HealthDay (11/28, Mozes) reports, “Despite concerns to the contrary, American children do seem to be getting adequate sleep,” according to a study published online Nov. 26 in the Archives of Pediatrics & Adolescent Medicine. “The finding stems from an in-depth look at current sleep norms among infants and children, as reflected by data collected in 1997 — with follow-ups in 2002 and 2007 — by a large National Science Foundation survey that set out to assess behavioral and mental health development from birth through age 18.” The study’s lead author stated, “Our estimates are in line with the amount of sleep recommended for children by the [US] Centers for Disease Control and Prevention, which suggests that children in the US are getting an appropriate amount of sleep on average.”

The Time (11/26, Szalavitz) “Healthland” blog reports, “Critics have long feared that stimulants simply drug children” with attention-deficit/hyperactivity disorder [AD/HD] “into submission, turning youngsters into compliant robots with no will to engage in defiant behavior.” However, UK researchers “interviewed 151 American and British children aged nine to 14 who were taking medication for AD/HD between 2008 and 2010. Their conclusion? ‘On balance, children report that stimulant drugs improve their capacity for moral agency,'” the study authors wrote, “explaining that most felt the drugs allowed them to make better choices.”

The Washington Post (11/24, Whoriskey) reported that in a review of articles published in the New England Journal of Medicine, “60 were funded by a pharmaceutical company, 50 were co-written by drug company employees and 37 had a lead author, typically an academic, who had previously accepted outside compensation from the sponsoring drug company in the form of consultant pay, grants or speaker fees.” One reason for that is that “since about the mid-1980s, research funding by pharmaceutical firms has exceeded what the National Institutes of Health spends.” The Post noted that in 2011, spending totals were $39 billion from industry and $31 billion from the NIH, and the Post adds that “over the past decade corporate interference has repeatedly muddled the nation’s drug science, sometimes with potentially lethal consequences.” As examples, the Post cites the “controversies over blockbuster drugs…erupted amid charges that the companies had shaped their research to obscure the dangerous side effects.”

Medwire (11/24, McDermid) reported that according to a study published online Nov. 22 in the journal The Lancet Neurology, “the true incidence of traumatic brain injury (TBI) is about sixfold higher than official figures state.” For the study, researchers “used sources including hospitals, brain imaging records, family doctors, prisons, traffic accident records, coroner and autopsy records, and accident records of schools and sports centers” to find that “the incidence of any TBI was 790 per 100,000 person-years, age-standardized to 811 per 100,000 person-years. From this, the team estimates that 54-60 million people worldwide have a TBI each year, with 2.2-3.6 million people having moderate or severe injury.”
