AbstractWith the aim of comparing the acceptance of milk obtained from cloned, genetically modified (GM) and conventionally bred cows among working adults and university students, and identifying and characterizing typologies among both subsamples in terms of their preferences, a survey was applied to 400 people in southern Chile, distributed using a simple allocation among the subsamples. Using a conjoint analysis, it was found that consumers preferred milk from a conventional cow. Using a cluster analysis, in both subsamples two segments sensitive to production technology were identified. Rejection of cloning was greatest among university students, whereas a higher proportion of working adults rejected GM. The segments differed in terms of area of residence, knowledge about GM, and milk consumption habits. Contrary to what was expected, no differences were found according to education, gender or degree of satisfaction with food-related life.

Background: There is conflicting evidence about the emotional impact of bariatric surgery among obese individuals. Aim: To evaluate anxiety, depression and self-concept, before and after bariatric surgery among patients with morbid obesity. Material and Methods: Fifteen males and 5 females aged 28 to 61 years with a mean body mass index of 42.6 ± 5 kg/m², were studied. Grid Technique (TR), Personal Self Evaluation Questionnaire (OQ-45.2) and Anxiety Sate-Trait Inventory (STAI) were applied before and six months after bariatric surgery. Results: After surgery, the scores of self-esteem, well-being, flexibility, attraction, self-acceptance, confidence and guilt improved significantly. STAI and OQ-45.2 anxiety and depressive symptoms assessment were in the normal range before and after surgery. However, after surgery, there was a significant decrease in these sub scales in the OQ-45.2. No significant changes in anxiety measured using the STAI, were observed after surgery. Conclusions: Six months after bariatric surgery, positive changes were found in self-concept, and overall well-being.
