Publication Long-term quality of life in patients with bariatric surgery evaluated with BAROS(2024) Palacio Agüero, Ana; Díaz-Torrente, Ximena; Zancheta, Camila; Reyes, Alejandra; Cosentino, Marcela; Almada, María JoséQuality of life (QoL) significantly improves in the short term after bariatric surgery (BS). However, evidence on the long-term QoL of patients with BS is limited. Aim: To analyze the long-term QoL of patients who underwent Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). Methods: We evaluated 257 patients from three private clinics in Santiago, Chile, with ~10-y since surgery. The Bariatric Analysis and Reporting Outcome System (BAROS) was used. Results: Median values for the BAROS score indicated good results of treatment:4.3 (2.3-6.0) and 4.1 (2.1-6.4) for RYGB and SG patients, respectively. The Moorehead-Ardelt Quality of Life (MAQoL) score was higher in patients with SG compared to RYGB (1.5 vs. 1.3, p = 0.047). A moderate, positive, and significant correlation was observed between the percentage excess weight loss and MAQoL score (rho= 0.48, p<0.001). Conclusions: Patients undergoing BS showed a good QoL even in the long term (~10 y).Publication Validation of the Chilean version of the Yale food addiction scale 2.0 in a non-clinical sample(2024) Díaz-Torrente, Ximena; Palacio Agüero, Ana; Valenzuela, Carina; Vergés, Alvaro; Gearhardt, Ashley N.Aims: The aim was to translate and culturally adapt the Yale Food Addiction Scale 2.0 (YFAS 2.0) to the Chilean population, evaluate its psychometric properties in a non-clinical sample, and assess the correlations between symptoms count of food addiction (FA) with demographic and anthropometric variables. Methods and participants: We evaluated 301 participants (59.1% women) with a mean age of 29.7 ± 12.4 years recruited from two universities and two businesses (non-clinical sample). The Chilean YFAS 2.0 was administered, and anthropometric measurements were carried out. The internal consistency of the items was estimated, and factor structure was tested by confirmatory factor analysis. Test-retest reliability was also examined. The correlations between symptoms count of FA and weight, waist circumference (WC), Body Mass Index (BMI), percentage of body fat (BF%), and lean mass were evaluated. Results: The Chilean YFAS 2.0 presented good internal consistency, and confirmatory factor analysis supported the one-factor structure, in accordance with the original version. The ICC indicated excellent test-retest reliability. The prevalence of FA was 10.3%, and the symptom count of FA was 2.1 ± 2.8. A small positive correlation between WC, BMI, and BF % and FA symptom count was found. Conclusion: The Chilean YFAS 2.0 may be a useful tool to investigate FA in Chile. Level of evidence Level V, cross-sectional descriptive study.Publication Food addiction in patients on weight loss treatment.(2024) Palacio Agüero, Ana; Cuello, Catalina; Díaz-Torrente, XimenaBackground: Food addiction (FA) is defined as hedonic eating behavior involving the consumption of highly palatable foods (i.e., ultra processed foods in quantities beyond homeostatic energy requirements). FA is present in a subset of patients with overweight or obesity and could contribute to the response to weight loss treatments. Aim: Determine FA in individuals that fulfil the criteria of FA as measured by the YFAS 2.0, and its association with anthropometric and body composition variables in a clinical sample of patients undergoing weight loss treatment. Also, to determine the most prevalent FA criteria. Methods: An observational, analytical, and cross-sectional study was conducted. Sampling was non-probabilistic, convenience based. A total of 158 participants were recruited from two clinical centers (private and public) focused on managing non-communicable chronic diseases. The Chilean version of YFAS 2.0 was administrated through the online REDCap platform. Anthropometric measurements were measured, and body mass index (BMI) was calculated. Results: The mean age was 47.8 (SD 14.9) and BMI 28.7 (SD 5.3) kg/m2. There were 12.7% patients who screened positive on the YFAS 2.0 Chilean version (3.2% for mild, 2.5% for moderate and 7.0% for severe), the mean symptom count was 2.2 (SD 2.6), with withdrawal being the most prevalent criterion (33.5%). FA patients had significantly higher body weight compared to non-FA subjects (p = 0.045). We observed a slight and significant correlation between FA symptom count and body weight (p = 0.020), waist circumference (p = 0.005), and BMI (p = 0.023). Conclusion: This is the first study in Chile that showed that FA was present in patients undergoing weight loss treatment and was associated with anthropometric measurements. In addition, it showed that withdrawal was the most prevalent criterion. Future studies should investigate whether the presence of FA and the withdrawal criterion could contribute to suboptimal clinical response to weight loss treatment.
