Results The results of the meta- analysis show an effect toward the experimental group .

Conclusions When compared with treatment as usual in psychotic patients , preventive and individual lifestyle interventions that include diet and physical activity generally prove to be effective in reducing weight .
This percentage is below the 5 % to 10 % weight loss deemed sufficient to improve weight-related complications such as hypertension , type II diabetes , and dyslipidemia .
However , it is reported that outcomes associated with metabolic risk factors may have greater health implication s than weight changes alone .
Background Psychiatric patients have more physical health problems and much shorter life expectancies compared to the general population , due primarily to premature cardiovascular disease .
A multi-causal model which includes a higher prevalence of risk factors has provided a valid explanation .
It takes into consideration not only risks such as gender , age , and family history that are inherently non-modifiable , but also those such as obesity , smoking , diabetes , hypertension , and dyslipidemia that are modifiable through behavioural changes and improved care .
Thus , it is crucial to focus on factors that increase cardiovascular risk .
Obesity in particular has been associated with both the lifestyle habits and the side effects of antipsychotic medications .
The present systematic review and meta- analysis aims at collecting and updating available evidence on the efficacy of non-pharmacological health promotion programmes for psychotic patients in r and omised clinical trials .
Nutritional intervention to prevent weight gain in patients commenced on olanzapine: a randomized controlled trial.
OBJECTIVE Olanzapine is the most commonly prescribed atypical antipsychotic medication in Australia . Research reports an average weight gain of between 4.5 and 7 kg in the 3 months following its commencement . Trying to minimize this weight gain in a population with an already high prevalence of obesity , mortality and morbidity is of clinical and social importance . This r and omized controlled trial investigated the impact of individual nutrition education provided by a dietitian on weight gain in the 3 and 6 months following the commencement of olanzapine . METHOD Fifty-one individuals ( 29 females , 22 males ) who had started on olanzapine in the previous 3 months ( mean length of 27 days + /- 20 ) were recruited through Peninsula Health Psychiatric Services and were r and omly assigned to either the intervention ( n = 29 ) or the control group ( n = 22 ) . Individuals in the intervention group received six 1 hour nutrition education sessions over a 3-month period . Weight , waist circumference , body mass index ( BMI ) and qualitative measures of exercise levels , quality of life , health and body image were collected at baseline at 3 and 6 months . RESULTS After 3 months , the control group had gained significantly more weight than the treatment group ( 6.0 kg vs 2.0 kg , p < or = 0.002 ) . Weight gain of more than 7 % of initial weight occurred in 64 % of the control group compared to 13 % of the treatment group . The control group 's BMI increased significantly more than the treatment group 's ( 2 kg/m(2)vs 0.7 kg/m(2 ) , p < or = 0.03 ) . The treatment group reported significantly greater improvements in moderate exercise levels , quality of life , health and body image compared to the controls . At 6 months , the control group continued to show significantly more weight gain since baseline than the treatment group ( 9.9 kg vs 2.0 kg , p < or = 0.013 ) and consequently had significantly greater increases in BMI ( 3.2 kg/m(2)vs 0.8 kg/m(2 ) , p < or = 0.017 ) . CONCLUSION Individual nutritional intervention provided by a dietitian is highly successful at preventing olanzapine-induced weight gain
