Impact of Strategies for Preventing Obesity and Risk Factors for Eating Disorders among Adolescents: A Systematic Review.

An effective behavior change program is the first line of prevention for youth obesity. However, effectiveness in prevention of adolescent obesity requires several approaches, with special attention paid to disordered eating behaviors and psychological support, among other environmental factors. The aim of this systematic review is to compare the impact of two types of obesity prevention programs, inclusive of behavior change components, on weight outcomes.

Unhealthy weight control behaviors, disordered eating, and body image dissatisfaction in adolescents from São Paulo, Brazil.

Objective: To identify the frequency of disordered eating (DE) and unhealthy weight control behaviors (UWCB) among adolescents and associations with age, sex, actual weight status, perceived weight status, and body image dissatisfaction.

Methods: Cross-sectional study of 1,156 adolescents. DE was assessed using a specific self-report questionnaire, UWCB by specific behaviors that were not typically recommended for weight management, and body dissatisfaction by Stunkard's silhouettes.

To identify food sources of shortfall nutrients consumed by adolescents (n = 3156), data from the National Health and Nutrition Examination Survey (NHANES) (2011-2014) were used. Some of the food groups commonly consumed by adolescents made a significant contribution to shortfall nutrient intakes in the diet. Many food sources that provided significant amounts of shortfall nutrients were from foods that also provided nutrients to limit.

Attitudes toward health and taste of food among women with bulimia nervosa and women of a non-clinical sample.

Taste preferences and health concerns play important roles in determining eating attitudes, thus influencing food choices. Disordered eating attitudes are common among women, and can lead to the development and maintenance of eating disorders (ED). Attitudes toward health and taste of food among ED patients and its comparison with non-clinical women are not well known, and this knowledge could improve eating interventions.

The role of selenoproteins in cancer.

Evidence has shown that metabolic disorders are common in tumor cells, leading to increased oxidative stress. The increase in the production of reactive oxygen species (ROS) associated with low antioxidant activity has been related to several types of cancer. Selenium, an antioxidant micronutrient, may function as an antimutagenic agent, preventing the malignant transformation of normal cells.
