AI Article Synopsis
- Obesity remains a significant global public health issue, and understanding factors like self-perception of body weight is essential for addressing it.
- An analytical cross-sectional study of 5483 Chilean participants found a low agreement between self-perceived body image and actual nutritional status, especially among women, those in rural areas, and individuals with lower education levels.
- The findings suggest that many Chileans underestimate their body weight, which can hinder efforts to recognize and address obesity through lifestyle changes and healthier eating habits.
Article Abstract
Introduction: obesity is a public health problem. No significant decrease in the prevalence of obesity has been globally observed. A better understanding of the factors that can influence obesity is necessary, one of them being self-perception of body weight. Objective: to determine the agreement between self-perception of body image and nutritional status in a Chilean population. Methods: an analytical cross-sectional study was carried out based on the Chilean National Health Survey 2016-2017. Nutritional status was measured by body mass index (BMI) and self-perceived body weight. Agreement was estimated by the kappa index and weighted kappa index. These indices were specified according to sociodemographic variable. Results: the total number of participants was 5483, with 51 % (95 % CI: 48.7-53.5) corresponding to women. Mean age was 43.2 years (95 % CI: 42.4-44.0). The kappa index showed a low concordance (kappa, 0.194; 95 % CI: 0.177 to 0.211) among women, people from rural areas, and subjects with fewer years of education. The global weighted kappa was 0.325; 95 % CI (0.168-0.482). Conclusions: underestimation of nutritional status can lead to negation of the problem generated by excess body weight. Recognizing nutritional status is a critical stage to initiate behavior changes and start having healthy eating habits. More than half of Chileans present distortion of body image, prevailing underestimation of body weight.

Background: Serum albumin (Alb) is an essential indicator of human physiological function, which can reflect the functionality of multiple organs, including the liver and kidneys. Presently, numerous studies have indicated that levels of blood albumin serve as important biomarkers for a range of respiratory illnesses. These findings can better guide clinical practice and disease prevention.

Objective: Intestinal transplantation (ITx) has become an accepted option for children with serious complications from intestinal failure and parenteral nutrition (PN) dependence. We aimed to assess long-term growth and nutritional outcomes in these patients. We also assessed factors influencing nutritional status and ability to wean off tube feedings (TFs) after ITx.

Ann Gastroenterol Surg
January 2025
Aim: The reconstruction methods after proximal gastrectomy (PG) are varied but not standardized. This study was performed to evaluate the short-term clinical outcomes between double tract reconstruction (DTR) and double flap technique (DFT).
Methods: We retrospectively reviewed and collected data of patients who underwent DTR and DFT after laparoscopic proximal gastrectomy (LPG), respectively, between January 2020 and March 2023.
Aim: In this study, we evaluated the difference in short-term outcomes and postoperative nutritional status between subtotal gastrectomy (sTG) and proximal gastrectomy (PG) to determine the optimal surgical treatment for early gastric cancer in the upper third of the stomach.
Methods: Patients who underwent laparoscopic or robotic sTG or PG at the Shizuoka Cancer Center in Shizuoka between January 2014 and December 2020 were enrolled in this retrospective study. Patient characteristics, surgical outcomes, endoscopic findings, and postoperative nutritional changes, including blood tests, body weight, psoas muscle, and subcutaneous and visceral adipose tissue, were measured and compared between the two groups.
