Hand Preference Develops Across Childhood and Adolescence in Extremely Preterm Children: The EPICure Study.

ABSTRACT:

Aim

We attempted to determine how handedness changes with age and its relation to brain injury and cognition following birth before 26 weeks of gestation.

Methods

We used data from the EPICure study of health and development following birth in the British Isles in 1995. Handedness was determined by direct observation during standardized testing at age 2.5, six, and 11 years and by self-report using the Edinburgh Handedness Inventory at 19 years. Control data from term births were included at six, 11, and 19 years.

Results

In extremely preterm children left handedness increased from 9% to 27% between 2.5 and 19 years, with a progressive reduction in mixed handedness from 59% to 13%. Although individual handedness scores varied over childhood, the between-group effects
