Mapping food and physical activity environments in low- and middle-income countries: A systematised review

This systematised literature review synthesised evidence on approaches to mapping food and physical activity (PA) environments in low- and middle-income countries (LMICs). Of the 60 articles included, 25 and 35 mapped food and PA environments respectively. All studies were cross-sectional with researcher-led data collection. Three types of mapping tools were identified - maps (n = 18), GPS (n = 10), and GIS (n = 37). Our findings point to a paucity of research mapping food and PA environments, overall and particularly subjective domains. We highlight a need for future studies that utilise innovative, inexpensive and participatory research methods to understand dynamic exposures to obesogenic environment features in resource-constrained contexts undergoing rapid urbanisation.
