Not applicable Interventional University of Oslo · NCT07085923

What this trial studies

This randomized, controlled 1:1 trial compares a structured 6‑month multidisciplinary lifestyle program (professional dietary counselling plus supervised moderate‑to‑high intensity exercise) with treatment as usual in Norwegian adults with severe mental illness. Primary outcomes include change in estimated cardiovascular disease risk, weight and body composition, and metabolic markers measured at baseline and six months. The study will also measure adherence and participant acceptability to determine feasibility within routine mental health services. Participants must have a BMI ≥27 kg/m2 and be on antipsychotic medication or lithium, while those with established cardiovascular disease, type 1 diabetes, pregnancy, inability to exercise, or initiating certain cardiometabolic drugs during the intervention are excluded.

Who should consider this trial

Good fit: Adults in Norway with schizophrenia‑spectrum disorders or bipolar I disorder who are currently taking antipsychotic medication or lithium and have a BMI of 27 kg/m2 or higher, who can provide informed consent and participate in exercise.

Not a fit: People with established cardiovascular disease, type 1 diabetes, pregnancy, inability to exercise, heavy alcohol use above study limits, or those who must start GLP‑1 agonists, antihypertensives, antidiabetics, or lipid‑lowering drugs during the study are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the program could lower estimated cardiovascular risk and improve weight, metabolic health, and daily lifestyle habits for people with severe mental illness.

How similar studies have performed: Previous trials in severe mental illness have produced mixed results, though programs that combine professional dietary counselling with moderate‑to‑high intensity exercise have shown the most promising effects.
