Medscape (1/15, Melville) reports that people “with eating disorders have been found to be at increased risk for suicide attempts or death by suicide, even after adjustment for psychiatric comorbidities such as depression,” a study published online Jan. 13 in JAMA Psychiatry indicates. After analyzing data from “a Swedish national birth cohort of 2,268,786 individuals born between January 1979 and December 2001 who were followed from the age of six years,” researchers found that “the risk is notably increased when a close family member also has an eating disorder.”

The Washington Post (1/18, Ingraham) “Wonkblog” reports that research has “found no evidence” that teen “marijuana use leads to a decline in intelligence.”

The AP (1/19, Ritter) reports that in arriving at that finding, researchers “focused on 3,066 participants who were given a battery of intelligence tests at ages 9 to 12 – before any of them had used marijuana – and again at ages 17 to 20.” The majority of tests “revealed no difference between the two groups.” Nora Volkow, MD, director of the National Institute on Drug Abuse, “said that while the study has some limitations, it is important and deserves to be followed up with more research.”

HealthDay (1/19, Thompson) reports that despite mass shootings that have “prompted agony, anger and angst in the United States,” the US government continues to have a ban on funding for research into gun violence. HealthDay reports that “without that funding, experts say, crucial questions on gun safety and gun violence have been left unanswered.” Using data from the Centers for Disease Control and Prevention, an editorial in the New England Journal of Medicine “noted that more than 33,000 people died from gunshot injuries and more than 84,000 were wounded in 2013.”

On its “Morning Edition” program and in its “Shots” blog, NPR (1/19, Neighmond) reports that an increasing number of “adults over the age of 50” are being diagnosed for the first time with attention-deficit/hyperactivity disorder (AD/HD). In the case of adults, “the problem is not disruptive behavior or keeping up in school.” Instead, “it’s an inability to focus, which can mean inconsistency, being late to meetings or just having problems managing” tasks on a daily basis.

Meanwhile, MedPage Today (1/19, Blum) reports that adults whose AD/HD remains undiagnosed may “have impaired quality of life, productivity, and functioning compared with those who don’t have such symptoms, researchers reported” at the American Professional Society of AD/HD and Related Disorders (APSARD) meeting. In the study, which involved “more than 22,000 adults who had responded to the 2013 National Health & Wellness Survey,” adults with “AD/HD symptoms had significantly worse quality of life than those without symptoms as measured by the EQ-5D-5L index in adjusted analyses.”

On its front page, the New York Times (1/17, A1, Kolata, Cohen, Subscription Publication) reported, “Drug overdoses are driving up the death rate of young white adults in the United States to levels not seen since the end of the AIDS epidemic more than two decades ago.” According to a New York Times analysis of death certificates, “the rising death rates for those young white adults, ages 25 to 34, make them the first generation since the Vietnam War years of the mid-1960s to experience higher death rates in early adulthood than the generation that preceded it.”
