To investigate the prevalence of temporomandibular disorders(TMD) symptoms, psychological distress and sleep quality in a population of Chinese university students, and discuss the relationship between psychological distress, sleep quality and TMD symptoms. A total of 898 stomatological university students from 5 Chinese universities(342 males and 556 females with a mean age of 20.5 years) were included in the study. Self-reported TMD symptoms using diagnostic criteria for temporomandibular disorders symptom questionnaire were collected. Depression, anxiety and stress scales-21(DASS-21) and Pittsburgh sleep quality index(PSQI) were used to measure psychological distress and sleep quality. 61.9% (556/898) of the students had TMD symptoms. The most common symptoms were pain and clicking of joint, with a prevalence of 42.3% (380/898) and 34.2% (307/898), respectively. The prevalence of depression, anxiety, stress and sleep quality among the students who had TMD symptoms was 33.5%(186/556), 63.1%(351/556), 29.5%(164/556) and 30.2%(243/556), respectively, which was significantly higher than those who had no TMD symptoms(24.3% [83/342], 48.5% [166/342], 21.6%[74/342] and 21.9%[75/342])(P<0.05). Stepwise logistic regression analysis demonstrated that anxiety (OR 1.57, 95%CI 1.14-2.15) and female(OR 1.57, 95%CI 1.19-2.08) were possible risk indicators for TMD symptoms(P<0.05). Chinese university students reported a high prevalence of TMD symptoms, which may have a correlation with psychological distress symptoms such as anxiety.
