Introduction: Large for date (LGA) infants may have a higher tendency to become obese and tall. Catch-up and/or catch-down in linear growth, defined as an increase or decrease in length for age Z score (LAZ) by > 0.67 SD during the infantile period, may affect this tendency. Additionally, head circumference is well correlated with brain growth.

Aim: We evaluated the prevalence of tall stature (LAZ > 1 and> 2) and large head (HCZ > 1 and >2) in a cohort of infants (n = 87) born large-for-gestational-age at age 2 years. We compared the prevalence of tall stature and large head in those who had significant catch down > - 0.67 SD during infancy to those who did not have catch down.

Results: The prevalence of tall stature (LAZ > 1 and > 2) was significantly higher in the LGA group who did not have significant catch-down during infancy. (Table 1) The prevalence of large head (HCZ > 1 and > 2) was higher in LGA children who did not have significant catch-down during infancy. (Table 2)

Conclusion: According to our data, term LGA infants with no catch-down growth had an increased incidence of tall stature and large head size compared to those with significant catch-down growth. A large percentage of LGA infants have relatively large heads at 2 years of age.
