Gross Motor Development in Jamaican Infants

Abstract
SUMMARY: Some items of gross motor and language development behaviour were evaluated in 300 Kingston, Jamaica, infants of predominantly Negro extraction throughout the first year of life. They were found to be accelerated over the normal white child of the Gesell Developmental Schedules. Children of low birthweight were significantly slower than the remaining children in attaining several items but were equal to the normal white child of the Gesell Schedules. Sex and socio‐economic class made no difference to the age of walking, although high weight at 12 months had a beneficial effect.
