| Research Abstract |
The purpose of this study were to identify 1) the characteristics of sleep behaviors assessed from activity data among very low-birth weight (VLBW) preterm infants in comparison to full-term infants, 2) the relationship between sleep behaviors and parenting stress. Cross-section analysis showed that less sleep duration and high activity score during night time among preterm infants at the age of 12 corrected month. However, nocturnal sleep duration improved at the age of 18 corrected month. Longitudinal analysis showed that infants in both group showed the improvement of nocturnal sleep measures. The results of parenting stress index showed that parenting stress of preterm group was significantly higher the one of full-term group.
