Abstract Objective To compare children’s development milestones between China and the United States of America, and provide basic reference for development surveillance and screening. Methods From March 2018 to November 2021 , 437 671 children, aged 1 -36 months, who received routine physical examination in the Department of Child Health of hospitals in China were enrolled in this study. Their development status was evaluated with infant andtoddler growth development screening test（ITGDST）. The pass rates of corresponding development items were calculated by using 75 % cut-off values. The children’s developmental milestones were compared between China and the United States of America. Results There were 126 milestones in 10 checklists for children aged 2-36 months in the United States ofAmerica, 35（27.8%）of which completely matched items in ITGDST. Among the 35 matched items, the pass rates of 33 items（94.3%）were higher than 75 %, while the pass rates of the other 2 items（5.7%）were lower than but close to 75%. Motor domain accounted for the most with 16 items（45.7%）, followed by language with 8 items（22.9%）, cognition with 6 items（17.1%）, and social interaction with 5 items（14.3%）. There were six developmental milestones that Chinese children reached 1-2 months earlier than American children. Conclusion The consistency of developmental milestones among the matched items was high for the children aged 2-36 months of China and the United States of America. The revision of development milestones for children of the United States of America may also be applicable to developing countries. Incorporating more monthly developmental checklists may facilitate early warnings and early interventions.
