RESUMEN

Physical activity improves the well-being of persons living with dementia but few exercise programs include them. The Dementia-Inclusive Choices for Exercise (DICE) toolkit aims to improve exercise providers' understanding of dementia and ability to support persons living with dementia in physical activity. We evaluated the co-designed DICE toolkit with exercise providers using a mixed-methods approach comprising pre/post questionnaires and interviews and reflection diaries. Among 16 participants, self-efficacy for exercise delivery to persons living with dementia and both knowledge and attitudes toward dementia significantly improved. Thematic analysis suggested participants (a) had a deeper understanding of the variability of dementia, (b) were planning for equitable access for persons living with dementia, (c) planned to promote social connection through exercise, and (d) were optimistic for future engagement with persons living with dementia. The DICE toolkit may improve exercise providers' knowledge and confidence to plan proactively to support persons living with dementia in programs and services.

RESUMEN

BACKGROUND: The growth of urban dwelling populations globally has led to rapid increases of research and policy initiatives addressing associations between the built environment and physical activity (PA). Given this rapid proliferation, it is important to identify priority areas and research questions for moving the field forward. The objective of this study was to identify and compare research priorities on the built environment and PA among researchers and knowledge users (e.g., policy makers, practitioners). METHODS: Between September 2022 and April 2023, a three-round, modified Delphi survey was conducted among two independent panels of international researchers (n = 38) and knowledge users (n = 23) to identify similarities and differences in perceived research priorities on the built environment and PA and generate twin 'top 10' lists of the most important research needs. RESULTS: From a broad range of self-identified issues, both panels ranked in common the most pressing research priorities including stronger study designs such as natural experiments, research that examines inequalities and inequities, establishing the cost effectiveness of interventions, safety and injuries related to engagement in active transportation (AT), and considerations for climate change and climate adaptation. Additional priorities identified by researchers included: implementation science, research that incorporates Indigenous perspectives, land-use policies, built environments that support active aging, and participatory research. Additional priorities identified by knowledge users included: built environments and PA among people living with disabilities and a need for national data on trip chaining, multi-modal travel, and non-work or school-related AT. CONCLUSIONS: Five common research priorities between the two groups emerged, including (1) to better understand causality, (2) interactions with the natural environment, (3) economic evaluations, (4) social disparities, and (5) preventable AT-related injuries. The findings may help set directions for future research, interdisciplinary and intersectoral collaborations, and funding opportunities.

RESUMEN

CONTEXTE: Au Canada, plus de 2 millions de personnes vivent avec l'ostéoporose, une maladie qui accroît le risque de fracture, ce qui fait augmenter la morbidité et la mortalité, et entraîne une perte de qualité de vie et d'autonomie. La présente actualisation des lignes directrices vise à accompagner les professionnelles et professionnels de la santé au Canada dans la prestation de soins visant à optimiser la santé osseuse et à prévenir les fractures chez les femmes ménopausées et les hommes de 50 ans et plus. MÉTHODES: Le présent document fournit une actualisation des lignes directrices de pratique clinique de 2010 d'Ostéoporose Canada sur le diagnostic et la prise en charge de l'ostéoporose au pays. Nous avons utilisé l'approche GRADE (Grading of Recommendations Assessment, Development and Evaluation) et effectué l'assurance de la qualité conformément aux normes de qualité et de présentation des rapports de la grille AGREE II (Appraisal of Guidelines for Research & Evaluation). Les médecins de premier recours et les patientes et patients partenaires ont été représentés à tous les niveaux des comités et des groupes ayant participé à l'élaboration des lignes directrices, et ont participé à toutes les étapes du processus pour garantir la pertinence des informations pour les futurs utilisateurs et utilisatrices. Le processus de gestion des intérêts concurrents a été entamé avant l'élaboration des lignes directrices et s'est poursuivi sur toute sa durée, selon les principes du Réseau international en matière de lignes directrices. Dans la formulation des recommandations, nous avons tenu compte des avantages et des risques, des valeurs et préférences de la patientèle, des ressources, de l'équité, de l'acceptabilité et de la faisabilité; la force de chacune des recommandations a été déterminée en fonction du cadre GRADE. RECOMMANDATIONS: Les 25 recommandations et les 10 énoncés de bonne pratique sont répartis en sections : activité physique, alimentation, évaluation du risque de fracture, instauration du traitement, interventions pharmacologiques, durée et séquence du traitement, et monitorage. La prise en charge de l'ostéoporose devrait se fonder sur le risque de fracture, établi au moyen d'une évaluation clinique réalisée avec un outil d'évaluation du risque de fracture validé. L'activité physique, l'alimentation et la pharmacothérapie sont des éléments essentiels à la stratégie de prévention des fractures, qui devraient être personnalisés. INTERPRÉTATION: Les présentes lignes directrices ont pour but d'outiller les professionnelles et professionnels de la santé et la patientèle afin qu'ensemble ils puissent parler de l'importance de la santé osseuse et du risque de fracture tout au long de la vie adulte avancée. La détection et la prise en charge efficace de la fragilité osseuse peuvent contribuer à réduire les fractures et à préserver la mobilité, l'autonomie et la qualité de vie.

RESUMEN

BACKGROUND: In Canada, more than 2 million people live with osteoporosis, a disease that increases the risk for fractures, which result in excess mortality and morbidity, decreased quality of life and loss of autonomy. This guideline update is intended to assist Canadian health care professionals in the delivery of care to optimize skeletal health and prevent fractures in postmenopausal females and in males aged 50 years and older. METHODS: This guideline is an update of the 2010 Osteoporosis Canada clinical practice guideline on the diagnosis and management of osteoporosis in Canada. We followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework and quality assurance as per Appraisal of Guidelines for Research and Evaluation (AGREE II) quality and reporting standards. Primary care physicians and patient partners were represented at all levels of the guideline committees and groups, and participated throughout the entire process to ensure relevance to target users. The process for managing competing interests was developed before and continued throughout the guideline development, informed by the Guideline International Network principles. We considered benefits and harms, patient values and preferences, resources, equity, acceptability and feasibility when developing recommendations; the strength of each recommendation was assigned according to the GRADE framework. RECOMMENDATIONS: The 25 recommendations and 10 good practice statements are grouped under the sections of exercise, nutrition, fracture risk assessment and treatment initiation, pharmacologic interventions, duration and sequence of therapy, and monitoring. The management of osteoporosis should be guided by the patient's risk of fracture, based on clinical assessment and using a validated fracture risk assessment tool. Exercise, nutrition and pharmacotherapy are key elements of the management strategy for fracture prevention and should be individualized. INTERPRETATION: The aim of this guideline is to empower health care professionals and patients to have meaningful discussions on the importance of skeletal health and fracture risk throughout older adulthood. Identification and appropriate management of skeletal fragility can reduce fractures, and preserve mobility, autonomy and quality of life.

RESUMEN

OBJECTIVE: The purpose of this trial is to evaluate the effect of twice-weekly, moderate-to-high intensity progressive resistance training (PRT) for 1 year on lumbar spine bone mineral density (BMD) in individuals with low BMD, compared to attention control. Secondary analyses will examine if resistance training improves other health outcomes; if high intensity is more effective than moderate intensity resistance training for all outcomes; the cost of intervention versus benefit; the willingness to pay; and harms. METHODS: For this study, 324 men or postmenopausal women aged ≥50 years with a femoral neck, total hip, or lumbar spine BMD T-score of ≤-1, or a Fracture Risk Assessment Tool probability of ≥20% for major osteoporotic fracture or ≥ 3% for hip fracture are being recruited to participate in a randomized controlled trial with 1:1:1 randomization. Participants will be stratified by site (3 centers) to twice-weekly, supervised PRT at moderate intensity (about 10 repetitions maximum), to high intensity PRT (≤6 repetitions maximum), or to a home posture and balance exercise program (attention control) for 1 year (resistance training to comparator allocation ratio of 2:1). The primary outcome is lumbar spine BMD via dual-energy X-ray absorptiometry. Secondary outcomes include trabecular bone score, proximal femur and total hip BMD and structure, bone-free and appendicular lean mass, physical functioning, falls, fractures, glucose metabolism, cost per life-year gained, adverse events, and quality of life. Between-group differences will be tested in intention-to-treat and per-protocol analyses using analysis of covariance, chi-square tests, or negative binomial or logistic regression, adjusting for site and baseline values. IMPACT: The Finding the Optimal Resistance Training Intensity For Your Bones trial will support decision making on resistance training for people at risk of fracture.

RESUMEN

Persons with dementia have the right to equal inclusion in rehabilitation, including physical activity. However, the perspectives of persons with dementia are rarely integrated into decision-making related to physical activity programming, services, and supports. Here, we describe the participatory action research (PAR) approach used to develop the Dementia-Inclusive Choices for Exercise (DICE) toolkit, which aims to increase the quality and number of physical activity opportunities available to persons with dementia. The DICE Research Team included persons with dementia, a family care partner, exercise professionals, community and dementia service providers, health care professionals, and researchers who worked to: 1) Engage/maintain the Research Team; 2) Set/navigate ways of engagement; 3) Understand barriers to physical activity; 4) Prioritize the audience and actions; 5) Develop the toolkit; 6) Conduct usability testing; and 7) Implement and evaluate. Guided by the Behaviour Change Wheel, and informed by interviews, focus groups, and existing research, our PAR Team chose to prioritize training exercise providers; exercise providers can enable exercise for persons with dementia if they understand common changes with dementia and how to support persons with dementia in exercise. The content and format of the toolkit was co-developed: drafted by our Research Team, adapted through a stakeholder workshop, and refined through iterative development and usability testing. The product of our PAR process, the DICE toolkit, includes videos meant to destigmatize dementia, training modules and a training manual for exercise providers, a physical activity handout for persons with dementia, and wallet cards to help persons with dementia communicate their abilities, needs, and preferences. Our usability study indicated that the toolkit could be used by exercise providers and may improve attitudes about dementia. Our vision is that our co-developed DICE toolkit will empower exercise providers to improve physical activity opportunities and support for persons with dementia.

RESUMEN

OBJECTIVE: This project aimed to develop a virtual intervention for vertebral fractures (VIVA) to implement the international recommendations for the nonpharmacological management of osteoporotic vertebral fractures and to test its acceptability and usability. METHODS: VIVA was developed in accordance with integrated knowledge translation principles and was informed by the Behavioral Change Wheel, the Theoretical Domains Framework, and the affordability, practicability, effectiveness and cost-effectiveness, acceptability, side effects/safety, and equity (APEASE) criteria. The development of the prototype of VIVA involved 3 steps: understanding target behaviors, identifying intervention options, and identifying content and implementation options. The VIVA prototype was delivered to 9 participants to assess its acceptability and usability. RESULTS: VIVA includes 7 1-on-1 virtual sessions delivered by a physical therapist over 5 weeks. Each session lasts 45 minutes and is divided in 3 parts: education, training, and behavioral support/goal setting. Four main themes emerged from the acceptability evaluation: perceived improvements in pain, increased self-confidence, satisfaction with 1-on-1 sessions and resources, and ease of use. All of the participants believed that VIVA was very useful and were very satisfied with the 1-on-1 sessions. Four participants found the information received very easy to practice, 4 found it easy to practice, and 1 found it somewhat difficult to practice. Five participants were satisfied with the supporting resources, and 4 were very satisfied. Potential for statistically significant improvements was observed in participants' ability to make concrete plans about when, how, where, and how often to exercise. CONCLUSION: VIVA was acceptable and usable to the participants, who perceived improvements in pain and self-confidence. IMPACT: The virtual implementation of the recommendations for the nonpharmacological management of vertebral fractures showed high acceptability and usability. Future trials will implement the recommendations on a larger scale to evaluate their effectiveness.

RESUMEN

PURPOSE: To understand experiences and perceptions on non-pharmacological treatment of vertebral fractures and virtual-care from the perspective of care professionals' (HCPs). DESIGN AND SETTING: We conducted semi-structured interviews with 13 HCPs within Canada (7 F, 6 M, aged 46 ± 12 years) and performed a thematic and content analysis from a post-positivism perspective. RESULTS: Two themes were identified: acuity matters when selecting appropriate interventions; and roadblocks to receiving non-pharmacological interventions. We found that treatment options were dependent on the acuity/stability of fracture and were individualized accordingly. Pain medication was perceived as important, but non-pharmacological strategies were also considered helpful in supporting recovery. Participants discussed barriers related to the timely identification of fracture, referral to physiotherapy, and lack of knowledge among HCPs on how to manage osteoporosis and vertebral fractures. HCPs reported positive use of virtual-care, but had concerns related to patient access, cost, and comprehensive assessments. CONCLUSION: HCPs used and perceived non-pharmacological interventions as helpful and selected specific treatments based on the recency of fracture and patient symptoms. HCPs' also believed that virtual-care that included an educational component, an assessment by a physiotherapist, and an exercise group was a feasible alternative, but concerns exist and may require further evaluation.Implications for RehabilitationNon-pharmacological strategies in combination with pain medication may be a more effective strategy to support recovery than pain medication alone but should be informed by fracture acuity and patient symptoms.To improve access to physiotherapy and other non-pharmacological treatment options during the acute or chronic management of vertebral fractures, it may be worthwhile to explore the effectiveness and feasibility of virtual-care.

RESUMEN

INTRODUCTION: Muscle-strengthening and balance activities are associated with the prevention of illness and injury. Age-specific Canadian 24-Hour Movement Guidelines include recommendations for muscle/bone-strengthening and balance activities. From 2000-2014, the Canadian Community Health Survey (CCHS) included a module that assessed frequency in 22 physical activities. In 2020, a healthy living rapid response module (HLV-RR) on the CCHS asked new questions on the frequency of muscle/bonestrengthening and balance activities. The objectives of the study were to (1) estimate and characterize adherence to meeting the muscle/bone-strengthening and balance recommendations; (2) examine associations between muscle/bone-strengthening and balance activities with physical and mental health; and (3) examine trends (2000-2014) in adherence to recommendations. METHODS: Using data from the 2020 CCHS HLV-RR, we estimated age-specific prevalence of meeting recommendations. Multivariate logistic regressions examined associations with physical and mental health. Using data from the 2000-2014 CCHS, sex-specific temporal trends in recommendation adherence were explored using logistic regression. RESULTS: Youth aged 12 to 17 years (56.6%, 95% CI: 52.4-60.8) and adults aged 18 to 64 years (54.9%, 95% CI: 53.1-56.8) had significantly greater adherence to the muscle/ bone-strengthening recommendation than adults aged 65 years and older (41.7%, 95% CI: 38.9-44.5). Only 16% of older adults met the balance recommendation. Meeting the recommendations was associated with better physical and mental health. The proportion of Canadians who met the recommendations increased between 2000 and 2014. CONCLUSION: Approximately half of Canadians met their age-specific muscle/bonestrengthening recommendations. Reporting on the muscle/bone-strengthening and balance recommendations elevates their importance alongside the already recognized aerobic recommendation.

RESUMEN

The objective of this study was to explore the experiences and perspectives of individuals with chronic health conditions who had an adverse event (AE) as a result of resistance training (RT). We conducted web conference or telephone-based one-on-one semi-structured interviews with 12 participants with chronic health conditions who had an AE as a result of RT. Interview data were analyzed using the thematic framework method. Six themes were identified: (1) personal experiences with aging influence perceptions of RT; (2) physical and emotional consequences of AEs limit activities and define future RT participation; (3) injury recovery defines the severity of AE; (4) health conditions influence the perceived risks and benefits of participating in RT; (5) RT setting and trained supervision influence exercise behaviors and risk perceptions; and (6) experiencing a previous AE influences future exercise behavior. Despite participant awareness of the value and benefits of RT in both the context of aging and chronic health conditions, there is concern about experiencing exercise-related AEs. The perceived risks of RT influenced the participants' decision to engage or return to RT. Consequently, to promote RT participation, the risks, not just the benefits, should be properly reported in future studies, translated, and disseminated to the public. Novelty: -To increase the quality of published research with respect to AE reporting in RT studies. -Health care providers and people with common health conditions will be able to make evidence-based decisions as to whether the benefits of RT truly outweigh the risks.

RESUMEN

This systematic review analyzes the effects of bracing and taping after osteoporotic vertebral fractures. Spinal orthose may have positive effects on pain, but the evidence is of very low certainty. Clinical judgment is recommended when prescribing spinal orthoses. PURPOSE: To examine the effects of bracing and taping interventions on pain, physical functioning, health-related quality of life, back extensor strength, kyphosis curvature, and adverse events in individuals with vertebral fragility fractures. METHODS: Four databases were searched from inception up to January 2022. We included randomized controlled trials testing the effect of bracing or taping interventions compared with a non-intervention control in adults ≥ 45 years with vertebral fragility fractures. Narrative syntheses were presented for all the outcomes. We assessed the risk of bias using the Cochrane Risk of Bias Assessment Tool and the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation. RESULTS: Three studies were included. Soft bracing interventions exhibited inconsistent effects on pain. One study showed no difference between groups, and another study should a decrease in pain in the soft bracing group compared to the control group. Rigid bracing interventions did not have a significant change in pain between the control and intervention groups. One study demonstrated a decrease in pain at rest (VAS: - 10.8 ± 19.3) and during movement (VAS: - 20.9 ± 29.8) after a taping intervention. The other outcomes were not consistent across studies. CONCLUSIONS: Spinal orthoses may improve pain in people with vertebral fractures; however, we cannot draw definitive conclusions on the efficacy or harms of bracing or taping due to the very low certainty evidence and the small number of studies. Effects on other outcomes are uncertain.

RESUMEN

BACKGROUND: Serum alkaline phosphatase (ALP) is measured as an indicator of bone or liver disease. Bone-specific alkaline phosphatase (B-ALP) is an isoform of ALP found in the bone tissue which can predict fractures and heterotopic ossification. OBJECTIVE: The aim of this scoping review was to explore the current use of ALP and B-ALP in studies using humans or animal models of SCI, and to identify ways to advance future research using ALP and B-ALP as a bone marker after SCI. RESULTS: HUMAN STUDIES: 42 studies were included. The evidence regarding changes or differences in ALP levels in individuals with SCI compared to controls is conflicting. For example, a negative correlation between B-ALP and total femur BMD was observed in only one of three studies examining the association. B-ALP seemed to increase after administration of teriparatide, and to decrease after treatment with denosumab. The effects of exercise on ALP and B-ALP levels are heterogeneous and depend on the type of exercise performed. ANIMAL STUDIES: 11 studies were included. There is uncertainty regarding the response of ALP or B-ALP levels after SCI; levels increased after some interventions, including vibration protocols, curcumin supplementation, cycles in electromagnetic field or hyperbaric chamber. Calcitonin or bisphosphonate administration did not affect ALP levels. CONCLUSION: Researchers are encouraged to measure the bone-specific isoform of ALP rather than total ALP in future studies in humans of animal models of SCI.

RESUMEN

OBJECTIVE: To understand perceptions on rehabilitation after vertebral fracture, non-pharmacological strategies, and virtual care from the perspective of individuals living with vertebral fractures. DESIGN AND SETTING: We conducted semi-structured interviews online and performed a thematic and content analysis from a post-positivism perspective. PARTICIPANTS: Ten individuals living with osteoporotic vertebral fractures (9F, 1 M, aged 71 ± 8 years). RESULTS: Five themes emerged: pain is the defining limitation of vertebral fracture recovery; delayed diagnosis impacts recovery trajectory; living with fear; being dissatisfied with fracture management; and "getting back into the game of life" using non-pharmacological strategies. CONCLUSION: Participants reported back pain and an inability to perform activities of daily living, affecting psychological and social well-being. Physiotherapy, education, and exercise were considered helpful and important to patients; however, issues with fracture identification and referral limited the use of these options. Participants believed that virtual rehabilitation was a feasible and effective alternative to in-person care, but perceived experience with technology, cost, and individualization of programs as barriers.

RESUMEN

HYPOTHESIS: Greater peak torque and higher myotendinous density at the ankle are associated with a more plate-like architecture at the distal tibia. METHODS: In this cross-sectional study, women and men ≥ 50 years old with no metal implants, reconstructive surgery, muscular dystrophies, or tendinopathies in any leg were recruited by convenience. Isometric ankle dorsi-plantar flexion and inversion-eversion peak torques were measured using dynamometry. HR-pQCT distal tibia scans were completed. Both assessments were completed on the same day on the non-dominant leg. Integral and trabecular vBMD were derived from standard analyses, failure load (FL) was obtained from finite element analysis, plate-specific parameters were computed from individual trabecula segmentation (ITS) analysis, myotendinous density (MyD) and volume fraction (MyV/TV) were computed from soft tissue analysis. pQCT scans of the 66 % mid-leg were performed (500 µm at 15 mm/s) to obtain muscle density (MD) and muscle cross-sectional area (MCSA). STATISTICAL ANALYSIS: General linear models estimated how ankle muscle group torque and muscle size and density differentially related, both separately and together, to whole-bone properties (integral vBMD, FL) and trabecular morphometry (ITS plate parameters). Models were adjusted for age, sex, BMI, use of glucocorticoids, current osteoarthritis, and participation in moderate to vigorous recreational or sport activities. RESULTS: Among 105 participants (77 % female, mean age: 63 (10) years, BMI: 25.8 (5.4) kg/m2, 25 % with OA, 17 % fracture history, 42 % falls history), all torque measures, particularly ankle dorsiflexion and eversion, were correlates of plate-plate/rod junction density and failure load. However, muscle size and density measures were further associated with vBMD. The effect of greater ankle flexor-extensor torque on more connected bone was stronger when MyD was higher (interaction p < 0.001). CONCLUSION: Strength of muscles around the ankle are correlates of plate-like trabeculae at the distal tibia, while leaner muscle and myotendinous tissues facilitates better quality bone for stronger ankle muscle torque.

RESUMEN

Nutrition risk is linked to hospitalization, frailty, depression, and death. Loneliness during the coronavirus disease 2019 (COVID-19) pandemic may have heightened nutrition risk. We sought to determine prevalence of high nutrition risk and whether loneliness, mental health, and assistance with meal preparation/delivery were associated with risk in community-dwelling older adults (65+ years) after the first wave of COVID-19 in association analyses and when adjusting for meaningful covariates. Data were collected from 12 May 2020 to 19 August 2020. Descriptive statistics, association analyses, and linear regression analyses were conducted. For our total sample of 272 participants (78 ± 7.3 years old, 70% female), the median Seniors in the Community: Risk evaluation for Eating and Nutrition (SCREEN-8) score (nutrition risk) was 35 [1st quartile, 3rd quartile: 29, 40], and 64% were at high risk (SCREEN-8 < 38). Fifteen percent felt lonely two or more days a week. Loneliness and meal assistance were associated with high nutrition risk in association analyses. In multivariable analyses adjusting for other lifestyle factors, loneliness was negatively associated with SCREEN-8 scores (-2.92, 95% confidence interval [-5.51, -0.34]), as was smoking (-3.63, [-7.07, -0.19]). Higher SCREEN-8 scores were associated with higher education (2.71, [0.76, 4.66]), living with others (3.17, [1.35, 4.99]), higher self-reported health (0.11, [0.05, 0.16]), and resilience (1.28, [0.04, 2.52]). Loneliness, but not mental health and meal assistance, was associated with nutrition risk in older adults after the first wave of COVID-19. Future research should consider longitudinal associations among loneliness, resilience, and nutrition.

RESUMEN

If interRAI home care information were shared with primary care providers, care provision and integration could be enhanced. The objective of this study was to co-develop an interRAI-based clinical information sharing tool (i.e., the Patient Falls Risk Report) with a sample of primary care providers. This mixed-methods study employed semi-structured interviews to inform the development of the Patient Falls Risk Report and online surveys based on the System Usability Scale instrument to test its usability. Most of the interview sample (n = 9) believed that the report could support patient care by sharing relevant and actionable falls-related information. However, criticisms were identified, including insufficient detail, clarity, and support for shared care planning. After incorporating suggestions for improvement, the survey sample (n = 27) determined that the report had excellent usability with an overall usability score of 83.4 (95% CI = 78.7-88.2). By prioritizing the needs of end-users, sustainable interRAI interventions can be developed to support primary care.

RESUMEN

Objectives: To develop SCI-FX, a risk score to estimate 5-year lower extremity fragility fracture risk among patients living with chronic spinal cord injury (cSCI). Methods: Adults with traumatic cSCI (n = 90) participated in a 2-year prospective longitudinal cohort study describing bone mineral density (BMD) change and fracture incidence conducted at the Lyndhurst Centre (University Health Network), University of Waterloo, and Physical Disability Rehabilitation Institute of Québec City. Prior publication and clinical intuition were used to identify fragility fracture risk factors including prior fragility fracture, years post-injury, motor complete injury (AIS A/B), benzodiazepine use, opioid use, and parental osteoporosis. We conducted bivariate analyses to identify variables associated with fracture. Multiple logistic regressions were performed using fragility fracture incidence as the dependent variable and all variables from the univariate analyses with a highly liberal p value at 0.2. Using the odds ratios (ORs) from the multiple logistic regression model, a point system for fragility fracture risk score was developed, and the odds of fracture for each point was estimated. Results: All initial variables, with the exception of benzodiazepine exposure, were included in the final model. Conclusion: We identified a simple preliminary model for clinicians to estimate 5-year fracture risk among patients with cSCI based on their total score.

RESUMEN

Cognition, frailty, and falls have been examined independently as potential correlates of fracture risk, but not simultaneously. Our objective was to explore the association between cognition, frailty, and falls and self-reported incident fractures to determine if these factors show significant independent associations or interactions. We included participants who completed the Canadian Longitudinal Study on Aging (CLSA) 2012-2015 baseline comprehensive assessment, did not experience any self-reported fractures in the year prior to cohort recruitment, and completed the follow-up questionnaire at year 3 (n = 26,982). We compared all baseline cognitive measures available in the CLSA, the Rockwood Frailty Index (FI), and presence of self-reported falls in the past 12 months in those with versus without self-reported incident fractures in year 3 of follow-up. We used multivariable logistic regression adjusted for covariates and examined two-way interactions between cognition, frailty, and prior falls. CLSA specified analytic weights were applied. The mean ± standard error (SE) age of participants was 59.5 ± 0.1 years and 52.2% were female. A total of 715 participants (2.7%) self-reported incident fractures at 3-year follow-up. Participants who experienced incident fractures had similar baseline cognition scores (mean ± SE; Rey Auditory Verbal Learning Test [RAVLT]: Immediate recall 6.1 ± 0.1 versus 5.9 ± 0.0; standardized difference [d] 0.124); higher FI scores (mean ± SE; FI 0.134 ± 0.005 versus 0.116 ± 0.001; d 0.193), and a greater percentage had fallen in the past 12 months (weighted n [%] 518 [7.2] versus 919 [3.5]; d 0.165). FI (each increment of 0.08) was associated with a significantly increased risk of self-reported incident fractures in participants of all ages and those aged 65 years or older (adjusted odd ratio [OR] 1.24, 95% confidence limit [CL] 1.10-1.40; adjusted OR 1.44, 95% CL 1.11-1.52, respectively). The adjusted odds for self-reported incident fractures in participants of all ages was also significantly associated with falls in the past 12 months prior to baseline (adjusted OR 1.83; 95% CL 1.13-2.97), but not in those aged 65 years or older. No interactions between cognition, frailty, and prior falls were found. However, considering the relatively young age of our cohort, it may be appropriate to make strong inferences in individuals older than 65 years of age. © 2022 The Authors.
