Abstract Metabolic disturbances commonly occur with serious mental illness (SMI). Strategies for weight management include group education, peer support, and follow up. This study evaluated the effects of group peer support on body weight, Confidence and Conviction (C&C), diet quality and health-related quality of life in a mental health setting. Fourteen participants [aged 51.7 + /− 12.2 years; four male ten female] who were unable to achieve and maintain 5% weight loss were recruited from a metabolic clinic at a mental health care facility. Weight, C&C, Dietary Screener Questionnaire (DSQ), and 36-item Short Form Survey Instrument (SF-36) were collected at baseline, 3, 6, and 12 months. SF-36 showed significant improvement in Vitality/Energy (−3.823, p = 0.003) and General Health Perception (−2.919, p = 0.014) at 3 months, significant decrease in Physical Functioning (-2.391, p = 0.048) and significant improvement in Pain (−2.885, p = 0.023) from baseline to 12 months. DSQ showed an inverse association between C&C and sugar intake.
Introduction Metabolic syndrome is defined as at least three of the following: dysglycemia, hypercholesterolemia, hypertension, abdominal obesity, and obesity. It affects approximately one in five Canadians and causes increased morbidity and mortality resulting from cardiovascular disease, stroke, and diabetes (Riediger and Clara 2011, pp. 1127–1134). Besides the potential personal consequences, obesity is a chronic illness that is an increasing burden on the Canadian healthcare system and workforce. According to the Public Health Agency of Canada, the total economic cost of obesity was

$4.6 billion in 2008, a $735 million dollar increase from 2000 (Public Health Agency of Canada 2011). The relationship between metabolic disease and mental illness is well established and is attributed to a variety of factors including biology, antipsychotic treatment, psychosocial factors such as income and local food environments, and modifiable lifestyle factors such as nutrition, physical activity, and smoking (Simon et al 2006). Having a mental health issue increases the chance of also having obesity by 2–3 times and increases the risk of dying from an obesity-related illness by up to 38%, which translates into a life expectancy that is reduced by 15–20 years
