Outline of Final Research Achievements

We conducted a prospective cohort study on pregnant women and their children who visited and gave birth at an obstetric hospital. We examined the relationship between the unbalanced size of the head and the development (gross motor, fine motor, visual reception, receptive language, expressive language) of the baby at birth. As a result, the unbalanced size of the head (head circumference ÷ birthweight) at birth has a negative effect on the development of the expressive language, and the unbalanced large head size baby was confirmed to be delayed in the development of gross motor and expressive language at 24 months. Furthermore, the thin mothers (BMI <18.5) before pregnancy revealed that the risk of children with the unbalanced head size is 2.5 times greater than that of the other mothers.
