Abstract: Objective To study the physical and neuropsychological development of corrected age 5-7 month premature infants and analyze the correlation between them.Methods Using the developed Internet + premature infant follow-up system to set up a sharedcare model for premature infants. From 2019,follow-up of premature infants born in our hospital and referrals in our area was carried out according to the Work Standard of Premature Infant Health Care. The physical and neuropsychological development of preterm infants at corrected age 5-7 month and the correlation between them were analyzed.Results There were 53(27.0%) premature infants with extrauterine growth retardation at corrected age 5-7 month. The weights of nine(45.0%) small for gestational age infants and 22(12.7%) suitable for gestational age infants failed to achieve satisfactory catch-up growth at corrected age 5-7 month. While 32(16.3%) preterm infants with overweight catch-up growth. Twenty-five preterm infants(12.8%) had abnormal or approximate abnormal neural development in at least one zone at the corrected age of 5 to 7 months(developer ≤ 79). When they were evaluated by the Neuropsychological and Behavioral Examination Scale for Children aged 0-6 Years Old(2016) corrected age 5-7 month,the average weight and length of them were lower than those in the normal development group. The differences were statistically significant(P<0.05).Conclusion The neuropsychological development was related to the physical development in preterm infants at corrected age 5-7 month. The scientific management of nutrition of premature infants after discharge is the basis to ensure the normal development of their neuropsychological development.
