Individual and contextual characteristics of indoor and outdoor falls in older residents of São Paulo, Brazil

Fall Risk in Adult Family Practice Non-Attenders: A Cross-Sectional Study from Slovenia

Introduction

Not much is known about the fall risk among the adult population of those who rarely visit doctors. We wanted to determine the prevalence of increased fall risk in a population of family practice non-attenders and the factors associated with it.

Methods

We included participants from family medicine practices in this cross-sectional study. To be included in the study, the participants had to be adults living in the community (home-dwelling people) who had not visited their chosen family physician in the last five years (non-attenders). The identification of the eligible persons was done through a search of electronic medical records, which yield 2,025 non-attenders. Community nurses collected data in the participants’ homes. The outcome measure was increased fall risk as assessed by the Morse fall scale: increased risk (≥25) vs. no risk.

Results

The sample consisted of 1,945 patients (96.0% response rate) with a mean age of 60.4 years (range 20.5 to 99.7 years). An increased fall risk was determined in 482 or 24.8% (95% CI: [22.9, 26.8]) of the patients. The multivariate model showed a significant association of increased fall risk with higher age (p<0.001), lower systolic blood pressure (p=0.047), poor family function (p=0.016), increased risk of malnutrition (p=0.013), higher number of chronic diseases (p=0.027), higher pain intensity (p<0.001), lower self-assessment of current health (p=0.002), and higher dependence in daily activities (p<0.001).

Conclusion

Non-attenders may have an increased risk of falling which depends on their health status and age. The inclusion of community nurses in primary healthcare teams could be of use not only to identify the non-attenders’ health needs, but also to better manage their health, especially the factors that were identified to be associated with greater fall risk.

Perceived neighbourhood environment and falls among community-dwelling adults: cross-sectional and prospective findings from the Survey of Health, Ageing and Retirement in Europe (SHARE)

We investigated the association between perceived neighbourhood characteristics and falls in community-dwelling adults, using data from Wave 5 and 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE). We included 25,467 participants aged 50 to 103 years (mean age 66.2 ± 9.6, 58.5% women), from fourteen European countries (Austria, Belgium, Czech Republic, Denmark, Estonia, France, Germany, Israel, Italy, Luxembourg, Slovenia, Spain, Sweden, Switzerland). At baseline, we recorded individual-level factors (socio-demographic, socio-economic and clinical factors), contextual-level factors (country, urban versus rural area, European region) and perceived neighbourhood characteristics (vandalism or crime, cleanliness, feeling part of neighbourhood, helpful neighbours, accessibility to services) for each participant. We recorded falls in the six months prior to the baseline and 2-year follow-up interviews. The associations between neighbourhood characteristics and falls were analysed by binary logistic regression models; odds ratios (95% confidence intervals) were calculated. Participants reporting-versus not reporting-vandalism or crime had an increased falls risk of 1.16 (1.02-1.31) at follow-up, after full adjustment; lack of cleanliness, feeling part of the neighbourhood, perceiving neighbours as helpful and difficult accessibility to services were not associated with falls. Vandalism or crime was consistently associated with increased falls risks in women, adults without functional impairment and urban areas residents. In conclusion, adverse neighbourhood environments may account for inequality in falls risk among middle-aged and older adults and could be added to fall risk stratification tools.

Perceived neighborhood and fall history among community-dwelling older adults living in a large Brazilian urban area: a multilevel approach

Few studies have examined the neighborhood features related to falls in the older population in low-and-middle-income countries, including Brazil. This study aimed to evaluate if perceived neighborhood features are related to falls among older Brazilian adults living in a large urban area. This cross-sectional study was conducted using data from 834 participants (≥60 years) from a multistage household survey in Belo Horizonte, Brazil. The association between fall history in the previous year and perceived neighborhood features (quality of services, physical and social disorder, and safety) was examined using multilevel logistic regression. The fall prevalence was 13.6%. Older adults living in neighborhoods with a higher physical disorder were more likely to report fall in the previous year, even after controlling for demographic, clinical and social variables (OR = 2.59; 95% CI = 1.14-5.87). The other neighborhood features investigated were not associated with a fall history. Our findings suggest that improving the physical environment represents an important strategy to prevent falls in the Brazilian urban older population.

Reliability of HOME FAST BRAZIL-Self-Reported Version for Community-Dwelling Older Adults

Objective: Verify the intra- and inter-rater reliability of the HOME FAST BRAZIL—Self-reported version and correlate household environmental risks with the history of falls by community-dwelling older adults.

Method: Cross sectional study with 50 community-dwelling older adults who were screened by the cut-off point of the Mini Mental State Exam and replied to the HOME FAST BRAZIL—Self-reported version using two evaluators, on three occasions. The reliability analysis was determined by the Intra-class Correlation Coefficient (ICC), considering ICC > 0.70 as adequate. To test the correlations, the Spearman test was used.

Results: The mean age of the participants was 73.2 ± 5.8 years. The inter- rater reliability of HOME FAST BRAZIL—Self-reported version was ICC 0.83 (IC95%, 0.70–0.90) and the Intra- reliability ICC 0.85 (IC95%, 0.74–0.91). A risk of falls was verified in 88% of the sample and four environmental risks presented significant correlations with the history of falls.

Conclusions: The HOME FAST BRAZIL—Self-reported version presented adequate reliability for the evaluation of household environmental risks for community-dwelling older adults. Risks such as inadequate armchairs/ sofas, the absence of anti-slip mats in the shower recess, the presence of pets and inadequate beds require attention in the evaluation of household risks, due to their correlation with the occurrence of falls.

Why a New Research Agenda on Green Spaces and Health Is Needed in Latin America: Results of a Systematic Review

(1) Background: Increasing and improving green spaces have been suggested to enhance health and well-being through different mechanisms. Latin America is experiencing fast population and urbanization growth; with rising demand for interventions to improve public health and mitigate climate change. (2) Aim: This study aimed to review the epidemiological evidence on green spaces and health outcomes in Latin America. (3) Methods: A systematic literature review of green spaces and health outcomes was carried out for studies published in Latin America before 28 September 2020. A search strategy was designed to identify studies published in Medline via PubMed and LILACS. The search strategy included terms related to green spaces combined with keywords related to health and geographical location. No time limit for the publication was chosen. The search was limited to English, Spanish, Portuguese, and French published articles and humans’ studies. (4) Findings: This systematic review found 19 epidemiological studies in Latin America related to green spaces and health outcomes. Nine studies were conducted in Brazil, six in Mexico, three in Colombia, and one in Chile. In terms of study design, 14 were cross-sectional studies, 3 ecological, and 2 cohort studies. The population included among the studies ranged from 120 persons to 103 million. The green space definition used among studies was green density or proximity (eight studies), green presence (five studies), green spaces index (four studies), and green space visit (two studies). The health outcomes included were mental health (six studies), overweight and obesity (three studies), quality of life (three studies), mortality (two studies), cardiorespiratory disease (one study), disability (one study), falls (one study), and life expectancy (one study). Eleven studies found a positive association between green spaces and health, and eight studies found no association. (5) Conclusion: This systematic review identified 19 epidemiological studies associating green spaces and health outcomes in Latin America. Most of the evidence suggests a positive association between green spaces and health in the region. However, most of the evidence was supported by cross-sectional studies. Prioritizing longitudinal studies with harmonized exposure and outcome definitions and including vulnerable and susceptible populations is needed in the region.

The HOME FAST BRAZIL self-report version: translation and transcultural adaptation into Brazilian Portuguese

OBJECTIVE

To translate and cross-culturally adapt the Home Falls and Accidents Screening Tool Self-report into Brazilian Portuguese and to correlate with the history of falls.

METHODS

The translation and transcultural adaptation process followed international parameters. The Home Falls and Accidents Screening Tool Brazil Self-report, the Mini-Mental State Examination and the history of falls were applied to 10 elderly in the pre-test and to 41 in the final. Demographic and anthropometric data were also evaluated. Spearman correlation coefficient was performed.

RESULTS

The participants considered the questionnaire easy to understand and did not report any doubts to answer the final version. There was significant correlation between: Home Falls and Accidents Screening Tool Brazil Self-report score and number of falls (ρ = 0.31, p = 0.02) and the lighting and bathroom domains with presence of falls at home (ρ = 0.44, p = 0.00 and ρ = 0.33, p = 0.02, respectively). The questionnaire indicated fall's risk scoring, 10(±2).

CONCLUSION

The Home Falls and Accidents Screening Tool Brazil Self-report showed to be comprehensible and feasible tool for self-assessment of domiciliary falls risk in Brazilian older people. The scores indicated fall's risk and were associated with the history of falls.

The Brazilian version of the Home Falls and Accidents Screening Tool (HOME FAST): translation, cross-cultural adaptation, validation and reliability

Abstract Objective: to translate and cross-culturally adapt the Home Falls and Accidents Screening Tool - HOME FAST into Brazilian Portuguese and to evaluate its construct validity and intra-and inter-rater reliability. Method: a cross-sectional study was carried out that included older people aged 60 years or older. Translation and cross-cultural adaptation were carried out in the following stages: 1. Translation, 2. Synthesis, 3. Back translation, 4. Expert panel (review and pre-final version), 5. Pre-testing, 6. Analysis by the expert panel and the final version of the instrument. The Berg Balance Scale - BBS was used to test construct validity (Spearman correlation coefficient). Additionally, intra-and inter-rater reliability analysis was conducted using the Intraclass Correlation Coefficient (ICC) and the Bland-Altman plot. Results were considered significant at p<0.05. Results: the HOME FAST-Brazil was applied to 53 older people with a mean age of 71(5) years; 79% (42) of whom were female and 21% (11) of whom were male. The translation and cross-cultural adaptation process resulted in similar versions among translations. The correlation of the total score of HOME FAST-Brazil with the BBS was ρ=-0.241, p=0.041. The reliability rate was ICC=0.99 and 0.92 (intra-and inter-rater, respectively). Conclusion: The HOME FAST-Brazil, translated and cross-culturally adapted to Brazilian Portuguese, was shown to have construct validity and excellent intra-and inter-rater reliability.

Abdominal obesity, dynapenia and dynapenic-abdominal obesity as factors associated with falls

OBJECTIVE

To investigate whether abdominal obesity, dynapenia and dynapenic-abdominal obesity are associated to the prevalence of single or recurrent falls in older adults.

METHODS

We analyzed data from 1,046 community-dwelling participants of the SABE Study (Saúde, Bem-estar e Envelhecimento/Health, Well-Being and Ageing). Participants were classified as non-dynapenic/non-abdominal obese, abdominal obese only, dynapenic only, and dynapenic-abdominal obese based on waist circumference (>102cm for men and >88cm for women) and handgrip strength (<26kg for men and <16kg for women). Multinomial logistic regression models were ran to determine associations between dynapenia/obesity/dynapenic-abdominal obesity and single/recurring falls, taking non-fallers as reference.

RESULTS

Abdominal obesity (RRR=1.90 95% CI: 1.02-3.55), dynapenia (RRR=1.80 95% CI: 1.02-3.19), and dynapenic-abdominal obesity (RRR=2.06 95% CI: 1.04-4.10) were associated with a single fall. A stronger association for dynapenic-abdominal obesity compared to the other two conditions alone was found. Dynapenia was the unique condition associated with recurrent falls (RRR=2.33, 95% CI: 1.13-4.81).

CONCLUSION

The present findings have important implications for the identification of older adults with a greater chance of falls and can help in the development of rehabilitation strategies. Therefore, abdominal obese, dynapenic, and dynapenic abdominal obese individuals should be target groups for the management of falls and their consequences.

Validation of the Fall Risk Tracking Tool (FRRISque) in elderly community dwellers

This study aimed to validate of Fall Risk Tracking Tool (FRRISque) in elderly community dwellers. A cross-sectional evaluative screening study was carried out on a sample of 854 elderly. In addition to the pilot version of FRRISque, the QuickScreen® tool was applied as a standard reference in order to validate a concurrent criterion, determining sensitivity and specificity values. Most of the elderly people were female (57.6%) with an average age of 71.87 years. The multivariate logistic regression analyses showed that only 10 FRRISque items contribute to increased elderly fall risk and they refer to the risk factors of previous falls, use of a walking aid device, polypharmacy, use of psychotropic substances, difficulty to ascend and descend a slope, difficulty to walk for a distance of 100 meters, visual and hearing impairment, low physical activity and poorly lit environment. This risk stratification model assumes sensitivity values of 91.3% and specificity values of 73.4%. The FRRISque is defined as a valid, simple, low-cost and of easy and rapid application tool that can be used by all primary health care professionals, including community health workers.

Physical Activity Level and Risk of Falling in Community-Dwelling Older Adults: Systematic Review and Meta-Analysis

This systematic review examines the association between physical activity (PA) level and risk of falling in community-dwelling older adults. A search of PubMed, Embase, CINAHL, SPORTDiscus, and Web of Science was performed in January 2017. Four prospective cohort studies investigating the incidence of falls in a period of at least 12 months and its association with the level of PA in people aged 60 years and older were reviewed and pooled for meta-analysis. The pooled risk ratio (RR) for being a recurrent faller (2,420 participants) was 39% higher among those who were in the lowest PA level (RR = 1.39; 95% confidence interval [1.17, 1.65]; I2 = 0%, p = .43; p < .0001). The association between being a faller (7,927 participants) and PA level was inconclusive. This review identified that the benefit of general PA for preventing falls is associated with the adopted PA level.

Neighborhood Environment and Falls among Community-Dwelling Older Adults

Background: Falls present a major challenge to active aging, but the relationship between neighborhood factors and falls is poorly understood. This study examined the relationship between fall events and neighborhood factors, including neighborhood social cohesion (sense of belonging, trust, friendliness, and helpfulness) and physical environment (vandalism/graffiti, rubbish, vacant/deserted houses, and perceived safety walking home at night). Methods: Data were analyzed from 9259 participants over four biennial waves (2006-2012) of the Health and Retirement Study (HRS), a nationally representative sample of adults aged 65 and older in the United States. Results: In models adjusting for demographic and health-related covariates, a one-unit increase in neighborhood social cohesion was associated with 4% lower odds of experiencing a single fall (odds ratio (OR): 0.96, 95% confidence interval (CI): 0.93-0.99) and 6% lower odds of experiencing multiple falls (OR: 0.94, 95% CI: 0.90-0.98). A one-unit increase in the physical environment scale was associated with 4% lower odds of experiencing a single fall (OR: 0.96, 95% CI: 0.93-0.99) and with 5% lower odds of experiencing multiple falls (OR: 0.95, 95% CI: 0.91-1.00) in adjusted models. Conclusions: The physical and social neighborhood environment may affect fall risk among community-dwelling older adults. Findings support the ongoing need for evidence-based fall prevention programming in community and clinical settings.
