博士 / 國立高雄師範大學 / 特殊教育學系 / 104 / PURPOSE: The aim is to study effectiveness of questionnaires to enhance the detection of noise induced threshold shift (NITS) and to formulate odd ratios on the established risk factors in the young school children population.
SUBJECTS: In Tier 1 of the study, the prevalence of NITS was studied amongst 1005 3rd -9th graders, in which consist of active noisy Battle Array participants , recruited from schools in KaoHsiung City. While in Tier 2 of the study, both NITS Screening and High-Risk Group Questionnaires were collected in 1050 students and their audiometric status measured.
METHODS: Three types of NITS criteria were applied to define the subject students’ audiometric status, and statistical descriptions outlined. Chi-square performed to delineate the significant factors and then Odd ratio performed. The weighting of each factors was analysed with multivariate regression methods and outcomes described.
RESULTS: Prevalence of 2.19%, 18.33% and12.9% of NITS subjects found when Niskar, Lin and Henderson’s NITS criteria were applied in our study, respectively. The prevalence observed in our study was vastly different from the literature, i.e. 12.5% by Niskar et al. Frequent involvement in noisy activity had no effect on NITS prevalence. Analysis of both questionnaires yielded ten correlated factors that might improve the outcome on NITS survey. Higher grade boys who have problems in speech reception in noise, sound lateralization and loudness perception were running at a higher risk of NITS. Impaired auditory symptoms that often presented in adults, such as tinnitus and hyperacusis, were not observed in children.
CONCLUSION: In order to properly implement a hearing screening program, consensus on the NITS criteria must be made due to discrepancies in prevalence amongst different definitions. Pure tone audiometry is still the mainstay of method but screening questionnaire might help to highlight the at-risk group, who are make awared of their own hearing health. Regular hearing tests can be considered. Tests that reveal cochlear pathology, such as speech discrimination test, can be considered to improve early detection of NITS.
