Xin J, et al. - Researchers conducted this systematic review to explore the connections between convenience store access and dietary behaviors and weight status of children (aged 6 to 12 years). They searched and filtered relevant literature published prior to January 1, 2019, in PubMed, Embase, Web of Science, and Cochrane Library. After reviewing 41 included studies conducted in 8 countries, the density of and proximity to convenience stores in children's residential and school neighborhoods were positively linked to unhealthy eating behaviors. Their associations with the weight status of children, however, varied significantly across regions. It was discovered that the link between convenience store access and child weight status in Canada was negative, rather blended in the United States and the United Kingdom, and not significant in East Asia. The authors propose future studies to obviously define the convenience store, better measure access to convenience store, and also measure children's journey and behaviors in food purchase and consumption, explaining pathways from convenience store access to childhood obesity to design efficient interventions and policies.
