[Hearing screening in high risk newborns and research of high risk factors of hearing loss in newborns].
OBJECTIVE
To identify the newborns who should receive hearing evaluation by hearing screening in high risk newborns; to find and confirm the high risk factors of hearing disorders in high risk newborns.


METHODS
The first screening was performed by DPOAE. Newborns did not passed the first screening undertook second screening using DPOAE + ABR. and newborns did not passed the second screening received hearing evaluation. High risk factors of hearing loss were found by Logistic regression analysis.


RESULTS
Three hundred and twenty-seven cases were screened. The positive ratio in first screening was 37.0%. The positive ratio in second screening was 11.0%. Ten cases were diagnosed as hearing loss and the incidence of hearing loss was 3.39%. High risk factors of hearing loss were asphyxiation, very low born weight (<1,500 g) and head and neck abnormality.


CONCLUSIONS
(1) DPOAE combined with ABR is credible and feasible in hearing screening of high risk newborns. (2) High risk factors of hearing loss were asphyxiation, very low born weight (<1,500 g) and head and neck abnormality in this study.
