mental illness, weight loss, SMI
Morbidity and mortality rates of people with severe mental illness (SMI) are significantly higher than in the general population, with an estimated life expectancy reduction of 10 to 20 years,People with SMI engage less in physical activity, are more sedentary, have a higher calorific intake with excessive fats and sugars, and are more likely to smoke than the general population.We evaluated the effectiveness of a modified version of the Strategies to Reduce Injuries and Develop confidence in Elders (STRIDE) intervention, a group-based lifestyle intervention for people with SMI, in an outpatient treatment setting compared with treatment as usual (TAU). The intervention is based on the STRIDE weight loss and lifestyle intervention for individuals taking antipsychotic medications.
