Developmental Characteristics of Infants According to their Gestational Age and Birth Weight

초록

[Purpose] This study investigated to look at developmental characteristics of infants at a post-conceptual age of around 40 weeks and compared them with weight and gestational age. [Subjects and Methods] The subjects were 51 full-term and preterm infants, classified into three different subgroups according to birth weight groups (appropriate for gestational age; low birth weight; very low birth weight) and gestational age groups (38 weeks or older; between 32 and 37 weeks; less than 32 weeks). Infants were measured for movement and posture using the Test of Infant Motor Performance and the assessment was performed at the postconceptional age of 40 weeks (mean age: 39.75 weeks). [Results] Head in Midline (O-1) had differences according to birth weight only, and Isolated Rt. Ankle Movement (O-7) had differences according to gestational age only. Only the three gestational age groups showed in head control-posterior neck muscles (E-3). Therefore, developmental characteristics were little different according to birth weight or gestational age. [Conclusion] Regardless of the birth weight or gestational age, there appeared to be no differences in the development evaluation results.
