A scoping review of physical activity interventions for older adults

BACKGROUND

To inform implementation and future research, this scoping review investigates the volume of evidence for physical activity interventions among adults aged 60+. Our research questions are: (1) what is the evidence regarding interventions designed to increase total physical activity in adults aged 60+ years, in accordance with three of the four strategic objectives of GAPPA (active societies, active environments, active people); (2) what is the current evidence regarding the effectiveness of physical activity programmes and services designed for older adults?; and (3) What are the evidence gaps requiring further research?

METHODS

We searched PEDro, MEDLINE, CINAHL and Cochrane from 1 January 2010 to 1 November 2020 for systematic reviews and meta-analyses of physical activity interventions in adults aged 60+. We identified interventions designed to: (1) increase physical activity; and (2) deliver physical activity programmes and services in home, community or outpatient settings. We extracted and coded data from eligible reviews according to our proposed framework informed by TIDieR, Prevention of Falls Network Europe (PROFANE), and WHO's International Classification of Functioning, Disability and Health (ICF). We classified the overall findings as positive, negative or inconclusive.

RESULTS

We identified 39 reviews of interventions to increase physical activity and 342 reviews of programmes/services for older adults. Interventions were predominantly structured exercise programmes, including balance strength/resistance training, and physical recreation, such as yoga and tai chi. There were few reviews of health promotion/coaching and health professional education/referral, and none of sport, workplace, sociocultural or environmental interventions. Fewer reported outcomes of total physical activity, social participation and quality of life/well-being. We noted insufficient coverage in diverse and disadvantaged samples and low-middle income countries.

CONCLUSIONS

There is a modest but growing volume of evidence regarding interventions designed to increase total physical activity in older adults, although more interventional studies with long term follow-up are needed, particularly for GAPPA 1. Active Societies and GAPPA 2. Active Environments. By comparison, there is abundant evidence for GAPPA 3. specific programmes and services, but coverage of sport and workplace interventions, and diverse samples and settings is lacking. Comprehensive reviews of individual studies are now needed as well as research targeting neglected outcomes, populations and settings.

Engineering Improved Balance Confidence in Older Adults With Complex Health Care Needs: Learning From the Muscling Up Against Disability Study

OBJECTIVE

To investigate the associations of balance confidence with physical and cognitive markers of well-being in older adults receiving government-funded aged care services and whether progressive resistance plus balance training could positively influence change.

DESIGN

Intervention study.

SETTING

Community-based older adult-specific exercise clinic.

PARTICIPANTS

Older adults (N=245) with complex care needs who were receiving government-funded aged care support.

INTERVENTIONS

Twenty-four weeks of twice weekly progressive resistance plus balance training carried out under the supervision of accredited exercise physiologists.

MAIN OUTCOME MEASURES

The primary measure was the Activity-specific Balance Confidence Scale. Secondary measures included the Short Physical Performance Battery; fall history gathered as part of the health history questionnaire; hierarchical timed balance tests; Geriatric Anxiety Index; Geriatric Depression Scale; Fatigue, Resistance, Ambulation, Illness, Loss of Weight scale; and EuroQoL-5 dimension 3 level.

RESULTS

At baseline, better physical performance (r=.54; P<.01) and quality of life (r=.52; P<.01) predicted better balance confidence. In contrast, at baseline, higher levels of frailty predicted worse balance confidence (r=-.55; P<.01). Change in balance confidence after the exercise intervention was accompanied by improved physical performance (+12%) and reduced frailty (-11%). Baseline balance confidence was identified as the most consistent negative predictor of change scores across the intervention.

CONCLUSIONS

This study shows that reduced physical performance and quality of life and increased frailty are predictive of worse balance confidence in older adults with aged care needs. However, when a targeted intervention of resistance and balance exercise is implemented that reduces frailty and improves physical performance, balance confidence will also improve. Given the influence of balance confidence on a raft of well-being determinants, including the capacity for positive physical and cognitive change, this study offers important insight to those looking to reduce falls in older adults.
