Comparison of Perceived Weight Discrimination between Polish and German Patients Underwent Bariatric Surgery or Endoscopic Method versus Conservative Treatment for Morbid Obesity: An International Multicenter Study.

Objectives: The aim of this study was to compare the level of discrimination among patients with obesity living in Poland and Germany. Methods: This was a retrospective cross-sectional international multicenter survey study including 564 adult participants treated for morbid obesity at selected healthcare facilities in Germany (210 patients) and in Poland (354 patients). Discrimination was evaluated using a custom-made questionnaire based on the related literature. Results: The level of obesity discrimination did not differ between German and Polish patients (p = 0.4282). The presence of obesity was reported to be associated to a large or a very large extent with the feeling of social exclusion and discrimination by 46.63% of German participants and 42.09% of Polish ones (p = 0.2934). The mean level of discrimination related to the lack of employment was higher in patients who underwent bariatric surgery or endoscopic method than in those who underwent conservative treatment (for Germany: 2.85 ± 1.31 (median, 3) vs. 2.08 ± 1.31 (median, 1), p = 0.002; for Poland: 2.43 ± 1.15 (median, 2) vs. 1.93 ± 1.15 (median, 1), p = 0.005). The level of discrimination was associated with sex, age, the degree of obesity, and treatment-related weight loss (p < 0.05). Conclusions: Our findings confirm that obesity significantly affects the social and economic well-being of patients. There is a great need to reduce weight stigma and to take measures to alleviate the socioeconomic and psychological burden of obesity.
