The aim of our study is to describe the neuromotor development of preterm and low birth weight infants at 1 and 2 years of corrected age, and to examine the extent to which perinatal, neonatal, socio-demographic, and neuromotor development indices measured at the age of 1 are able to predict infants' development indices at the age of 2. Our sample consisted of 140 infants; developmental examinations were carried out using Bayley-III Screening and Diagnostic Tests. We gathered information by retrospectively reviewing newborns' hospital discharge papers as well by applying a self-devised questionnaire. Our statistical analyses suggest that our multivariate linear regression models possess adequate explanatory power (R 2  = 50-90%): it can be established that, of all development indices at year 1, for all outcome variables (Cognitive, Language, Motor, Social-Emotional, and Adaptive Behaviour Scales at the age of 2), Receptive and Expressive language communication showed outstanding explanatory power.
