| Objective:To study the influence of motor and physical growth development of very low birth weight infants(VLWBI) after early comprehensive intervention within infancy period, which was compared with premature infants(PI), we observed the differences between them.Methods:35 VLBWI,hospitalized from July 2012 to July 2013 in NICU of Affiliated Hospital of Chengde Medical College with complete follow-up data,were selected as intervention group(IG); And 40 normal healthy PI born in the same hospital’s obstetrical department within the same period with complete follow-up data were as control group(CG). Both groups were given to the same scientific feeding and parenting, such as assist food adding, iron supplementation, the prevention and treatment of common disease. In addition, IG was given to systematic comprehensive practice interventions, including touching, baby hearing and looked up, rolling over, sitting, crawling, standing in sports training and etc. Statistical induction and t test were used between two groups respectively in 3 months, 6 months, 9 months and 12 months about physical and P-body motor development. Physical development was evaluated by 0-36 month head-circumference for age and weight-for-length percentiles. Motor development assessment was evaluated by PDMS-2 scale. The age of VLBWI who were less than 24 months need correct age. Assessment result was expressed by Great Motor Quotient and Fine Motor Quotient and Total Motor Quotient. The data was analyzed by SPSS 17.0 software. Measurement data was analyzed by t test between two groups. Categorical data was analyzed by chi-square test. Difference was considered to be statistically significant at P<0.05.Results:There were significant differences in the physical and motor development of PI among the age of birth, 3 and 6 month(P<0.05).There was no significant difference among the body length, weight and P-body motor development at the age of 9 months, except that head circumference of VLBWI were basically completed the catching-up growth. There was no significant difference between VLBWI and PI at the 12 months among all aspects. VLBWI of physical and P-body motor development had reached the level of PI and complete a catch-up growth target.Conclusion:Through the study of early intervention to VLBWI, we could find that the physical and motor development of intervention group were lag behind control group from birth to six months, while the differences were decreased as the growth of months. The results showed that rational and scientific guiding for feeding, according to the retardation for intensive training, such as touching, baby practice, vision tracking, balance blocks, shafting head, rolling over, sitting alone and so on, could make a rapid chasing of VLBWI in spite of lagging behind of control group. This illustrated that the need of maintaining a long time for catching-up-growth, and the demand of persistent intervention of parents and medical staffs. The length and weight of VLBWI had reached the standard of control group at the age of nine months, which indicated that it was important for VLBWI of long-term reasonable nutritional guidance and strengthen the training of various thickness. A full range of passive exercise, activity in sports training and nutrition support, and the active cooperation and good compliance of parents were also indisputable, while head-circumference failed to control group at this stage, which indicated that the speed of brain development was relatively slowly compared with PI. At birth, the brain of VLBWI is immature. The fastest time of brain development is from birth to 36 months. Reasonable stimulus and intervention were beneficial to the development of structure and function of brain. The physical and motor development of VLBWI had run up to the level of control group at twelve months. Parts of the development of VLBWI were even better than the control group. Therefore, VLBWI can fulfill a catching-up growth in one year through comprehensive, reasonable and sustainable comprehensive intervention. |
