The objective of the study was to determine the point prevalence of tardive dyskinesia (TD) in Chinese inpatients with chronic schizophrenia and its association with sociodemographic, clinical and treatment variables and other movement disorders. A cross-sectional assessment of a randomly selected cohort of inpatients (n=225; mean age=42+/-7 years) with DSM-IV schizophrenia was employed using standard rating instruments for TD and other drug-induced movement disorders, in addition to catatonia, and psychotic, negative, depressive and obsessive-compulsive symptoms. Using Schooler and Kane's criteria, 15 subjects (6.7%) had TD. Patients with TD were significantly older and significantly fewer of them were taking antiparkinsonian medication than subjects without TD. There was no significant difference between the TD and non-TD groups with respect to other demographic, clinical and treatment variables including sex, age of onset, length of contact with psychiatric services, current antipsychotic dosage, negative symptoms, catatonia and parkinsonism. The results confirmed the low prevalence of TD in patients with chronic schizophrenia compared to those found in Caucasian patients. The study has also replicated the association of TD in Chinese schizophrenia patients with older age but failed to demonstrate any association between TD and other demographic or clinical characteristics including catatonia.
