Jhanvi Humber River Regional Hospital, Toronto, Ontario, Canada Compared to conventional weight loss methods, bariatric surgery is one the most effective methods of achieving long-term weight loss in the morbidly obese population. The Roux-en-Y gastric bypass procedure has become a well-accepted tool in the treatment of obesity in Canada. Although the primary mechanisms of weight loss are obtained by the restrictive and malabsorptive nature of the surgery, its neuroendocrine effects cannot be dismissed. Several gastrointestinal hormones have demonstrated their effects on appetite, i.e., glucagonlike peptide-1 (GLP-1), peptide tyrosine-tyrosine (PYY), leptin, ghrelin, cholecystokinin (CCK), and incretins. This review of the current published literature reveals the effect of the Roux-en-Y gastric bypass procedures on different gut hormone levels, and the alteration in neuroendocrine regulation of energy homeostasis. 195 Families in action: a culturally and linguistically sensitive community-based obesity prevention program for Latin-canadian children and their families D.S. Battram, B. Harvey, S.B. Harris, G. Mandich, C. Beynon, and M. He Brescia University College, London, Ontario, Canada background: “Westernization” affects many new immigrants as they adjust to a new Western culture. While this is thought to be due to changes in dietary intake and physical activity, new immigrants face additional challenges that can confound this issue (e.g., food insecurity and limited access to health resources). In light of these additional complexities, an innovative approach to address this issue is needed. Purpose: To implement a culturally and linguistically sensitive community-based program to prevent obesity in Latin-Canadian children. Methods: Overweight and obese children, and their families, participated in a six-month intervention, designed to address each families’ unique challenges and needs. The intervention was delivered by trained lay leaders without the researchers’ direct involvement, and aimed to educate families about healthy eating and active living; provide access to healthy foods and physical activity opportunities; and address cultural, social, and economic determinants of health. Changes in BMI z-scores were evaluated at baseline and at six months post intervention. results: At 0.3 years old and had a BMI Z±baseline, children (n = 55) were 9.1 0.1. Preliminary findings revealed that at six months (n =±score of 1.5 0.1. Lessons learned from±14), BMI z score was decreased by 0.03. Implementing this community-based intervention includes challenges of consistent data collection and participant follow-up. conclusion: A culturally and linguistically sensitive communitybased intervention that targets not only unhealthy behaviours, but also key social and economic issues facing new immigrant families, faces many challenges. However, it still may offer a promising strategy for childhood obesity prevention. 196 Perceived vs. actual weight status: self-rated health and life satisfaction among canadian adults K.M.

and Department of Community Health and Epidemiology, Queen’s University, Kingston, Ontario, Canada; 3Department of Geography, and Department of Community Health and Epidemiology, Queen’s University, Kingston, Ontario, Canada Introduction: Obesity is associated with significant impairments in health-related quality of life (HRQL). Since self-rated health (SRH) and general-life satisfaction (GLS) are perceived constructs, they might be more strongly related to perceived weight status, vs. actual weight status. The objectives were to assess agreement between self-reported BMI and perceived weight status in Canadian adults, and to investigate their association to SRH and GLS as indicators of HRQL. Methods: Cross-sectional data included 87,545 adults ages 18-65 years from the 2005 Canadian Community Health Survey. Agreement between self-reported BMI and self-perceived weight status was assessed. Prevalence of fair-or-poor SRH and less-than-satisfied GLS was estimated by actual and perceived weight status, and adjusted logistic regression used to assess the odds of adverse outcomes. results: Overall agreement between self-reported BMI and perceived weight status was only moderate (females: K=0.58; males: K=0.42). The lowest prevalences of adverse SRH and GLS were in those who reported a healthy weight both in terms of BMI and perceived weight status. BMI status generally did not have a large effect on prevalence or odds of adverse SRH or GLS for those who perceived their weight as “about right.” However, perceptions of underweight or overweight were associated with increased prevalence and odds of adverse SRH and GLS, regardless of BMI status. conclusions: Adults’ weight status perceptions do not necessarily agree with their actual weight status, even when the latter is selfreported. While both perceived and actual weight status may play a role in SRH and GLS, perceptions may have stronger influence, and should be considered when informing obesity-targeted policies and programs. 197 Eating patterns of morbidly obese individuals scheduled for bariatric surgery Mitchell A-M, and Paquette M-C. Université de Montréal, Montréal, Québec, Canada Introduction: Morbid obesity is increasing rapidly in Canada, as rates have tripled (0.9 - 2.7%) from 1978 to 2004, and rates are twice as high in women in comparison to men. The present study seeks to highlight the main variables of the food and behavioural patterns of morbidly obese individuals, as little is known on this subject. Methods: The study took place in a bariatric surgery out-patient clinic, using the hospital charts to retrospectively collect data from the initial nutrition consult. The study included a total of 83 subjects (54 women and 29 men) from 16 to 62 years old, with BMI ranging from 39.5 82.3 kg/m2. The data were analyzed through SPSS 17.0. results: A majority of participants reported eating meals rapidly (under 15 minutes) and having difficulty identifying or responding to satiety and hunger signals. Many reported eating for reasons other than being hungry such as boredom, stress relief, etc. Dysfunctional eating patterns such as skipping breakfast were observed, and often compensated by excessive food consumption later during the day. Generally, meals were unbalanced in regards to CFGHE with frequent intake of caloriedense and processed foods. The daily protein intake was suboptimally distributed among meals, while refined carbohydrates were generally found to be consumed in excess. Before considering bariatric surgery, the majority of subjects in the study reported not seeing a registered dietitian, or had not taken part in a structured weight-loss program to address the issues that may lead to morbid obesity. conclusion: Improved understanding of the eating patterns of morbidly obese individuals will help to better cater to their needs by developing structured health programs with professionals, such as registered dietitians, to optimize health through better eating habits.
