Severe mental illness is characterised by a 20-year mortality gap due to premature cardiometabolic disease. Dietary intake is an important and modifiable risk factor for cardiometabolic disease. Our prior work found that a 12-week intensive, individualised nutrition intervention improved dietary intake and, combined with a physical activity intervention, prevented antipsychotic-induced weight gain. This study reports the effects of a two-year Step-Down Program, following the 12-week intensive intervention. The Step-Down Program offered individualised dietetic consultations and practical group sessions. Energy intake, diet quality and discretionary food intake were measured by food frequency questionnaires in 67% of participants (n=12) who were still engaged at 2-years. Diet quality remained significantly higher at the two-year mark compared to baseline [mean change = 2.9, 95%CI 0.8 to 5.8, p <0.05]. This was predominantly driven by increased vegetable variety and amount [mean change = 3.1, 95%CI 1.6 to 4.6, p = 0.001]. Intake of discretionary food was 40% lower compared to baseline [mean change = -1,421kJ, 95%CI -3,226 to 384, p = 0.02]. These dietary improvements were associated with sustained weight [mean change = 1.3kg, 95%CI -4.0 to 6.6, p = 0.6] and waist-circumference [mean change = 0.1cm, 95%CI -4.9 to 5.1, p = 0.9] neutrality at 2-years. A nutrition intervention delivered during the first two years of antipsychotic medication treatment improves dietary intake and contributes to the attenuation of antipsychotic-induced weight-gain as part of a larger lifestyle program.
