Nutrition and exercise review reports physical health gains in severe mental illness
Specialist-delivered programs improved selected physical health measurements, although missing comparison details and ambiguous reporting limit interpretation of the abstract.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Pooled results favored combined specialist-delivered nutrition and exercise programs for body mass index and waist circumference in people with severe mental illness. Nutrition-only studies also reported lower systolic blood pressure. These are physical health measures; the abstract does not establish improvements in psychiatric symptoms or sustained reductions in cardiovascular illness.
The exercise-only result is worded ambiguously, so its meaning cannot be resolved from the abstract. Comparison conditions, measurement units for the reported differences and exact follow-up periods are also missing.
Who delivered the programs
Eligible interventions involved a dietitian, nutritionist or exercise professional. The review considered combined programs as well as nutrition and exercise separately, so the findings concern specialist-delivered services for this particular clinical population.
Why study design matters
The review included randomized and nonrandomized controlled studies. Its findings should therefore not be read as though every program used the same study design. The abstract does not explain how that distinction affected the pooled estimates.
