Air Pollution, Not Diet, Shows the Strongest Link to Poorer Concentration in Schoolgirls

In a recent study published in BMC Public Health, researchers investigated the joint and individual effects of air pollution exposure and dietary antioxidants on concentration and memory in young female Iranian students.

Higher levels of dietary antioxidants and lower exposure to air pollution were both significantly associated with better concentration performance, with air pollution showing the most consistent association across fully adjusted statistical models, while no significant interaction or direct association was observed for short-term memory outcomes.

Background: Cognitive Development, Diet, and Environmental Exposure

Short-term memory and concentration are foundational cognitive processes that strongly influence children’s learning and academic performance, as well as outcomes in later life. Short-term memory supports information retention over brief periods, while sustained attention enables task engagement and error control.
