Lifestyle in patients with severe mental disorders: a new target for psychosocial interventions?

Introduction. Patients with severe mental disorders (namely schizophrenia, major depression and bipolar disorder) have a reduced life expectancy of at least 10 to 25 years compared with the general population. This mortality gap is due to the higher prevalence of comorbid physical disorders (such as diabetes, hypertension and cardiovascular diseases) in these patients compared to the general population. Factors contributing to the mortality gap include lack of access to primary care services, severity of clinical symptoms, internalized stigma and discrimination by healthcare professionals, pharmacological treatments and unhealthy lifestyle behaviours. Several international studies have highlighted the high prevalence of unhealthy lifestyle behaviours in patients with severe mental disorders, but a few data are available from Italian real-world settings. Aim. The present study aims to: 1) describe the lifestyle behaviours adopted by a sample of real-world patients affected by severe mental disorders; 2) identify differences in lifestyle behaviours according to diagnostic category. Materials. The final sample consisted of 402 patients, mainly female (57%), with a mean age of 45.8 +/- 11.8 years. 35% of them suffers from moderate obesity and 40% of them is affected by hyperinsulinemia, hypercolestereloemia and hypertrygliceridemia. 70% of patients has sedentary behaviours. Moderate to severe nicotine dependence is reported by 42% of patients. Patients with bipolar disorders are more frequently smokers compared to other patients. No significant differences in lifestyle behaviours have been found among the three diagnostic groups. Results and conclusions. Our data confirm that patients with severe mental disorders adopt unhealthy lifestyle behaviours, regardless their diagnosis. New psychosocial interventions, including motivational and psychoeducational components and targeting lifestyle behaviours, should be developed and disseminated in order to reduce the mortality gap.
