Improving physical health of patients with severe mental disorders: a critical review of lifestyle psychosocial interventions

Introduction: People with severe mental disorders have a mortality rate that is more than two times higher than the general population, with at least a decade of potential years of life lost. People with mental disorders have a significantly higher risk of obesity, hyperglycemia and metabolic syndrome, which are related to modifiable risk factors, such as heavy smoking, poor physical activities, and inappropriate unhealthy diet, which can be improved through lifestyle changes. Areas covered: Lifestyle behaviours are amenable to change through the adoption of specific psychosocial interventions, and several approaches have been promoted. In the present review, the authors aim to: 1) critically analyze studies involving multimodal lifestyle interventions; 2) discuss the way forward to integrate these interventions in clinical routine care. Expert commentary: The psychoeducational approaches developed for the improvement of healthy lifestyle behaviours differ for several aspects: 1) the format (individual vs. group); 2) the setting (outpatient vs. inpatient vs. home-based); 3) the professional characteristics of the staff running the intervention (psychiatrists or nurses or dietitians or psychologists); 4) the active ingredients of the intervention (education only or inclusion of motivational interview or of problem solving); 5) the duration of treatment (ranging from 3 months to 2 years).
