Physical Activity: Home-based Exercise Interventions for Adults Aged 65 years and Older

CPSTF uses recently published systematic reviews to conduct accelerated assessments of interventions that could provide program planners and decision-makers with additional, effective options. The following published review was selected and evaluated by a team of specialists in systematic review methods, and in physical activity research, practice, and policy.

Chaabene H, Prieske O, Herz M, et al. Home-based exercise programmes improve physical fitness of healthy older adults: a PRISMA-compliant systematic review and meta-analysis with relevance for COVID-19. Ageing Research Reviews 2021;67:101265.

The published review included 17 studies (search period through December 2020). CPSTF abstracted supplemental information about study, intervention, and population characteristics from each of the included studies.

The CPSTF finding is based on results from the published systematic review and meta-analysis, additional information from the included studies, and expert input from team members and CPSTF.

Adults ages aged 65 years and older gain substantial health benefits from regular physical activity. Physical activity can preserve physical function and mobility, which may delay the onset of major disability and help older adults maintain independence longer (U.S. Department of Health and Human Services 2018). Exercises for muscle strength and balance combined with aerobic activities, such as walking, are important components of an overall weekly routine for older adults to reduce physical inactivity and maintain fitness (U.S. Department of Health and Human Services 2018).

Isolation in response to heightened risk for community-acquired infectious disease may reduce opportunities for older adults to be physically active and increase the amount of time they spend in sedentary behaviors (Ammar et al 2020). Training and supporting older adults in establishing regular exercise routines at home may help them limit physical inactivity and improve or maintain fitness during periods of time when they are advised to stay home (Chaabene et al. 2021).

The published systematic review and meta-analyses included 17 studies.

• Older adults demonstrated small but statistically significant improvements in measures of physical fitness including balance (14 studies), muscle strength (10 studies), muscle power (4 studies), and muscular endurance (4 studies).
• Studies examined effectiveness of multimodal (e.g., strength and balance exercises; 11 studies) or single mode exercise interventions (strength only, 5 studies; balance only, 1 study). Single mode strength training resulted in larger effects on both muscle strength and balance than multimodal interventions.

CPSTF examined additional data reported in the included studies.

• Participants reported fewer falls and fall-related outcomes (5 studies) and more time spent engaged in physical activity overall (2 studies). Findings were mixed for self-reported improvements in quality of life (5 studies) and time spent in aerobic activities (2 studies).
• Studies found no differences in measures of mental health (2 studies).

A systematic review of economic evidence has not been conducted.

Based on the results from the review, findings should be applicable to the general population of older adults aged 65 years and older in the United States. Additional studies are needed, however, to evaluate effectiveness of home-based exercise interventions for participants from historically disadvantaged racial and ethnic populations and populations with lower incomes.

CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)

CPSTF identified the following questions as priorities for research and evaluation:

• How effective are home-based exercise interventions for participants from historically disadvantaged racial and ethnic populations?
• How effective are home-based exercise interventions for participants with lower incomes?

Remaining questions for research and evaluation identified in this review include the following:

• How does effectiveness vary by age for participants aged 65 years and older?
• How do risks for exercise-associated injuries vary by age for participants aged 65 years and older?
• How does effectiveness vary for participants with physical or cognitive disabilities?
• What strategies are effective to increase recruitment of men in home-based exercise interventions?
• What are the effects of home-based exercise interventions on the following outcomes?
  • Falls prevention
  • Mental health outcomes
  • Quality of life outcomes
  • Morbidity and mortality

• Included studies were randomized trials (17 studies).
• Studies were conducted in the United States (4 studies), Japan (3 studies), and the United Kingdom (2 studies); one study each came from Canada, Denmark, Finland, Germany, Greece, Italy, Taiwan, and Iran.
• Studies recruited participants in the community (10 studies), clinical settings (6 studies), and a residential care center (1 study).
• The median age of study participants was 73 years (17 studies)
• Studies recruited both males and females, however more participants were female (67%) than male (43%).
• Interventions were delivered by physiotherapists and physical therapists (6 studies), trained intervention providers (6 studies), peer mentors (1 study), and nurses (1 study).
• Training, supervision, and monitoring included home visits (8 studies), telephone calls (9 studies), training logs or diaries (15 studies), or other types of communication (e.g., lab or clinical visits; 3 studies).
• Study interventions also reported engaging participants in walking (8 studies), flexibility exercises (4 studies), and other types of activities such as gardening (2 studies).

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

A summary evidence table for this Community Guide review is not available because the CPSTF finding is based on the following published systematic review:

• Physical Activity Guidelines for Americans (2^nd edition) recommends multicomponent physical activities for older adults that include more than one type of activity (e.g., aerobic, muscle strengthening, balance training). Multicomponent physical activity can be done at home or in a community setting as part of a structured program that includes a combination of balance, muscle strengthening, and aerobic physical activity. Programs also may include gait, coordination, and physical function training (U.S. Department of Health and Human Services 2018).
• Chaabene et al. focused on studies that measured muscle strengthening and balance. These interventions can complement support for aerobic activities, such as walking, to achieve the recommended multicomponent approach for older adults (U.S. Department of Health and Human Services 2018).
• The following CPSTF recommendations may be used to support or complement the use of home-based exercise interventions:
  • Digital Health Interventions for Adults 55 Years and Older
  • Park, Trail, and Greenway Infrastructure Interventions when Combined with Additional Interventions
• Digital technologies may enhance home-based activities by providing social contact and support typically available in face-to-face and group-based activities (Parker et al. 2021; Lindsay Smith et al. 2017).
• Several publicly available resources provide guidance on the implementation of exercise and physical activity interventions for older adults.
  • CDC’s Active People, Healthy Nation^SM provides community-level guidance on strategies to improve physical activity and tools for action.
  • The Otago program provides guidance for 17 strength and balance exercises and a walking program, designed to be performed three times a week in home settings.
  • Community Healthy Activities Model Program for Seniors (CHAMPS) outlines an individually-tailored program appropriate for older adults with a range of health levels to increase physical activity.
  • Active Choices includes implementation guidance for a 6-month individualized physical activity program that helps individuals incorporate preferred physical activities in their daily lives.
