Introduction & Objective: The purpose of this study is to determine the impact of socio-economic factors on bariatric and metabolic surgery, beyond repeated studies on saving costs of obesity, its complications and health care issues. Materials & Methods: The present research is a case-control study. The studied population included candidates for bariatric and metabolic surgery in educational-medical hospitals of Kermanshah province in 1402, who were studied in two intervention and control groups. Data collection has been done with two tools, interview and questionnaire. After collecting the data, SPSS 25 statistical software was used to organize and analyze the data. Results: In both groups, the frequency of female patients was higher than male. Group 1 patients reported higher work capacity (employment status, average weekly working hours and average monthly income). In the first group, 42.1% of them were employed; But in group 2, only 31.58% of patients were employed. The average weekly working hours in group 1 was 37.2±6.4 hours and in group 2 it was 28.9±12.4 hours. The average monthly income of group 1 was 110±25 million Rials and for group 2 it was 90±15 million Rials. The level of participation in sports activities in group 1 was equal to 39.47% and group 2 was equal to 10.53%. 42% of group 1 patients and 7% of group 2 patients stated that they are significantly active in social life. Group 1 received less medical services and consequently incurred less costs. There was a significant difference between the two groups in visiting hospitals. Conclusions: After performing bariatric and metabolic surgeries and undergoing recovery, people have shown more work capacity (job status, average weekly working hours and average monthly income); The increase in the employment rate, the increase in the average working hours per week, the increase in the income and the decrease in receiving sick leave all indicate the effectiveness of these surgeries on the employment status of people. Also, increasing participation in sports, cultural and social activities shows the improvement of personal and social conditions of people after obesity and metabolic surgeries.obesity and metabolic surgeries.
