was defined as self-reported difficulty seeing even with glasses or contacts. Diabetic status was defined as ever receiving this diagnosis by a health professional. Multivariable logistic regression analyses examined associations between eye care utilization, VD, diabetic status, and sociodemographic characteristics.

RESULTS

Of the 284,599 adults included in this study, the majority were female (55%), White (73%), and non-Hispanic (84%). In regression analysis, as compared to adults without diabetes or VD, adults with both diabetes and VD had the greatest utilization (OR = 2.49, 99% CI = 2.18-2.85). Females had higher utilization than men (OR = 1.45, 99% CI = 1.41-1.50). Higher levels of education was associated with greater utilization (OR = 1.82, 99% CI = 1.72-1.92). White and American Indian adults without diabetes had higher utilization compared to other races (OR = 1.17, 99% CI = 1.12-1.24, 0.98-1.39).

CONCLUSION

While adults with VD and diabetes are better connected to eye care, significant eye care disparities persist for marginalized groups in the U.S. Identifying and understanding these disparities and eliminating barriers to care is critical to better support all patient populations.

Vision difficulty and dementia: economic hardships among older adults and their caregivers

Introduction

Limited research has examined the economic impact of vision difficulty (VD) and dementia on older adults and their caregivers. We aimed to determine whether older adults with VD and/or dementia, and their caregivers, face more economic hardships than their counterparts without VD or dementia.

Methods

We used cross-sectional data from the 2015 National Health and Aging Trends Study (NHATS), a population-based survey of Medicare beneficiaries, linked to their family/unpaid caregivers from the National Study of Caregiving (NSOC). Regression models characterized the association of VD (self-report), dementia (survey and cognitive assessments), and co-occurring VD and dementia with debt, receiving financial help from relatives, government-based Supplemental Nutrition Assistance Program (SNAP), other food assistance, utility assistance, and caregiver financial difficulty.

Results

The NHATS sample included 6,879 community-dwelling older adults (5670 no VD/dementia, 494 VD-alone, 512 dementia-alone, 203 co-occurring VD and dementia). Adults with VD and dementia had higher odds of receiving SNAP benefits (OR = 2.6, 95%CI = 1.4-4.8) and other food assistance (OR = 4.1, 95%CI = 1.8-9.1) than adults without VD/dementia, while no differences were noted for debt, financial help, and utility assistance. Adults with VD-alone had higher odds of debt (OR = 2.1, 95%CI = 1.3-3.2), receiving financial help (OR = 1.7, 95%CI = 1.1-2.5) and other food assistance (OR = 2.7, 95%CI = 1.7-4.3); while adults with dementia-alone had higher odds of debt (OR = 2.8, 95%CI = 1.4-5.5). The NSOC sample included 1,759 caregivers (995 caring for adults without VD/dementia, 223 for VD-alone, 368 for dementia-alone, and 173 for co-occurring VD and dementia). Compared to caregivers of older adults without VD/dementia, caregivers of adults with VD and dementia had higher odds of financial difficulty (OR = 3.0, 95%CI = 1.7-5.3) while caregivers of adults with VD-alone or dementia-alone did not.

Discussion

While older adults with VD- or dementia-alone experienced increased economic hardships, disparities in food assistance were amplified among older adults with co-occurring disease. Caregivers of adults with co-occurring disease experienced more financial difficulty than caregivers of adults with a single or no disease. This study highlights the need for interventions across clinical and social services to support the economic wellbeing of our aging population and their caregivers.

Disparities in influenza vaccination for U.S. adults with disabilities living in community settings by race/ethnicity, 2016-2021

BACKGROUND

There is a paucity of data examining disparities in influenza vaccination at the intersection of disability and race.

OBJECTIVE

To compare the prevalence of influenza vaccination between U.S. adults (≥18 years) with and without disabilities living in community settings, and to examine changes in influenza vaccination over time by disability status and race/ethnicity groups.

METHODS

We analyzed cross-sectional data from the Behavioral Risk Factor Surveillance System (2016-2021). We calculated the annual age-standardized prevalence of influenza vaccination (last 12 months) in individuals with and without disabilities (2016-2021), and examined percentage changes (2016-2021) by groups of disability status and race/ethnicity.

RESULTS

From 2016 to 2021, the annual age-standardized prevalence of influenza vaccination was consistently lower in adults with disabilities as compared to those without disabilities. In 2016, 36.8% (95%CI: 36.1%-37.4%) of adults with disabilities had an influenza vaccine versus 37.3% (95%CI: 36.9%-37.6%) of those without disabilities. In 2021, 40.7% (95%CI: 40.0%-41.4%) and 44.1% (95%CI: 43.7%-44.5%) of adults with and without disabilities had an influenza vaccine. The percentage change in influenza vaccination from 2016 to 2021 was lower among people with disabilities (10.7%, 95%CI: 10.4%-11.0%; vs. no disability: 18.4%, 95%CI: 18.1%-18.7%). Among adults with disabilities, Asian adults reported the largest percentage increase in influenza vaccination (18.0%, 95% CI: 14.2%, 21.8%; p: 0.07), and Black, Non-Hispanics adults reported the lowest (2.1%, 95% CI: 1.9%, 2.2%; p: 0.59).

CONCLUSIONS

Strategies to increase influenza vaccination in the U.S. should address barriers faced by people with disabilities, particularly the intersectional barriers faced by people with disabilities from racial and ethnic minority groups.

Cataracts

94 million people are blind or visually impaired globally, and cataract is the most common cause of blindness worldwide. However, most cases of blindness are avoidable. Cataract is associated with decreased quality of life and reduced life expectancy. Most cases of cataract occur after birth and share ageing and oxidative stress as primary causes, although several non-modifiable and modifiable risk factors can accelerate cataract formation. In most patients, phacoemulsification with intraocular lens implantation is the preferred treatment and is highly cost-effective. There has been an increase in the use of comprehensive cataract surgical services, including diagnoses, treatment referrals, and rehabilitation. However, global inequity in surgical service quality is still a limitation. Implementation of preoperative risk assessment, risk reduction strategies, and new surgical technologies have made cataract surgery possible at an earlier stage of cataract severity with the expectation of good refractive outcomes. The main challenge is making the service that is currently available to some patients accessible to all by use of universal health coverage.

RACIAL DISPARITIES IN THE ASSOCIATION BETWEEN VISION IMPAIRMENT AND FOOD INSECURITY IN THE US

We examined racial disparities in household food insecurity among low-income Americans with and without vision impairment in the National Health Interview Survey, years 2011-2018. Among 257,620 U.S. adults below a threshold of 150% poverty, 15% of White, 16% of Black, and 8% of Asian Americans, and 18% of American Indians and Inuits reported vision impairment. In analyses adjusted for sociodemographic variables, vision impairment was associated with >100% greater odds (95% CI=2.01-2.31) of 30-day food insecurity, as compared to no vision impairment. Further, odds of household food insecurity were higher among Black Americans (OR=1.37, 95% CI=1.29-1.47), and American Indians and Inuits (OR=1.38, 95% CI=1.15-1.66) than White Americans, while Asians had lower odds (OR=0.45, 95 %CI=0.36-0.57). These findings highlight that low-income adults with vision impairment and racial minorities experience food disparities and dietary inadequacy, an area of disadvantage that can influence overall health, in a nationally representative sample in the U.S.

Accessibility and disability inclusion among top-funded U.S. Undergraduate Institutions

BACKGROUND

There is limited data to assess, track, or quantify accessibility and disability inclusion across universities.

OBJECTIVE

This cross-sectional study assessed disability inclusion and accessibility at the top 50 National Institutes of Health (NIH)-funded undergraduate programs in the United States. We hypothesized that there is no association between NIH funding and the University Disability Inclusion Score.

METHODS

A novel tool, the University Disability Inclusion Score assessed disability inclusion and accessibility using 10 indicators spanning 4 categories: (1) accessibility of built and virtual environment, (2) public image of disability inclusion, (3) accommodations processes and procedures, and (4) grievance policy. Based upon the total points (out of a total score of 100), each university was assigned a letter grade (A-F).

RESULTS

Of the top 50 NIH-funded institutions, 6% received an A grade on the Score, while 60% received D or F. The mean scores were 15.2 (SD = 5) for accessibility of built and virtual environment (20 points), 10 (SD = 3) for public image of disability inclusion (20 points), 30.6 (SD = 10) for accommodations processes and procedures (50 points), and 8.1 (SD = 3) for grievance policy (10 points).

CONCLUSIONS

Our findings suggest room for improvement in disability inclusion and accessibility among top university recipients of NIH funding. To provide an equitable academic experience, universities must prioritize disability inclusion.

Stigma Among Older Adults with Age-Related Vision Impairments

Introduction: Limited research has examined the experience and psychosocial effect of vision impairment in older adults. We examine the relationship between vision impairment and stigma using guided interviews among older adults with age-related eye disease. Methods: Thirty-six participants with vision impairment were recruited from glaucoma ( n = 18) (better eye visual fields mean deviations: >5 and <15 decibels) or retina ( n = 18) (better eye visual acuity: <20/40 and >20/400) clinics of the Johns Hopkins Wilmer Eye Institute between 2015 and 2020. Participants completed interviews to examine stigma surrounding age-related vision impairment. Interviews were transcribed and analyzed using directed content analysis. Results: Content analyses of interview transcripts revealed underlying stigma within our cohort. Starting with categories of (1) interpersonal relationships and (2) evolving self-perception, specific domains of stigma were realized in this study. Although both enacted (external) stigma and perceived stigma were acknowledged by a subset of participants, few endorsed internalized stigma. In the face of stigma, participants demonstrated notable resiliency in adapting to and living with age-related vision impairment, captured in an additional category of (3) behavioral adaptations. Discussion: In-depth interviews revealed that older adults with vision impairment confront specific domains of stigma, including enacted and perceived stigma. Features protective against internalized stigma included older age, community support, and assistive technologies. Implications for Practitioners: A recognition of the subtypes of stigma that older adults with age-related vision impairment face is necessary to tailor support and target interventions.

The development of the Supplemental Nutrition Assistance Program enrollment accessibility (SNAP-access) score

BACKGROUND

The Supplemental Nutrition Assistance Program (SNAP) is a federal public benefit providing food assistance to millions of Americans. However, it is typically administered by states, creating potential variation in accessibility and transparency of information about enrollment for people with disabilities.

OBJECTIVE

To develop and demonstrate the use of a method to assess the accessibility and transparency of information about the disability-inclusive process and practices of SNAP enrollment.

METHODS

Cross-sectional data was collected from SNAP landing and enrollment webpages from all 50 U.S. states, the District of Columbia, and New York City from June-August 2021. Based on principles of universal design and accessibility, scores were determined for each SNAP program across three areas: flexibility in the enrollment process (6 points), efficiency of finding information about enrollment on SNAP websites (6 points), and the accessibility of SNAP webpages (6 points). Total scores were the sum of these sub-categories (18 points maximum).

RESULTS

Of the 52 SNAP programs assessed, mean scores were 10.66 (SD = 2.51) for the total score, 2.67 (SD = 0.91) for flexibility in the enrollment process, 3.32 (SD = 1.19) for efficiency of finding information about enrollment on SNAP websites, and 4.67 (SD = 1.72) for the accessibility of SNAP webpages. No programs received the maximum flexibility score (6 points) on flexibility, 2 programs received the maximum on efficiency, and 31 programs the maximum on accessibility.

CONCLUSIONS

We found differences in the accessibility, flexibility, and efficiency of SNAP program enrollment information available on SNAP websites and outline room for improvement across all three of these areas.

Labor Force Participation and Hearing Loss Among Adults in the United States: Evidence From the National Health and Nutrition Examination Survey

PURPOSE

The purpose of this article was to study the association between hearing loss (HL) and labor force participation in the National Health and Nutrition Examination Survey (NHANES).

METHOD

This cross-sectional study used data from the 1999-2000, 2001-2002, 2003-2004, 2011-2012, and 2015-2016 cycles of the NHANES. The sample was restricted to adults aged 25-65 years with complete audiometric data. HL was defined based on the pure-tone average (PTA) of 0.5-, 1-, 2-, and 4-kHz thresholds in the better hearing ear as follows: no loss (PTA < 25 dB), mild HL (25 dB < PTA < 40 dB), and moderate-to-severe HL (PTA > 40 dB). The association between HL and labor force participation was estimated using weighted logistic regression adjusted for age, sex, race/ethnicity, education, living arrangements, and health status.

RESULTS

In a sample of 9,963 participants (50.6% women, 22.6% Black, 27% Hispanic), we found that compared with adults without HL, individuals with moderate-to-severe HL had greater odds of being outside of the labor force (odds ratio = 2.35; 95% confidence interval: 1.42-3.88). However, there were no differences by HL status in being employed or having a full- versus part-time job.

CONCLUSIONS

Moderate-to-severe HL, but not mild HL, was associated with higher odds of not participating in the labor force. However, there were no differences by HL status in being employed or having a full- versus part-time job. Further research is needed to better characterize how HL may affect labor force participation.

COVID-19 Vaccine Website Accessibility Dashboard

Background

The COVID-19 pandemic has exacerbated historical inequities for people with disabilities including barriers in accessing online information and healthcare appointment websites. These barriers were brought to the foreground during the vaccine rollout and registration process.

Objective

This cross-sectional study aimed to examine accessibility of U.S. state and territory COVID-19 information and registration centralized websites.

Methods

The Johns Hopkins Disability Health Research Center created a COVID-19 Vaccine Dashboard compiling COVID-19 information and vaccine registration web pages from 56 states and territories in the United States (U.S.) reviewed between March 30 through April 5, 2021 and analyzed accessibility using WAVE Web Accessibility Evaluation Tool (WAVE). WAVE identifies website accessibility barriers, including insufficient contrast, alternative text, unlabeled buttons, total number of errors, and error density. Web pages were ranked and grouped into three groups by number of errors, creating comparisons between states on accessibility barriers for people with disabilities.

Results

All 56 U.S states and territories had COVID-19 information web pages and 29 states had centralized state vaccine registration web pages. Total errors, error density, and alert data were utilized to generate accessibility scores for each web page, the median score was 259 (range = 14 to 536 and IQR = 237) for information pages, and 146 (range = 10 to 281 and IQR = 105) for registration pages.

Conclusions

These results highlight barriers people with disabilities may encounter when accessing information and registering for the COVID-19 vaccine, which underscore inequities in the pandemic response for the disability community and elevate the need to prioritize accessibility of public health information.

Identifying Accessibility Requests for Patients With Disabilities Through an Electronic Health Record-Based Questionnaire

IMPORTANCE

People with disabilities experience disparities in health care access and outcomes, and inaccessible health care facilities are major barriers to health care access. Methods to collect accessibility request information are needed to improve health care outcomes for patients with disabilities.

OBJECTIVE

To evaluate an electronic health record (EHR)-based questionnaire designed to identify accessibility requests for patients with disabilities at an eye clinic.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional pilot study implemented an EHR questionnaire and prospectively collected data on accessibility requests at a university-based eye clinic. The study included 55 722 patients making appointments at the Johns Hopkins Wilmer Eye Institute from April 1, 2019, to March 31, 2020.

MAIN OUTCOMES AND MEASURES

The Wilmer Eye Institute staff were trained to assess accessibility requests of patients making appointments in-person or via telephone using a standardized script and entering patient responses into the EHR. Data were later extracted for analysis and used to determine the proportion of patients making eye appointments who reported a disability accessibility request (physical, sensory, or intellectual) during their clinic visit.

RESULTS

Accessibility request data were collected from 250 932 patient encounters. Patients had a mean (SD) age of 61.9 (20.6) years; most were women (146 846 [58.5%]) and were White individuals (162 720 [64.9%]). Of these, 23 510 (9.4%) encounters were associated with an accessibility request. The most reported accessibility request was mobility related (18 857 [7.5%]) (needing a cane, crutches, motorized scooter, walker, wheelchair, stretcher, assistance standing, or transport services), followed by sensory-related (2988 [1.2%]) (visual, hearing, or speech impairment), intellectual (353 [0.1%]), and other (1312 [0.5%]) (assistance with filling forms or service animal) requests. Patients with an accessibility request compared with those without, were older (72.6 vs 60.8 years), less likely to be White individuals (59.7% vs 65.4%), and more likely to be women (62.6% vs 58.1%), receiving Medicare (69.6% vs 41.5%), and have vision impairment (41.3% vs 13.6%) (P < .001 for all).

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, a substantial proportion of patients making eye appointments reported having accessibility requests as captured using a new EHR-based questionnaire. Such standardization of data collection for disability-related accessibility requests in EHR is scalable, could be expanded to other clinical settings, and has the potential to improve accessibility of health care interactions for patients with disabilities.

Predicting subjective refraction with dynamic retinal image quality analysis

The aim of this work is to evaluate the performance of a novel algorithm that combines dynamic wavefront aberrometry data and descriptors of the retinal image quality from objective autorefractor measurements to predict subjective refraction. We conducted a retrospective study of the prediction accuracy and precision of the novel algorithm compared to standard search-based retinal image quality optimization algorithms. Dynamic measurements from 34 adult patients were taken with a handheld wavefront autorefractor and static data was obtained with a high-end desktop wavefront aberrometer. The search-based algorithms did not significantly improve the results of the desktop system, while the dynamic approach was able to simultaneously reduce the standard deviation (up to a 15% for reduction of spherical equivalent power) and the mean bias error of the predictions (up to 80% reduction of spherical equivalent power) for the handheld aberrometer. These results suggest that dynamic retinal image analysis can substantially improve the accuracy and precision of the portable wavefront autorefractor relative to subjective refraction.

Concerns on healthcare access, utilization and safety due to COVID-19 among American adults with vision loss

Background

Limited studies have indicated that Americans with vision loss are differentially impacted by COVID-19.

Objective

We examined concerns with healthcare and safety among Americans with vision loss during the early phase of the pandemic (April 2020).

Methods

The Flatten Inaccessibility Survey assessed the impact of COVID-19 on healthcare (pharmacy access, maintenance of eyecare regimen, caregiver access, and resource denial) and safety (social distancing, clean surfaces, and touching public signage) concerns among Americans with low vision or who were blind. Multivariable logistic regression was used to determine associations between respondent characteristics and each concern.

Results

A total of 1921 adults responded to the survey, of whom 65% were blind and 35% had low vision. Most respondents were female (63%) and white (74%). Respondents with additional disabilities/comorbidities were more likely to report healthcare access concerns (pharmacy access, eyecare regimen, caregiver access, and ventilator access) and safety concerns (social distance, clean surfaces, and touching signage) than those with vision loss alone. In addition, females, those identifying as “other” gender, older individuals, and people with adult onset of vision impairment were more likely to experience COVID-19–related concerns and challenges related to healthcare and overall safety.

Conclusion

These results suggest that while Americans with vision loss have been differentially impacted by COVID-19, adults with vision loss and additional disabilities/comorbidities are more likely to have concerns with healthcare and safety than those with vision loss alone.

Vision impairment and cognitive decline among older adults: a systematic review

OBJECTIVES

There has been increasing epidemiological research examining the association between vision impairment (VI) and cognitive impairment and how poor vision may be a modifiable risk factor for cognitive decline. The objective of this systematic review is to synthesise the published literature on the association of VI with cognitive decline, cognitive impairment or dementia, to aid the development of interventions and guide public policies pertaining to the relationship between vision and cognition.

METHODS

A literature search was performed with Embase, Medline and Cochrane library databases from inception to March 2020, and included abstracts and articles published in peer-reviewed journals in English. Our inclusion criteria included publications that contained subjective/objective measures of vision and cognition, or a diagnosis of VI, cognitive impairment or dementia. Longitudinal or cross-sectional studies with ≥100 participants aged >50 years were included. The search identified 11 805 articles whose abstracts underwent screening by three teams of study authors. Data abstraction and quality assessment using the Effective Public Health Practice Project Quality Assessment Tool were performed by one author (NN). 10% of the articles underwent abstraction and appraisal by a second author (LA/VV), results were compared between both and were in agreement.

RESULTS

110 full-text articles were selected for data extraction, of which 53 were cross-sectional, 43 longitudinal and 14 were case-control studies. The mean age of participants was 73.0 years (range 50-93.1). Ninety-one (83%) of these studies reported that VI was associated with cognitive impairment.

CONCLUSION

Our systematic review indicates that a majority of studies examining the vision-cognition relationship report that VI is associated with more cognitive decline, cognitive impairment or dementia among older adults. This synthesis supports the need for additional research to understand the mechanisms underlying the association between VI and cognitive impairment and to test interventions that mitigate the cognitive consequences of VI.

Working while Caring for Older Adults with Hearing Impairment and Dementia: Evidence from the NSOC

Age-related hearing loss (HL) and dementia are common among older adults. The implications of caregiving for older adults with dementia is documented. Whether the presence of HL modifies these association is unknown. We used data from the 2011 NHATS/NSOC. Hearing loss and dementia were identified among care recipients (CR). Our outcomes included: hours of care provided, and caregiver’s work activities. Among 1,013 caregivers, 456 assisted individuals without HL or dementia (HL-/D-), 229 with dementia (D+), 193 with HL, and 135 with HL and dementia (HL+/D+). In fully adjusted models, as compared to caregivers of HL-/D-, caregivers of D+ spent 39.1 hours more (95% CI: 13.6,64.6) in caregiving, caregivers of HL+/D+ spent 56.6 more hours (95% CI: 25.1,88.1). We found no differences in work activities between CR groups. The presence of HL increases the caregiving needs of adults with dementia. The additional time does not affect the labor participation of caregivers.

Predictors of Receiving Keratoplasty for Keratoconus

PURPOSE

To identify sociodemographic factors and comorbid conditions associated with receiving keratoplasty for keratoconus (KCN).

DESIGN

Retrospective, cross-sectional study.

METHODS

Health records of KCN patients <65 years of age from 2011 to 2018 were obtained from the IBM MarketScan Database. A multivariable model adjusted for potential confounders was used to examine factors associated with the risk of receiving keratoplasty.

RESULTS

Of 42,086 total patients with KCN identified, 1282 (3.0%) patients had keratoplasty to treat KCN. In the fully adjusted analysis, female sex (odds ratio [OR] 0.87 [95% confidence interval {CI} 0.78-0.98]) and living in metropolitan areas (OR 0.75 [95% CI 0.63-0.90]) were associated with lower odds of receiving keratoplasty. Compared with individuals 10 to 19 years of age, those 20 to 29 years of age (OR 1.77 [95% CI 1.31-2.41]) and 30 to 39 years of age (OR 1.61 [95% CI 1.19-2.17]) were more likely to have keratoplasty, while individuals in the older age groups (50-64 years of age) did not show statistically significant associations. Conditions associated with higher odds of receiving keratoplasty were corneal hydrops (OR 4.87 [95% CI 4.07-5.82]), Leber congenital amaurosis (OR 2.41 [95% CI 1.02-5.71]), sleep apnea (OR 1.46 [95% CI 1.25-1.71]), diabetes mellitus (OR 1.32 [95% CI 1.13-1.54]), and depression (OR 1.22 [95% CI 1.03-1.44]). Conditions associated with lower odds were previous contact lens usage (OR 0.61 [95% CI 0.50-0.74]) and a history of glaucoma (OR 0.60 [95% CI 0.49-0.73]).

CONCLUSIONS

This analysis of a large sample of patients with KCN reveals previously unidentified risk factors associated with receiving keratoplasty including Leber congenital amaurosis, depression, and diabetes. Future research should examine if young patients with these conditions may benefit from more frequent follow-up and/or early crosslinking to reduce the need for subsequent keratoplasty.

National Prevalence of Disability and Disability Types Among Adults in the US, 2019

This cross-sectional study uses data from the 2019 Behavioral Risk Factor Surveillance System to examine the most recent estimates of disability prevalence among adults in the US.

Caring for Older Adults With Self-Reported Vision Impairment: Findings from the National Study of Caregiving

PURPOSE

The purpose of this study was to examine caregiving relationships for older adults with vision impairment (VI).

DESIGN

Cross-sectional study with a nationally representative sample.

METHODS

Setting: the National Health and Aging Trends Study linked to the National Study of Caregiving, Year 2011.

STUDY POPULATION

1,776 family or unpaid caregivers to community-dwelling Medicare beneficiaries age ≥65 years old.

OUTCOME MEASUREMENT

in the preceding month, 1) the number of hours of care provided; 2) the valued activities affected by caregiving; and 3) the odds of experiencing substantial emotional, financial, and physical difficulty related to providing care.

EXPOSURE

VI was defined as a report of blindness or difficulty with distance or near vision.

RESULTS

Among 1,776 caregivers, 428 caregivers spent an average ± standard error (SE) of 111 ± 9.1 hours per month assisting older adults with VI, whereas 1,348 spent an average of 72 ± 3.3 hours assisting older adults without VI. In fully adjusted negative binomial regression analyses, caregivers of older adults with VI spent 36% more hours (incident rate ratio [IRR]: 1.36; 95% confidence interval [CI]: 1.15-1.60) providing care and reported having 61% more valued activities affected (IRR: 1.61; 95% CI: 1.23-2.10) than caregivers of older adults without VI. In fully adjusted logistic regression analyses, caregivers of older adults with VI had greater odds of emotional (odds ratio [OR]: 1.46; 95% CI: 1.04-2.03) but not financial (OR: 1.33; 95% CI: 0.87-2.03) or physical (OR: 1.13; 95% CI: 0.74-1.74) difficulty related to providing care than caregivers of older adults without VI.

CONCLUSIONS

These results suggest that caring for older adults with VI places different demands on time and emotional wellbeing than caring for older adults without VI, but no differences in financial or physical difficulties.

Association of Vision Impairment With Cognitive Decline Across Multiple Domains in Older Adults

IMPORTANCE

Associations between visual and global cognitive impairments have been previously documented, but there is limited research examining these associations between multiple measures of vision across cognitive domains.

OBJECTIVE

To examine the association between vision and cognitive across multiple cognitive domains using multiple measures of vision.

DESIGN, SETTING, AND PARTICIPANTS

This longitudinal cohort study used data from the Baltimore Longitudinal Study of Aging for 2003 to 2019. Participants in the current study were aged 60 to 94 years with vision and cognitive measures. Data analysis was performed from May 2020 to May 2021.

MAIN OUTCOMES AND MEASURES

Cognitive function was measured across multiple domains, including language, memory, attention, executive function, and visuospatial ability. Cognitive domain scores were calculated as the mean of standardized cognitive test scores within each domain. Visual function was assessed using measures of visual acuity, contrast sensitivity, and stereo acuity at baseline.

RESULTS

Analyses included 1202 participants (610 women [50.8%]; 853 White participants [71.0%]) with a mean (SD) age of 71.1 (8.6) years who were followed up for a mean (SD) of 6.9 (4.7) years. Worse visual acuity (per 0.1 logarithm of the minimal angle of resolution) at baseline was associated with greater declines in language (β, -0.0035; 95% CI, -0.007 to -0.001) and memory (β, -0.0052; 95% CI, -0.010 to -0.001) domain scores. Worse contrast sensitivity (per 0.1 log units) at baseline was associated with greater declines in language (β, -0.010; 95% CI, -0.014 to -0.006), memory (β, -0.009; 95% CI, -0.015 to -0.003), attention (β, -0.010; 95% CI, -0.017 to -0.003), and visuospatial ability (β, -0.010; 95% CI, -0.017 to -0.002) domain scores. Over the follow-up period, declines on tests of language (β, -0.019; 95% CI, -0.034 to -0.005) and memory (β, -0.032; 95% CI, -0.051 to -0.012) were significantly greater for participants with impaired stereo acuity compared with those without such impairment.

CONCLUSIONS AND RELEVANCE

These findings suggest that the association between vision and cognition differs between visual acuity, contrast sensitivity, and stereo acuity and that patterns of cognitive decline may differ by type of vision impairment, with impaired contrast sensitivity being associated with declines across more cognitive domains than other measures of visual functioning.

Investigation of the Accuracy of a Low-Cost, Portable Autorefractor to Provide Well-Tolerated Eyeglass Prescriptions: A Randomized Crossover Trial

PURPOSE

To compare patient preferences for eyeglasses prescribed using a low-cost, portable wavefront autorefractor versus standard subjective refraction (SR).

DESIGN

Randomized, cross-over clinical trial.

PARTICIPANTS

Patients aged 18 to 40 years presenting with refractive errors (REs) to a tertiary eye hospital in Southern India.

METHODS

Participants underwent SR followed by autorefraction (AR) using the monocular version of the QuickSee device (PlenOptika Inc). An independent optician, masked to the refraction approach, prepared eyeglasses based on each refraction approach. Participants (masked to refraction source) were randomly assigned to use SR- or AR-based eyeglasses first, followed by the other pair, for 1 week each. At the end of each week, participants had their vision checked and were interviewed about their experience with the eyeglasses.

MAIN OUTCOME MEASURES

Patients preferring eyeglasses were chosen using AR and SR.

RESULTS

The 400 participants enrolled between March 26, 2018, and August 2, 2019, had a mean (standard deviation) age of 28.4 (6.6) years, and 68.8% were women. There was a strong correlation between spherical equivalents using SR and AR (r = 0.97, P < 0.001) with a mean difference of -0.07 diopters (D) (95% limits of agreement [LoA], -0.68 to 0.83). Of the 301 patients (75.2%) who completed both follow-up visits, 50.5% (n = 152) and 49.5% (n = 149) preferred glasses prescribed using SR and AR, respectively (95% CI, 45.7-56.3; P = 0.86). There were no differences in demographic or vision characteristics between participants with different preferences (P > 0.05 for all).

CONCLUSIONS

We observed a strong agreement between the prescriptions from SR and AR, and eyeglasses prescribed using SR and AR were equally preferred by patients. Wider use of prescribing based on AR alone in resource-limited settings is supported by these findings.

Vision Impairment and Participation in Cognitively Stimulating Activities: The Health ABC Study

BACKGROUND

Engagement in cognitively stimulating activities is associated with decreased rates of cognitive decline in older adults. However, most cognitively stimulating tasks require good vision, potentially affecting the ability of visually impaired adults to engage in these activities. We examined the relationship between vision and participation in cognitively stimulating activities.

METHOD

Data from the Health, Aging, and Body Composition study (1999-2005) were analyzed. Associations between visual function (visual acuity [VA], contrast sensitivity [CS], and stereo acuity [SA] impairments) and annual rates of change in number of cognitively stimulating activities (by self-report) performed at least once a month were examined.

RESULTS

Analyses included 924 participants aged 75.2 ± 2.8 years. At baseline, impaired CS (27%) and SA (29%) were associated with participation in fewer cognitive activities (β = -0.33, 95% CI = -0.63, -0.03 and β = -0.32, 95% CI = -0.61, -0.03, respectively), while VA (8%) was not (β = -0.34, 95% CI = -0.81, 0.13). In longitudinal models, groups with and without VA, CS, and SA impairments exhibited declines in monthly cognitive activities over time. Annual rates of decline were relatively higher in the VA (β = -0.16, 95% CI = -0.26, -0.05) and CS (β = -0.14, 95% CI = -0.19, -0.09) impaired groups than observed in the respective unimpaired groups (no VA: β = -0.12, 95% CI = -0.15, -0.10; no CS: β = -0.12, 95% CI = -0.15, -0.09), but did not achieve statistical significance. Stereo acuity (β = -0.13, 95% CI = -0.17, -0.09) and no SA (β = -0.13, 95% CI = -0.16, -0.10) groups had similar rates of decline.

CONCLUSIONS

Visually impaired older adults participate in fewer cognitive activities and although participation decline is similar to the non-impaired, lower overall participation indicates a need to identify cognitively stimulating activities accessible to visually impaired older adults.

Aging With Vision Loss: A Framework for Assessing the Impact of Visual Impairment on Older Adults

There is limited research examining the impact of visual impairment (VI) on older adults while considering the complexities of aging, leaving gaps in our understanding of how health consequences of VI might be averted. We created a framework integrating concepts from disability, geriatrics, and ophthalmology that conceptualizes how VI challenges successful aging. Here, VI influences multiple functional domains, and increases the risk of negative health outcomes. This model acknowledges that common causes, such as risk factors that affect eyes and other systems simultaneously, may also drive the relationship between VI and health outcomes. Finally, the model highlights how the impact of VI on aging outcomes can be addressed at multiple intervention points.

New obstacles and widening gaps: A qualitative study of the effects of the COVID-19 pandemic on U.S. adults with disabilities

BACKGROUND

Prior research has demonstrated that the needs of the disability community have not been met during public health emergencies. The COVID-19 pandemic has exacerbated existing inequities for many populations including people with disabilities, and data is needed to develop inclusive public health response policies.

OBJECTIVE

To identify how COVID-19 has uniquely impacted the lives of adults with disabilities.

METHODS

38 participants were recruited through disability advocacy groups and social media. Semi-structured virtual focus groups were conducted with adults (≥18 years) who self-identified as having a disability. Focus groups were conducted for each of six disability sub-groups: vision, hearing, mobility and physical, mental health, cognitive, intellectual, and developmental, and chronic illness. Using inductive coding, major themes were identified and compared across the disability sub-groups.

RESULTS

Three major themes and thirteen sub-themes were identified from the focus groups. The three major themes comprised: new problems created by the pandemic, obstacles in daily life that were exacerbated by the pandemic, and broader changes to accessibility and disability identity. Sub-themes such as difficulty with COVID-19 testing and regular medical care were reported by participants of all disability sub-groups, while other sub-themes like direct care needs and medical rationing were reported by participants from a subset of the disability sub-groups.

CONCLUSIONS

These results indicate how the COVID-19 pandemic unequally impacts disabled people. The participants indicated that to fully address their needs, disability perspectives must be included in the public health pandemic response. As new research shows that COVID-19 can cause long-term disability, the urgency to ensure the disability community is part of public health policies will increase.

The Bidirectional Relationship between Vision and Cognition: A Systematic Review and Meta-analysis

TOPIC

Visual impairment (VI) and cognitive impairment (CIM) are prevalent age-related conditions that impose substantial burden on the society. Findings on the hypothesized bidirectional association of VI and CIM remains equivocal. Hence, we conducted a systematic review and meta-analysis to examine this bidirectional relationship.

CLINICAL RELEVANCE

Sixty percent risk of CIM has not been well elucidated in the literature. A bidirectional relationship between VI and CIM may support the development of strategies for early detection and management of risk factors for both conditions in older people.

METHODS

PubMed, Embase, and Cochrane Central registers were searched systematically for observational studies, published from inception until April 6, 2020, in adults 40 years of age or older reporting objectively measured VI and CIM assessment using clinically validated cognitive screening tests or diagnostic evaluation. Meta-analyses on cross-sectional and longitudinal associations between VI and CIM outcomes (any CIM assessed using screening tests and clinically diagnosed dementia) were examined. Random effect models were used to generate pooled odds ratios (ORs) and 95% confidence intervals (CIs). We also examined study quality, publication bias, and heterogeneity.

RESULTS

Forty studies were included (n = 47 913 570). Meta-analyses confirmed that persons with VI were more likely to have CIM, with significantly higher odds of: (1) any CIM (cross-sectional: OR, 2.38 [95% CI, 1.84-3.07]; longitudinal: OR, 1.66 [95% CI, 1.46-1.89]) and (2) clinically diagnosed dementia (cross-sectional: OR, 2.43 [95% CI, 1.48-4.01]; longitudinal: OR, 2.09 [95% CI, 1.37-3.21]) compared with persons without VI. Significant heterogeneity was explained partially by differences in age, sex, and follow-up duration. Also, some evidence suggested that individuals with CIM, relative to cognitively intact persons, were more likely to have VI, with most articles (8/9 [89%]) reporting significantly positive associations; however, meta-analyses on this association could not be conducted because of insufficient data.

DISCUSSION

Overall, our work suggests that VI is a risk factor of CIM, although further work is needed to confirm the association of CIM as a risk factor for VI. Strategies for early detection and management of both conditions in older people may minimize individual clinical and public health consequences.

Association of Vision Impairment With Preventive Care Use Among Older Adults in the United States

Importance

Preventive care is associated with decreased morbidity and mortality among older adults. Vision impairment may be a barrier to accessing care and health promotion information and therefore may contribute to decreased preventive care uptake.

Objective

To examine the association between self-reported vision impairment and uptake of preventive care services (ie, breast and colon cancer screenings and influenza and pneumococcal vaccinations).

Design, Setting, and Participants

Cross-sectional study using the 2015 and 2018 National Health Interview Survey (NHIS) and 2016 and 2018 Behavioral Risk Factor Surveillance System (BRFSS) data, national surveys of US residents conducted through in-person household interviews in NHIS, and state-based telephone interviews in BRFSS. Participants included respondents 50 years and older based on eligibility for each preventive care service examined.

Exposures

Vision impairment, defined as self-reported trouble seeing, in NHIS, and self-reported blindness/serious difficulty seeing in BRFSS.

Main Outcomes and Measures

Self-reported uptake of breast cancer screening (women aged 50-74 years), colon cancer screening (aged 50-74 years), influenza vaccination (50 years and older), and pneumococcal vaccination (65 years and older). Multivariable regression models adjusted for relevant confounders, including age, were used to examine the uptake of each preventive care service by vision impairment status.

Results

Among NHIS participants, older US individuals with vision impairment (prevalence between 14.3% and 16.3% in the different age groups; n = 12 120-29 654) were less likely to report breast cancer screening (odds ratio [OR], 0.82; 95% CI, 0.71-0.96) and colon cancer screening (OR, 0.89; 95% CI, 0.79-0.99) but not influenza (OR, 1.06; 95% CI, 0.97-1.15) and pneumococcal vaccination (OR, 1.03; 95% CI, 0.91-1.16), as compared with their counterparts without vision impairment. In BRFSS (n = 228 649-530 027), those with vision impairment (5.9%-6.8%) were less likely than those without vision impairment to report breast cancer screening (OR, 0.67; 95% CI, 0.59-0.75), colon cancer screening (OR, 0.70; 95% CI, 0.65-0.76), and pneumococcal vaccination (OR, 0.89; 95% CI, 0.81-0.99) but not influenza vaccination (OR, 0.95; 95% CI, 0.89-1.00).

Conclusions and Relevance

Older Americans with vision impairment may be less likely to use cancer-related preventive services as compared with their counterparts without vision impairments. These findings suggest that interventions to improve access to health information and health care services for individuals with vision impairment may be needed to improve cancer screening among this population.

Vision Measures in Aging Cohorts: Gaps and Opportunities

There is wide variation in the methods used to assess vision across existing aging cohort studies. While subjective vision measures are valuable in capturing individuals’ perspectives, objective criteria are often needed to fully characterize visual impairment in older adults. In addition, visual function extends beyond acuity; contrast sensitivity, visual fields, and depth perception are known to impact daily functioning, and are needed to comprehensively assess visual function. Broader uptake of subjective and objective vision measures, and harmonization of vision measures across datasets is needed to robustly examine the role of visual impairment on aging and health outcomes. In this presentation, we will draw on work using data from the National Health and Aging Trends Study, Health and Retirement Study, and Health, Aging and Body Composition Study, among others, to illustrate uses of vision data in aging cohort studies, and examine the gaps and opportunities for improvement in vision measures.

The Association of Vision, Hearing, and Dual Sensory Impairments With Walking Speed and Incident Slow Walking

Vision (VI), hearing (HI) and dual sensory (DSI, concurrent VI and HI) impairments are increasing in prevalence as populations age. Walking speed is an established health indicator associated with adverse outcomes, including mortality. Using the population-based Health and Retirement Study, we analyzed the longitudinal relationship between sensory impairment and walking speed. In multivariable mixed-effects linear models, we found differences in baseline walking speed (m/s) by sensory impairment: Beta=-0.05 (95%CI=-0.07, -0.04), Beta=-0.02 (95%CI=--0.03, -0.003), and Beta=-0.07 (95%CI=--0.08, -0.05) for VI, HI and DSI, respectively, as compared to those without sensory impairment. However, similar annual declines (0.014 m/s) in walking speeds occurred in all groups. In time-to-event analyses, events were defined as “slow walking” (speed <0.60m/s) and “very slow walking” (<0.40m/s). Incident “slow walking” was 43% (95%CI=25%, 65%), 29% (95%CI=13%, 48%) and 35% (95%CI=13%, 61%) greater in VI, HI and DSI, respectively, than the no sensory impairment group, while incident “very slow walking” was 21% (95%CI=-4%, 54%), 30% (95%CI=3%, 63%) and 89% (95%CI=47%, 143%) greater; the increase was significantly greater in DSI than VI and HI. These results suggest that older adults with vision and hearing impairments walk slower and are at increased risk of slow walking than older adults without these sensory impairments. Additionally, older adults with DSI are at greatest risk of very slow walking.

World Health Report on Vision: Aging Implications for Global Vision and Eye Health

In 2019, the World Health Organization World Report on Vision estimated that that 2.2 billion people have a vision impairment, of which almost half could have been prevented or is yet to be addressed. As the global population ages and the prevalence of visual impairment increases, inequities in eye care and the downstream health and aging consequences of vision loss will become magnified. This session will: (1) provide key information regarding the burden of eye disease and visual impairment among older adults worldwide; (2) outline a framework created to conceptualize the aging and long-term health implications of vision loss, and (3) discuss the global public health challenges to eye care and to maximizing health for older adults with visual impairments.

Caring for Older Adults with Vision Impairment and Dementia: Data from the National Study of Caregiving

We examined caregiving relationships for individuals with vision impairment (VI) and dementia, using 2011 National Health and Aging Trends Study (NHATS) data, a survey of Medicare beneficiaries, linked to the National Study of Caregiving, a survey of family/unpaid helpers to NHATS participants. VI was defined as self-reported blindness or difficulty recognizing someone across the street, watching television or reading newspaper print. Dementia was defined as probable dementia based on survey-report or AD8 criteria. Caregiving outcomes included: (1) hours of care provided in the last month and (2) number of valued activities affected by caregiving. Among 1,196 caregivers, 617 assisted older adults without dementia or VI (D-/VI-), 298 with dementia but without VI (D+/VI-), 143 without dementia but with VI (D-/VI+), and 138 with dementia and VI (D+/VI+). In fully-adjusted regression models, caregivers of older adults D+/VI+ spent twice as many hours (IRR=2.0; 95%CI: 1.5-2.7) providing care than caregivers of older adults D-/VI-; however, caregivers of adults D+/VI- and those providing to older adults D-/VI+ spent 1.5-times more hours (95% CI=1.2-1.7; 95% CI=1.1-2.0, respectively). Additionally, caregivers of older adults D+/VI+ reported 4 times as many valued activities were affected (95%CI=2.8-5.6) then caregivers of those D-/VI-, while caregivers of those D+/VI- reported 1.9-times (95% CI=1.3-2.8) and D-/VI+ 1.6-times (95% CI=1.1-2.3) more activities were affected. Our results suggest that caring for older adults with VI has similar demands as caring for older adults with dementia, but that these implications may be magnified when caring for older adults with both dementia and VI.

Evaluation of Tablet-Based Tests of Visual Acuity and Contrast Sensitivity in Older Adults

Purpose: Recent innovations in mobile technology for the measurement of vision present a valuable opportunity to measure visual function in non-clinical settings, such as in the home and in field-based surveys. This study evaluated agreement between a tablet-based measurement of distance and near acuity and contrast sensitivity as compared to gold-standard clinical tests.Methods: Participants aged ≥55 years recruited from a tertiary eye clinic underwent testing with three tablet-based and corresponding gold-standard clinical measures (ETDRS distance acuity, Pelli-Robson contrast sensitivity, and MNRead near acuity). Correlation and agreement between tablet-based and clinical tests were assessed.Results: A total of 82 participants with a mean age of 69.1 (SD = 7.6) years, and majority female (67.1%) and white (64.6%), were enrolled in this study. The mean (SD) difference between the tests (gold-standard - tablet) was -0.04 (0.08) logMAR for distance acuity, -0.11 (0.13) log units for contrast sensitivity, and -0.09 (0.12) logMAR for near acuity. 95% limits of agreement for distance acuity (-0.21, 0.12 logMAR), near acuity (-0.34, 0.14 logMAR), and contrast sensitivity (-0.36, 0.14 logCS) were also determined. The correlation between tablet-based and gold-standard tests was strongest for distance acuity (r = 0.78), followed by contrast sensitivity (r = 0.75), and near acuity (r = 0.67). The agreement between the standard and tablet-based methods did not appear to be dependent on the level of vision.Conclusions: This study demonstrates the agreement of tablet-based and gold-standard tests of visual function in older adults. These findings have important implications for future population vision health surveillance and research.

Evaluating Goldmann Applanation Tonometry Intraocular Pressure Measurement Agreement Between Ophthalmic Technicians and Physicians

PURPOSE

To examine IOP measurement disagreement between technicians and physicians and the impact of an educational intervention on the short and long-term disagreement in IOP measurement using Goldmann applanation tonometry.

DESIGN

Prospective study designed to enhance measurement reliability.

SETTING

A glaucoma clinic at a university hospital. StudyPopulation: 6 technicians and 2 physicians.

INTERVENTION

An educational intervention was implemented for the technicians to improve IOP measurement agreement with physicians. MainOutcomeMeasures: Frequency of IOP measurement disagreement between physicians and technicians, defined as a difference in IOP of >2 or >3 mm Hg and assessed at baseline and immediately and 6 months postintervention.

RESULTS

IOP was evaluated for a total of 529 eyes (physician measured mean IOP = 16.4 mm Hg [SD = 5.9]), 30 per technician-physician pair for each data collection period: baseline, immediately postintervention and 6 months postintervention. At baseline, physicians disagreed 17% and 7% of the time when measuring IOP using >2 and >3 mm Hg to define disagreement, respectively, whereas the average disagreement between technicians and physicians was 25% and 13%. Disagreement was greater at IOPs greater than 20 mm Hg. No significant changes were noted in the frequency of disagreement between technicians and physicians immediately or 6 months postintervention.

CONCLUSIONS

Two physicians measuring the same patient in the same room disagreed by >2 mm Hg in 17% of patients' eyes, and this amount of disagreement was even higher when comparing physicians to certified technicians. An educational intervention did not improve agreement in IOP measurements between technicians and physicians. This highlights an important limitation of Goldmann tonometry.

Caring for Older Adults With Vision Impairment and Dementia

BACKGROUND AND OBJECTIVES

Dementia and vision impairment (VI) are common among older adults but little is known about caregiving in this context.

RESEARCH DESIGN AND METHODS

We used data from the 2011 National Health and Aging Trends Study, a nationally representative survey of Medicare beneficiaries, linked to their family/unpaid helpers from the National Study of Caregiving. Vision impairment was defined as self-reported blindness or difficulty with distance/near vision. Probable dementia was based on survey report, interviews, and cognitive tests. Our outcomes included hours of care provided, and number of valued activities (scored 0-4) affected by caregiving, per month.

RESULTS

Among 1,776 caregivers, 898 (55.1%, weighted) assisted older adults without dementia or VI, 450 (21.9%) with dementia only, 224 (13.0%) with VI only, and 204 (10.0%) with dementia and VI. In fully adjusted negative binomial regression analyses, caregivers of individuals with dementia and VI spent 1.7 times as many hours (95% confidence interval [CI] = 1.4-2.2) providing care than caregivers of those without either impairment; however, caregivers of individuals with dementia only (95% CI = 1.1-1.6) and VI only (95% CI = 1.1-1.6) spent 1.3 times more hours. Additionally, caregivers of individuals with dementia and VI had 3.2 times as many valued activities affected (95% CI = 2.2-4.6), while caregivers of dementia only and VI only reported 1.9 times (95% CI = 1.4-2.6) and 1.3 times (95% CI = 0.9-1.8) more activities affected, respectively.

DISCUSSION AND IMPLICATIONS

Our results suggest that caring for older adults with VI involves similar time demands as caring for older adults with dementia, but that participation impacts are greater when caring for older adults with both dementia and VI.

Is Sensory Loss an Understudied Risk Factor for Frailty? A Systematic Review and Meta-analysis

Background

Age-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.

Methods

In 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.

Results

We 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.

Conclusions

Our 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.

The Association between Frailty and Uncorrected Refractive Error in Older Adults

Purpose: Uncorrected refractive error (URE) is the leading cause of impaired vision in older adults and has been associated with adverse health outcomes. Here, we investigate the association between URE and frailty in older adults.Methods: This is a cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) participants ≥60 years (1999-2006 cycles). URE was defined as visual acuity worse than 6/12 that can be improved with correction, and prefrailty and frailty were defined as meeting 1-2 and ≥3 of 4 components of a modified physical frailty phenotype. The 5-item phenotype (including slowness) was analyzed in a subset of participants with available data. Propensity score adjustment was used to address the imbalance of potential confounders (including age) between URE groups.Results: In this sample (n = 5,265), 6% of participants had URE (n = 373). In fully adjusted propensity score-based models, individuals with URE were more likely to be prefrail (OR = 1.4; 95% CI: 1.0-2.0) and frail (OR = 3.2; 95% CI: 1.3-7.4) than those without URE using the 4-item phenotype. For the 2,486 participants with 5-item phenotype data, individuals with URE were more likely to be frail (OR = 3.0; 95% CI: 1.2-7.5); however, the association with prefrailty was not statistically significant (OR = 1.8; 95% CI: 0.9-3.6).Conclusion: In this population-based sample, older adults with URE were more likely to be frail than those without URE, even after rigorous control for confounders, including age.
