Weighing Words When Talking to Teens About Body Weight   Medscape (May 11, 2017) by Rebecca M. Puhl, PhD – Body shaming and weight stigma have become commonplace in our society. Decades of research evidence and high-profile examples highlighted in the media clearly demonstrate the presence of societal stereotypes and stigma against people who have a higher body weight. Unfortunately, youth who have a higher body weight are particularly vulnerable to weight stigma, most often in the form of teasing, victimization, and bullying. In fact, weight-based bullying has been documented as one of the most prevalent forms of bullying in youth and adolescents. … In our efforts to reduce societal weight stigma, the words that we use when talking about body weight are important. For example, adults report feeling stigmatized, negatively judged, and blamed when certain words, such as “obese,” “fat,” or “large” are used to describe their excess body weight. … more

Preventing Obesity and Eating Disorders in Adolescents   Pediatrics (August, 2016) – Obesity and eating disorders (EDs) are both prevalent in adolescents. There are concerns that obesity prevention efforts may lead to the development of an ED. Most adolescents who develop an ED did not have obesity previously, but some teenagers, in an attempt to lose weight, may develop an ED. This clinical report addresses the interaction between obesity prevention and EDs in teenagers, provides the pediatrician with evidence-informed tools to identify behaviors that predispose to both obesity and EDs, and provides guidance about obesity and ED prevention messages. The focus should be on a healthy lifestyle rather than on weight. Evidence suggests that obesity prevention and treatment, if conducted correctly, do not predispose to EDs. … more

At least five years after undergoing gastric bypass surgery, teens and young adults maintained significant weight loss but were at risk of nutritional deficiencies, particularly low iron, mild anemia and low vitamin D. The study also found low iron and low vitamin D in severely obese teens who did not undergo weight loss surgery. Those who didn’t have surgery also had low levels of protein in their blood.   more …

Obesity, depression linked in teen girls, new study shows.  ScienceDaily (Mar 21, 2014) – Depression and obesity have long been associated, but how they relate over time is less clear. New research shows that adolescent females who experience one of the disorders are at a greater risk for the other as they get older. It is unknown why no associations across time between the two disorders were found in male adolescents, but researchers hypothesize that it could be a result of different developmental processes leading to obesity and depression in males and females.   More …

Brain size may signal risk of developing an eating disorder   ScienceDaily (Aug 22, 2013) New research indicates that teens with anorexia nervosa have bigger brains than teens that do not have the eating disorder.

They found that girls with anorexia nervosa had a larger insula, a part of the brain that is active when we taste food, and a larger orbitofrontal cortex, a part of the brain that tells a person when to stop eating.   Link

Dieting youth show greater brain reward activity in response to food   ScienceDaily (May 2, 2013) — The story is a familiar one: most people are able to lose weight while dieting but once the diet is over, the weight comes back.
