Method: A cross-section study was used to investigate on vertigo among middle school students. Questionnaire ,ear examination and auditory tests were carried out by the staff who received special training. Multiple Logistic regression models were used to analyze the relative influential factors about vertigo.
Result: There were 1567 middle school students who underwent a complete investigation. The participants comprised 793 males (50.6%) and 774 females (49.4%). The overall prevalence of vertigo was 5.6%. No significant difference of the prevalence was found between males (4.7%) and females (6.5%) (P > 0.05). The use of MP3 or MP4, insomnia and history of middle ear infections or ototoxic drugs ingestion were the main risk factors for vertigo (odds ratio: 2.837, 5.582, 2.808 and 1.695, respectively).
