ADVANCES IN OPHTHALMOLOGY PRACTICE AND RESEARCH 2024; 4:164-172. [PMID: 39114269 PMCID: PMC11305245 DOI: 10.1016/j.aopr.2024.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 06/20/2024] [Accepted: 06/24/2024] [Indexed: 08/10/2024]
Abstract
Background Uncorrected refractive error is a major cause of vision impairment worldwide and its increasing prevalent necessitates effective screening and management strategies. Meanwhile, deep learning, a subset of Artificial Intelligence, has significantly advanced ophthalmological diagnostics by automating tasks that required extensive clinical expertise. Although recent studies have investigated the use of deep learning models for refractive power detection through various imaging techniques, a comprehensive systematic review on this topic is has yet be done. This review aims to summarise and evaluate the performance of ocular image-based deep learning models in predicting refractive errors. Main text We search on three databases (PubMed, Scopus, Web of Science) up till June 2023, focusing on deep learning applications in detecting refractive error from ocular images. We included studies that had reported refractive error outcomes, regardless of publication years. We systematically extracted and evaluated the continuous outcomes (sphere, SE, cylinder) and categorical outcomes (myopia), ground truth measurements, ocular imaging modalities, deep learning models, and performance metrics, adhering to PRISMA guidelines. Nine studies were identified and categorised into three groups: retinal photo-based (n = 5), OCT-based (n = 1), and external ocular photo-based (n = 3).For high myopia prediction, retinal photo-based models achieved AUC between 0.91 and 0.98, sensitivity levels between 85.10% and 97.80%, and specificity levels between 76.40% and 94.50%. For continuous prediction, retinal photo-based models reported MAE ranging from 0.31D to 2.19D, and R 2 between 0.05 and 0.96. The OCT-based model achieved an AUC of 0.79-0.81, sensitivity of 82.30% and 87.20% and specificity of 61.70%-68.90%. For external ocular photo-based models, the AUC ranged from 0.91 to 0.99, sensitivity of 81.13%-84.00% and specificity of 74.00%-86.42%, MAE ranges from 0.07D to 0.18D and accuracy ranges from 81.60% to 96.70%. The reported papers collectively showed promising performances, in particular the retinal photo-based and external eye photo -based DL models. Conclusions The integration of deep learning model and ocular imaging for refractive error detection appear promising. However, their real-world clinical utility in current screening workflow have yet been evaluated and would require thoughtful consideration in design and implementation.

Abstract
OBJECTIVES To identify risk factors associated with falls in older people in rural China. METHODS A prospective cohort study was conducted across 27 villages in the rural areas of Ningxia, China. After excluding individuals younger than 60 years, a total of 758 out of the initial 822 participants were ultimately included for the collection of baseline information. Participants were followed up through telephone calls or face-to-face interviews at 3rd, 6th and 12th months following the baseline investigation. The Cox proportional hazards regression model was used to examine risk factors of falls. RESULTS A total of 758 participants underwent baseline information surveys, and all samples were included in the Cox model analysis. The study found that being woman (RR=1.879, 95% CI: 1.313 to 2.668), smoking (RR=1.972, 95% CI: 1.238 to 3.143), use of painkillers (RR=1.700, 95% CI: 1.226 to 2.356) and higher systolic blood pressure (SBP) (RR=1.081, 95% CI: 1.013 to 1.154) were associated with higher risk of falls among the elderly in rural China. After excluding those who were lost to follow-up or deceased, 738 participants completed the follow-up. There were 341 men (46.2%) and 397 women (53.8%), with an average age of 66.8±5.0 years. The fall rate in study area was 23.8% during the follow-up period. CONCLUSIONS The fall rate among the elderly in rural China was higher than other areas. Our findings revealed that being woman, smoking, medication usage, elevated SBP and people with a higher body mass index were risk factors for developing falls.

Factors Influencing the Implementation of a Fall Prevention Exercise Program for Community-Dwelling Older Adults: A Qualitative Study Guided by the PRECEDE-PROCEED Model. Clin Interv Aging 2024; 19:857-871. [PMID: 38770185 PMCID: PMC11104366 DOI: 10.2147/cia.s454043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 04/27/2024] [Indexed: 05/22/2024] Open
Abstract
Purpose Multiple falls preventions exercise programs have been rolled out globally, however, few studies have explored the factors necessary for their implementation. This study aimed to investigate the factors influencing the implementation of "Steady Feet" (SF), a 12-week community fall prevention exercise intervention, for older adults living in Singapore. Material and Methods This study utilized purposive sampling to recruit two participant groups: (i) older adults who declined or withdrew from the program and (ii) providers of the program (eg, instructors). We conducted 22 semi-structured interviews, recordings were transcribed and translated, followed by thematic analysis. Data collection and analysis were informed by the PRECEDE-PROCEED framework, focusing on predisposing, enabling, and reinforcing factors. Results Findings revealed two predisposing, four enabling, and two reinforcing themes. Predisposing themes encompassed (i) knowledge, attitudes, and practices of older adults towards exercises and falls prevention, and (ii) perceptions and attitudes of providers towards SF. Both older adults and providers identified several enabling elements in implementing SF, emphasizing the significance of (i) accessibility, availability, and affordability. Providers highlighted (ii) tools and structural support for continual engagement, (iii) minimizing variations in capabilities through a competency development program, and (iv) fostering synergistic partnerships. Positive reinforcement included (i) the role of providers in engaging and promoting participation, (ii) family support, social networks, and (iii) incentives for older adults. Conversely, both groups highlighted negative reinforcements, including (iv) communication issues and (v) repetitive exercises, while providers specifically identified (vi) labor constraints as a deterrent for implementation. Conclusion Findings indicate that effective implementation necessitates a multifaceted approach. Promoting participation involves engaging instructors, emphasizing social bonds and family involvement, offering incentives, and providing subsidized or free classes. A competency development program proved effective in reducing variations in providers' capabilities. Strengthening community partnerships, with management support, was crucial for ensuring the availability and accessibility of falls prevention programs.

Abstract
The objective of this study was to investigate factors related to recurrent falls among older adults attending primary health care, considering the biopsychosocial perspective. A representative sample of 201 older adults were interviewed in three Primary Health Care units randomly selected in a city in southeastern Brazil. Outcome included self-report of two or more falls in the past 12 months. Exposures included personal and environmental aspects, according to domains of International Classification of Functioning of the World Health Organization (ICF-WHO). Recurrent falls were reported by 24.4% of the participants. Associations with depressive symptoms (p = .003), having osteoporosis (p = .031), chronic musculoskeletal pain (p = .020), frailty (p = .013), sleep satisfaction (p < .001), and functional status (p < .001) were found. In logistic regression models, cognitive status, musculoskeletal pain, and functional status were predictors of recurrent falls; however, only sleep satisfaction remained significant in the final model. Strategies aimed at preventing recurrent falls in primary health care should consider assessments and interventions targeting sleep aspects among older adults.

Abstract
Purpose This study examined the independent associations among multisite pain, pain intensity, and the risk of falls, including a history of falls in the previous 12 months and frequent falls (≥ two falls vs one or two falls) among community-dwelling older adults. Methods A cross-sectional design from Wave 2 of the National Social Life, Health, and Aging Project was used. Data on pain intensity and location (45 sites) over the past 4 weeks were collected. Multisite pain was categorized into four groups: none, one, two, and three or more sites. The main outcomes of falls were a history of falls and frequent falls. The covariates included age, sex, race, body mass index, education, medications, and comorbidities. Results Among 3,196 participants in Wave 2, 2,697 were included because of missing key variables related to pain and fall history. The prevalence of falls and frequent falls were 30.3% (n = 817) and 12.6% (n = 339), respectively. Multisite pain at ≥ three sites (odds ratio (OR) 2.04, confidence interval (CI) [1.62, 2.57]; p < 0.001) and two sites (OR 1.72, 95% CI [1.30, 2.27]; p < 0.001) was significantly associated with an increased risk of falls. An increase in pain intensity was significantly associated with an increased risk of fall (OR 1.28, 95% CI [1.15, 1.44], p < 0.001), independent of multisite pain. Multisite pain at ≥3 sites (OR 2.19, 95% CI [1.56, 3.07], p < 0.001) and 2 sites (OR 1.54, 95% CI [1.01, 2.34], p = 0.045) was associated with an increased risk of frequent falls. An increase in pain intensity was associated with risk of frequent falls (OR 1.64, 95% CI [1.40, 1.91], p < 0.001), independent of multisite pain. Conclusion Multisite pain and pain intensity were associated with a history of falls and frequent falls among older adults, emphasizing the need for routine pain evaluation to develop fall prevention strategies in this population.

Abstract
Falls can be identified as one of the main issues in elderly population which can lead to serious consequences. Elderly population can be subdivided as community dwelling older adults and institutionalized older adults. The components of health-related physical fitness factors play an important role in the perspective of healthy ageing. The objective of the study was to determine the prevalence of falls and to compare health-related physical fitness factors between different fall categories among institutionalized older adults. This descriptive cross-sectional study comprised of one hundred and seventy-two elders above 60 years of age, living in registered elder's homes in Kandy District. The prevalence of falls was determined by the number of falls reported by the subjects. They were further categorized as non-fallers, fallers, and frequent fallers depending on the number of falls. Body Mass Index (BMI) for body composition, 2-minute walk test for cardiovascular endurance, 30 second sit to stand test for muscle strength and endurance, hand grip strength for upper body strength, chair sit and reach test for lower body flexibility and back scratch test for upper body flexibility were the measures used to assess health-related physical fitness factors. The prevalence of falls is presented as percentage and the health-related factors were compared between the three faller categories using one-way ANOVA and pairwise comparison was performed using Scheffe test. The prevalence of falls was 47.1%. There was a significant difference in BMI, cardiovascular endurance, and lower body flexibility between the three categories of fallers. Higher BMI, lower cardiovascular endurance and lower flexibility in the lower body were associated with increased prevalence of falls (p<0.05). There was no significant difference in body fat percentage, hand grip strength, lower body muscle strength and endurance and upper body flexibility (p>0.05). The findings suggest that, BMI, cardiovascular endurance, and lower body flexibility must be addressed and managed, while designing intervention programs for falls prevention among institutionalized older adults.

Abstract
Introduction The objective of this study was to assess the prevalence of falls, fear of falling (FOF), complications arising from falls, and identify possible sociodemographic and health-related factors associated with these outcomes among older adults. Methods This cross-sectional study was based on the first wave of the Ardakan Cohort Study on Aging (ACSA), which includes participants over 50 years of age residing in Ardakan, Iran. Fall history, number of fall events, FOF, hospitalizations, and fractures in the past 12 months were assessed through a face-to-face interview. Health-related factors were recorded on a self-expressed basis. Associations were assessed using multiple logistic regression. Results Among the 4,990 participants, fall history in the past 12 months was prevalent in 19.9%, with 10.1% reporting more than two fall events. Women (p < 0.001) and older participants (p< 0.001) had a higher prevalence. In females, 28.8% reported moderate to severe FOF, while 21% experienced disruptions in their daily activities as a result of this fear. The prevalence of fractures following falls was 5.1% in males and 8.6% in females. After adjusting for confounding factors, FOF (OR: 1.59, 95% CI: 1.33-1.91, p<0.001), imbalance (OR: 2.45, 95% CI: 1.68-3.58, p<0.001), urinary incontinence (OR: 1.44, 95% CI: 1.04-1.9, p=0.025), cognitive impairment (OR: 1.21, 95% CI: 1.01-1.46, p=0.049), vertigo or dizziness (OR: 1.39, 95% CI: 1.15-1.68, p<0.001), osteoporosis (OR: 1.24, 95% CI: 1.03-1.50, p=0.023), osteoarthritis (OR: 1.33, 95% CI: 1.13-1.56, p=0.001), depression (OR: 1.30, 95% CI: 1.06-1.60, p=0.010), and Central Nervous System (CNS)-affecting diseases (OR: 1.99, 95% CI: 1.33-2.97, p=0.001) were found to have positive associations with falls. Conclusion This study showed that about one-fifth of those over 50 in Iran have experienced at least one fall within a year. Self-expressed imbalance, FOF, and urinary incontinence were the most prominent risk factors. Due to resulting in hospitalization and fractures, falls also lead to fear of falling and the associated limitation of activities.

Abstract
BACKGROUND Association between baseline visual impairment (VI) bilaterality and severity, and associated causes; and incident and frequent falls at 6 years in a multiethnic Asian population aged ≥60 years. METHODS It is a population-based prospective cohort study. Visual acuity was clinically measured at both visits. Self-reported incidence and frequency of falls were defined as having no fall at baseline but having one fall and ≥2 incident falls in the 12 months prior to the follow-up visit, respectively. RESULTS Of the 1972 older participants (mean age (SD): 67.37 (5.4) years), 253 (12.8%) and 69 (3.5%) reported at least one fall and ≥2 falls, respectively, at a 6-year follow-up. After multivariable adjustments, baseline bilateral VI, but not unilateral, was associated with higher odds of any incident falls (mild bilateral VI: OR=1.79, 95% CI 1.07 to 2.98; moderate-severe VI in one eye and mild VI in the other eye: OR=1.58, 95% CI 1.01 to 2.47). However, having any form of bilateral VI (OR ranging between 2.46 and 4.32; all p<0.05) and even unilateral mild VI (OR=2.34, 95% CI 1.09 to 5.03) significantly increased the odds of incident frequent falls, compared with bilateral normal vision. VI caused by correctable (OR=2.02, 95% CI 1.19 to 3.44) and uncorrectable (OR=3.09, 95% CI 1.08 to 8.80) eye conditions were both associated with greater odds of incident frequent falls, compared with no VI. CONCLUSIONS Baseline bilateral but not unilateral VI conferred nearly two-fold higher odds of incident fall. Importantly, even mild unilateral VI conferred a substantially greater likelihood of frequent falls from correctable and uncorrectable conditions.

Neighborhood Socioeconomic Status, Green Space, and Walkability and Risk for Falls Among Postmenopausal Women: The Women's Health Initiative. Womens Health Issues 2023; 33:443-458. [PMID: 37149415 PMCID: PMC10330171 DOI: 10.1016/j.whi.2023.03.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 03/01/2023] [Accepted: 03/24/2023] [Indexed: 05/08/2023]
Abstract
PURPOSE This study estimated associations between neighborhood socioeconomic status (NSES), walkability, green space, and incident falls among postmenopausal women and evaluated modifiers of these associations, including study arm, race and ethnicity, baseline household income, baseline walking, age at enrollment, baseline low physical functioning, baseline fall history, climate region, and urban-rural residence. METHODS The Women's Health Initiative recruited a national sample of postmenopausal women (50-79 years) across 40 U.S. clinical centers and conducted yearly assessments from 1993 to 2005 (n = 161,808). Women reporting a history of hip fracture or walking limitations were excluded, yielding a final sample of 157,583 participants. Falling was reported annually. NSES (income/wealth, education, occupation), walkability (population density, diversity of land cover, nearby high-traffic roadways), and green space (exposure to vegetation) were calculated annually and categorized into tertiles (low, intermediate, high). Generalized estimating equations assessed longitudinal relationships. RESULTS NSES was associated with falling before adjustment (high vs. low, odds ratio, 1.01; 95% confidence interval, 1.00-1.01). Walkability was significantly associated with falls after adjustment (high vs. low, odds ratio, 0.99; 95% confidence interval, 0.98-0.99). Green space was not associated with falling before or after adjustment. Study arm, race and ethnicity, household income, age, low physical functioning, fall history, and climate region modified the relationship between NSES and falling. Race and ethnicity, age, fall history, and climate region modified relationships between walkability and green space and falling. CONCLUSIONS Our results did not show strong associations of NSES, walkability, or green space with falling. Future research should incorporate granular environmental measures that may directly relate to physical activity and outdoor engagement.

Wu JX, Deng FY, Lei SF. The Casual Association Inference for the Chain of Falls Risk Factors-Falls-Falls Outcomes: A Mendelian Randomization Study. Healthcare (Basel) 2023; 11:1889. [PMID: 37444723 DOI: 10.3390/healthcare11131889] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 06/20/2023] [Accepted: 06/28/2023] [Indexed: 07/15/2023] Open
Abstract
Previous associations have been observed not only between risk factors and falls but also between falls and their clinical outcomes based on some cross-sectional designs, but their causal associations were still largely unclear. We performed Mendelian randomization (MR), multivariate Mendelian randomization (MVMR), and mediation analyses to explore the effects of falls. Our study data are mainly based on White European individuals (40-69 years) downloaded from the UK Biobank. MR analyses showed that osteoporosis (p = 0.006), BMI (p = 0.003), sleeplessness (p < 0.001), rheumatoid arthritis (p = 0.001), waist circumference (p < 0.001), and hip circumference (p < 0.001) have causal effects on falls. In addition, for every one standard deviation increase in fall risk, the risk of fracture increased by 1.148 (p < 0.001), the risk of stroke increased by 2.908 (p = 0.003), and a 1.016-fold risk increase in epilepsy (p = 0.009). The MVMR found that sleeplessness is an important risk factor for falls. Finally, our mediation analyses estimated the mediation effects of falls on the hip circumference and fracture (p < 0.001), waist circumference and epilepsy (p < 0.001), and sleeplessness and fracture (p = 0.005). Our study inferred the causal effects between risk factors and falls, falls, and outcomes, and also constructed three causal chains from risk factors → falls → falls outcomes.

Reference Values, Determinants and Regression Equation for the Timed-Up and Go Test (TUG) in Healthy Asian Population Aged 21 to 85 Years. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:ijerph20095712. [PMID: 37174230 PMCID: PMC10178718 DOI: 10.3390/ijerph20095712] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/10/2023] [Accepted: 04/26/2023] [Indexed: 05/15/2023]
Abstract
The "Timed-Up-and-Go" test (TUG) is a standard assessment tool for functional mobility as it assesses several functional components, including balance, gait, and lower-extremity strength. It has good reliability and validity and is cost-effective and safe, making it an ideal screening tool for falls in various populations, such as older adults or various conditions. However, TUG interpretation relies on comparisons against local normative reference values (NRV), which few studies established for the Asian or younger population. Hence, this study aims to: (1) establish the normative reference values NRV for the population aged 21 to 85 years; (2) determine demographic and anthropometric variables that influence the TUG results; and (3) establish the regression equation of the TUG. A prospective, convenience sampling cross-sectional study recruited subjects aged 21-85 from the community to complete two TUG trials in various parts of Singapore. Variables collected include gender, age, height (meters, m), weight (kilograms, kg), and hand grip strength (HGS) (kg). The intraclass correlation coefficient (ICC) and 95% confidence interval (95% CI) determined test-retest, intra- and inter-rater reliabilities. TUG and variables were analyzed with descriptive statistics and multiple linear regression. p < 0.05 was accepted as statistical significance. Further, 838 subjects (542 females, 296 males) completed the data collection. The mean TUG time was 9.16 s (95% CI 9.01-9.3). Slower TUG was observed with advanced age and female gender. Multiple linear regression analysis demonstrated that age, height, and weight were the best variables to predict TUG scores. The regression formula presented as: TUG (second) = 9.11 + 0.063 (Age, years)-3.19 (Height, meters) + 0.026 (Weight, Kilograms) (R2 = 0.374, p < 0.001). This study provided the TUG NRV and regression formula for healthy Asian adults aged 21 to 85. The information may provide a quick reference for the physical function to interpret assessment findings and guide decision-making in various health and healthcare settings.

Abstract
OBJECTIVES Our study aimed to identify the risk factors of incident falls between men and women. DESIGN Prospective cohort study. SETTING The study recruited participants from the Central region of Singapore. Baseline and follow-up data were collected via a face-to-face survey. PARTICIPANTS Community-dwelling adults aged 40 years and above from the Population Health Index Survey. OUTCOME MEASURE Incident falls were defined as the experience of a fall between the baseline and 1-year follow-up but having no falls 1 year prior to baseline. Multiple logistic regressions were performed to determine the association of sociodemographic factors, medical history and lifestyle with incident falls. Sex subgroup analyses were conducted to examine sex-specific risk factors for incident falls. RESULTS 1056 participants were included in the analysis. At 1-year follow-up, 9.6% of the participants experienced an incident fall. Incidence of falls in women was 9.8% compared with 7.4% in men. In the multivariable analysis for the overall sample, older age (OR: 1.88, 95% CI: 1.10 to 2.86), being pre-frail (OR: 2.13, 95% CI: 1.12 to 4.00) and having depression or feeling depressed/anxious (OR: 2.35, 95% CI: 1.10 to 4.99) were associated with higher odds for incident falls. In subgroup analyses, older age was a risk factor for incident falls in men (OR: 2.68, 95% CI: 1.21 to 5.90) and pre-frail was a risk factor for incident falls in women (OR: 2.82, 95% CI: 1.28 to 6.20). There was no significant interaction effect between sex and age group (p value=0.341) and sex and frailty status (p value=0.181). CONCLUSION Older age, presence of pre-frailty and having depression or feeling depressed/anxious were associated with higher odds of incident falls. In our subgroup analyses, older age was a risk factor for incident falls in men and being pre-frail was a risk factor for incident falls in women. These findings provide useful information for community health services in designing falls prevention programmes for community-dwelling adults in a multi-ethnic Asian population.

Arch Gerontol Geriatr 2023; 104:104827. [PMID: 36191493 DOI: 10.1016/j.archger.2022.104827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 09/09/2022] [Accepted: 09/27/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND/OBJECTIVE Diabetes mellitus (DM) is associated with walking performance, but potential underlying mechanisms of this association remain unclear. The present study aims to disentangle the pathways linking DM to gait and falls through the serial mediation effect of vision and cognition among the older population. METHODS Data were taken from wave 9 (2018-2019) of the English Longitudinal Study of Aging (ELSA), including 5496 participants aged 60 years and older. DM was identified based on medical diagnosis and laboratory tests. Vision and falls were self-reported. Cognition was evaluated using questionnaire. Gait speed was measured by the "timed walking test". Serial mediation analysis was performed using Mplus 8.3. RESULTS DM was associated with impaired gait speed (c = 0.085, P < 0.05) and falls (c = 0.061, P < 0.05). The serial mediation model revealed that vision and cognition significantly mediated the association of DM with impaired gait speed, with 17.97% and 23.60% of the total effects explained by vision and cognition respectively, and 3.37% explained by the path through vision and then cognition. Similarly, vision and cognition significantly mediated the association of DM with falls, with 14.99% and 6.67% of the total effects explained by vision and cognition respectively, and 1.67% explained by the path through vision and then cognition. CONCLUSIONS These findings contribute to deeper understanding of the mechanism underlying the association of DM with walking performance. Evaluation and intervention targeted at vision and the cognition may be beneficial for improving gait or reducing falls in older adults with DM.

Abstract
The objective of this research was to investigate late-life physical functioning and lifetime history of physical activity (PA) among older adults in rural and urban Arctic communities. Data was collected in a cross-sectional, population-based study among 65 to 92-year-old community-dwelling Icelanders (N = 175, 41% ≥75-year-old, 43% women, 40% rural). Late-life physical functioning was operationalised as: basic mobility (Timed Up and Go in seconds, TUG); fall risk (TUG≥12 sec); a fall (≥1 fall/year); and recurrent falls (≥2 falls/year). PA history was based on a self-assessment. Compared to urban participants, rural participants were more likely to have fallen recently, be at fall risk, and describe more PA history. Among urban participants, no fall in the past year was independently associated with more PA in middle adulthood; and worse basic mobility and late-life fall risk were independently associated with being in the ≥75-year-old group. Among rural participants, recurrent falls were independently associated with being a man; and better basic mobility was independently associated with more PA in late adulthood. To conclude, this evidence supports an important association between better late-life physical functioning and more mid- and late-life PA and encourages further research to understand high fall risk among older men in Arctic rural areas.

Abstract
PURPOSE To determine the risk of adverse outcomes among prefrail and frail individuals with and without cognitive impairment as well as those with isolated cognitive impairment compared to robust individuals without cognitive impairment. METHODS Data from the Malaysian elders longitudinal research (MELoR) study were utilised. Baseline data were obtained from home-based computer-assisted interviews and hospital-based health-checks from 2013 to 2015. Protocol of MELoR study has been described in previous study (Lim in PLoS One 12(3):e0173466, 2017). Follow-up interviews were conducted in 2019 during which data on the adverse outcomes of falls, sarcopenia, hospitalization, and memory worsening were obtained. Sarcopenia at follow-up was determined using the strength, assistance with walking, rising from a chair, climbing stairs, and falls (SARC-F) questionnaire. RESULTS Follow-up data was available for 776 participants, mean (SD) age 68.1 (7.1) years and 57.1% women. At baseline, 37.1% were robust, 12.8% had isolated cognitive impairment, 24.1% were prefrail, 1.0% were frail, 20.2% were prefrail with cognitive impairment, and 4.8% had CF. Differences in age, ethnicity, quality of life, psychological status, function and comorbidities were observed across groups. The association between CF with hospitalisation and falls compared to robust individuals was attenuated by ethnic differences. Pre-frail individuals were at increased risk of memory worsening compared robust individuals [aOR(95%CI) = 1.69 (1.09-2.60)]. Frail [7.70 (1.55-38.20)], prefrail with cognitive impairment [3.35 (1.76-6.39)] and CF [6.15 (2.35-16.11)] were significantly more likely to be sarcopenic at 5-year follow-up compared to the robust group. CONCLUSIONS Cognitive frailty was an independently predictor of sarcopenia at 5-year follow-up. The relationship between CF with falls and hospitalization, however, appeared to be accounted for by ethnic disparities. Future studies should seek to unravel the potential genetic and lifestyle variations between ethnic groups to identify potential interventions to reduce the adverse outcomes associated with CF.

Abstract
BACKGROUND Falls and fall-related injuries in older adults are a leading cause of disability and death. Evidence has shown the benefits of exercises in improving functional outcomes and reducing fall rates among community-dwelling older adults. However, there is lack of effective community-based single exercise intervention for a broad population of older adults who are at high risk for falls. We aim to evaluate the effectiveness of Steady Feet (SF), a 6-month tailored community fall prevention exercise programme for improving functional outcomes. SF classes are facilitated by community fitness instructors and an exercise video. The main outcome is between-group changes in short physical performance battery (SPPB) scores. Secondary outcomes include balance confidence, fear of falling, quality of life, fall rates, and cost effectiveness. METHODS We present the design of a 6-month randomised controlled trial of 260 older adults (≥ 60 years old). Individuals will be randomised in a 1:1 allocation ratio to the SF group or usual care group. Participants will be assessed at baseline, 3-month, and 6-month. Data on socio-demographics, co-morbidities, balance confidence, fear of falling, quality of life, physical activity level, rate of perceived exertion, fall(s) history, healthcare utilisation and cost, and satisfaction levels will be collected. Participants will also undergo functional assessments such as SPPB. Moreover, providers' satisfaction and feedback will be obtained at 3-month. DISCUSSION An effective community fall prevention programme may lead to improved functional outcomes and reduced fall rates. Findings will also help inform the implementation and scaling of SF nation-wide. TRIAL REGISTRATION Clinicaltrials.gov registration: NCT04801316. Registered on 15th March 2021.

Abstract
Background Falls are an important cause of injury and death of older people. Hence, analyzing the multifactorial risk of falls from past cases to develop multifactorial intervention programs is clinically significant. However, due to the small sample size, there are few studies on fall risk analysis of clinical characteristics of fallers, especially among older hospitalized patients. Methods We collected data on 153 inpatients who fell (age ≥ 60 years) from the hospital nursing adverse event reporting system during hospitalization at Shandong Provincial Hospital Affiliated to Shandong First Medical University, China, from January 2018 to December 2020. Patient characteristics at the time of the fall, surrounding environment, primary nurse, and adverse fall events were assessed. The enumeration data were expressed as frequency and percentage, and the chi-squared was performed between recurrent fallers and single fallers, and non-injurious and injurious fall groups. Results Cross-sectional data showed 18.3% of the 153 participants experienced an injurious fall. Compared with single fallers, a large proportion of older recurrent fallers more often experienced preexisting conditions such as cerebrovascular disease or taking hypoglycemic drugs. They were exposed to higher risks and could experience at least 3 fall times in 3 months. Besides, the credentials of their responsible nurses were often higher. Factors that increased the risk of a fall-related injury were hypoglycemic drugs (OR 2.751; 95% CI 1.114–6.795), and nursing adverse events (OR 47.571; 95% CI 14.392–157.247). Older inpatients with bed rails (OR 0.437; 95% CI 0.190–1.005) or falling at the edge of the bed (OR 0.365; 95% CI 0.138–0.964) were less likely to be injured than those without bed rails or not falling at the edge of the bed. Fall risks were significantly correlated with more severe fall-related injuries. Older patients with moderate (OR 5.517; CI 0.687–44.306) or high risk (OR 2.196; CI 0.251–19.219) were more likely to experience fall-related injuries than those with low risk. Conclusions Older inpatient falls are an ongoing challenge in hospitals in China. Our study found that the incidence of fall-related injuries among inpatients aged ≥ 60 years remained at a minor level. However, complex patient characteristics and circumstances can contribute to fall-related injuries. This study provides new evidence on fall-related injuries of older inpatients in China. Based on the factors found in this study, regular fall-related injury epidemiological surveys that investigate the reasons associated with the injuries were crucial when considering intervention measures that could refine fall-related injuries. More prospective studies should be conducted with improved and updated multidisciplinary fall risk assessment and comprehensive geriatric assessment as part of a fall-related injury prevention protocol.

Severe low back or lower limb pain is associated with recurrent falls amongst older Australians. Eur J Pain 2022; 26:1923-1937. [PMID: 35862463 PMCID: PMC9546413 DOI: 10.1002/ejp.2013] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 06/25/2022] [Accepted: 07/16/2022] [Indexed: 11/14/2022]
Abstract
Background Few studies have explored the impact of low back or lower limb pain severity on recurrent (≥2) falls in older adults. Objectives Investigate the association between the severity of low back or lower limb pain, and ≥2 falls or falls‐related injuries. Methods Community‐dwelling Australian males and females in the ASPREE Longitudinal Study of Older Persons (ALSOP), aged ≥70 years. Self‐reported, cross‐sectional questionnaire data regarding number of falls and falls‐related injuries in the last 12 months; and sites and severity of pain experienced on most days. Adjusted relative risks (RR) were estimated from multivariable Poisson regression models, for males and females separately. Results Of 14,892 ALSOP participants, 13% (n = 1983) reported ≥2 falls (‘recurrent fallers’) in the last 12 months. Males and females who reported severe low back, or severe lower limb pain on most days were more likely to report ≥2 falls in the last 12 months compared to those with mild pain (lower back: males RR = 1.70 and females RR = 1.5, p = 0.001; lower limb: males RR = 2.0, p < 0.001 and females RR = 1.4, p = 0.003). Female recurrent fallers who reported severe low back (RR = 1.3, p = 0.029) or lower limb (RR = 1.2, p = 0.024) pain on most days were more likely to report a falls‐related injury in the last 12 months compared to females with mild pain. Conclusion Severe low back or lower limb pain was associated with an increased likelihood of recurrent falls (males/females) or falls‐related injuries (females only). Assessment of severe low back and lower limb pain should be considered as a priority when undertaking falls‐risk evaluation. Significance Severe low back pain, or severe lower limb pain is associated with an increased likelihood of recurrent falls in older males and females, and an increased likelihood of falls‐related injuries in older female recurrent fallers. Assessment and management of severe low back and lower limb pain should be prioritized when undertaking falls‐risk assessment. Future longitudinal research is required to further interrogate this relationship and its underlying mechanisms.

Abstract
BACKGROUND Recurrent falls are more likely to cause injuries and disabilities than single falls. PURPOSE This study investigated the incidence and risk factors of recurrent falls among inpatients. METHODS We analyzed inpatient fall data from the anomaly event notification database and electronic medical records of a hospital. We collected data regarding 1059 inpatients who had fallen during their hospital stay. Among these inpatients, 390 (36.83%) had fallen within the previous year. RESULTS Inpatients in the orthopedics and neurology wards were at a higher risk of recurrent falls than those in surgical wards; inpatients who were physically dependent were at a higher risk of recurrent falls than those who were physically independent; inpatients with poor vision were at a lower risk of recurrent falls than those without this issue; and inpatients who were using antidepressants were at a higher risk of recurrent falls than those who were not using antidepressants. CONCLUSION The risk of recurrent falls is highly correlated with ward type, physical independence, self-perceived good vision, and use of antidepressants.

Abstract
INTRODUCTION Older persons with diabetes are at an increased risk of falls leading to fractures, head injuries and disability. OBJECTIVE To evaluate the potential relationship between falls and diabetes in older persons and identify differences in risk factors of falls among older persons with and without diabetes using the first wave dataset of the Malaysian Elders Longitudinal Research (MELoR) study. METHODOLOGY Community dwelling adults aged ≥ 55 years were selected through stratified random sampling from three parliamentary constituencies in greater Kuala Lumpur. Baseline data was obtained through computer-assisted, home-based interviews. The presence of falls was established by enquiring about falls in the preceding 12 months. Diabetes was defined as self-reported, physician-diagnosed diabetes, diabetes medication use and an HbA1c of ≥ 6.3%. RESULTS Diabetes was present in 44.4% of the overall 1610 participants. The prevalence for fall among older diabetics was 25.6%. Recurrent falls (odds ratio (OR) 1.65; 95% confidence interval (CI) 1.06-2.57) was more common among diabetics. Following adjustment for potential confounders, osteoporosis (OR 2.58; 95% CI 1.31-5.08) and dizziness (OR 1.50; 95% CI 1.01-2.23) were independent risk factors for falls. Better instrumental activities of daily living scores were protective against falls (OR 0.75; 95% CI 0.58-0.97). CONCLUSION The presence of osteoporosis and dizziness was associated with an increased risk of falls among older diabetics. These findings will need to be confirmed in future prospective follow-up of this cohort.

Abstract
PURPOSE Vision impairment (VI) is associated with poor quality of life and increased risk of falls. Few prospective data are available on Asians. This study investigates the longitudinal impact of VI and the major eye diseases on mortality risk in Asians. DESIGN Prospective cohort study with meta-analysis. METHODS We conducted a multi-ethnic prospective study of adults (40-80 years old) in the Singapore Epidemiology of Eye Diseases Study (baseline: 2004-2011). All-cause mortality was obtained from the National Death Registry until May 2017. VI was defined by best-corrected visual acuity (BCVA) <20/40 in the better eye. Major eye diseases were assessed using standard protocols. We examined associations using multivariate-adjusted Cox proportional hazards regression models. Finally, we conducted a meta-analysis of the associations between VI and mortality. RESULTS Of 9,986 participants, 1,210 deaths occurred (12.1%) over a median follow-up of 8.8 years. Compared to participants with normal vision, persons with VI had increased risk of mortality (hazards ratio [HR]: 1.53; 95% confidence interval [CI:] 1.30-1.81) in multivariate models. In ethnicity-specific analyses, this association was significant across Chinese (HR: 1.63; 95% CI: 1.08-2.48); Malays (HR: 1.31; 95% CI: 1.06-1.62); and Indians (HR: 2.25; 95% CI: 1.61-3.15). Cataract, under-corrected refractive errors (URE), and diabetic retinopathy (DR) were significantly associated with mortality (HRs: 1.30, 1.22, and 1.54, respectively). In a meta-analysis of 12 studies including 58,034 persons, VI was associated with 30% increased risk of mortality (HR: 1.3; 95% CI: 1.2-1.5). CONCLUSIONS In this multi-ethnic Asian population, VI and preventable eye conditions (cataract, URE, and DR) were associated with mortality, emphasizing the need for early detection and intervention to prevent and treat VI and major eye diseases.

JMIR Mhealth Uhealth 2021; 9:e23663. [PMID: 34636740 PMCID: PMC8548966 DOI: 10.2196/23663] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 03/20/2021] [Accepted: 06/02/2021] [Indexed: 01/23/2023] Open
Abstract
BACKGROUND Recent falls prevention guidelines recommend early routine fall risk assessment among older persons. OBJECTIVE The purpose of this study was to develop a Falls Screening Mobile App (FallSA), determine its acceptance, concurrent validity, test-retest reliability, discriminative ability, and predictive validity as a self-screening tool to identify fall risk among Malaysian older persons. METHODS FallSA acceptance was tested among 15 participants (mean age 65.93 [SD 7.42] years); its validity and reliability among 91 participants (mean age 67.34 [SD 5.97] years); discriminative ability and predictive validity among 610 participants (mean age 71.78 [SD 4.70] years). Acceptance of FallSA was assessed using a questionnaire, and it was validated against a comprehensive fall risk assessment tool, the Physiological Profile Assessment (PPA). Participants used FallSA to test their fall risk repeatedly twice within an hour. Its discriminative ability and predictive validity were determined by comparing participant fall risk scores between fallers and nonfallers and prospectively through a 6-month follow-up, respectively. RESULTS The findings of our study showed that FallSA had a high acceptance level with 80% (12/15) of older persons agreeing on its suitability as a falls self-screening tool. Concurrent validity test demonstrated a significant moderate correlation (r=.518, P<.001) and agreement (k=.516, P<.001) with acceptable sensitivity (80.4%) and specificity (71.1%). FallSA also had good reliability (intraclass correlation .948; 95% CI .921-.966) and an internal consistency (α=.948, P<.001). FallSA score demonstrated a moderate to strong discriminative ability in classifying fallers and nonfallers. FallSA had a predictive validity of falls with positive likelihood ratio of 2.27, pooled sensitivity of 82% and specificity of 64%, and area under the curve of 0.802. CONCLUSIONS These results suggest that FallSA is a valid and reliable fall risk self-screening tool. Further studies are required to empower and engage older persons or care givers in the use of FallSA to self-screen for falls and thereafter to seek early prevention intervention.

Abstract
BACKGROUND Public health responses to Coronavirus Disease 2019 (COVID-19) including lockdowns may negatively impact physical and mental functioning in clinical populations. People living with multiple sclerosis (MS) may be more susceptible to physical function deterioration while practicing social distancing. Recent reports have suggested that about 50% of people with MS (pwMS) decreased their leisure physical activity during COVID-19, and upwards of 30% reported decreased physical fitness levels. However, the impact of social distancing on adverse health-related outcomes such as falls has not received much scrutiny. Therefore, we explored the frequency and characteristics of falls experienced by people living with and without MS during the COVID-19 pandemic. METHODS Two-hundred and thirty-nine individuals, including 106 pwMS (median age: 59 years) and 133 people living without MS (median age: 66 years) were recruited for this cross-sectional study. A snowball sampling strategy was used for online recruitment. Participants completed a customized falls questionnaire and the number of falls experienced (if any) during COVID-19 was recorded. Fall-related characteristics such as the timing, locations, activities undertaken before falling and consequences, as well as self-reported physical activity were also recorded. RESULTS Overall, participants reported 232 falls (1.67 falls/person in pwMS and 0.41 falls/person in non-MS participants). People living with MS (pwMS) had a significantly higher frequency of falls (58.5% vs 21.8%; p< 0.001) and recurrent falls (45.3% vs 9.8%; p< 0.001) compared to non-MS participants. Additionally, pwMS reported a significantly higher proportion of in-home falls (83.9% vs 54.2%; p = 0.004), as well as a higher proportion of overall injuries (44.3% vs 12.5%, p< 0.001), fractures (5.7% vs 0.8%, p = 0.048), and healthcare utilization (9.4% vs 1.6%, p = 0.007) compared to non-MS participants. A similar proportion of pwMS (49.1%) and non-MS participants (52.2%) reported lower physical activity levels during COVID-19. CONCLUSION This cross-sectional study revealed that pwMS remain at high risk of falls and fall-related outcomes during COVID-19. The high number of falls experienced by pwMS is of clinical concern considering the current strain on the healthcare system. Findings from this study highlight the importance of monitoring falls and the potential for telerehabilitation in persons with MS during COVID-19.

Strength Training to Prevent Falls in Older Adults: A Systematic Review with Meta-Analysis of Randomized Controlled Trials. J Clin Med 2021; 10:jcm10143184. [PMID: 34300350 PMCID: PMC8304136 DOI: 10.3390/jcm10143184] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 07/09/2021] [Accepted: 07/13/2021] [Indexed: 12/20/2022] Open
Abstract
We performed a systematic review with meta-analysis of randomized controlled trials (RCTs) to assess the effects of strength training (ST), as compared to alternative multimodal or unimodal exercise programs, on the number of falls in older adults (≥60 years). Ten databases were consulted (CINAHL, Cochrane Library, EBSCO, EMBASE, PEDro, PubMed, Scielo, Scopus, SPORTDiscus and Web of Science), without limitations on language or publication date. Eligibility criteria were as follows: RCTs with humans ≥60 years of age of any gender with one group performing supervised ST and a group performing another type of exercise training, reporting data pertaining falls. Certainty of evidence was assessed with Grading of Recommendations, Assessment, Development and Evaluation (GRADE). Meta-analysis used a random effects model to calculate the risk ratio (RR) for number of falls. Five RCTs with six trials were included (n = 543, 76% women). There was no difference between ST and alternative exercise interventions for falls (RR = 1.00, 95% CI 0.77–1.30, p = 0.99). The certainty of evidence was very low. No dose–response relationship could be established. In sum, ST showed comparable RR based on number of falls in older adults when compared to other multimodal or unimodal exercise modalities, but evidence is scarce and heterogeneous, and additional research is required for more robust conclusions. Registration: PROSPERO CRD42020222908.

[PMID: 33331487 PMCID: PMC7726919 DOI: 10.11606/s1518-8787.2020054002579] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Accepted: 06/05/2020] [Indexed: 12/28/2022] Open
Abstract
OBJECTIVE To estimate the prevalence of accidental falls in women and to identify possible associations of sociodemographic, clinical and lifestyle variables with falls, in 2007 and 2014. METHODS Two cross-sectional studies were performed, in 2007 and 2014, within the Projeto de Saúde de Pindamonhangaba (PROSAPIN – Pindamonhangaba Health Project), with women aged between 35 to 75 years. Probabilistic samples were selected among women living in the municipality and participating in the Health Family Strategy. Data collection included: face-to-face interview, anthropometric examination and blood test. The outcome variable “have you fallen in the last six months?” was raised during the interview. The prevalence of falls in 2007 and 2014 were estimated by score with a 95% confidence interval (95%CI). Multiple logistic regression models were constructed to identify the association of independent variables with the occurrence of falls for each year based on the odds ratio (OR). We used the Stata 14.0 software for statistical analysis. RESULTS The prevalence of accidental falls were: 17.6% (95%CI 14.9–20.5) in 2007 and 17.2% (95%CI 14.8–19.8) in 2014. In 2007, factors associated with falls were: aged 50–64 years (OR = 1.81; 95%CI 1.17–2.80), high school (OR = 1.76; 95%CI 1.06–2.93), hyperuricemia (OR = 3.74; 95%CI 2.17–6.44), depression (OR = 2.07; 95%CI 1.31–3.27), poor sleep (OR = 1.78; 95%CI 1.12–2.82) and daytime sleepiness (OR = 1.86; 95%CI 1.16–2.99). In 2014, they were: aged 50–64 years (OR = 1.64; 95%CI 1.04–2.58), hyperuricemia (OR = 1.91; 95%CI 1.07–3.43) and depression (OR = 1.56; 95%CI 1.02–2.38), plus metabolic syndrome (OR = 1.60; 95%CI 1.03–2.47) and musculoskeletal pain (OR = 1.81; 95%CI 1.03–3.18). CONCLUSIONS Falls occur significantly in women aged 50 years or over, indicating that they are not restricted to older adults and that there is a need to initiate preventive measures earlier. Both studies showed similar magnitudes of occurrence of accidental falls and reinforced their multifactorial nature. In addition, hyperuricemia may be a potential new factor associated with falls.

Abstract
We evaluated the prevalence of falls and their association with visual impairment (VI) in elderly residents in 'homes for the aged' in Hyderabad, India. Participants aged ≥ 60 years were recruited from 41 homes, and a comprehensive eye examination was conducted. Interviews were conducted to collect personal and demographic information, systemic health status, fear of falling, depression, and history of falls in the last year. VI categories included low vision (presenting visual acuity worse than 6/18 to 3/60) and blindness (presenting visual acuity worse than 3/60). The data of 1,074 participants were analysed. The mean age was 74.4 years (standard deviation:8.7 years); 63.9% were women, 19.4% had no formal education, 28.1% were diabetic and 56.9% were hypertensive. The annual prevalence of falls was 29.1% (95% CI: 26.4-32.0). Multivariable analysis showed those with VI had significantly higher odds of falls (Odds Ratio:1.47; p = 0.043). The prevalence of falls was higher among those with VI due to uncorrected refractive errors. We found a very high prevalence of falls in elderly individuals living in 'homes for the aged' in Hyderabad, India. Addressing VI can result in fewer falls and contribute to healthy aging in India.

Arch Gerontol Geriatr 2020; 91:104206. [PMID: 32763757 PMCID: PMC7854835 DOI: 10.1016/j.archger.2020.104206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES Falls are a public health concern for older adults but are also common among midlife adults. However, the consequences of falls occurring during midlife are not well understood. METHODS This investigation assessed the relationship between falls and mortality among midlife adults using survey data from the Third National Health and Nutrition Examination Survey (n = 1,295), linked to the National Death Index. The relationship between recurrent falls (≥2 falls) in the past year and 10-year death rate was assessed using survey-weighted Cox regression. RESULTS Nearly 20 % of adults who died within 10 years of their interview date were recurrent fallers at the time of interview. For women only, recurrent fallers had more than 4-fold increased hazard of death within 10 years compared to non-recurrent fallers (HR = 4.41; 95 % CI:2.24,8.68). CONCLUSIONS Findings suggest that midlife women are particularly vulnerable to adverse outcomes following recurrent falls. Fall prevention efforts should include efforts targeted at midlife women.

Wong TY, Tham YC, Sabanayagam C, Cheng CY. Patterns and Risk Factor Profiles of Visual Loss in a Multiethnic Asian Population: The Singapore Epidemiology of Eye Diseases Study. Am J Ophthalmol 2019; 206:48-73. [PMID: 31095951 DOI: 10.1016/j.ajo.2019.05.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Revised: 05/03/2019] [Accepted: 05/03/2019] [Indexed: 01/27/2023]
Abstract
PURPOSE To describe the pattern and risk factor traits associated with visual loss (defined as either visual impairment [VI] or blindness) in a multiethnic Asian cohort of Malay, Indian, and Chinese individuals living in Singapore. METHODS A total of 10 020 participants from the Singapore Epidemiology of Eye Diseases Study were examined between 2004 and 2011. All underwent standardized examinations. VI (visual acuity <20/40 to ≥20/200) and blindness (visual acuity <20/200) were defined based on the US definition, better-seeing eye. Singapore Population Census 2010 was used to calculate age-standardized prevalence. Multiple logistic regression analysis was performed to determine the independent and joint risk factors associated with visual loss. RESULTS Malay individuals had higher age-standardized prevalence of best-corrected and presenting VI (5.4% and 19.9%, respectively) than Indian (3.6% and 18.0%) and Chinese individuals (3.3% and 17.2%). Cataract was the main cause for presenting and best-corrected blindness; cataract and diabetic retinopathy were the top causes for best-corrected VI, consistently observed across the 3 ethnic groups. Older age, female sex, lower socioeconomic status, diabetes, systemic comorbidities, and cognitive impairment were independently associated with increased risk of best-corrected visual loss (all P ≤ .027). Individuals aged ≥60 years with diabetes were 12.7 times (95% confidence interval, 8.39-19.23) likely to have best-corrected visual loss, compared with younger, nondiabetic individuals. Lower income and education explained 58.1% and 23.2% of best-corrected visual loss in this population, respectively. CONCLUSION In this urban multiethnic Asian population, we identified common traits associated with visual loss across Malay, Indian, and Chinese individuals. These results will be useful for the planning and designing of eye health services and strategies for Asia's rapidly developing populations living in urban communities.
