Vision Impairment and the Population Attributable Fraction of Dementia in Older Adults.

Importance: Vision impairment is a potentially modifiable risk factor for dementia. Although few prior studies have estimated the contribution of vision impairments to dementia, none have reported on multiple objectively measured vision impairments (eg, distance and near visual acuity and contrast sensitivity) in a nationally representative sample of older adults. Objective: To quantify population attributable fractions of dementia from objective vision impairments in older adults, stratified by age, self-reported sex, self-reported race and ethnicity, and educational attainment. Design, Setting, and Participants: This was a population-based cross-sectional analysis in the National Health and Aging Trends Study, which gathers nationally representative information on Medicare beneficiaries aged 65 years and older in the US. A total of 2767 community-dwelling adults eligible for vision and cognitive testing in 2021 were included. Data were analyzed from April to August 2023. Exposures: Near and distance visual acuity impairments were each defined as >0.30 logMAR. Contrast sensitivity impairment was defined as <1.55 logCS. At least 1 vision impairment was defined as impairment to either near acuity, distance acuity, or contrast sensitivity. Main Outcomes and Measures: Adjusted population attributable fractions of prevalent dementia, defined using a standardized algorithmic diagnosis (≥1.5 SDs below mean on 1 or more cognitive domains, self- or proxy-reported dementia diagnosis, or the Ascertain Dementia-8 Dementia Screening Interview Score of probable dementia). Results: The survey-weighted prevalence of vision impairment among participants aged 71 and older (1575 [54.7%] female and 1192 [45.3%] male; 570 [8.0%] non-Hispanic Black, 132 [81.7%] Hispanic, 2004 [81.7%] non-Hispanic White, and 61 [3.3%] non-Hispanic other) was 32.2% (95% CI, 29.7-34.6). The population attributable fraction of prevalent dementia from at least 1 vision impairment was 19.0% (95% CI, 8.2-29.7). Contrast sensitivity impairment yielded the strongest attributable fraction among all impairments (15.0%; 95% CI, 6.6-23.6), followed by near acuity (9.7%; 95% CI, 2.6-17.0) and distance acuity (4.9%; 95% CI, 0.1-9.9). Population attributable fractions from at least 1 impairment were highest among participants aged 71 to 79 years (24.3%; 95% CI, 6.6-41.8), female (26.8%; 95% CI, 12.2-39.9), and non-Hispanic White (22.3%; 95% CI, 9.6-34.5) subpopulations, with estimates consistent across educational strata. Conclusions and Relevance: The population attributable fraction of dementia from vision impairments ranged from 4.9%-19.0%. While not proving a cause-and-effect relationship, these findings support inclusion of multiple objective measures of vision impairments, including contrast sensitivity and visual acuity, to capture the total potential impact of addressing vision impairment on dementia.

Experiences of researchers with disabilities at academic institutions in the United States.

INTRODUCTION: People with disabilities are underrepresented in higher education, facing systematic obstacles such as inaccessible communication and physical environments and difficulties obtaining accommodations. This study aims to shed light on barriers to accessibility and disability inclusion in research institutions through confidential qualitative interviews with researchers with disabilities. METHODS: We recruited participants via virtual flyers. Eligibility criteria included working in the United States (U.S.) as researchers that had applied for grant funding (last five years), and self-identifying as having a disability. We offered participants (total n = 35) the option of either semi-structured one-on-one live or written interviews based on their preference. Two study team members analyzed written and live responses using thematic analysis to identify themes. RESULTS: Themes included identity/visibility, career trajectories, accessibility, accommodations, bias, representation, and inclusion. Some participants reported not disclosing their disabilities at work or during hiring processes due to fear of negative perceptions from peers or potential employers. Experiences around stigma and bias were noted both in professional relationships and when interacting with disability service offices, underscoring difficulties and delays in processes to secure accommodations. Respondents highlighted the lack of disability inclusion and low representation of people with disabilities in academia and elevated the importance of self-advocacy and of role models and mentors in shaping career pathways for future researchers with disabilities. CONCLUSION: Researchers with disabilities encounter systematic barriers at academic institutions, and lack of acknowledgement and research on these experiences has held back institutional and policy changes. To reduce disparities for researchers with disabilities, academic leadership must allocate resources to address ableism, create more inclusive environments, and raise standards beyond compliance with the Americans with Disabilities Act.

Longitudinal Changes in Visual Acuity and Contrast Sensitivity and Incident Dementia.

PURPOSE: To evaluate the impact of baseline and change in vision on the risk of developing dementia. DESIGN: Retrospective cohort study. METHODS: This longitudinal analysis utilized data from the 2021 and 2022 National Health and Aging Trends Study. Binocular presenting vision was assessed, including distance (DVA) and near (NVA) visual acuity, and contrast sensitivity (CS). Dementia status was defined based on: (1) medical diagnosis of dementia, (2) dementia score, or (3) poor cognitive test performance. RESULTS: Of the 2,159 adults included in this study, weighted mean (SD) age was 77.9 years (5.2), with the majority being female (weighted: 54%), and White (88%). The baseline median (interquartile range [IQR]) DVA was 0.08 (0-0.20) logMAR, NVA was 0.17 (0.09-0.26) logMAR, and CS was 1.80 (1.65-1.85) logCS. Over the 1-year follow up period, 192 (6.6%) adults developed dementia. In time-to-event analyses, baseline DVA (HR: 1.08 [95% CI: 1.02-1.14], per 0.1 logMAR), NVA (HR: 1.07 [95% CI: 1.01-1.13], per 0.1 logMAR), and CS (HR: 1.09 [95% CI: 1.03-1.15], per 0.1 logCS) were associated with greater likelihood of incident dementia. Further, change in CS (HR: 1.14 [95% CI: 1.04-1.25], per 0.1 logCS worse/year), but not VA, was associated with greater likelihood of incident dementia. CONCLUSIONS: Worse baseline VA and CS are associated with greater likelihood of incident dementia. Further, worsening CS over time, but not VA, was associated with higher likelihood of incident dementia. Future work is needed to study interventions targeted at improving vision deficits and examine their impact on decreasing dementia risk.

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.

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 and hearing difficulty and effects of cognitive training in older adults.

BACKGROUND: Cognitive training is delivered visually and aurally. It is unknown whether self-reported sensory difficulty modifies the effects of cognitive training on cognition. METHODS: Participants (N = 2788) in the Advanced Cognitive Training for Independent and Vital Elderly Study were randomized to training in memory, reasoning, speed of processing, or control. Differences in the 10-year effect of cognitive training on cognition by self-reported vision and hearing difficulty were assessed using linear mixed effect models. RESULTS: Benefit (intervention vs. control) of reasoning training was smaller among participants with versus without vision difficulty (difficulty: -0.25, 95% confidence interval: [-0.88, 0.39], no difficulty: 0.58 [0.28, 0.89]). Benefit of memory training was greater for participants with versus without hearing difficulty (difficulty: 0.17 [-0.37, 0.72], no difficulty: -0.20 [-0.65, 0.24]). DISCUSSION: Older adults with sensory loss have increased risk for cognitive decline; benefits of cognitive training may be greater for these individuals. Sensory loss should be considered in training design. Highlights: Memory training was more beneficial for participants with hearing loss.Participants with vision difficulties did not benefit as much from reasoning training.Low accessibility in design and learned compensation strategies may contribute.Consideration of sensory impairment in study design is needed.Inclusion of older adults with sensory impairment in cognitive training is needed.

Hearing and vision impairment and social isolation over 8 years in community-dwelling older adults.

BACKGROUND: Little is known about the long-term impact of hearing and vision impairment on social isolation. This study quantifies the association between hearing, vision, and concurrent hearing and vision impairment (dual sensory impairment) and social isolation over 8 years among older adults. METHODS: Data were from the National Health and Aging Trends Study (NHATS), a cohort study (2011 - 2019) of U.S. Medicare beneficiaries aged 65 years and older. Social isolation was measured by a binary indicator incorporating four domains: living arrangement, core discussion network size, religious attendance, and social participation. Hearing, vision, and dual sensory impairments were measured by self-report and modeled categorically (no impairment [ref.], hearing impairment only, vision impairment only, dual sensory impairment). Associations between sensory impairments and odds of social isolation over 8 years were assessed using multivariate generalized logistic mixed models and adjusted for demographic and health characteristics. RESULTS: Among 5,552 participants, 18.9% self-reported hearing impairment, 4.8% self-reported vision impairment, and 2.3% self-reported dual sensory impairment. Over 8 years, hearing impairment only was associated with 28% greater odds of social isolation. Participants with hearing impairment only were more likely to live alone and have limited social participation. CONCLUSION: Greater clinical awareness of hearing impairment as a risk factor for social isolation can increase opportunities to identify and aid older adults who may benefit from resources and interventions to increase social connection and mitigate social isolation.

Sensory and motor deficits as contributors to early cognitive impairment.

INTRODUCTION: Age-related sensory and motor impairment are associated with risk of dementia. No study has examined the joint associations of multiple sensory and motor measures on prevalence of early cognitive impairment (ECI). METHODS: Six hundred fifty participants in the Baltimore Longitudinal Study of Aging completed sensory and motor function tests. The association between sensory and motor function and ECI was examined using structural equation modeling with three latent factors corresponding to multisensory, fine motor, and gross motor function. RESULTS: The multisensory, fine, and gross motor factors were all correlated (r = 0.74 to 0.81). The odds of ECI were lower for each additional unit improvement in the multisensory (32%), fine motor (30%), and gross motor factors (12%). DISCUSSION: The relationship between sensory and motor impairment and emerging cognitive impairment may guide future intervention studies aimed at preventing and/or treating ECI. HIGHLIGHTS: Sensorimotor function and early cognitive impairment (ECI) prevalence were assessed via structural equation modeling. The degree of fine and gross motor function is associated with indicators of ECI. The degree of multisensory impairment is also associated with indicators of ECI.

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.

TRansit ACessibility Tool (TRACT): Developing a novel scoring system for public transportation system accessibility.

Introduction: Although federal laws require equal access to public transportation for people with disabilities, access barriers persist. Lack of sharing accessibility information on public transportation websites restricts people with disabilities from making transportation plans and effectively using public transportation systems. This project aims to document information provided about public transportation systems accessibility and share this information using an open data platform. Methods: We reviewed the top twenty-six public transportation systems in the United States based on federal funding in fiscal year 2020. Information about accessibility was abstracted from each public transportation system website by two independent reviewers from February-March 2022. Informed by universal design principles, public transportation systems were scored across six dimensions: facility accessibility (0-22 points), vehicle accessibility (0-11 points), inclusive policies (0-12 points), rider accommodations (0-9 points), paratransit services (0-6 points), and website accessibility (0-2 points). Total scores were calculated as the sum of each dimension (0-62 points). Data and findings were publicly disseminated (https://disabilityhealth.jhu.edu/transitdashboard/). Results: The average overall accessibility information score was 31.9 (SD=6.2) out of 62 possible points. Mean scores were 8.4 (SD=2.9) for facility accessibility, 4.5 (SD=2.1) for vehicle accessibility, 7.8 (SD=1.6) for inclusive policies, 4.9 (SD=1.6) for rider accommodations, 4.5 (SD=2.0) for paratransit services, and 1.8 (SD=0.4) for website accessibility. Eleven public transportation systems (42%) received the maximum score for paratransit services and 20 (77%) received the maximum score for website accessibility. No public transportation system received the maximum score for any of the other dimensions. Conclusions: Using a novel scoring system, we found significant variation in the accessibility information presented on public transportation system websites. Websites are a primary mode where users obtain objective information about public transportation systems and are therefore important platforms for communication. Absence of accessibility information creates barriers for the disability community and restricts equal access to public transportation.

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.

Counting disability in the National Health Interview Survey and its consequence: Comparing the American Community Survey to the Washington Group disability measures.

BACKGROUND: The objective of the National Health Interview Survey (NHIS) is to provide data that can be used to monitor the health of the US population. OBJECTIVE: In this study, we evaluate whether the disability questions currently used in the NHIS - the Washington Group questions - threaten the ability of this survey to fulfil its stated objective for disabled people. METHODS: Data were from the 2011-2012 NHIS with linkage to mortality status through 2019. We examined whether people who reported a disability in the American Community Survey disability questions had their disability counted in the Washington Group questions. We then examined the consequence of use of the Washington Group as opposed to the American Community Survey questions, on estimates of disability prevalence and comparative mortality risk. RESULTS: We find that when compared to their predecessor, the American Community Survey disability questions, the Washington Group questions accounted for less than half of disabled people, primarily counting disabled people with more than one disability status, but not counting many disabled people with only one disability status. As a result of this undercount, disability prevalence rates based on the Washington Group questions underestimate the size of the disabled population in the US, and overestimate the comparatively higher mortality risk associated with disability status. CONCLUSIONS: These results underscore the need to re-evaluate the disability questions used in the NHIS, and invest in the development of improved and expanded disability questionnaires for use in national surveys.

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.

Telehealth and digital health innovations: A mixed landscape of access.

In the wake of emergent natural and anthropogenic disasters, telehealth presents opportunities to improve access to healthcare when physical access is not possible. Yet, since the beginning of the COVID pandemic, lessons learned reveal that various populations in the United States do not or cannot adopt telehealth due to inequitable access. We explored the Digital Determinants of Health (DDoHs) for telehealth, characterizing the role of accessibility, broadband connectivity and electrical grids, and patient intersectionality. In addition to its role as an existing Social Determinant of Health, Policies and Laws directly and indirectly affect these DDoHs, making access more complex for marginalized populations. Digital systems lack the flexibility, accessibility, and usability to inclusively provide the essential services patients need in telehealth. We propose the following recommendations: (1) design technology and systems using accessibility and value sensitive design principles; (2) support a range of technologies and settings; (3) support multiple and diverse users; and (4) support clear paths for repair when technical systems fail to meet users' needs. Addressing these requires change not only from providers but also from the institutions providing these systems.

Revising NIH's Mission Statement to Remove Ableist Language.

This Viewpoint emphasizes the importance of policy statements using "person-first" language to mitigate discrimination against people with disabilities and to boost modern views in the medical and research communities.

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.

Food insecurity gaps in the Supplemental Nutrition Assistance Program based on disability status.

BACKGROUND: Households including someone with disabilities experience disproportionately high food insecurity rates and likely face disproportionate barriers accessing Supplemental Nutrition Assistance Program (SNAP) benefits. OBJECTIVE: This article aims to examine the role of SNAP with regard to food insecurity disparities based on disability status. METHODS: Modified Poisson regression models examined food insecurity risk based on disability status (household includes no one with disabilities vs. those with work-limiting disabilities or non-work-limiting disabilities) among 2018 Survey of Income and Program Participation households eligible for SNAP (income ≤130% of the poverty threshold). Weighted estimates were used to account for the study design and non-response. RESULTS: Households including someone with work-limiting disabilities were more than twice as likely to be food insecure than households including no one with disabilities (PR = 2.16, 95% CI: 1.90, 2.45); households including someone with non-work-limiting disabilities were 65% more likely (PR = 1.65, 95% CI: 1.39, 1.95). However, disparities were more pronounced among households not participating in SNAP (PR = 2.67, 95% CI: 2.22, 3.23 for work-limiting disabilities and PR = 1.86, 95% CI: 1.44, 2.40 for non-work-limiting disabilities) than SNAP-participating households (PR = 1.71, 95% CI: 1.45, 2.03 and PR = 1.46, 95% CI: 1.17, 1.82, respectively). Approximately 4.2 million low-income U.S. households including someone with disabilities are food insecure. Of these, 1.4 million were not participating in SNAP and another 2.8 million households were food insecure despite participating in SNAP. CONCLUSIONS: Access to SNAP benefits is not proportionate to the scale of food insecurity among households that include people with disabilities. Action is needed to strengthen food assistance for those with disabilities.

Prevalence of Disability and Use of Accommodation Among US Allopathic Medical School Students Before and During the COVID-19 Pandemic.

This survey study assesses self-disclosures of disability, disability types, and accommodation needs reported by US allopathic medical schools in 2021 vs 2015 and 2019.
