Abstract
Purposes: This study was aimed for three purposes: (1) to assess full-term Taiwanese infants from 6 to 24 months of age using the Bayley Scales of Infant Development—Second Edition (BSID-II) and to compare the data of Taiwan with the normative data established in the United States (US); (2) to examine the potential influencing factors for mental and motor development in full-term Taiwanese infants; and (3) to explore the developmental trajectory of full-term Taiwanese infants during age period of 6 to 24 months. Methods: Five hundred and seven normal full-term infants born in various regions in Taiwan were prospectively examined the BSID-II at 6, 12, 18 and 24 months of age. Twelve hospitals located at the west side of the country participated in the study. Results: The Bayley Mental and Motor raw scores of the full-term Taiwanese infants were significantly lower than those of the US infants across ages. Significant influencing factors identified for infants’ mental development included age, gender, geographical region, and paternal education and occupation; while that for infants’ motor development was age only. Within the mental and motor development, normal performance showed high stability across ages; while delayed performance showed high probability of transition to normal performance during the follow-up. Mental delay was concurrently and consecutively associated with motor delay and vice versa. Furthermore, noncomorbid and comorbid mental and motor delay showed high degree of stability at later ages. Conclusion: Our results suggest that interpretation of the BSID-II results of Taiwanese infants may consider using the data of this study as the standard. Furthermore, full-term Taiwanese infants exhibit complexity in stability as well as comorbidity in mental and motor development during the age period of 6 to 24 months.
