Barriers and motivators to promotion of physical activity participation for older adults with mild cognitive impairment or dementia: An umbrella review

Abstract

Background: Due to the growing aging population worldwide, cognitive disorders including mild cognitive impairment and dementia is considered a major public health priority. Currently, physical activity is a promising non-drug therapy, however, people with mild cognitive impairment or dementia are more likely to be physically inactive.

Objective: To identify the barriers and motivators affecting participation in physical activity in older people with mild cognitive impairment or dementia.

Design: An umbrella review.

Methods: The Joanna Briggs Institute (JBI) methodology for umbrella reviews was adopted in this study. We searched the PubMed, Embase, Web of science, CINAHL, Cochrane, Scopus and Proquest to identify relevant articles published in English from inception to October 2022. Two researchers independently screened and selected articles against preselected inclusion criteria. Eligible studies were appraised for methodological quality using the combined Meta Quality Appraisal Tool and Assessment of Multiple Systematic Reviews Tool. The Grading of Recommendations Assessment Development and Evaluation- Confidence in the Evidence from Reviews of Qualitative Research tool was employed to determine the confidence level in the evidence of the extracted factors. Theoretical Domain Framework (TDF) was used to map barriers and motivators to physical activity participation. Behavior change techniques (BCTs) was utilized to develop theoretically-informed implementation strategies.

Results: Fourteen relevant reviews (covered over 219 primary studies) were included in this review. A total of 31 factors were identified from the selected reviews. Three factors with the strongest supporting evidence for their influence on participation were: resources/material resources, social support, and perceived competence. According to the behavior change techniques, six implementation strategies (providing supervision, developing tailored interventions, providing safe and promoting environment, helping to increase participants' motivation and adherence, integrating all kinds of social support, and providing suitable staffing) were developed.

Conclusions: The evidence presented in this umbrella review suggests that a multilevel stakeholder approach and a system-wide viewpoint should be adopted. Through the Theoretical Domain Framework, we not only identified construct factors for future interventions, but also revealed understudied fields in this research areas. This umbrella review generates data that is expected to inform the development of implementation strategies based on the intervention-mapping approach, which will promote participation in physical activity.

Registration: This study was registered with the PROSPERO (CRD42022371535).
