Association of the built environment with physical activity in children and adolescents in Africa: a systematic review protocol

Objective: The objective of this systematic review is to summarize the association between the built environment and physical activity in children and adolescents in Africa. Introduction: Physical activity offers immense benefits to children and adolescents. Some built environment constructs, such as street connectivity and the availability of parks, have been identified to facilitate physical activity in children and adolescents; however, this evidence has come from developed countries. This review will present evidence from Africa on the built environment constructs that facilitate physical activity in children and adolescents. Inclusion criteria: This review will consider quantitative studies that have built environment constructs as one of their exposure variables and physical activity as one of their outcomes and were conducted in children and adolescents aged five to 19 years residing in Africa. Methods: A systematic search of MEDLINE, Embase, Web of Science and other sources will be conducted to locate both published and unpublished studies. There will be no date or language restrictions. Titles, abstracts, and full text of articles retrieved from the search will be screened and read by two reviewers independently for eligibility. Included articles will be critically appraised independently by two reviewers. Data extraction will be performed in two phases, first for information regarding the study characteristics and then to extract specific study findings. Meta-analysis will be used to synthesize the findings from the studies; however, where this is not possible, a narrative synthesis will be performed. Systematic review registration number: PROSPERO CRD42019133324.
