Abstract
ObjectivesHealth-related physical-fitness (HRPF) involves multi-components of physical functional tests and is reported to be associated with the risk of fall. The study sought to determine whether specific physical fitness components were stronger predictors of falls among elderly people.MethodsThis prospective cohort study involved 299 community residents age ≥60 years from Shanghai, China. The baseline data included comprehensive assessment of sociodemographic, clinical, and HRPF test. Subjects were followed for 1 year and were contacted by telephone to report falls. LASSO regression and Multivariate regression analysis were used to identify risk predictors of fall. In addition, we used receiver operating characteristic (ROC) curve analyses to determine whether the predictors have diagnostic.ResultsDuring the 1-year prospective fall assessment, 11.7% of these subjects experienced one or frequent falls. LASSO models revealed that age (=0.01) and 8-ft up-and-go test score (=0.06) were positively associated with falls, while activity-specific balance confidence (ABC; = −0.007) and 2-min step test score (= −0.005) were inversely related. The Area Under roc Curve (AUC) for a linear combination of age, ABC scale score, 2-min step test and 8-ft up-and-go test was 0.778 (95% confidence interval: 0. 700–0.857), which was superior to any of the variables taken alone.ConclusionAge, activity-specific balance confidence and fitness abnormalities were determined to contribute to the incident of falls. The value of 2-min step test score, and 8-ft up-and-go test score were the key HRPF components in predicting falls among elderly people.

Normative Static Grip Strength of Saudi Arabia's Population and Influences of Numerous Factors on Grip Strength. Healthcare (Basel) 2021; 9:healthcare9121647. [PMID: 34946373 PMCID: PMC8701140 DOI: 10.3390/healthcare9121647] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 11/22/2021] [Accepted: 11/23/2021] [Indexed: 11/17/2022] Open
Abstract
Most daily tasks require exerting static grip strength which can be challenging for the elderly as their strength diminishes with age. Moreover, normative static grip strength data are important in ergonomics and clinical settings. The goal of this study is to present the gender, age-specific, hand-specific, and body-mass-index-specific handgrip strength reference of Saudi males and females in order to describe the population's occupational demand and to compare them with the international standards. The secondary objective is to investigate the effects of gender, age group, hand area, and body mass index on the grip strength. A sample of 297 (146 male and 151 female) volunteers aged between 18 and 70 with different occupations participated in the study. Grip strength data were collected using a Jamar dynamometer with standard test position, protocol, and instructions. The mean maximum voluntary grip strength values for males were 38.71 kg and 22.01 kg, respectively. There was a curvilinear relationship of grip strength to age; significant differences between genders, hand area, and some age groups; and a correlation to hand dimensions depending on the gender.

Abstract
UNLABELLED This was the first study assessing falls prospectively in middle-aged women. The 1-year incidence was 42% for any fall, which suggest falls are a major issue in middle-aged women. Middle-aged women, particularly those sustaining a fall, could be a target group for fall-prevention strategies. PURPOSE Incidence and circumstances of falls in middle-aged people are poorly understood. This cohort study aimed to elucidate the incidence and circumstances of falls over 1 year in middle-aged women. METHODS Falls were recorded monthly for 1 year by questionnaire in 2017-2019 in a population-based sample of women aged 41-62 years. The incidence of falls and injurious falls and related circumstances were descriptively analysed. RESULTS Of 273 women, 115 sustained 209 falls. The 1-year incidence was 42% for any fall, 17% for multiple (two or more) falls, and 24% for injurious falls. The incidence was greater in older age groups for any fall (33, 45, and 44% for people aged < 50, 50-55, and > 55 years, respectively), multiple falls (7, 14, and 22%) and injurious falls (15, 20, and 28%), although only the incidence of multiple falls was significantly increased across the three age groups (P = 0.01). Most falls occurred outdoors (71%) and were attributed to tripping and slipping (60%) CONCLUSIONS: Falls are a major issue in middle-aged women, a group that has been largely ignored in the prevention of falls. Middle-aged women, in particular those sustaining a fall, could be a target group for fall-prevention strategies. Future studies are needed to identify risk factors for falling in this population so as inform the development of strategies for preventing falls in middle-aged women.

Abstract
PURPOSE To investigate the relationship between falls, physical activity, and other socio-demographic and visual factors among cataract patients in Ho Chi Minh City, Vietnam. METHODS A cross-sectional study was conducted between April and November 2018. Patients presenting to two hospitals with age-related unilateral or bilateral cataract, aged ≥50 years, literate, and scheduled for a first-eye cataract surgery were recruited. The International Physical Activity Questionnaires short form was used to measure physical activity. Visual disability score was self-reported using the Catquest-9SF. The number of falls in the last 12 months prior to data collection were self-reported. Visual acuity and contrast sensitivity were measured using standard protocols. RESULTS A total of 340 patients had complete data, the majority of whom were women (62.4%), living with a spouse (66.5%), had an education level of Grade 5 or below (68.2%), and a monthly income from medium to high (58.5%). Average age was 65.7 years. A total of 135 falls were reported in the last 12 months with 27.6% reporting ≥1 fall and 7.1% ≥2 falls. Persons with high (adjusted Prevalence Ratio (aPR) = 2.4, 95%CI = 1.2, 4.7) and low (aPR = 2.4, 95%CI = 1.2, 4.6) physical activity levels had more falls compared to those with moderate levels. Women (aPR = 1.7, 95%CI = 1.04, 2.7) and those with medium income (aPR = 2.9, 95%CI = 1.2, 6.9) were more likely to fall. Poor binocular logMAR visual acuity with habitual correction (aPR = 2.3, 95%CI = 1.1, 4.6) and poor visual disability scores (aPR = 1.4, 95%CI = 1.02, 2.0) were associated with falling. CONCLUSION Patients with a moderate level of physical activity were less likely to fall compared to those with low or high levels although this U-shape relationship needs to be further investigated in prospective interventional trials. Men and those with high monthly income, better visual acuity and visual disability score were also less likely to fall. Cataract patients might be advised to maintain a moderate level of physical activity while waiting for surgery. Strategies to prevent falls may also prioritise cataract surgery for women and those with lower income.

Abstract
BACKGROUND Physical and functional losses due to aging and diseases decrease human mobility, independence, and quality of life. This study is aimed at summarizing and quantifying these losses in order to motivate solutions to overcome them with a special focus on the possibilities by using lower limb exoskeletons. METHODS A narrative literature review was performed to determine a broad range of mobility-related physical and functional measures that are affected by aging and selected cardiovascular, respiratory, musculoskeletal, and neurological diseases. RESULTS The study identified that decreases in limb maximum muscle force and power (33% and 49%, respectively, 25-75 yrs) and in maximum oxygen consumption (40%, 20-80 yrs) occur for older adults compared to young adults. Reaction times more than double (18-90 yrs) and losses in the visual, vestibular, and somatosensory systems were reported. Additionally, we found decreases in steps per day (75%, 60-85 yrs), maximum walking speed (24% 25-75 yrs), and maximum six-minute and self-selected walking speed (38% and 21%, respectively, 20-85 yrs), while we found increases in the number of falls relative to the number of steps per day (800%), injuries due to falls (472%, 30-90 yrs) and deaths caused by fall (4000%, 65-90 yrs). Measures were identified to be worse for individuals with impaired mobility. Additional detrimental effects identified for them were the loss of upright standing and locomotion, freezing in movement, joint stress, pain, and changes in gait patterns. DISCUSSION This review shows that aging and chronic conditions result in wide-ranging losses in physical and sensory capabilities. While the impact of these losses are relatively modest for level walking, they become limiting during more demanding tasks such as walking on inclined ground, climbing stairs, or walking over longer periods, and especially when coupled with a debilitating disease. As the physical and functional parameters are closely related, we believe that lost functional capabilities can be indirectly improved by training of the physical capabilities. However, assistive devices can supplement the lost functional capabilities directly by compensating for losses with propulsion, weight support, and balance support. CONCLUSIONS Exoskeletons are a new generation of assistive devices that have the potential to provide both, training capabilities and functional compensation, to enhance human mobility.

Abstract
Background Some studies have suggested that depressive disorders may play a vital role in the incidence of hip fractures. However, nationwide data are lacking regarding the association between depressive disorders and hip fractures. Objective We aimed to explore the association between depressive disorders and new-onset hip fractures. Methods We conducted a retrospective study of 11,207 patients with depressive disorders and 11,207 control patients using Taiwan’s National Health Insurance Research Database. A Cox regression model was used to evaluate the risk of hip fractures in patients with depressive disorders. Results The incidence rate ratio of hip fractures between patients with depressive disorders and controls was 1.6 (95% confidence interval [CI] = 1.29–1.99, P < .001). After adjustment for potential confounders in multivariate analysis using the Cox regression model, patients with depressive disorders were found to have 1.34 times higher risk of hip fractures than controls (95% CI = 1.08–1.66, P = .008). Furthermore, age (hazard ratio [HR] = 7.43, 95% CI = 4.94–11.19, P < .001), hypertension (HR = 1.63, 95% CI = 1.17–2.28, P = .004), diabetes mellitus (HR = 1.47, 95% CI = 1.08–1.99, P = .014), cerebrovascular disease (HR = 1.76, 95% CI = 1.31–2.35, P < .001), living in rural areas (HR = 1.88, 95% CI = 1.30–2.70, P = .001), and low monthly income (NT$0–NT$19,000: HR = 4.08, 95% CI = 1.79–9.29, P = .001 and NT$19,100–NT$42,000: HR = 4.09, 95% CI = 1.76–9.49, P = .001) were independent risk factors for new-onset hip fractures in patients with depressive disorders. Conclusion Depressive disorders might increase the risk of new-onset hip fractures, particularly in older patients and patients with hypertension, diabetes mellitus, cerebrovascular disease, or low socioeconomic status.

The Effects of Industrial Protective Gloves and Hand Skin Temperatures on Hand Grip Strength and Discomfort Rating. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14121506. [PMID: 29207573 PMCID: PMC5750924 DOI: 10.3390/ijerph14121506] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/29/2017] [Revised: 11/27/2017] [Accepted: 12/01/2017] [Indexed: 11/16/2022]
Abstract
Daily working activities and functions require a high contribution of hand and forearm muscles in executing grip force. To study the effects of wearing different gloves on grip strength, under a variety of hand skin temperatures, an assessment of the maximum grip strength was performed with 32 healthy male workers with a mean age (standard deviation) of 30.44 (5.35) years wearing five industrial gloves at three hand skin temperatures. Their ages and anthropometric characteristics including body mass index (BMI), hand length, hand width, hand depth, hand palm, and wrist circumference were measured. The hand was exposed to different bath temperatures (5 °C, 25 °C, and 45 °C) and hand grip strength was measured using a Jamar hydraulic hand dynamometer with and without wearing the gloves (chemical protection glove, rubber insulating glove, anti-vibration impact glove, cotton yarn knitted glove, and RY-WG002 working glove). The data were analyzed using the Shapiro-Wilk test, Pearson correlation coefficient, Tukey test, and analysis of variance (ANOVA) of the within-subject design analysis. The results showed that wearing gloves significantly affected the maximum grip strength. Wearing the RY-WG002 working glove produced a greater reduction on the maximum grip when compared with the bare hand, while low temperatures (5 °C) had a significant influence on grip when compared to medium (25 °C) and high (45 °C) hand skin temperatures. In addition, participants felt more discomfort in both environmental extreme conditions. Furthermore, they reported more discomfort while wearing neoprene, rubber, and RY-WG002 working gloves.

Abstract
OBJECTIVES To explore the prevalence and predicting factors of fear of falling (FOF) among community-living older adults in Korea. METHODS Secondary data analysis of the 2011 Korean National Elderly Living Conditions and Welfare Desire Survey was used. Logistic regression analysis was conducted to examine the predictors of FOF. RESULTS In total, 75.6% of older adults with normal cognition have FOF. Factors associated with an increased risk of FOF in older adults are previous experience with falling (OR = 3.734, 95% CI = 2.996-4.655), limitations in the performance of exercise involving lower extremities (OR = 2.428, 95% CI = 2.063-2.858), being female (OR = 2.335, 95% CI = 2.023-2.694), having more than three chronic diseases (OR = 1.994, 95% CI = 1.625-2.446), limitations in instrumental activities of daily living (IADLs) (OR = 1.745, 95% CI = 1.230-2.477), limitations in the performance of exercise involving upper extremities (OR = 1.646, 95% CI = 1.357-1.997), living without a spouse (OR = 1.626, 95% CI = 1.357-1.948), having poor self-rated health (OR = 1.571, 95% CI = 1.356-1.821), limitations in muscle strength (OR = 1.455, 95% CI = 1.150-1.841), age (≥75 years) (OR = 1.320, 95% CI = 1.150-1.516), lower levels of education (0-6 years) (OR = 1.231, 95% CI = 1.075-1.409), and life satisfaction (OR = 1.104, 95% CI = 1.065-1.114). CONCLUSION A multidimensional construct of general characteristics, physical, and psychosocial variables act as risk factors for FOF. Preventive intervention should be developed to decrease the FOF among Korean older adults.

Abstract
Falls, a common cause of injury among older adults, have become increasingly prevalent. As the world's population ages, the increase in-and the prevalence of-falls among older people makes this a serious and compelling societal and healthcare issue. Physical weakness is a critical predictor in falling. While considerable research has examined this relationship, comprehensive reviews of neuropsychological predictors of falls have been lacking. In this paper, we examine and discuss current studies of the neuropsychological predictors of falls in older adults, as related to sporting and non-sporting contexts. By integrating the existing evidence, we propose that brain aging is an important precursor of the increased risk of falls in older adults. Brain aging disrupts the neural integrity of motor outputs and reduces neuropsychological abilities. Older adults may shift from unconscious movement control to more conscious or attentive motor control. Increased understanding of the causes of falls will afford opportunities to reduce their incidence, reduce consequent injuries, improve overall well-being and quality of life, and possibly to prolong life.

Abstract
Objectives To evaluate the risk of fractures related with zolpidem in elderly insomnia patients. Methods Health claims data on the entire South Korean elderly population from January 2005 to June 2006 were extracted from the Health Insurance Review and Assessment Service database. We applied a case-crossover design. Cases were defined as insomnia patients who had a fracture diagnosis. We set the hazard period of 1 day length prior to the fracture date and four control periods of the same length at 5, 10, 15, and 20 weeks prior to the fracture date. Time independent confounding factors such as age, gender, lifestyle, cognitive function level, mobility, socioeconomic status, residential environment, and comorbidity could be controlled using the casecrossover design. Time dependent confounding factors, especially co-medication of patients during the study period, were adjusted by conditional logistic regression analysis. The odds ratios and their 95% confidence intervals (CIs) were estimated for the risk of fracture related to zolpidem. Results One thousand five hundred and eight cases of fracture were detected in insomnia patients during the study period. In our data, the use of zolpidem increased the risk of fracture significantly (adjusted odds ratio [aOR], 1.72; 95% CI, 1.37 to 2.16). However, the association between benzodiazepine hypnotics and the risk of fracture was not statistically significant (aOR, 1.00; 95% CI, 0.83 to 1.21). Likewise, the results were not statistically significant in stratified analysis with each benzodiazepine generic subgroup. Conclusions Zolpidem could increase the risk of fracture in elderly insomnia patients. Therefore zolpidem should be prescribed carefully and the elderly should be provided with sufficient patient education.

Abstract
UNLABELLED The aim of this study was to examine the prospective association between symptoms of anxiety and depression and risk of fracture in older people. Results showed that men, but not women, with probable anxiety at baseline had an increased risk of fracture. INTRODUCTION The use of psychotropic drugs has been linked with an increased risk of fracture in older people, but there are indications that the conditions for which these drugs were prescribed may themselves influence fracture risk. The aim of this study was to investigate the relation between symptoms of anxiety and depression and risk of fracture in older people. The study design is a prospective cohort study. METHODS One thousand eighty-seven men and 1,050 women aged 59-73 years completed the Hospital Anxiety and Depression Scale (HADS). Data on incident fracture during an average follow-up period of 5.6 years were collected through interview and a postal questionnaire. RESULTS Compared to men with no or few symptoms of anxiety (score ≤7 on the HADS anxiety subscale), men with probable anxiety (score ≥11) had an increased risk of fracture: After adjustment for age and potential confounding factors, the odds ratio (OR) (95 % confidence interval) was 4.03 (1.55, 10.5). There were no associations between levels of anxiety and fracture risk in women. Few men or women had probable depression at baseline (score ≥11 on the HADS depression subscale). Amongst men with possible depression (score 8-10), there was an increased risk of fracture that was of borderline significance: multivariate-adjusted OR 3.57 (0.99, 12.9). There was no association between possible depression and fracture risk in women. CONCLUSIONS High levels of anxiety in older men may increase their risk of fracture. Future research needs to replicate this finding in other populations and investigate the underlying mechanisms.

Abstract
AIM To investigate the relationship between depression and fall risk in the elderly. METHODS Residents of a village in Kumamoto Prefecture, Japan (563 people), aged ≥65 years were given a self-administered questionnaire survey between June and July 2010. To evaluate depression status and fall risk, the Geriatric Depression Scale--Short Form and the Simple Screening Test for Risk of Falls were administered. Adjustment factors assessed were age, sex, medical history for diseases associated with falls, usage of hypnotics, and cognitive dysfunction. We examined the relationship between depression and fall risk using multiple logistic regression analysis. Given that some degree of correlation was expected among adjustment factors in the model, we constructed a model that introduced the adjustment factors stepwise to confirm the robustness of the model and any effect of multicollinearity. RESULTS Overall (n=395), after excluding data from participants with significant cognitive disturbance or severe physical problems from among valid responders, a significant relationship was found between depression and fall risk in all models. The odds ratio was 2.28 (95% confidence interval: 1.31-3.96) in the final model, controlling for all adjustment factors. CONCLUSION Our findings suggest a significant relationship between depression and fall risk in the elderly. This relationship implies that the improvement of depression could be an effective measure to decrease fall risk in the elderly.
