Chris Dickens,Professor of Psychological MedicineUniversity of Exeter Medical School
STEPWISE project• Randomised controlled trial (how effective?)
• Lifestyle intervention based on DESMOND intervention
– For people with schizophrenia, schizo-affective disorder, first onset psychosis
• Funded by the NIHR. Hosted by University of Sheffield Clinical Trials Research Unit
• Chief Investigator, Richard IG Holt, Professor in Diabetes & Endocrinology, University of Southampton
• Local Principal Investigator:– Cornwall, Richard Laugharne, – Devon, Chris Dickens– Somerset, Andy Harewood

Schizophrenia• A long-term mental health condition
– (severe and enduring mental illness)
• Range of different symptoms, including: – Hallucinations
• hearing or seeing things that do not exist – Delusions
• unusual beliefs not based on reality that often contradict the evidence
– Muddled thoughts based on hallucinations or delusions– Changes in behaviour
• Affect 1 in every 100 people
• Range of treatment options, but commonly involves antipsychotic medication 3
Schizo-affective disorder• A long-term mental health condition (severe enduring
mental illness)
• Affects about 1 person in every 300
• Shares many of the feature of schizophrenia
• In addition, prominent disturbances of mood are a feature
• Range of treatment options including:
– Antipsychotics
– Antidepressants
– Mood stabilising medication

Physical Consequences of Severe Mental Illness
• Mortality increased 2.5-3x compared to general population
• Life expectancy is reduced by 10-20 years
• 75% of patients die from natural causes
– 33-60% die from CVD
Brown et al Br J Psychiatry. 2010 Feb;196(2):116-21 Osby Arch Gen Psychiatry. 2001 Sep;58(9):844-50
Causes of increased mortality
• Obesity is a risk factor for vascular disease
– Obesity v common in people with schizophrenia
– Approx 40-50% are obese compared to 20 to 30% in general population
• Causes of obesity in schizophrenia are complex
– Antipsychotic medication is linked to obesity
– Effects of antipsychotics on weight are very quick with majority of effect happening in first 3 months
NICE quality standard Feb 2015:Psychosis and schizophrenia in
adults• Quality statement 6:
– Evidence of local arrangements that adults with psychosis or schizophrenia have specific comprehensive physical health assessments
• Within 3 months of first starting treatment• 12 monthly thereafter
NICE quality standard Feb 2015:Psychosis and schizophrenia in
adults• Quality statement 7:
– Evidence of local arrangements that adults with psychosis or schizophrenia are offered combined healthy eating and physical activity programmes, and help to stop smoking
• Proportion who receive combined healthy eating and physical activity programmes in past 12 months
• Proportion of smokers who receive help to stop smoking within the past 12 months
Current research evidence
• We know that weight loss interventions are effective in people with schizophrenia,
• However
– Most studies are less than 3-6 months in duration
– Few studies in first episode psychosis
– No long term follow-up

STEPWISE: STructured lifestyle Education for People WIth SchizophrEnia • 4 year project funded by HTA aiming to:
– In people with schizophrenia, schizoaffective disorder or first episode psychosis
– Evaluate the extent to which a structured lifestyle education programme delivered t, can support weight loss
10
STEPWISE objectives• Adaptation of DESMOND intervention
– to make it more appropriate for and acceptable for mental health services
– to provide a greater focus on weight loss
• Undertake a multicentre randomised controlled trial to evaluate clinical and cost effectiveness of lifestyle intervention

Recruiting centres
12
STEPWISE Intervention• Structured education programme
• Delivered by two trained facilitators
• 4 x 2.5 hour (weekly) sessions – including lunch and breaks
– Focuses on diet and physical activity
• ‘support contact’ (1:1 personalised 10 min conversation) provided approx. every 2 weeks
• ‘booster’ (group) sessions at month 4, 7 and 10 (post-randomisation
13
Participant characteristics• Age ≥18 years old with no upper age limit
• A diagnosis of a schizophrenia or schizoaffective disorder
• Treatment with an antipsychotic for >1 month
• Body mass index ≥25 kg/m2 or concern about weight gain since treatment initiation
• Weight at 1 year after entry to the trial14
Numbers involved
• 412 participants (206 per arm)
– 40-50 participants per centre
– 20-25 of whom will receive the intervention in 3 or 4 groups
• Powered for a 5% difference in body weight at 12 months allowing for a 20% drop-out
