The metabolic implications of long term cannabis use in patients with psychosis

Willingness to use smartphone apps for lifestyle management among patients with schizophrenia

Mobile technology is a popular intervention mode for patients with schizophrenia because of its accessibility and functionality. We examined patients' willingness to use smartphone apps for lifestyle management and its effect on self-reported lifestyle habits. Five hundred fifty-five inpatients from various mental health institutions participated. Willingness to use smartphone apps was associated with age, education, income, device type, and body mass index. Positive opinions on smartphone app use were significantly associated with willingness to use apps, which was significantly associated with dietary and living habits. Thus, improving willingness to use apps can help patients improve their lifestyle, potentially preventing relapse.

The dietary pattern of patients with schizophrenia: a systematic review

OBJECTIVE

People with schizophrenia show a high incidence of metabolic syndrome, which is associated with a high mortality from cardiovascular disease. The aetiology of the metabolic syndrome in schizophrenia is multi-factorial and may involve antipsychotic treatment, high levels of stress and unhealthy lifestyle, such as poor diet. As a poor diet can predispose to the development of metabolic abnormalities, the aims of this review are to clarify: 1) the dietary patterns of patients with schizophrenia, 2) the association of these dietary patterns with a worse metabolic profile, and 3) the possible factors influencing these dietary patterns.

METHODS

A search was conducted on Pubmed, The Cochrane Library, Scopus, Embase, Ovid, Psychoinfo and ISI web of Knowledge from 1950 to the 1st of November 2011. 783 articles were found through the investigation of such databases. After title, abstract or full-text reading and applying exclusion criteria we reviewed 31 studies on dietary patterns and their effects on metabolic parameters in schizophrenia.

RESULTS

Patients with schizophrenia have a poor diet, mainly characterized by a high intake of saturated fat and a low consumption of fibre and fruit. Such diet is more likely to increase the risk to develop metabolic abnormalities. Data about possible causes of poor diet in schizophrenia are still few and inconsistent.

CONCLUSION

Subjects with schizophrenia show a poor diet that partly accounts for their higher incidence of metabolic abnormalities. Further studies are needed to clarify the causes of poor diet and the role of dietary intervention to improve their physical health.
