Metabolic Syndrome in a Population of In-Patients with Schizophrenia in the Western Siberia

Abstract

Background. The relevance of this work is due to the incomplete nature of existing studies on risk factors of metabolic syndrome (MS) in patients with schizophrenia. Aim: to study the MS prevalence in schizophrenia in-patients and their clinical, therapeutic and socio-demographic features. Patients and methods: 517 in-patients diagnosed with schizophrenia according to the ICD-10 criteria were examined. All patients underwent a structured clinical interview (SCID); measurement of waist circumference, blood pressure and assessment of biochemical parameters for verification of MS based on the criteria of the IDF (International Diabetes Fediration). An assessment of the severity of clinical and psychopathological symptoms was performed using the PANSS. Results: the prevalence of MS in in-patients with schizophrenia in the Western Siberia is similar to that reported in the literature. It was found that in-patients with schizophrenia and MS are characterized by a predominance of women and older age, as well as a large proportion of divorced, and a smaller proportion of never married. Women with MS were older, got longer duration of illness, and got later onset of disease than men with MS. The age of disease onset was significantly greater in patients with MS than in patients without MS. Atypical antipsychotics were more often used as the basic antipsychotic treatment in the group of patients with MS but this difference between the groups did not reach statistical significance. Conclusions: the main risk factors in patients with schizophrenia and MS coincide with risk factors of MS in general population. A later onset of the disease can act as an independent risk factor. The relationship and mutual influence of risk factors for the development of MS in patients with schizophrenia needs further study.
