Associations of birth size, infancy, and childhood growth with intelligence quotient at 5 years of age: a Danish cohort study.

ABSTRACT:

Background

The correlates of prenatal and postnatal growth on Intelligence Quotient (IQ) in childhood in term-born children living in high-income countries are not well known.

Objectives

We examined how birth size and growth in infancy and childhood were associated with IQ at age 5 y in term-born children using path analysis.

Methods

The study sample comprised 1719 children from the Danish National Birth Cohort who participated in a substudy in which psychologists assessed IQ using the Wechsler Primary and Preschool Scales of Intelligence-Revised. Measured weight, length/height, and head circumference at birth, 5 mo, 12 mo, and 5 y were included in a path model to estimate their total, indirect, and direct effects on IQ. All growth measures were included in the model
