The aim of this study was to assess the predictive utility of body mass index (BMI) for MetS among patients with schizophrenia in Japan.Methods: In total, 8468 patients (4705 males, 3763 females) with schizophrenia or schizoaffective disorders based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), or the International Classification of Diseases, tenth revision (ICD-10), were assessed for MetS using the criteria of the National Cholesterol Education Program Adult Treatment Panel III (ATP III-A). We applied a stratum-specific likelihood ratio (SSLR) analysis, which is independent of the prevalence of the target disease.Results: The mean (± standard deviation) age of these patients was 57.4 ± 13.5 years. The prevalence of MetS was 20.4%. Among males, the SSLRs predicting MetS were 0.03 (95% CI 0.02– 0.06), 0.54 (95% CI 0.48– 0.60), 2.77 (95% CI 2.44– 3.14) and 8.75 (95% CI 7.40– 10.36) for BMI < 20 kg/m2, 20 kg/m2 ≤ BMI < 25 kg/m2, 25 kg/m2≤ BMI < 28 kg/m2, and 28 kg/m2≤BMI, respectively. For females, the SSLRs predicting MetS were 0.08 (95% CI 0.05– 0.12), 0.73 (95% CI 0.66– 0.82), 2.50 (95% CI 2.16– 2.90) and 4.83 (95% CI 4.12– 5.67) for the same BMI categories, respectively.Conclusion: The predictive utility of BMI is confirmed, and BMI has more predictive value in males than in females. Patients with a BMI of 28 kg/m2 or greater had a significantly higher SSLR than those with a BMI less than 28 kg/m2.Keywords: body mass index, metabolic syndrome, schizoaffective disorder, schizophrenia |
