Review Urges Greater Exercise Integration in Schizophrenia, SMI Care
Key Clinical Summary
- Adults with severe mental illness experience a 10–20-year reduction in life expectancy, largely due to cardiometabolic disease and modifiable lifestyle factors such as low physical activity.
- Evidence summarized in a JAMA Psychiatry review shows structured physical activity improves depressive and psychotic symptoms, cognition, quality of life, and cardiometabolic health.
- Researchers recommend integrating exercise into psychiatric care using a clinical framework such as the 5A model (Ask, Assess, Advise, Assist, Arrange) to reduce sedentary behavior and support patient engagement.
The integration of physical activity into routine psychiatric care could significantly improve outcomes for people with severe mental illness (SMI), including schizophrenia, according to a narrative review published in JAMA Psychiatry. The authors synthesize existing evidence showing that exercise and reduced sedentary behavior improve both psychiatric and physical health outcomes but remain underutilized in clinical psychiatric practice.
Study Findings
Adults living with SMI face a 10- to 20-year reduction in life expectancy, primarily driven by cardiometabolic diseases, according to Brendon Stubbs, PhD, Institute of Psychiatry, Psychology and Neuroscience at King’s College London, and co-authors. Low levels of physical activity and prolonged sedentary behavior are identified as key modifiable risk factors contributing to this mortality gap.
The authors report that individuals with SMI are among the most physically inactive populations, frequently spending more than 10 hours per day sedentary and rarely meeting recommended physical activity guidelines. Such inactivity is associated with adverse neuroinflammatory, neuroendocrine, and cardiometabolic processes that can worsen psychiatric symptoms and overall health outcomes.
Evidence from recent meta-analyses cited in the review indicates that structured physical activity—particularly exercise programs—can produce moderate to large reductions in depressive and psychotic symptoms. Exercise interventions also demonstrate improvements in cognitive function, quality of life, and cardiometabolic health among people with severe mental illness.
Sedentary behaviors also appear to influence mental health outcomes. The review notes that mentally passive sedentary activities, such as prolonged television viewing, are associated with poorer mental health. Conversely, physical activity performed during leisure time or active travel may yield greater mental health benefits.
To support clinical implementation, the authors recommend that psychiatric clinicians adopt structured approaches such as the 5A framework—Ask, Assess, Advise, Assist, and Arrange—to screen patients for physical activity levels, provide tailored recommendations, support goal setting, and coordinate follow-up or community referrals.
Clinical Implications
The findings highlight an opportunity to address both psychiatric symptoms and physical comorbidities through lifestyle interventions integrated directly into mental health care. Routine assessment of physical activity levels in psychiatric settings may allow clinicians to identify patients at risk and intervene earlier.
According to the review, physical activity interventions should be individualized, focusing on activities that align with patient preferences and physical capabilities to enhance adherence and sustainability. Exercise prescriptions may include strength training at least twice weekly, along with other forms of activity such as walking, cycling, or structured exercise programs.
Integrating physical activity into psychiatric care may also reduce sedentary behavior, which is increasingly recognized as an independent health risk. By embedding lifestyle interventions into routine psychiatric visits, clinicians may help narrow the life expectancy gap associated with severe mental illness while improving overall quality of life.
Expert Commentary
“Physical activity should be considered a core component of psychiatric care,” concluded Dr Stubbs and co-authors. The authors noted that systematically promoting physical activity and reducing sedentary behavior could improve psychiatric symptoms and physical health outcomes for individuals with severe mental illness.
