    The purpose of this study is to evaluate patients' quality of life and healthcare use before and after bariatric surgery and produce new, clinical data-based information on the cost-effectiveness of bariatric surgery. Healthcare resources are limited and expenditures have grown from year to year. Therefore it is important to make cost-effectiveness evaluations so that financial resources could be allocated properly. The research population consists of patients who have undergone gastric bypass or sleeve gastrectomy in the Hospital District of Helsinki and Uusimaa, during the years 2007-2009. The study population consists of 147 gastric bypass patients and 79 sleeve gastrectomy patients. In this study the decision analytic model, used in the Finohta study "Sairaalloisen lihavuuden leikkaushoito" was updated using actual, up-to-date information. The analysis was done using a decision tree and a Markov model with a time horizon of 10 years. The cost data in this study was based on actual data for the first two years after surgery. A forecast model was used to predict the costs for the years 3-10 after surgery. Patients' quality of life scores were based on real data for the years 1 (the year of operation) to 4. Quality of life scores for the other years were predicted. In the literature review section, international studies on the cost-effectiveness of bariatric surgery and its impacts on drug therapy were evaluated. The studies showed that the use of medicines, which were used to treat obesity-related diseases were lower in the surgery group. However, drugs used to treat vitamin deficiencies, depression and gastrointestinal diseases were higher in the surgery group. Most studies found that surgery is the most cost-effective way to treat morbid obesity. This study confirms the role of the bariatric surgery in the treatment of morbid obesity in Finland. Even though the healthcare costs were increased in the first two years after the operation, the conclusions of the Finohta study didn't change. The bariatric surgery is cheaper and more effective than ordinary treatment and the most cost-effective way to treat morbid obesity. The mean costs were 30 309 € for the gastric bypass, 31 838 € for the sleeve gastectomy and 36 482 € for ordinary treatment. The mean numbers of quality-adjusted life-years were 6.919 for the gastric bypass, 6.920 for the sleeve gastrectomy and 6.661 for ordinary treatment. However, there is demand for more information for the long-term effects, benefits and risks of the surgery. How much the surgery will actually save money, will be hopefully clarified in the long-term follow-up study, which should also include an actual control group.

    Background: Obesity has a multifaceted etiology that involves genetic, biological and behavioral factors, body growth, eating habits, energy expenditure and the function of adipose tissue. The present study aimed to expand upon knowledge about the relationships among obesity, emotions and eating habits in severely obese individuals using a case-control method. Methods: The subject group consisted of 112 individuals (81 females and 31 males) receiving a permanent disability pension primarily for obesity. The control subjects were randomly selected from the same area and were receiving a disability pension for a different primary illness. The controls were matched with the subjects by the place of residence, sex, age, the time since the pension was granted and occupation. Psychiatric interviews were conducted on all participants. The results were analyzed using the chi-squared test (X2-test) and the percent distribution. The subject and control groups were compared using the t-test for paired variables. Conditional logistic regression analysis was also conducted. Results: The emotional state of eating was significantly associated with quarrels and feelings of loneliness. The subjects suffered from night eating syndrome, which was associated with an increased risk of early retirement. Binge eating syndrome was observed more frequently in the study group. The subjects reported feeling increased hunger compared with the controls. A significant percentage of the subjects had a body mass index of≥40. No differences in eating habits were observed between the groups. Conclusion: This study provides information on the relationship between emotions and eating habits in obesity, which is a rarely studied topic. We believe that our study provides a novel and necessary overview of the associations among severe obesity, emotions and eating habits. © The Author(s).
