Abstract: Objective To investigate the language retardation of high-risk infants at the age of 2 years,in order to provide scientific basis for early diagnosis,early intervention and improvement of prognosis. Methods A total of 64 high-risk infants were selected as participants,who received treatment and were followed up to 24 months old in Department of Pediatric in Shanghai Changhai Hospital from June 2014 to July 2015. And 52 healthy children who took physical examination in Department of Health Care were selected as control group. Developmental abilities of children were assessed by Developmental Screening Test(DST) at the age of 12 months,18months and 24 months old in high-risk infants and at the age of 24 months old in healthy children. Results The detection rate of language retardation was about 34.4% in high-risk infants at the age of 24 months old,significantly higher than that in control group(8.0%)(P＜0.05). The detection rate of full-term small-like infants was 63%,followed by 40% of the premature infants,and the ratio of male to female was 3.4∶1. No significant difference was found on the detection of dyskinesia and language retardation in high risk infants at the age of 12 months(P=0.191),and there was significant difference at the age of 18 and 24 months(P<0.05). Conclusions High-risk infants are still at high risk of language retardation,and the detection rate of language retardation caused by different factors is significantly different. Regular follow-up,monitoring and screening of language development are required for the early detection,early intervention in high-risk infants to improve the prognosis.
