In patients with severe mental disorders, motivation to follow a healthy diet and lifestyle might be low. A diet rich in fruits and vegetables may improve metabolic syndrome, cardiovascular health and mental health. This randomised community-based clinical trial included seventy-four patients with severe mental disorders out of which 37.8% of the participants had schizophrenia or related disorders, 29.7% had bipolar disorder, 25.7% had depressive disorder, 4.1% had a personality disorder, and 2.7% had obsessive-compulsive disorder. The intervention group followed a four-week food education programme (DIETMENT) aimed at promoting fruit and vegetable consumption. A five-month post-intervention analysis showed no increase in participants diagnosed with metabolic syndrome in the intervention group, but an increase in participants diagnosed with metabolic syndrome in the control group. There was a significant reduction in the glomerular filtrate rate in the intervention group. In patients with severe mental disorders, more studies should be conducted to examine the health-promoting effects of adding more fruits and vegetables to the diet. Health professionals can use the results of this study to understand how fruits and vegetables contribute to reducing metabolic syndrome and heart disease risk.
Abstract
OBJECTIVES The aim of this study is to determine the metabolic impact of a nutrition education program on metabolic parameters and the presence of metabolic syndrome (MetS). RESULTS Seventy-four patients were included (mean age, 48.7 years [Standard deviation, SD: 10.8], 55.4% men). The diagnoses of SMD were 37.8% schizophrenia and related disorders; 29.7% bipolar disorder; 25.7% depressive disorder; 4.1% personality disorders; and 2.7% obsessive compulsive disorders. Thirty-seven individuals were distributed in both the intervention group (IG) and the control group (CG). In the IG the presence of MetS was 56.3% and in the CG 46.7%, with no statistically significant difference (p = 0.309). At the end of the study, glomerular filtrate decreased in the IG, body mass index and abdominal perimeter increased in both groups, and there were no changes in metabolic parameters between the groups. Between the baseline and the end of the study, there was no increase in the number of patients diagnosed with MetS (14 at both points); and in the CG the increase was from 8 to 12 (p = 0.005). An intervention based on fruit and vegetable intake could prevent progression to MetS in individuals with SMD, decreasing the likelihood of cardiovascular disease. Trial registration The trial was retrospectively registered on International Standard Randomised Controlled Trial Number (ISRCTN) Register on 11 March 2022 (ISRCTN12024347).

Plain language summary
People with severe mental disorders are prone to follow poor dietary choices. Seventy-four participants with severe mental disorders were enrolled in this community-based randomised controlled trial to evaluate changes in fruit and vegetable consumption, as well as changes in their motivation to consume five portions of fruits and vegetables a day. The participants with severe mental disorders in the intervention group participated in a food education programme (DIETMENT) based on the stages of change model to promote the consumption of fruit and vegetables prior to the evaluation. The intervention group showed an increase of 23% in fruit and vegetable consumption when compared to the control group, even though the difference was not statistically significant. The food education programme based on the stages of change model increased motivation, awareness and disposition in participants in the intervention group. In order to identify appropriate strategies for increasing fruit and vegetable consumption in patients with severe mental disorders, there is a need to conduct more robust studies. The results of this study may, however, provide healthcare professionals with a greater understanding of how a food education programme based on the stages of change framework encourages patients with severe mental disorders to consume fruit and vegetables.
Abstract
Despite growing evidence of the benefits of adequate intake of fruit and vegetables (F&V) and the recommendation to consume five servings daily, the adoption of these habits is poor among people with severe mental disorder (SMD). The main aim of the present study is to determine changes in the intake of F&V and motivation to do so among people with SMDs after participating in a food education programme. A community-based randomized controlled trial was conducted in Spain, with the intervention group (IG) participating in a food education programme based on the stages of change model to promote consumption of F&V and the control group (CG) receiving three informative sessions on basic healthy eating. The main outcomes were related to the intake of F&V and stages of change. Data collection was performed at baseline, post intervention, and 12-month follow-up. Seventy-four participants enrolled in the study and sixty completed the 12-month follow-up. An increase in motivation towards the intake of F&V was observed in the IG but not in the CG (McNemar's test p = 0.016, p = 0.625). No significant difference was observed for the intake of fruit, vegetables, or F&V. Basing food education strategies on the stages of change model shows positive results, increasing the awareness and disposition of people with SMD towards the intake of F&V. More research is needed to identify the most appropriate eating intervention to increase the intake of F&V.

Plain language summary
People with schizophrenia are often overweight. Losing weight and being more active can reduce the risk of type 2 diabetes mellitus, heart disease and dying early. The NHS recommends offering a weight loss programme; however, mental health care providers do not know the best way to do this. This study assessed whether an education programme to help people with psychosis to lose weight would be better than the usual care provided by the NHS. A total of 414 people took part. Half were selected at random to attend an education programme run by trained facilitators. The other half received their usual health care. The researchers found no difference in weight between the two groups, at either 3 months or 12 months. They also found that the programme did not provide good value for money. In interviews, service users said that they liked the education programme and that it helped them to eat healthily and lose weight. However, there was no change in their diet and activity levels in either group. Unfortunately, although some people benefited, the programme did not work for most people. The researchers concluded that they need to look for better ways to help people with psychosis to lose weight.
Abstract
BACKGROUND Obesity is twice as common in people with schizophrenia as in the general population. The National Institute for Health and Care Excellence guidance recommends that people with psychosis or schizophrenia, especially those taking antipsychotics, be offered a healthy eating and physical activity programme by their mental health care provider. There is insufficient evidence to inform how these lifestyle services should be commissioned. OBJECTIVES To develop a lifestyle intervention for people with first episode psychosis or schizophrenia and to evaluate its clinical effectiveness, cost-effectiveness, delivery and acceptability. DESIGN A two-arm, analyst-blind, parallel-group, randomised controlled trial, with a 1 : 1 allocation ratio, using web-based randomisation; a mixed-methods process evaluation, including qualitative case study methods and logic modelling; and a cost-utility analysis. SETTING Ten community mental health trusts in England. PARTICIPANTS People with first episode psychosis, schizophrenia or schizoaffective disorder. INTERVENTIONS Intervention group: (1) four 2.5-hour group-based structured lifestyle self-management education sessions, 1 week apart; (2) multimodal fortnightly support contacts; (3) three 2.5-hour group booster sessions at 3-monthly intervals, post core sessions. Control group: usual care assessed through a longitudinal survey. All participants received standard written lifestyle information. MAIN OUTCOME MEASURES The primary outcome was change in weight (kg) at 12 months post randomisation. The key secondary outcomes measured at 3 and 12 months included self-reported nutrition (measured with the Dietary Instrument for Nutrition Education questionnaire), objectively measured physical activity measured by accelerometry [GENEActiv (Activinsights, Kimbolton, UK)], biomedical measures, adverse events, patient-reported outcome measures and a health economic assessment. RESULTS The trial recruited 414 participants (intervention arm: 208 participants; usual care: 206 participants) between 10 March 2015 and 31 March 2016. A total of 341 participants (81.6%) completed the trial. A total of 412 participants were analysed. After 12 months, weight change did not differ between the groups (mean difference 0.0 kg, 95% confidence interval -1.59 to 1.67 kg; p = 0.964); physical activity, dietary intake and biochemical measures were unchanged. Glycated haemoglobin, fasting glucose and lipid profile were unchanged by the intervention. Quality of life, psychiatric symptoms and illness perception did not change during the trial. There were three deaths, but none was related to the intervention. Most adverse events were expected and related to the psychiatric illness. The process evaluation showed that the intervention was acceptable, with participants valuing the opportunity to interact with others facing similar challenges. Session feedback indicated that 87.2% of participants agreed that the sessions had met their needs. Some indicated the desire for more ongoing support. Professionals felt that the intervention was under-resourced and questioned the long-term sustainability within current NHS settings. Professionals would have preferred greater access to participants' behaviour data to tailor the intervention better. The incremental cost-effectiveness ratio from the health-care perspective is £246,921 per quality-adjusted life-year (QALY) gained and the incremental cost-effectiveness ratio from the societal perspective is £367,543 per QALY gained. CONCLUSIONS Despite the challenges of undertaking clinical research in this population, the trial successfully recruited and retained participants, indicating a high level of interest in weight management interventions; however, the STEPWISE intervention was neither clinically effective nor cost-effective. Further research will be required to define how overweight and obesity in people with schizophrenia should be managed. The trial results suggest that lifestyle programmes for people with schizophrenia may need greater resourcing than for other populations, and interventions that have been shown to be effective in other populations, such as people with diabetes mellitus, are not necessarily effective in people with schizophrenia.
