Popis: OBJECTIVES Developmental milestones norms are widely used worldwide and are fundamental for early childhood developmental surveillance. We compared a new Israeli evidence-based national developmental scale with the recently updated Centers for Disease Control and Prevention (CDC) checklists. METHODS We used a cohort of nearly 4.5 million developmental assessments of 758 300 full-term born children aged 0 to 6 years (ALL-FT cohort), who visited maternal child health clinics in Israel for routine developmental surveillance. Among the assessed milestones of 4 developmental domains (gross motor, fine motor, language, and personal–social) we identified milestones that had equivalents on the CDC checklists and assessed the attainment rates of the Israeli children at the ages recommended by the CDC, at which ≥75% of the children would be expected to achieve the milestone. The analysis was repeated on a subgroup of 658 958 children who were considered healthy, typically developing by their birth and growth characteristics (NORMAL-FT cohort). RESULTS There were 29 milestones, across all developmental domains and assessment ages, whose definitions by both tools were compatible, and could be compared. The attainment rate at the CDC-recommended age was >90% for 22 (76%) and 23 (79%) milestones, and the median attainment rates were 95.2% and 96.3% in the ALL-FT and NORMAL-FT cohorts, respectively. CONCLUSIONS For almost all comparable milestones of all domains and all ages, children of the Israeli cohorts achieved the milestones earlier than expected by the CDC-defined threshold age. Evidence-based analysis of milestone norms among different populations may enable adjustments of developmental scales and facilitate more personalized developmental surveillance.
