BACKGROUND Preterm (PT) birth and low birth mass (LBW) can impair growth and development of children and may therefore affect their physical performance up to adulthood. AIMS Our aim was to evaluate long-term consequences of prematurity, especially (an)aerobic exercise capacity and agility up to adulthood, by comparing premature and full-term (FT) individuals. STUDY DESIGN, SUBJECTS From 474 subjects born in 1987, who were enrolled into a longitudinal study, 396 (178 PT and 218 FT (with 127 of them LBW)) were followed-up into their early adulthood. Their mass, respiratory status at birth, and results of SLOfit monitoring system (i.e. results of exercise capacity and agility) were monitored on a yearly basis from their age of 8 to 18years. Data were compared statistically with Student t-test or ANOVA. OUTCOME MEASURES, RESULTS PT (or LBW) individuals performed aerobic (time of 600-meter run of females) and the majority of anaerobic tests (sit-ups, standing broad jump, and time of 60-meter run, but not bent arm hang) worse (p<0.05) than FT individuals. Before puberty, however, the agility and fine motor tests (arm plate tapping, polygon backwards, and standing reach touch) were performed better (p<0.05) by PT (or LBW) females, as compared to their FT peers, with no similar results in males. CONCLUSIONS Our results clearly demonstrate that prematurity (especially extreme prematurity) diminishes exercise capacity and agility on the long-term scale, therefore, PT children should be encouraged towards more regular participation in physical activities from early childhood onwards.
