Association of developmental coordination disorder with early-life exposure to fine particulate matter in Chinese preschoolers
Graphical abstract
Although fine particulate matter (PM2.5) is a neurotoxicant, little is known about whether early-life PM2.5 exposure is associated with an increased risk of developmental coordination disorder (DCD). We conducted a cohort study of 109 731 children aged 3–5 years from 551 county-level cities in China between April 2018 and December 2019. Residential PM2.5 exposure was estimated using a hybrid satellite-based exposure model. Children’s motor performance was assessed using the Little DCD Questionnaire (LDCDQ).
