Risk factors for osteoporotic hip fracture among community-dwelling older adults: a real-world evidence study

Abstract Background Hip fractures in the older adults lead to increased morbidity and mortality. Although a low bone mineral density is considered the leading risk factor, it is essential to recognize other factors that could affect the risk of hip fractures. This study aims to evaluate the contribution of clinical characteristics, patient-reported outcomes, and muscle and aerobic capacity for hip fractures in community-dwelling older adults. Methods This is a retrospective cohort study with real world-data from subjects ≥ 60 years old attending an outpatient clinic in Minas Gerais, Brazil, from May 1, 2019, to August 22, 2022. Data about clinical characteristics (multimorbidity, medications of long-term use, sedative and or tricyclic medications, number of falls), patient-reported outcomes (self-perception of health, self-report of difficulty walking, self-report of vision problems, and self-report of falls) and muscle and aerobic capacity (calf circumference, body mass index, and gait speed) were retrieved from an electronic health record. The association of each potential risk factor and hip fracture was investigated by a multivariable logistic regression analysis adjusted for age and sex. Results A total of 7,836 older adults were included with a median age of 80 years (IQR 72-86) and 5,702 (72.7%) were female. Hip fractures occurred in 121 (1.54%) patients. Multimorbidity was associated with an increased risk of hip fracture (OR = 1.12, 95%CI 1.06-1.18) and each episode of fall increased the chance of hip fracture by 1.7-fold (OR = 1.69, 95%CI 1.52-1.80). Patient-reported outcomes associated with increased fracture risk were regular or poor self-perception of health (OR = 1.59, 95%CI 1.06-2.37), self-report of walking difficulty (OR = 3.06, 95%CI 1.93-4.84), and self-report of falls (OR = 2.23, 95%CI 1.47-3.40). Body mass index and calf circumference were inversely associated with hip fractures (OR = 0.91, 95%CI 0.87-0.96 and OR = 0.93, 95%CI 0.88-0.97, respectively), while slow gait speed increased the chance of hip fractures by almost two-fold (OR = 1.80, 95%CI 1.22-2.66). Conclusion Our study reinforces the importance of identified risk factors for hip fracture in community-dwelling older adults beyond bone mineral density and available fracture risk assessment tools. Data obtained in primary care can help physicians, other health professionals, and public health policies to identify patients at increased risk of hip fractures.

Quality of life in older adults according to race/color: a cross-sectional study

ABSTRACT BACKGROUND: Increased longevity is accompanied by new social and health demands, such as the race/color social construct, indicating the need to identify the specific needs of older adults to maintain and improve their quality of life. OBJECTIVE: We aimed to verify the direct and indirect associations of demographic, economic, and biopsychosocial characteristics with self-assessed quality of life in older adults according to race/color. DESIGN AND SETTING: This cross-sectional study included 941 older adults living in the urban area of a health microregion in Minas Gerais, Brazil. METHODS: Older adults were divided into three groups: white (n = 585), brown (n = 238), and black (n = 102) race/color. Descriptive and trajectory analyses were performed (P < 0.05). RESULTS: Among the three groups, worse self-assessed quality of life was directly associated with lower social support scores and greater numbers of depressive symptoms. Worse self-assessed quality of life was also directly associated with a higher number of functional disabilities in basic activities of daily living and the absence of a partner among older adults of brown and black race/color. Lower monthly income and higher numbers of morbidities and compromised components of the frailty phenotype were observed among participants of white race/color, as well as lower levels of education in the brown race/color group. CONCLUSION: Factors associated with poorer self-assessed quality of life among older adults in the study community differed according to race/color.

Dietary Inflammatory and Its Association with Cognitive Frailty Among Community-Dwelling Older Adults in Klang Valley

@#Introduction: Dietary inflammation is a significant risk factor for age-related cognitive impairments among older adults. However, information related to the relationship between Empirical Dietary Inflammatory Index (eDII) score and cognitive frailty (CF) among Malaysian community-dwelling older adults is still limited. The objective of this study is to determine the association between dietary inflammatory risk and CF among community-dwelling older adults. Method: This is a cross sectional study involving community-dwelling older adults in Klang Valley. The Fried’s Criteria and Clinical Dementia Rating (CDR) were used to determine CF status. Subjects were also interviewed using the Dietary History Questionnaire (DHQ) and eDII food checklist to assess the food intake and dietary inflammatory risk. Data collected was analyzed using SPSS version 26.0. Results: A total of 158 older adults (66.7 ± 5.2 years old) residing in Klang Valley were involved. Energy and macronutrients have a weak positive association with pro-inflammatory score (p<0.05). There is no significant mean difference between CF older adults consumed a more pro-inflammatory diet (mean 2.07 ± 1.10) compared to non CF (mean 2.06 ± 1.14). However, white rice food item significantly consumed by CF people (22.4%) than non CF (8.5%) (p<0.05). Conclusion: CF older adults were more likely to consume a pro-inflammatory diet particularly from the rice food group. There is a need to further assess the risk of consuming a pro-inflammatory diet using larger sample size and appropriate biomarkers.

Mediating effects of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults / 中华行为医学与脑科学杂志

Objective:To explore the mediating role of self-perceptions of aging between frailty and cognitive function in community-dwelling older adults.Methods:From February to July 2021, a total of 528 elderly people in Xinxiang community were investigated with the frailty phenotype, the brief self-perceptions ageing questionnaire and the Mini-mental state examination(MMSE) scale.According to the MMSE total score and education level, the subjects were divided into cognitive impairment group (illiteracy≤17, primary school≤20, junior high school and above≤24, n=74) and cognitive normal group( n=454). SPSS 25.0 software was used for common method deviation test, descriptive statistics and correlation analysis, while AMOS 24.0 software was used to build structural equation model and Bootstrap method was used for intermediary effect test. Results:(1)The prevalence of cognitive impairment among the elderly in the community was 14.1%. The differences between the cognitively normal group and cognitively impaired group were statistically significant in terms of age, education, number of chronic diseases suffered and depression ( χ2=59.21, 6.53, 9.84, 25.47, all P<0.05). The differences were statistically significant in terms of frailty( χ2=75.65, P<0.001) and self-perceptions of aging ( t=77.67, P<0.001). (2)Self-perceptions of aging in the cognitively impaired group (47.39±8.66) was higher than that in the cognitively normal group (38.22±8.24) ( t=77.67, P<0.001) .Frailty score in cognitively impaired group (2.00 (1.00, 3.00)) was higher than that in the cognitively normal group (0.00 (0.00, 1.00))( Z=-8.63, P<0.001) . (3)Frailty was negatively correlated with cognitive function ( r=-0.492, P<0.01), and positively correlated with self-perceptions of aging ( r=0.540, P<0.01). Self-perceptions of aging was negatively correlated with cognitive function ( r=-0.541, P<0.01) . After controlling the influencing factors such as age, education level, chronic diseases and depression, the correlation was still significant (all P<0.01) . (4) Self-perceptions of aging played a partially mediating role in the relationship between frailty and cognitive function, the mediating effect accounted for 58.5% of the total effect. Conclusion:Frailty and self-perceptions of aging have a significant impact on the cognitive function of the elderly in the community, and self-perceptions of aging plays a partial intermediary role between the frailty and cognitive function of the elderly in the community.

Risk assessment and influencing factors of malnutrition among community-dwelling older adults in Minhang District of Shanghai / 环境与职业医学

Background The prevalence of malnutrition in older adults is high. Early use of appropriate screening scales for malnutrition risk and early intervention can effectively improve life quality of the elderly in communities. Objective To evaluate the risk of malnutrition among the community-dwelling elderly in a district of Shanghai and explore its influencing factors. Methods From October to December 2021, a total of 960 seniors aged 65 years and above in community committees (villages) of Minhang District were selected by stratified random sampling. Trained investigators conducted one-to-one interviews with included seniors using questionnaires. The questionnaires included the Geriatric Depression Scale (GDS), the Activity of Daily Living Scale (ADL), and the malnutrition risk assessment for elderly adults. Height, weight, waist circumference, and calf circumference were measured. Chi-square test and logistic regression were used to analyze potential influencing factors of malnutrition in the elderly. Results Among the 960 community-dwelling seniors of Minhang District, 13 (1.35%) were malnourished and 311 (32.40%) were at the risk of malnutrition. There were statistically significant differences in nutritional status across different categories of age, sex, monthly family income, education level, marital status, waist circumference, dental health status, activity of daily living, nutrition knowledge, suffering from chronic diseases, having > 3 chronic diseases, taking > 3 long-term prescriptions, depression symptoms, sleeping duration, daily outdoor activity time, number of daily food species (milk/soy products/fish/meat/poultry/eggs), daily intake of vegetables and fruits, daily consumption of cooking oil, frequency of physical exercise, frequency of smoking, and living alone (P < 0.05). The logistic regression analysis results showed that poor dental conditions, insufficient daily intake of milk/soy products/fish/meat/poultry/eggs (<3 kinds), insufficient daily intake of vegetables and fruits (<500 g), excessive daily consumption of cooking oil (>25 g), insufficient daily outdoor activities (<1 h·d−1), living alone, low educational level (primary school and below), suffering from chronic diseases, having > 3 chronic diseases, taking > 3 long-term prescriptions, and being single/widowed/divorced were the main risk factors for nutritional abnormalities in the elderly (P< 0.05). Conclusion The elderly in Minhang District of Shanghai have a high malnutrition risk, and their nutritional status is affected by multiple factors, including poor dental status, irrational dietary structure, insufficient time for outdoor activities, suffering from chronic diseases, having > 3 chronic diseases, taking > 3 long-term prescriptions, low educational level, living alone, and being single/widowed/divorced.

Frailty and its associates in community-dwelling older adults

SUMMARY OBJECTIVE: While the literature contains several studies on the frailty assessed during hospitalization and/or outpatient settings and nursing homes, few studies have assessed frailty in community-dwelling older adults. We investigated the prevalence of frailty and associated factors among older adults in a sample of community-dwelling older adults. METHODS: We included community-dwelling older adults >60 years living in the Fatih District of the Istanbul Province. We conducted the study between November 2014 and May 2015. We collected the data such as age, sex, number of diseases and drugs, functional status, frailty, the presence of geriatric syndromes, common diseases, and quality-of-life assessment. Frailty was evaluated by the FRAIL scale. RESULTS: A total of 204 adults (mean age: 75.4±7.3 years) were included, of whom 30.4% were robust, 42.6% were pre-frail, and 27% were frail. In multivariate analyses, associated factors of frailty were the number of drugs [odds ratio (OR)=1.240, p=0.036], the presence of cognitive impairment (OR=0.300, p=0.016), and falls (OR=1.984, p=0.048). CONCLUSION: The present study established the prevalence of frailty in a large district in the largest metropolis in the country through a valid screening method. Our results suggest that clinicians should consider frailty evaluation in patients with multiple drug usage, cognitive impairment, and falls.

Risk factors for hospitalization and death due to COVID-19 among frail community-dwelling elderly people: a retrospective cohort study

ABSTRACT BACKGROUND: Advanced age, multiple chronic diseases and frailty have been correlated with worse prognosis among coronavirus disease 2019 (COVID-19) inpatients. OBJECTIVE: To investigate potential risk factors for hospitalization and death due to COVID-19 among frail community-dwelling elderly people. DESIGN AND SETTING: Retrospective cohort study of patients followed up at a geriatric outpatient clinic in Belo Horizonte, Minas Gerais, Brazil. METHODS: The associations of demographic characteristics (age and sex) and clinical characteristics (frailty, multimorbidity, number of medications with long-term use, obesity, smoking, diabetes mellitus, pulmonary diseases, cardiovascular diseases, cerebrovascular disease, and chronic kidney disease) with the risk of hospitalization and death due to COVID-19 were explored using a multivariable logistic regression model. RESULTS: 5,295 patients (mean age 78.6 ± 9.4 years; 72.6% females) were included. After adjustments, the number of medications with long-term use was found to increase the odds of hospitalization due to COVID-19 (odds ratio, OR: 1.13; 95% confidence interval, CI: 1.06-1.22). Frailty, multimorbidity and diabetes mellitus also increased the odds of hospitalization (OR: 1.06, 95% CI: 1.02-1.09; OR: 1.17, 95% CI: 1.09-1.26; and OR: 2.27, 95% CI: 1.45-3.54, respectively) and the odds of death due to COVID-19 (OR: 1.07, 95% CI: 1.00-1.14; OR: 1.16, 95% CI: 1.03-1.32; and OR: 2.69, 95% CI: 1.79-6.14, respectively). CONCLUSIONS: Multimorbidity, frailty and diabetes mellitus increased the odds of hospitalization and death due to COVID-19 and the number of medications with long-term use increased the odds of hospitalization due to COVID-19 among frail community-dwelling elderly people.

Interactive effects of exercise and sleep on frailty severity in community-dwelling older adults: a cross-sectional study / Journal of Rural Medicine

Objectives: This study examined the effects of the interaction between exercise and sleep on frailty severity in community-dwelling older adults.Materials and Methods: This was a cross-sectional study. Data were collected in July 2019. In total, 2021 adults participated who responded to a questionnaire. Among them, 672 participants (317 men and 355 women) with valid responses were included in the analysis. Ordinal logistic regression analysis was performed to examine the association between frailty severity and the interaction between exercise and sleep. The dependent variable represents three different levels of frailty. The independent variables included basic information and interaction between exercise and sleep.Results: The results of ordinal logistic regression analysis (odds ratio [OR]) showed that the period from the start of exercise (OR=0.96), age (OR=1.00 for participants in their 60 s, OR=1.65 for those in their 70s, and OR=3.13 for those aged >80 years), poor subjective health perception (OR=2.12), poor quality of sleep (OR=1.88), stress (OR=1.62), and exercise–sleep interaction (OR=1.00 based on good-exercise–good-sleep interaction, OR=3.09 poor-exercise–good-sleep interaction, and OR=3.50 poor-exercise–poor-sleep interaction) significantly contributed to the model. The Nagelkerke coefficient of determination adjusted for degrees-of-freedom (R2), which represents the contribution rate of the regression equation, was 0.334.Conclusions: Our results suggest that a combination of good exercise and good sleep is needed to prevent frailty progression in community-dwelling older adults.

Age differences in the association of physical leisure activities with incident disability among community-dwelling older adults

BACKGROUND@#The relationship between leisure activities (LA) in old age and prevention of disability has not been fully investigated, and age and gender differences of these relationships are unknown. This study aimed to investigate whether physical and cognitive LA predicted incident disability among community-dwelling older adults by age and gender.@*METHODS@#We prospectively observed 8,275 residents aged 65 or above without disability at baseline for 3 years. Incident disability was defined as a new certification of the public long-term care insurance system. LA were classified into two types: physical LA and cognitive LA. The frequency of LA was categorized into frequent (i.e., once a week or more), moderate (i.e., monthly or yearly), and non-engagement. Covariates included age, gender, family number, education, perceived economic situation, body mass index, chronic medical conditions, alcohol consumption, smoking status, regular dental visits, depression, cognitive functioning, and social participation. Multivariable Poisson regression models were used to estimate adjusted cumulative incidence ratio (CIR) and 95% confidence interval (CI) for incident disability. We performed stratified analyses by age groups (i.e., the young-old aged 65-74 and the old-old aged 75-97) and gender (i.e., men and women).@*RESULTS@#The 3-year cumulative incidence of disability was 7.5%. After adjustment for covariates and mutual adjustment for both types of LA, a significant dose-response relationship between more frequent LA and lower risk of incident disability was found in young-old physical LA (P-trend < 0.001), in old-old cognitive LA (P-trend = 0.012), in male cognitive LA (P-trend = 0.006), and in female physical LA (P-trend = 0.030). Compared with people without LA, adjusted CIR (95% CI) of frequent LA was 0.47 (0.30-0.74) in young-old physical, 0.75 (0.58-0.96) in old-old cognitive, 0.65 (0.46-0.89) in male cognitive, and 0.70 (0.52-0.95) in female physical. Regarding the effect modification according to age and gender, only interaction between age and physical LA significantly prevented incident disability (P for interaction = 0.019).@*CONCLUSION@#We found age differences in the association of physical LA with incident disability among community-dwelling older adults. An effective measure to prevent long-term care in the community would be to recommend frequent physical LA for the young-old.

Qualitative Analysis of Opinions on the Decisions Made by Community-dwelling Elderly People regarding Their Medical Treatment and Care in the End-of-life / 日本プライマリ・ケア連合学会誌

Introduction: The objective of this study was to identify the opinions of community-dwelling elderly people on medical treatment and care choices during the end-of-life period.Methods: Self-administered questionnaires were distributed to elderly people who participated in nursing care prevention projects implemented by two municipalities in the Kanto region. Analysis of the contents included in the free-description section of the questionnaire was conducted using a qualitative coding procedure.Results: Analysis of 135 responses in the free-description section of the questionnaire led to the development of the following four final categories: 1. end-of-life is an extension of daily life; 2. end-of-life does not belong solely to oneself; 3. consideration of loved ones; and 4. the desire to determine one's own end.Conclusion: This study identified the following: community-dwelling elderly people have a tangible feeling that "end-of-life is an extension of daily life." They experience conflicting feelings of "desire to determine their own end" and "end-of-life does not belong solely to themselves," they have thoughts that include "consideration of loved ones," which take the form of concern that, based on their experience, they will be a burden on their family and those around them.

Reliability and validity of the 10-item resilience sale in Chinese community-dwelling adults / 中华行为医学与脑科学杂志

Objective:To explore the reliability and validity of the 10-item Connor-Davidson resilience scale (CD-RISC-10) in Chinese community-dwelling adults.Methods:Using multistage stratified sampling, totally 2 051 community-dwelling adults were selected and they were investigated by the 10-item Connor-Davidson resilience scale, the center for epidemiological studies depression scale (CES-D) and 10-item Kessler psychological distress scale (K10). The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to evaluate the CD-RISC-10 by SPSS 22.0 and AMOS 22.0.A parallel analysis and Velicer's minimum average partial (MAP) test were also supplemented to confirm the EFA-derived structure of the scale.Results:The Cronbach α coefficient of the CD-RISC-10 was 0.94, and the Spearman-Brown reliability was 0.89.The total correlation of the questions ranged from 0.74 to 0.81 (all P<0.01). The exploratory factor analysis retained its single dimension, which can explain 63.24% of the total variance.Confirmatory factor analysis revealed the single factor model fit data adequately ( χ2/ df=4.596, CFI=0.967, TLI=0.973, RMSEA=0.065). The resilience(27.02±13.50) was negatively correlated with depression(9.75±5.24) and psychological distress (19.23±6.37)( r=-0.32, -0.35, both P<0.01). Conclusion:The CD-RISC-10 scale has acceptable reliability and validity, with using easily and conveniently.Therefore, it is an effective tool for measuring the resilience of the community-dwelling adults.

Prevalence and Risk Factors of Sarcopenia Among Community Dwelling Older Adults in Klang Valley

@#Introduction: Sarcopenia is one of the geriatric syndromes affecting the ability of older adults to lead an independent living. However, its risk factors among Malaysian older adults are yet to be determined. This study investigated the prevalence and risk factors of sarcopenia among community-dwelling older adults in Klang Valley. Methods: This cross-sectional study involved 393 Malaysians aged 60 and above, residing in urban areas of Klang Valley recruited through convenience sampling. Socio-demographic and food intake information were obtained using validated questionnaires. Cut-off points for sarcopenia screening were obtained from the Asian Working Group of Sarcopenia(AWGS) while body impedance analysis(BIA) was employed to determine skeletal muscle index. A handgrip dynamometer was used to assess dominant handgrip strength and a 6-meter gait speed test was used to determine walking speed. Binary logistic regression analysis was used to determine the risk factors of sarcopenia. Results: Prevalence of sarcopenia was 33.6% and women(35.9%) were more affected compared to men(30.1%). The mean age of women assessed to have sarcopenia(69.1±6.5 years old) was higher compared to men(68.3±5.8 years old) (p<0.05). After adjusting for confounding factors, older adults with one year increased in age and one mg decreased in habitual dietary iron intake were estimated to be 1.08 times and 0.93 times the chances to have sarcopenia respectively. Conclusion: Approximately one-third of community-dwelling older adults in Klang Valley were assessed to have sarcopenia. Older adults aged 60 years and above and those with low dietary iron intake were at an increased risk of developing sarcopenia.

Use of sports tourism to motivate older adults to maintain increased aerobic exercise capacity and reduced arterial stiffness after supervised training: a non-randomized controlled trial / 体力科学

Habitual aerobic exercise decreases arterial stiffness, a risk factor for cardiovascular disease, and increases aerobic exercise capacity. Exercise habits can be difficult to maintain over time. We sought to determine if the prospect of participating in a sports tourism event (mountain climbing) helped older adults maintain increased aerobic exercise capacity and decreased arterial stiffness after a supervised training program. Forty community-dwelling middle-aged and older individuals were divided into training (n=20) and control (n=20) groups. The training group participated in six weeks of face-to-face exercise intervention (walking, 60%–75% of age-predicted maximal heart rate, 35–50 min/day, 1 day/week) and was additionally offered home-based walking (45 min/day, 2–4 days/week). During the same period, the control group was asked not to change their lifestyle. In the last session of the exercise program, we announced a mountain climbing event planned for six months in the future. The participants were encouraged to maintain their exercise habits leading up to the event. Arterial stiffness (brachial-ankle pulse wave velocity) and maximal oxygen uptake were measured before and after the six-week intervention and two weeks before the mountain climbing event. In the training group, arterial stiffness decreased, and maximal oxygen uptake increased after the intervention; these improvements were successfully maintained until the mountain climbing event. These parameters did not change significantly in the control group. Sports tourism may motivate older adults to maintain their exercise habits after a supervised training program.

Reliability and validity of community commitment scale in community-dwelling elderly / 中华行为医学与脑科学杂志

Objective:To explore the reliability and validity of the community commitment scale (CCS) in community-dwelling elderly people.Methods:From May to August in 2020, a total of 526 community-dwelling elderly were investigated by community commitment scale, community's self-efficacy scale for preventing social isolation (CSES). SPSS 25.0 and AMOS 22.0 softwares were used to analyze the reliability and validity.Results:The overall Cronbach's α coefficient of the community commitment scale was 0.818, and the Cronbach's α coefficients of social and belonging dimensions were 0.750 and 0.777, respectively. The Guttman split-half reliability coefficients were 0.799-0.835, and the test-retest reliability was 0.802. Each item-to-total score correlations were 0.614-0.753 (all P<0.05). The item level content validity index (I-CVI) was 0.830-1.000, the scale level content validity index (S-CVI/UA) was 0.875, and the average content validity index (S-CVI/Ave) was 0.972. Two common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 57.019%. The confirmatory factor analysis all indicators reached the adaptation standard (χ 2/ df=2.638, RMSEA=0.079, GFI=0.957, AGFI=0.918, TLI=0.936, CFI=0.956, IFI=0.957), and standardized regression coefficients were 0.63-0.80. Conclusion:The Chinese version of the community commitment scale has good reliability and validity and can be used to evaluate the social isolation of the elderly in the community.

Changes in Kihon Checklist items and new Certification of long-term care needs among Japanese community-dwelling elders / Journal of Rural Medicine

Objective: Physical frailty has been considered a risk factor for certification of long-term care needs (hereafter referred to as Certification) under Japan’s long-term care insurance (LTCI). Therefore, assessment of frailty in elders should be studied from multiple perspectives. The Kihon Checklist (KCL) is widely used to identify need for support/care among Japanese older adults. This study aims to examine the relationship between changes in KCL items and Certification among Japan’s young-old and old-old.Material and Methods: The KCL responses of 7,092 participants were assessed in April 2012 and March 2016, along with gender, age, and living environment. Deaths, Certifications, and relocations were tracked until March 2018. Changes in KCL items were categorized as bad, worse, improved, or good.Results: Between March 2016 and March 2018, about 7.3% of respondents obtained Certifications. KCL item changes increased the risk of new Certification for bad and worse groups, while improved cognitive function among the old-old possibly reduced the risk of new Certification.Conclusion: Therefore, rather than administering the KCL once, identifying KCL changes among people at risk could help prevent or delay their need for long-term care.

Association between a hilly neighborhood environment and falls among rural older adults: a cross-sectional study / Journal of Rural Medicine

Objective: Falls in older adults are a major public health issue, and it is unclear whether the neighborhood environment is associated with falls among this group. This cross-sectional study investigated whether hilly neighborhood environmental factors were associated with fall status (falls or fear of falling) in rural Japanese older adults.Materials and Methods: Data obtained from 965 participants aged 65 years and older living in Unnan City, Shimane Prefecture, Japan, in 2017 were analyzed. Fall status was assessed based on the 1-year fall incidence (yes/no) for the past year and fear of falling (yes/no) using a self-report questionnaire. For hilly neighborhood environmental factors, the mean elevation and land slope were assessed using a geographic information system. The logistic regression model examined the odds ratios (OR) and 95% confidence intervals (CIs) of fall status in quartiles for elevation and land slope, respectively, and was adjusted for confounders.Results: Falls and fear of falling were observed in 16.8% and 43.2% of participants, respectively. Falls were associated with elevation (OR 1.99, 95% CI 1.17–3.37 for Q2 vs. Q1; OR 2.02, 95% CI 1.19–3.44 for Q3 vs. Q1) and land slope (OR 1.74, 95% CI 1.04–2.93 for Q3 vs. Q1; OR 1.74, 95% CI 1.04–2.93 for Q4 vs. Q1). Fear of falling was associated with elevation (OR 1.78, 95% CI 1.19–2.65 for Q3 vs. Q1) and land slope (OR 1.51, 95% CI 1.01–2.25 for Q4 vs. Q1).Conclusion: Our study found that elevation and land slope as hilly neighborhood environment factors were positively associated with falls or fear of falling among older adults living in rural Japan. Prospective observational studies that investigate the effects of region-specific environmental factors on falls among older adults should be conducted.

Management of Malnutrition in Community-Dwelling Older Adults: The Importance of Screening and Interventions to Improve Nutritional and Functional Outcomes

@#The worldwide population is ageing rapidly, and the number of people aged ≥65 years is expected to double by 2050. Prevalence of risk of malnutrition is high among community-dwelling older adults and is associated with adverse health outcomes and higher costs of care. Anorexia of ageing is a major cause, characterized by unintentional loss of appetite and reduced oral intake. Achieving energy, protein and micronutrient requirements is important to maintaining health and functional independence. Older adults require a minimum of 1.0 to 1.2 g/kg body weight/day of protein to maintain muscle health. The only exception to this recommendation is older adults with advanced kidney disease and not on dialysis. Nutritional supplementation, in addition to diet, is often required. Several international guidelines recommend oral nutritional supplements (ONS) and dietary advice for older people with malnutrition. ONS containing β-hydroxy-β-methylbutyrate (HMB) has been shown to improve nutritional and functional outcomes in community-dwelling older adults with or at risk of malnutrition. As such, early screening for malnutrition risk in older adults is an important public health strategy. Such screening enables early identification, intervention and best clinical outcomes. Raising awareness on the importance of nutritional health in older people is key, in order to maintain physical function and independent living for as long as possible, preserve quality of life and reduce burdens of unhealthy ageing on healthcare systems.
