Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A lifestyle intervention including a combination of low grade physical activity and targeted dietary modification would be supported and monitored by the research team together with clients’ Mental Health case manager, clozapine coordinators, consumer volunteers, and/or their NDIS or Community managed organisation support worker. The lifestyle intervention will run for three months.

Dietary component
The dietary intervention will consist of an individualised dietary assessment using online the Australian Eating Survey (AES) which identifies key areas that require change. Intake from each of the food groups is subsequently used to calculate an individual's macronutrient and micronutrient intake.

At the end of the dietary assessment participants will be provided with feedback which will be delivered face to face by a dietician with three goals: a) reducing sweetened drinks, b) reduction in discretionary foods and snacks c) increase core food intake. These factors have been shown to be prevalent issues in this population group and will lead to a reduction in total energy intake.

Those in the control group will only be provided with this feedback and no other lifestyle intervention. They will continue to be case managed by the mental health service and receive ongoing psychiatric treatment for schizophrenia.

Those in the intervention group will receive the three individual sessions delivered face to face by either dietician or clinical psychologist, at baseline, 2 months and 3 months which come from Food Fix programs. The dietician has over 10 of experience in delivering dietary interventions as well as having experience in delivering the Food Fix Program. The clinical psychologist has over 10 years of experience in providing clinical and lifestyle interventions to people with mental health problems

The dietary sessions consist of:
Session 1 consists of provision of feedback from the online survey and development of dietary goals and encouraging the participant to make dietary changes.

Session 2 will occur at 2 months and will utilise motivational interview techniques to help the participant explore barriers to change and provide coping strategies to help the client overcome some of the barriers.

Session 3 last session will occur at 3 months, and will be used as a check in to see how the participant is traveling

Physical fitness component
The physical fitness will be assessed using a 6 minute walk test, which counts the number of times a person is able to walk between two witches’ hats. All participants will be assessed. The fitness test will be done by clinical psychologist who has over 10 years’ experience in physical fitness assessments and provision of lifestyle interventions.

Those in the intervention group will be encouraged to join a walking group which will be run from the community managed organisation by the support workers. The intervention will involve supervised walking groups, 40 minutes per day three times per week. As participants get fitter a 20 minutes supervised brisk walk or going up and down stairs, once a week, will be incorporated into the 40 minute walk. The walking groups will be delivered face to face under the supervision of two support workers.

Weekly support group sessions will be used to motivate clients, discuss any barriers and difficulties in adhering to the dietary and physical intervention. These sessions will occur straight after the walking group. These groups will be run by the clinical psychologist in collaboration with the support workers involved in the walking groups. The clinical psychologist has over 10 years of experience in providing clinical and lifestyle interventions to people with mental health problems. The support workers have at least 6 years of experience in support to people with mental health issues.

The intervention adherence will be assessed by keeping attendance log which will record the number of times participants attended the walking groups and number of dietary sessions attended. The records will be kept by the support worker involved in walking groups and dietician delivering the dietary intervention.

Statistical methods / analysis
Chi-square tests (for categorical variables) and analyses of variance (for continuous variables) were used to examine differences between groups for the demographic variables, diagnostic and blood profiles. In addition, community contacts and admissions were expressed as rates per year for the purposes of describing the data. Univariate and multivariate logistic regressions will be used to examine primary and secondary outcome.
