ARFID: A New (And Underdiagnosed) Eating Disorder

Symptoms seem to be caused by something that happened in early life.

Children can be picky eaters, of course. But their fussiness can grow out of control—no texture, no color, nothing solid—becoming a disorder and leading to serious health issues.

Now there's a name for it, ARFID, which stands for “avoidant/restrictive food intake disorder.” It’s different from other “well-known” eating disorders like anorexia nervosa because it doesn’t have to do with distorted body image or a desire to lose weight, and most people diagnosed with the disorder are children. Symptoms seem to be caused by something that happened in early life—a choking or vomiting event, an unhealthy relationship with a caretaker, or psychosocial problems such as depression or anxiety. A higher percentage of ARFID occurs in boys than other eating disorders, but still, most of the children diagnosed (70%) are girls.

The new category was added to the DSM-5—the Diagnostic and Statistical Manual of Mental Disorders, 5th edition—in May 2013, making the term still relatively unknown. A recent study published in the Journal of Adolescent Health takes stock of the newly coined term so that pediatricians, mental health professionals, and parents can provide better help. Experts behind the study are hoping to create more awareness.

“ARFID is not just about picky eating—it's a very challenging diagnostic category in the DSM-5,” said co-author Dr. Debra Katzman, a staff physician in the Eating Disorders program at the Hospital for Sick Children in Canada.

ARFID is complicated to treat, and must address both the medical aspects and psychosocial issues. “If left untreated, children and teens may be left with serious, long-term complications,” Katzman said. About 13 percent of the patients seen in pediatric eating disorder programs like SickKids are now diagnosed with ARFID.

The experts hope that creating awareness about ARFID will help with its prevention and treatment, especially where it counts: the home. “Concerned parents should talk to their child’s pediatrician or family doctor early on, rather than letting the problem persist for months or even years,” said co-author Dr. Mark Norris.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."

The Connors family, two coupes from the United Kingdom, one with a three-month old baby and the other with twin two-year-olds, were on vacation in Canada when the U.S. Immigration and Customs Enforcement (ICE) turned their holiday into a 12-plus day-long nightmare.

On October 3, the family was driving near the U.S.-Canada border in British Columbia when an animal veered into the road, forcing them to make an unexpected detour.

The family accidentally crossed into the United States where they were detained by ICE officials in what would become "the scariest experience of our lives," according to a complaint filed with the inspector general of the Department of Homeland Security.

The old saying goes something like, "Possessions don't make you happy." A more dire version is, "What you own, ends up owning you."

Are these old adages true or just the empty words of ancient party-poopers challenging you not to buy an iPhone 11? According to a new study of 968 young adults by the University of Arizona, being materialistic only brings us misery.

The study examined how engaging in pro-environmental behaviors affects the well-being of millenials. The study found two ways in which they modify their behaviors to help the environment: they either reduce what they consume or purchase green items.
