The aim of this study was to evaluate the efficacy of a psychoeducational program (PEP) for weight control in patients who had experienced an increase of body weight during treatment with olanzapine.
Eligible patients were randomised to the PEP (Group 1) or to no intervention (Group 2) and continued on olanzapine. After 12 weeks, the PEP was also started in Group 2 and continued in Group 1, up to week 24. Body weight was measured every month. Other measures included quality of life, and change in plasma glucose and lipids levels.
Patients in Group 1 (n=15) had a mean weight loss of 3.6 kg at week 12 and 4.5 kg at week 24 (p<0.01 at both times, p<0.01 between groups at week 12), while those in Group 2 (n=18) had no changes at week 12 and a significant weight loss at week 24 (-3.6 kg from week 12, p<0.01). Changes of BMI paralleled those of body weight. Quality of life (Q-LES-Q-SF categorisation) and functioning (GAF) significantly improved in the total population at endpoint (p<0.01). No significant changes were observed in fasting glucose and lipid profile, while insulin levels significantly decreased from baseline to endpoint in both groups (p<0.05). HOMA index and hepatic insulin sensitivity improved, too.
Patients with increased BMI during treatment with olanzapine experienced significant weight and BMI loss following a structured psychoeducational program.
"Hence, health promotion interventions targeting PA and healthy eating should be integrated into the daily care of individuals with MD. The results of previous research suggested that weight loss following behavioural and/or psycho-educational programmes in MD patients is possible [10, 11]. Evidence on the effectiveness alone of such interventions is yet insufficient for policy making. "
[Show abstract][Hide abstract] ABSTRACT: Background
There is a higher prevalence of obesity in individuals with mental disorders compared to the general population. The results of several studies suggested that weight reduction in this population is possible following psycho-educational and/or behavioural weight management interventions. Evidence of the effectiveness alone is however inadequate for policy making. The aim of the current study was to evaluate the cost-effectiveness of a health promotion intervention targeting physical activity and healthy eating in individuals with mental disorders.
A Markov decision-analytic model using a public payer perspective was applied, projecting the one-year results of a 10-week intervention over a time horizon of 20 years, assuming a repeated yearly implementation of the programme. Scenario analysis was applied evaluating the effects on the results of alternative modelling assumptions. One-way sensitivity analysis was performed to assess the effects on the results of varying key input parameters.
An incremental cost-effectiveness ratio of 27,096€/quality-adjusted life years (QALY) in men, and 40,139€/QALY in women was found in the base case. Scenario analysis assuming an increase in health-related quality of life as a result of the body mass index decrease resulted in much better cost-effectiveness in both men (3,357€/QALY) and women (3,766€/QALY). The uncertainty associated with the intervention effect had the greatest impact on the model.
As far as is known to the authors, this is the first health economic evaluation of a health promotion intervention targeting physical activity and healthy eating in individuals with mental disorders. Such research is important as it provides payers and governments with better insights how to spend the available resources in the most efficient way. Further research examining the cost-effectiveness of health promotion targeting physical activity and healthy eating in individuals with mental disorders is required.

"The nature of the mental illness may also affect motivation to change their lifestyle . Programmes to address risk factors such as smoking or obesity have had only limited impact [20,21]. Interventions made available by mainstream campaigns do not seem to address the health needs of people with serious mental illness . "
[Show abstract][Hide abstract] ABSTRACT: People with serious mental illness are at an increased risk of physical ill health. Mortality rates are around twice those of the general population with higher levels of cardiovascular disease, metabolic disease, diabetes, and respiratory illness. Although genetics may have a role in the physical health problems of these patients, lifestyle and environmental factors such as smoking, obesity, poor diet, and low levels of physical activity play a prominent part.
A qualitative grounded theory approach was used to understand the problems experienced by these individuals when asked to attend a healthy living programme. Three main areas were explored: the influence of potential barriers, health problems, and general attitudes towards healthy living.
Thirteen patients were interviewed during the study. Many did not recall receiving an initial invitation letter to the programme. Several believed that there was no necessity to attend as they had already had recent routine health checks by their general practitioner. The patients' current level of mental and physical health was important with symptoms such as depression, anxiety or arthritis affecting interest in the programme. Patients described that they found smoking enjoyable or calming in its effect. Dietary intake was determined by taste or gaining pleasure in eating certain types of food. Several lessons were learnt during this research that may aid future research and practice. Participation seemed to be better if the approach was first made by the patient's own community keyworker. This contact may have provided a greater opportunity to explain the purpose and importance of the programme. Alternative appointments should be considered when certain patients are in better physical and mental health. Healthy living programmes need to be flexible and adaptive to individual patient needs. Assistance from their community worker may help engagement. Simple measures may improve participation and reduce potential barriers.
These findings highlighted some of the problems encountered by patients when attempting to participate in a healthy living programme. These results may be useful when implementing future healthy living interventions for patients with serious mental disorders.
"Of the 16 similar studies of educational interventions, reviewers identified 6 studies that may be able to be implemented in the primary care setting
[42,51,53,56,63,65]. Those studies of interventions that might not be appropriate for primary care include interventions that were too long
[45,47,61], provided products or services that might not be available in primary care settings
[43,48,55,62,71] or required patients to have not yet developed physical risk factors prior to the intervention
[Show abstract][Hide abstract] ABSTRACT: Individuals with major psychotic and/or affective disorders are at increased risk for developing metabolic syndrome due to lifestyle- and treatment-related factors. Numerous pharmacological and non-pharmacological interventions have been tested in inpatient and outpatient mental health settings to decrease these risk factors. This review focuses on primary care-based non-pharmacological (educational or behavioral) interventions to decrease metabolic syndrome risk factors in adults with major psychotic and/or affective disorders.
The authors conducted database searches of PsychINFO, MEDLINE and the Cochrane Database of Systematic Reviews, as well as manual searches and gray literature searches to identify included studies.
The authors were unable to identify any studies meeting a priori inclusion criteria because there were no primary care-based studies.
This review was unable to demonstrate effectiveness of educational interventions in primary care. Interventions to decrease metabolic syndrome risk have been demonstrated to be effective in mental health and other outpatient settings. The prevalence of mental illness in primary care settings warrants similar interventions to improve health outcomes for this population.
