Metabolic syndrome and health-related quality of life in patients with schizophrenia.

The association of metabolic syndrome (MetS) with health-related quality of life (HRQol) in schizophrenia is poorly documented. The relationship between MetS, HRQol and global functioning were examined. For this goal, 76 individuals with schizophrenia and schizoaffective disorder (DSM-IV criteria) were interviewed to obtain sociodemographic data, lifestyle habits, psychopathology (PANSS scale), global functioning (GAF scale), sef-reported quality of life (EQ-5D scale) and the anthropometric measures and blood test results. MetS was defined by the NCEP (2005) criteria. The prevalence of MetS was 36.8%. MetS was directly associated with personal background of dyslipidaemia and diabetes mellitus. Subjects with MetS had greater weight, BMI, waist, blood pressure, triglycerides, fasting glucose and a lower HDL-cholesterol. The MetS is also associated with age, inactive employment status and better self-care. The EQ VAS (visual analogue scale) of EQ-5D shows that subjects with MetS who practice physical activity indicates a better subjctive perception of health, which remarks the necessity of improving healthy lifestyle and an interdisciplinary treatment of the MetS. There is no association between global functioning and HRQol. This is the first study which investigates the relationship between MetS, HRQol and GAF in individuals with schizophrenia in the European context.
