Abstract：Objective To investigate the delayed incidence of hearing loss and related risk factors of children.Method 10 225 newborn children 2～3 years old from December,2010 to December,2012 were researched.According to the American Association of Infant Hearing (JCIH) 2007 recommending delayed hearing loss risk factors,they were grouped into 9944 cases of normal group(without risk factors),and 281 cases of high-risk groups (with high risk factors).Through the use of child audiometer hearing screening,those who did not pass the screening had referrals for medical and audiological evaluation.Results Among 10 225 cases of screening subjects,543 children did not pass preliminary screening,and 279 children did not pass the second screening.230 children referred for audiological and medical evaluations.106 children were diagnosed with normal hearing,105 cases diagnosed as suffering from a variety of middle ear disease, and 19 children were eventually diagnosed with late-onset hearing loss.In delayed diagnosis of hearing loss,there were 11 cases in normal group,and the rate was 0.1%;there were 8 cases in high-risk group,and the rate was 2.8%.Statistical differences between two sets of data were highly significant.Conclusion Children with delayed incidence of hearing loss are much higher than having risk factors children having no risk factors.Among children 2～3 years old having passed newborn hearing screening,there is no obvious symptom of a certain percentage of tardive hearing loss.Only children with risk factors for hearing delayed follow-up is not sufficient to find preschool hearing loss occuring.The implementation of the various stages of hearing screening in preschool children can have early detection of hearing loss.
