ABSTRACT
Objective: To investigate the intelligence development of the low birth weight babies and related factors. Method: The development ability of 190 low birth weight babies was assessed with the Revised Gesell Development Schedule. The result was compared with that of normal control. Result: The development quotients (DQ) of low birth weight infants in motor, adaptive and personal/social areas at 1 and 2 years of age and in language at 2 years of age were significantly lower than that of the normal controls. The stepwise regression analysis showed that all performances in motor, adaptive, language and personal/social areas were significantly related to age, sex, head circumstance, low birth weight and feeding way of infants, and education of their parents. Conclusion: Low birth weight infants have poorer intelligence at the age of 1 and 2 years than normal controls.
