Study Finds that Lifestyle Changes Can Lead to Weight Loss for People with SMI

For people with serious mental illness (SMI) the risk for being overweight or obese is significant. Four out of five people with SMI are overweight or obese in the United States. According to the Centers for Disease Control and Prevention (CDC), being overweight or obese can increase your risk for coronary heart disease, type 2 diabetes, some cancers, hypertension, dyslipidemia, stroke, and other health conditions. A recent study, published in the New England Journal of Medicine, shows that tailored lifestyle programs for people with serious mental health conditions can be effective in achieving healthy weight loss.  

The study consisted of 291 participants from 10 outpatient psychiatric rehabilitation programs that were randomly assigned to an intervention group or control group. The study found that the intervention group that received regular weekly group exercise classes and individual/group weight management classes had significant weight loss compared to the control group that had basic information on nutrition and exercise at the beginning of the study.

After 18 months the participants in the intervention group:

  • on average, lost 7 pounds more than the control group.
  • 38% lost 5% or more of their initial weight, as compared to 23% for the control group.
  •  nearly 1 in 5 participants lost 10% or more of their initial weight, as compared to 1 in 14 participants in the control group.

The study also found that the participants from the intervention group who were taking certain psychotropic medications known to cause weight gain still had significant weight loss as well. This study shows that when effective resources are provided, people with SMI can implement healthy lifestyle changes with good results, despite the many challenges that they face.
