2 Introduction A great deal of research has been done on physical health in schizophrenia which has shown that sufferers have higher rates of morbidity and mortality from cardiovascular and respiratory diseases, and a shorter life expectancy (Brown S et al, 1997; Brown S et al, 2000). A great deal of research has been done on physical health in schizophrenia which has shown that sufferers have higher rates of morbidity and mortality from cardiovascular and respiratory diseases, and a shorter life expectancy (Brown S et al, 1997; Brown S et al, 2000). People with schizophrenia tend to eat less fruit and vegetables, take less exercise, are more likely to smoke and have higher rates of obesity (Brown S et al, 1999; McCreadie R et al, 2003). People with schizophrenia tend to eat less fruit and vegetables, take less exercise, are more likely to smoke and have higher rates of obesity (Brown S et al, 1999; McCreadie R et al, 2003). To make matters worse many of the drugs used to treat schizophrenia are associated with weight gain and have been linked to obesity and type II diabetes (Russel J et al, 2001; Newcomer J, 2005). To make matters worse many of the drugs used to treat schizophrenia are associated with weight gain and have been linked to obesity and type II diabetes (Russel J et al, 2001; Newcomer J, 2005). When compared to people from low social class backgrounds in the general population, sufferers have been shown to have significantly less healthy lifestyles (Brown S et al, 1999; McCreadie R et al, 2003). When compared to people from low social class backgrounds in the general population, sufferers have been shown to have significantly less healthy lifestyles (Brown S et al, 1999; McCreadie R et al, 2003).

3 Method This is a qualitative study in which 7 people with schizophrenia were interviewed using semi-structured interviews about their lifestyle, including their diet and exercise and were encouraged to talk about the various factors which might influence their decisions and behaviour with respect to these. This is a qualitative study in which 7 people with schizophrenia were interviewed using semi-structured interviews about their lifestyle, including their diet and exercise and were encouraged to talk about the various factors which might influence their decisions and behaviour with respect to these. They were deemed to have had a stable mental state for at least the previous 1 month prior to interview and be living in the community. They were deemed to have had a stable mental state for at least the previous 1 month prior to interview and be living in the community. The subjects were selected using criterion based purposeful sampling (Patton, 2002). They were identified through discussion with their consultant, care coordinator and family if possible, and review of their medical notes. The subjects were selected using criterion based purposeful sampling (Patton, 2002). They were identified through discussion with their consultant, care coordinator and family if possible, and review of their medical notes. Those who also had a diagnosis of a comorbid affective illness, anxiety disorder, alcohol dependence or illicit drug dependence were excluded.

5 Method continued Thematic analysis was used to analyse the data which was coded into categories in order to identify common themes (Merriam, 2009). Thematic analysis was used to analyse the data which was coded into categories in order to identify common themes (Merriam, 2009). The analysis of transcribed interviews was carried out by 5 analysts made up of a GP, general nurse, psychiatric nurse, psychiatrist and a layperson with a legal background. The analysis of transcribed interviews was carried out by 5 analysts made up of a GP, general nurse, psychiatric nurse, psychiatrist and a layperson with a legal background. All 5 analysts were asked to read through the 7 transcripts in full, and were asked to pick out sentences they thought gave valuable or relevant information giving the line reference from the appropriate text, and give a reason or comment on why they thought that particular segment of text was significant.

6 Method continued The information provided by the analysts was sent as a feedback report to the primary investigator. The feedback reports from the analysts were then analysed in detail by the primary investigator with reference to the transcripts to identify common themes. The information provided by the analysts was sent as a feedback report to the primary investigator. The feedback reports from the analysts were then analysed in detail by the primary investigator with reference to the transcripts to identify common themes. The themes identified by the analysts were assigned colours which were used to code the data by highlighting the lines in the feedback reports where any given theme was found, and were then cross-referenced to identify those which appeared to be the most frequent and consistent across all subjects interviewed. ie common themes The themes identified by the analysts were assigned colours which were used to code the data by highlighting the lines in the feedback reports where any given theme was found, and were then cross-referenced to identify those which appeared to be the most frequent and consistent across all subjects interviewed. ie common themes

7 Results – Subjective Lack of Motivation Quote 1: I just cant get anything done. I cant get motivated to do anything like housework or even going walking outside, I dont want to do it sometimes. Quote 1: I just cant get anything done. I cant get motivated to do anything like housework or even going walking outside, I dont want to do it sometimes. Quote 2: The other thing thats stopping me from buying more food is lack of motivation. It takes you about an hour to cook and eat a meal doesnt it really. You know, something substantial like meat and 2 veg. It just gets too much. I like to just have things that are easy and simple even though it gets boring.

11 Discussion A meta-analysis of 11 RCTs found that adding SSRIs to antipsychotics did not reduce negative symptoms in people with schizophrenia- spectrum disorder (Sepehry AA et al, 2007). A meta-analysis of 11 RCTs found that adding SSRIs to antipsychotics did not reduce negative symptoms in people with schizophrenia- spectrum disorder (Sepehry AA et al, 2007). The efficacy of glutamatergic agents for negative symptoms has also been studied, and they have also generally been found to be ineffective (Buchanan R W et al, 2007) The efficacy of glutamatergic agents for negative symptoms has also been studied, and they have also generally been found to be ineffective (Buchanan R W et al, 2007) Research is ongoing in this area and psychosocial interventions may prove more useful than medication at tackling this syndrome of symptoms, for example some positive effects in reducing negative symptoms have been found with music therapy (Gold C et al, 2005). Research is ongoing in this area and psychosocial interventions may prove more useful than medication at tackling this syndrome of symptoms, for example some positive effects in reducing negative symptoms have been found with music therapy (Gold C et al, 2005). A recent meta-analysis of CBT for schizophrenia showed a significant beneficial effect on positive symptoms but in the group of methodologically adequate studies the effects on negative symptoms were not significant (Wykes T et al, 2008). A recent meta-analysis of CBT for schizophrenia showed a significant beneficial effect on positive symptoms but in the group of methodologically adequate studies the effects on negative symptoms were not significant (Wykes T et al, 2008).

12 Discussion continued Other studies have also shown a relationship between positive symptoms and impairment in quality of life (Mohamed S et al, 2008). Recently more emphasis has been placed on the use of psychosocial interventions to help reduce these symptoms, and there is a great deal of evidence that CBT especially is effective (Wykes T et al, 2008). Other studies have also shown a relationship between positive symptoms and impairment in quality of life (Mohamed S et al, 2008). Recently more emphasis has been placed on the use of psychosocial interventions to help reduce these symptoms, and there is a great deal of evidence that CBT especially is effective (Wykes T et al, 2008). Studies have shown that interventions which have included health promotion and education such as a nurse led well being programme (Ohlsen RI et al, 2005) and a GP led inpatient service (Welthagen E et al, 2004) can have significant beneficial effects in patients with a variety of mental disorders including schizophrenia.

13 Discussion continued The detrimental effect of weight gain (Allison DB et al, 2003) and metabolic syndrome (Meyer JM et al, 2005) on quality of life has been found in other studies. The detrimental effect of weight gain (Allison DB et al, 2003) and metabolic syndrome (Meyer JM et al, 2005) on quality of life has been found in other studies. An RCT in of patients with first psychotic episode schizophrenia found that metformin and lifestyle changes (psychoeducation, dietary changes and exercise) were effective in reducing antipsychotic induced weight gain in adults, especially when used together (Wu RR et al, 2008). An RCT in of patients with first psychotic episode schizophrenia found that metformin and lifestyle changes (psychoeducation, dietary changes and exercise) were effective in reducing antipsychotic induced weight gain in adults, especially when used together (Wu RR et al, 2008). A meta-analysis of non-pharmacological interventions (CBT, nutritional counselling and exercise) found that they were effective in managing weight gain related to antipsychotic use in people with schizophrenia spectrum disorders (Alvarez-Jimenez M et al, 2008). A meta-analysis of non-pharmacological interventions (CBT, nutritional counselling and exercise) found that they were effective in managing weight gain related to antipsychotic use in people with schizophrenia spectrum disorders (Alvarez-Jimenez M et al, 2008).

14 Implications The aim of this study was to improve our understanding of the possible causes of the unhealthy lifestyle choices of people with schizophrenia. These findings suggest that there are many factors at play which appear to make it more likely for people with a diagnosis of schizophrenia to make unhealthy choices rather than healthy ones. This emphasises the complexity of this illness which has multiple syndromes and also the less than ideal treatments we currently have at our disposal. It suggests that we need to take a holistic approach when considering the physical health of such patients and that health promotion and education must go hand in hand with rigorous physical health monitoring and careful prescribing.
