Evaluating an intervention to reduce fear of falling and associated activity restriction in elderly persons: design of a randomised controlled trial [ISRCTN43792817]

Background  

Fear of falling and associated activity restriction is common in older persons living in the community. Adverse consequences of fear of falling and associated activity restriction, like functional decline and falls, may have a major impact on physical, mental and social functioning of these persons. This paper presents the design of a trial evaluating a cognitive behavioural group intervention to reduce fear of falling and associated activity restriction in older persons living in the community.     

Socio-demographic, health-related and psychosocial correlates of fear of falling and avoidance of activity in community-living older persons who avoid activity due to fear of falling

Background  

Fear of falling and avoidance of activity are common in old age and are suggested to be (public) health problems of equal importance to falls. Earlier studies of correlates of fear of falling and avoidance of activity did hardly differentiate between severe and mild levels of fear of falling and avoidance of activity which may be relevant from clinical point of view. Furthermore, most studies focused only on socio-demographics and/or health-related variables and hardly incorporated an extensive range of potential correlates of fear of falling including psychosocial variables. This study analyzes the univariate and multivariate associations between five socio-demographic, seven health-related and six psychosocial variables and levels of fear of falling and avoidance of activity in older persons who avoid activity due to fear of falling.     

Nutritional status of school-age children - A scenario of urban slums in India

Objectives

This article aims at describing, in a Belgian town, the frequency of the fear of falling and of subsequent activity restriction among non-institutionalised people aged 65 years and over, and at identifying persons affected by these two issues.

Methods

Cross-sectional survey conducted in Fontaine l'Evêque (Belgium) in 2006, using a self-administered questionnaire.

Results

The participants could fill in the questionnaire on their own or with the help of a third party if needed. The latter were not taken into account in this article. Analyses covered 419 questionnaires. Fear of falling and activity restriction were reported by, respectively, 59.1% and 33.2% of participants. They were more frequent among fallers but also affected non-fallers. In logistic regression analyses: gender, the fact of living alone and the number of falls were significantly associated with fear of falling; gender, age and the number of falls were significantly associated with activity restriction.

Conclusions

Our study, despite various limitations, shows the importance of fear of falling and of subsequent activity restriction among older people, among fallers as well as among non-fallers. It also provides information, though limited, concerning persons affected by these two issues in Belgium, and in other contexts as well. Given the ageing of our populations, it is important to take these problems into account when caring for older people.     

Sustainability of a physical activity and nutrition program for seniors

Objective

This prospective cohort study aimed to determine the impact of a low cost, home-based physical activity and nutrition program for older adults at 6 months follow-up.

Design

A follow-up survey was conducted 6 months after program completion via computer-assisted telephone interviewing. The International Physical Activity Questionnaire and the Fat and Fibre Barometer were used to measure physical activity levels and dietary behaviours, respectively. Self-reported height, weight, waist and hip circumferences were obtained. Changes over three time points of data collection (baseline, post-program, follow-up) and differences between the intervention and control groups were assessed. The use of program materials was also evaluated.

Setting

Community and home-based.

Participants

Insufficiently active 60 to 70 year olds (n = 176, intervention and n = 198, control) residing in suburbs within the Perth metropolitan area.

Results

A sustained improvement was observed for the intervention group in terms of fat avoidance behaviours (p interaction =.007). Significant improvements were found for strength exercises, fibre intake, body mass index and waist-to-hip ratio at either post-program or follow-up, however the overall effect was not significant. At post-program, the intervention group increased time spent participating in moderate activity by 50 minutes (p >.05), which was followed by a significant decline at follow-up (p <.05). Among intervention group participants, males and females differed with respect to strength exercises and moderate physical activity.

Conclusion

This low-cost physical activity and nutrition intervention resulted in a sustained improvement in fat avoidance behaviours and overall short-term gains in physical activity. Future studies for older adults are recommended to investigate gender-specific behavioural barriers as well as booster interventions which focus on physical activity.     

The relationship between risk factors for falling and the quality of life in older adults

Background  

Falls are one of the major health problems that effect the quality of life among older adults. The aim of this study was to explore the relationship between quality of life (Short Form-12) and the risk factors of falls (balance, functional mobility, proprioception, muscle strength, flexibility and fear of falling) in older adults.     

Long-term follow-up of disability pensioners having musculoskeletal disorders

Background  

Previously we have conducted a randomised controlled trial (RCT) to evaluate the effect of a brief cognitive behavioural program with a vocational approach aiming to return disability pensioners with back pain to work, as compared to no intervention. One year after the intervention, 10 participants (22%) who received the program and 5 (11%) in the control group reported to have entered a return to work process. The aims of this study were to evaluate long-term effects of the intervention, and compare this effect to 2 reference populations not participating in the original trial.     

Analysis of Individual Social-ecological Mediators and Moderators and Their Ability to Explain Effect of a Randomized Neighborhood Walking Intervention

Background  

Using data from the SHAPE trial, a randomized 6-month neighborhood-based intervention designed to increase walking activity among older adults, this study identified and analyzed social-ecological factors mediating and moderating changes in walking activity.     

Improved nutrient intake in older obese adults undergoing a structured diet and exercise intentional weight loss program

Objectives  

Physicians are often reluctant to advise older obese patients to lose weight for fear of compromised nutrition and excessive loss of muscle mass and strength, all of which may lead to a loss of independence and accelerate disability. Therefore, the purpose of this study was to examine nutrient intake in older obese adults undergoing a weight loss intervention.     

Prevalence of Sarcopenia in Community-Dwelling Japanese Older Adults

Background

Sarcopenia, the age-dependent loss of skeletal muscle mass, is highly prevalent among older adults in many countries; however, the prevalence of sarcopenia in healthy Japanese community-dwelling older adults is not well characterized.

Objective

The aim of this study was to evaluate the prevalence of sarcopenia and to examine the association of sarcopenia with falls and fear of falling in community-dwelling Japanese older adults.

Design

This is a cross-sectional study.

Setting and Subjects

Healthy men (568) and women (1314) aged 65 to 89 years participated in this research.

Measurements

For all participants, 3 measurements were taken: skeletal muscle mass measurement using bioelectrical impedance, 10 m at a usual walking speed, and handgrip strength. Sarcopenia was defined as the presence of both poor muscle function (low physical performance or low muscle strength) and low muscle mass.

Results

The prevalence of sarcopenia, determined using the European Working Group on Sarcopenia in Older People–suggested algorithm, in men and women aged 65 to 89 years was 21.8% and 22.1%, respectively. The prevalence of sarcopenia increased age-dependently, especially in those older than 75 years in both genders. In the young old, the prevalence of sarcopenia was higher in women than in men; however, in those older than 85 years, the prevalence of sarcopenia was lower in women than in men (P < .05). In addition, fall incidents and fear of falling were more prevalent in sarcopenic older adults than in nonsarcopenic older adults (P < .05).

Conclusions

These results suggest that sarcopenia is highly prevalent in community-dwelling Japanese older adults and is related to falls and fear of falling.     

The reduction of disability in community-dwelling frail older people: design of a two-arm cluster randomized controlled trial

Background  

Frailty among older people is related to an increased risk of adverse health outcomes such as acute and chronic diseases, disability and mortality. Although many intervention studies for frail older people have been reported, only a few have shown positive effects regarding disability prevention. This article presents the design of a two-arm cluster randomized controlled trial on the effectiveness, cost-effectiveness and feasibility of a primary care intervention that combines the most promising elements of disability prevention in community-dwelling frail older people.     

Cognitive Frailty is Associated with Fall-Related Fracture among Older People

Objective

Cognitive frailty refers to cognitive impairment and physical frailty. Both cognitive impairment and physical frailty include risks of falling. The purpose of the study is to examine cognitive frailty and falling with/without a fracture.

Design

Cross-sectional observation study.

Setting

General communities in Japan.

Participants

Data of 10,202 older adults aged ≥ 65 years were collected.

Measurements

Physical frailty was characterized as slow walking speed and/or muscle weakness. Assessment of cognitive function included word lists memory, attention, executive function, and processing speed. Cognitive impairment refers to one or more cognitive decline indicated by at least 1.5 standard deviations below the threshold after adjusting for age and education. We operationally defined cognitive frailty as having both cognitive impairment and physical frailty. Participants were interviewed about their falling, history of fall-related fractures, and several potentially confounding factors such as demographic characteristics.

Results

Multinomial logistic regression analysis revealed that functional decline in all groups, as compared to the robust group, was significantly associated with falling without fractures, after adjusting for the covariates; cognitive impairment group (P =.017), physical frailty group (P =.002), and cognitive frailty group (P <.001). Only the cognitive frailty group had a significant association with fall-related fracture after adjusting for the covariates (OR 1.92, 95% CI: 1.20–3.08, P =.007).

Conclusion

Cognitive frailty is associated with not only falling but also fall-related fractures. Cognitive frailty may have a greater risk for fall-related fractures than cognitive impairment or physical frailty alone. Future research should examine causal the relationship between fall-related fractures and cognitive frailty.

     

Clinical and cost-effectiveness of computerised cognitive behavioural therapy for depression in primary care: Design of a randomised trial

Background  

Major depression is a common mental health problem in the general population, associated with a substantial impact on quality of life and societal costs. However, many depressed patients in primary care do not receive the care they need. Reason for this is that pharmacotherapy is only effective in severely depressed patients and psychological treatments in primary care are scarce and costly. A more feasible treatment in primary care might be computerised cognitive behavioural therapy. This can be a self-help computer program based on the principles of cognitive behavioural therapy. Although previous studies suggest that computerised cognitive behavioural therapy is effective, more research is necessary. Therefore, the objective of the current study is to evaluate the (cost-) effectiveness of online computerised cognitive behavioural therapy for depression in primary care.     

Anxiety and Response to Reading Intervention among First Grade Students

Background

For school-aged children with reading difficulties, an emerging and important area of investigation concerns determining predictors of intervention response. Previous studies have focused exclusively on cognitive and broadly defined behavioral variables. What has been missing, however, are studies examining anxiety, which is among the most commonly experienced difficulty for youth.

Objective

The present study examined anxiety among children classified as typically achieving or showing inadequate/adequate response following an intervention for reading problems.

Methods

Participants were 153 ethnically-diverse children (84 male, 69 female) evaluated in the winter and spring of their first-grade academic year. Children completed several standardized measures of reading achievement involving decoding and fluency along with a multidimensional anxiety rating scale.

Results

Repeated measures ANOVA revealed significant main effects for time and scale and significant interactions for time × scale and group × scale. Logistic regression examined whether anxiety predicted response to intervention (Y/N) at the end of the school-year.

Conclusions

Results showed overall decreases in anxiety over time, with the exception of the harm avoidance area which increased and also interacted with group (children with decoding/fluency difficulties reported less harm avoidance than typically achieving children). The harm avoidance area was most pertinent across analyses highlighting the potential importance of targeting this area; however, none of the anxiety scales predicted response group at the end of the intervention. Ongoing research is needed in this area in order to identify characteristics of inadequate responders to reading intervention programs and/or inform interventions that incorporate these socioemotional factors.     

An evaluation of the effect of an educational intervention for Australian social workers on competence in delivering brief cognitive behavioural strategies: A randomised controlled trial

Background  

Broad community access to high quality evidence-based primary mental health care is an ongoing challenge around the world. In Australia one approach has been to broaden access to care by funding psychologists and other allied health care professionals to deliver brief psychological treatments to general practitioners' patients. To date, there has been a scarcity of studies assessing the efficacy of social worker delivered psychological strategies. This study aims to build the evidence base by evaluating the impact of a brief educational intervention on social workers' competence in delivering cognitive behavioural strategies (strategies derived from cognitive behavioural therapy).     

The working mechanisms of an environmentally tailored physical activity intervention for older adults: a randomized controlled trial

Background  

The aim of this study was to explore the working mechanisms of a computer tailored physical activity intervention for older adults with environmental information compared to a basic tailored intervention without environmental information.     

The prevalence and social patterning of chronic diseases among older people in a population undergoing health transition. A 10/66 Group cross-sectional population-based survey in the Dominican Republic

Background  

Very little of the increased attention towards chronic diseases in countries with low and middle incomes has been directed towards older people, who contribute 72% of all deaths, and 14% of all Disability Adjusted Life Years linked to this group of conditions in those regions. We aimed to study the prevalence of physical, mental and cognitive diseases and impairments among older people in the Dominican Republic, their social patterning, and their relative contributions to disability.     

Effects of a physical activity and healthy eating intervention to reduce stroke risk factors in older adults

Objective

To evaluate the effects of a theory-based physical activity and healthy eating intervention aimed at reducing stroke risk factors among overweight/obese and sedentary older adults.

Methods

Between 12/2009–1/2011, participants (n = 69) were randomly assigned to an 8-week group motivational intervention or biweekly newsletters by mail. Physical activity (blinded pedometer, 7-day recall) body composition, theoretical mediator, and dietary (24-hour recall) variables were measured at pre-test and post-test. The physical activity and dietary outcomes are reported.

Results

For outcome measures, the follow-up was 90% for the intervention group (n = 29) and 91% for the control group (n = 34) for this sample. Statistically significant differences in the 7-day physical activity self-report were noted at post-test in the intervention group. The dietary measures were not statistically significant at post-test; however, the intervention group increased the quantity of vegetable servings.

Conclusion

Limited efficacy testing was supported for a combined physical activity-dietary intervention, framed by a wellness-motivation theory, and designed to reduce stroke risk factors in older adults who are sedentary and overweight/obese. Limitations were identified and recommendations for additional research provided.     

Moms in motion: a group-mediated cognitive-behavioral physical activity intervention

Background  

When examining the prevalence of physical inactivity by gender and age, women over the age of 25 are at an increased risk for sedentary behavior. Childbearing and motherhood have been explored as one possible explanation for this increased risk. Post natal exercise studies to date demonstrate promising physical and psychological outcomes, however few physical activity interventions have been theory-driven and tailored to post natal exercise initiates. The purpose of this study was to compare the effects of a group-mediated cognitive behavioral intervention based upon social-cognitive theory and group dynamics (GMCB) to a standard care postnatal exercise program (SE).
