Research evidencesupports the significant associations between motor skills performance and levels of PA, andthe influences of environmental factors in healthy children. Although preterm children areoften characterized by motor deficits in early years, little is known about the developmentaltrajectory of PA in preterm population and its possible relations with motor competence andenvironmental support. The purposes of this 3-year research project are to investigate theassociations between physical activity level, motor skills performance, and environmentalaffordances in young children during 2 to 4 years of age, and to examine how these relationsmay be impact by preterm birth. Sixty preterm and thirty full-term children will berecruited. Children will enter to the study at 2 years of age and will be followed every 6months until 4 years of age. PA will be measured objectively and quantitatively usingaccelerometry. Motor competency will be assessed with Peabody Developmental MotorScales, Second Edition (PDMS-2). Physical and social aspects of the home environment willbe assessed using the Chinese version of Affordance in the Home Environment for MotorDevelopment (AHEMD-C). The results of this project will help identify the mechanisms andmediating factors that explain inactivity in young children, especially those born preterm, aswell as provide useful information for early intervention and policy making.
