ASSOCIATIONS BETWEEN THE LIVING ENVIRONMENT AND SLEEP THROUGH THE MEDIATION OF THE PHYSICAL ACTIVITY: A SYSTEMATIC REVIEW PROTOCOL

Objective: To obtain a comprehensive understanding of the role of physical activity as a
mediator variable in the association between the living environment and sleep.
Material and methods: The systematic review protocol has been published on PROSPERO [ID:
CRD42024580376]. The PRISMA 2020 guidelines will be followed throughout the process. This
systematic review will include both experimental and observational studies in English that
focus on how physical activity mediates the relationship between the living environment and
sleep in humans, regardless of age, gender or ethnicity. The literature search will be conducted in Medline (via Pubmed), Scopus and Embase, using both controlled language and free text to formulate the search equations. Additional manual searches will also be realized. Studies will be imported into the Covidence software for duplicate removal, and selection will be conducted by two independent reviewers based on titles, abstracts, and full-text articles, providing detailed reasons for exclusion. Data extraction will be performed independently by two reviewers, while the methodological quality of the studies will be assessed using the critical appraisal tools for use in JBI Systematic Reviews.
Results: We expected to obtain the results of the systematic review during 2025.
Conclusion: Identifying elements of the living environment that influence sleep through the
mediation of physical activity is essential for public authorities to develop effective strategies
in public health, housing, and territory planning. Highlighting the role of physical activity in
this association can guide targeted interventions to improve both sleep health and, more
broadly, overall health status.
