Exercise for preventing falls in older people living in the community: an abridged Cochrane systematic review
ObjectivesTo assess the effects of exercise interventions for preventing falls in older people living in the community.Selection criteriaWe included randomised controlled trials evaluating the effects of any form of exercise as a single intervention on falls in people aged 60+years living in the community.ResultsExercise reduces the rate of falls by 23% (rate ratio (RaR) 0.77, 95% CI 0.71 to 0.83; 12 981 participants, 59 studies; high-certainty evidence). Subgroup analyses showed no evidence of a difference in effect on falls on the basis of risk of falling as a trial inclusion criterion, participant age 75 years+ or group versus individual exercise but revealed a larger effect of exercise in trials where interventions were delivered by a health professional (usually a physiotherapist). Different forms of exercise had different impacts on falls. Compared with control, balance and functional exercises reduce the rate of falls by 24% (RaR 0.76, 95% CI 0.70 to 0.81; 7920 participants, 39 studies; high-certainty evidence). Multiple types of exercise (commonly balance and functional exercises plus resistance exercises) probably reduce the rate of falls by 34% (RaR 0.66, 95% CI 0.50 to 0.88; 1374 participants, 11 studies; moderate-certainty evidence). Tai Chi may reduce the rate of falls by 19% (RaR 0.81, 95% CI 0.67 to 0.99; 2655 participants, 7 studies; low-certainty evidence). We are uncertain of the effects of programmes that primarily involve resistance training, dance or walking.Conclusions and implicationsGiven the certainty of evidence, effective programmes should now be implemented.
Designing physical activity interventions for women aged 50+: a qualitative study of participant perspectives
Background The Active Women over 50 trial tested a scalable program for increasing physical activity among women aged 50+. The program included information, activity tracker and email support. This study sought to describe the participant perspectives of the Active Women over 50 program and considerations for designing physical activity interventions for this demographic. Methods Women who completed the Active Women over 50 trial were purposively recruited for maximum variation in age, employment, carer responsibility, medical conditions and physical activity. Individual semi-structured interviews explored their perspectives on physical activity, Active Women over 50 program components and suggestions for future iterations. Data were thematically analysed. Results Participants’ capacity to be physically active was shaped by an interplay of factors. Our analysis generated four main themes relating to physical activity in general and to the program: Age and gender matters, Physical activity is social, Strategising for physical activity and the Self-responsibility discourse. At this midlife stage, physical activity participation was challenged by personal, life-stage and cultural factors, alongside a tension of the self-responsibility discourse which also impacted the program experience. Social factors and finding a suitable strategy for motivation were deemed integral aspects of being active. Future programs could consider facilitation of social networks and accountability, life-stage health information and positive framing to support self-responsibility. Conclusion A range of strategies is key to supporting women over 50 to be more physically active due to the variety of circumstances and levels of agency experienced. We offer suggestions that do not need to be resource intensive but could be incorporated into a scaled program.
What do older women want from a physical activity program? Stakeholder consultation to optimise design and recruitment for the Active Women over 50 trial
Background Effective recruitment and retention of participants are prerequisites for high quality physical activity intervention programs and evaluation trials, but this is underreported in the literature making it difficult to identify the most promising strategies. Incorporating stakeholder feedback in the design of program components and recruitment materials can optimise recruitment reach and the engagement of participants throughout programs and trials. Methods The Active Women over 50 randomised controlled trial is testing a program designed to support women aged 50 + to be more physically active. To optimise program design and recruitment flyers, we conducted one focus group and 17 interviews with diverse purposively sampled women aged 50 + living in New South Wales, Australia. Women were asked to review recruitment flyers and the four proposed program components: (1) health coaching, (2) dedicated website with resources, (3) private Facebook group and (4) motivational email and SMS messages. Data analysis incorporated framework methods, deductive analysis using the Adapted Mobile App Rating Scale for evaluating websites and abductive analysis to critique the underlying program theory. Results Five themes were identified in relation to recruitment: I want to see (women like) myself, Keep it real, Readability is for everyone, Why should I do it? and Find us where we live. The four program components were strongly supported as a package, but were valued differently for their relative importance. Results were used to refine the health coaching scheduling; website appearance and content; promotion and moderation of the Facebook group; and the structure, appearance and content of messages. Not all suggestions were actionable due to technological and time constraints, and the desire to keep program costs low enough for delivery at scale during the study and beyond. The program theory was expanded to encompass two emergent concepts. Conclusions This consultation resulted in substantial refinements to recruitment flyers and strategies, and all four program components. We anticipate that these refinements will increase the reach and appeal of the trial and optimise future scale-up. Consultation feedback, while specific to this program, may have wider transferability for recruitment and the design of programs with similar components targeting women aged 50+.
Using self-determination theory to understand and improve recruitment for the Coaching for Healthy Ageing (CHAnGE) trial
Intervention trials promoting physical activity among older people frequently report low and unrepresentative recruitment. Better understanding of reasons for participation can help improve recruitment. This study explored why participants enrolled in the Coaching for Healthy Ageing (CHAnGE) trial, including how their decision was influenced by recruitment strategies. CHAnGE was a cluster randomised controlled trial testing the effectiveness of a healthy ageing program targeting inactivity and falls. Seventy-two groups of people aged 60+ were recruited from community organisations via informal presentations by the health coaches. We conducted a secondary thematic analysis of interview data from our wider qualitative evaluation in which 32 purposively sampled trial participants took part in semi-structured interviews about their experiences of CHAnGE. Data relating to recruitment and participation were analysed inductively to identify themes, then a coding framework comprising the core constructs from self-determination theory-autonomy, competence and relatedness-was used to explore if and how this theory fit with and helped to explain our data. Recruitment presentations promoted the CHAnGE intervention well in terms of addressing value expectations of structured support, different forms of accountability, credibility, achievability and, for some, a potential to enhance social relationships. Participation was motivated by the desire for improved health and decelerated ageing, altruism and curiosity. These factors related strongly to self-determination concepts of autonomy, competence and relatedness, but the intervention's demonstrated potential to support self-determination needs could be conveyed more effectively. Findings suggest that recruitment could have greater reach using: 1. Strengths-based messaging focusing on holistic gains, 2. Participant stories that highlight positive experiences, and 3. Peer support and information sharing to leverage altruism and curiosity. These theory-informed improvements will be used to increase participation in future trials, including people in hard-to-recruit groups. They may also inform other physical activity trials and community programs.
Exercise for fall prevention in community-dwelling people aged 60+: more effective in trials with higher fall rates in control groups
Exercise is beneficial for fall prevention. Targeting interventions to people who fall more may lead to greater population impacts. As trials have used varying methods to assess participant risk level, prospectively-measured control group fall rates may provide a more accurate and poolable way to understand intervention effects in different subpopulations. We aimed to explore differences in effectiveness of fall prevention exercise according to prospectively-measured fall rate. Secondary analysis of a Cochrane review investigating exercise for fall prevention in peopled aged ≥60 years. Meta-analysis assessed the impact of exercise on fall rate. Studies were dichotomized according to the median control group fall rate (0.87, IQR 0.54–1.37 falls/person-year). Meta-regression explored the effects on falls in trials with higher and lower control group fall rates. Exercise reduced the rate of falls in trials with higher (rate ratio 0.68, 95% CI 0.61–0.76, 31 studies) and lower control group fall rates (rate ratio 0.88, 95% CI 0.79–0.97, 31 studies, P = 0.006 for difference in effects). Exercise prevents falls, moreso in trials with higher control group fall rates. As past falls strongly predict future falls, targeting interventions to those with more past falls may be more efficient than other falls risk screening methods. •Prospective fall rate may more accurately indicate fall risk among study samples.•Exercise interventions are more effective in those with higher fall rates.•Promoting exercise in higher fall rate groups may optimise population level benefits.
Exercise for falls prevention in community-dwelling older adults: trial and participant characteristics, interventions and bias in clinical trials from a systematic review
IntroductionThere is strong evidence that exercise prevents falls in community-dwelling older people. This review summarises trial and participant characteristics, intervention contents and study quality of 108 randomised trials evaluating exercise interventions for falls prevention in community-dwelling older adults.MethodsMEDLINE, EMBASE, CENTRAL and three other databases sourced randomised controlled trials of exercise as a single intervention to prevent falls in community-dwelling adults aged 60+ years to May 2018.Results108 trials with 146 intervention arms and 23 407 participants were included. Trials were undertaken in 25 countries, 90% of trials had predominantly female participants and 56% had elevated falls risk as an inclusion criterion. In 72% of trial interventions attendance rates exceeded 50% and/or 75% of participants attended 50% or more sessions. Characteristics of the trials within the three types of intervention programme that reduced falls were: (1) balance and functional training interventions lasting on average 25 weeks (IQR 16–52), 39% group based, 63% individually tailored; (2) Tai Chi interventions lasting on average 20 weeks (IQR 15–43), 71% group based, 7% tailored; (3) programmes with multiple types of exercise lasting on average 26 weeks (IQR 12–52), 54% group based, 75% tailored. Only 35% of trials had low risk of bias for allocation concealment, and 53% for attrition bias.ConclusionsThe characteristics of effective exercise interventions can guide clinicians and programme providers in developing optimal interventions based on current best evidence. Future trials should minimise likely sources of bias and comply with reporting guidelines.
Active women over 50: study protocol for RCT of a low-dose information and support program to promote physical activity behaviour change
Background There is compelling evidence that physical activity has many physical and mental health benefits and can delay the development of disability in older age. However, uptake of this health behaviour is sub-optimal in working women in their middle age. This trial aims to establish the impact of a low-dose information program, incorporating follow-up support using behaviour change techniques, compared with a wait-list control group, on physical activity among women aged 50+ years. Methods 100 female university or health service employees aged 50 years and over who are not sufficiently active according to national guidelines will be recruited and randomised to: [1] attend one information session at the worksite with follow-up email support and provision of resources including use of an activity tracker ( Fitbit ) for 3 months and free trial class at the university sports facility, or [2] a wait-list control to receive the intervention after the 3-month follow-up period. The primary outcome will be the proportion of people achieving 10,000 steps/day at 3 months post randomisation. Secondary outcomes will include the proportion of people achieving national guideline-recommended physical activity levels, the average self-reported hours of physical activity per week, perceived benefits of and barriers to exercise participation, physical functioning, and mood. Analyses will be planned, conducted while masked to group allocation and will use an intention-to-treat approach. Discussion This randomised controlled trial will evaluate the impact of a simple intervention using behaviour change techniques to increase physical activity participation in insufficiently active working women over the age of 50.

Evidence on physical activity and falls prevention for people aged 65+ years: systematic review to inform the WHO guidelines on physical activity and sedentary behaviour
Background Exercise prevents falls in older adults. Regular updates of estimated effects of exercise on falls are warranted given the number of new trials, the increasing number of older people globally and the major consequences of falls and fall-related injuries. Methods This update of a 2019 Cochrane Review was undertaken to inform the World Health Organization guidelines on physical activity and sedentary behaviour. Searches were conducted in six databases. We included randomised controlled trials evaluating effects of any form of physical activity as a single intervention on falls in people aged 60+ years living in the community. Analyses explored dose-response relationships. The certainty of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results This review included 116 studies, involving 25,160 participants; nine new studies since the 2019 Cochrane Review. Exercise reduces the rate of falls by 23% (pooled rate ratio (RaR) 0.77, 95% confidence interval (CI) 0.71 to 0.83, 64 studies, high certainty evidence). Subgroup analysis showed variation in effects of different types of exercise ( p  < 0.01). Rate of falls compared with control is reduced by 24% from balance and functional exercises (RaR 0.76, 95% CI 0.70 to 0.82, 39 studies, high certainty evidence), 28% from programs involving multiple types of exercise (commonly balance and functional exercises plus resistance exercises, RaR 0.72, 95% CI 0.56 to 0.93, 15 studies, moderate certainty evidence) and 23% from Tai Chi (RaR 0.77, 95% CI 0.61 to 0.97, 9 studies, moderate certainty evidence). The effects of programs that primarily involve resistance training, dance or walking remain uncertain. Interventions with a total weekly dose of 3+ h that included balance and functional exercises were particularly effective with a 42% reduction in rate of falls compared to control (Incidence Rate Ratio (IRR) 0.58, 95% CI 0.45 to 0.76). Subgroup analyses showed no evidence of a difference in the effect on falls on the basis of participant age over 75 years, risk of falls as a trial inclusion criterion, individual versus group exercise, or whether a health professional delivered the intervention. Conclusions Given the strength of this evidence, effective exercise programs should now be implemented at scale.
The minimum sit-to-stand height test: reliability, responsiveness and relationship to leg muscle strength
Objective: To determine the reliability of the minimum sit-to-stand height test, its responsiveness and its relationship to leg muscle strength among rehabilitation unit inpatients and outpatients. Design: Reliability study using two measurers and two test occasions. Secondary analysis of data from two clinical trials. Setting: Inpatient and outpatient rehabilitation services in three public hospitals. Subjects: Eighteen hospital patients and five others participated in the reliability study. Sevety-two rehabilitation unit inpatients and 80 outpatients participated in the clinical trials. Methods: The minimum sit-to-stand height test was assessed using a standard procedure. For the reliability study, a second tester repeated the minimum sit-to-stand height test on the same day. In the inpatient clinical trial the measures were repeated two weeks later. In the outpatient trial the measures were repeated five weeks later. Knee extensor muscle strength was assessed in the clinical trials using a hand-held dynamometer. Results: The reliability for the minimum sit-to-stand height test was excellent (intraclass correlation coefficient (ICC) 0.91, 95% confidence interval (CI) 0.81–0.96). The standard error of measurement was 34 mm. Responsiveness was moderate in the inpatient trial (effect size: 0.53) but small in the outpatient trial (effect size: 0.16). A small proportion (8–17%) of variability in minimum sit-to-stand height test was explained by knee extensor muscle strength. Conclusions: The minimum sit-to-stand height test has excellent reliability and moderate responsiveness in an inpatient rehabilitation setting. Responsiveness in an outpatient rehabilitation setting requires further investigation. Performance is influenced by factors other than knee extensor muscle strength.
Active Women over 50 online information and support to promote physical activity behaviour change: study protocol for a pilot trial
Background Physical activity has many physical and mental health benefits and can delay the development of disability in older age. However, uptake of this health behaviour is sub-optimal in women in their middle and older age. This trial aims to establish the acceptability and feasibility of the Active Women over 50 programme involving online information, telephone health coaching and email or SMS support to promote physical activity behaviour change among women aged 50 years and over. Methods Sixty community-dwelling women who are insufficiently active according to national guidelines, will be recruited and randomised to 1) receive the Active Women over 50 programme or 2) a wait-list control. Active Women over 50 is a 3-month physical activity programme guided by behaviour change science, providing access to a website, one telephone-delivered health coaching session from a physiotherapist and 8 email or 24 SMS messages. The primary outcome is the proportion of participants at 3 months post-randomisation who would recommend participation in the programme to another person like themselves. Secondary outcomes are feasibility measures: rates of recruitment, retention, completeness of outcome data and uptake of telephone support; and intervention impact measures: accelerometer-assessed average steps/day, proportion of participants meeting national guidelines on moderate to vigorous physical activity; and questionnaire-assessed quality of life, exercise perceptions, mood, physical functioning and self-reported physical activity. Intervention participants will also complete a follow-up survey to assess impressions of the intervention and adoption of strategies for physical activity participation. Data will be analysed descriptively to guide the design of a larger trial. Between-group differences in secondary outcomes will be used to estimate effect sizes for sample size calculations for a fully powered randomised controlled trial. Discussion This feasibility pilot trial of an efficient eHealth and health coaching intervention guided by user input and behaviour change theory, will inform future interventions to address low physical activity participation among an under-active group at risk of future disability.
