Objective: This study surveyed the prescribing patterns of antipsychotic medications in Asian older schizophrenia patients with extrapyramidal side effects (EPS) during the period between 2001 and 2009. Method: Information on 848 hospitalized patients with schizophrenia aged 60 or older was extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study (2001 – 2009). Data from those patients with reported EPS from 8 Asian countries and territories including China, Hong Kong, Japan, Korea, Singapore, Taiwan, India and Malaysia were analyzed. The cross-sectional data of sociodemographic and clinical characteristics and antipsychotic prescriptions were collected using a standardized protocol and data collection procedure. Results: Of the 309/848 (36%) patients suffering from EPS, 210 patients (210/309; 68.0%) received at least one type of first generation antipsychotic (FGA), and 99 (99/309; 32.0%) received second generation antipsychotics (SGAs) only. Of SGAs prescribed in patients with EPS, risperidone was the most commonly used (100/309; 32.4%) followed by olanzapine (33/309; 10.7%) and quetiapine (25/309; 8.1%). Conclusions: FGAs were frequently used in Asian older schizophrenia patients with EPS. Considering the potential adverse effects of FGAs on existing EPS, the reasons for the frequent use of FGAs need to be urgently identified.Correspondence to:

Objective: This study examined the proportion of overweight in schizophrenia inpatients in selected Asian countries and territories and its independent demographic and clinical correlates. Method: Data on 1,534 hospitalized schizophrenia patients in 9 Asian countries and territories were collected by a review of medical files supplemented by a clinical interview during a 1-month period. Patients’ sociodemographic and clinical characteristics, prescriptions of psychotropic drugs, and Body Mass Index (BMI) were recorded using a standardized protocol and data collection procedure. For analyzes, BMI ≥ 25 kg/m2 was defined as overweight. Results: The proportion of overweight was 35.8% (549/1,534) in the entire sample, with 39.7% (224/564) in females and 33.5% (325/970) in males (p = 0.01) and with wide inter-country variations. Multiple logistic regression analysis revealed that after controlling for study sites, overweight was independently associated with more frequent use of mood stabilizers (p < 0.001, odds ration (OR) = 1.4, 95% confidence interval (CI) = 1.1 – 1.8) and longer length of illness (p < 0.001, OR = 1.6, 95% CI = 1.2 – 2.1) but was less likely found in male patients (p = 0.003, OR = 0.7, 95% CI = 0.5 – 0.8). Conclusions: The prevalence of overweight Asian schizophrenia patients is significantly lower than the reported figures among their Western counterparts. There is considerable variation in prevalence of overweight schizophrenia patients within Asian countries and territories.Correspondence to:
