Un análisis integrado entre la calidad de vida y las necesidades de apoyo de personas adultas con discapacidad intelectual en Chile / An integrated analysis between the quality of life and the support needs of adults with intellectual disabilities in Chile

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

The support paradigm and the quality of life paradigm have become fundamental guides for progress in the field of Intellectual Disability (ID). Based on a sample of 93 adults with ID, the relationship between Quality of Life and Support Needs is analyzed from a non-experimental quantitative approach, applying the INICO-FEAPS scale and the SIS Support Intensity scale for each construct. The main results show that there is a strong and indirect relationship between quality of life and support needs, and the relevance of analyzing these results from variables such as the degree of disability, sex or socioeconomic level. The discussion allows us to infer the need to discuss new strategies around categories such as the degree of disability, self-determination and social inclusion, as facilitating elements of quality of life and supporting a comprehensive approach that contributes to the development of social program strategies for the population with ID.

Diet and omega-3 and vitamin D supplement use predict five-year fatigue and disability trajectories in people with multiple sclerosis.

BACKGROUND: Fatigue and disability are indicators of disease progression experienced by many people with multiple sclerosis (pwMS). Understanding trajectories of these outcomes, and their predictors, may provide insight to potential interventions for MS management. METHODS: Survey data from 839 pwMS from the Health Outcomes and Lifestyle in pwMS study were analysed. Fatigue was defined as mean Fatigue Severity Scale >5, and severe disability as Patient Determined Disease Steps >5. Group-based trajectory modelling was used to identify fatigue and disability trajectories over five-years. Dietary predictors associated with outcome trajectory group membership were assessed using log-binomial regression. Demographic and clinical characteristics were considered in multivariable models. RESULTS: Distinct trajectories for fatigue and disability were identified. For fatigue, 58 % of pwMS were assigned to low-, and 42 % to high-, fatigue trajectory groups. For disability, 85 % of pwMS were assigned to low-, and 15 % to high-, disability groups. Baseline high-quality diet, and omega-3 and vitamin D supplement use, were associated with reduced risk of being in high-fatigue and high-disability trajectories, while meat and dairy consumption were associated with increased risk. CONCLUSIONS: A high-quality diet, avoiding meat and dairy, and omega-3 and vitamin D supplement use, individually predict better fatigue and disability trajectories. Dietary modifications should be considered in MS management.

Neuroprotective Effects of the Nutraceutical Dehydrozingerone and Its C2-Symmetric Dimer in a Drosophila Model of Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disorder characterized by the loss of dopaminergic neurons responsible for unintended or uncontrollable movements. Mutations in the leucine-rich repeat kinase 2 locus contribute to genetic forms of PD. The fruit fly Drosophila melanogaster carrying this mutation (LRRK2-Dm) is an in vivo model of PD that develops motor impairment and stands for an eligible non-mammalian paradigm to test novel therapeutic approaches. Dehydrozingerone (DHZ) is a natural phenolic compound isolated from ginger and presents anti-inflammatory, antioxidant and neuroprotective properties, making it a potential therapeutic target for PD. We administered DHZ and its C2-symmetric dimer (DHZ-DIM) at 0.5 and 1 mM for 14 and 21 days in the LRRK2-Dm, with the aim of assessing changes in rescuing motor behavior, brain dopaminergic neurons, mitochondria and synapses (T-bars). The shorter treatment with both molecules revealed efficacy at the higher dose, improving climbing behavior with a prevention of dopaminergic neuronal demise. After 21 days, a recovery of the motor disability, dopaminergic neuron loss, mitochondrial damage and T-bars failure was observed with the DHZ-DIM. Our data indicate that the DHZ-DIM exerts a more potent neuroprotective effect with respect to the monomer in LRRK2-Dm, prompting further investigation of these compounds in rodent models of PD.

Implementation and Challenge of Supported Employment for People With Disabilities in China.

The Chinese government initiated a pilot program to implement supported employment for people with disabilities in 2014. Since then, policies have been enacted to promote supported employment. This study explored how practitioners understand and implement supported employment for people with disabilities in China. It was found that non-governmental service organizations have mainly implemented supported employment with financial support provided by local disabled persons' federations; without a governmental guide, the small-scale folk practice presented many difficulties and unstable factors. Results indicated that the Chinese government should actively establish and improve the supported employment system and further expand supported employment practices at the governmental level.

Predictive models for perceived convenience of accessing outdoor activities among elderly with physical disabilities in rural China.

BACKGROUND: The elderly, especially those with physical disabilities, often encounter barriers that prevent them from accessing outdoor activities. Their perceptions of the convenience of accessing outdoor activities may be influenced by various factors including their health, the social context, and/or planned behavior. This study aimed to develop predictive models that identify the principal determinants of perceived convenience among this demographic, and it also examined the disparities observed between genders. METHODS: This was a cross-sectional survey of 1216 community-dwelling older people with physical disabilities in rural China. Grounded on the rehabilitation concepts and the theory of planned behavior, structural equation models integrated health and social behavior factors were constructed to predict perceived convenience of accessing outdoor activities. The standardized coefficients explained the contributions of various factors to the variance. RESULTS: The final structural models demonstrated good fit for both female and male participants. Perceptions of the convenience of accessing outdoor activities among both women and men were directly impacted by their physical functioning and their intention to participate, and indirectly by medical expenditure, subjective norms, pain, and role limitation in emotional interactions. Positive mental health was more influential for women, while men were more influenced by subjective norms. CONCLUSIONS: Structural equation models have effectively predicted the self-reported convenience of accessing outdoor activities, underscoring the importance of functional and behavioral rehabilitation. Furthermore, gender-sensitive rehabilitation programs are advised to promote engagement in outdoor activities among elderly individuals with physical disabilities.

Physical and Rehabilitation Medicine: say relational or functional, not holistic.

Modern medicine tends to privilege disciplines promising "objective" laws governing body parts (from molecules to organs). Studies on a person's illness and disability are (apparently) confined to "subjectivity." The Specialty of Physical and Rehabilitation Medicine is often regarded as a humanitarian approach, belonging at best to the family of "soft," "qualitative," or "quasi-experimental" sciences. This specialty often claims specificity by labelling itself as "functional" and "holistic." However, it is shown here that the former term is acceptable, yet redundant, and the second misleading. When human behaviors and perceptions are at stake, "function" indicates a person's relationship with the outer world (already tackled by the definitional term "physical" from the Greek "physis"). The word "holistic" emphasizes mind-body unity and person-environment interdependence but, in current usage, overshadows the complementary need for an analytic, experimental approach to any function. Medicine aims at fighting disease and disability in single persons. This endeavor requires knowing body parts and mechanisms and understanding how interventions on "parts" affect the "whole." This understanding rests on the experimental method. For instance, returning to a given societal role (participation) may require restoration of walking (activity), which may require reinforcement of weakened muscular groups (impairment). Working only on holistic bio-psycho-social "wholes" may miss the therapeutic mission of medicine.

Improvements in nutrition knowledge among adults with physical disabilities: A program evaluation of the mindfulness, exercise, and nutrition to optimize resilience (MENTOR) program 2020-2021.

BACKGROUND: The Centers for Disease Control and Prevention (CDC) funds a quality improvement (QI) health promotion telewellness program for adults with physical disabilities. OBJECTIVE: The nutrition component of the parent program, Mindfulness, Exercise, and Nutrition to Optimize Resilience (MENTOR) program, from 2020 to 2021, was evaluated to assess changes in nutrition knowledge of people with physical disabilities. METHODS: This was a quasi-experimental program evaluation by pre-post survey of participating adults with physical disabilities. Participants attended weekly nutrition classes for eight weeks with optional one-on-one counseling with a Registered Dietitian. Participants completed pre-post General Nutrition Knowledge Questionnaire Revised (GNKQ-R) that were analyzed using paired t-tests. Participants were grouped into quartiles by pre-program GNKQ-R scores for additional comparisons. Program attendance and post-program feedback were also evaluated. RESULTS: A total of 286 participants completed the MENTOR program, and 31% (n = 89) completed pre-post questionnaires for data analysis. Mean pre-program GNKQ-R scores were 58.4 ± 15.1 and post scores were 64.4 ± 11.3, which demonstrated a statistically significant improvement in nutrition knowledge (p < .001). Ancillary analysis revealed that participants with the lowest quartile of pre-program nutrition knowledge had the greatest improvements in their post-GNKQ-R scores (Mean change 16.4 ± 13.9). Questionnaire data revealed participants' subjective knowledge changes and their feedback on the nutrition component of the program. CONCLUSIONS: The eight-week MENTOR program effectively improved nutrition knowledge among people with physical disabilities. This demonstrates the impact the program can have on individual knowledge levels. Additionally, these results support the implementation of the program to the broader population of people with disabilities.

Aspiring to Disability Consciousness in Health Professions Training.

Lack of disability-competent health care contributes to inequitable health outcomes for the largest minoritized population in the world: persons with disabilities. Health care professionals hold implicit and explicit bias against disabled people and report receiving inadequate disability training. While disability competence establishes a baseline standard of care, health professional educators must prepare a disability conscious workforce by challenging ableist assumptions and promoting holistic understanding of persons with disabilities. Future clinicians must recognize disability as an aspect of diversity, express respect for disabled patients, and demonstrate flexibility about how to care for disabled patients' needs. These skills are currently undervalued in medical training, specifically. This article describes how integrating disability consciousness into health professions training can improve health equity for patients with disabilities.

Description of an interdisciplinary, holistic cognitive rehabilitation program for adults with mild to moderate cognitive impairment after acquired brain injury.

PURPOSE: Cognitive rehabilitation research has progressed slowly, in part due to incomplete reporting of intervention content and delivery and the difficulties this produces for discerning program effectiveness. This knowledge gap can be reduced by providing detailed intervention descriptions. We document the content/ingredients and therapeutic targets of a cognitive rehabilitation program for adults with mild-to-moderate cognitive impairment. METHODS: The documentation process used a method of participatory/collaborative research. Discussions with the clinical team identified session content/ingredients and therapeutic targets, which were then described using Body Functions, and Activities & Participation domains from the International Classification of Function, Disability and Health (ICF). Domains most frequently targeted by each clinician were identified as Primary Targets. RESULTS: Each clinician produced a detailed description of session content, implementation, and ICF-coded therapeutic targets. This revealed that the whole program targets 29 ICF domains, seven of which were identified as Primary Targets: Higher-level Cognitive; Attention; Memory; Emotional; Global Psychosocial, Temperament and Personality, and Conversation. CONCLUSIONS: Documentation of treatment targets enabled identification of appropriate outcome measures which are now being used to investigate program efficacy. This step-by-step explanation of the documentation process could serve as a guide for other teams wanting to document their rehabilitation interventions and/or establish similar programs.IMPLICATIONS FOR REHABILITATIONIncomplete reporting of intervention content and delivery contributes to difficulties in discerning the effectiveness of complex rehabilitation programs.Current recommendations for rehabilitation intervention reporting suggest that these difficulties can be partially overcome by providing detailed descriptions of intervention content/ingredients and treatment targets.Human and physical resources differ widely from one clinical setting to another and the existence of clear program descriptions can guide clinicians who wish to create similar programs.Detailed descriptions of rehabilitation interventions are necessary to accurately measure patient outcomes and generate testable hypotheses about proposed mechanisms of action.Program descriptions are needed for the development of treatment theories and the advancement of evidence-based practice in rehabilitation.

Nutritional Support System (NSS) as a New Therapeutic Strategy for Cerebral Palsy.

Cerebral palsy (CP) is part of a group of nonprogressive motor disorders. The disease affects movement and posture and constitutes the most frequent cause of motor disability in childhood. CP is characterized by spasticity, reflecting lesions in the pyramidal pathway. Treatment is currently focused on physical rehabilitation, and the annual progression of the disease is 2-3%. About 60% of these patients present severe degrees of malnutrition associated with dysphagia, gastrointestinal abnormalities, malabsorption, increased metabolism, and depression. These alterations promote sarcopenia functional dependence and affect the quality of life and delay the evolution of motor skills. Currently, there is evidence that the supplementation of several nutrients, dietary correction, and probiotics can improve neurological response by stimulating neuroplasticity, neuroregeneration, neurogenesis, and myelination. This therapeutic strategy could shorten the response period to treatment and increase both gross and fine motor skills. The interaction of nutrients and functional foods integrating a Nutritional Support System (NSS) has shown greater efficiency in neurological stimulation than when nutrients are supplied separately. The most studied elements in the neurological response are glutamine, arginine, zinc, selenium, cholecalciferol, nicotinic acid, thiamine, pyridoxine, folate, cobalamin, Spirulina, omega-3 fatty acids, ascorbic acid, glycine, tryptophan, and probiotics. The NSS represents a therapeutic alternative that will restore neurological function in patients with spasticity and pyramidal pathway lesions, both characteristics of patients with CP.

The relationship between sensory impairment and home care client's received care time-A cross-sectional study.

AIM: The aim of this study was to explore the relationship between sensory impairment and home care client's received care time. DESIGN: A cross-sectional multi-source study. METHODS: Data from a self-reported staff survey on care time allocation were merged with registry data from the Resident Assessment Instrument registry (n = 1477). The data were collected during 1 week from 17 home care units in Finland in October 2021. The relationship between sensory impairment and clients received care time was examined using linear regression analyses. RESULTS: The linear regression analyses showed that having vision impairment alone increased care time, while dual sensory impairment resulted in decreased received care time. Hearing impairment alone was not statistically significantly associated with care time. CONCLUSION: The holistic care need of home care clients with dual sensory impairment may not be adequate. To ensure equality and the individually tailored care of clients, further attention must be paid to clients with sensory impairments, especially those with dual sensory impairment. Furthermore, the competence of home care workers to encounter and communicate with clients with sensory impairment must be developed to support the holistic care. IMPLICATIONS FOR THE PATIENT CARE: The sensory impairments of home care clients must be identified in time and considered in care planning and encountering clients. IMPACT: As there is a risk that clients with dual sensory impairment are not able to fully express themselves, it is imperative that further attention is paid to clients with sensory impairments, to better understand and support this vulnerable group. Increased awareness and continuous education are needed to better identify and support home care clients with sensory impairment. REPORTING METHOD: The study adheres to the STROBE reporting guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Care coordination for children with a disability or developmental difficulty: Empowers families and reduces the burden on staff supporting them.

BACKGROUND: Almost half of all children and young people with a disability or developmental difficulty (DDD) have complex disability and are likely to require multidisciplinary care. Care coordination (CC) aims to provide a single point of contact and a coordinated service, thereby improving care experiences, meeting unmet needs and empowering families. The impact of CC for children with DDD was evaluated. METHOD: Between May and August 2020, an in-depth evaluation of CC in Gwent, South Wales was conducted. Of 284 families who accessed CC, 38 were approached, as well as 177 health and social care professionals based at Serennu, Nevill Hall and Caerphilly Children's Centres. Nine families and 14 professionals completed semi-structured interviews. Interview transcripts were analysed using thematic analysis. RESULTS: This evaluation found perceived improvements in families' abilities to navigate, organize and understand care and increased parental engagement. Professionals observed fewer missed appointments, and both professionals and families described CC as a source of holistic support, including practical advice regarding housing, finances and emotional support. Professionals commented on CC easing pressure on their service. Potential limitations included restricted staff capacity and the role not being defined clearly for families and professionals. CONCLUSIONS: At a time of increased stress for families of children with DDD, and scarce resources to support them, care coordinators play a vital role in assisting families to engage with health services, while feeling supported and empowered. CC reduces the burden on professionals, while enhancing relationships with families.

The Bobath Clinical Reasoning Framework: A systems science approach to the complexity of neurodevelopmental conditions, including cerebral palsy.

The current recommended developmental Bobath practice within the Bobath Clinical Reasoning Framework (BCRF) can be conceptualized using the lens of systems science, thereby providing a holistic perspective on the interrelatedness and interconnectedness of the variables associated with childhood-onset disability. The BCRF is defined as an in-depth clinical reasoning framework that can be applied to help understand the relationships between the domains of the International Classification of Functioning, Disability and Health, how those domains can be influenced, and how they impact each other. The BCRF is a transdisciplinary observational system and practical reasoning approach that results in an intervention plan. This provides a holistic understanding of the complexity of situations associated with disorders such as cerebral palsy (CP) and the basis for the lifelong management and habilitation of people living with neurological disorders. The clinical reasoning used by the BCRF draws on the important contextual factors of the individual and their social environment, primarily the family unit. It is rooted in an understanding of the interrelationships between typical and atypical development, pathophysiology (sensorimotor, cognitive, behavioural), and neuroscience, and the impact of these body structure and function constructs on activity and participation. The systems science model integral to the BCRF is a useful way forward in understanding and responding to the complexity of CP, the overarching goal being to optimize the lived experience of any individual in any context.

Evaluation of online adaptive yoga for psychological well-being in adults with disabilities.

PURPOSE/OBJECTIVE: The present study examined the preliminary effectiveness of an online, community-based adaptive yoga program on mindfulness, social connectedness, life satisfaction, and communicative participation. RESEARCH METHOD/DESIGN: Adults (N = 48) were from a U.S. Midwest rehabilitation program and modally identified as White (73%), women (68%), and in their 30s (24%). One-third (35%) of participants were able to walk independently, and cerebral palsy was the most common primary disability diagnosis (32%). The 90-min adaptive yoga program and assessments were offered online weekly for 6 weeks, in which data from 29 participants across three sessions were included in the present analyses. RESULTS: Regarding our primary outcome of interest, there was a statistically significant positive increase in mindfulness over time, F(1, 28) = 5.66, p = .02, with a strong effect size, d = 2.43. All secondary variables had statistically nonsignificant changes over time, although with large effect sizes: social connectedness (d = 0.77), life satisfaction (d = 0.92), and communicative participation (d = 0.40). CONCLUSIONS/IMPLICATIONS: The present study provides support for well-being programs for an underserved group; specifically, an online adaptive yoga program with routine outcome monitoring assessments has preliminary effectiveness in increasing mindfulness. Consideration of such well-being programs alongside insurance would be an important policy consideration. Further controlled research is necessary to draw decisive conclusions.

A Systematic Review of Telehealth-Based Pediatric Cancer Rehabilitation Interventions on Disability.

Background: Telehealth is an emerging method which may overcome barriers to rehabilitation access for pediatric cancer survivors (aged ≤19 years). This systematic review aimed to examine telehealth-based rehabilitation interventions aimed at preventing, maintaining, or improving disability in pediatric cancer survivors. Methods: We performed systematic searches in Ovid MEDLINE, Ovid EMBASE, Cochrane Library, SCOPUS, Web of Science, and CINAHL Plus between 1994 and 2022. Eligible studies included telehealth-based interventions assessing disability outcomes in pediatric cancers. Results: Database searches identified 4,040 records. Nine unique interventions met the eligibility criteria. Telehealth delivery methods included telephone (n = 6), email (n = 3), mobile health applications (n = 3), social media (n = 3), videoconferencing (n = 2), text messaging (n = 2), active video gaming (n = 2), and websites (n = 2). Interventions focused on physical activity (n = 8) or self-management (n = 1). Outcomes assessing disability varied (n = 6). Three studies reported statistically and clinically significant results. Narrative synthesis of findings was constructed based on the Picker's principles for patient-centered care: (1) values, preferences, and needs; (2) involve family and friends; (3) coordination of care; (4) provide social support; (5) holistic well-being; and (6) information and communication. Conclusions: Telehealth-based rehabilitation interventions for pediatric cancer survivors is an emerging research area with potential to improve disability outcomes. Adequately powered trials with consistency in disability outcome measures are warranted. Additional research is needed to determine the effectiveness and best practices for telehealth-based pediatric cancer rehabilitation.

Characteristics of Canadians Living With Long-Term Health Conditions or Disabilities Who Had Unmet Rehabilitation Needs During the First Wave of the COVID-19 Pandemic: A Cross-sectional Study.

OBJECTIVE: This study aimed to describe the characteristics associated with unmet rehabilitation needs in a sample of Canadians with long-term health conditions or disabilities during the first wave of the COVID-19 pandemic. DESIGN: We used data from the Impacts of COVID-19 on Canadians Living With Long-Term Conditions and Disabilities, a national cross-sectional survey with 13,487 respondents. Unmet needs were defined as needing rehabilitation (ie, physiotherapy/massage/chiropractic, speech therapy, occupational therapy, counseling services, or support groups) but not receiving due to the pandemic. We used multivariable modified Poisson regression to examine the association between demographic, socioeconomic, and health-related characteristics and unmet rehabilitation needs. RESULTS: More than half of the sample were 50 years and older (52.3%), female (53.8%), and 49.3% reported unmet rehabilitation needs. Those more likely to report unmet needs were females, those with lower socioeconomic status (receiving disability benefits or social assistance, job loss, increased work hours, decreased household income or earnings), and those with lower perceived general health or mental health status. CONCLUSIONS: Among Canadians with disabilities or chronic health conditions, marginalized groups are more likely to report unmet rehabilitation needs. Understanding the systemic and upstream determinants is necessary to develop strategies to minimize unmet rehabilitation needs and facilitate the delivery of equitable rehabilitation services.

Smoking cessation interventions for U.S. adults with disabilities: A systematic review.

INTRODUCTION: People with disabilities disproportionately use tobacco products. However, little is known about cessation interventions tailored for people with disabilities. The objective of this study was to conduct a systematic review of smoking cessation interventions for adults with disabilities. METHODS: Six electronic databases (Cochrane, CINAHL Plus [EBSCOhost], Embase [Ovid], Medline [Ovid], PsycINFO [Ovid], and Web of Science) were searched to identify eligible interventions for people with disabilities (e.g., vision, hearing, mobility, communication, cognition, self-care) through July 2023. Two independent coders evaluated the records and extracted data from studies that met inclusion criteria. Qualitative synthesis was conducted on the included studies in 2023. RESULTS: One randomized controlled trial and one nonrandomized study met the inclusion criteria. Both studies used mindfulness-based procedures to reduce cigarette use in adults with mild intellectual disability. The outcome was defined as self-reported cigarette use at follow-up, which ranged from 1 year to 3 years. Limited information was provided on how the interventions were tailored to meet the unique needs of people with disabilities in either study. CONCLUSION: Two interventions conducted in adults with mild intellectual disability showed promising results using mindfulness-based procedures; however, the studies did not address barriers reported by people with disabilities, nor tailor the interventions to meet the needs of the target population. Research is needed to address tobacco use disparities among people with a range of disabilities. Current cessation interventions would be enhanced by integrating disability identifiers alongside other demographic information in future studies and reporting subgroup analyses in adults with disabilities.

Low serum 25­hydroxy-vitamin D levels are associated with cognitive impairment in multiple sclerosis.

BACKGROUND: Cognitive impairment frequently affects people with multiple sclerosis (MS). Low vitamin D has been associated with cognitive dysfunction in different neurodegenerative diseases, and, in MS, with motor disability and disease activity. We aim to investigate associations between vitamin D and cognitive status in MS. METHODS: In this cross-sectional study, we included 181 MS patients, recruited consecutively at the MS Unit of the Policlinico Federico II University Hospital of Naples, Italy, between January and April 2022, with serum 25­hydroxy (25-OH) vitamin D measurements using Chemiluminescence-ImmunoAssay, and cognitive assessment using the Brief International Cognitive Assessment for MS (BICAMS), which includes Symbol Digit Modalities Test (SDMT), California Verbal Learning Test-II (CVLT-II) and Brief Visuospatial Memory Test-Revised (BVMT-R). We collected demographics (age, sex, education), and clinical variables (disease duration, disease subtype, expanded disability status scale (EDSS), disease modifying treatment, relapses in previous 12 months, vitamin D supplementation, comorbidities). For a subset of patients (n = 41, 23.2% of the total sample), we collected Beck Depression Inventory-II, Beck Anxiety Inventory, and Modified Fatigue Impact Scale. RESULTS: At univariable linear regression models, serum 25-OH-vitamin D levels were 0.9 ng/mL higher for each unit increase of SDMT adjusted scores (Coeff=0.93; 95%CI=0.81, 1.04; p<0.01), 0.7 ng/mL higher for each unit increase of CVLT-II adjusted scores (Coeff=0.68; 95%CI=0.53, 0.83; p<0. 01), 0.6 ng/mL higher for each unit increase of BVMT-R adjusted scores (Coeff=0.58; 95%CI=0.43, 0.73; p<0.01), -9.63 ng/mL lower for each impaired BICAMS test (Coeff=-9.63; 95%CI=-11.48, -7.79; p<0.01), and -2.2 ng/mL lower for each unit increase of EDSS (Coeff=-2.16; 95%CI=-3.57, -0.75; p<0.01). At multivariable linear regression models, we confirmed associations between 25-OH-vitamin D and EDSS (Coeff=-2.09; 95%CI=-4.45, -0.43; p<0.01), SDMT (Coeff=0.75; 95%CI=0.60, 0.90; p<0.01), and CVLT-II (Coeff=0.14; 95%CI=0.01, 0.28; p = 0. 04). Results remained unchanged when including depression, anxiety and fatigue scores. CONCLUSIONS: Lower serum 25-OH-vitamin D was associated with worse cognitive function in MS. Future studies should consider longitudinal variations in cognitive function in relation to vitamin D supplementation.
