Abstract: Objective To compare the differences of vestibular function among the pre-diabetic patients and the controls and to analysis the characteristics and risk factors of vestibular dysfunction in pre-diabetic patients. Methods All participants underwent oral glucose tolerance test. Sixty-two pre-diabetic patients were enrolled with 44 age-and sex-matched controls. Weight, height, and other general information are collected in all subjects. Laboratory tests and vestibular caloric test were carried out. Slow phase velocity was collected. In pre-diabetic patients, the risk factors associated with vestibular dysfunction were analyzed. Results There were 44 cases with vestibular dysfunction in pre-diabetic patients, while 17 cases in the controls, with the statistically significant difference (P=0.001). Compared with the controls, slow phase velocity decreased in both eyes in the pre-diabetic patients, with the statistically significant difference (P=0.026 for the right eyes and P=0.016 for the left eyes). Logistic regression analysis showed that as age and glycosylated hemoglobin A1c (HbA1c) increased, the pre-diabetic patients had an increased risk of vestibular dysfunction (age P=0.013, HbA1c P=0.040). Conclusion The incidence of vestibular dysfunction is increased in the pre-diabetic patients. Age and HbA1c might be risk factors associated with vestibular dysfunction in the pre-diabetic patients.
