Sleep behavior of preterm children at three years of age.

Abstract

Caregivers of 50 preterm children completed a questionnaire relating to their child's sleep behavior at three years of age. Assessments of the children's EEGs at term and three months, medical status at birth and at four, nine and 24 months, caregiver-child interaction at one, eight and 24 months, the Bayley Scales at 25 months and the Stanford-Binet at five years of age were also obtained. Sleep disturbances were frequently noted at three years of age. However, by five years of age, the number of reported sleep-problem children was greatly reduced, and they were not the same children with sleep problems at three years. Surprisingly, children with the greatest difficulty falling asleep at night at three years were likely to have had fewer medical problems, higher scores on the Bayley scales, and more positive social interactions with their caregivers in the first two years. The relationships among early physical, psychological and social development and sleep behavior are discussed.
