- Existing developmental surveillance tools are applied identically to both sexes, although male and female children exhibit differences in various aspects.
- In this study, we assess the potential need for a paradigm change from unified to sex-specific developmental scales.
- Using a large cohort, we describe sex-related differences in attainment rates of developmental milestones.
- We construct separate developmental scales for males and females and evaluate their potential effect on the surveillance process.
To explore sex-related difference in attainment rates of developmental milestones and to evaluate the clinical need for separate sex-specific scales.
There are substantial sex-related differences in norms of developmental milestone attainment. Our findings highlight the clinical need for a paradigm change in early childhood developmental surveillance by utilizing sex-specific scales.
