Physical Inactivity Poses Greatest Health Risk to Americans (PhysOrg)

Speaking at APA’s 117th Annual Convention, Steven Blair, PED, called Americans’ physical inactivity “the biggest public health problem of the 21st century.”

* * *

Research has shown approximately 25 percent to 35 percent of American adults are inactive, Blair said, meaning that they have sedentary jobs, no regular physical activity program and are generally inactive around the house or yard. “This amounts to 40 million to 50 million people exposed to the hazard of inactivity,” Blair said in an interview. “Given that these individuals are doubling their risk of developing numerous health conditions compared with those who are even moderately active and fit, we’re looking at a major public health problem”…More

Chinese Acupuncture Affects Brain’s Ability to Regulate Pain (ScienceDaily)

Using brain imaging, a University of Michigan study provides novel evidence that traditional Chinese acupuncture affects the brain’s long-term ability to regulate pain.

The results appear online ahead of print in the September Journal of NeuroImage.

In the study, researchers at the U-M Chronic Pain and Fatigue Research Center showed acupuncture increased the binding availability of mu-opoid receptors (MOR) in regions of the brain that process and dampen pain signals – specifically the cingulate, insula, caudate, thalamus and amygdala…More

DEET’s Nastiness Extends to Humans (US News & World Report)

DEET, the active ingredient in many bug repellents, doesn’t only cripple mosquitoes—it also meddles with mammals. A new study examining DEET’s effects on insects, mice and human proteins reports that the chemical interferes with a prominent central nervous system enzyme. This effect is magnified when exposure to DEET is combined with exposure to certain pesticides, researchers report online August 4 in BMC Biology.

The results are consistent with previous studies, says Bahie Abou-Donia of the Duke University Medical Center in Durham, N.C, who was not involved in the new work.

“DEET is a good chemical for protection against insects,” he says. “But prolonged exposure results in neurological damage, and this is enhanced by other chemicals and medications”…More

“No Doubt” Sunbeds Cause Cancer (BBC)

There is no doubt using a sunbed or sunlamp will raise the risk of skin cancer, say international experts.

Previously, the International Agency for Research on Cancer (IARC) assessed sunbeds and sunlamps as “probably carcinogenic to humans.”

But it now says their use is definitively “carcinogenic to humans.”

Campaigners believe the move, announced in the journal Lancet Oncology, will increase pressure for tighter industry regulation of sunbed use.

The new assessment puts sunbed use on a par with smoking or exposure to asbestos…More

Another Source of Phthalate Exposure: Pills (

A new study finds that a single tablet of an over-the-counter medication can raise the levels of phthalates in the body by 100 fold before being quickly eliminated.

The protective layer that coats the outside of drug capsules contains enough of a phthalate to drive levels in those taking the drugs above the daily intake limits designated by food regulatory agencies in Europe.

While the phthalate and its breakdown products leave the body within one to three days, longterm use could keep their levels elevated and raise the risk of health effects associated with the endocrine disruptors. Taking phthalates out of medicines would limit exposure, say the study’s authors…More

Optimism Appears to Lower Women’s Risk of Death, Heart Disease (ScienceDaily)

Optimistic women have a lower risk of developing heart disease or dying from any cause compared to pessimistic women, according to research reported in Circulation: Journal of the American Heart Association.

Researchers also reported that women with a high degree of cynical hostility — harboring hostile thoughts toward others or having a general mistrust of people — were at higher risk of dying; however, their risk of developing heart disease was not altered.

“As a physician, I’d like to see people try to reduce their negativity in general,” said Hilary A. Tindle, M.D., M.P.H., lead author of the study and assistant professor of medicine at the University of Pittsburgh. “The majority of evidence suggests that sustained, high degrees of negativity are hazardous to health”…More
