Background : Hearing holds a very important role for children. Noise exposure that exceeds the threshold for a long time may increase the risk of cochlear dysfunction in premature babies that could lead to hearing loss.
Material : This study was a case control study, from May to December 2017 at the Neonatal Intensive Care Unit (NICU) Wahidin Sudirohusodo Hospital. There was 63 subjects of premature babies with gestation age of 32 to 36 weeks that meet the criteria of inclusion and exclusion. They were then had Otoacustic Emmission examination. Subjects were divided into 2 groups with cochlear dysfunction and without cochlear dysfunction. Both group were divided into 2 groups with long exposure to noise more than or equal to 12 days and less than 12 days. Data were analyzed with SPSS-17, using chi square test analysis.
Results : We found 52.4% of premature babies experienced cochlear dysfunction. The result of multiple logistic regression analysis showed that prolonged noise exposure ?12 days was an independent risk factor for cochlear dysfunction, p value = 0.001 (p <0.05) in premature babies treated in Neonatal Intensive care unit. From analysis of noise exposure using ROC curve showed cut off point of ? 11 days with area under ROC curve 0.761, with 78.8% sensitivity, 73.3% specificity, and OR 10.204 with CI 95% 3.19-32.25.
Conclusions : Length of noise exposure over 11 days in premature babies is associated with cochlear dysfunction. Prolonged noise exposure is a risk factor for cochlear dysfunction in premature babies.
