Too many American children are already overweight and the worrying forecast is for child obesity rates to rise. While the unprecedented rise in body weight over the past two decades has been well documented, less attention is paid to future projections of the US population distribution of body mass index (BMI). This study estimates that while levels of obesity will remain high but stable among US adults, on the contrary, continued growth in the prevalence of the highest BMI category for children is anticipated. These predictions can serve to be an integral component of policy assessments that target one of the causative factors of obesity.

Everyday and prospective memory deficits in ecstasy/polydrug users
Have you ever forgotten to post an important letter or let an appointment slip your mind? A new study from UK researchers suggests that for those who regularly use ecstasy or other recreational drugs, this kind of memory lapse is more common.

The results indicate a link between these recreational drugs and an impairment of prospective memory – remembering to remember to do tasks.
