RESUMEN
SIGNIFICANCE: Future work should develop and evaluate interventional strategies to help overcome visual and health-related barriers to travel in visually impaired seniors and mitigate adverse impacts of loneliness for those who do not leave town. PURPOSE: Life space refers to the area in which a person travels within a given time period. We explored whether demographics, vision, and/or health characteristics were related to restrictions in self-reported life space for visually impaired seniors. METHODS: Visually impaired (n = 114) clinical trial participants aged ≥55 years learned visual assistive iPhone apps and completed the following baseline questionnaires: Life Space, 36-Item Short-Form Health Survey, University of California, Los Angeles Loneliness Scale, and New-General Self-efficacy Scale. Multiple logistic regressions evaluated associations between life space and patient factors after accounting for their distance to the next county or state. RESULTS: During 2021 to 2023, 17%, 43%, and 70% of participants had not left their town, county, or state, respectively, in the past 3 months, or planned to in the next 3 months. Those with reduced distance best-corrected visual acuity had greater odds of not leaving the county in these time frames (odds ratio [OR] = 3.5; p=0.04). Minority race was associated with greater odds of not leaving town or the county in the past 2 weeks or future 3 months (OR = 4.3 to 6.4; p=0.009 to 0.049). Increased self-efficacy was associated with reduced odds of not leaving the state in the past 3 months, next 3 months, or past and/or future 3 months (OR = 0.54 to 0.55; p=0.02 to 0.03). Better physical function was associated with reduced odds of not leaving the state in the past 2 weeks or 3 months (OR = 0.96 to 0.98; p=0.01 to 0.04). Increased loneliness was related to greater odds of not leaving town in the past and/or future 3 months (OR = 1.8 to 2.0; p=0.007 to 0.009). CONCLUSIONS: Minority race, reduced vision, self-efficacy, and physical health were related to life space restrictions in this cohort of visually impaired seniors, whereas loneliness was greater among those who were not leaving town.

SIGNIFICANCE: Autonomous vehicles (AVs) have the promise to be an alternative transportation solution for those with vision loss. However, the impact of vision loss on the perceptions and concerns of AVs is unknown. This study therefore examined whether AVs are perceived differently by blind, visually impaired (VI), and normally sighted people. PURPOSE: This study compared the perceptions of AVs among the blind, VI, and normally sighted. METHODS: Participants' opinions on four perception measures (general opinion, trust, impact on quality of life, and intention to use AVs) and nine concerns regarding AVs were measured. The survey was administered to 51 normally sighted, 68 VI, and 65 blind participants. Analyses of covariance assessed whether the four perception measures and nine concerns varied by vision status (normal vision, VI, blind) and driving status (driver, nondriver). Univariate correlations and multiple regression analyses identified associations and predictors of AV perceptions and concerns from demographic, mood, cognition, travel behavior, and vision measures, which included visual acuity, contrast sensitivity, and visual field. RESULTS: The blind (p<0.001), VI (p<0.001), and nondrivers (p<0.001) showed a greater intention to use AVs compared with those with normal vision and drivers. Similar findings were found for the other perception measures. As visual acuity, contrast sensitivity, and visual field extent declined, positivity toward AVs increased (p<0.001). Visual field extent best predicted general opinion and trust in AVs, whereas driving measures were the best predictors of impact on quality of life and intention to use AVs. Concerns about AVs showed no differences based on vision (p=0.94) or driving (p=0.63) status. CONCLUSIONS: Individuals with vision loss expressed more acceptance of AVs despite their concerns. How positive someone is toward AVs appears to be dependent on their visual field extent and driving status.

Purpose: Bioptic telescopic spectacles can allow individuals with central vision impairment to obtain or maintain driving privileges. The purpose of this study was to (1) compare hazard perception ability among bioptic drivers and traditionally licensed controls, (2) assess the impact of bioptic telescopic spectacles on hazard perception in drivers with vision impairment, and (3) analyze the relationships among vision and hazard detection in bioptic drivers. Methods: Visual acuity, contrast sensitivity, and visual field were measured for each participant. All drivers completed the Driving Habits Questionnaire. Hazard perception testing was conducted using commercially available first-person video driving clips. Subjects signaled when they could first identify a traffic hazard requiring a change of speed or direction. Bioptic drivers were tested with and without their bioptic telescopes in alternating blocks. Hazard detection times for each clip were converted to z-scores, converted back to seconds using the average response time across all videos, and then compared among conditions. Results: Twenty-one bioptic drivers and 21 normally sighted controls participated in the study. The hazard response time of bioptic drivers was improved when able to use the telescope (5.4 ± 1.4 seconds vs 6.3 ± 1.8 seconds without telescope); however, it remained significantly longer than for controls (4.0 ± 1.4 seconds). Poorer visual acuity, contrast sensitivity, and superior visual field sensitivity loss were related to longer hazard response times. Conclusions: Drivers with central vision loss had improved hazard response times with the use of bioptic telescopic spectacles, although their responses were still slower than normally sighted control drivers. Translational Relevance: The use of a bioptic telescope by licensed, visually impaired drivers improves their hazard detection speed on a video-based task, lending support to their use on the road.

BACKGROUND: Visual impairment has been strongly associated with the incidence of dementia. Appropriate cognitive screening for the elderly with visual impairment is crucial for early identification of dementia and its management. Due to challenges in processing visually presented stimuli among participants, the cut-off score of the Hong Kong version of the Montreal Cognitive Assessment for the Visually Impaired (HKMoCA-VI), also known as MoCA-BLIND or MoCA-22, was unknown. Besides, the cognitive status of elderly with visual impairment residing in care homes is rarely investigated. The current study aimed to 1) establish the cut-off score for HKMoCA-VI and 2) examine the general cognitive functioning of elderly with visual impairment living in residential homes in Hong Kong in terms of MoCA-VI percentile scores. METHOD: HKMoCA-VI and the Cantonese version of the Mini-Mental State Examination (CMMSE) were administered to 123 visually impaired elderly residents in care homes in Hong Kong. Percentile scores of HKMoCA-VI by age and education level were determined, and the concurrent validity, sensitivity, and specificity of HKMoCA-VI were assessed. RESULTS: A cut-off score 12 was suggested for HKMoCA-VI, which yielded a sensitivity and specificity of 89.29% and 83.58%, respectively. Moreover, it strongly correlated with CMMSE, indicating satisfactory concurrent validity. CONCLUSIONS: HKMoCA-VI is suggested to be a viable cognitive screening tool for elderly individuals with visual impairment in residential homes. Further modifications to enhance the sensitivity and specificity of the measure are proposed.

Visual stimuli play key roles in influencing men sexual behavior. However, few studies have explored the sexual behavior of blind men. To provide more information about blind men for the study of andrology by surveying the characteristics of their current sexual behavior. A questionnaire-based cross-sectional study design was performed. The questionnaire contained questions regarding demographic characteristics of participants, access to sexual knowledge, perception of the sexual partners' beauty, and sexual arousal. Blind men were interviewed face-to-face by the trained investigator. Complete questionnaires were collected from 54 participants, with an average age of 40.57â ±â 9.80 years old. Eye diseases were the most frequent cause of blindness. In terms of sexual orientation, all participants were heterosexual. Notably, 90.7% of the participants reported to have had a sexual experience. Among those who had engaged in sexual behavior, 93.6% experienced sexual pleasure and 69.4% had a normal erectile function. Overall, 16.7% of the participants received sex education. The participants obtained sexual knowledge mainly through sounds from mobile phones, peer-to-peer communication, sounds of television and radio. Voice was the most frequent perception of the sexual partners' beauty, followed by figure, skin, and body fragrance. In terms of stimuli of sexual arousal, tactile sensation and auditory sensation in that order were the most frequent stimuli of sexual arousal. Stimuli of sexual arousal in blind men are mainly mediated by sound and touch. Blind men understand their sexual partners' beauty through auditory, tactile, and olfactory sensations. Blind men in Ganzhou lack formal and systematic sex education.

PURPOSE: This study examined how ableism influences blind and visually impaired women's experiences accessing and engaging in exercise, physical activity, and sport. METHODS: Ten women between the ages of 27 and 45 years completed a one-on-one audio-recorded virtual interview where they reflected on the meaningfulness of their exercise, physical activity, and/or sport experiences, as well as described any experiences related to direct, indirect, systemic, or internalized ableism within or when attempting to access those physical activity experiences. The interview transcripts were analyzed using reflexive thematic analysis. FINDINGS: The analysis resulted in the construction of 2 themes that depicted the participants' experiences: (1) "It's exhausting": navigating inaccessibility and (2) "You feel like a fish out of water": internalized ableism. DISCUSSION: The themes highlight the participants' experiences which were largely focused on being forced to navigate inaccessible environments which resulted in exhaustion and expressions of internalized ableism. These findings provide insight into what makes and does not make a physical activity space accessible and welcoming for blind and visually impaired adults.

In this paper, we analyze the subjective inclusion experiences of visually impaired (VI) adult tennis players from an ableism-critical perspective. The primary focus of this research is the inclusive potential of blind tennis from the perspective of VI individuals. Episodic interviews were conducted to capture subjective perspectives. A qualitative text analysis revealed that the interviewees were confronted with multiple ability assumptions by sighted people in their everyday lives. Deficit notions on the performance of VI people included sports, work, and general activities. Participation in blind tennis helped the interviewees build a "competent identity" and acquire various skills useful for their everyday lives as participation in blind tennis was a pathway for competence in sports. Further research is needed to identify exclusion experiences from the perspective of disabled people to recognize the potential of different sports in reducing barriers to participation.

BACKGROUND: It is well established that meeting physical activity (PA) guidelines has a range of physical and mental health benefits. For people who are blind and vision impaired (BVI) there may be additional benefits in terms of social inclusion and the prevention of sight deterioration. OBJECTIVE: This study aimed to quantify PA levels, barriers to and motivators for PA in adults who are BVI. METHODS: PA levels, perceived barriers to, and motivators for PA were measured via questionnaire of 310 self-identifying BVI adults (n = 310 mean age = 29.77 ± 11.37, 55.8% male). RESULTS: PA levels were low, with 21.7% meeting PA guidelines. Median PA levels were not statistically significantly different between different age groups. There was no significant difference between genders, though mean days of PA for males was 0.382 days lower than for females. There was a significant difference between PA levels between the "no vision" (B1) and "useful vision" (B3) groups (p = 0.027), and the "no vision" (B1) and the "low vision" (B2) groups (p = 0.003). Transport (54.8%) and lack of access to enjoyable activities (47.0%) were the most commonly cited barriers, while "to relax" (36.4%) and "to have fun" (35.6%) were most commonly cited as very important motivators. CONCLUSIONS: This study provides a valuable insight into the low levels of PA that persist amongst adults with BVI. Future research should seek to gain a deeper understanding of the PA barriers, motivators and facilitators in this cohort.

PURPOSE: The main objective of this study is to assess the test-retest and inter-administration mode reliability of the Impact of Vision Impairment profile (IVI), a common patient-reported outcome measure (PROM) for people with chronic eye diseases. METHODS: The IVI was administered to adult patients with stable, chronic eye diseases two to four times per participant (average intervals between administrations 12 to 20 days; maximum two phone interviews, paper administration, electronic administration) by two trained interviewers. Rasch models were fit to the data. Intra-class correlation coefficients (ICCs), mean differences and Cronbach's alpha between test-retest administrations (two phone interviews) and inter-mode comparisons were calculated. RESULTS: Two hundred-sixteen patients (mean age 67 ± 12 years, 40% male) were included in the study. The IVI met all psychometric requirements of the Rasch model, and the division into the domains of functional items (IVI_F) and emotional items (IVI_E) corresponded to the German validation study. ICCs (all for IVI_F and IVI_E, respectively) for the retest administrations were 0.938 and 0.912, and 0.853 and 0.893 for inter-mode comparisons phone/paper, 0.939 and 0.930 for phone/electronic, and 0.937 and 0.920 for paper/electronic (all p < 0.01). Mean differences (all for IVI_F and IVI_E, respectively) for the retest administrations were 2.8% and 0.7% and ranged from 2.0% to 6.2% and from 0.4 % to 4.9% between administration modes. Cronbach's alpha ranged from 0.886 to 0.944 for retest and inter-mode comparisons. CONCLUSION: Due to the high test-retest reliability and the almost equally high comparability of different modes of administration of the IVI, the study endorses its use as a robust PROM to capture vision-related quality of life. Our results further support the use of the IVI as an endpoint in clinical trials and may simplify implementing it in both clinical trials or real-world evidence generation by offering multiple administration modes with high reliability.

BACKGROUND: To study the mental health status of patients with visual impairment in a tertiary institution in Southwestern Nigeria. OBJECTIVES: To determine the mental health status of individuals with loss of vision in Ogbomoso and associated factors. METHODOLOGY: A descriptive cross-sectional study. Questionnaires were administered to obtain information on the socio-demographic characteristics and mental health status. Test for association was done. A total score greater than or equal to 4 out of the 28 items of the General Health Questionnaire was considered a case of mental ill-health. RESULTS: 250 subjects were studied, out of which 126 (50%) were found to have mental ill-health. Statistically significant association was found between age, level of education, occupation, duration of loss of vision, and pattern of loss of vision (p-values < 0.001, 0.020, 0.001, and 0.001 respectively) in bivariate analysis, however, age and pattern of vision loss were not significantly associated with loss of vision in multivariate analysis. Those who lost their vision less than two years from the time of the study had a higher risk of mental health morbidity. Those with sudden vision loss were 3.48 times more likely to have mental health morbidity in bivariate analysis, compared with those with progressive visual loss. CONCLUSION: The prevalence of mental ill-health among people with vision loss is high. Associated factors included level of education, occupation and duration of loss of vision. Predictors of good mental health included younger age group, higher level of education, being employed, longer duration of loss of vision and progressive pattern of vision loss.
CONTEXTE: Étudier l'état de santé mentale des patients atteints de déficience visuelle dans un établissement tertiaire du sud-ouest du Nigeria. OBJECTIFS: Déterminer l'état de santé mentale des personnes souffrant d'une perte de vision à Ogbomoso et les facteurs associés. MÉTHODOLOGIE: Étude descriptive transversale. Des questionnaires ont été administrés pour obtenir des informations sur les caractéristiques sociodémographiques et l'état de santé mentale. Un test d'association a été effectué. Un score total supérieur ou égal à 4 sur les 28 items du General Health Questionnaire a été considéré comme un cas de mauvaise santé mentale. RÉSULTATS: 250 sujets ont été étudiés, dont 126 (50 %) présentaient une mauvaise santé mentale. Une association statistiquement significative a été trouvée entre l'âge, le niveau d'éducation, la profession, la durée de la perte de vision et le type de perte de vision (valeurs p < 0,001, 0,020, 0,001 et 0,001 respectivement) dans l'analyse bivariée, cependant, l'âge et le type de perte de vision n'étaient pas significativement associés à la perte de vision dans l'analyse multivariée. Les personnes ayant perdu la vue moins de deux ans après le début de l'étude présentaient un risque plus élevé de morbidité mentale. Les personnes ayant subi une perte soudaine de la vue étaient 3,48 fois plus susceptibles de souffrir de morbidité mentale dans l'analyse bivariée, par rapport à celles ayant subi une perte progressive de la vue. CONCLUSION: La prévalence de la mauvaise santé mentale chez les personnes souffrant d'une perte de vision est élevée. Les facteurs associés sont le niveau d'éducation, la profession et la durée de la perte de vision. Les facteurs prédictifs d'une bonne santé mentale sont le groupe d'âge le plus jeune, le niveau d'éducation le plus élevé, le fait d'avoir un emploi, la durée la plus longue de la perte de vision et le modèle progressif de la perte de vision.

Older adults are likely to develop adverse drug events owing to age-related changes in pharmacokinetics and polypharmacy. In terms of pharmacokinetics, the drug should be prescribed at a reduced dose, which should be reconsidered and reduced during long-term use. For polypharmacy, "List of drugs to be prescribed with special caution" should be referred and deprescription should be practiced in consideration of the priority of treatment. Because older adults often show reduced ability to manage their medication due to cognitive dysfunction, low visual acuity, and hearing loss, measures should be taken to maintain their adherence.

OBJECTIVE: Pain evaluation scales often rely on the sense of sight. There is so far no pain assessment scale designed specifically for persons with visual impairment. DESIGN: This study aims to validate a tactile pain evaluation scale, Visiodol (Copyright Prof Pickering), in blind or visually impaired persons, by correlation with a numeric pain scale. SETTING: The study took place at University Hospital Clermont-Ferrand, France. METHODS: Pain intensity for a range of thermal stimuli (Pathway Medoc) was evaluated with Visiodol and a numeric pain scale. Secondary outcomes, including pain thresholds, catastrophizing, emotion, and quality of life, were compared in persons who were blind or visually impaired and in sighted persons. Lin's concordance correlation coefficient was estimated. Weighted Cohen's κ accounted for degrees of disagreement between scales with 95% confidence intervals (95% CI). SUBJECTS: Sixteen healthy sighted and 21 healthy nonsighted volunteers (n = 13 congenital, n = 8 acquired) were included. RESULTS: Lin's correlation coefficient for repeated data was 0.967 (95% CI, 0.956-0.978; P < 0.001) for visually impaired participants, with a good agreement at each temperature plateau. A weighted Cohen's κ of 0.90 (95% CI, 0.84-0.92) and 92.9% percentage of agreement for visually impaired participants were satisfactory. Pain perception, psychological components, and quality of life were more impaired in persons who were blind or visually impaired than in sighted persons. CONCLUSIONS: This study validates Visiodol, a tactile scale for persons who are blind or visually impaired, and addresses health care inequalities in the context of pain evaluation. Visiodol will now be tested in a larger population of patients to give the millions of persons worldwide who are blind or visually impaired an option for pain intensity evaluation in clinical situations.

Emotion regulation develops from the earliest years of a child's life and mostly through visual information. Considering the importance of emotion regulation in daily life situations, it is important to study the effect of visual experience on the development of this ability. This study is the first to examine the effect of visual experience and age in emotion regulation by comparing groups of children with different visual status and age. For this purpose, after testing the reliability and consistency of the French version of Emotion Regulation Checklist (ERC-vf) with 245 parents of blind, visually impaired and sighted children aged 3-5, 6-8 or 9-12 years, we conducted analyses on the effect of visual status and age on emotion regulation composite scores. The first result confirmed that the ERC-vf can be reliably used on populations of blind and visually impaired children. The second result revealed an effect of visual status on ER composite scores of emotion regulation: Blind children and visually impaired children each had significantly lower composite scores than sighted children. Moreover, the effect of age and the interaction between age and visual status were not significant on ER composite scores. The ER subscale results suggest, however, that age may have a variable effect for blind and visually impaired children as blind children's scores become lower and those of visually impaired children become equal to sighted children with age. The results of our study may help the children's entourage to better adapt their interactions in a context of visual impairment.

In this paper, we wanted to verify the hypothesis that extruding cartographic symbols on tactile maps to different heights might allow reducing the minimum (suggested in the literature) horizontal distances between them, without impacting the overall map's legibility. This approach might allow preparing tactile maps in smaller scales and thus, reducing production cost, or putting additional spatial information on the same map sheet that would not fit otherwise. To verify the hypothesis we have prepared 6 different stimuli variants with or without height differentiation applied and different horizontal distances between tactile symbols adopted (1 mm, 2 mm and 3 mm). In the controlled study sessions with 30 participants with visual impairments we have measured the times required for solving 3 different spatial tasks on 3D printed tactile stimuli. We have also performed qualitative analysis to learn participants' opinions about the proposed design and materials used. It turns out that applying height differentiation not only results in shorter times required for solving spatial tasks but is also considered by blind individuals as a convenient improvement in terms of use comfort and allows reduction of recommended minimum horizontal distances between symbols on tactile maps.

BACKGROUND: Knowledge about self-efficacy and its significance for the quality of life of people with visual impairment is lacking. The aims of the study were to compare general self-efficacy in individuals with visual impairment with the general population, and to investigate the association between self-efficacy and life satisfaction. METHODS: A telephone-based cross-sectional survey was conducted between January and May 2017 in a probability sample of adults who were members of the Norwegian Association of the Blind and Partially Sighted. Participants were asked questions about their sociodemographic characteristics, characteristics of vision loss, general self-efficacy (General Self-efficacy Scale), and life satisfaction (Cantril's Ladder of Life Satisfaction). We obtained norm data from a representative survey of the general Norwegian population (N = 1792; mean age 53.2 years; 52.5% females). RESULTS: People with visual impairment had higher levels of general self-efficacy than people in the general population (Mean: 31.5 versus 29.0, p < .001). Results from linear regression analyses of the visual impairment population showed that higher education and residential in an urban municipality were associated with higher self-efficacy. Having additional impairments and a previous history of physical or sexual assaults were associated with lower self-efficacy. A linear dose-response relationship was found between self-efficacy and life satisfaction, in the visual impairment population as well as in the general population. CONCLUSIONS: People with visual impairment have higher self-efficacy than people in the general population, possibly due to extensive mastery experience in how to handle life as visually impaired. Self-efficacy seems to be important in achieving the best possible life.

Understanding the factors that determine if a person can successfully learn a novel sensory skill is essential for understanding how the brain adapts to change, and for providing rehabilitative support for people with sensory loss. We report a training study investigating the effects of blindness and age on the learning of a complex auditory skill: click-based echolocation. Blind and sighted participants of various ages (21-79 yrs; median blind: 45 yrs; median sighted: 26 yrs) trained in 20 sessions over the course of 10 weeks in various practical and virtual navigation tasks. Blind participants also took part in a 3-month follow up survey assessing the effects of the training on their daily life. We found that both sighted and blind people improved considerably on all measures, and in some cases performed comparatively to expert echolocators at the end of training. Somewhat surprisingly, sighted people performed better than those who were blind in some cases, although our analyses suggest that this might be better explained by the younger age (or superior binaural hearing) of the sighted group. Importantly, however, neither age nor blindness was a limiting factor in participants' rate of learning (i.e. their difference in performance from the first to the final session) or in their ability to apply their echolocation skills to novel, untrained tasks. Furthermore, in the follow up survey, all participants who were blind reported improved mobility, and 83% reported better independence and wellbeing. Overall, our results suggest that the ability to learn click-based echolocation is not strongly limited by age or level of vision. This has positive implications for the rehabilitation of people with vision loss or in the early stages of progressive vision loss.

ABSTRACT Introduction: Physical exercise can bring important benefits in the areas of physical and psychological health and behavioral aspects. However, there have been few studies that link physical exercise and sleep in people with disabilities. Objective: This study aims to analyze the benefits promoted by swimming in the health and quality of sleep of visually impaired people of different levels of physical fitness. Methods: Thirty male volunteers, visually impaired, aged 16-60 years, took part in the study. The volunteers were divided into three groups: irregularly active (G1), swimming twice a week (G2), and swimming five times a week (G3). Questionnaires related to sleep pattern (Pittsburgh), sleepiness (Epworth), chronotype (Horne and Östberg) and quality of life (SF-36) were applied. Results: The main results showed that G3 presented better quality of sleep, as well as more effective sleep, compared to the other two groups. In addition, G1 showed poorer scores for quality of life compared to G3 in the domains general health, vitality, and social aspect. Conclusion: We suggest that more frequent physical activity (swimming) has a positive effect on quality of sleep and quality of life of people with visual impairments. Level of evidence III, case control study .
RESUMEN Introducción: La práctica del ejercicio físico puede traer beneficios importantes en el ámbito físico, psicológico y comportamental. Sin embargo, la literatura es escasa al relacionar ejercicio físico y sueño en las personas con discapacidad. Objetivo: Este estudio tuvo como objetivo analizar los beneficios que la natación promueve en la salud y en la calidad del sueño de discapacitados visuales con diferentes niveles de aptitud física. Métodos: Participaron en la investigación 30 voluntarios del sexo masculino, discapacitados visuales, con edad entre 16 y 60 años, divididos en tres grupos, a saber, irregularmente activos (G1), practicantes de natación 2 veces por semana (G2) y practicantes de natación 5 veces por semana (G3). Fueron aplicados los cuestionarios relacionados con el patrón de sueño (Pittsburgh), somnolencia (Epworth), cronotipo (Horne y Östberg) y calidad de vida (SF-36). Resultados: Los principales resultados mostraron que G3 presentó mejor calidad de sueño, bien como mayor eficiencia del sueño con relación a los otros dos grupos. Además, G1 demostró peores puntajes para calidad de vida con relación a G3 en los dominios estado general de salud, vitalidad y aspecto social. Conclusión: De esa forma, podemos sugerir que la frecuencia mayor en la práctica de actividad física (natación) actuó positivamente sobre la calidad del sueño y la calidad de vida de las personas con discapacidad visual. Nivel de evidencia III; Estudio de caso control .
RESUMO Introdução: A prática do exercício físico pode trazer benefícios importantes no âmbito físico, psicológico e comportamental. No entanto, a literatura é escassa ao relacionar exercício físico e sono nas pessoas com deficiência. Objetivo: Este estudo teve como objetivo analisar os benefícios que a natação promove na saúde e na qualidade do sono de deficientes visuais com diferentes níveis de aptidão física. Métodos: Participaram da pesquisa 30 voluntários do sexo masculino, deficientes visuais, com idade entre 16 e 60 anos distribuídos em três grupos, a saber, irregularmente ativos (G1), praticantes de natação 2 vezes por semana (G2); e praticantes de natação 5 vezes na semana (G3). Foram aplicados os questionários relacionados ao padrão de sono (Pittsburgh), sonolência (Epworth), cronotipo (Horne e Östberg) e qualidade de vida (SF-36). Resultados: Os principais resultados mostraram que o G3 apresentou melhor qualidade de sono, bem como maior eficiência do sono com relação aos outros dois grupos. Além disso, o G1 demonstrou piores escores para qualidade de vida com relação ao G3 nos domínios estado geral de saúde, vitalidade e aspecto social. Conclusão: Dessa forma, podemos sugerir que a frequência maior na prática da atividade física (natação) atuou positivamente sobre a qualidade do sono e a qualidade de vida de pessoas com deficiência visual. Nível de evidência III, Estudo de caso controle .

OBJECTIVES: The objective of this study was to offer an overview of literature relating to the topic of arts as activity within the context of military and veteran health and to consider the implications of current knowledge on future research with visually impaired veterans. STUDY DESIGN: A search for literature addressing the topic of visual art activities with visually impaired veterans was undertaken. No research addressing this topic was identified. A review of literature on the related topics of mental health and well-being in military veterans, visual impairment and mental health and well-being, and art therapy for veteran populations was carried out to offer an overview of current knowledge. RESULTS: While there is growing evidence of the benefits of arts engagement among both general and military populations, the role of the visual arts in the everyday lives of broader veteran samples, and the impact of these activities on holistic well-being, remains underexplored. The current article highlights the need for art as activity to be differentiated from art as therapy and argues that the former might offer a tool to positively impact the holistic well-being of visually impaired veterans. CONCLUSIONS: Future research relating to the use of visual art activities in the context of veteran health and well-being should endeavour to explore the potential impacts of engagement on holistic well-being. Research is needed to build on anecdotal evidence of the positive impact of arts engagement on visually impaired veterans by systematically exploring if, and how, holistic well-being in this population may be impacted by engagement with visual art activities.

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.

PURPOSE: This study aimed to understand and describe the diabetes self-management experience of visually impaired people with diabetes. METHODS: Ten participants were recruited through a website used by the visually impaired from February to March 2020. Data were collected through two focus group interviews conducted in June 2020; each group consisted of five participants. All interviews were recorded with the consent of the participants and transcribed verbatim. The transcribed data were analyzed using qualitative content analysis. RESULTS: Seven categories were as follows; a two-faced, lifelong companion, an unprepared encounter, struggle to live, love-hate relationship with family, strategies to adapt, lessening attention to self-management, the desire to learn properly. CONCLUSION: It can be concluded that the visually impaired have fewer opportunities for receiving diabetes self-management education than general diabetic patients. Consequently, plans to improve the education available to such patients are required. Additionally, psychological counseling and diabetes education for patients' families are necessary, and improving the perception of medical workers regarding the visually impaired will be prove useful.
