Abstract: Objective To understand the status of responsive feeding of preterm infants during food conversion period,in order to provide theoretical evidence for the appropriate and scientific feeding. Methods Totally 268 preterm infants aged 18 months (including 60 high-risk infants,55 moderate-risk infants and 153 low-risk infants) were recalled for the study from January to December 2018.And 117 full-term infants in the meantime were chosen as control.A retrospective survey was conducted,and the data were analyzed by chi-square test or one-way analysis of variance. Results 1) The proportion of adverse feeding behaviors in preterm infants was higher than that in full-term infants.Among three feeding behaviors,mixed feeding behavior accounted for the highest proportion.Weight and height under adverse feeding behavior were lower than those under good feeding behavior at the age of 18 months.2) Preterm infants had more complementary meals than full-term infants at the corrected age of 4-5 months old and 6 months old (F=75.86,26.75,P<0.05),and totally 35.4% of them did not follow the recommended time to arrange complementary meals.3) The proportion of feeding difficulty in preterm infants was significantly higher than that of full-term infants (46.6% vs.35.0%,P<0.05). Conclusion Preterm infants are prone to suffering from adverse feeding behaviors,inappropriate complementary meal arrangements and feeding difficulty during food conversion period.
