Abstract: ObjectiveTo investigate the effect of individualized situational exercise training on physical, cognitive and motor function development of late preterm infants in order to provide theoretical and practical evidence for the early development intervention of late preterm infants.MethodsTotally 92 infants were randomly recruited from outpatient clinic for high risk children at Dalian maternal and child health care hospital from June to September in 2018. They were randomly divided into control group(45 cases) and intervention group(47 cases). The control group received routine medical follow-up, and the intervention group received individualized situational exercise training on the basis of routine care. Their physical, cognitive and motor function were compared between two groups at 6,12 and 18 months of corrected age.ResultsThe infants in both groups completed all follow-up visits on time. 97. 7%children in the intervention group completed training course, and their length, weight and head circumference were significantly better than the control group at 6, 12 and 18 months of corrected age(P< 0. 05). In addition, children in the intervention group had better cognitive and motor functions than those in the control group(P< 0. 05).ConclusionIndividualized situational exercise training for late preterm infants can improve physical, cognitive and motor function development, which is worthy of clinical application.
