Abstract 【Abstract】 Objective To compare the effects of different strengthening nutrition strategies on growth including weight, length and head circumference, and neurobehavioral development at 1 to 6 months of preterm infants with extrauterine growth restriction (EUGR) after discharge, so as to provide a basis for further optimizing the nutrition program of preterm infants with EUGR after discharge. Methods 178 preterm infants with EUGR hospitalized and discharged from NICU in the First People's Hospital of Lianyungang from January 2016 to December 2018 were collected. The preterm infants were randomly divided into two groups. Group A were given full dose enrich nutrition until they reached 40 weeks corrected gestational age and half dose enrich nutrition until they reached 6 months corrected age, while group B were given full dose enrich nutrition until their weight index reached the 10th percentile on growth charts with corrected age and half dose enrich nutrition until their weight index reached the 25th percentile on growth charts with corrected age. The two groups were evaluated and compared with growth index when they reached 40 weeks in corrected gestational age and 1 to 6 months in corrected age. And they were evaluated and compared with neurodevelopment index when they reached 6 months in corrected age. The statistical methods used independent sample t test and χ2
test. Results The differences of growth indexes between the two groups were not significant at 40 weeks corrected gestational age and 1 month corrected age (P>0.05). Group A had gained significantly more weight, length and head circumference than group B at 2 months corrected age [weight (4 692±196) vs (4 630±211)g, length (55.7±0.8) vs (55.3±0.9) cm, head circumference (37.4±0.6) vs (37.0±0.6) cm, P<0.05]. Group A had gained significantly more weight, length and head circumference than group B at 3 months corrected age (P<0.05). Group A had gained significantly more weight, length and head circumference than group B at 4 months corrected age [weight (6 480±305) vs (6 385±270) g, length (63.1±1.2) vs (62.0±1.1) cm, head circumference (40.4±0.7) vs (40.1±0.6) cm, P<0.05]. Group A had gained significantly more weight, length and head circumference than group B at 5 months corrected age (P<0.05). Group A had gained significantly more weight, length and head circumference than group B at 6 months corrected age [weight (7 643±359) vs (7 452±305) g, length (66.1±1.3) vs (65.7±1.0) cm, head circumference (42.2±0.7) vs (42.0±0.6) cm, P<0.05]. The neonatal behavioral neurological assessment scores and abnormal rate of premature infants in groups A and B at 40 weeks corrected gestational age showed no statistical significance (P>0.05). There was no significant difference in abnormal rate of Gesell score, physical ability, language ability, or human ability scores between the two groups of premature infants at 6 months corrected age (P>0.05). Compared with group A , group B showed significantly backwardness at 6 months corrected age in gross motor and fine
motor level (P<0.05). Conclusions The strengthening nutritional strategies adopted by the two groups can help preterm infants with EUGR to catch up with their growth. Full dose enrich nutrition until they reached 40 weeks corrected gestational age and half dose enrich nutrition until they reached 6 months corrected age shows a clear advantage in physical development, but the short-term advantage in neurodevelopment is not obvious.
