Much Like Television, Excessive Cell Phone Use Lowers Fitness Levels
Are you reading this on your smartphone? If so, it’s probably not doing your weight any good. A new study in the International Journal of Behavioral Nutrition and Physical Activity has linked cell phone use by college students to decreased physical activity and fitness levels. Much like watching television, cell phone use is a largely sedentary activity that is easy to get lost in. It can also lead to casual overeating. Researchers found the average student spent about five hours on the phone each day and sent hundreds of text messages. "We have to look at this similar to what happened in the industrial revolution and how it changed us," said Nancy Copperman, director of public health initiatives at North Shore-LIJ Health System, in Great Neck, N.Y. "A study like this raises the importance of how this technology affects how we move, eat and sleep. We have to look at the impact of technology on our health." Read more on technology.
Study Links Bipolar Disorder, Early Death
A new study showing that people with bipolar disorder are more likely to die early and from a variety of causes also illustrates the difficulty of treating the physical effects of the illness. "Whatever we're doing, these people are not dying (just) because of suicide. That's not the reason for increased mortality. That's a hard thing to get across," said David Kupfer, PhD, a professor of psychiatry at the University of Pittsburgh School of Medicine, who was not a part of the study. The study found that people with bipolar disorder—an estimated 1 to 5 percent of the global population—die about nine years earlier and are at higher risk for heart disease, diabetes, chronic obstructive pulmonary disorder, the flu and pneumonia. However, people who knew they were bipolar had the same death rates as those who were not, which suggests "that timely medical diagnosis and treatment may effectively reduce mortality among bipolar disorder patients to approach that of the general population," according to the study.

One Dose of ADHD Medication Improves Balance in Older Adults
A single dose of an attention deficit/hyperactivity disorder (ADHD) medication can improve the balance of older adults who have difficulty walking, according to a new study in The Journals of Gerontology. Methylphenidate (MPH) is also used to treat narcolepsy. Researchers at Ben-Gurion University of the Negev found that it can reduce the number and rate of step errors in both single and dual tasks. "Our results add to a growing body of evidence showing that MPH may have a role as a therapeutic option for improving gait and reducing fall risk in older adults," said Itshak Melzer of BGU's Schwartz Movement Analysis and Rehabilitation Laboratory, Department of Physical Therapy, Faculty of Health Sciences. "This is especially true in real-life situations, where the requirement to walk commonly occurs under more complicated, 'dual task' circumstances with cognitive attention focused elsewhere (e.g., watching traffic, talking) and not on performing a specific motor task."
