Regional differences regarding the occurrence of falls and associated factors in two populations of Brazilian longevous people

Background

Few studies have explored regional asymmetries and their implications for health policies regarding episodes of falls among the population of ≥80 years old in continental and developing countries like Brazil with deep inequalities and sociocultural differences.

Objective

To evaluate the occurrence of falls and their association with functional capacity and nutritional status in the longest oldest-old living in two municipalities in the Northeast and Southeast of Brazil.

Methods

This is a cross-sectional study, with primary data collection in which were included in the research seniors aged 80 years or more, of both sexes, belonging to two Brazilian municipalities of discrepant socioeconomic aspects. The dependent variable was the occurrence of falls in the last year. The independent variables were grouped into demographic aspects, functional capacity and nutritional status. To identify variables that contribute to the occurrence of falls, the multiple logistic regression model, adopts a significance level of 5%.

Results

The sample was composed of 415 oldest-old adults. From the total, 32.3% reported having fallen in the last year, 24.7% in Brejo dos Santos and 37.8% in São Paulo. Among the former population, the mean value of walking speed for those who had falls was 0.27 m/s and for those who had no occurrence of falls was 0.33 m/s; and, among the seniors from São Paulo, the mean values were 0.51 m/s and 0.58 m/s, respectively. Significant correlations between walking speed and falls were verified for both populations, showing that the lower the walking speed, the higher the predisposition to falls. In the final regression model, the occurrence of falls was associated with moderate balance (OR = 5.28; CI: 1.11–25.18) among the longevous people Brejo dos Santos and with very poor functional performance (OR = 16.09; CI:1.46–177.06) among those from São Paulo.

Conclusion

The results pointed out a lower prevalence of falls in longevous people from Brejo dos Santos than in those from São Paulo and differences regarding the associated factors, showing heterogeneity between the two populations; indicating the need for public policies and effective programmes aimed at preventing falls based on the maintenance or increase of functional capacity.

Urinary symptoms in older people with low back pain: Prevalence, clinical, and functional factors associated

AIMS

To identify the prevalence, clinical and functional factors associated with urinary symptoms (US) in community-dwelling older adults with acute low back pain (LBP).

METHODS

This was a cross-sectional study of data's baseline of Back Complaints in the Elders Consortium. All elders had LPB heightened. We analyzed data on urinary symptoms, intensity of pain (Numerical Rating Scale (NRS), disability (Roland Morris [RM]), depressive symptoms (CES-D), and gait speed (m/s) in the Brazilian older adults. The sample was of 586 consecutive participants of BACE-Study. Ethical approval was obtained. In addition to the prevalence analysis, logistic regression analysis was performed.

RESULTS

The prevalence of US was 18.4% and were associated with CES-D (odds ratio [OR] = 2.84; 95% confidence interval [CI] 1.66-4.86), slower gait speed (OR = 0.33; 95% CI 0.14-0.78), and LBP-related disability (OR = 1.09; 95% CI 1.04-1.13) after adjusting for radiculophaty and other confounding factors.

CONCLUSIONS

In community-dwelling older people with LBP, US were associated with depressive symptoms, gait speed, and disability. Our findings may provide a new framework for US management with respect to clinical and functional capacity. Specific physical examinations should be encouraged to assess the with acute LBP and US. Others factors can be associated with US in elders with LBP.

FACTORS ASSOCIATED WITH LOW CONCERN ABOUT FALLING IN PHYSICALLY ACTIVE OLDER PEOPLE

ABSTRACT Introduction: Fear of falling is one of the main consequences of falls in the elderly; therefore, it is important to investigate the factors associated with the reduction of this fear. Objective: The objective of this study consisted of verifying the associated factors that best explain the low concern about falling in physically active older people. Methods: A total of 162 elderly people with a mean age of 69.95 (SD = 6.69) participated in the study. The diagnostic data sheet, the Falls Efficacy Scale-International, the Senior Fitness Test and anthropometric measurements were used to obtain data. Binary Logistic Regression was used in the data analysis to estimate the Odds Ratio (OR) and 95% confidence intervals (95% CI). The p <0.05 Omnibus Test was used to assess the quality of the adjusted model, and the Hosmer-Lemeshow test was applied to verify the explanatory power of the model. Results: In the crude analysis, normal weight elderly subjects (OR = 2.86, 95% CI = 1.32-6.20) with good levels of lower limb strength (OR = 2.64, 95% CI = 1.38-5.06), are more likely to have low fear of falling. In the adjusted analysis, the model was able to explain 75% of endpoint occurrence. Conclusion: It is concluded that among the variables analyzed, age, BMI and lower limb strength best explain the low concern about falling in the elderly. Level of Evidence III; Study of nonconsecutive patients; without consistently applied reference “gold” standard.

Prevalence of fear of falling, in a sample of elderly adults in the community

Abstract Objectives: To investigate the prevalence of fear of falling among a sample of elderly persons in the community, and to analyze its correlation with age, self-perceived health, difficulty walking, use of an assistive device for walking, history of falls, and functional capacity. Method: A cross-sectional study of 314 non-institutionalized elderly individuals, living in the city of Juiz de Fora in the state of Minas Gerais) in 2015, was carried out. A household survey was conducted and fear of falling was assessed using the Falls Efficacy Scale - International - Brazil (FES-I-BRASIL). The Spearman correlation was used to verify the correlation of the independent variables with the fear of falling. The significance level for the study was 5%. Results: The prevalence of fear of falling among the elderly was 95.2% (95% CI= 92.3; 97.3). Fear of falling was significantly correlated with all the variables analyzed: age (r= 0.199), self-perceived health (r=0.299), difficulty walking (r= -0.480), use of an assistive device for walking (r=0.337), history of falls (r= -0.177), and functional capacity (r = -0.476) . Conclusions: A high prevalence of fear of falling was observed, with a significant correlation between the outcome and the variables studied. These findings point to the need for rehabilitation, prevention, and health promotion strategies that enable healthy aging.

Melhora do equilíbrio postural em mulheres idosas com o uso de informação sensorial adicional

RESUMO O processo natural do envelhecimento humano apresenta alterações morfológicas e fisiológicas, como alterações de equilíbrio e da marcha, aumentando o risco de cair. Alguns estudos investigaram a utilização da informação sensorial na melhora do equilíbrio corporal utilizando o toque suave em uma superfície rígida e estacionária, verificando uma redução significativa da oscilação corporal. Avaliou-se os efeitos da informação sensorial adicional durante a marcha em mulheres idosas. Foram avaliadas 30 mulheres com 60 anos ou mais. A adição da informação sensorial foi feita por uma bandagem infrapatelar. As participantes realizaram os testes propostos pelo Dynamic Gait Index (DGI), pelo Timed Up and Go (TUG) e pelo Teste de Caminhada de 10 Metros (TC10m), com e sem a bandagem infrapatelar. As comparações dos dados foram realizadas com o teste t pareado e o teste de Wilcoxon, com p≤0,05. Houve diferença significativa na comparação do TUG (sem bandagem: 10,13±2,1; com bandagem: 9,71±2,1, p=0,0007) e no DGI (sem bandagem: 20,65±2,1; com bandagem: 22,1±2,1, p=0,002). Não houve diferença significativa no uso da bandagem no TC10m. Os resultados mostraram que o uso da informação sensorial adicional gerada pela bandagem infrapatelar promoveu melhora da mobilidade funcional e do desempenho físico em mulheres idosas.
