新疆大学生颞下颌关节紊乱病相关因素的Logistic回归分析

Logistic regression analysis of temporomandibular disorders in young people in Xinjiang

目的探讨新疆大学生颞下颌关节紊乱病患病率及其相关的发病因素。方法对新疆医科大学812名在读医学生使用Helkimo指数进行分析颞下颌关节紊乱病的患病情况调查。相关因素进行Logistic回归分析。结果颞下颌关节紊乱病的患病率占39.50%。咬合关系中前牙深覆及反,不良习惯中的偏侧咀嚼,夜磨牙为主要危险因素,增加TMD患病的风险。结论错畸形与应力疲劳与颞下颌关节紊乱病的发生有关。

Objective To investigate the prevalence and of the temporomandibular disorders（ TMD） in young people in Xinjiang and to identify its possible clinical risk factors. Methods A sample of 812 medical students was randomly selected from Xinjiang Medical University. The prevalence of TMD was analyzed by Helkimo index,and the possible risk factors associated with the disease were identified by logistic regression analysis. Results The prevalence of TMD was 39. 50% in this population. Malocclusion,chewing-side preference and bruxism were the main risk factors which increased the possible occurrence of TMD. Conclusions Malocclusion and occlusal stress fatigue were related to the formation of temporomandibular disorders.
